1.3 What is AS-Interface?
AS-Interface
AS-Interface ("AS-i" for short) stands for actuator sensor interface. It is an industrial field bus
system that retrieves the signals at the lowest field level.
Cost-effective alternative to standard wiring methods: the yellow AS-i cable
The sensors and actuators no longer need to be connected individually to the controller
via parallel cables, which is an extremely time-consuming process, but simply via one
joint AS-i cable.
The input signals are gathered from AS-i modules and automatically sent to an AS-i
master, which forwards the data to the controller (e.g. SIMATIC S7). At the same time,
the output signals travel in the opposite direction.
The AS-i cable also supplies the power for the modules and sensors.
The modules can be easily connected to the yellow AS-i flat ribbon cable by means of the
insulation displacement method so that they are protected against polarity reversal.
The following terminal devices can be connected to AS-i modules:
Binary sensors (e.g. proximity switches, positions switches, pushbuttons)
Binary actuators (e.g. valves, indicator lights)
Analog sensors (e.g. temperature sensors (KTY, PTC, NTC), level indicators)
Analog actuators (e.g. analog displays)
The following sensors and actuators with integrated AS-i slave can also be connected to
AS-i modules:
Control devices
Signal columns
Motor feeders
Position switches
Direct assembly
Since the AS-i field modules are available with housings with a high degree of protection
(e.g. IP67), they can be assembled in the immediate vicinity of sensors and actuators.
AS-i modules and sensors/actuators can be quickly and easily connected using short
prefabricated cables (e.g. M12 or M8 plug-in cables).
Modules with degree of protection IP20 are available for use in control cabinets.

AS-i logo
AS-Interface devices have the following logo:
Figure 1-1 The AS-Interface logo
Optimum quantity structure
AS-Interface is optimized in line with the data volume that fulfills the requirements of the
lowest field level. Up to 31 modules (standard slaves) each with four digital inputs and
outputs can be connected for each AS-i network. The cycle time here is max. 5 ms.
The number of modules can be doubled to 62 when modules with an extended addressing
mode (A/B slaves) are used.
Analog input and output modules are also available in addition to digital modules.
Safety-oriented signals (EMERGENCY STOP, door tumbler, two-hand operations etc.) can
also be transferred.
International standard
The AS-Interface concept was elaborated in 1992 by a consortium originally comprising
11 companies, including Siemens AG, in the area of industrial automation. Since then,
approx. 300 companies worldwide have helped create an established system with this
technology.
AS-Interface complies with the international standards EN 50295 and IEC 62026-2 for field
bus communication.
The system properties are defined in an open, manufacturer-independent manner in the AS-i
specifications (AS-i Spec. for short) by the umbrella organization AS-Interface Association.

1.4 The automation pyramid and deployment of AS-i
The automation pyramid levels
The automation pyramid is divided into three levels.
The control level
Here, individual automation islands are connected to each other to create larger units, e.g.:
Several machines in a hall
Several halls in a plant
Several plants in a company at different locations
Data exchange takes place in large data blocks and is not critical from a time perspective.
The field control level
At this level:
Central and distributed automation devices are used
Complex field devices are connected
Data is usually exchanged on a byte-dependent basis.
The actuator/sensor level
At this level, the most commonly-used components are connected:
Binary actuators
Simple analog devices
Data is usually exchanged on a bit-dependent basis.
Totally Integrated Automation
The Siemens Totally Integrated Automation (TIA) concept covers all the automation levels
and is optimized in line with the interfaces.
Siemens offers:
AS-Interface communication processors (CP) that can be installed directly in the
SIMATIC rack
Gateways (links) for transferring data from AS-Interface to PROFIBUS and PROFINET

1.5 Benefits of AS-Interface
The actuator sensor interface offers the following benefits:
No need for complex cable harnesses to the sensors and actuators
Smaller control cabinets due to the lack of I/O modules
Rapid installation thanks to the IP67 housing and AS-i insulation displacement method
Plug-in methods allows sensors and actuators to be connected without errors
Signals are mapped in the PLC in the same way as for standard I/O modules
Comprehensive range of diagnosis options covering even individual modules
Modules can be replaced while the system is live
These benefits not only help cut the cost of configuration, installation, documentation, and
maintenance, but also reduce downtime.

AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 35
3.1 Components required for creating AS-Interface system
Key components of an AS-Interface system
An AS-Interface essentially comprises four components:
1. AS-Interface master
The AS-Interface master (in this example: communications processor CP343-2 P)
controls data exchange with the connected nodes (slaves).
2. AS-Interface slaves/modules
All the nodes that are addressed by the master are called "slaves". In this example, K45
digital I/O modules are used to which the sensor (inductive proximity switch) and an
actuator are connected.
3. AS-Interface cable
The AS-Interface cable, an unshielded two-wire cable, transfers the signals and power
supply for the sensors and actuators connected via AS-Interface. If necessary, the power
supply for actuators can be taken from the black shaped cable.
4. AS-Interface power supply unit
The AS-Interface power supply unit supplies the network electronics (AS-Interface
modules) and connected sensors. The integrated data decoupling ensures that the data
and power are kept separate, which means that data and power can be transferred in one
cable.
Note
AS-Interface power supply units are among the essential and functionally-critical
components of an AS-Interface network and cannot be replaced by conventional power
supply units!
The components required for creating the system described in this example are listed below.
If other components are used, the steps involved may differ from the description provided

3.3 Commissioning the AS-Interface system
Step-by-step guide to creating a fully-functional AS-Interface system
To commission a fully-functional AS-Interface system, we recommend that you carry out the
following steps:
1. Address the I/O modules with the addressing unit
2. Mount all the components on the DIN rail
3. Connect all the components to the AS-i bus.
4. Program the AS-i system in STEP 7.
5. Carry out a functional test.
Getting Started
3.4 Addressing the I/O modules
AS-Interface system
40 System Manual, 11/2008, 3RK2703-3BB02-1AA1
3.4 Addressing the I/O modules
Unique addressing
In the as-delivered condition, the address of each I/O module (slave) is set to 0. It is detected
by the master as a new slave that has not yet been addressed and, in this condition, has not
yet been integrated in standard communication/data exchange.
To enable data to be exchanged between the master and slaves, you have to assign a
unique address for all the slaves before creating the interface network. The following
addresses are used in this example:
Input module K 45 = address 1
Output module K 45 = address 2
Note
When addressing the slaves via the addressing socket, you must switch off the AS-i voltage
for safety reasons.
Steps
1. Unscrew the cap for the addressing socket on the
module.
2. Connect the module to the addressing unit
(3RK1904 2AB0).
3. Assign an address to the module.
Switch the selector switch to ADDR.
Press . The address of the connected module
is read and displayed.
Select the address with .
Transfer the address to the module with .
4. Remove the addressing cable with the cap.
5. Seal the addressing socket with the cap.

Properties of the AS-Interface cable
The AS-Interface cable connects all the network nodes.
The cable has two wires (ASI + and ASI -) and is unshielded.
The trapezoidal profile with the profiled lug ensures a high degree of protection against
polarity reversal (mechanical code).
The shaped cable transfers data and power.
The AS-Interface shaped cable offers a high degree of flexibility when you structure
network topologies, which means they can be optimized in line with physical conditions.
/LQH 6WDU 7UHH
0DVWHU 0DVWHU 0DVWHU
Line, star, tree as well as any other combination of topology configurations are possible.
The nodes can be connected at any point in the network.
Up to 62 slaves, one master, and up to four additional passive nodes (without their own AS-i
address) can be connected to a network.
No shielding is required. The cable must not be twisted. A line terminator is not required.
The total length of the cable is restricted to 100 m. A range of components (e.g. repeater,
extension plug) are available for extending the maximum length of the cable.
The nodes receive their power supply via the same cable with a rated voltage of 24 V DC
and a total current of up to 8 A.

Using cables that do not comply with AS-i specifications
If a cable that does not comply with the specifications above (shielded cable in particular) is
used as an AS-i cable, a correction factor of 1.3. must be taken into account when the length
of this cable is calculated.
From an electrical point of view, therefore, approx. 75 m of a non-compliant cable
corresponds 100 m of an AS-i-compliant cable.

Figure 4-1 AS-Interface power supply unit
Each AS-Interface power supply unit performs four functions.
Supplies the network with a rated voltage of 30 V DC
To ensure that 24 V DC can also be ensured at the end of the AS-Interface network, the
power supply unit has been specified with a rated voltage of 30 V.
This design permits a voltage drop of approx. 3 V via the AS-Interface cable and another
3 V in all the slaves where the data and power path must be separated again.
In principle, the current supplied to the AS-Interface network can be set as required. In
practice, approx. 8 A is a sensible setting due to the standard conductor cross-sections of
the AS-Interface cables.
Operating principle
4.2 Physical layer
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 57
Protective separation
AS-Interface is designed as a system for low voltages with protection separation (PELV:
"Protective Extra Low Voltage" to IEC 60364-4-41). For this reason, a power supply unit
that takes its primary voltage from 115 V AC or 230 V AC requires protective separation
between the primary and secondary voltage in accordance with the applicable IEC
standards.
The PELV protective measure means that there is no need for a PE conductor. Other
special shock-hazard measures are not required either.
Balancing the network
AS-Interface is operated as a symmetrical, ungrounded system. To ensure optimum
interference immunity against symmetrical coupled-in noise, the AS-Interface cable must
be designed to be as symmetrical as possible. A balancing circuit can be used for this
purpose. The "ground" connection must be grounded at a suitable point in the machine or
plant. With AS-Interface, only this point can be connected to ground (GND) directly.
Proper balancing means that the cable does not need to be shielded or twisted.
Data decoupling
The data decoupling network is normally integrated in the AS-Interface power supply unit.
It has two inductors of 50 µH each and two 39 Ω resistors connected in parallel. This
network ensures that data transfer is not short-circuited by the power supply. At the same
time, it converts the current pulses generated by the AS-Interface transmitters to voltage
pulses that can be detected by the AS-Interface receivers.

To transfer data, AS-Interface uses alternating pulse modulation (APM) with virtually
sine2-shaped current/voltage pulses, which means that the following prerequisites are
fulfilled:
The message signal is superimposed on the power supply for the actuators and sensors
and must be free of DC current.
The transmitter must be able to generate the signal as efficiently as possible.
Since the AS-Interface cable has a steeply-rising damping characteristic over the
frequency, the message signal must have a narrow band.
APM transfers the data serially in the baseband and is free of DC current.

2. With this coding type, the information regarding the level
switch is in the center of the bit. With a logical zero, the
signal in the center of the bit switches from "high" to "low"
(and vice versa with a logical one).
The send bit sequence is recoded as a bit sequence that
carries out a phase change whenever the send signal
changes (Manchester coding).

3. This bit sequence is converted to a send current.

4. The send current is converted by the inductor in the AS-i
power supply unit to a voltage, which can be detected by the
receiver:
When the send current increases, this results in a negative
voltage pulse (and vice versa).

5. The receiver detects these voltage signals on the cable
and converts them to the send bit sequence; it interprets the
first negative pulse as the start bit of a message.

6. Bit sequence received
The special shaping of the send current pulses means that the radiation of high-frequency
electromagnetic waves is reduced to the extent that cables that the non-shielded AS-i cable
complies with the prescribed limit values.
Alternating pulse modulation and the required topology criteria enable bit times of 6 µs and,
in turn, a gross transmission rate of 167 kbit/s to be achieved.

Radiated emissions:
Due to the narrow spectral bandwidth of sine2 pulse modulation used for AS-i and the
symmetrical design, radiated emissions from the AS-i system are minimal. Other devices are
not affected.
Noise immunity:
The symmetrical design and the coding method used (Manchester coding, APM (alternating
pulse modulation)) ensure that AS-i is highly immune to noise. In noisy industrial
environments, transmission errors are impossible to avoid. These are detected by the coding
procedure, however, and rejected as invalid. This means that the data made available to

An AS-i line can be up to 100 m long without additional components. Repeaters can be
used, however, to increase the length of the line. Two repeaters can be connected in series,
which can extend the network to 300 m (line structure). A separate AS-i power supply must

Figure 4-6 Network extension - now with AS-i extension plug, max. 200 m per segment
An extension plug can be used to double the length of an AS-i line to 200 m. Since repeaters
cannot be connected in series when they are used in conjunction with AS-i extension plugs,
this results in a maximum distance of 400 m between the master and slave and a maximum
cable extension of 600 m (master in the center of the network). Repeaters can be connected
in parallel in a star configuration each with up to 200 m long segments.
Figure 4-7 Network extension - now with AS-i extension plug, max. 200 m per segment, only one repeater connected in
series
The network can be extended even further if additional network components are used. An
extender can increase the length of the AS-Interface cable by 100 m. When this is used,
however, the first subline must not contain any slaves.

4.4 Application layer
4.4.1 AS-Interface module parameters
When the system is started up, the master sends parameters to each slave in order to define
its physical properties. The parameters are stored temporarily in the slave. The slave sends
a parameter echo, which means that is ready to exchange data with the master.
Parameter bits
Parameter bits are usually called "parameters" for short. These parameters can be used to
set the properties of the slaves (e.g. the signal range for A/B slaves, 0-20 mA or 4-20 mA). A
parameter set comprising 4 parameter bits (default value: 1111bin) is defined for each slave
in the master. The properties of most digital slaves are predefined and cannot be changed.
The default value is usually sent for these slaves. With A/B slaves, only 3 bits are available
because the highest bit is used for determining the address.
To find out which parameter bits can be used to set which slave properties, see the
operating instructions issued by the slave manufacturer.
In the SIMATIC system, you can set the slave properties in plain text via HW Config for all
the current masters. The parameter bits are then set accordingly by the system. This means
that you do not have to refer to the parameter lists in the operating instructions.
Configured parameters / permanent parameters
The parameter sets defined in the master are stored in a permanent memory in the master,
that is, the parameter bits are not lost when the master is switched off.
Current parameters / parameter image
When the master is switched on or once Profibus/Profinet communication has begun (e.g.
insert/remove plug or download the HW Config data to the station), the parameter bits are
copied from the permanent memory to a volatile memory in the master. These are then
transferred to the individual slaves.
When the master is switched on, each slave automatically receives the current parameter
bits from the master. These are then stored in a volatile memory, that is, these values are
lost in the event of a power failure.
Parameter bits cannot be read from the slave. In the parameter image, the master stores the
values that were last written to the slaves.
Note
If parameters are sent to the slave by means of the addressing unit, the slave "forgets" these
parameters as soon as it is disconnected from the addressing unit. The parameters active in
the slave are always defined by the connected AS-i master.
Operating principle
4.4 Application layer
AS-Interface system
70 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Parameter echo
If the master sends parameter bits to the slave, the slave responds with a parameter echo.
The parameter echo is a block of 4 bits in each slave, but it cannot be read directly. In
principle, it is completely independent of the parameter bit values that are sent. The master
saves the parameter echo to a volatile memory. Once the parameter echo has been sent,
the slave begins exchanging data cyclically. If a slave fails, the master sets the parameter
echo, which is stored internally, to the default value 1111 bin.
Parameter string
Only special AS-i slaves (with the slave profile 7.2 or 7.4) contain the parameter string.
No AS-i slaves from Siemens currently use this parameter string.
The parameter string is stored in the slave permanently (non-volatile) and can be written or
read. It comprises several parameter bytes with a length of up to 220 bytes. For more
information about the parameter string, see the operating instructions issued by the slave
manufacturer.
Data cannot be exchanged cyclically when the parameter string is being transferred from the
master to the slave (or vice versa). For this reason, the system must be switched to
parameter string exchange mode. The parameter bits and parameter echoes which, as a
result, are not actually available to users, are required for this purpose.

ASI_3422 command interface
This function block can be used to transfer changes from the PLC to the permanent memory
in the master and read them back to the PLC.
The FC can be adapted for non-SIMATIC systems (see the instructions in the link description
provided by the manufacturer).
You can download the FC function block "ASI_3422" from the following address:
www.siemens.de/automation/service&support
Commands available in the ASI_3422 command interface
Call
00hex Writes the parameters for an individual slave to the permanent memory.
This does not affect the parameter image.
No data is forwarded to the slave.
01hex Reads the parameters for an individual slave from the permanent memory.
Independent of the content of the parameter image and status of the slave.
39hex Reads the complete configuration of the AS-i bus, including all the current parameters from the
parameter images of all the slaves.
19hex Same as call 39hex, but for older masters (without A/B slaves, spec. 2.0)
3Ahex Writes the complete configuration of the AS-i bus to the master, that is, parameters are overwritten in the
permanent memory and copied automatically to the parameter image, which is then forwarded
automatically to the slaves.
This call performs a full reset on the AS-i bus, that is, all the slaves are momentarily "switched off" and
then restart cyclic data exchange.
1Ahex Same as call 3Ahex, but for older masters (without A/B slaves, spec. 2.0)
Note
With more recent masters, this call is executed in both configuration mode and protected
mode.
With older masters, this call is only executed in configuration mode, that is, the master may
have to be switched from protected mode to configuration mode (e.g. via call 0Chex - set
operating mode).
3Chex Writes the current parameters for all slaves to the parameter image.
This does not affect the permanent memory.
The master only transfers the parameters whose values have changed vis-à-vis the previous parameter
image to the slaves (i.e. slaves whose parameters have not changed do not send a parameter echo to
the master).
1Chex Same as call 3Chex, but for older masters (without A/B slaves, spec. 2.0)

the user.
04hex Copies the parameter image to the permanent memory.
4.4.3 Setting parameters via the display/WBM
DP/AS-i Link Advanced and IE/AS-i Link PN IO offer a range of functions via WBM that can
be used via an Internet browser.
A Java script is required for this purpose, which is stored in the links and loaded by the
browser.
Prerequisites
An IP address with a suitable subnet screen form must be set in the link (DP/AS-i Link
Advanced or IE/AS-i Link PN IO).
To access the link via WBM, you need a PC with an Internet browser. We recommend
Microsoft Internet Explorer (as of version 6.0).
Java must be active in the browser so that the script can be executed.
The PC must be connected to the LAN connection of the link by means of a standard or
crossed Ethernet cable (autocrossing).
Note
In this configuration, the PC is not connected to the LAN (company network).
To enable both the LAN and link to be used at the same time, a second network card or a
USB Ethernet adapter are recommended.
If you require direct integration in the LAN, contact your network administrator.
Note
The browser must be set in such a way that whenever it accesses a page, it always
downloads the latest version from the server. In Internet Explorer, you can set this by
choosing Tools > Internet Options... > General and then "Settings..." under "Temporary
Internet files".

Version 3.0 62 62 31 62 × 8 = 496 62 × 8 = 496
5.3 Extensions of the AS-Interface specification 2.1
AS-Interface specification 2.1 enables the number of network nodes to be double from
31 to 62. The "advanced addressing" function can be used to split the 31 addresses
supported in an AS-Interface network.
If this function is used for all 31 slaves, this means that max. 62 nodes can be
implemented in an AS-Interface network. The A/B slaves can be equipped with a
maximum of four inputs and three outputs. Advanced addressing can be used for digital
slaves but not for analog slaves or safety-oriented slaves (ASIsafe).
AS-Interface specification V2.1 also features an integrated analog value transfer function.
Integrated here means that the AS-i master is responsible for compiling the analog values
over several AS-i cycles. This relieves the workload on the user program. Depending on
the master, the values can now be transferred to the PLC by means of a transfer call or
transferred to the process image. Analog values can be accessed here just as easily as
digital values. The integrated analog value transfer function can be used with analog
slaves that support profiles 7.3 and 7.4.
5.4 Extensions of the AS-Interface specification 3.0
AS-Interface specification 3.0 enables a maximum of 1000 digital inputs/outputs to be
connected (profile S-7.A.A: 8DI/8DO as A/B slave).
New profiles allow advanced addressing to be used for analog slaves too.
"Fast analog profiles" accelerate the speed at which analog values are transferred.
Flexible use of analog modules: resolution (12/14 bits) and single/double channel can be
set as required.
Asynchronous serial protocol 100 baud or 50 baud bidirectional.

masters that do not support specification 2.1.
The default sub-address of A/B slaves is "A".
The new masters to specification 3.0 support all the new slave profiles and are also
downward compatible.

6.1.1 Overview
AS-Interface master operating modes
Each AS-i master has two operating modes:
Configuration mode
Protected mode
Configuration mode
Configuration mode is used for commissioning an AS-i installation:
The AS-i master can exchange data with any AS-i slave connected to the AS-i cable
(except for the AS-i slave with address "0").
New AS-i slaves on the bus are immediately detected, activated, and included in cyclic
data exchange.
The AS-i master cannot issue any error messages to the PLC via the slaves.
If the AS-i master is operated in configuration mode when a plant is in production mode, all
the I/O data can be freely exchanged with the PLC, although any fault messages are
suppressed.
Protected mode
In protected mode, the AS-i master only exchanges data with the configured AS-i slaves.
If any discrepancies between the target and actual configuration are identified, the AS-i
master can output a fault message to the PLC automatically.
Potential discrepancies:
The AS-i slave is configured but is either not available or defective.
The AS-i slave is configured but the wrong AS-i slave type has been connected.
The AS-i slave has not been configured but is available on the bus.

6.1.2.1 Overview
Master connection for CPUs 22x for the state-of-the-art SIMATIC S7-200 generation
The CP 243-2 is the AS-Interface master for the state-of-the-art SIMATIC S7-200
generation. The communications processor (6GK1 243-2AX01-0AX0) supports the extended
AS-Interface specification V2.1 and offers the following functions:
Supports up to 62 AS-Interface slaves and features an integrated analog value transfer
function (in accordance with the extended AS-Interface specification V2.1)
Supports all the AS-Interface master functions in accordance with the extended
AS-Interface specification V2.1.
Displays indicating the operating state and LEDs on the front plate indicating the
operational readiness of the connected slaves.
Fault indications (including AS-Interface voltage errors, configuration errors) by means of
LEDs on the front plate.
Compact housing in keeping with the design of the state-of-the-art SIMATIC S7-200
generation.
Benefits
SIMATIC S7-200 offers greater flexibility and a wider range of applications thanks to the
increased number of
Available digital and analog inputs/outputs
Commissioning times reduced thanks to the simple configuration process at the touch of
a button.
The LED displays help reduce downtime and service times in the event of a fault.
CP status
All the connected slaves and their operational readiness are displayed.
The AS-Interface supply voltage is monitored.
Scope of application
The CP 243-2 is the AS-Interface master connection and is designed exclusively for the
CPUs 22x of the state-of-the-art SIMATIC S7-200 generation. The AS-Interface dramatically
increases the number of available digital inputs and outputs for S7-200 (max. 248 DI /
186 DO for each CP).
Integrated analog value processing also means that analog values (max. 31 analog slaves
for each CP, each with up to 4 channels) are also available on the AS-Interface for the
S7-200. Up to two 243-2 CPs can be operated on the S7-200 simultaneously.

System Manual, 11/2008, 3RK2703-3BB02-1AA1 85
Structure
The CP 243-2 is connected to the S7-200 in the same way as an expansion module. It is
equipped with:
Two terminal connections for connecting the AS-Interface cable directly.
LEDs on the front plate for indicating the operating state and operational readiness of all
the connected and activated slaves.
Two pushbuttons for indicating the status information of the slaves, switching the
operating state, and adopting the existing actual configuration as a target configuration.
Function
The CP 243-2 supports all the functions defined in the extended AS-Interface specification
V2.1, which means that dual address assignments (A-B) allow up to 62 digital or 31 analog
slaves to be operated on the AS-Interface.
Thanks to integrated analog value processing, the analog values can be accessed just as
easily as digital values.
In the process image for the S7-200, the CP 243-2 is assigned one digital input byte (status
byte), one digital output byte (control byte), and eight analog input words and 8 analog
output words. As a result, the CP 243-2 occupies two slots. The status and control byte can
be used to set the operating mode of the CP 243-2 via the user program.
Depending on the operating mode, the CP 243-2 defines the I/O data for the AS-Interface
slave or diagnostic values, or enables master calls (e.g. re-addressing the slaves) in the
analog address space of the S7-200.
Configuration
All the connected AS-Interface slaves can be configured at the touch of a button. No further
configuration settings need to be made for the CP.

the front flap:
Two connections to the AS-i cable (bridged internally)
One connection for functional ground
The two connections for AS-i cables are bridged internally in the CP 243-2, which means
that the CP 243-2 can be "looped in" to the AS-i cable.
CAUTION
The load-carrying capacity of the AS-i connection contacts is max. 3 A. If this value is
exceeded on the AS-i cable, the CP 243-2 must not be "looped in" to the AS-i cable but
must instead be connected via a spur line (only one connection occupied on the CP 243-2).
The CP 243-2 must be connected to the protective conductor via the ground terminal.

Switching display statuses – DISPLAY pushbutton
You can switch between the status display (default setting) and the slave display using the
DISPLAY pushbutton. When you press the pushbutton repeatedly, the system switches to
the next display status and then finally back to the original status.
In the slave display, you can see the slaves on the AS-Interface. Five slaves are displayed
simultaneously. To switch to the next group of five slaves, press DISPLAY. The standard or
A slaves are displayed first followed by the B slaves (the "B" LED lights up).
The system switches back to the status display in the following cases:
Once the final group has been displayed (slave 30B, 31B) and you press DISPLAY
If you do not press DISPLAY for a long period (approx. 8 minutes)
Meaning of the LEDs
Two rows of LEDs are located on the front of the CP 243-2.
The LEDs CM, AUP, CER, APF, PWR, and SF in the top row represent the status
display.
The "B" LED indicates the B slaves. When the slave display is active, this LED also lights
up when B slaves are displayed.
The first five LEDs in the bottom row indicate the connected slaves (slave display).
The remaining three LEDs indicate the slave group.
The meaning of the LEDs depends on the status of the group displays.
If none of the LEDs in the group display is lit, this means that the status display is active
(i.e. the LEDs CM, AUP, CER, APF, PWR, and SF show the status of the CP 243–2).
If at least one of the LEDs in the group display is lit, the system switches to the slave display
(exception: the "PWR" LED is lit).
SET button
The SET button is required for configuring the CP 243-2.

easier to replace a defective AS-i slave on the AS-i cable. For more information
about this, see the manual "CP 243-2 AS-Interface Master".
CER Yellow Configuration
error
This LED indicates whether the slave configuration detected on the AS-i cable
matches the target configuration (LPS) in the CP 243-2. If any discrepancies are
detected, the CER LED lights up.
The CER LED lights up in the following cases:
If a configured AS-i slave is not detected on the AS-i cable (e.g. the slave has
failed).
If an AS-i slave that has not yet been configured is detected on the AS-i cable.
If a connected AS-i slave has different configuration data (I/O configuration ID
code, extended ID1 code, extended ID2 code) to the AS-i slave configured in the
CP 243-2.
When the CP 243-2 is in the offline phase
APF Red AS-i power
failure
Indicates that the voltage from the AS-i power supply unit on the AS-i cable is too low
or has failed.
PWR Green Power The PWR LED (power) indicates that the CP 243-2 is supplied with power.
SF Red System error This LED lights up in the following cases:
The CP 243-2 detects an internal error (e.g. EEPROM defective).

Slave display
To switch to the slave display, press the DISPLAY pushbutton. You can also switch from
group to group by pressing DISPLAY. The slave display is active when at least one group
LED is lit.
The slave display has the following properties:
If the CP 243–2 is in configuration mode, all the detected AS-i slaves are displayed.
If the CP 243–2 is in protected mode, all the active AS-i slaves are displayed. In protected
mode, the relevant LED starts flashing if AS-i slaves have either failed or if they have
been detected but not configured.
Details of the display statuses
The AS-i slaves are displayed in groups of five. The three group LEDs indicate (binary
coded) which group of five is being displayed. The five LEDs in the slave display then
indicate the detected or active AS-i slaves within this group.
To determine which slaves are active, find the group (row) in which the boxes equate to the
group LEDs that are lit. The LEDs in the slave display that are currently lit indicate which
slaves within this group are currently active.
If a group of B slaves is displayed, the "B" LED also lights up.

6.1.3 CP 343-2, CP 343-2 P
6.1.3.1 Overview
Difference between the CP 343-2 and CP 343-2 P
The functions supported by the two device types CP 343-2 and CP 343-2 P are largely the
same. The CP 343-2 P, however, features additional configuration options in STEP 7.
For this reason, the CP 343-2 P module must not be considered as a replacement for the
CP 343-2, which will continue to be available.
In the following description, a distinction is only made between the types when different
performance features are described. Unless otherwise indicated, this information provided
for CP 343-2 applies to both device types.
Master connection for SIMATIC S7-300 and ET 200M
The CP 343-2 is the AS-Interface master for SIMATIC S7-300 programmable logic controller
and the distributed I/O device ET 200M. The communications processor offers the following
functions:
Supports up to 62 AS-Interface slaves and features an integrated analog value transfer
function (in accordance with the extended AS-Interface specification V2.1)
Supports all the AS-Interface master functions in accordance with the extended
AS-Interface specification V2.1.
Displays indicating the operating state and LEDs on the front plate indicating the
operational readiness of the connected slaves.
Fault indications (including AS-Interface voltage errors, configuration errors) by means of
LEDs on the front plate.
Compact housing in keeping with the design of the SIMATIC S7-300.
CP 343-2 P only: supports the configuration of the AS-Interface network with STEP 7 as
of V5.2.
Benefits
Commissioning times reduced thanks to the simple configuration process at the touch of
a button.
Flexible, distributed structures can be created when the device is implemented in the DP
slave ET 200M.
The LED displays help reduce downtime and service times in the event of a fault:
Status of the AS-Interface network
Connected slaves and their operational readiness
The AS-Interface supply voltage is monitored.
Cuts the cost of storage and spare parts storage because the CP can be used for both
the SIMATIC S7-300 and ET 200M.
With the option of connecting 62 slaves along with integrated analog value processing,
this device is suitable even for complex applications.
Master
6.1 SIMATIC integrated masters
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 93
CP 343-2 P only: improved system documentation and support during servicing because
the AS-Interface configuration is documented in the STEP 7 project.
Scope of application
The CP 343-2 is the AS-Interface master connection for SIMATIC S7-300 and ET 200M. The
connection to the AS-Interface permits a maximum of 248 DI/186 DO to be accessed for
each CP.
Integrated analog value processing also allows simple analog signals (max. 31 analog
slaves for each CP, each with up to 4 channels) to be evaluated.
The CP 343-2 functionality is identical to that of the CP 343-2 P, which means that an old S7
application program can be used without any restrictions with the new CP. The AS-Interface
configuration can also be downloaded/uploaded with the STEP 7 hardware configuration.
Features
The CP 343-2 is connected to the S7-300 in the same way as an expansion module. It is
equipped with:
Two terminal connections for connecting the AS-Interface cable directly.
LEDs on the front plate for indicating the operating state and operational readiness of all
the connected and activated slaves.
Pushbuttons for indicating the status information of the slaves, switching the operating
state, and adopting the existing actual configuration as a target configuration.
Function
The CP 343-2 supports all the functions specified in the extended AS-Interface specification
V2.1, which means that dual address assignments (A-B) allow up to 62 digital or 31 analog
slaves to be operated on the AS-Interface. Integrated analog value processing provides easy
access to the analog values.
In I/O mode, the CP 343-2 is assigned 16 bytes in the analog address space of the SIMATIC
S7-300. The I/O data for the standard and A slaves is stored in this area. You can access
the binary values of B slaves in the user program using the system function blocks SFC 58
"write_data_record" / SFC 59 "read_data_record" with data record number 150.
A and B slaves comply with the extended AS-Interface specification V2.1. A function call
(FC) for the AS-Interface master calls (e.g. write parameters, read diagnostic values) is
available on the disk provided with the manual.
Configuration
All the connected AS-Interface slaves can be configured at the touch of a button. No further
configuration settings need to be made for the CP.
The CP 343-2 P supports configuration of the AS-Interface network with STEP 7 as of V5.2.

Figure 6-7 Transition from the PROFIBUS DP to the AS-Interface via DP/AS-Interface Link 20E
Scope of application
DP/AS-Interface Link 20E is a PROFIBUS DP slave (to EN 50 170) and AS-Interface master
(to EN 50 295) and enables the AS-Interface to be operated on the PROFIBUS DP.
Simple PROFIBUS masters can exchange I/O data with the AS-Interface cyclically. Masters
with acyclic services can exchange I/O data and carry out master calls. DP/AS-Interface Link
20E cannot be used in conjunction with the extender.
Design
Compact housing with degree of protection IP20 for mounting on DIN rails.
LEDs on the front plate for indicating the operating state and operational readiness of all
the connected and activated slaves.
The PROFIBUS DP address can be set at the touch of a button.
LED for the PROFIBUS DP slave address, DP bus error, and diagnosis.
Two buttons for switching the operating state and adopting the existing actual
configuration as the target configuration.
The power is supplied via the AS-Interface shaped cable.
Master
6.2 Routers
AS-Interface system
102 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Function
DP/AS-Interface Link 20E enables a DP master to access all the slaves in an AS-Interface
segment. In accordance with extended specification (V2.1), up to 62 slaves each with four
inputs and three outputs can now be connected.
DP/AS-Interface Link 20E is normally assigned 32 bytes of input data and 32 bytes of output
data in the DP master in which the I/O data for the connected AS-Interface slaves is stored.
The input/output buffer can be compressed so that only the required memory in the
DP master is used.
PROFIBUS DP masters can also trigger AS-Interface master calls via the acyclic PROFIBUS
services (e.g. write parameters, change addresses, read diagnostic values).
Configuration
DP/AS-Interface Link 20E can be configured on the PROFIBUS with STEP 7 or
COM PROFIBUS.
The type and GSD files are also supplied with the manual, which means that configuration
can also be carried out with STEP 7 versions in which DP/AS-Interface Link 20E is not yet

Two connections to the AS-i cable (jumpered internally)
One connection for functional ground
One connection to PROFIBUS (9-pin SUB D socket)
The connections are located under the top cover on the front panel of DP/AS-i Link 20E.
Connections to the AS-i cable
DP/AS-i Link 20E has two connections (jumpered internally in DP/AS-i Link 20E) for AS-i
cables.
This allows DP/AS-i Link 20E to be "looped in" to the AS-i cable.
CAUTION
Maximum load-carrying capacity
The maximum load-carrying capacity of the AS-i connection contacts is 3 A. If this value is
exceeded on the AS-i cable, DP/AS-i Link 20E must not be "looped in" to the AS-i cable but
must instead be connected via a spur line (one connection pair only occupied by DP/AS-i
Link 20E).
DP/AS-i Link 20E is supplied with power entirely from the AS-Interface.
The current consumption from the AS-Interface is 200 mA.

Status display
When DP/AS-Interface Link 20E is in the initial state (e.g. once it has been switched on), you
can read its status information from the LEDs (the three LEDs in the group display do not
light up green and the ADR LED does not light up at all).
LED Color Status Meaning
BF Red Bus failure Indicates a fault on PROFIBUS DP.
This LED lights up in the following cases:
The connection between the DP master and DP/AS-i Link 20E
is interrupted or the DP master is not active.
DP/AS-i Link 20E has been incorrectly
configured/parameterized by the DP master.
SF Red System error This LED lights up in the following cases:
In protected mode: a diagnostic alarm (incoming) was
triggered in the DP master.
DP/AS-i Link 20E detects an internal fault (e.g. EEPROM is
defective).
DP/AS-i Link 20E cannot currently execute the required mode
switchover when the SET button is pressed (e.g. a slave exists
with the address 0).
PWR Green Run This LED lights up when DP/AS-Interface Link 20E is supplied
with power.
APF Red AS-i power failure Indicates that the voltage supplied by the AS-i power supply unit
via the AS-i cable is too low.
Note:
DP/AS-Interface Link 20E is supplied with power entirely from the
AS-Interface. This means that if the AS-i voltage fails completely,
this cannot be indicated by "AS-i power failure". You can identify
this status when the "PWR" LED is not lit up.
CER Yellow Configuration error This LED indicates whether the slave configuration detected on
the AS-i cable matches the target configuration in DP/AS-i Link
20E. If not, the CER LED lights up.
The CER LED lights up in the following cases:
If a configured AS-i slave is not detected on the AS-i cable
(e.g. the slave has failed).
If an AS-i slave that has not yet been configured is detected on
the AS-i cable.
If a connected AS-i slave has different configuration data (I/O
configuration, ID code) to the AS-i slave configured in DP/AS-i
Link 20E.
When DP/AS-i Link 20E is in offline mode.
AUP Green Autoprog available When DP/AS-i Link 20E is in protected mode, this LED indicates
that the address of an AS-i slave can be programmed
automatically. Automatic address programming makes it easier to
replace a defective AS-i slave on the AS-i cable.
CM Yellow Configuration mode This display indicates the DP/AS-i Link 20E operating mode.
Display ON: Configuration mode
Display OFF: Protected mode
Configuration mode is only required for commissioning DP/AS-i
Link 20E. In configuration mode, DP/AS-i Link 20E activates all
the connected AS-i slaves and exchanges data with them.

Slave display for AS-i slaves
To switch from the status display for the master to the status display for the slaves, press the
DISPLAY button.
The AS-i slaves are displayed in groups of five. The top three group LEDs indicate which
group of five is displayed by lighting up green. A further distinction is made between:
Static: AS-i standard slaves and A slaves
Flashing: B slaves
The LEDs below light up green to indicate which AS-i slaves within the group have been
detected or are active.
To switch from group to group, press the DISPLAY button.
The system switches back to the status display in the following cases:
Once the last group has been displayed (AS-i slave 30, 31) and when you press the
DISPLAY button twice (i.e. switch to the PROFIBUS address display and then to the
status display).
If the DISPLAY button is not pressed for approx. 8 minutes.
Characteristics of the slave display
If DP/AS-i Link 20E is in configuration mode, all the detected AS-i slaves are displayed.
If DP/AS-i Link 20E is in protected mode, all the active AS-i slaves are displayed. In
protected mode, the relevant LED starts flashing if AS-i slaves have either failed or if they
have been detected but not configured.

Figure 6-10 Example: slave display on DP/AS-i Link 20E
In the above image, you can see the following:
The group LEDs select the second group of five.
Within this group, the 5 LEDs at the bottom indicate the active AS-i slaves 6 and 8.
Displaying and setting the PROFIBUS address
If the top LED in the group display (ADR) is red, the 7 LEDs below this indicate the
PROFIBUS address of DP/AS-i Link 20E in binary form.
To set the PROFIBUS address of DP/AS-i Link 20E, carry out the following steps:
1. Disconnect the DP master (e.g. unplug the PROFIBUS connector or switch the DP
master to STOP).
Note
The PROFIBUS address can only be set in this operating state.
2. Switch the DP/AS-i Link 20E display by pressing the DISPLAY button repeatedly until the
ADR LED lights up red. (Note: from the status display, you have to press the button
15 times.)
DP/AS-i Link 20E indicates the current PROFIBUS address with the seven LEDs at the
bottom.
3. When you press the DISPLAY button, DP/AS-i Link 20E returns to the status display and
the set PROFIBUS address is retained.
If you press the SET button, however, you can reset the PROFIBUS address. When the
BF LED flashes, this indicates the most significant bit in the PROFIBUS address.
4. When you press SET, this bit is set (LED on); when you press DISPLAY, however, the bit
is reset (LED off). The display then switches to the SF LED (next address bit in the
PROFIBUS address).
5. Using the same procedure as described in the previous step, you can now set/reset the
individual bits in the PROFIBUS address one after the other.
Master
6.2 Routers
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 109
6. When all the bits have been entered, the display for the set address bits switches rapidly
from red to green or yellow to green (flashing). When you press SET again, the set
PROFIBUS address is adopted by DP/AS-i Link 20E. If you press DISPLAY, however, the
new address is rejected. You now have to enter the new address again (see steps 4
and 5).
The significance of the address bits in the PROFIBUS address indicated by the LEDs is
explained in the following example:

6.2.2 DP/AS-i LINK Advanced
6.2.2.1 Overview
Data exchange between AS-Interface and PROFIBUS DP
Compact router between PROFIBUS (DP slave) and AS-Interface.
Single and double AS-Interface master (to AS-Interface Specification V3.0) for connecting
62 AS-Interface slaves in each case and integrated analog value transmission.
Integrated, high-performance ground-fault monitoring for the AS-Interface cable.
User-friendly on-site diagnosis and commissioning functions via a graphical display and
controls or via a Web interface with a standard browser.
Optimum TIA integration via STEP 7, integration in engineering tools from third-party
vendors via the PROFIBUS type file (GSD).
Vertical integration (standard Web interface) via Industrial Ethernet.
Power supplied via the AS-Interface cable or with 24 V DC (optional).
Modules can be exchanged without the PG by means of C-PLUG (optional).
Benefits
Quick PLC-independent commissioning by means of simple configuration at the touch of
a button and testing the AS-Interface line via the display or WBM. (Page 72)
User-friendly diagnosis via the display or Web interface and easy replacement of
modules by means of the exchange medium C-PLUG helps reduce downtime and service
times if a slave fails.
Reduced installation costs because the power is supplied entirely via the AS-Interface
cable, which means that no additional power supply is required.
Reduced engineering overhead through convenient configuration of Siemens slaves per
slave catalog in HW-Config (STEP 7)
Lower costs for high quantity frameworks as result of the dual AS-Interface master
Scope of application
DP/AS-i LINK Advanced is a PROFIBUS DPV1 slave (to EN 50 170) and AS-Interface
master (in accordance with AS-Interface Specification V3.0 to EN 50 295) and enables
transparent data access to the AS-Interface from PROFIBUS DP.
PROFIBUS DP masters can exchange I/O data with the AS-Interface cyclically. DP masters
with acyclic services can also carry out AS-Interface master calls. DP/AS-i LINK Advanced
is, therefore, suitable for distributed configurations and for integrating a lower-level
AS-Interface network.
The AS-Interface single master version of DP/AS-i LINK Advanced is suitable for
applications with typical volumes of data.

Function
DP/AS-i LINK Advanced provides the PROFIBUS DP master with cyclic access to the
I/O data for all slaves in a lower-level AS-Interface segment. According to the extended
AS-Interface Specification (V3.0), up to 62 slaves each with four inputs and four outputs (or
eight inputs and eight outputs) as well as analog slaves on each AS-Interface line can be
connected.
In the DP master, DP/AS-i LINK Advanced is normally assigned 62 input and 62 output bytes
in which the I/O data for the connected digital AS-Interface slaves is stored. The input/output
buffer can be compressed so that only the required I/O memory in the DP master system is
used. The integrated function for analyzing analog signals is just as simple to use as the
function for accessing digital values, which means that communication modules no longer
have to be called up.
PROFIBUS DP V1 masters can also trigger AS-Interface master calls via the acyclic
PROFIBUS services (e.g.: write parameters, change addresses, read diagnostic values).
An operator display in AS-i Link allows you to commission the lower-level AS-Interface line.
DP/AS-i LINK Advanced is equipped with an additional Ethernet port that allows you to
leverage the benefits of the integrated Web server, thereby making it even easier to use the
operator display. The firmware can also be upgraded free of charge.
The optional C-PLUG allows you to replace modules without a PG, thereby minimizing
downtime if a fault occurs.
Diagnostics
A comprehensive range of diagnostic functions are available via LEDs, displays, controls, a
Web interface, or STEP 7. These include:
Operating state of the link
State of the link as a PROFIBUS DP slave
Diagnosis of the AS-Interface network
Telegram statistics

Connections
DP/AS-INTERFACE LINK Advanced features the following connections:
Two separate connections to the AS-i cable (with double master)
One connection for an alternative 24 V DC power supply (optional) and functional ground
One connection to PROFIBUS (9-pin SUB D socket)
One LAN connection (RJ45) (can be assigned optionally)
Connections to the AS-i cable(s) and power supply
DP/AS-INTERFACE LINK Advanced has two connections for AS-i cables (lines 1 and 2).
They are each connected via a 4-pin connector each with two + and two - terminals
(jumpered internally).
This allows DP/AS-INTERFACE LINK Advanced to be "looped in" to the AS-i cable.
CAUTION
Maximum load-carrying capacity
The maximum load-carrying capacity of the AS-i connection contacts is 3 A. If this value is
exceeded on the AS-i cable, DP/AS-INTERFACE LINK Advanced must not be "looped in"
to the AS-i cable but must instead be connected via a spur line (one connection pair only
occupied by DP/AS-INTERFACE LINK Advanced).
DP/AS-INTERFACE LINK Advanced can receive its entire power supply from the
AS-Interface (AS-i line 1 only). The current consumption from the AS-Interface here is
250 mA at 30 V.

6.2.3 DP/AS-i F-Link
6.2.3.1 Overview
Link between PROFIsafe and ASIsafe
Compact, safety-oriented router between the PROFIBUS (DP slave) and AS-Interface.
Monitors the inputs of safety-oriented binary AS-i slaves (ASIsafe slaves) and forwards
data via PROFIsafe. No need for additional safety-oriented components for AS-Interface
(e.g. additional cables, safety monitor).
AS-i master in accordance with AS-Interface Specification V3.0, master profile M4, for
connecting up to 62 AS-i slaves and integrated analog value transmission.
Direct integration in PROFIBUS networks. Integration in PROFINET environments via the
PROFINET/PROFIBUS gateway (IE/PB Link) or via SIMATIC S7-315 F PN/DP,
S7-317 F PN/DP, or S7-416F-3 PN/DP.
Optimum TIA integration in STEP 7 via Object Manager, integration in engineering tools
from third-party vendors via the PROFIBUS type file (GSD).
Local diagnosis via LEDs and display with operator input keys.
Module exchange without PG because startup data is transferred via the PROFIBUS DP
master.
Benefits
Gaps in (bus-based) safety technology closed: safety-oriented signals (EMERGENCY
STOP, door tumbler, light curtains etc.) collected with AS-i and transferred to higher-level
F PLC. This enables:
Quick installation, easy commissioning: benefits of AS-i can now be systematically
leveraged in the field for Safety Integrated.
Cost-effective solution because ASIsafe is ideally suited for collecting "fewer but
distributed failsafe bits".
Price benefit: as a fully-fledged AS-i master in accordance with Specification V3.0, large
volumes of project data can be processed in the AS-i network (496 inputs and outputs in
each case, up to 62 analog slaves).
Long-term investment security:
Integration in PROFIBUS networks as with DP/AS-i Links Advanced or 20E
Backward compatibility to spec. V2
Open for state-of-the-art automation concepts with AS-i
Quick commissioning with simple configuration at the touch of a button (code sequences
of ASIsafe slaves can also be taught in at the touch of a button).
User-friendly configuration of all Siemens slaves via the slave catalog in HW Config
(STEP 7) helps reduce engineering work, especially for the ASIsafe slaves modeled on
PROFIsafe slaves.

Safety logic programming with the familiar, powerful commands of the Distributed Safety
package from the failsafe SIMATIC PLC in F-FUP or F-FOP (incl. TÜV-certified function
blocks for standard safety applications) helps cut costs.
Can also be used in machine tools with SINUMERIK 840 D SL in conjunction with the
Profibus type file (GSD).
User-friendly diagnosis via the display and easy replacement of modules (only a few
settings need to be made via the operator input keys; configuration tool not required) help
reduce downtime and service times.

Scope of application
DP/AS-i F-Link is a PROFIBUS DP-V1 slave (to EN 50170) and AS-i master (in accordance
with AS-Interface Specification V3.0 to EN 50295) and enables transparent data access to
AS-Interface from the PROFIBUS DP. DP/AS-i F-Link is also the only AS-i master with which
safety-oriented input data can be transferred from ASIsafe slaves to a failsafe CPU with the
PROFIBUS DP master via the PROFIsafe protocol. Additional safety-oriented cabling or
monitoring is not required (in particular, no AS-Interface safety monitor is required).
Depending on the slave type, binary or analog values can be transferred. All slaves that
comply with AS-Interface Specification V3.0 can be operated as AS-i slaves.
PROFIBUS DP masters to DP-V0 or DP-V1 can exchange I/O data with lower-level AS-i
slaves cyclically. PROFIBUS DP masters with acyclic services to DP-V1 can also carry out
AS-i master calls (parameters, diagnosis). In addition to the digital I/O data, analog data is
also stored in a high-performance memory in the cyclic I/O area (during configuration with
Master
6.2 Routers
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 127
Object Manager in STEP 7) of a failsafe S7-300/416 F-CPU (communication modules do not
need to be called separately).
In configuration mode, DP/AS-i F-Link reads the configuration data of the I/O devices on the
AS-Interface. Slave addresses can be set and code sequences of secure AS-i slaves taught
in via the display and operator input keys.
During operation, four LEDs and the display provide detailed diagnostic information which, if
necessary, can be used to localize faults immediately. A user program enables diagnosis
data sets to be read and made available to a higher-level operator control and monitoring
system (e.g. WinCC).
Design
Stable, tried-and-tested plastic housing with degree of protection IP20 for DIN rail or wall
mounting.
Compact design
Display on the front for indicating the operating state and operational readiness of all
the connected and activated AS-Interface slaves.
Two buttons on the front for commissioning and retrieving diagnostic data.
Four LEDs for indicating the operating state of the device, PROFIBUS DP, and the
AS-Interface network.
Front PROFIBUS DP connection with SUB D connector.
Removable terminal blocks for connecting the AS-i +/- and power supply (by 24 V DC
PELV power supply unit); low width (45 mm).
Simple installation on a DIN rail or on the wall.
Operation without fan or battery.
Rapid replacement of devices in the event of a fault.
Communications principle
The PROFIBUS DP master communicates with the AS-i slaves via DP/AS-i F-Link. The AS-i
communication objects are mapped to a contiguous data area for input and output data in
the PROFIBUS DP master. DP/AS-i F-Link manages two interfaces here:
Interface with the PROFIBUS DP master: PROFIBUS DP
Interface with the AS-i slaves: AS-Interface

6.2 Routers
AS-Interface system
128 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Configuration
DP/AS-i F-Link can be configured with STEP 7 as of version V5.4 SP1 or simply by copying
the actual configuration on the display.
Alternatively, DP/AS-i F-Link can be integrated by means of the PROFIBUS type file (GSD)
in the engineering tool.
When DP/AS-i F-Link is configured with STEP 7, the AS-Interface configuration can be
uploaded to STEP 7 as of V5.4 SP1.
Siemens AS-Interface slaves can also be easily configured in HW Config (slave catalog).
Programming
Unlike the AS-Interface safety monitor, DP/AS-i F-Link is simply a gateway with no separate
safety logic.
The safety function is programmed at the level of the higher-level failsafe DP master, e.g.:
With Distributed Safety as of version V5.4 SP1 for SIMATIC S7-300F/416F
With SAFETY INTEGRATED "SI-Basic" or "SI-COMFORT" NCU software for
SINUMERIK 840D SL.

6.2.4.1 Overview
Transparent data access to AS-Interface from Industrial Ethernet
Compact router between Industrial Ethernet (PROFINET IO device) and AS-Interface
Single and double AS-Interface master (to AS-Interface Specification V3.0) for connecting
62 AS-Interface slaves in each case and integrated analog value transfer
High-performance, integrated analog value transmission
Integrated ground-fault monitoring for the AS-Interface cable
User-friendly on-site diagnosis and commissioning functions via a graphical display and
controls or via a Web interface with a standard browser.
Optimum TIA integration via STEP 7, integration in engineering tools from third-party
vendors via the PROFINET type file (GSDML)
Vertical integration (standard Web interface (Page 72)) via Industrial Ethernet
Power supplied via the AS-Interface cable or with 24 V DC (optional).
Modules can be exchanged without the PG by means of C-PLUG (optional).
Benefits
Quick commissioning by means of simple configuration at the touch of a button and
testing the AS-Interface line via the display or Web interface.
User-friendly diagnosis via the display or Web interface help reduce downtime and
service times if a slave fails.
Reduced installation costs because the power is supplied entirely via the AS-Interface
cable, which means that no additional power supply is required.
User-friendly configuration of Siemens slaves by dragging/dropping them to HW Config
(STEP 7) helps reduce engineering work.
Scope of application
IE/AS-i LINK PN IO is a PROFINET IO device (to IEC 61158) and AS-Interface master (in
accordance with AS-Interface Specification V3.0 to EN 50 295) and enables transparent data
access to the AS-Interface from Industrial Ethernet.
PROFINET IO controllers can exchange I/O data with the AS-Interface cyclically. Acyclic
services also enable AS-i master calls to be carried out (parameters, diagnosis). IE/AS-i
LINK PN IO is, therefore, suitable for distributed configurations and for integrating a
lower-level AS-Interface network.
The AS-i single master version of IE/AS-i LINK PN IO is suitable for applications with typical
volumes of data.
Master
6.2 Routers
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 141
The AS-i double master version of IE/AS-i LINK PN IO is suitable for applications with large
volumes of data. In this case, the double data volumes can be processed on two separate
AS-i lines.

An upstream IWLAN client module (e.g. SCALANCE W746-1PRO) can be used for the
wireless integration of an AS-Interface line in the PROFINET environment. Examples of
applications here include those that were previously implemented with fault-prone ground
cables or contact conductors. This helps cut maintenance costs.

(not supplied).
Function
IE/AS-i LINK PN IO provides the PROFINET IO master with cyclic access to the I/O data for
all slaves in a lower-level AS-Interface segment. According to the extended AS-Interface
Specification (V3.0), up to 62 slaves each with four inputs and four outputs as well as analog
slaves on each AS-Interface line can be connected.
In the IO controller, IE/AS-i LINK PN IO is normally assigned 62 input and 62 output bytes in
which the I/O data for the connected AS-Interface slaves is stored. The input/output buffer
can be compressed so that only the required I/O memory in the IO controller system is used.
The integrated function for analyzing analog signals is just as simple to use as the function
for accessing digital values.
PROFINET IO controllers can also trigger AS-Interface master calls via the acyclic
PROFINET services (e.g.: write parameters, change addresses, read diagnostic values).
An operator display in AS-Interface Link allows you to commission the lower-level AS-i line.
IE/AS-i LINK PN IO is equipped with two switched Ethernet ports that allow you to leverage
the benefits of the integrated Web server, thereby making it even easier to use the operator
display. The firmware can also be upgraded.
The optional C-PLUG allows you to replace modules without a PG, thereby minimizing
downtime if a fault occurs.
Diagnostics
A comprehensive range of diagnostic functions are available via displays, controls, a Web
interface, or STEP 7. These include:
Operating state of the link
State of the link as a PROFINET IO device
Diagnosis of the AS-Interface network
Telegram statistics
Standard diagnosis pages for rapid access to diagnostic data by means of a standard
browser
Configuration
IE/AS-i LINK PN IO can be configured with STEP 7 as of version V5.4 SP2 or simply by
copying the actual configuration on the display.
Alternatively, IE/AS-i LINK IO can be integrated by means of the PROFINET type file (GSD)
in the engineering tool:
STEP 7 versions older than V5.5 SP2
Engineering tools from third-party vendors

6.2.4.3 Connection
Connections
IE/AS-i LINK features the following connections:
Two separate connections to the AS-i cable (with double master)
One connection for an alternative 24 V DC power supply (optional) and functional ground
Two LAN RJ45 connections as independent switch ports (one on PROFINET IO and one, for
example, for the WBM configuration)
Connections to the AS-i cable(s) and power supply
IE/AS-i LINK has two connections for AS-i cables (lines 1 and 2). They are each connected
via a 4-pin connector each with two + and two - terminals (jumpered internally).
This allows IE/AS-i LINK to be "looped in" to the AS-i cable.
CAUTION
Maximum load-carrying capacity
The maximum load-carrying capacity of the AS-i connection contacts is 3 A. If this value is
exceeded on the AS-i cable, IE/AS-INTERFACE LINK PN IO must not be "looped in" to the
AS-i cable but must instead be connected via a spur line (one connection pair only
occupied by IE/AS-i LINK).
IE/AS-i LINK can receive its entire power supply from the AS-Interface (AS-i line 1 only). The
current consumption from the AS-Interface here is 320 mA at 30 V.
Alternatively, IE/AS-i LINK can be supplied via a separate power supply unit (24 V DC).

Power supply units 7
7.1 Overview
Space-saving power supply units and data decoupling
AS-Interface power supply units are among the most important components of an
AS-Interface network. They supply the electronic network components (AS-Interface
modules and AS-Interface masters) as well as the connected sensors. Integrated data
decoupling in the AS-Interface power supply units ensure that data and energy are kept
separate but that AS-Interface can transfer data and energy along the same cable.
Benefits
Compact design saves space in the cabinet/field.
Increased output power allows additional AS-Interface nodes to be connected.
Integrated ground-fault and overload detection functions make the application more
reliable, which does away with the need for additional components.
Diagnostic memory, remote indication, and remote reset allow faults in the system to be
quickly detected, thereby reducing downtimes.
Spring-loaded connection system allow the devices to be installed quickly and securely.
Terminal blocks can be quickly replaced, thereby reducing downtimes.
The ultra-wide range input of the 8 A version allows single and dual-phase operation,
which means that a neutral conductor is not required.
UL/CSA ensures that the device can be used worldwide.

Figure 7-1 Basic structure of the AS-Interface power supply units
AS-Interface power supply units are primary-side regulated DC power supply units. The
primary switched-mode regulators generate a regulated DC voltage of 30 V DC with high
control stability and low residual ripple.
The AS-Interface two-wire cable transfers data and energy simultaneously. For this reason,
AS-Interface power supply units must ensure that the AS-Interface network is supplied with
power while the data is decoupled.
Standard power supply units are not suitable here, which is why standard power supply units
must not be used for supplying an AS-Interface network. AS-Interface power supply units
supply the network electronics (AS-Interface masters and AS-Interface modules) as well as
all the connected sensors. Graded power supply units from 2 to 8 A are available depending
on the power requirements of the AS-Interface network.
As shown in the block diagram, the new generation of AS-Interface power supply units
(3RX95...) with IP20 also features integrated ground-fault and overload detection.
Function: features of the latest generation of power supply units 3RX95..:
Compact design
Available in widths of 50/70/120 mm, the latest devices are among the most compact
AS-Interface power supply units available offering a very high degree of power density.
Thanks to the small surface area of these devices, other devices can be mounted on the
DIN rail next to the power supply unit. As a result, they can be installed directly next to
other devices (unlike other compact power supply units).
Power supply units
7.1 Overview
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 155
Increased power
The new devices have an output current of 3 / 5 / 8 A.
Integrated ground-fault detection
Ground-fault detection to EN 60204-1 is obligatory for AS-Interface. The new generation
of AS-Interface power supply units all feature integrated ground-fault detection that
reliably detects and reports ground faults. Additional contacts also allow users to
determine whether the AS-Interface voltage is to be switched off directly if a ground fault
occurs, thereby preventing the machines from starting unintentionally and, in turn,
preventing the system from being damaged if a fault occurs.
Remote reset and remote indication
The detected ground fault can be signaled and evaluated on a central controller via
brought-out signal contacts. The stored diagnostic data can be reset locally using the
reset button. It can also be reset, however, by a controller via a reset input.
Integrated overload detection
An output-side overload is detected and signaled via a diagnostics LED.
Diagnostic memory
A ground fault and output-side overload are stored in a diagnostic memory until the
system is reset and signaled via the appropriate LEDs. This makes it easier to diagnose
faults in an AS-Interface network because the service personnel can immediately identify
the potential source of system faults (even after a fault has occurred).
Diagnostic LEDs
The status of the AS-Interface power supply unit can be determined locally on the power
supply unit via three differently-colored LEDs:
Overload LED, red
Ground-fault detection LED, yellow
OK status LED, green (output voltage ≥ 26.5 V)
Ultra-wide range input with 8 A
The ultra-wide range input from 120 to 500 V with the 8 A variant means that the device
can be used in virtually any network in the world. In addition, this variant does not require
a neutral conductor because the device can be connected directly between 2 phases in a
network.
Removable terminal blocks with spring-loaded connection
The power supply unit is equipped with three terminal blocks: one block for the input side,
one for the output side, and one for the information terminals. These can be removed if
required, thereby enabling the power supply unit to be quickly and easily replaced if a
fault occurs. The spring-loaded connection system used for the terminals also enables
the cable strands to be quickly and securely connected.

8.1 Setting the AS-i address
AS-Interface system
164 System Manual, 11/2008, 3RK2703-3BB02-1AA1
8.1 Setting the AS-i address
Unique addressing
In the as-delivered condition, an I/O module (slave) has the address 0. It is detected by the
master as a new slave that has not yet been addressed and, in this condition, has not yet
been integrated in standard communication/data exchange.
To enable data to be exchanged between the master and slaves, you have to assign a
unique address for each slave (i.e. each slave address must be different) when
commissioning the AS-Interface network.
You can choose the addresses as required:
In address range 1 to 31, for slaves with standard addressing mode
In address range 1A to 31A and 1B to 31B, for slaves with extended addressing mode
(A/B slaves, as of AS-i Spec. 2.1)
Addresses can also be assigned once the devices have been installed.
Addressing the slaves
You can set the slave address in different ways:
Offline with the addressing unit via the addressing socket or at the AS-i connection.
Recommended when assigning addresses for the entire system. The direct connection
between the slave and addressing unit ensures that the slave modules are not mixed up.
Online by the AS-i master and in the PLC configuration software.
Recommended for assigning addresses to individual slaves if an addressing unit is not
available. Before assigning addresses, you must ensure that each address exists only
once in the AS-i network, that is, several new, additional modules (with address 0 in
as-delivered condition) must not be connected to the AS-i cable.
CAUTION
As soon as you have assigned a valid address, the master can start cyclic data
communication, that is, outputs can be set or inputs read that result in follow-up switching
operations. Make sure that the system does not enter a hazardous state (e.g. switch off the
AS-i voltage as a precaution).

8.4.1 Digital K60 input/output modules - panel IP67
8.4.1.1 Overview
Standard K60 compact modules
K60 compact modules with max. four digital inputs and four digital outputs.
These compact modules contain the communications electronics and the standard M12
connections for inputs and outputs. Up to four sensors and four actuators can be
connected to the compact module.
K60 compact modules with max. eight digital inputs and two digital outputs.
These modules have eight digital inputs with an M12 connector.
The module requires two AS-Interface addresses for processing all the inputs and
outputs. Addresses are assigned here using a double addressing socket.
K60 compact modules with four digital inputs and outputs in accordance with AS-i
Specification 3.0.
AS-i Specification 3.0 extends the AS-Interface bus system to include a range of new
features.
Extended address mode (A/B addresses) allows 62 nodes to be connected to an AS-i
network. This means that, even in the case of A/B slaves, four outputs can now be used
(instead of just three outputs as defined in Specification 2.1). In the maximum
configuration of an AS-i network, therefore, this means that 248 inputs and 248 outputs
are available.
Note, however, that these modules can only be operated with a new master in
accordance with AS-i Specification 3.0 (e.g. new DP/AS-i LINK Advanced or IE/AS-i LINK
PN IO) and that the cycle times for the outputs in this case can be a maximum of 20 ms.
K60 compact modules for use in potentially explosive areas (ATEX).
Two versions of the K60 modules are available for use in potentially explosive areas
(zone 22) in accordance with classification II 3D (dust in the air, non-conductive dust).
The version with four inputs and four outputs has the ID (Ex) II 3D T75 °C IP65X, the
version with four inputs has the ID (Ex) II 3D T60 °C IP65X.
Certain factors must be taken into account to ensure that these devices function safely
and reliably. In particular, suitable measures must be taken to protect the module against
mechanical damage. For further conditions for ensuring safe and reliable operation, see
Technical specifications (Page 178).
8.4.1.2 Connection
For information on connecting the AS-i bus and auxiliary voltage UAUX as well as the
actuators and sensors, see Connection (Page 166).

8.4.2 Digital input/output modules K60R - panel IP68 / IP69K
8.4.2.1 Overview
Modules with a degree of protection IP67 are not suitable for use in areas subject to
continuously high levels of humidity (e.g. when drilling emulsions, cutting oils, or
high-pressure cleaners are used). Instead, the K60R compact module with degree of
protection IP68/IP69K is the ideal solution here.
IP68/IP69K tests
The K60R modules are subject to the following tests:
More stringent test than IP67:
90 min at a depth of 1.8 m in water (IP67: 30 min at a depth of 1 m in water)
Salt water test:
immersed in salt water for five months, at a depth of 20 cm at room temperature
Test with oil highly prone to creep:
five months fully immersed in oil at room temperature
Test with drilling emulsion:
five months at room temperature (constituents of drilling emulsion: anionic and non-ionic
emulsifiers, paraffined, low-aroma mineral oil, boric acid alkanolamines, corrosion
inhibitors, oil content: 40 %)
Test in oil bath (oil: Excelence 416) with fluctuating temperature of the oil bath:
130 cycles at 15 to 55°C, two months
Cleaning with high-pressure cleaner to IP69K:
80 to 100 bar, distance of 10 to 15 cm, time per side > 30 sec, water temperature: 80°C
To simulate requirements as realistically as possible, the modules were artificially aged by
subjecting them to 15 temperature cycles at -25/+85°C prior to the tests. During the tests,
the modules were connected with 3RX1 connection cables. Unassigned connections were
sealed with screw caps (3RK1 901-1KA00).

AS-Interface system
188 System Manual, 11/2008, 3RK2703-3BB02-1AA1
In the IP67 environment, the standard components are connected by means of flat ribbon
cables. Spur lines are branched to the IP68 environment via an AS-Interface M12 branch
(3RK1901-1NR..). The module is connected by means of round cables with an M12 cable
plug. Instead of an addressing socket, the module is now equipped with an M12 bus
connection for this purpose. The AS-Interface bus cable and 24 V DC auxiliary voltage are
both routed in a 4-pole round cable, which must not contain a grounding conductor. The
ground connection is established via the mounting plate.
Only cables with integral M12 connectors can be used in the IP68 environment.
Prefabricated versions of these cables are available as M12 cable connectors/plugs:
3RX8000-0GF42-1AA6: 0.5 m long
3RX8000-0GF42-1AB0: 1.0 m long
3RX8000-0GF42-1AB5: 1.5 m long
The maximum length of the cable between the IP68 T-distributor and the module must not
exceed 1.5 m.
When longer cables are required to connect the distributor and K60R module, cables that
can be cut as required and have an M12 cable plug and open cable end can be used, fitted
with an M12 connector (straight: 3RX8000-0CD45; angle: 3RX8000-0CE45) and connected
to the distributor. Two different versions of this cable are available:
3RX8000-0CB42-1AF0: 5 m long, with M12 cable plug
3RX8000-0CC42-1AF0: 5 m long, with M12 angle cable plug
If more than one K60R module is to be connected to a spur line, they can be distributed
further by means of a T-distributor (3RK1901-1TR00) with degree of protection IP68.
The following general conditions must be taken into account:
The installation guidelines for AS-Interface must always be observed. The max.
permissible current for all M12 connection cables is restricted to 4 A. The cross-section of
these cables is only 0.34 mm². To connect the K60R modules, the M12 connection
cables mentioned above can be used for the spur lines. The voltage drop induced by the
ohmic resistance (approx. 0.11 Ω/m) must be taken into account.
The following maximum lengths apply to round cable connections whereby AS-i and UAUX
are routed in the same cable:
For each spur line from the branch to the module: max. 5 m
Total of round cable components in one AS-Interface network: max. 20 m
Note
Screw caps and M12 connections must be tightened with the correct torque.

8.4.3 K60 compact module data coupler - panel IP67
8.4.3.1 Overview
This module is equipped with two AS-i slaves that are connected to two different AS-i
networks. Each of the two integrated slaves has four virtual inputs and four virtual outputs.
This is the easiest and most cost-effective way of enabling the bidirectional transfer of four
data bits between two AS-i networks. The data coupler requires an address in each AS-i
network.
Depending on the number of nodes, each AS-i network functions with a different cycle time,
which means that the two AS-i networks are never synchronous. For this reason, only
standard data and not safety-oriented data (ASIsafe) can be transferred via the AS-i data
coupler.
The two AS-i networks are electrically isolated in the device.
The output bits from AS-i network 1 are read as input bits in AS-i network 2 (and vice versa).
The statuses of the outputs are indicated by LEDs.
NOTICE
Two AS-i networks must not be electrically connected.

8.4.4 Digital K45 input/output modules - field IP67
8.4.4.1 Overview
The range of 'large' K60 compact modules now includes the K45 compact module series
to extend the lower end of the product range.
The K45 modules, which are significantly smaller, offer all the existing benefits of the K60
compact modules. They have the same surface area as the user modules. The installation
depth, however, is just 2/3 of that of the user module, which makes it the perfect complement
to the range of compact modules.
Despite its small size, however, all the modules feature easy-to-read labeling strips and an
integrated addressing socket.
K45 compact modules with four digital inputs.
These compact modules house the communications electronics and standard M12
connections or M8 screw-type or snap-on connections for the inputs. Up to four sensors
can be connected to the compact module.
K45 compact modules with max. four digital outputs.
These modules have up to four digital outputs with an M12 connector.
K45 compact modules with two digital inputs and outputs.
These modules each have two digital inputs and outputs with an M12 connector.
K45 compact modules are available as standard or A/B slaves.

8.4.5 Digital K20 input/output modules - field IP67
8.4.5.1 Overview
K20 compact modules
The range of AS-Interface compact modules has now been extended to include the K20
compact modules which, with a width of just 20 mm, are characterized by their slimline
design. Due to their small dimensions, these modules are particularly suitable for
applications involving industrial robots in production engineering where space for the
modules is extremely limited.
The K20 modules are connected to AS-Interface using a round cable with an M12 cable plug
instead of the AS-Interface flat ribbon cable. The AS-Interface bus cable and 24 V DC
auxiliary supply are routed in a joint round cable, which allows for an extremely compact
design.
Since the round cable is so flexible, the modules can also be easily installed on moving
machine parts, an application for which they are particularly suitable because their
non-encapsulated design makes them extremely light.
When ground cables are used, many users choose to lay the AS-Interface bus cable in a
round cable. In this case, K20 modules can be connected directly to the round cable. An
adapter from the flat ribbon cable to the round cable is not required.
The range of K20 compact modules comprises not only standard AS-Interface modules but
also an ASIsafe version for connecting safety-oriented sensors (e.g. EMERGENCY STOP
buttons or protective door monitoring). As far as is technically feasible, all AS-Interface K20
modules support the extended address mode (A/B addresses) in accordance with
AS-Interface Specification 2.1, which allows 62 nodes to be connected to an AS-Interface
network. In extended address mode, the K20 module with four inputs and four outputs
operates in accordance with AS-Interface Specification 3.0 which, for the first time, also
permits four outputs for an A/B slave and, in turn, 248 inputs and 248 outputs in the
maximum configuration of an AS-i network.
To save even more space, the sensors and actuators can be connected via M8 connectors.
Alternatively, an M12 connection with a Y assignment is also available.
Installation
The K20 modules are secured with two screws. A mounting plate is not required. The
modules can be installed not only on the front but also on the side, which saves space and
provides them with additional protection (e.g. on DIN rails).

8.4.5.3 Setting the AS-i address
The K20 modules are addressed via the same socket as for the bus connection. The module
is addressed by connecting it to the addressing unit (e.g. 3RK1 904-2AB01) with a standard
M12 connection cable (2 or 3-pin) (e.g. 3RX8 000-0GF32-1AB5). If the older version of the
addressing unit (3RK1 904-2AB00) is used, a special addressing cable (3RK1 901-3RA00) is
required to connect the module to the addressing unit. Once the address has been set, the
addressing cable is unplugged and the module is connected to the bus cable. Four or
five-pin connection cables must not be used for addressing purposes.
As far as technically possible, all K20 modules (not ASIsafe versions) support extended
address mode and can be addressed with an A or a B address. In this way, up to 62 slaves
can be connected to an AS-Interface network. The version with four inputs and four outputs
(3RK2 400-1CT30-0AA3) functions in accordance with the new AS-Interface Specification
3.0, which means that A/B slaves can use four outputs (instead of just three as is the case
with Specification 2.1). Note, however, that this module can only be operated with a new
master in accordance with AS-Interface Specification 3.0 (e.g. new DP/AS-i LINK Advanced)
and the cycle times for the outputs in this case can reach a maximum of 20 ms.

Connection examples for K20 modules
The following general conditions must be taken into account:
The installation guidelines for AS-Interface must always be observed. The max.
permissible current for all M12 connection cables is restricted to 4 A. The cross-section of
these cables is only 0.34 mm². To connect the K20 modules, the M12 connection cables
mentioned above can be used for the spur lines. The voltage drop induced by the ohmic
resistance (approx. 0.11 Ω/m) must be taken into account.
The following maximum lengths apply to round cable connections whereby AS-i and
UAUX are carried in the same cable:
For each spur line from the branch to the module: max. 5 m

8.4.6 Analog K60 input/output modules - panel IP67
8.4.6.1 Properties
The most important properties of the K60 analog modules
Analog modules can be integrated in AS-Interface just as easily as digital modules.
Analog values can be easily recorded and output locally.
Preprocessing the analog value transmission in the master allows the analog values to be
evaluated quickly and easily.
Up to four values can be recorded via an analog module.
Specification 3.0 with fast analog modules (to profile 7.A.9) also offers the following features:
A/B technology (i.e. up to 62 analog modules can each be connected to one AS-i
master).
Variable operation: 12-bit or 14-bit resolution, single or double channel, can be selected
via the ID1 code.
Transfer times twice as fast on average (three or four cycles only depending on the
selected resolution).
Simplified analog value processing with masters that comply with Specification 3.0
(DP/AS-i LINK Advanced).
8.4.6.2 Overview
AS-Interface analog modules in the K60 compact series record or supply analog signals
locally. These modules are connected to the higher-level controller via an AS-Interface
master in accordance with Specification 2.1 or 3.0.

AS-Interface system
214 System Manual, 11/2008, 3RK2703-3BB02-1AA1
The input modules to profile 7.3/7.4 are available with two or four input channels. The
two-channel module can also be switched for use with just one input channel, which means
that the analog value is available more quickly. To switch the module, a jumper is connected
to socket 3. Analog modules to profile 7.A.9 achieve transfer times twice as fast as those to
profile 7.3/7.4. Among other things, you can use the ID1 code to select whether the module
is operated with one channel or two.
The output modules are available as two-channel modules as standard.
The input and output channels are electrically isolated vis-à-vis the AS-Interface network.
If sensors with increased power requirements (total ≥ 46 mA) are to be connected when
analog input modules are used, additional power must be supplied via the auxiliary voltage
rather than via the internal supply (flat cable, black). When the auxiliary power is connected,
the sensor supply is short-circuit proof (max. 500 mA). No auxiliary power is required for
output and resistor/thermoresistor modules. The auxiliary power cable can be "looped in" for
other modules, however.
The "AS-Interface Analog Modules Profile 7.3, Profile 7.A.9" manual contains extensive
descriptions of the modules along with their technical specifications and detailed information
about operation.

With analog profile 7.3/7.4, at least seven AS-Interface cycles are required to transfer all the
data. In this case, a master that complies with extended Specification V2.1 (or higher) must
be used.
When input modules are used, the complete analog value is available in the AS-Interface
master. Preprocessing is then carried out in the master.
The next time this system function is called up, the user program copies the analog value as
a value to the user program.
The same sequence in reverse applies to analog value transfer for the output modules.

The total processing time (ttotal) for the complete transfer process from 1/2 inputs is
calculated as follows:
Conversion time tc
AS-i transfer time ttransfer (with cycle times of 5 ms / 10 ms)
PLC transfer time tPLC
This results in the following maximum times until the analog value with profile 7.3/7.4 is
available:
1 channel 2 channels 4 channels
Total transfer time Max. 95 ms Max. 235 ms Max. 435 ms

8.4.6.4 Parameterization
For a detailed description of how to set parameters with AS-i, see Parameterization
(Page 619).
The parameters are sent to the AS-i master via the CPU. Function block FC "ASI_3422"
(FC 7) is required for the S7-300 controller.
FC 7 is available on a disk supplied with the manual for CP-343-2 and Link 20 E. When the
CPU is booted, FC 7 should execute the command "write_extended_parameter_list" (3CH),
for example.
(This is integrated in HW Config as of SIMATIC STEP 7, V 5.4.)
Modules that comply with slave profile 7.A.9 require a "V3 Extended Master" profile M4.

Wiring the two-channel input modules with one input
The modules with order numbers 3RK1207-.BQ40-0AA3 with two inputs can also be
operated with one input. This increases the speed at which the input signal is transferred.
To do so, pin 1 and pin 2 must be connected to each other at socket 3. A jumper
(3RK1901-1AA00) can also be used for this purpose.

8.4.7 SlimLine digital input/output module - cabinet IP20
SlimLine modules of the S22.5 and S45 series
The AS-Interface module series for the SlimLine cabinet with degree of protection IP20
saves space in cabinets or in distributed on-site boxes. The main feature of these modules is
that they are extremely slim (width of between 22.5 and 45 mm).
Screw or spring-loaded terminals can be used to connect standard sensors/actuators and
the AS-Interface cable.
All modules are equipped with LEDs on the front, which indicate the status of the module.
An addressing socket on the front also allows the module to be addressed once it has been
installed.
In addition to the digital input/output modules, S22.5 modules are available with special
functions. These include:
Counter module
Ground fault detection module
The new AS-Interface Specification 3.0 extends the AS-Interface bus system to include a
range of new features. Extended address mode (A/B addresses) allows 62 nodes to be
connected to an AS-Interface network. With extended address mode to Specification 3.0,
A/B slaves can now, for the first time, support four outputs (instead of just three outputs as
defined in Specification 2.1). In the maximum configuration of an AS-Interface network,
therefore, this means that 248 inputs and 248 outputs are available in an AS-Interface
network.
Modules with four inputs and four outputs as A/B slaves in accordance with Specification 3.0
are also available for the cabinet as SlimLine module S45.
Note
Note that the modules to spec. 3.0 can only be operated with a new master to AS-Interface
specification 3.0 (e.g. a new DP/AS-i LINK Advanced or IE/AS-i LINK PN IO) and that the
cycle times for the outputs in this case must not exceed 20 ms.

The 16 inputs are divided into four groups each comprising four inputs.
Only one group at a time can be active. The PLC activates each group one after the other
and reads the four items of input data to the process image for the inputs (PII). The user
program assigns the input data to the relevant groups, that is, the output image (POI) of the
PLC must match the set output on the module otherwise input data will be read by the wrong
group.
If the AS-Interface transfer procedure is not functioning properly, it can take up to three
AS-Interface cycles (15 ms) before the output image (OI) of the slave matches the output
image of the master and, in turn, the PLC. It can also take up to three AS-Interface cycles to
transfer the input image of the slave. If more than three consecutive AS-Interface cycles are
required to send telegrams to the relevant slave, a "configuration error" is output on the
master. The input image in the master is set to "zero" and the error bit in the PLC is set.

Figure 8-30 F90 cycle
In this example, the OI and II in the master and slave do not match until after six
AS-Interface cycles. The PLC cycle is asynchronous vis-à-vis the AS-Interface cycle, which
is why the time required for the OI and II of the master and PLC to match increases by one
AS-Interface cycle and one PLC cycle.
Formula for the cycle time:
4 x ((6 x 5 ms) + 5 ms + 10 ms) =180 ms

Overview
The following modules with special functions are available for AS-Interface:
Counter module:
counts input pulses.
8.5.1 Counter module
8.5.1.1 Overview
Counter module
This module is used for transferring hexadecimal count values (LSB=D0, MSB=D3) to a
higher-level controller, whereby the count value is incremented by one every time a valid
count pulse is received at terminal 8. The module counts from 0 to 15 and then starts again
at 0. The controller adopts the current value and determines the pulse count between two
host calls by calculating the difference from the previous value. The difference is added
together to yield the total number of count pulses.
To transfer unique values, no more than 15 count values must be present between two host
calls or AS-Interface master calls at terminal 8. The maximum permissible transfer frequency
is calculated from these times:
fTrmax = 15 / Tmax
Tmax: max. possible transfer time from slave to host
A further condition for the maximum frequency is the required pulse shape. To ensure that
the counter adopts a pulse as being "valid", a low must be applied for at least 300 µs and a
high for at least 1 ms at the input. This results in a controller-independent maximum
frequency of:
fZmax = 1 / 1.3 ms = 769 Hz for the counter module (see the following diagram).

The counter is only active for the reset parameter P2 (default). When P2 is set, the counter is
deleted and the incoming count pulses are not registered until P2 is reset.

Figure 8-41 Sample configuration with two compact starters
Three power connectors (-X1, -X2, -X3) are used for supplying (-X1) and routing (-X3) the
load power supply (energy bus) as well as for connecting the load itself (-X2). Prefabricated
power connection cables can be used to connect compact starters that are directly adjacent
to each other. The maximum number of starters that can be supplied via one power cable
depends on the maximum permissible aggregate current (max. 4 mm2 = approx. 35 A).

8.6 Switching devices with integrated AS-i connection
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 271
DS/RS compact starters (electromechanical)
Electromechanical compact starters comprise a standard switchgear assembly with SIRIUS
circuit breakers for short-circuit/overload protection and SIRIUS contactor(s) for switching
under normal operating conditions. Electromechancal starters not only offer a number of
benefits including safe, electrical isolation during switch-off or in the event of a trip and
integrated, non-fused short-circuit protection, but are also reasonably priced. The
electromechanical versions can also be used to switch direct currents.
Configuration note: in temperature-critical applications, you are advised to operate
circuit-breakers in the lower setting range.
EDS/ERS compact starters (electronic)
Electronic compact starters EDS (direct-on-line starters) and ERS (reversing starters)
comprise an electronic overload protection system and an electronic motor starter protector
unit.
The benefits of these electronic compact starters include a broad setting range for overload
protection (just two variants cover a power range of up to 2.2 kW at 400/500 V AC), a highly
wear resistant motor starter protector unit, a current detector (for monitoring the power
connectors), emergency operation in the event of overload, and a remote reset function via
AS-Interface after an overload trip.
The ERS compact starter is designed for direct startup in reversing duty. The electronic
overload protection system and the tripping behavior in the event of an overload are set
directly on the device.
Version with brake contact
All compact starters are available with an optional, separately-controlled brake contact for
electrically-operated motor brakes. For motor brakes supplied externally, the 24 V DC is
supplied together with the load voltage via the power connector at -X1. The power is routed
via -X3 to supply the next compact starter at -X1. The 24 V DC for the brakes is only
jumpered in the devices with a brake contact. During configuration, make sure that these
starters are positioned next to each other.
All compact starters can be equipped with a brake contact for 500 V DC with a 400 AC brake
contact.
Hand-held device
The hand-held device allows the compact starter to be operated locally and completely
autonomously when the auxiliary power is present. In addition to standard manual operation,
it is, therefore, possible for local switching operations and test runs during
pre-commissioning (e.g. for testing the motor direction) to be performed with a functioning
automation level if the PLC/bus system fails (emergency operation). A connection cable can
be used to connect the hand-held device directly to the socket under the transparent cover
on the compact starter.

AS-Interface system
272 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Free inputs
The compact starters are also equipped with two free inputs. The input signals are forwarded
directly to the higher-level controller and not evaluated in the compact starter.
The M12 socket has a Y assignment. The signal inputs are located on PIN 2 and 4. This
enables an optical proximity switch to be connected, which supplies a signal and the
message "dirty".
An M12 Y coupler plug can be used to divide the signal inputs over two M12 sockets, which
means that two separate sensors can be connected.
Setting the AS-i address
As with the input/output modules, the AS-i address of the starter can be assigned via the
addressing socket on the front (under the transparent cover).

8.6.2 AS-Interface motor starters (24 V DC, IP65 / IP67)
8.6.2.1 Overview
24 V DC motors and the associated sensors can be be connected quickly and easily on site
with the AS-Interface K60 24 V DC motor starters for the lowest power range up to 70 watt.
A total of three different variants are available in the following versions:
Single direct-on-line starter (without brake, with connectable quick-stop function)
Double direct-on-line starter (with brake and connectable quick-stop function)
Reversing starter (with brake and connectable quick-stop function)
M12 connectors are used to connect DC motors to the module. The yellow AS-Interface
cable is all that is required for supplying the sensors and electronics in the module. An
auxiliary voltage (24 V DC), which is supplied via the black AS-Interface cable, is required for
supplying the outputs only.
Quick-stop function
All AS-Interface 24 V DC motor starters are equipped with a quick-stop function, which can
be connected/disconnected as required via a switch integrated in the module. Quick stop
allows a connected motor to be switched off immediately when the sensor signal (high) is
present without the need for a "diversion" via the PLC control program. The switch for the
quick-stop function is located next to the input sockets and is protected by an M12 screw
cap.
Switch position 0 to 3: quick stop OFF
Switch position 4 to 9: quick stop ON
When quick stop is activated ("ON"), the assigned output OUT1 (OUT2; OUT1 for reversing
starters in reversing duty) is switched off without the intervention of the higher-level PLC
when signal "1" is present at the associated input IN1 (IN3).
Brake
Double direct-on-line starters and single reversing starters are equipped with an integrated,
fixed brake function, that is, as soon as the output signal has been set to "0", the motor is
slowed down when the motor connection is short-circuited. This function cannot be used to
control mechanical brakes.
Single direct-on-line starters are not equipped with a brake function, which means that the
motor coasts to standstill once it has been switched off.
Commissioning via integrated buttons
Buttons integrated in the module (located under the output socket) can be used to switch on
the associated motor directly. The buttons are protected by an M12 screw cap.

The LEDs (Page 173) on the DC motor starters are the same as those for the standard K60
compact modules.
If an output short circuits, it is switched off without a feedback message being sent to the
master (no display via LEDs). The module is ready for operation again when the affected
output is first switched off and then switched to the required operating status.

8.6.3 ECOFAST motor starters
8.6.3.1 Overview
ECOFAST starters
The AS-Interface ECOFAST starter is a fully pre-wired (internally) load feeder with degree of
protection IP65 designed for switching and protecting all types of three-phase load up to
4 kW at 400/500 V AC (electromechanical starters), up to 5.5 kW (electronic soft starters or
electronically switching starters), and up to 1.5 kW (electronic speed controllers), usually
standard three-phase motors in direct operation mode or reversing duty.
All ECOFAST starters support reversing duty.
The starter comprises either an electromechanical switchgear assembly or an electronic
overload protection system and motor starter protector unit.
Seven LEDs integrated in the cover are used for diagnosing AS-Interface and the auxiliary
power.

The Han Q4/2 power connector is used for supplying the consumer power supply (energy
bus). Prefabricated power connection cables and a power T unit can be used to connect
ECOFAST starters. The maximum number of starters that can be supplied via one power
cable depends on the maximum permissible aggregate current (max. 6 mm2 = approx. 40 A).

Variants
ECOFAST RS starters (electromechanical)
Electromechanical starters comprise a standard switchgear assembly with SIRIUS circuit
breakers for overload protection and SIRIUS contactor(s) for switching under normal
operating conditions. Internal fuses provide short-circuit protection. Benefits of
electromechanical starters include safe, electrical isolation during switch-off or in the
event of a trip, the broad setting range (just two variants cover a power range up to 4 kW
at 400/500 V AC), and remote reset via AS-Interface after an overload trip. They are also
reasonably priced.
ECOFAST ERSS starters (electronic)
Electronic ERSS starters (reversing soft starters) comprise an electronic overload
protection system and an electronic motor starter protector unit.
The benefits of these electronic ECOFAST starters include a broad setting range for
Slaves
8.6 Switching devices with integrated AS-i connection
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 289
overload protection (just two variants cover a power range of up to 5.5 kW at
400/500 V AC), a highly wear resistant motor starter protector unit, a current detector (for
monitoring the power connectors), and a remote reset function via AS-Interface after an
overload trip.
ERSS starters are designed to be started directly in reversing duty and for soft start mode
(as well as reversing duty). Electronic overload protection and the switch-off behavior in
the event of an overload are set directly on the device via the local interface.
ECOFAST R2SS starters (electronic)
Electronic R2SS starters (duo reversing soft starters) comprise an electronic overload
protection system and an electronic motor starter protector unit. The R2SS starters can
cover a power range of up to 1.5 kW at 400/500 V AC.
The benefits of these electronic starters include a highly wear resistant motor starter
protector unit, a current detector (for monitoring the power connectors), the capability to
run at two speeds, and remote reset via AS-Interface after an overload trip.
The R2SS starter is designed to be started directly in reversing duty as well as with soft
start startup/braking. Electronic overload protection and the switch-off behavior in the
event of an overload are set directly on the device via the local interface.
Version with brake contact
All ECOFAST starters are available with an optional, separately-controlled brake contact for
electrically-operated motor brakes. The output voltage is 400 V AC.
Version with temperature sensor
If required, ECOFAST starters can be equipped with an optional function for evaluating a
temperature sensor. Either a thermoclick or type A PTC can be used as a temperature
sensor.
Hand-held device
The hand-held device allows ECOFAST starters to be operated locally and completely
autonomously when the auxiliary power is present. In addition to standard manual operation,
it is, therefore, possible for local switching operations and test runs during
pre-commissioning (e.g. for testing the motor direction) to be performed with a functioning
automation level if the PLC/bus system fails (emergency operation). A connection cable can
be used to connect the hand-held device directly to the local interface on the ECOFAST
starter.

Free inputs
ECOFAST starters are also equipped with two free inputs. The input signals are forwarded
directly to the higher-level controller, and can also be evaluated directly in the ECOFAST
starter.
The M12 socket has a Y assignment. The signal inputs are located on PIN 2 and 4. This
enables an optical proximity switch to be connected, which supplies a signal and the
message "contamination".
An M12 Y coupler plug can be used to divide the signal inputs over two M12 sockets, which
means that two separate sensors can be connected.
Parameterizing the ECOFAST starter
The "Motor Starter ES 2006" (or more recent version) or "Switch ES Motorstarter" (name of
the predecessor version) software is required for parameterizing the ECOFAST starters.
The motor starters are set to the maximum rated current (factory setting).

8.6.4 AS-Interface load feeder modules
8.6.4.1 Overview
Load feeders
AS-Interface load feeders (3RA5) allow circuit-breaker/contactor combinations to be quickly
and easily connected to AS-Interface.
Figure 8-52 Direct-on-line starter 3RA51, reversing starter 3RA52, and fuseless load feeder
3RA5110
Direct-on-line and reversing starters with SIRIUS switching devices of size S00 up to 10 A
and size S0 up to 16 A are available. Complete feeders require an auxiliary voltage of
24 V DC.
A complete feeder comprises an AS-i load feeder module, a circuit breaker, one contactor
(direct-on-line starter) or two contactors (reversing starters), and a holder for busbar systems
(40 mm or 60 mm busbar clearance), including tested pre-wiring.
The components can also be ordered separately if wiring is provided by the customer.

AS-i load feeder modules
Figure 8-53 AS-Interface load feeder module
The AS-i load feeder modules are available in the following variants:
With a 24 V DC auxiliary voltage for outputs
2 inputs / 1 output
4 inputs / 2 outputs
With a 120/230 V AC auxiliary voltage for outputs
2 inputs / 1 relay output
3 inputs / 2 relay outputs
The connection to the higher-level automation system is established via the AS-Interface
interface for the load feeder module. A standard, unshielded litz wire can be used as a data
cable and for supplying the auxiliary voltage.
Two 2-pin connectors with insulation displacement are used to connect the AS-Interface
cable (yellow connector) and auxiliary voltage (black connector for 24 V or red connector for
120 / 230 V). Standard litz wires of between 0.5 mm2 and 0.75 mm2 can be used as
connection cables.
The feedback messages from the circuit breaker and contactor(s) can be queried with the
inputs. The inputs are supplied from the AS-Interface voltage.
The outputs are used for energizing the contactor coils directly. Since the outputs are
equipped with integrated overvoltage protection, no additional measures need to be taken
with regard to the contactors.
The outputs are supplied via the separate auxiliary voltage, which allows a selective
EMERGENCY STOP concept to be easily implemented.

AS-Interface slaves
Built-in AS-i modules are available for the housing for integrating AS-i. These slave modules
can be snapped in to the base plate of the housing without the need for tools.
Thanks to the integrated busbar adapter, the modules can also be snapped on to a DIN rail
outside the 3SB3 housing so that they can be used for other configuration concepts.
The modules are available in the following versions:
Standard module for connecting four switching elements and four LEDs, in two housing
variants
For installation in plastic housing (with 2-6 control points)
For installation in metal housing (with 2-6 control points)
A/B module for connecting four switching elements and three LEDs, in two housing
variants
For installation in plastic housing (with 2-6 control points)
For installation in metal housing (with 2-6 control points)
ASIsafe module for connecting safety-oriented signals with two contacts (e.g.
EMERGENCY STOP) in three housing variants
For installation in plastic housing without protective collars (with 1-6 control points)
For installation in metal housing without protective collars (with 1-6 control points)
For installation in plastic or metal housing with protective collars (with 1 control point)
Figure 8-67 Standard or A/B module (left) and ASIsafe module (right)
Scope of application
In a 3SB3 housing, the AS-Interface modules 4DI/4DO and 4DI/3DO can query four
contacts. AS-Interface module 4DI/4DO can also control four indicator lights, while module
4DI/3DO can control three indicator lights. The required power is provided by the
AS-Interface system. In conjunction with an A/B-capable AS-Interface master, up to
62 4DI/3DO modules can be operated in one AS-Interface network.

AS-Interface system
320 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Installed in a 3SB3 housing, the AS-Interface safety module is used for detecting
safety-related switching statuses of one or two-channel EMERGENCY OFF buttons with
floating contacts. For this purpose, a code table with 8x4 bits is transferred via the
AS-Interface bus and evaluated by the safety monitor.
When operated properly, the system fulfills safety category 4 to EN 954-1. If an
EMERGENCY OFF actuator is queried on just one channel (terminals for F-IN2 jumpered by
means of wire), the system only fulfills safety category 2.
In accordance with IEC 61508, the module can be used in loops up to SIL 3. The PFD value
of the module is insignificant vis-à-vis the PDF value of the evaluation unit (e.g. AS-i
monitor).
Always read the notes in the Safety Integrated manual and operating instructions for the
safety monitor.
Setting the AS-i address
To assign the AS-i address, you need to open the housing. The addressing socket is located
on the side of the built-in AS-i module. The address is assigned as usual using the AS-i
addressing unit. If the housing contains more than one AS-i module, you have to assign
multiple addresses.

8.7.2.3 Connection
Housing and modules
Instead of the standard method using multi-core connection cables, the elements are wired
directly to one or more AS-Interface slave modules in the housing. Switching elements are
connected to inputs and LED elements are connected to outputs. The 2-core AS-i cable is all
that is required for establishing a connection with the PLC.
An auxiliary voltage (black 24 V cable) is not required because the outputs/LED elements
are supplied with power directly via the AS-i voltage.
The following secure connection options are available for connecting the AS-i cable:
M12 socket
Cable gland for AS-i flat cable
Cable gland for round cable
The following quick-assembly option is also available:
Connection clip with insulation displacement method for AS-i flat cable
Figure 8-68 Different connection options
Inputs or outputs that are not required for switching elements or LED elements can be routed
externally (e.g. to connect external sensors) via an M12 socket through the second cutout in
the housing.
Connecting the AS-Interface slave modules to the control and signaling devices
The modules are connected to the control and signaling devices via connecting cables.
Standard or A/B modules require 14-pin connectors while ASIsafe modules require 8-pin
connectors.
The connectors are available as complete wiring units.

Data assignment of pre-wired (in factory) housing:
The positions of the control points in the housing are labeled with A, B, C, etc. "A" is located
at the bottom (or on the left if the device is mounted horizontally).
1. Safety-oriented control points (e.g. EMERGENCY STOP buttons) require one complete
ASIsafe module.
2. The inputs and outputs on standard and A/B modules are assigned in ascending order in
accordance with the position of the switching elements or LED elements.
3. If more than one standard or A/B modules are installed in the housing:
In the case of illuminated control points (illuminated pushbuttons / knobs), the LED and
switching element are wired to the same AS-i module. If the control point has two switching
elements (illuminated knob with 3 positions), the LED and the "lower" switching element are
wired to the same AS-i module. This means that individual outputs in this consecutive series
may remain unused.

8.8 Signaling columns with AS-Interface connection
8.8.1 Overview
On machines or in automatic processes, the 8WD4 signaling columns are used for
monitoring complex procedures or provide visual/acoustic warnings in emergencies.
In the case of standard signaling columns, the signaling elements (e.g. lamp elements) are
placed vertically on the connection element. In the connection element, a signal cable (and
joint ground cable) must be connected for each signaling element.
In the case of AS-Interface signaling columns, an AS-i adapter element is placed on the
connection element. The signaling elements are placed vertically on top of this. Only the
2-pin AS-i cable (and auxiliary voltage, if required) needs to be connected in the connection
element. The signaling elements are controlled as AS-i outputs. The outputs are connected
to the signaling elements automatically in ascending order.

8WD44 series (70 mm diameter)
The following AS-i adapter elements are available for the 8WD44 series:
Standard slave with 4 electronic outputs
A/B slave with 3 electronic outputs
You can use a slide switch on the bottom of the adapter element to select the cable via
which the signaling elements are supplied:
Switch position "internal" Power supply for the signaling elements from the AS-i cable.
An auxiliary voltage does not need to be connected.
Switch position "external" Power supply for the signaling elements from the auxiliary
voltage.
24 V DC auxiliary voltage must be connected.
Depending on the position of the switch, the power requirements for the signaling elements
must be taken into account when the AS-i power supply unit or auxiliary voltage power
supply unit is dimensioned.
In the event of an overload, the outputs are shut down and an I/O error is reported to the
AS-i master.

8.9 AS-Interface connection for LOGO!
8.9.1 Overview
The LOGO! Modular logic module is a user-friendly, cost-effective solution for simple
open-loop and closed-loop control tasks in domestic applications/installation engineering,
cabinet construction, mechanical and apparatus engineering, and so on. It can also be used
for preprocessing signals for other controllers.
To increase the number of inputs and outputs of the basic module LOGO! Modular Basic /
Pure, digital and analog expansion and communication modules can be connected.
LOGO! communications module CM AS-Interface allows a LOGO! module to be connected
to an AS-i system. It can be combined with any LOGO! modular basic and pure variants.
Figure 8-81 LOGO! CM AS-Interface expansion module (right) connected to a LOGO! basic module
(left)
The LOGO! CM AS-Interface is an AS-i slave.
It does not support master functionality, which means that it cannot be used to control other
AS-i slaves.
As a result, data cannot be exchanged directly between two LOGO! devices. Data is always
exchanged via the AS-Interface master.
The LOGO! CM AS-Interface exchanges four digital input and four digital output statuses
with the higher-level controller (PLC) via an AS-i master.
This input and output data can be interconnected in the LOGO! program in the same way as
standard inputs and outputs.
The LOGO! program does not make a distinction here between the virtual inputs/outputs (of
the AS-Interface communication module) and the standard inputs/outputs (which are wired to
physical switches/contactor coils via terminals, for example).

Logical assignment
The LOGO! program numbers the inputs and outputs in the same order in which the
modules are connected, starting with I1 (inputs) and Q1 (outputs).
The LOGO! basic module is equipped with eight digital inputs and four digital outputs, which
are addressed in the LOGO! program as I1 ... I8 and Q1 ... Q4. The numbering is continued
if expansion modules are connected.
If a CM AS-Interface communication module is connected next to the basic module, the four
inputs and four outputs on the CM AS-Interface are addressed in the LOGO! program as
I9...I12 and Q5...Q8.
If additional expansion modules with digital inputs/outputs are located between the basic
module and the communication module, the inputs/outputs on the CM AS-Interface shift
accordingly in the LOGO! program.
In LOGO!, an AS-i output (from the point of view of the PLC) is read as an input.
In LOGO!, an AS-i input (from the point of view of the PLC) is read as an output.

Setting the AS-i address
The addressing socket for setting the AS-i address is located on the left-hand side of the
lower terminal strip. The address is assigned as usual using the AS-i addressing unit.
If the module is to be addressed via the addressing socket once it has been installed, you
must disconnect AS-Interface from the power supply beforehand. This is necessary in the
interests of plant safety.
The AS-i address cannot be set via the display of the LOGO! basic module or via the LOGO!
software.

8.10.1 Overview
The contactors 3RT10, 3-pin, sizes S6 ... S12 (for > 45 to 250 kW) with display showing
remaining service life can be ordered with an integrated AS-i connection.
Figure 8-84 Contactor 3RT1056
The contactors require an auxiliary voltage of 96 to 127V or 200 to 277V AC/DC.
An upstream control electronics system supplies the magnet coil with just the power
necessary for ensuring safe switching and stopping,as a result of which a low pick-up and
holding power is required.
The electronic remaining life time (RLT) module determines the actual extent to which the
contact has eroded and outputs a signal message via AS-Interface when the remaining life
time is < 20%. LEDs on the contactor electronics also indicate 40% and 60% remaining life
time.
This means that eroded contacts can be replaced in good time during servicing.

AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 349
Integrated safety systems: ASIsafe 9
The safety-related design of AS-Interface was standardized for all manufacturers in the
"Safety at Work" consortium (sub-group of the AS-i International Association) (see
AS-i-Spec. 3.0). It is marketed by Siemens under the copyrighted name "ASIsafe".
The concept allows both standard and safe data to be used in one single bus system.
EMERGENCY STOP buttons, laser scanners, and a range of other I/Os can be easily and
safely connected directly to AS-i. Existing applications can also be quickly and easily
extended to include safety-oriented functions.
"Safety at Work" is certified by the Technical Inspectorate (TÜV) and approved devices bear
the ASIsafe logo.
Integrating safety-oriented components
ASIsafe enables safety-oriented components (e.g. EMERGENCY STOP control devices,
protective door monitors, optoelectronic protective devices, safety light curtains) to be
integrated directly in an AS-Interface network. These are fully compatible with the standard
AS-Interface components (master, slaves, power supply unit, repeater, etc.) to
IEC 62061/EN 50295 and are operated together on the yellow AS-Interface cable.
The signals from the safety sensors are evaluated by a safety monitor, which not only
monitors the switching signals from the safety sensors but also continuously ensures that
data is transferred properly. The safety monitor is equipped with one or two enabling circuits,
which are configured with one or two channels and are used to switch the machine or plant
to safe mode. Sensors and monitors can be connected anywhere within the AS-Interface
network. More than one monitor can also be used in a network.
A failsafe controller or special master is not required. The master treats safety slaves in the
same way as all the other slaves and receives safety data for information purposes only.
This means that all existing AS-Interface networks can also be extended.
ASIsafe ensures a maximum response time of 40 ms. This is the time between the signal
being applied to the input of the safe slave and the output on the safety monitor being
switched off.
Tested safety
The system is tested and released for worldwide use by TÜV (Germany), NRTL (USA), and
INRS (France). The transmission method for safety-oriented signals is designed in such a
way that applications up to category 4 according to EN 954-1 and SIL 3 according to
IEC 61508 can be implemented.
ASIsafe ensures full compatibility with all other AS-Interface components to EN 50295.

350 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Software
The safety-oriented applications can be compiled and transferred to the monitor using the
configuration software "asimon". The software also supports online diagnosis.
Local ASIsafe solution: the safety monitor
(Page 353)
PROFIsafe ASIsafe solution: the DP/AS-i F-
Link (Page 123)
A number of simple and cost-effective safety
solutions are available. The local ASIsafe
solution only needs two components: a
safety monitor and safe slaves. Failsafe
PLCs or special masters are not required.
The safety monitor monitors the safe inputs
acquired via the safe slaves, links them
using a parameterizable logic, and ensures
safe shutdown by means of a built-in safety
relay.
The data is transferred via a dynamic, safe
protocol. In each cycle, the safety monitor
expects from each slave a specific telegram
that changes continuously in accordance
with a defined algorithm. Configuration
software is used to parameterize the
shutdown logic of the safety monitor,
whereby it can respond accordingly in each
case when the safe nodes trip. If no
telegram is received (e.g. if a fault or alarm
occurs), the safety monitor shuts down after
max. 40 ms (worst case) via its two-channel
enabling circuits.
DP/AS-i F-Link allows you to leverage the
benefits of AS-i in a wide range of safety
applications since it allows the use of AS-i in
failsafe SIMATIC or SINUMERIK controllers.
It closes a crucial gap in bus-based safety
technology in that it ensures that ASIsafe
telegrams are converted to the PROFIsafe
protocol. Safe signals are acquired as usual
with the robust IP67 ASIsafe slaves. The
existing F PLC is responsible for evaluating
them. Responses are also made at the
PROFIsafe level, either by F-DO/F-RO
modules in the central rack or by means of
the failsafe distributed I/Os. F-Link is the
best choice in the following cases:
When large amounts of safe slaves are
used
When numerous trip circuits have been
installed
For safety-oriented further processing at
the higher-level field bus levels
For extensive, nested logical operations
The safety monitor can be diagnosed via the
controller. This has many benefits, in
particular no additional wiring is necessary
for the safety components. Ready-made
images for operating and monitoring tasks
also allow users to visualize the
safety-oriented events on SIMATIC HMI
panels.
And the level of TIA is greater than ever:
configuration and parameterization is carried
out via STEP 7 HWConfig, as is the case
with PROFIsafe slaves. The safe logic is
programmed with the "unlimited" resources
of STEP 7 Distributed Safety in F-KOP or
F-FUP. The comprehensive library of
TÜV-certified function blocks ensures highly
efficient and structured user programs.
Diagnosis is also carried out using the
system functions provided by STEP 7 as
well as locally on the devices by means of
messages on the display.

9.1 Safety monitor
Functional principle
The safety monitor monitors data communication on the AS-Interface cable. For safe slaves,
dynamic code sequences (8x4 bit data sequence), which are stored in every slave, are
transferred.
These are "learnt" by the safety monitor during commissioning. During operation, the safety
monitor compares in each cycle the target and actual sequence and, if any discrepancies are
identified (e.g. due to device failure, communication faults, etc.), initiates a safe shutdown
within 40 ms. The restart time is 100 ms. A range of safe field and cabinet modules as well
as intelligent safety sensors and control devices with an AS-Interface chip are available as
slaves.
Bus communication and the data protocol have been deemed safe by the BIA and the
technology has been certified by TÜV.
The system can be used up to category 4 to EN 954-1 or up to SIL 3 to IEC 61508 [10] and
can be used for stop category 0 and 1 to EN 60204-1.

354 System Manual, 11/2008, 3RK2703-3BB02-1AA1
9.1.1 Overview
The safety monitor is at the heart of ASIsafe. A safe application is configured with a PC via
the safety monitor. A range of different application-specific operating modes can be selected
here. These include the EMERGENCY OFF function, tumbler, or stop category 0 or 1.
To leverage the benefits of the AS-Interface diagnostic options, the monitor can also be
operated with the AS-Interface address. All the diagnostic options can be used further in the
higher-level PLC by means of the diagnostic block for STEP 7 supplied with the ASIsafe CD.
The monitor is available in two versions:
Basic safety monitor with an entry-level range of blocks and basic functionality
Expanded safety monitor with advanced features and functionality
Both versions are each available with one or two two-channel enabling circuits.
The safety monitor is used in an AS-Interface bus system for monitoring protective devices
(e.g. EMERGENCY OFF buttons). It fulfills safety category 4 (to EN 954-1).
In accordance with IEC 61508, the safety monitor can be used in loops up to SIL3. The PFD
value of the entire loop must be calculated by the user.
ON period (in months) Total operation time (in years) PFD PFH

NOTICE
Depending on the safety components selected, the safety system as a whole can also be
classified in a lower safety category.

When the expanded safety monitor is used, the number of devices that the safety monitor
can handle increases from 32 to 48. This allows more complex and larger applications to be
simulated in the safety monitor.
OR logic operation
At the logic level, two elements can be ORed in the basic version and up to six elements in
the expanded version.
AND logic operation
With the expanded safety monitor, an AND operation can be added to an OR operation in
addition to the standard AND operation in the main path of an enabling circuit. More than two
elements can be linked in this AND.
Functions of the basic safety monitor
Wildcards and deactivation of monitoring modules:
wildcards are available for configuration purposes. These wildcards are used during
configuration and diagnosis and, if required, are easy to activate. This allows for simple,
user-friendly configuration, even when the plant configurations vary.

AS-Interface system
356 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Fault reset:
If a module detects a fault, the AS-Interface safety monitor switches to the fault status. In
this case, a differentiated fault reset is triggered. The fault reset can be activated by a
standard AS-Interface slave (e.g. a button) and is only effective at module level. The main
advantage of this is that only the module locked in a fault is reset rather than the entire
safety monitor.
Buffer storage and "Diagnostics hold"
Momentary disconnections are saved in a buffer memory for diagnostic purposes.
Disconnections can also be "frozen" until an acknowledgment is received via a standard
slave ("Diagnostics hold" function).
Additional functions of the expanded safety monitor
The following additional features are only available with the expanded safety monitor:
Safe time functions
Timers with the following functions are available:
ON delay
OFF delay
Pulse
"Button" function
Additional acknowledgment option for restarting the system by means of an additional
button. In addition to the "Service" button on the safety monitor, its function (restarting the
system) can be assigned to any button on a command and signaling device by
configuring this in the asimon software.
Contact debouncing
A bounce time after which the system restarts can be set for debouncing contacts.
Compatibility
Existing configurations can be transferred to the "new" safety monitor without changes.
All functions are designed for category 4 to EN 954-1; the safety monitor, monitoring and
evaluation unit, as well as the slaves have been certified by TÜV to IEC 61508, NRTL (USA),
and INRS (France).

Diagnosis via AS-Interface
To forward the diagnosis to the PLC via AS-Interface, the safety monitor requires an
AS-i address. This is assigned using the asimon configuration software (Edit ➜ Information
about Monitor and bus ➜ Diagnosis / Service ➜ AS-interface diagnosis ➜ Monitor base
address).
A function block in the PLC reads the diagnostics data and stores it in a data block. The
function block (incl. description) is supplied with the asimon software.

9.2 ASIsafe modules
9.2.1 Overview
Figure 9-5 ASIsafe modules
Safety modules for AS-Interface (ASIsafe modules) are available for field use in degree of
protection IP67 (K20F and K45F compact modules) and for the control cabinet (S22.5F
SlimLine modules) in degree of protection IP20.
This means that a highly compact module with an optimum price/performance ratio is
available for all types of application.
The following modules are available:
K20F safe compact modules for operation in the field
The K20F module, which is just 20 mm wide, is ideal for applications in which modules need
to be installed in a confined area. The K20F modules are connected to AS-Interface using a
round cable with an M12 cable plug instead of the AS-Interface flat cable, which allows for
an extremely space-saving design. Since the round cable is so flexible, the modules can also
be easily installed on moving machine parts. The K20 modules are also suitable for
installation on moving parts because their non-encapsulated design means that they are
extremely light.
K45F compact safety modules for operation in the field
The platform for the K45F modules covers the following variations:
Connection of switches /safety sensors with contacts ("mechanical"):
K45F 2F-DI: two safety-oriented inputs in operation up to category 2 to EN954-1. If
category 4 is required, the module is equipped with a two-channel input.
K45F 2F-DI/2DO: two standard outputs are available in addition to the safe inputs.
Supplied via the AS-i cable.
K45F 2F-DI/2DO Uaux: like K45F 2F-DI/2DO, supplied only via the black 24 V DC
cable.
Integrated safety systems: ASIsafe
9.2 ASIsafe modules
AS-Interface system
364 System Manual, 11/2008, 3RK2703-3BB02-1AA1
K45F 4F-DI: four safety-oriented inputs in operation up to category 2, two for category
4. Highly compact double slave (uses two full AS-i addresses).
Connection of electronic switches / safety sensors (non-contact protective devices, BWS):
K45F LS (light sensor): safe input module for connecting electronic safety sensors
tested semiconductor outputs (OSSD). In particular, proximity-type protective
equipment, such as active, optoelectronic light curtains and arrays for types 2 and 4 to
IEC / EN 61496, as well as transmitters and receivers are supplied with power by the
yellow AS-i cable. Suitable sensor cables and an optional, separate transmitter supply
module are available as accessories.
SlimLine safety modules S22.5F for use in cabinets and on-site switching boxes.
The SlimLine safety module S22.5F is equipped with two safe inputs. This also ensures that
signals can be safely connected to ASIsafe networks in the cabinet.
In operation up to category 2, both inputs can be assigned separately. If category 4 is
required, the module is equipped with a two-channel input.
Two S22.5F module variants are also available, which are equipped with two standard
outputs in addition to the two safe inputs. These are supplied with power either via the yellow
AS-Interface cable only or via the auxiliary voltage from the 24 V DC cable.

9.3 3SF1 position switches with ASIsafe interface
9.3.1 Overview
Position switches are used to convert the mechanical positions of moving machine parts to
electrical signals.
The 3SF1 position switches comprise a standard position switch and an ASIsafe slave in the
switch housing whose safe inputs are wired to the position switch contacts.
Category 3 to EN 954-1 is achieved with the 3SF1 3 position switch with two-channel
interrogation in the appropriate operating mode. Category 4 can be achieved by combining
the 3SF1 position switch with an 3SE5 position switch.
Figure 9-9 ASIsafe position switches, modular system
Type variants
Position switches are available as:
Standard position switch:
the basic switch and matching actuator head (roller lever, twist lever, plunger, etc.) are
ordered separately.
Position switches with separate control element:
the basic switch is supplied complete with the actuator head (for inserting the control
element). The corresponding control element (for different assembly types) is ordered

9.4 SIMATIC FS400 light curtains and arrays
9.4.1 Overview
The non-contact and active optoelectronic light curtains and arrays for categories 2 and 4 to
EN 954-1 protect operating personal working on or near running machines and plants.
A standard light curtain or array comprises a transmitter and receiver, which must be
installed opposite each other. A transceiver combines the transmitter and receiver, whereby
a passive reflecting mirror (additionally required) reflects the light beams. A number of
transmit and receive diodes are placed one above the other depending on the resolution and
length. The infrared LEDs on the transmitter emit short light pulses, which are picked up by
the receive diodes.

Figure 9-16 Optoelectronic protective devices: Light curtain, light array, and transceiver
(a = transmitter, b = receiver, c = transceiver, d = reflecting mirror)
Light curtains have between 8 and 240 beams of light and are designed for protecting
hazardous areas. Depending on the resolution, they can detect fingers, hands, arms, feet,
thighs, etc.
Light arrays have 2, 3, or 4 beams and are designed for detecting people entering hazardous
areas. They are not suitable for protecting hazardous areas since this requires a device that
can detect fingers, hands, or arms etc.
In the case of transceiver light arrays, the transceiver emits a beam of light from the upper
part of the enclosure, which is then reflected by the reflecting mirror with an offset of 500 mm
(beam spacing) and received again in the lower part of the transceiver enclosure. In this
case, the reflecting mirror is a housing with two mirrors. The range of the transceiver is
specified as the distance between the transceiver and reflecting mirror (if one reflecting
mirror is used). If more than one reflecting mirror is used, the range decreases by 15% with
each additional reflecting mirror. To configure interlinked protective zones, light curtains can
be arranged one behind the other by cascading host and guest devices via plug-in cable
connections. This also allows transmitter/receiver pairs with different resolutions to be
combined.

Setting the AS-i address
The AS-i address of the receiver (or transceiver) can be set by connecting the AS-i M12
connector (pin 1 = ASI+, pin 3 = ASI–) to the addressing unit.
No additional AS-i addressing socket is available.
For 3SF7844 light curtains and arrays, all the receiver electronics are supplied via the AS-i
connection, that is, a max. current of 140 mA is also required when the AS-i address is set.
You are advised to connect an AS-i power supply unit in parallel with the addressing unit so
that the addressing unit does not output an overload signal.
The transmitter does not require an AS-i address.

Additional sensors (e.g. buttons) and actuators (e.g. indicator lights) can be connected to the
local interface in the connection cap of the device.
The assignment of the 8-pin local M12 device socket in the connection cap depends on the
integrated function package. You can use the SafetyLab PC software to individually assign
the inputs/outputs of the local interface to the different device functions.
A local connection box is available as an accessory. This divides the pins of the 8-pin M12
socket into six individual 5-pin M12 sockets, thereby making it easier to connect the sensors
and actuators.
For a description of this, refer to the manual for light curtains/arrays, which is available for
each specific function package.

Cyclic output data (4 bit)
The cyclic output data bits (from the point of view of the PLC) are not evaluated by the light
curtain/array.
Acyclic data
The acyclic parameter data can be used to exchange additional non-safety-oriented data
between the AS-i master and slave. The AS-i master can use a "parameter call" (write
parameter) to send four parameter bits to the slave whereby the slave responds by sending
four parameter echo bits back to the master. The parameter call must be triggered by the
user program. With a SIMATIC S7-300/400, this can be carried out using command 02 of the
AS-i master command interface (FC ASI_3422 (Page 71)). The parameter echo bits can only
be received if the parameter bits were sent.

9.5 SIMATIC FS600 laser scanners
9.5.1 Overview
The laser scanner is a highly versatile optical distance sensor for protecting hazardous
areas.
It uses a laser diode with transmission optics to continuously generate bundled light pulses,
which are scattered over the entire working range by an integrated rotating mirror. If any
objects or people enter the zone, the scanner evaluates the reflected light pulses and uses
the light propagation time to continuously calculate the exact position coordinates. If the
defined protective zone is violated, it initiates an immediate machine shutdown within the
system response time (via a suitable ASIsafe configuration). Depending on the operating
mode, the stop function is reset either automatically or after acknowledgement (via an
optional button that can be fitted on the laser scanner) when the protective zone is free.
The working range of the laser scanner covers 190°. The laser scanner detects people at a
distance of up to 4 meters (protective zone, safety oriented). People and objects can also be
detected at a distance of up to 15 meters for the purpose of outputting warnings (warning
zone, non-safety-oriented).
Four variable (can be set via the PC software) protective zone pairs for the protective and
warning zone mean that the laser scanner can be easily adjusted in line with requirements.
One protective zone pair can be active at any one time. The active protective zone pair can
be selected by means of switching contacts, which are connected to an M12 socket on the
laser scanner.
The laser scanner can be installed in stationary applications (e.g. on machines and in plants)
as well as mobile applications (e.g. vehicles, driverless transportation systems or traversing
trucks). In this way, different working ranges around a robot, for example, can be monitored
whereby the laser scanners operate consecutively with respect to space and time. This can
significantly increase plant availability.

In driverless transportation systems, the four programmed protective zones (SF) (e.g. fast
(SF2), slow (SF1), left curve (SF3), and right curve (SF4)) can be protected. Unlike bumpers
or hoop guards, the laser scanner offers a larger protective zone and, therefore, allows
vehicles to be driven at higher speeds.

Additional information
Laser scanners are available for standard wiring and with an integrated ASIsafe slave (or
also with integrated PROFIBUS interface).
The type variants for standard wiring and other bus systems are not covered here. The
following description only refers to the device with an integrated ASIsafe slave.
For the complete range of laser scanners, see catalog FS10 or visit the A&D Mall at:
www.siemens.com/automation/mall
Choose "Products".
On the left of the screen, choose the product path:
Automation and Drives ➜ Sensor, Measuring and Testing Technology ➜ Fail-safe Sensors
Then choose the products you want and download the required information.
The ASIsafe laser scanner requires a connection to the AS-i cable for bus communication
and a separate 24 V DC supply. It is connected via a 5-pin M12 connector (X1) on the top of
the housing. The laser scanner is assigned an AS-i address.
The scanner is equipped with a restart inhibit function (when a person/object is detected),
which can be activated/deactivated via the software. The optional "Start" button can be
connected via an additional 5-pin M12 connector (X4). A restart signal can also be sent via
AS-Interface (acyclic parameter data).
You can switch between protective zones via a 5-pin M12 socket (X3). The protective zone
pairs are activated by applying 24 V (pin 5) to the corresponding inputs (pin 1 ...4). The
second protective zone pair must always be activated before the first protective zone pair is
deactivated. The switchover must occur within 1 s. The switchover procedure must never be
configured to deactivate all the protective zone pairs. Except during the switchover
procedure, only one protective zone pair must be active at any one time.
The laser scanner complies with the following standards:
Safety category 3 to EN 954-1
Type 3 to IEC 61496-1 or EN 61496-3
LS4soft software
The LS4soft PC software can be used to parameterize and define the protective zones. The
software is required for commissioning and is supplied with the laser scanner. It also offers a
comprehensive range of diagnostic options.
To transfer the configuration and diagnostics data, a special PC cable with an infrared
adapter is required. This must be ordered separately (order no. 3RG7838-1DC). The 9-pin
SUB D connector is connected to the serial interface (e.g. COM1) of the PC. The infrared
adapter is placed in an appropriate position on the top of the ASIsafe laser scanner where it
is secured by a built-in permanent magnet. For more information, refer to the software
manual.

10.1 Extension plug
10.1.1 Overview
An extension plug or extension plug plus can be used to increase the maximum possible
cable length in an AS-Interface segment from 100 m to 200 m.
The extension plug / extension plug plus is a passive component and is installed at the point
in the network that is furthest away from the AS-Interface power supply unit. This point does
not need to be determined exactly; it is sufficient just to connect the extension plug /
extension plug plus somewhere near the end of the cable (≤ 10 m).
It is equipped with an M12 connector and can be connected with an AS-Interface M12
branch with degree of protection IP67.
The extension plug / extension plug plus is equipped with integrated undervoltage detector
for monitoring the AS-Interface voltage to ensure that the required voltage is present even at
the end of the bus cable. Undervoltage is indicated on the extension plug by means of a
diagnostics LED. The extension plug plus is equipped with an AS-i A/B slave and
communicates this diagnostics data directly to the AS-Interface master.
Setting the AS-i address
The AS-i address of the extension plug plus can be set by connecting the AS-i M12
connector to the addressing unit. No additional AS-i addressing socket is available.
The extension plug (not "plus") is not assigned an AS-i address.

Extension plug
If the minimum voltage as defined by the AS-Interface Specification is undershot, this is
indicated on the extension plug when the green LED starts flashing. If the AS-Interface
voltage is sufficient, however, it is lit up continuously. To detect undervoltage, the LED is
configured with a delay so that even momentary voltage dips can be detected.
LED display
LED Possible cause Possible remedial measures
Green Normal operation,
AS-i voltage OK
Flashing green Undervoltage,
AS-i voltage < 26.5 V
Move the AS-i power supply unit.
Increase the cross-section of the
AS-i cable.
Reduce the load caused by
slaves/sensors.
Check whether or not the network
quality is still sufficient despite
undervoltage.
OFF No AS-i voltage,
AS-i voltage connected with incorrect
polarity,
AS-i voltage too low
Switch on the AS-i voltage, connect it
properly,
measure the AS-i voltage
(approx. 30 V DC)
The condition for undervoltage must be present for at least 5 ms in order to be signaled via
the LED. The undervoltage message is displayed for at least 100 ms, even if the voltage only
drops momentarily.
Extension plug plus
The extension plug plus is equipped with an AS-i A/B slave and does not have a diagnostics
LED.
If the minimum voltage is undershot, this event is sent as digital input data directly to the
AS-Interface master. Two different voltage values can be set as the threshold value; these
can be selected by setting the output bits. Two different input bits can be used to distinguish
between brief and longer voltage dips.

If this is insufficient, however, you can use one or more repeaters.
A repeater extends an existing segment with an additional segment, which can have a
maximum cable length of 100 m (without an extension plug) or 200 m (with an extension
plug).
Each segment requires a separate AS-i power supply unit.
The additional power supply can increase the current supply for slaves/sensors and lower
the voltage drop on the AS-i cable.
Properties of the repeater:
Slaves can be installed in both segments (upstream and downstream of the repeater).
The two AS-i cable segments are electrically isolated, that is, fault signals/EMC and
ground faults are blocked on the repeater.
The repeater reconstructs the bit information in the AS-i telegram.
A maximum of two repeaters connected in series can be used if an AS-i extension plug is
not used.
When an AS-i extension plug is used (in segment 1 or/and segment 2), repeaters must
not be connected in series.
Several repeaters can be connected in parallel (star configuration).
When several repeaters are used in a combination of parallel and series connections
(tree configuration), the cable length can be extended to several kilometers. For the sake
of clarity, however, catalogs and brochures usually state maximum total lengths of no
more than a few hundred meters. Even when repeaters are used, the maximum number
of slaves that can be connected is 31 (without A/B slaves) or 62 (with A/B slaves).
Repeaters can also be used in conjunction with ASIsafe slaves and safety monitors or
F-Link.
The AS-i addresses (and any safety monitors) can be distributed across the segments as
required. The only restriction here is that no more than 35 load equivalents are installed
in each segment to prevent the communications voltage from being attenuated
excessively. The following equivalences apply:
Standard slave (incl. ASIsafe slave) ≡ 1 load equivalent
A/B slave ≡ 0.5 load equivalent
Safety monitor ≡ 1 load equivalent
Repeater (per segment connection) ≡ 1 load equivalent
System accessories
10.2 Repeaters
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 421
Other components without an AS-i address (e.g. ground fault detector) ≡ 1 load
equivalent,
Example:
Segment with 20 standard slaves (incl. ASIsafe slaves), 10 A/B slaves, 3 safety
monitors, 1 repeater, 1 ground fault detector.
Result:
20 + 10 x 0.5 + 3+ 1 + 1 = 30; this is a permissible configuration because the load
equivalent is ≤ 35.
The repeater is designed symmetrically, that is, it does not matter whether or not the AS-i
master is installed in segment 1 (upstream of the repeater) or in segment 2 (downstream
of the repeater).
The repeater can be installed anywhere on an AS-i cable. The AS-i flat cable of each
segment is fed through the repeater without interruption. If necessary, the cable can end
in the repeater.
Setting the AS-i address
A repeater is not assigned an AS-i address.

Repeaters can be used to increase the length of the cable. Since repeaters cannot be
connected in series when they are used in conjunction with AS-i extension plugs, this results
in a maximum distance of 400 m between the master and slave and a maximum cable
extension of 600 m (master in the middle of the network). Repeaters can be connected in

System Manual, 11/2008, 3RK2703-3BB02-1AA1 425
10.3 Extenders
10.3.1 Overview
The extender has almost the same function as the repeater, but with the following
differences:
The AS-i master only is connected in segment 1. The AS-i power supply unit and slaves
must not be installed in segment 1. (Data decoupling required for the AS-i system is
integrated in the extender for segment 1.)
The AS-i power supply unit, the slaves, and any safety monitors are connected to
segment 2.
No electrical isolation of the two AS-i cable segments.
Segment 1 is automatically supplied from segment 2, whereby the current for segment 1
is restricted to 100 mA. For this reason, the extender can only be used in conjunction with
AS-i masters that are supplied via a separate voltage source. Extenders cannot be used
in conjunction with DP/AS-i Link20E because Link20E requires approx. 200 mA from the
AS-i cable. The same applies to other AS-i masters (e.g. DP/AS-i Link Advanced with
internal supply via AS-i).
Several extenders cannot be connected in series or in parallel.
A maximum of one extender and one repeater connected in series can be used if an AS-i
extension plug is not used.
When an AS-i extension plug is used (in segment 1 or/and segment 2), extenders and
repeaters must not be connected in series. If an AS-i extension plug is installed in
segment 1, it must be located near the AS-i master.
The extender is used, for example, where the AS-i master (in the cabinet) is installed far
away from the installation location of the slaves (machine configuration).
Setting the AS-i address
The extender is not assigned an AS-i address.

10.4.1 Overview
To exchange data with the master, all nodes must be addressed before they are integrated
in the AS-Interface network. This can be carried out:
Offline with an addressing unit
Online by the AS-Interface system master
The addresses are the values 1 to 31 (or 1A to 31A and 1B to 31B for the extended
AS-Interface Specification 2.1).
A new slave that has not yet been assigned its own address has the default address 0. It is
identified by the master as a new, non-addressed slave and, as such, does not yet take part
in standard communication.
Addresses can be assigned as required, that is, it does not matter whether the first slave is
assigned address 21 or 1, for example.

10.5 Analyzer
10.5.1 Overview
The AS-Interface analyzer is used for checking AS-Interface networks. This ensures that
faults can be identified systematically and facilitates continuous monitoring.
This device can help identify installation errors (e.g. insecure contacts or EMC faults with
extreme loads).
The user-friendly software allows users without specialist knowledge of AS-Interface to
assess the quality of entire networks. The AS-Interface analyzer also allows commissioning
and servicing tasks to be documented by creating test reports for the recordings performed.
Trigger functions allow expert AS-Interface users to carry out detailed diagnoses.
As a passive node, the AS-Interface analyzer "listens in" on communication in the
AS-Interface network. The device is also supplied from the AS-Interface cable.
The analyzer interprets the physical signals in the AS-Interface network and records
communication.
An RS232 interface is used to transfer the data acquired on a PC (e.g. notebook) where it
can be evaluated using the diagnostics software supplied.
Online statistics
This mode provides an overview of the existing AS-Interface system. The error rates for
each slave are represented in a traffic light format (green, amber, red).
The bus configuration and the slave data that is currently being transferred are clearly
displayed.
The extended statistics function can be used to determine the error rate as the number of
transferred or invalid bus telegrams.
The bundle error overview provides a graded overview of how many telegram repetitions
have occurred so that users can perform a targeted, predictive assessment of the transfer
quality.
Data mode
In this mode, the analyzer displays not only the digital input/output values but also the
current analog values as well as the input status of the safety slaves.
System accessories
10.5 Analyzer

Trace mode
This mode provides a comprehensive range of trigger functions as well as trace and view
filters in a similar format to that of the field bus analyzer.
An external trigger input and output round off the functional scope allowing even the most
complex errors to be located.
For troubleshooting in conjunction with safety monitor applications, status changes in the
code tables for safety slaves are detected and evaluated.
Test report
The recorded data of the online statistics can be easily output and documented via a test
report. Verification of the status of the plant for approvals or servicing tasks can then be
provided.
The measurement Wizard records the bus signals for a variable duration, thereby triggering
creation of an automatic test report. This allows the quality of AS-i plants to be checked
using standardized procedures.

10.6 Ground fault detection module
AS-Interface system
434 System Manual, 11/2008, 3RK2703-3BB02-1AA1
10.6 Ground fault detection module
10.6.1 Overview
"... Ground faults in control circuits must not cause machines to start unintentionally, cause
dangerous machine movements, or prevent machines from shutting down (EN 60204, part 1
or DIN VDE 0113)".
The AS-Interface ground fault detection module can be used to ensure that these
requirements are fulfilled. This SlimLine module reliably detects and reports ground faults in
AS-Interface systems.
The following ground faults are detected:
AS-i "+" ground fault
AS-i "-" ground fault
Ground faults in sensors and actuators supplied by the AS-Interface voltage.
One module for each AS-Interface network is sufficient.
Function
The ground fault is detected by the module, displayed via an LED, and signaled via two
signaling outputs (1. no ground fault / O.K.; 2. ground fault / fault). The ground fault signal is
stored in the module. Once the ground fault has been rectified (and not before), the module
can be reset by switching off the AS-Interface voltage, pressing the "Reset" button, or by
applying a high level at the floating remote reset input.
External auxiliary voltages are not monitored by this module with respect to ground faults.
Test / reset
Carry out regular checks to ensure that the module is functioning properly:
When you press the TEST/RESET button very briefly (< 2 s), this simulates a ground fault
and the FAULT output is set. This status remains until the system is reset with the
TEST/RESET button (> 2 s). This sets the OK output and resets the FAULT output. The
system cannot be reset when a ground fault is present.
The module can also be reset by means of a high level at the floating remote reset input
(R-RES). Again, the system cannot be reset when a ground fault is present.
The test function results in a ground fault. Switch the system to a safe state prior to the test.
Setting the AS-i address
The ground fault detection module is a passive module without IC and, therefore, does not
require its own address in the AS-Interface network.

10.6 Ground fault detection module
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 435
10.6.2 Checking for ground faults with a voltage measuring instrument
A ground fault anywhere in the AS-i cable can be detected using a high-resistance voltage
measuring instrument (Ri >= 20 MΩ, e.g. digital multimeter).
Procedure:
1. Set the measuring instrument to voltage measurement (V DC).
2. Connect the minus measuring lead to the system ground/ground.
3a. Connect the plus measuring lead to AS-i plus.
Without a ground fault, a voltage of approx. 15 V (+/- 3 V) is set. (Since the AS-i cable is
ideally only set via a capacitive voltage divider symmetrically with respect to system
ground, the measured voltage may drift slightly due to the internal resistance of the
measuring instrument.)
If a ground fault vis-à-vis AS-i plus occurs, the voltage can drop to as low as 0 V
(depending on the resistance in the ground connection).
If a ground fault vis-à-vis AS-i minus occurs, the voltage can increase to as much as the
maximum AS-i voltage (approx. 30 V, and depending on the resistance in the ground
connection).
Alternative:
3b. Connect the plus measuring lead to AS-i minus.
Without a ground fault, a negative voltage of approx. -15 V (+/- 3 V) is set. (Since the AS-i
cable is ideally only set via a capacitive voltage divider symmetrically with respect to
system ground, the measured voltage may drift slightly due to the internal resistance of
the measuring instrument.)
If a ground fault vis-à-vis AS-i plus occurs, the voltage can increase to as much as the
maximum AS-i voltage, that is, a negative voltage as low as approx. -30 V is measured
(depending on the resistance in the ground connection).
If a ground fault vis-à-vis AS-i minus occurs, the voltage can drop to as low as 0 V, that
is, a slight negative voltage about 0 V is measured (depending on the resistance in the
ground connection).
Note
Since the connected sensors are supplied by the AS-i voltage, a ground fault on the sensor
cable also causes a ground fault on the AS-i cable (with the exception of modules with
floating inputs).
If the outputs are supplied from the AS-i cable, the same applies to the actuator cables.
The cause of a ground fault could be anywhere in the AS-i network. Due to the flexibility of
the topology, no measurement procedure exists for automatically determining the location of
the fault.
System accessories
10.6 Ground fault detection module
AS-Interface system
436 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Tips for locating ground faults:
Are cables moved constantly?
Have any cables been driven over or otherwise damaged by vehicles (e.g. fork-lift
trucks)?
If possible, disconnect the AS-i cable segment by segment (AS-i plus and minus cable)
Disconnect neuralgic sensor cables one after the other or disconnect entire modules (and
connected sensors) one after the other from the AS-i cable (AS-i plus and minus cable).
Check whether – as described above – a ground fault exists using the voltage measuring
instrument.
Check the AS-i cable and sensor cables for insulation faults (chafing points, compression,
cuts, frayed litz wires at the terminals, even in prefabricated connectors, wet cable
connectors, etc.) and replace if necessary.
Make sure that all the cables are properly connected (AS-i cable and sensor cables; see
note above - must not be connected at any point to ground or external voltage).
Once the errors have been rectified, the ground fault detection module must be reset
(press the RESET/TEST button for ≥ 2 s or remote reset).

10.7 Overvoltage protection module
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 441
10.7 Overvoltage protection module
10.7.1 Overview
The AS-Interface overvoltage protection module protects downstream AS-Interface devices
or individual system sections in AS-Interface networks against mains-borne overvoltage that
can potentially be caused by switching operations or distant lightning strikes.
In the lightning protection zone concept, the overvoltage protection module is located at the
transition from zone 1 to 2/3. Direct lightning strikes must be handled by additional protective
measures at the transitions from lightning protection zone 0A to 1.
The AS-Interface overvoltage protection module can now also be used to integrate
AS-Interface in the overall overvoltage protection concept of a plant or machine.
The module has the same design and degree of protection (IP67) as the AS-Interface user
modules and is also connected in the same way. It is a passive module without AS-i IC and,
therefore, does not require its own address in the AS-Interface network.
It can be connected to an AS-Interface system via the FK-E or PG-E coupling module. The
EEMS interface can be used to protect the AS-Interface cable and auxiliary voltage cable
against overvoltage.
Overvoltage is discharged via a grounding cable with a green/yellow oil-resistant outer
sheath. This cable is fixed permanently in the module and must be connected with low
resistance to system ground.
Rated discharge current Isn
The rated discharge current is the peak value of a surge current with the wave form
8/20 microseconds for which the overvoltage protection module is rated in accordance with a
specific test program.
With the waveform 8/20, 100 % of the value is achieved after 8 microseconds and 50 % after
20 microseconds.
Protection level Up
The protection level of an overvoltage protection module is the maximum momentary value
of the voltage at the terminals as determined by means of individual tests.
The protection level characterizes the capability of an overvoltage protection module to limit
overvoltage to a residual level.
Accessories
An FK-E or PG-E coupling module is required for connecting the AS-Interface cable and the
auxiliary power supply cable.

10.8.1 AS-Interface shaped cable
10.8.1.1 Overview
The actuator-sensor interface, the networking system used for the lowest field range, is
characterized by the ease with which it can be assembled and installed. A new connection
system has been specially developed for AS-Interface,
whereby the network nodes are connected by the AS-Interface cable. This two-core cable
has a trapezoidal profile to protect against incorrect polarity.
Connections are established with the insulation displacement method, whereby contact pins
penetrate the shaped AS-Interface cable to provide secure contacting with the two cores.
The cables do not need to be cut or stripped. which means that AS-Interface nodes (e.g. I/O
modules, intelligent devices) can be connected in no time at all. The devices can also be
quickly and easily replaced.
To enable devices to be used in a wide range of different ambient conditions (e.g. in oily
areas), the AS-Interface cable is available in different materials (rubber, TPE, PUR).
A standard round cable is also available for special applications. With AS-Interface, data and
power for the sensors (e.g. BERO proximity switches) and actuators (e.g. indicator lights) are
transferred via the yellow AS-Interface cable.
The black AS-i cable can be used for actuators with a 24 V DC supply (e.g. solenoid valves).

System integration with Totally Integrated Automation
Totally Integrated Automation (TIA) is a one-stop, end-to-end, integrated solution platform
from Siemens. Networing covers everything from the plant control level and field/process
level through to the actuator/sensor level where AS-Interface is used.

Benefits of system integration
Totally Integrated Automation provides you with the technology you need to boost
productivity in automation, save time, cut costs, ensure and improve quality, and protect your
investments. You can leverage the benefits of TIA throughout the entire production lifecycle
of a plant or machine. The benefits of integrating AS-Interface are outlined below.
Benefits during configuration:
the seamless interaction of the software tools and standardized operating concept help
boost productivity in the configuration phase.
You can configure hardware and networks systematically in a graphical development
environment and parameterize the configuration using input dialogs. The bus
configuration can be changed without needing to access the user program. You no longer
have to spend time programming the interfaces. The software checks the configuration
data automatically to ensure that it is plausible and consistent.
Systematic data storage allows you to transfer variable changes automatically during
configuration and within the programs.
Benefits during installation and commissioning:
The distribution of plant communication across bus systems reduces the time and effort
involved in cabling and installation. Safety technology and standard modules used for
mixed operation can be connected to the same bus systems.
The configuration can be downloaded to the PLC, HMI, drives, and so on centrally. The
documentation for commissioning the plant components is archived in the configuration
environment.
Benefits during operation and maintenance:
During operation, you can monitor the modular plant components centrally. System-wide
communication can also take place across network boundaries.
Diagnostic and error messages are displayed in plain text and localize the fault or error in
the hardware or software. Downtimes due to maintenance are minimized. When you
replace modular components, the devices receive starting data from the CPU in RUN
mode too. New sensors (e.g. AS-i analog modules) adopt the parameters automatically.
You can use MMCs to transfer the entire configuration to a new CPU even without the
use of a PC / PG. The MMCs ensure that no data goes missing in the CPU during a
power failure.
Benefits for extending the production plant:
To optimize processes, simulation modules or software can be used in addition to
parameter settings and program changes. The modular and harmonized TIA system
concept allows plants to be easily extended not only during configuration but also when
the hardware is extended.

11.1.2 Integration of AS-i networks in SIMATIC
SIMATIC Technology is an integral part of Totally Integrated Automation. Connecting
AS-Interface to the higher-level controller via modules or routers allows you to leverage the
full range of benefits offered by TIA.
SIMATIC Manager is the starting point for all software tools. Engineering is carried out with
and in STEP 7, the SIMATIC configuration environment. Device-specific function modules
are either already available in STEP 7 or can be specially installed. The Distributed Safety
software package is available for safety applications.
PROFIBUS and Industrial Ethernet can be configured in a standardized graphical
development environment. Function modules can be parameterized in user-friendly dialogs.
Module libraries containing pre-programmed functions in STEP 7 are available for user
programs.
11.1.3 Integration in third-party controllers
PROFIBUS DP slaves and PROFINET IO devices can be integrated in the relevant networks
as standard DP slaves or standard IO devices using a GSD file. This allows open
communication right down to the operator control level. A GSD file (device master data file)
contains all the information required for communication between the CPU and AS-i master.
You can use the GSD file for the network integration of AS-i masters within a third-party
system.
The device-specific GSD files contain data for the PROFIBUS DP master and slave or the
PROFINET IO controller and device as well as general manufacturer specifications. These
files are provided by the manufacturers of PROFIBUS DP slaves and PROFINET IO
devices.
State-of-the-art configuration tools provide interfaces for the GSD data. The GSD file can
also be used for predecessor versions of STEP 7 that do comply with the device
requirements.
An example of integrating AS-Interface with a GSD file is described with STEP 7. The
configuration procedure and the contents of the dialogs are much the same for third-party
systems.

Figure 11-2 Communications principle for transferring binary data
The acyclic exchange of binary data via data blocks (DB 150) is also possible.
In the data area for binary data in the controller, the AS-i master occupies:
Max. 32 input and 32 output bytes with up to 62 A/B slaves assigned
Max. 16 input and 16 output bytes with up to 31 standard A/B slaves assigned
(for CP 343-2 P)
The start addresses of the input/output data depend on how the CPU is configured. When
configuration is carried out using STEP 7, digital output addresses must have the same start
value as the input addresses (system dependent). The arrangement of the I/O bits with
respect to the AS-i addresses also depends on the configuration. The following sort types
are only possible for routers:
CLASSIC
LINEAR (with STEP 7 configuration only)
Packed (with STEP 7 configuration only)

11.2.2 Safe binary data
Only DP/AS-i F-Link evaluates the input data of the ASIsafe slaves and transfers the
switching status (safety oriented) cyclically to the PROFIBUS DP master via PROFIsafe
telegrams. The safety program of the F-CPU assigns the safe data to the safe address
range. You can access the F I/Os in the same way as the standard I/Os via the process
image (PII). You cannot access the I/Os directly, however. The channels of an F I/O must
only be accessed from an F run-time group. Non-safe data from the ASIsafe slaves occupy
the same address space as binary AS-i slaves.

Figure 11-8 Communications principle for transferring safe data
The PROFIsafe message frame occupies the following lengths in the PROFIBUS DP
address space:
PIO 4 bytes (only PROFIsafe administration information)
PII 12 bytes (of which the first four 4 bytes are user data). The PII also contains safe
binary input data of the ASIsafe slaves (F-DI)
The start addresses of the safe input/output data depend on how the PROFIBUS DP master
is configured. When configuration is carried out with STEP 7, F-O addresses must have the
same start value as the F-I addresses (system dependent).

11.2.3 Analog data
AS-i analog data can be transferred by means of two access types:
Cyclic data exchange:
This data access type is available as an option with the STEP 7 configuration only.
The controller accesses the data of analog AS-i slaves directly in the cyclic process
image. The input or output data of analog AS-i slaves is mapped in a contiguous data
area in the controller.
The priority given to cyclic data exchange ensures that the process image is constantly
refreshed.
Acyclic data exchange:
Acyclic access to analog data via data blocks is supported with GSD and STEP 7
configuration. For this purpose, authorize write and read access to the analog data blocks
in your user program (e.g. SFC 58 / SFC 59). The transmitted analog value is always
consistent with regard to an AS-i slave. The data is transferred to the channels
sequentially.
You can save space in the address space in the CPU if you configure analog data
exchange using data blocks.

NOTICE
Restriction for AS-i slaves to profile 7.1 and 7.2
The following descriptions only apply to AS-i slaves that handle analog value transfer in
accordance with the AS-i slave profile 7.3, 7.4, 7.5.5, 7.A.5, B.A.5, 7.A.A, 7.A.8, 7.A.9, and
6.0 (Combined Transaction Types CTT 1 to 5 in accordance with AS-i Specification V3.0).
AS-i masters do not support analog value transfer in accordance with the AS-i slave profile
7.1 / 7.2. In this case, analog data can be transferred via a user program.
Analog addresses
With STEP 7 configuration, up to 31 AS-i addresses can be assigned to analog slaves.
AS-i masters to Specification 3.0 also support up to 62 analog A / B slaves in the extended
address space. Up to 8 bytes of data are available for each address. You can configure a
maximum of four analog channels for each AS-i address, which all originate from an analog
AS-i slave. A total of 240 bytes are available for the process data.
For the start area, see the analog data in the configuration.
Figure 11-11 Assignment of the analog data
For example, the AS-i slave with address 1A occupies bytes 256 to 259 in the analog input
data area in the controller.

m + 3 Channel 2 / low byte
m + 4 Channel 3 / high byte
m + 5 Channel 3 / low byte
m + 6 Channel 4 / high byte
m + 7 Channel 4 / low byte
Analog A / B slaves only occupy "half an address", which is why they only have a maximum
of 2 channels. A slaves occupy bytes 0 to 3 and B slaves bytes 4 to 7.
Note
Representation of the analog values or the transparent values
The analog values are arranged as 16-bit values in the two's complement.
The transparent values must be interpreted as two independent bytes.
With SIMATIC S7 as the CPU, AS-i analog values are accessed with word commands.
Example:
If you have configured an AS-i slave "2AI" with input address 256, you can use the STEP 7
command "L PEW 258" to access the second analog channel of the slave.
Data blocks for analog value transfer
Authorize the commands read_data_block and write_data_block as described in the
AS-i master manuals. The data blocks can be used for the analog input and analog output
area.
DP/AS-i LINK Advanced and DP/AS-Interface LINK 20E:
To access analog values, choose one of the data blocks from 140 to 147.
The data blocks have different lengths. Each data block is assigned a contiguous address
space of AS-i slaves. If you operate fewer analog AS-i slaves than the AS-i master
supports, optimize the reserved data area in your application program by making the
appropriate selection. For each AS-i address, the data blocks contain one block of
8 bytes of data. The arrangement of the analog data within this data block corresponds to
that in the cyclic process image.
DP/AS-i F-Link:
The following data blocks are also available:
DB 151: Analog image of the output data for AS-i slaves 1 ... 29
DB 152: Analog image of the input data for AS-i slaves 1 ... 29
DB 153: Analog image of the output data for AS-i slaves 3 ... 31

11.3.4 Parameterizing AS-Interface
Parameterize the properties and behavior of the CP 343-2 as an AS-i master in the
"Properties - CP 343-2 -..." dialog.
Step Action
1 Double-click the slot for the CP 343-2.
A window is displayed containing the "Properties - CP 343-2 -..." dialog, which contains the "General" and
"Addresses" tabs.
2 If required, enter the name and a comment for the AS-i line on the "General" tab.
To configure the binary I/O address spaces for the AS-i slaves, choose the "Addresses" tab.
In the analog address space of the S7-300 CPU, the CP 343-2 occupies 16 bytes for binary data. This memory
is available to standard and A slaves. To enable bit-serial access, you first have to transfer the input data to
certain words (data, flags). Data can be accessed by means of load and transfer commands. Depending on the
system, even byte addresses can only be accessed with word or double-word commands.
E.g.:
L PEW 256 // load I/O input word
T PAD 258 // transfer I/O output double word
Move the output data from the words (data, flags) to the analog address space.
You can access binary I/O data of B slaves via data block 150.
3.1 Set the I/O address for the binary input data or accept the value displayed. If you enter an invalid
address, the system proposes a new one.
Input addresses relate to a max. 16-byte memory area in which the input values of the AS-i slaves are
stored (standard and A slaves).
For the digital output addresses, the same starting value as for the input addresses applies depending
on the system.
3
3.2 If the "Process image" drop-down list contains the entry "- - -", this means that no process image is
available for the specified address space.
If you plan to access data in the area of the process images and the CPU allows the address space to
be shifted, choose a lower input address.
The process image can be used to access I/O data with individual bit commands.

11.3.7 Addressing AS-i slaves
Address the AS-i slaves in accordance with the configuration.
Step Action
1 If the addresses of the AS-i slaves do not match the configuration, the CER and SF LEDs light up.
Address the AS-i slaves in one of the following ways:
With an addressing unit
With a STEP 7 user program using the "Change_AS-i_slave_address" command in the command interface
11.3.8 Saving the configuration
In "configuration" mode, the CP 343-2 exchanges data with all the connected AS-i slaves.
The CP 343-2 instantly recognizes new AS-i slaves, activates them, and includes them in
cyclic data exchange (except AS-i slaves with the address "0" or if an AS-i address has been
assigned more than once). The CP 343-2 saves the following AS-i slave data to a
non-volatile memory:
Addresses
ID codes
I/O configuration
Note
Button configuration on the device when the CPU is in "STOP" mode only
Before saving the AS-i configuration, you must ensure that no communication is taking
place with the CPU. If necessary, switch the CPU to "STOP" mode.

11.4.4 Parameterizing AS-Interface
Parameterize the properties and behavior of the CP 343-2P as an AS-i master in the
"Properties - CP 343-2 P -..." dialog.
Step Action
1 Double-click the slot for the CP 343-2P.
A window is displayed containing the "Properties - CP 343-2 P -..." dialog, which contains the "General",
"Addresses", "Operating Parameters", "Slave Configuration", and "AS-i Slave options" tabs.
2 If required, enter the name and a comment for the AS-i line on the "General" tab.
To configure the binary I/O address spaces for the AS-i slaves, choose the "Addresses" tab.
In the analog address space of the S7-300, the CP 343-2P occupies 16 bytes for binary data. This memory is
available to standard and A slaves. To enable bit-serial access, you first have to transfer the input data to
certain words (data, flags). Data can be accessed by means of load and transfer commands. Depending on the
system, even byte addresses can only be accessed with word or double-word commands.
E.g.:
L PEW 256 // load I/O input word
T PAD 258 // transfer I/O output double word
Move the output data from the words (data, flags) to the analog address space.
You can access binary I/O data of B slaves via data block 150.
3.1 Set the I/O address for the binary input data or accept the displayed value. If you enter an invalid
address, the system proposes a new one.
Input addresses relate to a max. 16 byte memory area in which the input values of the AS-i slaves are
stored (standard and A slaves).
For the digital output addresses, the same starting value as for the input addresses applies depending
on the system.
3
3.2 If the "Process image" drop-down list contains the entry "- - -", this means that no process image is
available for the specified address space.
If you plan to access data in the area of the process images and the CPU allows the address space to
be shifted, choose a lower input address.
The process image can be used to access I/O data with individual bit commands.

3.3 If the "Process image" drop-down list contains selection data, this means that the PROFIBUS DP
master is a CPU that manages partial process images (e.g. CPU 416). Choose a partial process image
number (PPI no.) or the OB1 process image for cyclic updates.
On the "Operating Parameters" tab, set the behavior of the CP 343-2P as an AS-i master.
4.1 Activate the alarm enable for diagnostic interrupts (OB82).
Diagnostic interrupts are triggered if the following faults occur:
Group fault (SF)
Internal fault (= device fault)
External fault (e.g. AS-i slave failed)
At least one AS-i slave does not match the target specification.
Voltage on AS-i bus too low (AS-i Power Fail, APF)
Hardware fault (internal watchdog)
EEPROM defective
4
4.2 Choose the option for automatic address programming.
When you choose the option "Automatic address programming" (default), an AS-i slave that has failed
can be replaced by a new, identical slave with the address "0" (as-delivered state). The CP 343-2P
automatically assigns the new slave the address of the old one.
If this option is deactivated, you have to program the address into the new slave when the slave is
replaced.

Step Action
3.1 Set the I/O address for the binary input data or accept the displayed value. If you enter an invalid
address, the system proposes a new one.
Digital input addresses relate to a max. 32 byte memory area in which the binary input values of the
AS-i slaves are stored.
For the digital output addresses, the same starting value as for the input addresses applies depending
on the system.
3.2 If you use the CLASSIC sort type for the I/O addresses (default setting), you can set the "Reserved
lengths" value.
You can use this parameter to suppress unassigned I/O addresses at the lower end of the table or fix an
associated address space for future extensions on AS-Interface.
The "Assigned length" shows the amount of memory currently occupied by the AS-i slaves in bytes.
3.3 If the "Process image" drop-down list contains selection data, this means that the PROFIBUS DP
master is a CPU that manages partial process images (e.g. CPU 416).
Choose a partial process image number (PPI no.) or the OB1 process image for cyclic updates.
3.4 Choose a sort type for the I/O addresses of the AS-i slaves (default: "CLASSIC").
The "Pack" button moves the I/O addresses of the AS-i modules in the AS-i address table in such a way
that they require less room in the address space. In addition, the "Reserved length" is optimized.
The "CLASSIC sorting" pushbutton sorts the I/O addresses according to AS-i address. The
standard / A slaves are at the beginning, followed by the B slaves.
The "LINEAR sorting" pushbutton sorts the I/O addresses in ascending order. Standard / A slaves and
B slaves with the same AS-i address are combined in one byte (standard / A slave in the low nibble,
B slave in the high nibble).

11.8.6 Parameterizing the binary address space
Assign the binary AS-i slaves an address space via the slot assignment in the station
window.
Step Action
1 Note the following assignment with the drag & drop slot assignment from the hardware catalog:
Choose just one ASi-1 module for a single master or line 1 of a double master.
Choose ASi-2 modules for line 2 of a double master.
2 Position just one binary module for each AS-i line.
The following binary modules are available:
"Binary Array 32 Byte" allows A/B slaves to be used that are set to B addresses. In this case, the entire
binary data interface of DP/AS-i LINK Advanced can be used.
"Binary Array 16 Byte" allows a maximum configuration with 31 standard AS-i slaves. B slaves cannot be
used.
With "Binary Array 8 Byte", you reserve a reduced memory space. Only standard AS-i slaves with the
addresses 1 ... 15 can be used, however.
The universal module cannot be used.
You are advised to assign an "ASi-1" binary module to slot 1. For a double master, assign an "ASi-2" binary
module to slot 2.

The "F_Source_Add" parameter uniquely identifies the PROFIsafe source (PROFIBUS DP Master). The
system assigns this parameter automatically. The value range is from 1 to 65534.
2.6 Parameter "F_Dest_Add"
The "F_Dest_Add" parameter uniquely identifies the PROFIsafe target (DP/AS-i F-Link). The parameter
is unique across the network and stations. The value range for "F_Dest_Add" is from 1 to 9999. This
address must match the F-DP (PROFIsafe address) that you set on the device.
2.7 Parameter "F_WD_Time"
In the "F_WD_Time" field, you can set the monitoring time for safety-oriented communication between
the failsafe CPU and failsafe I/O.
DP/AS-i F-Link expects a valid safety message frame from the failsafe CPU within the monitoring time.
As a result, DP/AS-i F-Link can safely respond to failures and errors by either keeping the system in
safe mode or by switching it to a safe mode.
When you choose the monitoring time, make sure that, on the one hand, it is long enough to ensure that
telegram delays caused by communication are tolerated while, on the other hand, the system can still
respond in good time if an error occurs (e.g. interruption of communication connection).
The "F_WD_Time" parameter can be set to anywhere between 10 ms and 10000 ms in 1 ms increments
(default: 150 ms).
3 On the "F Addresses" tab, set the I/O address of the safe input data or accept the value displayed. If you enter
an invalid address, the system proposes a new one.
The safe input data requires 12 bytes of memory space. The end address appears automatically.
Depending on the system, the I/O addresses of the safe outputs match the I/O addresses of the safe inputs.
The process image of safe outputs has a fixed length of 4 bytes and only contains administrative data, but no
user data.

11.9.6 Parameterizing AS-Interface
Parameterize the properties and behavior of DP/AS-i F-Link as an AS-i master in the
"Properties - DP/AS-i -..." dialog.
Step Action
1 In the AS-i address table, double-click the second line with the "DP/AS-i" module.
A window is displayed containing the "Properties - DP/AS-i - ..." dialog, which contains "General",
"Digital Addresses", "Operating Parameters", and "AS-i Slave Options" tabs.
2 If required, enter the name and a comment for the AS-i line on the "General" tab.
To configure the binary I/O address spaces for the AS-i slaves, choose the "Digital Addresses" tab.
3.1 Set the I/O address for the binary input data or accept the displayed value. If you enter an invalid
address, the system proposes a new one.
Digital input addresses relate to a max. 32 byte memory area in which the binary input values of the
AS-i slaves are stored.
For the digital output addresses, the same starting value as for the input addresses applies depending
on the system.
3.2 If you use the CLASSIC sort type for the I/O addresses (default setting), you can set the
"Reserved lengths" value.
You can use this parameter to suppress unassigned I/O addresses at the lower end of the table or fix an
associated address space for future extensions on AS-Interface.
The "Assigned length" shows the amount of memory currently occupied by the AS-i slaves in bytes.
3
3.3 If the "Process Image" drop-down list contains selection data, this means that the PROFIBUS DP
master is a CPU that manages partial process images (e.g. CPU 416F).
Choose a partial process image number (PPI no.) or the OB1 process image for cyclic updates.

Step Action
3.4 Choose a sort type for the I/O addresses of the AS-i slaves (default: "CLASSIC").
The "Pack" button moves the I/O addresses of the AS-i modules in the AS-i address table in such a way
that they require less room in the address space. In addition, the "Reserved length" is optimized.
The "CLASSIC sorting" pushbutton sorts the I/O addresses according to AS-i address. The
standard / A slaves are at the beginning, followed by the B slaves.
The "LINEAR sorting" pushbutton sorts the I/O addresses in ascending order. Standard / A slaves and
B slaves with the same AS-i address are combined in one byte (standard / A slave in the low nibble,
B slave in the high nibble).
On the "Operating Parameters" tab, set the behavior of DP/AS-i F-Link as an AS-i master. 4
4.1 Activate the alarm enable for diagnostic interrupts (OB82).
Diagnostic interrupts are triggered if the following faults occur:
Code sequence error
Group fault (SF)
Internal fault (= device fault)
External fault (e.g. AS-i slave failed)
At least one AS-i slave does not match the target specification.
Voltage on AS-i bus too low (AS-i Power Fail, APF)
Hardware fault (internal watchdog)
EEPROM defective

Step Action
4.2 Choose the options for the behavior of DP/AS-i F-Link when PROFIBUS fails and is then restored.
If PROFIBUS fails (BUS fault), DP/AS-i F-Link continues running as the AS-i master. The inputs are
interrogated cyclically, but the outputs shut down.
When the PROFIBUS is restored, DP/AS-i F-Link is supplied with the start-up parameters again and
switches to protected mode.
When you activate the "AS-i reset on PROFIBUS return" option, a PROFIBUS restart always resets
AS-Interface. The receipt of message frames for parameterization and configuration data from the
PROFIBUS DP master causes AS-i message frame traffic to stop completely and then restart.
Upon deactivation (default), DP/AS-i F-Link checks the discrepancies between the data in the
parameterization and configuration message frame and the actual data when the PROFIBUS restarts.
The comparison is used as a basis for the following responses:
If all the data is identical, no reset is performed on AS-Interface.
If certain parameter bits of the AS-i slaves are not identical, just these ones are updated.
If any other discrepancies are identified, a reset is performed on AS-Interface.
When you choose the option "Automatic AS-i address assignment" (default), an AS-i slave that has
failed can be replaced by a new, identical slave with the address "0" (as-delivered state). DP/AS-i F-Link
automatically assigns the new slave the address of the old one.
If this option is deactivated, you have to program the address into the new slave when the slave is
replaced.

Select an AS-i slave via the context menu "Insert Object..."
Path: V1.0 > AS-i F slave or AS-i slave
Copy and insert via the clipboard.
Move the line content by pressing down the left mouse button.
A configured slave changes its AS-i address as a result.
3 Note the following rules for assigning addresses:
The lines containing potential target addresses are highlighted in green.
Standard slaves, ASIsafe slaves, and certain analog slaves use a full AS-i address (A and B address line).
Some AS-i slaves (e.g. CTT5) require the following full addresses, depending on whether the slaves are of
type 2, 3, or 4. Make sure that the following addresses remain free.

Parameterize the AS-i slaves.
3.1 If the selected Siemens modules support special parameter settings, you can select them from a range
of drop-down lists.
The bit checkboxes cannot be changed separately. Their assignment is predefined by the modules or
results from the entries in the adjacent fields.
3
3.2 If the AS-i slaves are not available for selection, set the parameter bits in accordance with the
manufacturer guidelines.
With an A/B module, the checkbox for parameter bit 3 is not displayed.
4 If you activate the "Reserve max. address space" checkbox, the system makes the 4-bit input addresses and
4-bit output addresses available for the AS-i slave in the I/O memory.
The system displays an input and output address range for digital data exchange. If a digital AS-i slave has not
been assigned any inputs or outputs, the corresponding field is empty.
5 If you intend to transfer analog data for an analog AS-i slave via cyclic PROFIBUS DP services, activate the
appropriate option. Otherwise, analog data can only be transferred via data blocks.
The system proposes an input and output address space. The values can be changed. The system reports
incorrect values.
6 If required, enter the name and a comment for an AS-i slave on the "General" tab. When you close the dialog,
your entries appear in the AS-i address table.
7 If you enter safety-oriented parameters for ASIsafe slaves on the "ASIsafe" tab, continue with the configuration
procedure described in the next section "Parameterizing ASIsafe slaves".

11.9.9 Parameterizing ASIsafe slaves
Parameterize the safety settings of ASIsafe slaves on the "ASIsafe" tab.
Step Action
1 Call up the "ASIsafe" tab in the "Properties - AS-i F-Slave" dialog.
The folder structure for the safety parameters is opened. In the "Value" column, variable parameters are
highlighted in white.
2 Activate the "Activated" checkbox so that the ASIsafe slave is enabled for signal processing in the safety
program.
If you do not do this, the ASIsafe slave is deactivated from a safety point of view in DP/AS-i F-Link and none of
the other parameters can be edited.
It may need to be deactivated, for example, for an ASIsafe slave that is assigned to an additional safety
monitor in AS-Interface.
3 To suppress coupled-in interference, you can set a module-wide input delay for an ASIsafe slave.
This suppresses burst interference from 0 ms to 150 ms The input delay can be subject to a tolerance value.
Refer to the operating instructions of the failsafe modules. A long input delay will suppress longer interference
pulses; a short input delay will suppress shorter interference pulses. The default value is 0 ms.
The input delay has a cumulative effect on the system response time.
4 Choose one of the following options for evaluating the sensors:
For the "1v1 evaluation", the sensor exists once and is connected on one channel to the first input of the
ASIsafe slave. To do so, jumper the second input of the ASIsafe slave. Instead of the jumper, you can also
connect a second single-channel sensor to the second input. DP/AS-i F-Link does not forward a resulting
ON signal to the PLC until both inputs return ON signals.
For the "2v2 evaluation", both inputs on the ASIsafe slave are occupied by a two-channel sensor or by two
one-channel sensors. Functionally, the two single-channel sensors belong together as a pair.

11.9 DP/AS-i F-Link - integration with STEP 7
AS-Interface system
544 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Step Action
5 If you have set a 2v2 sensor evaluation, choose a parameter for discrepancy fault suppression.
If you use one two-channel or two one-channel sensors that acquire the same physical process variables, the
sensors address each other with a delay. This delay results from the sensor arrangement or the limited
accuracy.
The discrepancy analysis examines the variation over time of two failsafe input signals with the same
functionality. The discrepancy analysis starts as soon as the system identifies a discrepancy.
The following conditions are available:
No discrepancy error suppression (default)
The discrepancy analysis starts as soon as different signals are present on channels 1 and 2.
Discrepancy fault suppression "For 0 signal at channel 1"
The discrepancy analysis starts as soon as a 1 signal is present on channel 1 and a 0 signal is present on
channel 2.
Discrepancy fault suppression "For 0 signal at channel 2"
The discrepancy analysis starts as soon as a 1 signal is present on channel 2 and a 0 signal is present on
channel 1.
During the module-internal expiration of the parameterized discrepancy time, the value "0" for the affected
ASIsafe slaves is made available to the safety program in the F-CPU. If the discrepancy remains even after the
parameterizable discrepancy time has elapsed, a discrepancy error is present and a diagnostic interrupt is
triggered.
6 If you have set a 2v2 sensor evaluation, enter a parameter for the discrepancy time.
When you choose a discrepancy time for a channel pair, make sure that it is long enough for the difference
between the two signals to disappear before the discrepancy time has elapsed. The values are within the range
100 ms (default) to 2500 ms with an increment of 10 ms.

DP/AS-i F-Link only starts when the following modules have been created:
OB 82, diagnostic interrupt
OB 85, program execution error
OB 86, rack failure of failure of a station in distributed I/O
Call up the safety program with F-CALL from an OB.
The benefit of F-CALLs from a time interrupt OB (e.g. OB 35) is that they interrupt cyclic
program processing in the OB 1 at fixed intervals.
Once the safety program has been processed, the system returns to the standard user
program.
When programming and commissioning safety technology, note the special regulations
regarding the plant acceptance inspection.

Parameterize DP/AS-i F-Link as a PROFIBUS DP slave in HW Config of the PROFIBUS DP
master.
Step Action
1 Double-click the DP/AS-i F-Link icon on the DP master system.
A window is displayed containing the "Properties - DP Slave" dialog, which contains the "General" and
"Parameterization" tabs.
On the "General" tab, set the properties of DP/AS-i F-Link as a node on the PROFIBUS DP.
2.1 Enter the diagnostics address or use the system proposal. If you enter an invalid address, the system
proposes a new one.
The PROFIBUS DP master uses the diagnostics address to find out about a failure or return of a
PROFIBUS DP slave and starts the OB 86. You can also call up the full diagnosis of the slave under
this address with SFC 13 DPNRM_DG and include it in your user program.
2
2.2 Activate response monitoring so that DP/AS-i F-Link can respond to errors in the PROFIBUS DP master
or if bus data traffic is interrupted.
If the PROFIBUS DP master does not address DP/AS-i F-Link within the configured monitoring time, the
PROFIBUS DP slave switches to safe mode and sets all the outputs to "0".

11.10.5 Parameterizing AS-Interface
Parameterize the properties and behavior of DP/AS-i F-Link as a PROFIBUS DP slave and
AS-i Master on the "Parameterization" tab.
Step Action
1 Call up the "Parameterize" tab in the "Properties - DP-Slave" dialog.
2 In the relevant option box, activate the alarm enable for diagnostic interrupts (OB82).
Diagnostic interrupts are triggered if the following faults occur:
Code sequence error
Group fault (SF)
Internal fault (= device fault)
External fault (e.g. AS-i slave failed)
At least one AS-i slave does not match the target specification.
Voltage on AS-i bus too low (AS-i Power Fail, APF)
Hardware fault (internal watchdog)
EEPROM defective
The DP/AS-i F-Link firmware does not support or generate any process alarms, even though the parameter
can be selected.
3 When you change the operating mode of the PROFIBUS DP master from DPV1 to DPV0, you first have to
deactivate the options for the diagnostic and process interrupts.
Then choose the operating mode from the "DP alarm mode" drop-down list.

Step Action
4 When you activate the "AS-i Reset at PROFIBUS Restore", a PROFIBUS restart always resets AS-Interface.
The receipt of telegrams for parameterization and configuration data from the PROFIBUS DP master causes
the AS-i telegram traffic to stop completely and then restart.
If this option is deactivated (default), DP/AS-i F-Link checks the discrepancies between the data in the
parameterization and configuration telegram and the actual data when the PROFIBUS restarts. The
comparison is used as a basis for the following responses:
If identical, DP/AS-i F-Link does not reset AS-Interface.
If certain parameter bits of the AS-i slaves are not identical, just these ones are updated.
If any other discrepancies are identified, a reset is performed on the AS-Interface.
5 When the "Automatic AS-i addressing" is active (default), an AS-i slave that has failed can be replaced by a
new, identical slave (same IO, ID, ID1, and ID2 code) with the address "0" (on delivery). DP/AS-i F-Link
automatically assigns the new slave the address of the old one.
6 Use only the parameters described above to make changes to the parameterization telegram. To prevent any
unforeseen events, do not change any values in the "Hex parameterization" folder.
11.10.6 Parameterizing ASIsafe slaves
Configure the ASIsafe slaves via:
The "Properties - DP Slave" dialog for slot 4 with the designation "F-Link(PROFIsafe)".
The AS-i addresses to which certain parameters are assigned.
Step Action
1 Double-click line 4 in the configuration table with the description "F-Link(PROFIsafe)".
A window is displayed containing the "Properties - DP Slave" dialog, which contains the "Address / ID",
"Parameterization" tabs, and "PROFIsafe" tabs.
2 On this tab, set the I/O address of the safe output data or accept the system proposal.
The safe output data requires 4 bytes of memory space and only contains administration information, no user
data. The system calculates the end address and signals any errors that occur.

AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 555
Step Action
3 Set the I/O address for the safe input data or accept the system proposal.
If the start addresses change, note that the start addresses for safe inputs and outputs must be identical. The
safe input data require 12 bytes of memory space. The system calculates the end addresses and signals any
errors that occur.
3 Note that the safety-oriented parameters of ASIsafe slaves are defined via their AS-i addresses. This
assignment is important for setting the device-specific parameters and for assigning addresses during
commissioning.
A maximum of 31 ASIsafe slaves can be connected on DP/AS-i F-Link. When configuration is carried out with
the GSD file, the functional scope for the safety-oriented evaluation is predefined.
The following applies to all ASIsafe slaves:
Input delay: 0 ms
By placing the ASIsafe slave in a specific address range, you decide about the evaluation of the following input
signals:
AS-i addresses 1 ... 16
Encoder evaluation: 1v1 evaluation
AS-i addresses 17 ... 31
Encoder evaluation: 1v1 evaluation
Type of encoder interconnection: 2-channel (equivalent)
Discrepancy time: 2500 ms
No discrepancy error suppression
Reintegration after discrepancy error: test 0 signal required on both channels
Note the explanations about the safety-oriented parameters in the relevant section Paremeterizing ASIsafe
slaves (Page 543) of the STEP 7 configuration.
4 Note that you cannot make any changes on the "Parameter Assignment" tab.

11.10.7 Parameterizing PROFIsafe communication
Parameterize PROFIsafe communication of DP/AS-i F-Link on the "PROFIsafe" tab.
NOTICE
Setting for the parameter "F_Par_Version"
If the network comprises PROFIBUS DP and PROFINET IO subnets, set "PROFIsafe V2".
Step Action
1 Enter the password for the safety program.
When you access the PROFIsafe parameters in DP/AS-i F-Link for the first time, STEP 7 prompts you to create
a new password.
You must enter a password if you want to make any changes to the PROFIsafe settings. The last password
entered is valid for one hour. Subsequent password changes can be made in the SIMATIC Manager > menu:
"Tools" > "Edit Safety Program" dialog > "Authorization" pushbutton.
On the "PROFIsafe" tab, set the safety-oriented parameters for DP/AS-i F-Link for the PROFIsafe protocol.
Change the parameter values by double-clicking the parameter name or by choosing "Change value...".
2.1 Parameter "F_Check_SeqNr":
This parameter defines whether the consistency check (CRC calculation) of the failsafe user data
telegram takes into account the sequence number.
In PROFIsafe V1 mode, this parameter is set permanently to "No Check".
In PROFIsafe V2 mode, "F_Check_SeqNr" is irrelevant.
Note here the setting of the PROFIsafe mode in the parameter "F_Par_Version".
2
2.2 Parameter "F_SIL":
this "F_SIL" indicates the safety class of DP/AS-i F-Link and cannot be changed.

2.3 Parameter "F_CRC_Length"
set the following for the "F_CRC_Length" parameter:
In PROFIsafe V1 mode: "2 Byte CRC"
In PROFIsafe V2 mode: "3 Byte CRC" (default)
Note here the setting of the PROFIsafe mode in the parameter "F_Par_Version".
2.4 Parameter "F_Par_Version"
the following selection can be made:
"PROFIsafe V1": If the F CPU only supports PROFIsafe V1, choose this setting.
"PROFIsafe V2" (default)
If the network comprises PROFIBUS DP and PROFINET IO subnets, set "PROFIsafe V2".
2.5 Parameter "F_Source_Add"
the "F_Source_Add" parameter uniquely identifies the PROFIsafe source (PROFIBUS DP-Master). The
system assigns this parameter automatically. The value range is from 1 to 65534.
2.6 Parameter "F_Dest_Add"
the "F_Dest_Add" parameter uniquely identifies the PROFIsafe target (DP/AS-i F-Link). The parameter
is unique across the network and stations. The value range for "F_Dest_Add" is from 1 to 9999. This
address must match the F DP (PROFIsafe address) that you set on the device.
2.7 Parameter "F_WD_Time":
in the "F_WD_Time" field, you can set the monitoring time for safety-oriented communication between
the failsafe CPU and failsafe I/O.
DP/AS-i F-Link expects a valid safety telegram from the CPU within the monitoring time. As a result,
DP/AS-i F-Link can safely respond to failures and errors by either keeping the system in safe mode or
by switching it to a safe mode.
When you choose the monitoring time, make sure that, on the one hand, it is long enough to ensure that
telegram delays caused by communication are tolerated while, on the other hand, the system can still
respond in good time if an error occurs (e.g. interruption of communication connection).
The "F_WD_Time" parameter can be set to anywhere between 10 ms and 10000 ms in 1 ms increments
(default: 150 ms).

2 On this tab, set the I/O address of the binary output data or accept the system proposal.
Depending on the selected module, the system calculates the end address and signals any errors that occur.
When configuration is carried out using the GSD file, the I/O data of the AS-i slaves are arranged in the
CLASSIC sorting.
3 Set the I/O address for the binary input data or accept the system proposal.
Depending on the selected module, the system calculates the end address and signals any errors that occur.
4 If the "Process Image" drop-down list contains selection data, this means that the PROFIBUS DP master is a
CPU that manages partial process images (e.g. CPU 416F).
Choose a partial process image number (PPI no.) or the OB1 process image for cyclic updates.
5 Choose the "Parameterization" tab.

11.10.18 Information about the user program
When creating the user program, note the following information:
DP/AS-i F-Link only starts when the following modules have been created:
OB 82, diagnostic interrupt
OB 85, program execution error
OB 86, rack failure of failure of a station in distributed I/O
Call up the safety program with F-CALL from an OB.
The benefit of F-CALLs from a time interrupt OB (e.g. OB 35) is that they interrupt cyclic
program processing in the OB 1 at fixed intervals.
Once the safety program has been processed, the system returns to the standard user
program.
When programming and commissioning safety technology, note the special regulations
regarding the plant acceptance inspection.

11.11.3 Configuring the PROFINET IO system
Configure IE/AS-i LINK PN IO as a modular IO device in HW Config of the PROFINET IO
controller.
Step Action
1 Open your STEP 7 project with a SIMATIC S7-CPU with the PROFINET IO controller (e.g. CPU 315-2 PN/DP).
Whenever possible, always use the latest firmware version on the CPU and IE/AS-i LINK PN IO to leverage the
complete functionality.
2 Open HW Config for the PROFINET IO controller.
3 If the PROFINET IO system is not yet available on the CPU, you have to create it.
To do so, insert the PRIFINET IO system in slot X2 (PN-IO) of the CPU (e.g. via the "Insert PROFINET IO
system" context menu (right click)).
4 Select the IE/AS-i LINK PN IO in the "Hardware Catalog" window.
Path: PROFINET IO > Router > IE/AS-i Link PN IO > 6GK1411-2AB10 > V2.0 (or as double master

11.11.4 Parameterizing the IE/AS-i LINK PN IO as an IO device
Parameterize IE/AS-i LINK PN IO as an IO device in HW Config of the IO controller.
Step Action
Parameterize the diagnosis address in the "Properties - IE-ASi-Link" dialog for slot "0".
1.1 Double-click the icon for IE/AS-i LINK PN IO on the IO system.
A window is displayed containing the "Properties - IE/AS i Link ..." dialog, which contains the "General",
"IO Cycle", and "Diagnostics" tab pages.
1.2 On the "General" tab, set the properties of IE/AS-i LINK PN IO as a node on the IO system.
1.3 Enter a device name of use the system proposal.
When it is shipped, an IO device does not have a device name. An IO controller cannot address an IO
device until it has been assigned a device name. The IP address is assigned permanently to the device
name. Unlike the complex IP addresses, device names are much more user friendly. The process of
assigning a name for an individual IO device is similar to that for setting the PROFIBUS address for a
PROFIBUS DP slave.
1.4 Choose a device number from the drop-down list or use the system proposal.
In addition to the device name, STEP 7 assigns a device number when an IO device is connected.
This device number is used to identify an IO device in the user program.
Unlike the device number, the device name is not visible in the user program.
1
1.5 For an isolated Ethernet subnet, use the IP address and subnet mask proposed by STEP 7.
If the subnet is part an existing Ethernet company network, ask your network administrator for this data.
Open the "Properties - Ethernet Interface IE ASi Link" dialog by choosing "Ethernet..." and enter the
network data.
Define the properties of the PN IO interface. 2
2.1 Double-click the line "X1" in the AS-i address table.
A window is displayed containing the "Properties - PN-IO" dialog, which contains the "General",
"Addresses", and "IO Cycle" tab pages.
The name "PN-IO" can be changed on the "General" tab page.

Step Action
2.2 Select the "IO Cycle" tab page.
2.3 In the "IO Cycle" tab, choose the updating time for an individual IO device.
During the updating time, a PROFINET IO device exchanges its user data with the associated IO
controller. STEP 7 automatically calculates updating times from the existing hardware configuration and
the resulting cyclic data. The updating time applies to either an entire bus segment of an IO controller or
just to one IO device. The shortest possible updating time in a PROFINET system depends on the
following factors:
No. of PROFINET IO devices
Volume of configured user data
PROFINET IO communication share (compared with the PROFINET CBA communication share)
Additional cyclic PROFINET services
Properties (performance) of the IO controller
If you increase the updating times of individual IO device that supply user data (non-time-critical),
shorter updating times can be set for other IO devices.
If you change the hardware configuration (e.g. add new IO devices), the updating time may change. A
change message appears the next time you open the dialog.
2.4 Configure the response monitoring time.
The response monitoring time cannot be set directly but instead as a "No. of accepted updating times
with missing IO data". Multiplying the updating time results in the response monitoring time.
If the IO controller does not supply the IO device with I/O data within the response monitoring time, the
IO device switches to safe mode.
Only change the default setting in an emergency (e.g. during the commissioning phase).

11.11.5 Parameterizing AS-Interface
Parameterize the properties and behavior of IE/AS-i LINK PN IO as an AS-i master in the
"Properties - IE/AS-i ..." dialog.
Step Action
1 Double-click the line "[1]" in the AS-i address table.
A window is displayed containing the "Properties - IE-ASi-Link-1M" (for single master) or "Properties -
IE-ASi-Link-2M" (for double master), which contains the "General", "Addresses", and "Pack" tab pages.
The following settings relate to IE-AS-i LINK PN IO as a single master or to AS i line 1 of a double master.
2 If required, enter the name and a comment for the AS-i line on the "General" tab.
The name for line 1 is identical to the device name of the IE-AS-i LINK (can be set by double-clicking the
IE-AS-i LINK PN IO icon on the IO system; see description above).
3 Set the diagnostics address of the line proxy on the "Addresses" tab page.
This diagnostics address is used to indicate an incoming/outgoing line-specific diagnostic alarm (e.g. AS-i
power failure, ground fault, redundant slave) via the OB82 diagnostics block. The system function block SFB54
"RALRM" can be used to call up additional diagnostic information. This procedure is described in the
IE/AS-i LINK PN IO Manual under section 9.2.2 "Diagnostic alarms".
4 On the "Parameters" tab page, set the IE-AS-i LINK PN IO as an AS-i master.
In particular, the diagnostic alarms must be enabled so that the OB82 can be called up if an error occurs.
When you choose the "Automatic address programming" option (default), an AS-i slave that has failed can be
replaced by a new, identical slave with the address "0" (as-delivered condition) and the IE-AS-i LINK PN IO
automatically assigns the address of the slave that has failed to the new slave.
If this option is deactivated, you have to assign the address manually to the new slave when the slave is
replaced.
5 When a double master is used, double-click the line "[2]" in the AS-i address table and repeat steps 1 to 4 for
AS-i line 2.

11.11.6 Configuring AS-i slaves
Configure the AS-i slaves within the address table.
Note
Reading the actual configuration to the AS-i address table
If an online connection has been established, you can read an existing AS-i configuration to
the AS-i address table.
1. Skip the integration procedure until you reach Completing configuration (Page 576).
2. Follow the integration procedure until Addressing AS-i slaves (Page 577).
3. Then copy the current configuration for each connected AS-i line with the command
"Download to PG".
"AS-i Slave Optionss" tab in the "Properties - IE/AS-i ..." dialog.
4. Parameterize the AS-i slaves subsequently in STEP 7.
Step Action
1 Click the icon for IE/AS-i LINK PN IO on the IO system.
A detailed view of IE-AS i LINK PN IO is displayed in the lower part of the station window.
An AS-i slave can be configured for each AS-i address (1A, B, 2A, B, and so on).
When you use IE/AS-i LINK PN IO as a double master, the following detailed view is displayed: The number of
the AS-i line ("[1]:..." or "[2]:...") is also displayed in square parentheses next to each AS-i address:
All the AS-i address lines contain dummy modules (AS-i proxy slave) as standard.

Step Action
2 You have the following options for changing the AS-i address line assignments:
Drag and drop an AS-i slave from the hardware catalog
Path: PROFINET IO → Gateway → IE/AS i Link PN IO → 6GK1411 2AB10 → V2.0
Select an AS-i slave via the context menu "Insert Object..."
Path: PROFINET IO → 6GK1411 2AB10 → V2.0 → AS i Slave
Copy and insert via the clipboard.
Move the line content by pressing down the left mouse button.
This changes the AS-i address of a configured slave.
3 Note the following rules for assigning addresses:
The lines containing potential target addresses are highlighted in green.
Standard slaves and certain analog slaves use a full AS-i address (A and B address line).
Some AS-i slaves (e.g. CTT5) require the following full addresses, depending on whether the slaves are of
type 2, 3, or 4. Make sure that the following addresses remain free.

AS-Interface system
572 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Step Action
4 Selecting Dummy Modules
A dummy module has the profile ID IO.ID.ID2 = F.F.F / ID1 = F and only exists as a virtual module in HW
Config.
A physical AS-i module, however, always has a profile ID with IO <> F.
The dummy module acts as a proxy for any physical AS-i module and, within the CPU, provides a digital
input/output range (1 input byte / 1 output byte) for this module.
In this case, the configuration (profile ID) of the physical AS-i module is set via the IE/AS-i LINK display or via
Web Based Management (WBM). An actual configuration can also be used as a target configuration.
Alternatively, the configuration can be downloaded to the IE/AS-i Link via the data block interface using the
PLC program (e.g. by calling "Configure complete configuration" (RecordDataWrite index 86). This means that
an AS-i configuration can be changed while the PLC is in operation ("variable AS-i" for systems with more than
one configuration option).
When a dummy module is used, the configuration that was last saved to the EEPROM of the IE/AS-i Link
(regardless of which method was used) is always retained for the physical AS-i module. This is also the case
for the parameter settings of the physical module.
If no physical AS-i module is configured, the digital input byte only returns zero values; the values in the digital
output byte are ignored. If an analog module is configured as a physical AS-i module, the analog data can be
exchanged between the PLC program and the analog module via the data block interface (see call "Write AS-i
slave analog output data"" (RecordDataWrite index 82) or "Read AS-i slave analog input data""
(RecordDataRead index 83)). The same applies to CTTx module data (combined transaction types CTT 1-5 to
AS-i Specification V3.0).
If a dummy module in HW-Config is replaced by a different AS-i slave, the configuration (profile ID) of the
physical AS-i module must be identical to the configuration of the set AS-i slave module so that data can be
exchanged.
A blank line in the AS-i address table indicates that a slave is not used in the AS-i address in question. If a
physical slave is entered in the EEPROM of the IE/AS-i LINK by calling "Configure complete configuration" (in
the AS-i address in the blank line), for example, data still cannot be exchanged because no input/output
address space has been defined for this slave.
5 Diagnostics in the event of an AS-i module failure:
When a physical AS-i module fails/is recovered, a disconnect/connect alarm (OB83) is triggered.
The module that triggered the alarm can be identified by evaluating the local data of the OB83:
Variable OB83_MDL_ADDR indicates the I/O address of the module. The AS-i address can be determined
from this using the system function SFC 49 "LGC_GADR".
Variable OB83_EV_CLASS indicates whether the module has failed/been disconnected (B#16#39) or has been
recovered/connected (B#16#38).
Variable OB83_FLT_ID also indicates whether the module is correct (actual configuration/profile ID matches
the target configuration).

11.12.4 Parameterizing the IE/AS-i LINK PN IO as an IO device
Parameterize IE/AS-i LINK PN IO as an IO device in HW Config of the IO controller.
Step Action
1 Double-click the icon for IE/AS-i LINK PN IO on the IO system. A window is displayed containing the
"Properties - V1.0" dialog, which contains the "General" and "IO Cycle" tabs.
On the "General" tab, set the properties of IE/AS-i LINK PN IO as a node on the IO system.
2.1 Enter a device name of use the system proposal.
When delivered, an IO device does not have a device name. An IO controller cannot address an IO
device until it has been assigned a device name. The IP address is assigned permanently to the device
name. Unlike the complex IP addresses, device names are much more user friendly. The process of
assigning a name for an individual IO device is similar to that for setting the PROFIBUS address for a
PROFIBUS DP slave.
2.2 If you are not using the latest GSD file for the configuration (e.g. you are using one for a predecessor
version), change the version.
You can select the appropriate version in STEP 7 data management by means of a dialog.
2.3 Choose a device number from the drop-down list or accept the system proposal.
In addition to the device name, STEP 7 assigns a device number when an IO device is connected.
This device number is used to identify an IO device in the user program.
Unlike the device number, the device name is nor visible in the user program.
2.4 For an isolated Ethernet subnet, use the IP address and subnet mask proposed by STEP 7.
If the subnet is part an existing Ethernet company network, ask your network administrator for this data.
Open the "Properties - Ethernet Interface IE ASi Link" dialog by choosing "Ethernet...".
2
2.5 If you want to prevent the IO controller from overwriting the IP address in IE/AS-i LINK PN IO,
deactivate the corresponding option. You must set the IP address on the device or assign it via a DHCP
server, for example.
Otherwise, the IO controller downloads the IP address from the configuration to the IO device when it is
started.

582 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Step Action
3 In the "IO Cycle" tab, choose the updating time for an individual IO device.
During the updating time, a PROFINET IO device exchanges its user data with the associated IO controller.
STEP 7 automatically calculates updating times from the existing hardware configuration and the resulting
cyclic data. The updating time applies to either an entire bus segment of an IO controller or just to one IO
device. The shortest possible updating time in a PROFINET system depends on the following factors:
No. of PROFINET IO devices
Volume of configured user data
PROFINET IO communication share (compared with the PROFINET CBA communication share)
Additional cyclic PROFINET services
Properties (performance) of the IO controller
If you increase the updating times of individual IO device that supply user data (non-time-critical), shorter
updating times can be set for other IO devices.
If you change the hardware configuration (e.g. add new IO devices), the updating time may change. A change
message appears the next time you open the dialog.
4 Configure the response monitoring time.
The response monitoring time cannot be set directly but instead as a "No. of accepted updating times with
missing IO data". Multiplying the updating time results in the response monitoring time.
If the IO controller does not supply the IO device with I/O data within the response monitoring time, the IO
device switches to safe mode.
Only change the default setting in an emergency (e.g. during the commissioning phase).
Parameterize the diagnosis address in the "Properties - IE-ASi-Link" dialog for slot "0". 5
5.1 In the AS-i address table, double-click the first line with the "IE-ASi-Link" module.
A window is displayed containing the "Properties - IE-ASi-LINK" dialog, which contains the "General",
"Addresses", and "Parameters" tab.

Step Action
5.2 On the "Addresses" tab page, enter the diagnostics address or use the system proposal.
If you enter an invalid address, the system proposes a new one.
The IO controller uses the diagnostics address to find out about the failure or return of an IO device and
starts the OB 86. You can also read the diagnosis of the IO device under this address with SFB 52 and
include it in your user program.
11.12.5 Parameterizing AS-Interface
Parameterize the properties and behavior of IE/AS-i LINK PN IO as an AS-i master in the
"Parameters" tab.
Step Action
1 Call up the "Parameter" tab in the "Properties - IE-AS-i-LINK" dialog.
2 In the relevant option box, activate the alarm enable for diagnostic interrupts.
These alarms trigger channel diagnoses (PROFINET IO format ID 8000H).
Line-specific diagnostic interrupts (e.g. AS-i Power Fail) are signaled via the logical I/O address or
diagnosis address of the line proxy module (slot "0" or "100").
Slave-specific diagnostic interrupts (e.g. slave I/O fault) are signaled via the logical I/O address or diagnosis
address of the relevant slot (slot 1 ... 63, 101 ... 163).

3 When the "Address programming" option is active, an AS-i slave that has failed can be replaced by a new,
identical slave (same IO, ID, ID1, and ID2 code) with the address "0" (on delivery). IE/AS-i LINK PN IO
automatically assigns the new slave the address of the old one.
11.12.6 Configuring AS-i slaves
Configure the AS-i slaves via the slot assignment in the station window.
The individual configuration of the AS-i slaves has the following benefit:
the IO controller transfers the default settings from the configuration to IE/AS-i LINK PN IO
every time the device is started.
Step Action
1 If you require a different memory capacity for an AS-i address, delete the default I/O module.
If there are certain AS-i addresses that you do not use, delete the I/O modules (optional).

Move the line content by pressing down the left mouse button.
The modules that can be selected differ with respect to their memory capacity requirements.
"0 Byte": an additional dummy module for AS-i slaves that require more than one AS-i address.
"1 byte" for AS-i slaves that require up to 1 byte of address space.
"1 word" for AS-i slaves that require up to 2 bytes of address space.
"2 words"/"4 words" for AS-i slaves that require more than 2 bytes of address space.
"DI" / "AI" for AS-i slaves that require an input address space.
"DO" / "AO" for AS-i slaves that require an output address space.
Example:
the analog module "2 words AI", for example, is suitable for a two-channel analog input slave.

If you change the default setting "FH" of a code, the IO controller overwrites the configuration data stored
in IE/AS-i LINK PN IO when it starts. Otherwise, the values stored in IE/AS-i LINK PN IO are valid for
the configuration. Subsequent setting of the parameter bits is, therefore, irrelevant.
4.8 Choose the parameter bits of the AS-i slaves from the drop-down lists.
For explanations of the parameter bits, consult the manufacturer documentation for the AS-i slaves.

System diagnosis 12
12.1 Overview of diagnostic options
System diagnosis
System diagnosis can only be carried out when AS-Interface is integrated in an automation
system with a joint database. The main benefit of system diagnoses is that you gain a
comprehensive and standardized diagnostic view of the system components:
Automatic signaling of system errors
Automatic hardware diagnosis
Diagnosis of all the system components from any point in the plant
Localization of the error source
Preparation of the process diagnosis even while the user program is still being created
Use of the integrated diagnostic functions for the user program (e.g. for programming
plain-text messages or for transfer to HMI (Human Machine Interface))
Diagnostics data can be exchanged in the following ways:
Displaying messages in the engineering tool interface
Reading diagnostic telegrams from cyclic data exchange (e.g. DP slave diagnosis,
system status lists)
Reading diagnostic data blocks via acyclic commands
Integrating diagnostic blocks in the user program
Device-related diagnosis
Device-related diagnosis involves local diagnosis or independent remote diagnosis
(Web-based management). AS-Interface does not need to be integrated in an automation
system for this purpose.
Device-related diagnosis offers the following options:
Display LEDs on CP and gateways
Status display
AS-i voltage
Bus fault
System error
Configuration error

12.2 Diagnostics with SIMATIC
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 593
12.2 Diagnostics with SIMATIC
If the diagnostics-capable AS-i master identifies external or internal errors during operation, it
triggers a diagnostic interrupt (DAL) on the S7 I/O bus.
Note
Diagnostic interrupt enable
Diagnostic interrupts must be enabled (e.g. on the "Operating Parameters" tab in the STEP 7
dialog of the AS-i master).
If the PROFIBUS DP master or IO controller does not support diagnostic interrupts, it sends
a status message as a device-related diagnosis instead.
In the user program, you can tell that the diagnostic interrupt has been deactivated in OB 82
by the module address in question:
OB82_MDL_ADDR = I/O address of AS-i binary module -> Diagnostic interrupt present.
OB82_MDL_ADDR = diagnostic address of the AS-i master -> Diagnostic interrupt is not
available; a status message signals the alarm event.
Note
No AS-i diagnostic message with insufficient power supply
If the power supply for the AS-i master falls below 14 V, no diagnostic messages can be
output. The PROFIBUS DP master or IO controller, however, informs the user program that
the AS-i master has failed.
External alarm events
Configuration errors in protected mode (e.g. missing, incorrect, or unconfigured
AS-i slaves)
AS-i power fail in protected mode
In configuration mode, diagnostic alarms are not output for external alarm events.
Internal alarm events
EEPROM errors
The S7-CPU determines the alarm source and reads data block 0 from the AS-i master. It
then interrupts the cyclic user program, enters the diagnostic event in the system status list
and diagnostic buffer, and then behaves as follows:
If organizational block OB 82 is not programmed, the CPU switches to the STOP status.
Otherwise, the CPU operating system starts OB 82.
The local data area of OB 82 (bytes 8 to 11) contains the logical basic address and 4-byte
diagnostics data from data block 0 of the defective module. Additional diagnostics data from
other data blocks can be called up via the user program.
Once OB 82 has ended, the CPU acknowledges the diagnostic interrupt in the AS-i master
and resumes the cyclic program (OB 1) at the point where it was interrupted.
System diagnosis
12.2 Diagnostics with SIMATIC
AS-Interface system
594 System Manual, 11/2008, 3RK2703-3BB02-1AA1
Incoming and outgoing alarm events
If an external alarm event results in a fault-free status being set, this is followed by an
outgoing diagnostic interrupt. In OB 82, bit "OB82_MDL_DEFECT" = 0.
All other alarm events result in an incoming diagnostic interrupt. In OB 82, bit
"OB82_MDL_DEFECT" = 1. Internal alarm events are always incoming.
Alarm behavior depending on the system status
Alarm events do not trigger diagnostic interrupts in the following system statuses:
STOP status of the CPU:
When the CPU switches to the STOP status, this causes the external and internal alarm
events to be deleted. Bit "OB82_MDL_DEFECT" and the error bits in DB 0 are reset.
AS-i master in configuration mode:
When the AS-i master switches from protected mode to configuration mode, this causes
the external alarm events to be deleted.
Previous, unacknowledged diagnostic interrupts
The error messages remain in the diagnostic buffer, however.
When the diagnostic interrupts can be triggered again, a comparison of the current overall
configuration in the AS-i master (AS-i slave configuration and internal, alarm-relevant status)
and the configuration signaled beforehand by means of a diagnostic interrupt causes the
AS-i master to behave as follows:
Not equal to: the AS-i master triggers a diagnostic interrupt with the current configuration
data.
Equal to: the AS-i master does not trigger a new diagnostic interrupt.

12.3.3 System status lists
The CPU for the SIMATIC modules saves the current status of the automation system
cyclically in the "system status list". The data in the system status list can only be read and
not changed. It is a virtual list that is only compiled on request. In addition to the menu
options in STEP 7, you can read sub-lists of the system status list by means of SFC51
"RDSYSST". Sub-lists for diagnosing PROFINET IO or PROFIBUS DP systems can be
called up when you specify the sub-list number. The following sub-lists can be used for
processing AS-i error messages further:
System data:
system data is fixed or parameterized characteristic data for a CPU.
Alarm error assignment: assignment of alarms/errors to OBs
Alarm status: current status of alarm processing/generation
Status of priority classes: Which OB is being processed? Which priority class has
been blocked by means of parameterization?
Operating status and operating status switchover: possible operating statuses, last
switchover, current operating status
Diagnostic status data in the CPU:
this describes the current status of the components monitored by system diagnosis.
Diagnosis nodes: diagnostics-capable modules registered on the CPU
Start event list: start events and priority classes of the OBs
Module status data: status data for all the plugged-in, defective,
process-alarm-generating, assigned modules
Diagnostics data on modules:
apart from the CPU, other diagnostics-capable modules (SMs, CPs, FMs) exist whose
diagnostics data is entered in the system status list.
Module diagnosis info: module start address, internal/external errors, channel errors,
parameter errors (4 bytes)
Module diagnostics data: all the diagnostics data of a particular module
Entries in the diagnostic buffer:
the maximum number of entries depends on the S7-CPU.
S7-300-CPUs return max. 10 data blocks
S7-400-CPUs return max. 21 data blocks
Step Action
1 You can read sub-lists of the system status list with SFC51 "RDSYSST".
For parameterization, refer to the STEP 7 documentation.
2 Store the diagnostics data in a data block in the user program.
3 Use SFC52 "WR_USMSG" to forward diagnostics data to other registered system nodes.

The AS-i masters provide diagnostic data blocks on request. The structures of the diagnostic
data blocks are described in the following device-specific sections.
Step Action
1 Read the data blocks of the AS-i master.
The following STEP 7 program blocks are available:
SFC59 "RD_REC" (not for IO devices)
This system function has been replaced by SFB52.
SFB52 "RDREC"
SFB54 "RALRM"
SFB54 "RALRM" receives an alarm with the associated data from the AS-i master and makes this available
with its output parameters. The data in the output parameters contains both the start data for the OB called
up and data from the alarm source.
Call up SFB 54 within OB82.
To parameterize the program blocks, refer to the STEP 7 documentation.
2 Store the diagnostics data in a data block in the user program.
12.3.5 Diagnostics blocks for the user program
Software blocks, which you can use to access AS-Interface diagnostics data, are available
for STEP 7. In a user program, the data can be evaluated, archived, and/or output for
displaying errors on an operator panel (e.g. WinCC flexible / ProTool).
FC107 "FC_HMICE_ASI" for standard AS-i diagnosis
The function FC107 "FC_HMICE_ASI" reads diagnostics data from the AS-i master and
returns status data that is forwarded to other program sections. The diagnosis can take place
across several AS-i bus systems. The function can also be used for standard AS/i networks
independently of a safety monitor.
Step Action
1 Enter each configured AS-i Master in the "SO_51_ASIIndex" text list.
2 Call up the function FC107 in the cyclic OB1 for each AS-i master once.
3 For the diagnosis, call up the function FC107 directly in OB82.

Command interface
Further diagnostics data can be accessed via the command interface. To do so, use the call
Read_data_block (SFC59 or dpc*_read) to authorize the AS-i commands. Suitable
AS-i commands include "Read_extended_lists_and_flags" (0030H) or
"AS-i_status/diag_of_F_slaves" (0051H).
When SIMATIC S7 is used as a PROFIBUS DP master, a special function (FC ASI_3422) is
available for using the AS-i commands. This function processes the report for
AS-i commands independently.
12.8 Special features of diagnosis via IE/AS-i LINK PN IO
PROFINET IO uses a manufacturer-independent data block structure with diagnostics data.
Diagnostic interrupts trigger channel diagnoses (PROFINET IO format ID 8000H) for
defective channels only. STEP 7 allows channel diagnoses for all sub-modules of
PROFINET IO devices to be read.
AS-i slave-specific diagnostic interrupts (e.g. I/O errors) are assigned to the logical I/O
address or diagnosis address of the relevant slot (1 ... 63, 101 ... 163).
Line-specific diagnostic interrupts (e.g. AS-i Power Fail) are assigned to the logical I/O
address or diagnosis address of the line proxy module (slot 0 or 100).
Evaluating the diagnostics data with SFB54
With SIMATIC S7, detailed diagnostics data can be accessed with SFB54 "RALRM" via the
block parameter "AINFO". The alarm structure is provided in the documentation or help for
SFB54. The specific meanings of the fault types (AINFO, bytes 32 ... 33) for
IE/AS-i LINK PN IO are described in the following table.

"Read_lists_and_flags" (0054H) or "Read_AS-i_line_error_counter" (0060H).
When an IO-Base programming interface is used, the block "pnio_rec_read_rec()"
corresponds to SFB52 .

13.1 Checklist for beginners
This checklist aims to make it easier for you to use AS-Interface.
1. How many inputs and outputs are required?
The number of inputs and outputs determines how many AS-Interface networks are required.
2. How much power do the I/Os require?
The total power requirements of the required modules determine which AS-Interface power
supply unit is selected. Since power supply units cannot be connected in parallel, a power
supply unit dimensioned in line with the power requirements must be used.
3. Are any special cables required?
Both flat and round cables can be used. External influences determine whether rubber, TPE,
or PUR cables are required. Repeaters or extenders must always be used when cable
lengths exceed 100 m.
4. Have the addresses been correctly assigned?
For reasons of clarity, an overview must be created that clearly shows which addresses are
assigned to which slaves. Duplicate addresses, for example, may not be recognized as
errors by the master.
5. Which modules belong to which addresses?
The modules and slaves that have been addressed must be carefully labeled.
6. When are the modules installed?
The modules must not be installed until the activities described in rules 4 and 5 have been
completed. The cable itself can be routed at any time, however.
Planning and configuration
13.2 Configuration
AS-Interface system
618 System Manual, 11/2008, 3RK2703-3BB02-1AA1
7. How is the entire system configured?
The configuration is simply read by entering the AS-Interface profile for each slave in the
master. This normally occurs automatically, but can also take place via the controller
software.
8. Are the slaves detected?
You first have to check whether the master has detected all of its slaves. Only then can the
system be set to protected mode and the controller switched to RUN.
9. How is the system tested?
As with the PLC, input/output tests are carried out, that is, the sensors are actuated locally
and checked in the PLC.
10. How is the entire system launched?
You can either create the controller software as usual, or use existing software. If you use
existing software, the symbolic assignment of the addresses may have to be adjusted.
13.2 Configuration
With AS-Interface, configuration simply means that a list of configured slaves is created and
then stored in the master. Configuration is normally carried via the master,
that is, the master reads the network configuration automatically. (Requirements for special
applications can also be created in the PLC.)
During configuration, the slave address and slave type (ID code), the I/O configuration
(I/O code), and the parameters (for intelligent sensors), are defined (if available). The master
uses the list to check whether the actual configuration matches the target configuration. The
master can only carry this out, however, provided that the slaves have already been
addressed.

13.3 Addressing the I/O modules
AS-Interface system
System Manual, 11/2008, 3RK2703-3BB02-1AA1 619
13.3 Addressing the I/O modules
Unique addressing
In the factory setting, each I/O module (slave) has the address 0. It is detected by the master
as a new slave that has not yet been addressed and, in this condition, has not yet been
integrated in standard communication/data exchange.
To enable data to be exchanged between the master and slaves, you have to assign a
unique address for all the slaves before creating the interface network.
You can choose the address of the slave as required:
In address space 1 to 31
In extended addressing mode (as of AS-i version 2.0/2.1) in the address space 1A to 31A
and 1B to 31B.
Addressing the slave
You can address a slave in different ways:
Offline using an addressing unit (Page 40)
Online via the AS-Interface system master
13.4 Parameterization
You do not normally have to parameterize slaves.
Only intelligent slaves for which the relevant option is also available are parameterized. The
datasheet for the corresponding slave specifies whether or not it needs to be parameterized
and the functions of the parameters.
While the address of a slave never changes during normal operation, parameters are subject
to change. For this reason, a distinction is made between variable and fixed parameters.
Fixed parameters are defined once (during configuration).
An example of this is an analog input module that is set via a parameter to a current range of
0 to 20 mA or 4 to 20 mA. The parameters themselves are bits of which four are available for
each module and which are each set to either 0 or 1. They are transferred from the master to
the slaves when the system is started.
Planning and configuration
13.5 Operation
AS-Interface system
620 System Manual, 11/2008, 3RK2703-3BB02-1AA1
13.5 Operation
The AS-Interface system has been set up
The AS-Interface system can be commissioned as soon as it has been fully set up:
All the components have been installed
The slaves have been addressed and (if necessary) parameterized
Configuration is complete
Commissioning can now begin
AS-Interface system in normal operation
The system switches to normal operation and the master runs in protected mode. Only the
slaves that have been configured are activated. Slaves that have not been configured (e.g.
new ones) simply cause an error message to be output. You must include these in the list of
configured slaves.
The system is continuously monitored both when it is restarted and during normal operation.
The higher-level controller receives the data required for this (e.g. voltage, mode, incorrect
configuration, etc.) from the AS-Interface master (e.g. in the form of a diagnosis).
Configuring new slaves
To include slaves that have not been configured in the communication network, they need to
be configured:
1. Switch to configuration mode.
2. Use the "Configure slaves" to include new slaves in the communication network.

1.1 AS-i Power24V and data decoupling units
1.1.1 Overview
AS-i Power24V is an enhancement of the AS-Interface specification. This enhancement
specifies that an AS-Interface network can alternatively also be supplied with the nominal
voltage of 24 V DC instead of the nominal voltage of 30 V DC that is typical for AS-i power
supply units. This makes it possible to use a standard 24 V power supply unit for supplying
an AS-Interface network.
AS-i Power24V is not a new bus system. The data communication remains the same so that
all AS-i components work the same at operating voltages of 30 V and 24 V if they are
approved for the respective voltage.
The basic change in AS-i Power24V relates to the power supply unit:
Primary voltage
e.g. 120 / 230 V AC
AS-i
cable
PELV / SELV
PE
ASI +
FE / GND
ASI −
In addition to DC power generation, an AS-i power supply unit contains a data decoupling
circuit, which is absolutely necessary for data communication.
As is evident from the picture, all of the operating current of the AS-Interface power supply
flows through the data decoupling unit, which needs to be sized for the required current.
In an AS-i power supply unit with integrated data decoupling, the nominal currents of the DC
power generation and data decoupling need to be harmonized.

If an AS-i power supply unit is replaced with a standard power supply, the data decoupling
needs to be looped into the AS-i cable as a separate device:

The possibility of using an existing 24 V power supply unit reduces costs and enables AS-
Interface to be employed also for small applications. As a result, the advantages of AS-
Interface are also of benefit for these applications.
The AS-i data quality is equally high in both operating modes. Up to 31 standard slaves or 62
A/B slaves can be connected to each, including safe slaves.
As is the case with all voltage supplies, it must be ensured that the voltage at the location of
the load is high enough, i.e. the voltage drop on the AS-I cable needs to be considered.
Therefore, in AS-i Power24V, the AS-i cable length is limited to 50 m.
The AS-i master, the AS-i slaves and the sensors or actuators must be suitable for low
voltage.

1.1.2 The AS-Interface cable for AS-i Power24V
Shaped cable
For AS-i Power24V, the same yellow AS-i shaped cable is used as in standard AS-i.
The shaped cable transmits data and power.
As with standard AS-i, the data are transported over the cable as an alternating-current
component (alternating pulse modulation with 167 kHz sin² pulses), the power as a direct-
current component.
The user does not need to perform any settings for this functionality.
Number of nodes
Up to 62 slaves, one master, and up to four additional passive nodes (without their own
AS-i address) can be connected to a network.
Cable length
The total length of the AS-i cable is limited to 50 m for AS-i Power24V.
This limitation was set in order to limit the voltage drop on the cable so that even at the
lower feed voltage a sufficiently high DC voltage level is applied to slaves and sensors.
Transmission quality
The quality of the data signal is equally high in AS-i Power24V and standard AS-i.
The amplitude of the alternating-current component on the cable and the transmission
procedure are identical in the two versions.
Other cables
If a round cable is used instead of the AS-i shaped cable, then in AS-i Power24V a
correction factor is normally not needed for the cable length.
The data signal (i.e. the alternating-current component) is normally high enough with a
maximum cable length of 50 m.
However, when the core cross-section is small, a greater voltage drop involving the direct
current component must be taken into account.
Expansion options
Repeater and extension plug cannot be used with AS-i Power24V.
For the enlargement of the network span, an AS-i Power24V network structure can in
principle be updated to a standard AS-i network (with nominal voltage 30 V DC) by
replacing the power supply unit.

Because the slaves are normally arranged in a spatially distributed manner along the AS-i
cable, the current at the beginning of the cable (infeed) is higher than at the end of the cable
(at the most distant slave). The actual voltage drop is therefore less than the value that is
determined in a single calculation with total current and total cable length using the
aforementioned formula.
If the slaves are evenly distributed over the linear cable and the current drain of any slave is
equally high, the following formula can be used for the voltage drop

1.1.3.3 Voltage reduction in the slave module
The AS-i module provides the supply voltage for the connected sensors. This supply voltage
is drawn from the AS-i cable. For circuitry design reasons, the voltage is reduced here by
approximately 4 V.
The voltage difference

1.1.3.6 Calculation examples
Example 1:
10 AS-i slaves (K45 modules type A/B slave) are installed equally distributed over the 50 m
cable. 150 mA are needed for each slave (including approx. 100 mA sensor supply). The
24 V power supply unit is located at the beginning of the cable.
Approximate calculation:
Total current from the power supply unit at the beginning of the cable: 1.5 A (plus power
consumption of the AS-i master, with CP343-2 max. 100 mA)
Total voltage drop at the end of the AS-i cable: approximately 0.5 V +
1.0 V = 1.5 V
Voltage across the last slave: 24.0 V – 1.5 V = 22.5 V
Voltage across the last sensor: 22.5 V – 5.4 V = 17.1 V

Example 2:
20 slaves (K45 modules type A/B slave) are installed equally distributed over the 50 m cable.
150 mA are needed for each slave (including approx. 100 mA sensor supply). The 24 V
power supply unit is located at the beginning of the cable.
Approximate calculation:
Total current from the power supply unit at the beginning of the cable: 3.0 A (plus power
consumption of the AS-i master, with CP343-2 max. 100 mA)
Voltage drop at the end of the cable: approximately 0.5 V + 2.0
V = 2.5 V
Voltage across the last slave: 24.0 V – 2.5 V = 21.5 V
Voltage across the last sensor: 21.5 V – 5.4 V = 16.1 V
Example 3:
30 slaves (K45 modules type A/B slave) are installed equally distributed over the 50 m cable.
120 mA are needed for each slave (including approx. 70 mA sensor supply). The 24 V power
supply unit is located at the beginning of the cable.
Approximate calculation:
Total current from the power supply unit at the beginning of the cable: 3.6 A (plus power
consumption of the AS-i master, with CP343-2 max. 100 mA)
Voltage drop at the end of the cable: approximately 0.5 V + 2.3
V = 2.8 V
Voltage across the last slave: 24.0 V – 2.8 V = 21.2 V
Voltage across the last sensor: 21.2 V – 4.6 V = 16.6 V
1.1.3.7 Practical tips
The sensors must be selected in such a way that the real sensor voltage is within the
acceptable range of the sensor operating voltage. In practice, sensors with the standard
voltage range of 10 to 30 V can be used.
With many power supplies, the output voltage can be set slightly higher than the nominal
voltage of 24 V DC, so that the voltage drop on the cable can be compensated. This
setting option can also be used for AS-i Power24V.
All AS-i Power24V components function within the overall voltage range between the
nominal voltages of 24 V and 30 V. (Any exceptions are explained in the operating
instructions.)
The AS-i voltage on the Power24V-capable slave must be at least 18 V.

1.1.4 Masters and links for AS-i Power24V
The current list of masters and links that are suitable for AS-i Power24V are available in the
Internet (http://support.automation.siemens.com/WW/view/en/42806066).
The following properties are important for the AS-i masters and links:
If the voltage on the AS-Interface is less than 22.5 V (+/-1 V)
and voltage monitoring is active (delivery condition), the master generates the message
"AS-i POWER FAIL" (APF) and
stops the operation of the AS-Interface network
The slaves on the AS-Interface network switch off automatically if there is an undervoltage.
In order to ensure flawless operation of the AS-i master in an AS-i Power24V network, the
voltage monitoring of the master must be deactivated.
In the delivery condition, the voltage monitoring is activated and the master is thereby preset
for operation at a 30 V supply voltage.

1.2 AS-i data decoupling units
1.2.1 Function overview
Using the data decoupling units
In order to supply AS-Interface from a standard power supply unit, a data decoupling unit
must be connected between the voltage supply and AS-i network.
The data decoupling generates the specific signal shape of the AS-i data signals and
prevents the AC voltage pulses of the data signals from being short-circuited by the DC
voltage supply.
A DC voltage supply can feed several data decoupling units so that multiple AS-i networks
can be operated on a single DC voltage supply.
A single data decoupling unit contains a data decoupling circuit for operating one AS-i
network.

Figure 1-3 AS-i Power24V double network
As many data decoupling units as desired can be connected in parallel to a DC voltage
supply in order to operate a corresponding number of AS-i networks.
The input side of the data decoupling unit is typically connected to a standard power supply
with a nominal voltage of 24 V or 30 V.
Operation of the AS-Interface network on a 24 V DC voltage supply falls within the AS-i
Power24V category. Because a standard 24 V power supply unit does not include a data
decoupling circuit, with Power24V an additional data decoupling unit is absolutely necessary.
The DC voltage supply can simultaneously supply the 24 V control voltage for the system
controller (PLC) or the entire system. Obviously, the DC voltage supply must be large
enough to supply all connected AS-i networks and other loads with power.
For an AS-i network with unlimited AS-i properties, a 30 V DC voltage supply must be used.
This is especially necessary if the voltage level of the sensor supply is insufficient due to a
voltage drop on a (longer) AS-i cable, or slaves and other AS-i components are used that are
not suitable for AS-i Power24V. An AS-i power supply unit supplies a voltage of 30 V and
simultaneously includes integrated data decoupling. A standard 30 V power supply requires
an additional data decoupling.
If the data decoupling unit is connected to an AS-i power supply (i.e. 30 V DC voltage supply
with integrated data decoupling), the data decoupling circuit integrated in the AS-i power
supply becomes inactive. It is not technically possible to produce a second AS-i network by
connecting a single data decoupling unit to an existing AS-i network. If a double data
decoupling unit is connected to an AS-i power supply unit, two AS-i networks can be
operated separately from each other on the two outputs of the double data decoupling unit.

Requirements of the DC voltage supply
The DC voltage supply needs to produce an extra low voltage according to PELV Standard
(Protective Extra Low Voltage) or SELV Standard (Safety Extra Low Voltage).
The nominal voltage must be within the 24 … 30 V DC range.
For trouble-free communication in the AS-i network, it is necessary for the DC voltage supply
to have a low residual ripple:
Residual ripple Vppnoise < 250 mV
Modern switched mode power supplies can easily satisfy this requirement; check the
residual ripple in the power supply data sheet.
Industrial power supplies from the Siemens SITOP product range are recommended.
Note
If high spurious peaks due to switching operations on the control voltage are expected, a
separate power supply unit should be provided to supply the AS-i networks.
Grounded and ungrounded DC voltage
The relevant standard (EN 60204 part 1, DIN VDE 0113) prescribes a grounding or
corresponding measures for control voltages (e.g. ground fault detection) to prevent
dangerous movements etc. when a ground fault occurs.
Therefore, the 24 V control voltage is normally grounded, i.e., the negative pole of the DC
voltage supply is connected to the system ground.
Although an AS-i network cannot have any connection to the system ground, a grounded DC
voltage can be used for AS-i Power24V. This can be explained as follows:
The data decoupling separates the DC voltage from the communication signal. For fault-
tolerant communication, the communication signal is transmitted symmetrically, i.e. the AC
voltage signal is transmitted both to the positive pole and as a reversed-polarity signal to the
negative lead. Any noise is injected equally on both conductor wires. By calculating the
difference in the two transmitted signals, the desired communication signal is recaptured
while the interference signals cancel each other out.
The "FE" terminal represents the reference potential for both transmitted AC voltage signals
and must be connected to the system's ground in order to obtain an optimal symmetry of the
AC voltage signals. An additional grounding of the supplying DC voltage, does not effect the
symmetry - provided that this grounding occurs on the supply side of the data decoupling
unit (terminals L+ / M). A grounding on the side of the AS-i network (terminals ASI1+ / ASI1-
and ASI2+ / ASI2-) subtly disturbs the symmetry and must not be carried out.

Reverse polarity and undervoltage protection
If supply voltage (L+ / M) is connected with reversed polarity or if the supply voltage is too
low (below 21 V), both outputs ASI1 and ASI2 are switched off (only with the double data
decoupling unit). A supply voltage connected with reversed polarity is not transmitted to the
outputs.
If the input voltage is correct, the outputs are automatically switched on.
The two outputs of the double data decoupling unit switch on with a 200 ms time differential
in order to reduce the starting current for the supplying power supply.
Overload and short-circuit protection
The data decoupling unit limits the current in the AS-i network and is short-circuit proof.
When there is a short circuit or overload on an AS-i cable, the involved output ASI1 or ASI2
is switched off (electronic transistor output) and is thereby decoupled from the power source
(selectivity). In the double data decoupling unit, a short circuit on one AS-i network has no
effect on the other AS-i network, if the supplying power supply unit has sufficient capacity
reserves.
The restart occurs automatically after about 5 seconds.
The absence of the AS-i voltage can be detected and signaled by the connected AS-i
master.
The signaling contacts are not affected by a short circuit/overload.
The overload current value can be set in four stages: 2.5 A – 3.0 A – 3.5 A – 4.0 A. (with a
tolerance of approx. +0.1 A). The maximum value on delivery is preset at 4.0 A. The
reduction of the overload current value is only required if the supplying power supply does
not yield the required output for the maximum total current of the module.
Example:
Use of a double data decoupling unit on a 24 V power supply with a nominal current of 10 A.
The AS-i networks on ASI1 and ASI2 each require a maximum of 3 A, the remaining
controller a max. of 4 A.
The overload current value is set by the user at 2 x 3 A for ASI1 and ASI2. When there is an
overload on an AS-i cable, the supplying power supply is not overloaded, so the rest of the
system continues to operate.
The shutdown in the event of an overload occurs after a delay of up to 3 s, in order to take
into account starting currents. Starting at 130 % overload, the shutdown comes after just
500 ms; in the event of a short circuit, it comes after approx. 100 ms.
The supplying power supply must have corresponding reserve capacity.

System Manual, 09/2010, A5E03003228020-01 19
Integrated ground fault detection with error log
The AC voltage signal of the data communication is symmetrically aligned with the system
ground, so that interference pulses (e.g. due to switching operations) have an equal effect on
the positive cable and the negative cable and as a result are automatically compensated.
This noise suppression functions in principle only under the following assumptions:
The ground terminal on the data decoupling unit must be connected to the system
ground. This connection produces the required balancing.
The AS-i cable must not be connected at any point to the system ground. Because the
sensor supply is transferred from the AS-i cable, the sensor cable also must not be
connected to the system ground. A capacitive connection (capacitor for the ground) is not
allowed.
If any of these assumptions is not satisfied, the AS-Interface system becomes susceptible to
disturbances. Depending on the impedance of a ground fault, sporadic communication faults
or complete failure can occur on an AS-i cable or a sensor cable.
Note
The functionality described above regarding the system ground also applies analogously for
AS-i networks that are operated with a conventional AS-i power supply (with integrated data
decoupling): The ground terminal (GND) on the AS-i power supply unit must be connected to
the system ground in order to suppress faults.
In order to reliably detect a ground fault, the data decoupling unit has an integrated ground
fault detection. If a ground fault is detected, an internal error log is set and a relay signaling
contact is closed, which is routed to the outside via terminals. The status LED on the module
indicates via a yellow flashing light that the error log is set. A yellow continuous light
indicates that the ground fault is currently still present. Short-term ground faults which occur,
for example, when the cable insulation gets crushed, are also recorded via the error log.
The error log must be reset by the user after the ground fault has been eliminated. After the
reset, the relay contact is opened again. Resetting is not possible when the ground fault is
still present. Resetting can be done by pressing the button (RESET/TEST) on the module or
via potential-free terminal input (Y1, Y2).
The ground fault detection of the data decoupling unit functions both with an ungrounded
voltage and if the DC voltage supply of the data decoupling unit (terminals L+ and M) is
grounded. The detection circuit detects only ground faults on the wiring system that is
connected to the ASI terminals. Because the ground fault detection evaluates the
communication signals, it is absolutely necessary for the function of the ground fault
detection that an AS-i master be connected and turned on.
In order to ensure the availability of the system, a ground fault should be eliminated
immediately.

By appropriate external wiring of the signaling contacts, the supply of the AS-i network can
be interrupted in the event of a ground fault. The provisions of the relevant standard are to
be heeded here; see for instance EN 60204 part 1, DIN VDE 0113:
"Ground faults in any control circuit must not lead to inadvertent start-up or potentially
hazardous movements or prevent the stoppage of the machine."
Note
The ground fault detection module 3RK1408-8KE00-0AA2 or 3RK1408-8KG00-0AA2 that is
still provided can only be used in AS-i networks with ungrounded DC voltage supply. For
AS-i Power24V, this separate ground fault detection module is not necessary because the
data decoupling unit has integrated ground fault detection.
Setting the AS-i address
The AS-i data decoupling unit does not have an AS-i address.

1.2.4 Configuration and operation
Overload current value setting
The set overload current value can only be changed when the supply voltage is turned on.
Carry out the following steps:
Step Action / Reaction
1 Activate setting mode by holding down the button ( approximately 3 …
5 seconds) while the voltage L+ is switching on; the PWR LED rapidly flashes green
(4 Hz)
2 LED ASI1 flashes green one to four times, then once red.
This sequence is continuously repeated. The number of green flashing signals
represents the current value according to the table below.
3 Change the current value by pressing the button ( approximately 0.5 s) briefly:
4.0 A → 3.5 A → 3.0 A → 2.5 A → 4.0 A etc.
4 Save the new current value for ASI1 by pressing and holding down the button (
approximately 3 … 5 s).
In the double data decoupling unit, the LED ASI2 then begins to flash, and you can set the new
current value for ASI2 as described in steps 2 to 4.
Completion Then the program exits setting mode and normal operation is started.
Flashing sequence STATUS ASI1 / ASI2 Imax for ASI1 or ASI2
green/red 4.0 A (delivery condition)
green/red 3.5 A
green/red 3.0 A
green/red 2.5 A
Checking the set overload current value
Checking the set overload current value is possible during operation.
Proceed as follows:
Step Action / Reaction
1 Make sure that there are no ground fault signals (no yellow LED indications; see
Diagnostics below.
Press the button briefly ( approximately 0.5 s) during operation to activate display
mode:
2 Observe the flashing behavior of the LEDs:
LED ASI1 flashes green 1 to 4 times.
The number of green flashing signals represents the current value according to the
table below
In the double data decoupling unit, the LED ASI2 then begins to flash, and you can read the current
value for ASI2 as described under step 2.
Completion Then the program exits display mode.
If necessary, the setting can be checked again; see step 1.

Testing the signaling contacts
The relay contacts C13 / C14 and C13 / C24 (only with double data decoupling unit) can be
switched on manually for testing the external wiring.
To do this press the button in normal operation (after powering up) and keep it pressed for 3
to 5 s . Inside the device, a ground fault is simulated on an AS-i network and the error
log is set. The AS-i network itself is not grounded here. Just like after a real ground fault, the
status LED flashes yellow and the signaling contact is closed.
To reset the error log, the button must be pressed briefly or a remote reset is activated. If a
real ground fault is present, the error log cannot be reset.
In the double data decoupling unit, the button must be pressed a second time and held down
in order to also simulate a ground fault on the second AS-i network. The associated
status LED flashes yellow, and the associated signaling contact is closed. The status of the
other error log or signaling contact is irrelevant here. The signaling contacts in this context
can be switched on individually (by interim reset) or else together.
Remote reset
In addition to the button on the device, the error log can be reset via a pulse on the remote
reset input (terminals Y1 / Y2).
The remote reset pulse must be present as a HIGH signal for at least 100 ms in order to
execute a reset. In order to be able to trigger a new remote reset, a LOW signal must be
present on the remote reset input for at least 100 ms.

The single data decoupling unit has a relay contact (terminals C13 / C14) in order to signal a
ground fault on the AS-i network.
The double data decoupling unit has two relay contacts (terminals C13 / C14 for ASI1 and
C13 / C24 for ASI2) for separate signaling of a ground fault on the respective AS-i network.
The contacts (C13) have a common root.
The signaling contact is closed if a ground fault has been identified.

ASIsafe: Safe AS-i outputs 2
2.1 Safe SlimLine module S45F
The ASIsafe concept enables the integration of safety-oriented components like
EMERGENCY STOP operator panels, protective door switches or safety light arrays in an
AS-Interface network. These are fully compatible with the standard AS-Interface components
(master, slaves, power supply unit, repeater, etc.) in accordance with IEC 62062/EN 50295
and are operated together on the yellow AS-Interface cable. The technology of the safe AS-i
outputs enhances ASIsafe.
In addition to the acquisition and evaluation of safe signals, now a safety-oriented
decentralized shutdown is possible directly via AS-Interface.
A fail-safe controller or special master is not required. The evaluation of the safe signals is
performed in the AS-i safety monitor. The master treats safety slaves like all the other slaves
and receives safety data for information purposes only. This means that all existing AS-
Interface networks can also be enhanced. ASIsafe ensures that a maximum response time
of 40 ms can be achieved. This is the time between the signal being applied to the input of
the safe slave and the output on the safety monitor being switched off. In decentralized
shutdown via a safe AS-i output, the response time is extended by the time that the safe AS-i
output needs in addition to the shutdown. The maximum response time is then at 70 ms.
Tested safety
The system has been tested and approved for use by TÜV (Germany), NRTL (USA), and
INRS (France). The transmission procedure for safety-oriented signals is designed in such a
way that the applications up to Category 4 in accordance with EN 954-1, up to PL e in
accordance with EN ISO 13849-1 and up to SIL 3 in accordance with IEC 61508 can be
implemented.

The configuration of safety technology is identical to the installation of AS-Interface that is
known today. The family of the safe AS-Interface products consists of the safety monitor,
which monitors or shuts down the safe nodes. The spectrum of safe nodes consists of the
safe modules and the safety-oriented sensors with integrated interface. Sensors, monitors
and safe AS-i outputs can be connected at any points of the AS-Interface network. More

Function
The safe nodes transmit their information according to the master call, like the standard
nodes, to the master. The safety monitor monitors this transmission from the safe nodes to
the master and switches into the safe state or transmits a shutdown signal to one or more
decentralized safe AS-i outputs, which on their part switch into the safe state. The safety
monitor enables various functions, such as OR logic, AND logic, timer functions, buffers, etc.
Software
With the ASIMON configuration software, the safety-oriented applications can be configured
and transferred to the monitor. The configuration consists of the input signals of the safe
nodes, the internal functions of the safety monitor as well as the assignment of the address
for the control of a safe decentralized output. The software also supports online diagnostics.

Integration
For the integration of the safety technology into AS-Interface, the existing infrastructure, like
the master and the power supply unit, can still be used. For the safety technology, the safety
monitor is integrated as a monitoring element and the safe nodes as an interface between
the safe sensors and the system. The safe sensors can be used as before. With ready-to-
use function blocks that are supplied with the ASIMON configuration software, a detailed
diagnosis of all parameterized blocks is possible. To do this, an AS-i address needs to be
assigned to the safety monitor via the configuration software. The evaluation is done via
function blocks in the PLC. Using preconfigured WinCC flexible blocks, this evaluation can
then be visualized on a system-wide basis on existing HMI devices (starting with OP/TP
270).

2.1.1 Functional principle
The basis for the safe switching of an actuator is the safety monitor. The functional principle
of the safety monitor is described in the AS-Interface System Manual, Edition 11/2008
Chapter 9.1. You can view or download the system manual here
(http://support.automation.siemens.com/WW/view/en/26250840).
The functional principle for safe switching of an actuator via a decentralized AS-i output
comprises four steps:
1. Acquisition of the safe signals via a safe input slave (e.g. Emergency Stop):
The safe slave transmits a safe code sequence (8x4 bit). For a safety-oriented
transmission of information, each safe input slave has a unique code sequence, which is
saved (by teaching) in the safety monitor during commissioning.
2. Evaluation of the safe signals by the safety monitor:
The function of the safety monitor is parameterized using the ASIMON configuration
software. During operation, the safety monitor compares the actual state of the received
code tables of all assigned safe input slaves with the stored desired state. According to
the evaluation of this safety information, the safety monitor switches its enabling circuit on
or off in a safety-oriented manner.
3. Forwarding the enabling or shutdown information to a decentralized safe output:
The enhanced safety monitor with integrated safe slave 3RK1105-1BE04-4CA0 or
3RK1105-1BG04-4CA0 is required for the forwarding of the enabling or shutdown
information. This optionally controls a safe AS-i output according to the switching state of
its second enabling circuit. For this purpose, the safety monitor emulates a safe slave,
which transmits a specific code sequence (7x4 bit) as a function of the state of the
second enabling circuit. In contrast to the code sequences of the safe input slaves, which
differ for each slave, the 7x4 bit code sequence for controlling a decentralized safe output
depends exclusively on the address assigned to the emulated slave. Teaching of the
code sequences as in the case of the safe input slaves is thus not necessary for safe
outputs.
4. Decentralized switching of the actuators via safe output slave:
The safe output slave evaluates as a passive listener the 7x4 bit code sequence which
the slave emulated in the safety monitor transmits. The address of the slave emulated in
the safety monitor is set in the safe output slave. This ensures a unique assignment
between safe output slave and safety monitor. If the safety monitor has enabled the
second enabling circuit, the safe output slave receives this information via the 7x4 bit
code sequence. If it is correctly received, the safe output slave activates the connected
actuator via its safe output. Thus, the safe output slave always assumes the same state
as the second enabling circuit of the assigned safety monitor.

Behavior during communication faults
If, as a result of a communication fault, the enabling signal does not arrive or does not arrive
correctly at the safe output slave, it shuts down its output as a safety measure. A fault
tolerance provided in the system thereby prevents the shutdown of the output during very
brief faults. After a fault, the user needs to acknowledge the fault for safety reasons.
In order to signal a shutdown after a fault to the user, the safe output slave also has an
integrated A/B slave. Via this slave, the waiting for an acknowledgment after a shutdown
because of a fault is communicated over the bus. If the user does the acknowledgment, the
safety monitor produces acknowledgment signals (help signals 1 and 2), which are
transmitted by specific modification of the 7x4 bit code sequence to the safe output slave. It
switches the actuator back on after receipt of the acknowledgment.

Generating the acknowledgment signals
For the acknowledgment after a communication fault, two different help signals are available.
In this context, a distinction is made according to the duration of the communication fault:
Communication faults >140 ms require help signal 1 (reset of error condition) as an
acknowledgment
Brief communication faults <140 ms require help signal 2 (restart) as an acknowledgment
This distinction enables the auto-acknowledgment of brief faults, because help signal 2
(restart) can also be transmitted continuously during operation. The conditions for
transmitting the help signals are parameterized in the ASIMON configuration software.
Configuration examples
With an enhanced safety monitor with integrated safe slave, a safe output slave can be
activated. In addition, the two relay outputs of the safety monitor can be used for local
shutdown.

To be sure any safety monitor can transmit only one shutdown or enabling signal for
decentralized safe shutdown. However, multiple safe output modules can also evaluate this
information together. Therefore, a safety monitor can jointly switch a group of safe output
slaves.

2.1.2 Overview
The safe ASIsafe SlimLine module S45F is used for safe switching of an actuator. For this
purpose, the device has a 2-channel safe output with which a safety-oriented shutdown up to
Category 4, SIL3 or PLe can be achieved. The device receives the enabling or shutdown
signal from the enhanced safety monitor with integrated slave. It simulates a safe slave,
which transmits a corresponding code sequence independently of the state of its enabling
circuit 2. The safe ASIsafe module S45F evaluates this code information and switches the
safe output accordingly.
In addition, the module has an integrated A/B slave. In addition to the diagnostics feedback,
this slave enables the functional switching of the enabling circuit and beyond that provides 3
digital inputs and 2 digital outputs.

2.1.3 Function
2 addresses are assigned to the S45F ASIsafe module for its operation. The safety-related
address is used for the assignment of the simulated slave of the safety monitor to which the
enabling circuit of the module is to react. The second address is needed for the standard
inputs and outputs, for the functional switching and for the device diagnostics. The address
is set according to the following sequence:
1. Setting the safety-related address. For this purpose set the switch on the front of the
device to F-ADDR.
2. Set the desired safety-related address via AS-i addressing device or AS-i master.
3. Check the set safety-related address:
Read the profile via AS-i addressing device or AS-i master.
The ID code must be "F".
The ID1 code must correspond to the tens digit of the address.
The ID2 code must correspond to the units digit of the address.
The IO code must be "7".
Example: Address 24 is set as a safety-related address.
The profile that is read must then be as follows:
ID-Code = F, ID1-Code = 2, ID2-Code = 4, IO-Code = 7
4. If the codes do not match, repeat steps 2 and 3. If the codes again do not match, replace
the device.
5. Set the device switch on RUN
6. Set the standard address (switch in position RUN):
Set the desired address via AS-i addressing device or AS-i master. No checking of the
set address is required.
The safety function is parameterized via the safety monitor using the ASIMON configuration
software. The ASIsafe module S45F always switches the enabling circuit identically to the
state of the enabling circuit OSSD 2 of the safety monitor. The S45F ASIsafe module is
assigned to the safety monitor via setting of the safety-related address. The response time of
the entire system (from the moment of the shutdown request on the safe input to the moment
at which the output has switched off) is at a max. of 70 ms (worst case). For the assignment
of the S45F ASIsafe module to the respective safety monitor, the same safety-related
address is set via the ASIMON configuration software in the safety monitor.

In addition, the enabling circuit of the S45F module can also be switched during operation.
The functional switching is activated via the parameter bit P1. Where:
P1 = 0 functional switching activated
P1 = 1 functional switching deactivated
(Default = deactivated)
If functional switching is activated, the enabling circuit via the output OUT3 of the integrated
A/B slave can be controlled via the AS-i master (the requirement is that the safe enabling
information from the safety monitor is correctly received).

System Manual, 09/2010, A5E03003228020-01 41
If the transmission of the enabling information is disrupted by the safety monitor, the module
safely shuts down the output. For a restart, a corresponding help signal is needed
independent of the duration of the communication fault. The following is applicable:
Duration of a communication fault >140 ms requires help signal 1 ("reset of error
condition")
Duration of a communication fault <140 ms requires help signal 2 ("restart")
The help signals are transmitted via the safety monitor using the code sequence of the
simulated safe slave. The conditions for transmitting the help signals are set during the
parameterization of the safety monitor in the ASIMON configuration software. In so doing, it
is possible to transmit the help signal 1 ("restart") continuously. Therefore, communication
faults up to 140 ms in duration can be automatically acknowledged.

software

The safe S45F SlimLine module has in addition to the safe output another 3 digital standard
inputs and 2 digital standard outputs. Mechanical contact elements and both 2- and 3-
conductor sensors can be connected to the digital inputs. One of the standard inputs can be
used for monitoring the protective feedback circuit. Actuators can be controlled
independently of the safety function via the digital standard outputs. The standard inputs and
standard outputs are controlled via the integrated A/B slave.
Note
In an AS-Interface network, which is controlled by the DP/AS-i F-Link 3RK3141.CD10, the
use of the S45F ASIsafe module is not permissible.

2.1.6.2 AS-i diagnostics of the integrated A/B slave
When there is an overload on the standard outputs and/or when there is an overload of the
sensor current supply of the standard inputs, the module sets the I/O error bit.
The safe S45 SlimLine module also maintains communication in the event of a sensor power
supply overload. In the event of a sensor overload, the substitute value zero is transmitted
for the inputs.
Note
This behavior ensures that an overload of the sensor power supply for the standard inputs
has no effect on the safety function of the device. Therefore, this is a departure from the
normal behavior of AS-i slaves, which revert to the reset state and then no longer
communicate via AS-Interface when there is an overload of the sensor power supply.

2.1.6.3 Diagnostic bit IN4 (DI3)
If the safe S45F SlimLine module has shut down the enabling circuit because of a
communication fault and is waiting for an acknowledgment in order to restart (help signal 1
or 2), the fourth input (input bit D3) of the integrated A/B slave assumes state 1. The request
for the acknowledgment signal is thereby transmitted to the controller and the safety monitor.
2.1.6.4 Diagnostics via ASIMON configuration software
In the ASIMON configuration software, the state of the safe output module can be displayed
in the online diagnostics via the "actuator diagnostics" diagnostics device. For this purpose,
a corresponding diagnostics device needs to be added in the ASIMON configuration for each
safe output module. The address of the integrated A/B slave of the safe S45F SlimLine
module as well as the diagnostics type need to be entered in it. Diagnostics type 4 is to be
selected for the safe S45F SlimLine module.
