3.1
Basic information on Ethernet switching
Ethernet switching
Ethernet switches forward data packets directly from the input port to the appropriate output
port during data exchange based on the address information. Ethernet switches operate on a
direct delivery basis.
Essentially, switches have the following functions:
● Connection of collision domains / subnets
Since repeaters and star couplers (hubs) operate at the physical level, their use is
restricted to the span of a collision domain. Switches connect collision domains. Their use
is therefore not restricted to the maximum span of a repeater network. On the contrary,
extremely large networks with large spans are possible with switches.
● Containing load
By filtering the data traffic based on the Ethernet (MAC) addresses, local data traffic
remains local. In contrast to repeaters or hubs, which distribute data unfiltered to all ports
/ network nodes, switches operate selectively. Only data intended for nodes in other
subnets is switched from the input port to the appropriate output port of the switch. To
make this possible, a table assigning Ethernet (MAC) addresses to output ports is
created by the switch in a "teach-in" mode.
● Limiting errors to the affected subnet.
By checking the validity of a data packet on the basis of the checksum which each data
packet contains, the switch ensures that bad data packets are not transported further.
Collisions in one network segment are not passed on to other segments.
The need for Industrial Ethernet switches
With over 95% of LANs based on Ethernet, this is the most commonly used technology. The
use of switches is particularly important. They allow extensive networks with large numbers
of nodes to be set up, increase the data throughput, and simplify network expansion.
The modular IE Switches X-400 from SIMATIC NET are designed for use in high-speed plant
networks that will also meet future requirements. Thanks to their modular design, the
IE Switches X-400 can be adapted to the task in hand in terms of number of ports and
transmission medium. Due to support of IT standards such as VLAN, RSTP, IGMP, and
GARP makes seamless integration of automation networks in existing office networks
possible.
The devices are designed for use in switching cubicles and cabinets.

Technical options (network topologies)
The modularity of IE Switches X-400 simplifies the expansion of a network regardless of the
network topology.
You can use an IE Switch X-400 in the following network topologies:
● Linear structure
● Star/tree structure
● Ring with redundancy manager
The maximum cable length is 70 km for single mode Fast Ethernet transmission and single
mode gigabit transmission. Mixed operation within the topology, for example between
SCALANCE X414-3E and OSMs/ESMs is possible regardless of the structure being used
(ring with redundancy manager, star, or linear structure).
Using an IE Switch X-400 as the redundancy manager in a ring with redundancy manager
provides greater availability. If there is an interruption on the connection between these
switches, the IE Switch X-400 used as redundancy manager acts like a switch and in a very
short time creates a line from the ring with redundancy manager. As a result, a functional,
end-to-end structure is restored. For more detailed information, refer to the configuration
manual "SCALANCE X-300 and SCALANCE X-400 Industrial Ethernet Switches".

3.2.3
Ring with redundancy manager
To increase the availability, optical or electrical linear topologies of up to 50 switches
(IE Switches X-400, SCALANCE X-200, or OSM/ESM) can be closed with a SCALANCE
X414-3E or SCALANCE X408-2 to form a ring.
Functional description
The two ends of the bus are closed to form a ring by an IE Switch X-400 operating as a
redundancy manager.
Table 3- 5 Redundancy manager setting
SCALANCE X414-3E
SCALANCE X408-2
The redundancy manager function is enabled or
disabled by DIL switches on the CPU module or
by configuring with CLI or WBM.
The redundancy manager function is enabled by
the SELECT/SET button or implemented by a
setting in the software (CLI or WBM).
For more detailed information, refer to the
configuration manual "Industrial Ethernet
Switches SCALANCE X-300 SCALANCE X-400".
In contrast to the ring ports of the other switches, the ring ports of the redundancy manager
are disconnected when the network is operating problem-free. The IE Switch X-400
operating in the redundancy manager mode monitors the connected bus over its ring ports
and switches the ring ports through if there is an interruption on the connected bus; in other
words, it restores a functioning bus over this substitute path. Reconfiguration is achieved
within 0.3 s. As soon as the problem is eliminated, the original topology is restored; in other
words, the ring ports in the redundancy manager are disconnected from each other again.
In a ring with redundancy manager, there can only be one switch configured as a
redundancy manager.
(Default ports 5.1 and 5.2. Both the RM and the switches in the ring must be connected over
these ring ports to allow redundancy to function.)
Electrical ring ports
An electrical ring with redundancy manager can be set up without media modules since the
basic device provides connectors (RJ-45 jacks) that allow attachment of electrical (twisted
pair) connections (10, 100, 1000 Mbps). The factory setting defines the two ports on slot 5 as
ring ports.

Optical ring ports
An optical ring with redundancy manager is only possible with media modules.
Which slots or ports should be used, depends on the selected transmission rate. The ports
that can be used as ring ports are located on the media modules that can be used in the
following slots (see table).
As an alternative to optical gigabit transmission, the following ports (see table) can also be
configured as ring ports for an optical Fast Ethernet connection.

Options of media redundancy
There are various options available to increase the network availability of an Industrial
Ethernet network with optical or electrical linear bus topologies:
● Mesh networks
● Parallel connection of transmission paths
● Closing a linear bus topology to form a ring topology
3.2.5
Media redundancy in ring topologies
Structure of a ring topology
Nodes in a ring topology can be external switches and/or the integrated switches of
communications modules.
To set up a ring topology with media redundancy, you bring together the two free ends of a
linear bus topology in one device. Closing the linear bus topology to form a ring is achieved
with two ports (ring ports) of a device in the ring. This device is the redundancy manager. All
other devices in the ring are redundancy clients.
Figure 3-6 Devices in a ring topology with media redundancy
The two ring ports of a device are the ports that establish the connection to its two
neighboring devices in the ring topology. The ring ports are selected and set in the
configuration of the relevant device. In STEP 7 and on the S7 Ethernet CP modules
themselves, the ring ports are indicated by an "R" after the port number.
Note
Before physically closing the ring, download the configuration of your STEP
7 project to the
individua
l devices.

How media redundancy works in a ring topology
When using media redundancy, the data paths between the individual devices are
reconfigured if the ring is interrupted at one point. Following reconfiguration of the topology,
the devices can once again be reached in the resulting new topology.
In the redundancy manager, the 2 ring ports are disconnected from each other if the network
is uninterrupted. This prevents circulating data frames. In terms of data transmission, the ring
topology is a linear bus topology. The redundancy manager monitors the ring topology. It
does this by sending test frames both from ring port 1 and ring port 2. The test frames run
round the ring in both directions until they arrive at the other ring port of the redundancy
manager.
An interruption of the ring can be caused by loss of the connection between two devices or
by failure of a device in the ring.
If the test frames of the redundancy manager no longer arrive at the other ring port, the
redundancy manager connects its two ring ports. This substitute path once again restores a
functioning connection between all remaining devices in the form of a linear bus topology.
As soon as the interruption is eliminated, the original transmission paths are established
again, the two ring ports of the redundancy manager are disconnected and the redundancy
clients informed of the change. The redundancy clients then use the new paths to the other
devices.
The time between the ring interruption and restoration of a functional linear topology is
known as the reconfiguration time.
If the redundancy manager fails, the ring becomes a functional linear bus.
Media redundancy methods
The following media redundancy methods are supported by SIMATIC NET products:
● HRP (High Speed Redundancy Protocol)
Reconfiguration time: 0.3 seconds
● MRP (Media Redundancy Protocol)
Reconfiguration time: 0.2 seconds
The mechanisms of these methods are similar. HRP and MRP cannot be used in the ring at
the same time.

3.2.6
MRP
The "MRP" method conforms to the Media Redundancy Protocol (MRP) specified in the
following standard:
IEC 62439-2 Edition 1.0 (2010-02) Industrial communication networks - High availability
automation networks Part 2: Media Redundancy Protocol (MRP)
The reconfiguration time after an interruption of the ring is a maximum of 0.2 seconds.
Requirements
Requirements for problem-free operation with the MRP media redundancy protocol are as
follows:
● MRP is supported in ring topologies with up to 100 devices. Exceeding this number of
devices can lead to a loss of data traffic.
● The ring in which you want to use MRP may only consist of devices that support this
function.
These include, for example, some of the Industrial Ethernet SCALANCE X switches,
some of the communications processors (CPs) for SIMATIC S7 and PG/PC or non-
Siemens devices that support this function.
● All devices must be interconnected via their ring ports.
● "MRP" must be activated on all devices in the ring (see "MRP configuration").
● The connection settings (transmission medium / duplex) must be set to full duplex and at
least 100 Mbps for all ring ports. Otherwise there may be a loss of data traffic.
– STEP 7: Set all the ports involved in the ring to "Automatic settings" in the "Options"
tab of the properties dialog.
– WBM: If you configure with Web Based Management, the ring ports are set
automatically to autonegotiation.

Topology
The following schematic shows a possible topology for devices in a ring with MRP.
Figure 3-7 Example of a ring topology with the MRP media redundancy protocol
The following rules apply to a ring topology with media redundancy using MRP:
● All the devices connected within the ring topology are members of the same redundancy
domain.
● One device in the ring is acting as redundancy manager.
● All other devices in the ring are redundancy clients.
Non MRP-compliant devices can be connected to the ring via a SCALANCE X switch or via
a PC with a CP 1616.

HRP
The "HRP" media redundancy method allows a reconfiguration time of 0.3 seconds following
an interruption in the ring.
Requirements
The following conditions must be met for problem-free operation with HRP:
● HRP is supported in ring topologies with up to 100 devices. Exceeding this number of
devices can lead to a loss of data traffic.
● The ring in which you want to use HRP may only consist of devices that support this
function. This applies, for example, to the following devices: X-400 IE switches, X-300
IE switches, X-200 IE switches and OSM/ESM.
● All devices must be interconnected via their ring ports.
● A device in the ring must be configured as redundancy manager by selecting the "HRP
Manager" setting. You can do this with the button on the front of the device, Web Based
Management, CLI or SNMP.
● On all other devices in the ring, either the "HRP Client" or "Automatic Redundancy
Detection" mode must be activated.
You can do this with Web Based Management, CLI or SNMP.
● In the basic status, the "HRP Client" or "Automatic Redundancy Detection" mode is set as
default.

Redundant coupling of network segments
Redundant coupling of network segments
The example of the redundant linking of two network segments shown here, for example
rings with redundancy manager (HRP only), can be implemented homogeneously with
SCALANCE X414-3E or SCALANCE X408-2 or mixed with SCALANCE X414-3E and
SACLANCE X408-2. Reconfiguration time 300 ms.

Figure 3-8 Redundant coupling of two subnets in mixed operation with SCALANCE X414-3E and
SCALANCE X408-2
In this case, network segments are rings with a redundancy manager (RM). The rings can
also be interrupted at one point (linear topology).
For a redundant link as shown in the figure, two devices must be configured within a network
segment. This configuration is set in Web Based Management, Command Line Interface or
using SNMP access. For more detailed information, refer to the configuration manual
"SCALANCE X-300 and SCALANCE X-400 Industrial Ethernet Switches". The two devices
connected in the configuration exchange data frames with each other to synchronize their
operating statuses (one device is master and the other slave). If there are no problems, only
the link from the master to the other network segment is active. If this link fails (for example
due to a link-down or a device failure), the slave activates its link as long as the problem
persists. Reconfiguration takes place within 0.3 s.
Note
If SCALANCE X408
-2 are used exclusively for redundant coupling of the gigabit rings, the
coupling links can also be designed with a gigabit transmission rate.

Properties, functionality and features of SCALANCE X-400
This chapter explains special properties, features, and options available to you with
IE Switches X-400.
The basic device always consists of the frame, the power supply and a CPU module. The
basic device of the SCALANCE X414-3E has additional digital signal inputs.
IE Switches X-400 provide a modular structure for the required ports. The modularity
simplifies setup and subsequent expansion of complex network topologies to meet current
needs.
● Gigabit technology
The basic device has ports with a transmission rate of 1 Gbps for electrical cables
(twisted pair) or by adding gigabit media modules for fiber-optic cables (FO).
● With IE-Switches X-400, it is possible to split the ring ports on two different slots. If one of
the media modules fails, operation can be maintained as a linear bus structure. A
defective module can be replaced during operation.
● The basic device has a signaling contact for local operator control.
● There is a serial interface available for local diagnostics and local configuration.
● C-PLUG
When replacing a device, the C-PLUG can be removed and inserted in the new device
so that the configuration can be retained.

3.3.2.1
10Base-T / 100Base-TX
Transmission rate
The transmission rate of the electrical ports is 10 Mbps or as Fast Ethernet ports 100 Mbps.
Transmission mode
The transmission mode for 10Base-T / 100Base-TX is specified in the IEEE 802.3i / IEEE
802.3u standards of the Institute of Electrical and Electronic Engineers.
Autonegotiation (automatic detection of the best transmission modes) is default. The order in
which they are selected is:
● 100Base-TX full duplex
● 100Base-TX half duplex
● 10Base-T full duplex
● 10Base-T half duplex
Two communication modes are possible:
● Half duplex
Two-way alternate transmission mode - it is only possible to either send or receive over
the interfaces at any one time.
● Full duplex mode
Two-way simultaneous - both communication partners can send and receive at the same
time.
Connections to other switches can use half or full duplex; connections to hubs are possible
only in half duplex mode.
Transmission medium
Data transmission at 10 Mbps and at 100 Mbps is over two wire pairs (pin 1, 2, 3, 6) of the
twisted pair cable. For 10 Mbps, at least a category 3 (Cat 3) and for 100 Mbps, at least a
four-wire (2x2) category 5 (Cat 5) cable is necessary.
Transmission range
The maximum transmission range (segment length) is 100 m.
Connectors
The connectors used are 8-pin RJ-45 jacks with securing collars. The securing collar in
conjunction with the cover ensures a flush fit and the locking mechanism with the
PROFINET-compliant male connectors IE FC RJ-45 Plug 180 and IE FC_RJ-45 Plug 145
provides a rugged node attachment suitable for an industrial environment that provides strain
and bending relief for the RJ-45 jack.

Transmission rate
The transmission rate of the optical Fast Ethernet ports is 100 Mbps.
Transmission mode
Transmission with 100Base-FX is defined in the IEEE 802.3u standard and is specified as
100 Mbps transmission rate and full duplex.
Transmission medium
Data transmission is over multimode or single mode fiber-optic cable (FOC).
Two FOC types can be used:
● Multimode FOC
The core diameter is 50 µm; the light source is an LED. Many modes are used for signal
transmission. The propagation times of the light pulses (dispersion) restrict the maximum
range considerably.
● Single mode FOC
The core diameter is 9 or 10 µm; the light source is a laser diode. To transmit a signal,
only one mode is used greatly reducing dispersion. As a result, the maximum range of
single mode FOC is greater than that of multimode FOC.
Regardless of the type used, the outer diameter of the FOC is 125 µm.
Transmission range
The maximum transmission range (segment length) depends on the module selected and
the FOC. The range is as follows:
● 100Base-FX module and multimode FOC: 3 km
● 100Base-FX-LD module and single mode FOC: 26 km
● 100Base-FX-LH/ LH+ module and single mode FOC: 70 km
Connectors
The connectors used are BFOC sockets or SC duplex sockets with the 100BaseFX LH/ LH+
module.

C-PLUG (configuration plug)
Application
The C-PLUG is an exchangeable medium for storage of the configuration data of the
modular switch and ships with the product. This means that the configuration data remains
available if the basic device is replaced.
Note
The C
-PLUG must only be removed or inserted when the power supply to the device is
turned off.
How it works
Power is supplied by the end device. The C-PLUG retains all data permanently when the
power is turned off.
If an empty C-PLUG (factory settings or deleted with the Clean function) is inserted, all the
configuration data of the IE Switch X-400 is saved to it automatically when the device starts
up. Changes to the configuration during operation without operator intervention are saved on
the C-PLUG if this is in the "ACCEPTED" status.
Figure 3-33 C-PLUG
Description
3.4 Description of the product
SCALANCE X-400
Operating Instructions, 10/2013, C79000-G8976-C186-11 73
A device with an "ACCEPTED" C-PLUG inserted uses the configuration data of the C-PLUG
automatically when it starts up. Acceptance is possible only when the data was written by a
compatible device type.
This allows a basic device to be replaced quickly and simply. The C-PLUG is taken from the
failed component and inserted in the replacement. The first time it is started up, the
replacement device has the same configuration as the failed device except for the MAC
address set by the vendor.
Note
If an IE
Switch X-400 is replaced, the configuration with media modules and when using a
SCALANCE X414
-3E also the settings of the DIL switches on the CPU module and the
optional configuration of extender modules must be adopted.
Diagnostics
Inserting a C-PLUG that does not contain the configuration of a compatible device type,
accidentally removing the C-PLUG or general malfunctions of the C-PLUG are signaled by
the diagnostics mechanisms of the device (LEDs, WEB-based management, SNMP, and
CLI).
Startup behavior

In cases 1 and 2, the configuration data on the CPU module and the C-PLUG is identical. In
cases 3 and 5 the configuration data is different and can be synchronized manually. In case
6, you can attempt to reformat the C-PLUG with the clean function. If problems persist,
replace the C-PLUG.
Note
When using a SCALANCE X414
-3E, in case 4 (replacing the switch), the DIL switch settings
of the C
-PLUG and not the physical switch settings are adopted. A deviation is signaled by
the diagnostic options.

NOTICE
If IE Switches X-400 are supplied over long 24 V power supply lines or networks, measures
are necessary to prevent interference by strong electromagnetic pulses on the supply lines.
These can result, for example, due to lightning or switching of large inductive loads.
One of the tests used to attest the immunity of devices of the IE Switches X-400 to
electromagnetic interference is the "surge immunity test" according to EN61000-4-5. This
test requires overvoltage protection for the power supply lines. A suitable device is, for
example, the Dehn Blitzductor VT AD 24 V type no. 918 402 or comparable protective
element.

The FastConnect cabling system
With the IE FC RJ-45 Plug and the FastConnect cables (FC), you can achieve a segment
length up to 100 m without patching. In this case, the IE FC standard cable 2x2 is connected
directly to the SCALANCE X414-3E and other components on the network.
Two FastConnect cable types are available, the eight-wire IE FC standard cable 4x2 and the
four-wire IE FC standard cable 2x2.
The diameter of the IE FC standard cable 4x2 does not allow connection to an RJ-45 plug so
that only the IE FC standard cable 2x2 as a four-wire cable is suitable for RJ-45 plugs. This
means that the maximum transmission rate is 100 Mbps.
The flexible eight-wire patch cable (TP cord) for gigabit transmission allows a maximum
cable length of 10 m.

Removing the FC cable from IE Switches X-400
Under some circumstances, a screwdriver is necessary to remove the twisted pair cables
with RJ-45 plugs because it may not be possible to reach the connector with your hand due
to neighboring media modules, covers, or the dummy cover.
If this is the situation, do the following:
1. Press the catch on the RJ-45 plug to the left with a small screwdriver.
2. Remove the cable.

DIL switches of the SCALANCE X414-3E
Meaning of the DIL switches
The RM switch allows you to configure the SCALANCE X414-3E as a redundancy manager
in a ring with redundancy manager.
Note
Only the SCALANCE X414-3E basic device has DIL switches.
Ring redundancy can be configured with these DIL switches. If both switches R1 and R2 are
set to ON, ring redundancy can only be configured by software (CLI, WBM). These settings
can only be made in the software
for the SCALANCE X408-2 basic device. On the
SCALANCE
X408-2, the RM can also be enabled / disabled with the SET/SELECT button.
For more detailed information, refer to the configuration manual "SCALANCE

SELECT / SET button
Function
The SELECT / SET button is used to switch over the display modes (DMode) and to make
other settings. After turning on the IE Switch X-400, it is in DMode A.
The button has the following functions:
● Changing the display modes
By pressing the button briefly, you change from one display mode to the next. The
selected mode or current status is displayed by the LEDs (D1, D2).
● Resetting to the factory defaults
It is possible to restore some of the factory defaults in DMode A. by pressing the button
for 12 seconds. You can cancel the reset procedure by releasing the button before the 12
seconds have elapsed. All previously made settings are overwritten by the factory
defaults.
● Defining the fault mask and the LED displays
It is possible to set the fault mask in DMode A and DMode D. This allows you to specify
the mask for signaling faults by defining an individual "good status" for the connected
ports and the power supplies. In this case, you press the button for 5 seconds in DMode
A or DMode D. After 3 seconds, the two LEDs (D1 and D2) start to flash. You can cancel
the procedure by releasing the button before the 5 seconds have elapsed. If, however,
you press the button for a further 2 seconds, the current states of all ports and the states
of the power supplies L1 and L2 are included in the fault mask. The previous fault mask is
then overwritten.
● Activating/deactivating the redundancy manager (only with the SCALANCE X408-2 basic
device)
It is only possible to activate/deactivate the RM in DMode B by pressing the button for 5
seconds. After 3 seconds, the two LEDs (D1 and D2) start to flash. If you release the
button before the 5 seconds have elapsed, the action is aborted. After 5 seconds the
redundancy manager is activated/deactivated. If the redundancy manager as well as ring
redundancy were deactivated, ring redundancy is also activated at the same time. If you
deactivate, only the redundancy manager is deactivated.

This can be used, for example, when assigning addresses to make sure that the correct
node receives the address. All port LEDs of the addressed node flash green at 2 Hz.
With the PST Tool V3.0, you can trigger this function with "Module \ Ring".
