Warning

Risks involved in the use of so-called SIMATIC–compatible modules of non-Siemens

ma-nufacture

“The manufacturer of a product

(SIMATIC

in this case) is under the general obligation to give

warning of possible risks attached to his product. This obligation has been extended in recent

court rulings to include parts supplied by other vendors. Accordingly, the manufacturer is obliged

to observe and recognize such hazards as may arise when a product is combined with products

of other manufacture.

For this reason, we feel obliged to warn our customers who use SIMATIC products not to

install so-called SIMATIC–compatible modules of other manufacture in the form of re-

placement or add–on modules in SIMATIC systems.

Our products undergo a strict quality assurance procedure. We have no knowledge as to wheth-

er outside manufacturers of so–called SIMATIC–compatible modules have any quality assur-

ance at all or one that is nearly equivalent to ours. These so–called

SIMATIC–

compatible mod-

ules are not marketed in agreement with

Siemens;

we have never recommended the use of so–

called SIMATIC– compatible modules of other manufacture. The advertising of these other man-

ufacturers for so–called SIMATIC–compatible modules wrongly creates the impression that the

subject advertised in periodicals,

catalogues

or at exhibitions had been agreed to by us. Where

so–called SIMATIC– compatible modules of non–Siemens manufacture are combined with our

SIMATIC

automation systems, we have a case of our product being used contrary to recommen-

dations. Because of the variety of applications of our

SIMATIC

automation systems and the large

number of these products marketed worldwide, we cannot give a concrete description specifical-

ly analyzing the hazards created by these so–called SIMATIC– compatible modules. It is beyond

the manufacturer’s capabilities to have all these so–called

SIMATIC–compatible

modules

checked for their effect on our

SIMATIC

products. If the use of so–called SIMATIC– compatible

modules leads to defects in a

SIMATIC

automation system, no warranty for such systems will be

given by

Siemens.

In the event of product liability damages due to the use of so–called SIMATIC–compatible mod-

ules,

Siemens

is not liable since we took timely action in warning users of the potential hazards

involved in so–called SIMATIC– compatible modules. ”

R 02/92 Application and Application Area

The

243 is a module for input and output, for preliminary processing, and forjumpering of ana-

log signals within short processing times. The

submodule

in its full configuration has eight quick

analog input channels with max. 35

psec.

conversion time, four input channels with analog value

conditioning and four analog output channels. Two comparators allow the comparison of analog

values with each other and via two value difference amplifiers, the signals can be amplified up to

20 times their original strength. All analog signals can be freely jumpered via soldering bases on

the circuit board. This means that as a user you can decide about the individual combinations of

the available hardware components.

Furthermore, eight digital inputs and eight outputs with direct bus access are available. Custom-

er–specific interrupt processing can be effected by means of the jumpering base.

The

243

submodule

can be used for the following programmable controllers:

– S5–115U/H

– S5–135U

–

s5–150s/u

– S5–155U/H

or expansion units (see section 6.1).

For the programmable S5–115U, an adapter casing is required. No fan assembly is required.

Dimensions and Mechanical Data

The

243 is a printed circuit board in double European format, with dimensions of 233.4 mm x

160 mm (DIN 41494). In accordance with the

SIMATIC

S5 compact peripheral system, the PCB

takes up one slot in the rack. It has a width of 1–1/3

SPS1

(20 mm). 42 Faston connector pins (2.4

mm x 0.8 mm) are located on the front plate. The bus connection is made via a second row,

48–way base connector. The base connector is located on the upper half. Ground

(Mext)

connec-

tion is provided via contact strips in the guide rails.

Overview of the Individual Variants

The

243 is available in one full–configuration version and two different part-configuration ver-

sions. The full–configuration module has the following independent functions:

– 1 Analog/digital converter, 8 channels, 12 bits, 35

psec.

conversion time,

bipolar or

unipolar

– 2 Digital/analog converters, 12 bits, bipolar

– 1 Digital/analog converter, 8 bits,

unipolar

– 1 Analog output amplifier

– 4 Analog value conditioning circuits with operating point and amplifier setting

– 2 Difference amplifiers (P controllers) with adjustable gain

– 2 comparators with

gating

logic connected in series, can be read in statically

and/orwith

inter-

rupt generation (interrupt evaluation is only possible for the

SIMATIC

S5–150U/S and

S5–155U

with externally-wired digital input module for interrupt generation).

– 8 binary inputs can be read in statically and/orwith interrupt generation (interrupt evaluation is

only possible for the

SIMATIC

S5– 150U/S and S5–155U with externally–wired digital input

module for interrupt generation).

– 8 binary outputs, 24 V, 200 mA, switching to P potential, not current–limited.

The inputs and outputs of the analog function groups are routed to the analog signal jumper

block. This makes it possible to combine the individual functions to suit user requirements. All

signals are nonfloating.

Function Description

3.3.2 Conversion of the Analog Input Signals

The central circuit of the analog input is the analog/digital converter which converts an applied

setpoint in a maximum of 35

~sec.

with a resolution of 12 bits. An analog eight–channel multiplex-

er is connected on the input side of the converter. The conversion of the analog input values takes

place in three stages:

1) Select the channel

2) Output the conversion command

3) Read the result

Select the channel:

The multiplexer is addressed under the module address +7. The channel to be converted

(O to 7) is selected by writing the three data bits 2°, 2

, and 2

Channel selection: (in the byte module address +7)

If the same channel is read in several times in sequence, it need not be selected each time. In

such a case it suffices when the active values are converted and read out. The selected chan-

nel remains current until a different channel number is written.

The current channel selected by the program is indicated by the three yellow LEDs on the mod-

ule front plate.

Output the conversion command:

The conversion command is given by writing the module address +6, whereby the written data

is irrelevant.

Read the result:

The result can be read immediately in the peripheral word module address +6 as the “Ready”

signal is only generated when the ADC has completed the conversion (i.e., after a maximum of

psec.).

No additional waiting time is required. It is also possible to process other parts of the

3.4.1 Jumpering of Analog Output

Five channels are available (AO1 to

which can be freely distributed via the soldering base. It

is possible to output analog values (provided by the D/A converters) on a certain channel, and

transfer this signal simultaneously to different outputs. In the same way, for instance, the outputs

of the difference amplifiers (P controllers) or conditioned analog values can be directly output as

analog values. Attention must be paid to the input side of the analog output

A05

to make sure that

an analog amplifier is connected. It is not only able to amplify the value provided by DAC3, but also

a value which, via an analog input, is present as an actual–value conditioning input on the P con-

troller. Three digital/analog converters, which are described in more detail below, convert binary

values into analog signals.

3.5 Analog Value Conditioning Circuit

3.5.1 Operating Elements

The four inputs of the analog value conditioning circuits are meant to standardize the voltages

provided by encoders to the O V to +10 V range, and are conditioned in accordance with the set-

ting of the trimming potentiometer on the module front plate. Conversion in the O to +10 V range is

not possible unless input voltage > –4 V. Conditioning is always necessary when negative volt-

ages are processed and routed via the comparators. The

comparators are designed for positive voltages so that the input voltages must be transformed to

the positive range.

In addition to the 4 trimming potentiometers for setting the amplification and the offset, there are

four measuring sockets on the front plate via which the conditioned analog values can be

scanned. A socket (socket 6) is also available. This socket is connected to analog ground M

ari

This socket can be used as the ground connection for a graphic recorder which records the condi-

tioned analog signals.

Attention: Socket5 hasnofixed internal connection toaspecificsignal. Itis located

on the analog–signal

space AR32. This socket is free for

switching, either for a signal from an

3.5.2 Functioning

On the front plate of the

243 there is one trimming potentiometer per input (AV1 to AV4) for the

offset of the operation point by a binary amount between –2 V and +2 V and for setting the amplifi-

cation (gain) as a factor in the range from 1 to 10.

First, the active analog value is multiplied by the fixed factor 0.5 specified by the module. Then, the

set offset is added, and finally this value is multiplied by the desired gain factor. The possible total

gain is between 0.5 and 5.

other side.

There are many possibilities for setting the trimming potentiometers. The user decides which con-

3.6 Comparators and

Gating

Logic

3.6.1 Input Signal Range and Possible Circuitry

The two comparators are designed to compare positive voltages in the range of O V to +10 V. If

negative input voltages need to be compared, they must be routed through the analog value con-

ditioning circuit and converted to a positive value.

The inputs of the comparators are connected with analog–signal jumpering via a filter circuit

(AR17 to

AR20).

Depending on the application, the comparator inputs can be connected with two signals each that

are routed through the soldering base.

Via

gating

logic, the current comparator status can be read in, and/or an interrupt can be gener-

ated.

In case of interrupt processing, be aware that a hardware interrupt, fed

directly from the module to the bus, can only be processed by the con-

trollers S5–115U/H and S5–135U with CPU 922 or CPU

928AJB.

of the status of the comparators and

logic is dependent on the evaluation of “bits” A, B, C,

Interrupt Processing

General Conditions for Interrupt Processing

This section now covers specific characteristics of interrupt processing in relation to the individual

programmable controllers. Interrupt

jumpering

on the

243 is described in section 5.7.

An interrupt can only be triggered by the comparators or the

gating

logic on the output side. The

condition for generating an interrupt is its enable by the signal STROBE. The corresponding pa-

rameter assignment is described in section 3.6, as well as a description of the switching of

gating

logic between rising edge and falling edge (signal LOG).

This makes alarm processing only possible when the

243–lAA.. module is fully

configured.

4.2 Possibilities for Interrupt Processing

In principle, interrupts can be evaluated in any programmable controller which allows operation

with the

243. In practice, however, this evaluation depends on the type of controller. Only with

the S5–115U/H and

S5–135U

with CPU 928A/B or with CPU 922, is direct access to the bus with

interrupt lines possible. For all other programmable controllers, a separate digital input module

with interrupt–generating capability must be used. This module must be externally wired with the

binary outputs of the

243.

4.3 Direct Bus Access

Direct access to the interrupt lines is only possible for programmable controllers with

edge–

triggering. This means that the central unit reacts only to edge changes without regard to specific

status levels. This applies to allCPUSoftheS5–115U/H series, CPU 922 and the

928NB

CPUS of

the

S5–135U

series. If interrupts are triggered via direct bus access, the memory latch

may

be exchanged for the soldering base D9, included with delivery.

Interrupt Processing in the

S5-l15U/H

In the S5–115U with CPU 941A, interrupt lines

~Aand

are available for CPU

941B,

942–7UH....

From CPU 942A/B on, the four interrupt

lines-~~,

~B,

and

~Don,

which in-

terrupts can be initiated, are available. The two pins

IRF

and

~Gon

the

interrupt–jumper~g

block

X19may

not be used; they must always be grounded on M (pin 6). The same applies to

IRC

and

~Dwhen

CPU 941A is installed. Furthermore, all process interrupts which are not used must

be connected to grounding M. An organization block is allocated to each interrupt in the

S5–1 15U. The organization block must be programmed for interrupt evaluation. The following

relations apply:

Interrupt

– OB 2

Interrupt

– OB 3

Interrupt

– OB 4

Interrupt

– OB 5

Each interrupt line should be allocated to only one interrupt–generating

243. In the case of

several accessing modules, it would require considerable software effort to determine which

243 triggered an interrupt (no evaluation possible via peripheral byte

O!).

Attention;

Interrupt requests can be processed only in the central unit. The

interru

t program structure and

interrupt–OB

handling are found

in the 5–115U manual or the S5–115H manual.

Exception:

Alarm processing in the expansion device is possible with EG 701 –3

(from release

6ES5

701–31A13) or EG

186U,

when

Iigth

wave conductor

interfaces 6ES5307–3UA1 1 and

6ES5

317–3UA11 are used.

Example:

The two analog input channels AlO and All are compared with each other by comparator 1

(AIOto

+Comp.

and All to

-Comp.).

As soon as All exceeds the value of AIO, this is indicated by

a signal light connected to the binary output B02 of the

243. At the same time channel A13 is

read in once in the interrupt program. The module starting address is given as 144, and interrupt

line

~Bisselected.

Only in the case of parameterization for falling edge can a reasonable evalua-

tion of the interrupt request be made.

4.3.2 Interrupt Processing in the

In the multiprocessor system S5–135U, the four interrupt lines

~A,

~B,

allocated to one CPU slot per tine:

CPU

IZRl

CPU 2 – Interrupt

An interrupt organization block OB 2 can be filed in each of the central modules.

Pttent

;

The presetting of data block DX O for “edge-triggered interrupt process-

ing” is mandatory to work with direct hardware interrupts. In the

S5–135U,

interrupt processing is also only possible in the central rack.

Exception:

Alarm processing in the expansion device is possible with EG 701–3

(from release 6ES5 701–3M13) or EG

Only

243 should access an interrupt line. Otherwise, no evaluation or only limited

evaluation is possible (see also section 4.3.1).

See the appropriate equipment manual for a description of interrupt handling in the S5–135U with

CPU 922 or CPU 928A/B.

The S5–135U is operated with two central processors, (i.e., a

(KF = +5000). As soon as the two analog input channel values exceed the correlated “setpoints”,

an interrupt is generated. In case of an interrupt from

gating

logic 1,

AV1

is read in at the ADC of

CPU 922 and a check is made to see

ifthe

4.4 Separate Interrupt Input Module

If a programmable controller is designed for fundamental mode operation (level–triggered

mode), i.e., the CPU only reacts when a certain level is active on the interrupt lines, or if a control

without interrupt lines on the S5 bus is involved, interrupts can only be evaluated by means of a

separate binary input module with process interrupt generation. The

CPUS

of systems

S5–135U

(CPU 922 and CPU 928A/B when

parameterized

accordingly) and S5–155WH oPerate in

level–triggered mode. For devices without interrupt lines, the interrupt scan is made via the input

byte O. This applies to the

S5–150S

and

S5–150U

controllers. If interrupt processing is desired

for one of the aforementioned systems, replace the memory latch

on the

243 with the

soldering base

D9,

included with delivery. In addition an interrupt module is required.

4.4.1 Interrupt Processing in the

S5–135U

In the S5–135U programmable controller, both CPU 922 and CPU 928A/B operate in

level–

triggered mode. The

CPUS,

however, can also be

parameterized

for edge–triggered processing.

In case of level–triggered operation, the digital input module6ES5432–4UA11 must be addition-

ally inserted. On the

243 module, the comparator outputs and the interrupt–generating out-

puts of the

gating

logic must be jumper–connected to the soldering base

D9,

which in turn is

connected with the binary outputs of the

243. Furthermore, the jumper connections on the sol-

dering base X19 (pins 11, 12, 13, 14, 15 and 16 connected to grounding M, pin 6) may not be

changed from their original delivery condition. Then the binary outputs are externally connected

to the inputs of the interrupt module. The interrupt triggering is handled exclusively by the module

6ES5432-4UA1 1. A description is found in the appropriate equipment manual.

When working with a separate interrupt input module, the

243 can

operate from any

slot, whether in the central unit or in an expan– sion

unit. The interrupt module 6ES5432–4UA1 1, however, must always be

inserted in the central unit.

Several interrupts from one

243 or from different IPs 243 can be routed to a digital module with

the capability of process interrupt generation.

Example:

In the

S5–135U

with CPU 922the two analog input values AIOand All are applied tothe difference

amplifier. The amplifier output runs to +comp. and is compared with –comp. which is connected

to the input

A16.

If the value at the

A16

channel exceeds the output voltage at the difference amplifi-

er, an interrupt is generated and a value which was previously filed in FW 120 is output at A02 via

DAC2.

The module address is given as 160; parameterization is for falling edge.

4.4.2 Interrupt Processing in the

S5–150U/S

The systems

S5–150U/S

have no interrupt lines. In this case an interrupt signal is only possible

via evaluation of the peripheral byte O. For details of this procedure seethe appropriate equipment

manual.

An interrupt OB is allocated to each bit of the input byte O, as follows:

10.0 – OB 2

10.1 – OB3

10.2 – OB 4

10.3 – OB 5

10.4 – OB 6

10.5 – OB 7

10.6 – OB 8

10.7 – OB 9

In case of a signal change for a bit of IBO, a branch to the correlated interrupt block takes place.

Generally an interrupt module is used for interrupt generating (for the

S5–

150U this is the module

6ES5432–4UA1 1, and for the

S5–

150S it is the module6ES5432–3BA11 ). See the appropriate

equipment manual for specifications and operation.

On the

must be replaced by the soldering base

D9.

The

interrupt–generating outputs of the

gating

logic are connected with the binary outputs BOO to

B07 via the soldering base

D9.

Then the outputs are externally connected with the inputs of a

binary input. The solder connections on soldering base Xl 9 remain in their original delivery state

(all interrupt lines to grounding M).

Attention:

With

the

systems

S5–150U/S,

interrupt

processing is only possible in an

expansion rack. The same applies to the use of IPs.

All interrupt–generating modules must be located in the same expansion rack.

Example:

In theS5–150U an

243 is operated under the following conditions:

A value stored in

EJ!Y

78 is output on DAC2 and stored on the difference amplifier. Difference + is

connected with

AV3.

The amplifier output value is compared with the analog input channel

A15

at comparator 1, whereby

A15

is also read in on

ADC.

A15

is less than the value of the signal at

+comp,

A12

is first converted three times, then AV4 twice on the

ADC.

The module address is

given as 240; parameterization is for rising edge.A6ES5432-4UA11 interrupt module is used

and parameterized accordingly.

Interrupt Processing

4.4.3 Interrupt Processing in the

S5–155U/H

With the S5–155U, the evaluation of interrupts is accomplished the same way as with the

S5–150U/S

(i.e., by scanning the input byte O

[S5–150U

mode]). The

S5–155U

system offers

the additional possibility of interrupt requests via interrupt lines, but it cannot be put to use directly

in connection with the

243, as the hardware interrupts operate in level–triggered mode.

Proceed as described in section 4.3.2 when using a CPU 922 or a CPU 928A/B

(edge-

triggered) in PLC

S5-155U.

Indirect operation via the interrupt lines is possible, if the parameters in DX O were assigned

accordingly. This is only possible with an interrupt–capable, digital–input module to which the

desired

243 signals are routed externally. The blocks OB 2 to OB 5 are defined as interrupt

blocks (S5-150U/S mode).

If interrupt evaluation in this manner is desired, see the S5–155U or S5–155H equipment

manual.

The evaluation of the input byte O is accomplished in the same way as in the

S5–

150U/S systems;

for each bit of input byte O, an interrupt OB is allocated where the respective interrupt reaction is

filed.

A process interrupt is always initiated by a binary input (e.g., from the interrupt module

6ES5

432–4UA11. Again, this input is set by one of the binary outputs of the

243. On the

243, the

memory latch D9 must be exchanged for the soldering base

(included with delivery), which

serves as a connecting link between the binary signal/interrupt jumpering and the binary outputs.

The jumpers between the interrupt–line pins and the grounding contact M may not be altered

from their factory-delivered condition.

Attention: Operation of the

243 and of the interrupt module 432-4 is possible in

the central or expansion rack. The

243 and the interrupt module can also

be located in different module racks.

Example:

In the

S5–

155U system, the difference amplifier 2 of an

243 is connected to a conditioned ana-

log value

AV1

and to the analog input channel A15. The output of the difference amplifier is

checked for exceeding or dropping below certain values. If the output exceeds a value furnished

by DAC2, previously filed in FW 190, then the output of the difference amplifier and the input

chan-

nel

AV1

are read in at the ADC and stored in the flag area. Depending on the signal status of the

binary input B12, either KF = +800 (status “O”) or KF = +1000 (status “l”) is active at DAC1. If the

respective value drops too low, a voltage of 5.85 V is output at

DAC3.

The module address is given

as 176; parameterization is for falling edge.

On the module 432–4, the presetting must be set according to the operating instructions.

5.6 Jumpering of the Binary Signals

The binary signals are also conducted via a soldering base and can be interswitched in a

user–

specific way. If desired, the interrupt evaluation is also activated via the binary signal

jumpering.

The digital inputs and outputs can be directly read in or read out via the bus. For interrupt

processing, however, jumpers must be installed on the soldering base X19. The following

diagram shows the structure of the binary signal

jumpering:

5.7 Interrupt

Jumpering

If an interrupt evaluation is intended, this is possible with the programmable controllersS5–11 5U/

H and

S5–135U

with CPU 928A/B or CPU 922 (or same CPUS in PLC

S5–155U)

via direct bus

access to the interrupt lines. All other control devices require an additional binary input module

with process interrupt generation and external wiring. In this case, the intermediate memory latch

D9 must be replaced with the soldering base D9, included in the delivery. A detailed description of

the procedures for interrupt processing with the

243 is given in section

Here, reference is

made only to the pin assignment of the soldering base relevant to the

jumpering

of interrupts.

5.8 Setting the Module Address

The module address is set via the DIP FIX switch on the soldering base X2 (see the layout of setting

elements in section 5.4). Addressing in the 1/0 area is between the starting addresses 128 and

248. The address displacement is 8 (i.e., a maximum of 16 modules can be addressed).

Example:

First starting address 144

Second starting address 152

It should be noted that when the

243 is used in a central rack (S5–115U/H, S5–135U or

S5–155U/H), the jumper A–B must be closed. In an expansion device, the jumper A–B I?WX

remain open.

The soldering base X2 appears as follows:

when the module is a dressed in Q area.

Attention: Only the programmable controllers S5–135U, S5–150U/S

are capable of addressing the Q area. The module must be

inserted in an expansion rack. The Q area comprises the start adresses

7.2 Function Block FB 160

(PER:ANL)

7.2.1 Function Description

The function block “Read analog module” (when the module is outfitted accordingly) accepts the

selected analog value and outputs it either as a bit pattern, the way it arrives from the module, or as

a 16–bit fixed point numeral, standardized to the respective nominal value.

Furthermore, the binary inputs and the comparator outputs can be read with this function block.

Prior to reading the comparator outputs, the

gating

logic is switched over.

Function

FB 160 reads the analog and binary inputs, switches over the

gating

logic and reads the com-

parator outputs.

7.2.7 Function Block Application

The module basic address and the channel number for the analog value are specified by parame-

ter BGKN. Depending on the channel number, the function block reads an analog value from the

module and outputs it at parameter

ADC.

The representation of the analog value depends on the NORM parameter:

NORM = “O”:

The analog value read at the module is output unchanged at parameterADC (as a

bit pattern according to the description in the operating instructions).

NORM = “1“

The analog value read at the module is converted to the nominal range. The nomi-

nal range is defined by the values at parameter

The conversion formulas are:

for BT = O (Nominal range O V to 10 V):

20000

ADC

= rough value x

~192

for BT = 1 (Nominal range –10 Vto +10 V):

20000

ADC

= rough value x

~096

for BT = 2 (Nominal range –5 V to +5 V):

20000

ADC

= rough value x

~192

The analog value is output as a 16–bit fixed–point numeral for the unit

mv.

When parameter DE–L has the signal status”1”, the binary module inputs are read and then out-

put at parameter DE. If the module has no binary inputs, signal status “O” is output to all bits.

When parameter KP–L has the signal status”1”, the comparator outputs of the module are read

and then output at parameter

KOMI?

The bits now required, LOG and

STR,

are set in accordance

with the parameters LOG and

STR,

and they are transferred to the module during channel selec-

tion.

DAC

depends on the signal status at parameter NORM:

NORM = “O”:

The bit pattern at parameter

DAC

(in the case of channel 3, the left byte) is trans-

ferred to the module unchanged (bit assignment as shown in the operating in-

structions).

NORM = “1“:

The value at the parameter is interpreted as a standardized 16–bit fixed–point

number (nominal range with KN = 1 or 2:

10000 mV; with KN = 3: O to 10000

rev). Depending on the channel number KN, the analog value is computed ac-

cording to the following formula:

For channel number 1 or 2:

13422

Analog value =

DAC

x —

65536

For channel number 3: 1678

Analog value =

DAC

x —

65536

If the value is outside the currently valid nominal range, it is limited to an extreme

value.

If the parameter DA-S has signal status”1”, the value at parameter DA is transferred to the binary

module outputs. If the module has no binary outputs, the command is ineffective.

This example shows the operation of the analog module 1P 243. By means of a simulator the indi-

vidual functions can be selected (via binary inputs). The signal states can be displayed via binary

outputs. The display shows how an analog value applied to the module can be read and how an

analog value can be output via the module.

This example also shows the necessary jumper settings and wiring requirements for the

mo-dule.

Therefore, it can also be used as a test program to check the jumper settings and functions of the

module.

7.4.3 Assignment of the Inputs and Outputs

The program is designed in a way that allows easy adaptation to different input and output assign-

ments. The program block (PB 243) that contains the test program works with flags only. The in-

puts and outputs to be used are allocated to these flags by organization block OB 1.

In the example the flags are the input word

IW4

and the output word

QW4

or the input word

7.4.4 Turn-On, Start-Up Behavior

The program is loaded entirely from the floppy disk to the user memory of the programmable con-

troller.

During start-up there is no need to supply any data to the analog module. Its ready state is indi-

cated by the green LED on the front panel. The LED lights up when an external 24 V voltage is

applied.

If at the time the programmable controller is turned on, all simulator inputs are in switch position

“O”, no outputs maybe set after the start-up of the programmable controller.

If one of the outputs Q 6. O/Q 10.0 (flag F 14.0) or Q 6.1/Q 10.1 (flag F 14.1) is set, a

para-meteriza-

tion error was made. The exact error cause can be identified at flag byte FY 16 (for the

parameterization error shown for output Q 6. O/Q 10.0) or at flag byte FY 17 (for the

parametrizat-

ion error shown for output Q 6.1/Q 10.1). Both flag bytes are set in accordance with the error bytes

FY 255 of the standard function blocks FB 160 and FB 161.

7.4.5 Reading the Binary Inputs

If input 14.1 is brought to switch position”1”, the binary inputs connected to the analog module

are displayed at output byte

QB4/QB8.

If the signal status of these inputs is modified, the display

on the simulator is modified accordingly.

7.4.6 Reading the Analog Value

The channel numbers from O to 7 are specified via the parameter BGKN of function block FB 160.

The LEDs on the module’s front plate indicate the currently selected channel as a bit pattern.

The analog value read in the example is transferred to the module through the front panel connec-

tor via input

IW1

(contact 24) and the appropriate potential contact (contact 23). It can be meas-

ured simultaneously at sockets 1

(IW1)

and 6

(ManJ.

The output for analog value acquisition

AV1

(Pin 16) must be brought to channel O of the ADC (Pin 1) via analog value

jumpering.

The analog value read by function block FB 160 is output in flag word FW 10. Via the programmer

function “Control Variable”, the actual value can be displayed directly.

If input 14.0 (“NORM”) is brought to switch position”1”, the analog value is displayed in

given

in binary code (ranging from –1 0000 to +10000).

Othetwise

it is given as a bit pattern, the way it

arrives from the module.

Via the two potentiometers “Work point

AV1”

and “Amplification

AV1”,

the analog value can be

changed. In order to check whether the module reproduces the applied value in correct form, the

amplification should be set to value”1” and the work point to “O”. For this purpose a firm value

(e.g., 2

should be specified at the analog value input

AV1.

Then a reading should be taken at the

sockets and the amplification changed until the input value matches the end value. The work point

is set by zero adjustment (i.e., the applied and the measured voltages are both zero). Via soldered

jumpers the individual voltage ranges can be set as follows:

UNI

– 10V

(BT

= O: Voltage range from O V to 10

– 20 V

(BT

= 1: Voltage range from -10 Vto +10

– 10V

(BT

= 2: Voltage range from -5 V to +5 V)

7.4.7 Checking the Comparators

routing of analog values has not been completed, the output for analog value acquisition

AV1

(Pin 16) must be connected with the “+” input of comparator 1 (Pin 20). Furthermore, the output

for analog value acquisition

AV2

(Pin 15) must be connected with channel 1 of the

ADC

(Pin 2) and

with the “-” input of comparator 1 (Pin 19).

Channel O is set to 2

Depending on whether the analog value measured at channel 1 is below or

above 2 V, there will be different states of the comparator outputs (in this case A and B for com-

parator output 1).

The function KP–L “Read comparator outputs” is switched on via input 14.2. Depending on the

status of the LOG bit (I 4.3), the following signal states will result for comparator output 1:

LOG (1 4.3)

“

o“

“ “

Channel 1<2 V

A = “O”, B = “1“

A = “1“j B = “l”

Channel 1>2 V

A = “l”, B = “1“

A = “1“, B = “O”

The comparator outputs are conducted to the output byte

QB5/QB9

and are displayed there. In

this case “A” corresponds to output Q 5. O/Q 9.0 and “B” corresponds to Q 5.1/Q 9.1. After turning

off the function “Read comparator outputs”, the outputs at the simulator remain active. Via input

4.7 (flag F 4.7) the outputs can be reset.

7.4.8 Writing the Binary Outputs

When the function “DA-S Write

binaty

outputs” (1 4.6) is activated, the binary outputs of the ana-

log module, connected to the simulator, are indicated by LEDs on the simulator.

The binary outputs are entered at input byte IB5.

7.4.9 Writing the Analog Value

When the analog routing operations have been performed in single steps so far, they now must be

supplemented by the following jumpers:

DAC1

–>AOI

(PIN 21) (PIN 25)

DAC2

–> A02

(PIN 22) (PIN 26)

DAC3

–>

A03

(PIN 23) (PIN 27)

Via the programmer function “Control variable” a value can be specified via flag word FW 12 which

is output as an analog value. If input 14.0 (NORM) has signal status”1”, the value can be output in

in binary form (ranging from –1 0000 to +10000). Otherwise the bit pattern is required and is

then directly transferred to the module.

In order to determine the written analog value, it is measured at the contacts in the front connector

of the analog module (e.g., pin 28 for

AO1

and pin 33 for potential).

The propagation times for these three commands must be added to the converting times of a

per channel to obtain the time required for reading in an analog input

channel.

If the same channel is converted in repeated sequence, the command “ADC

channel select” can be omitted, as the selected channel remains active after the call until it is

overwritten.

Attention:

Not only the channel, which is selected by the multiplexer and then converted by the

ADC,

is stored in byte “subaddress

but also the desired states of the “LOG” and
