Introduction
Introduction
1
The switching technology of the Industrial Ethernet OSM Version 2/ESM
(Optical/Electrical Switching Module) allows the structuring of Ethernet networks
with large spans and large numbers of nodes. It simplifies network configuration
and network expansions. The OSM Version 2/ESM are simply called OSM/ESM in
the rest of this manual.
The OSMs have both electrical ports and additional FO ports via which several of
these devices can be interconnected to form an optical bus or ring configuration.
ESMs only have electrical ports.
DTEs, other OSMs/ESMs or complete network segments operating at 10 or 100
Mbps can be connected to the electrical autonegotiation (autosensing) ports of the
OSM/ESM. The transmission rate is detected automatically.
To increase availability, ring configurations can be created with OSMs or ESMs. To
do this, OSMs or ESMs are first connected together to form a bus using their ring
ports. The ends of the bus are closed to form a ring by an OSM or ESM operating
in the Redundancy Manager mode (RM mode).
The OSM or ESM operating in the RM mode monitors the attached bus and allows
a connection through it if it detects an interruption on the attached bus; in other
words, it reestablishes a function bus. Reconfiguration is completed within 0.3s. An
OSM/ESM is switched over to the RM mode using a DIP switch on the device.
The redundant standby coupling allows the redundant coupling of OSM/ESM or
OLM rings. To do this, two OSM/ESMs (one operating in standby mode) are
connected via their standby-sync ports.
With the ITP variants of the OSM/ESM, the DTEs are connected using sub-D
female connectors. This connector technology allows direct links over distances up
to 100 m. With the TP variants, the DTEs are connected using RJ-45 jacks.
The Version 2 OSMs are compatible with the previous OSM variants (6GK 11050AA00) and ORM (6GK1105-1AA00) and can, for example, be mixed with these in
an optical ring.
This manual describes the functions of the OSM/ESM available without using
network management. The OSM/ESM Network Management user manual /1/
describes the additional options available if you use network management. You will
find this manual on the CD accompanying every OSM/ESM or you can download
the manual from the Web in Siemens Customer Support under entry number

ESM TP40
Possible Attachments
The ESM TP40 allows attachment of up to 4 DTEs or network segments with TP
connectors (RJ-45 jack). By coupling further ESMs via ports 3 and 4 it is possible
to create bus and ring structures.
The ESM TP40 also has four digital inputs. The states of the inputs are available
in a management information base (MIB) and can be read using an SNMP get
request. Depending on the configuration of the device, changes at these inputs
can also trigger the sending of E-mails, SNMP traps and/or entries in the log of the
ESM. The use of these functions is described in the OSM/ESM Network
Management User Manual /1/.

This chapter discusses the general functions of the OSM/ESM, in particular the
properties of the switching technology.
Increased Network Performance
By filtering the data traffic based on the Ethernet (MAC) address of the DTEs,
local data traffic remains local, only data intended for nodes in another network
segment are passed on by the OSM or ESM. This reduces the data traffic in the
network segments and lowers the network load in the network segments.
Simple Network Configuration and Network Expansion
OSMs and ESMs store the data received at the ports and the direct it to the
destination address. The restriction of the network span resulting from collision
detection (CSMA/CD) ends at the OSM/ESM port. With multimode graded-index
fibers, a total network span of up to 150 km and more can be achieved without
problems. With the OSM ITP62-LD, the monomode fibers allow a network span of
up to 1300 km.
Limitation of Errors to the Network Segment Affected
OSMs and ESMs only pass on valid data. Invalid packets are discarded so that
bad packets within a network segment have no effect on any other segment
attached to the OSM/ESM.
Learning Addresses
By evaluating the source addresses in the data packets, OSMs/ESMs
automatically learn the addresses of the DTEs attached via a particular port. If an
OSM/ESM receives a data packet, it directs this packet only to the port via which
the appropriate DTE can be obtained.
An OSM/ESM can learn up to 7000 addresses.
Industrial Ethernet OSM/ESM
C79000-Z8976-C068-10

Functions
Deleting Addresses
An OSM/ESM monitors the age of the addresses it has learnt - address entries that
exceed a certain age (aging time, default setting on the OSM/ESM 40 seconds) are
deleted again by the OSM/ESM. If a packet with a source address matching the
address entry is received before the aging time elapses, the address entry is
retained and the age of the address is set to 0 again. When the OSM/ESM is
restarted, the address entries are also deleted. If a packet is received by an
OSM/ESM for which there is no address entry, the OSM/ESM distributes it to all
ports.
Setting the Transmission Rate, Autonegotiation
The electrical ports of the OSM/ESM are set to autonegotiation mode as default
(autosensing).
They automatically detect the transmission rate (10 or 100 Mbps) at which the
attached device or attached network segment operates and set themselves to this
rate. If the partner device also supports the autonegotiation mode, the devices
further negotiate whether they will exchange data with each other in the half duplex
or full duplex mode.
As a result of the automatic adaptation to the transmission rate of the attached
DTEs, existing network segments operating at 10 or 100 Mbps can be
interconnected simply using OSMs/ESMs.
Note
If the partner device connected to a port of an OSM/ESM does not support the
autonegotiation mode (for example OSM Version 1), the port of the partner device
must be set to half duplex mode or the port properties of the OSM/ESM must be
configured.
Packets with the VLAN Priority Tag
OSMs/ESMs support frames with VLAN tags according to IEEE 802.1Q.
VLAN tags are additional information entered in the frame header. This additional
information includes a priority field according to IEEE 802.1D. This field can have
values from 0 through 7 and allows frames to be assigned a priority from 0 (lowest
priority) through 7 (highest priority).
Frames with priority 0 through 3 are processed with low priority in the OSMs/ESMs
and frames with priority 4 through 7 are processed with high priority.
Frames with a non-learned unicast destination address are an exception. These
are always handled with low priority.

Notice
Frames with a priority higher than 3 can have a negative effect on the redundancy
functions of OSMs/ESMs so that the reconfiguration time of maximum 0.3 seconds
can no longer be guaranteed and higher failover times result.

Bus Structure
With OSMs or ESMs, bus structures can be implemented . The cascading depth
and total span of a network are limited only by the monitoring times of the
communication connections. These times must always be set higher than the
signal delay of the transmission path.

Redundant Ring Structure
With the aid of an OSM functioning as the redundancy manager (RM), both ends
of an optical bus made up of OSMs can be closed to form a redundant optical ring.
The OSMs are connected together using ports 7 and 8.
The RM monitors the OSM bus connected to it, closes the bus if it detects and
interruption and therefore reestablishes a functioning bus configuration. A
maximum of 50 OSMs are permitted in an optical ring. This allows reconfiguration
time of less than 0.3 s to be achieved. The RM mode is activated on the OSM
using a DIP switch (Section 4.2.4.1).

A redundant electrical ring can be established using ESMs in the same way. To
achieve this the ESMs must be connected together using ports 7 and 8. One
device must be switched to the redundancy manager mode. With ESMs and a
maximum of 50 devices in the ring, a reconfiguration time of less than 0.3 s can
also be achieved.

Notes

•
The reconfiguration time of less than 0.3 s can only be achieved when no
components other than OSMs and ESMs (for example switches) are used in
the redundant ring.
•
In a ring, one device and one device only must operate in the redundancy
manager mode.
•
DTEs or complete network segments can be connected to ports 1 – 6
(OSM/ESM with 8 ports) or ports 1 and 2 (OSM/ESM with 4 ports) of an
OSM/ESM operating in the RM mode.

3.3
Redundant Coupling of Network Segments
The standby-sync port of an OSM/ESM with 8 ports allows the connection of two
Industrial Ethernet OSMs or ESMs with one operating as standby master (DIP
switch "Stby off") and the other as standby slave (DIP switch "Stby on"). With this
mode, pairs of OSMs/ESMs can be used for redundant coupling of OSM/ESM or
OLM rings.
With network management, the OSM/ESM can also be configured so that several
rings or networks can be interconnected at the same time with two OSMs/ESMs
(see OSM/ESM Network Management, User Manual /1/).

Network Topologies with OSM/ESM
The connection between two network segments is on two separate paths. Two of
the OSMs/ESMs in a ring are connected together via a connecting cable (ITP-XP
standard cable 9/9 with a maximum length of 40 m) and inform each other of their
operating states. One of these OSMs/ESMs is assigned the redundant function
using the DIP switch setting "Stby on" (standby slave). The other OSM takes over
the function of the standby master (DIP switch setting "Stby off").
Immediately following the failure of the main transmission path, the standby slave
enables the redundant path. If the main path is OK again, the standby master
informs the standby slave. The main path is enabled and the redundant path
disabled again. The reconfiguration time of the redundant ring coupling is less than
0.3 s.
Port Assignment in the Standby Mode
On the standby master and standby slave only port 1 (standby port) can be used
for the coupling to the neighboring ring. Ports 2 - 6 can be used just as normal
OSM ports.
With network management, it is also possible to configure ports other than port 1
as standby ports (see also OSM/ESM Network Management User Manual /1/).
Simultaneous Standby and Redundancy Manager Operation
A standby master or standby slave can adopt the function of a redundancy
manager at the same time.
Replacing the Standby Master During Operation
When replacing a standby master during operation, the following order is
necessary to prevent an interruption on the network:
1. Remove the terminal block for the power supply on the standby master
2. Remove the signal lines and the standby connecting cable from the standby
master.
3. Connect the signal lines to the standby connecting cable on the replacement
device.
4. Plug in the terminal block for the power supply on the replacement device.
When replacing a standby slave, no special measures are necessary. You must
simply make sure that the standby master is active.

Compatibility
Version 2 OSMs can be operated at the same time in the ring with the OSM (6GK
1105-0AA00) and ORM (6GK 1105-1AA00) here called OSM/ORM Version 1.
Make sure that only one device can adopt the redundancy manager function in the
ring; in other words, only one ORM or only one OSM Version 2 operating in the RM
mode.

Coupling Network Segments
A network segment can be connected to each of the ports of an OSM/ESM.
The Ethernet Planning Rules:
• Sum of the delay equivalents and cable lengths in the worst-case path shorter
than 4520 m
• Sum of the variability values in the worst-case path less than 50 bit times
need only be maintained as previously in each individual segment (see also
"SIMATIC NET Industrial Twisted Pair and Fiber Optic Networks" manual).
The coupling of network segments via OSM has further advantages:
• The collision domain ends at the OSM ports and the network segments
attached to them, the permitted total network span increases.
• Only valid data packets are passed on via OSM ports. Network segments with
problems cannot influence other network segments.
• Data packets are only passed on to the ports to which the DTE with the
destination address is connected. The available transmission capacity
increases since the local data traffic of a network segment no longer puts load
on another network segment.

ITP/TP Ports
This chapter describes the properties of ITP and the TP ports.
4.1.1
ITP Ports
In the ITP variant of the OSM/ESM, the DTEs are attached via sub-D female
connectors. The casings of the connectors are electrically connected to the casing
of the OSM. A screw locking mechanism holds the connectors firmly in place.

Crossover).

C79000-Z8976-C068-10
Interfaces, Displays and Operator Controls
4.1.3
Properties of the TP/ITP Ports
Link Control
OSMs/ESMs monitor the connected TP/ITP cable segments for short-circuits or
wire breaks using regular link test pulses complying with the 100BASE-TX
standard. OSMs/ESMs do not send data to a segment from which they are not
receiving link test pulses. An unused interface is taken to be a wire break since the
device without power cannot send link test pulses.
Auto Polarity Exchange
If the receive cable pair is incorrectly connected (RD+ and RD- swapped over), the
polarity is automatically reversed.
Autonegotiation Mode
The TP/ITP ports of OSM/ESM are set to the autonegotiation mode.
They automatically detect the transmission rate (10 or 100 Mbps) at which the
attached device or attached network segment operates and set themselves to this
rate. If the partner device also supports the autonegotiation mode, the devices
further negotiate whether they will exchange data with each other in the half duplex
or full duplex mode.
Note
If the partner device connected to a port of an OSM/ESM does not support the
autonegotiation mode (for example OSM Version 1), the port of the partner device
must be set to half duplex mode.
Autocrossover Function
OSMs/ESMs with digital inputs are capable of switching over their TP/ITP ports
automatically between MDI and MDI-X pinning; in other words, they can cross over
the send and receive data internally, when necessary.
This means that regardless of the port type of the device you are connecting and
the type of Ethernet cable, a connection can be established. Crossover cables are
not necessary.
Industrial Ethernet OSM/ESM
C79000-Z8976-C068-10
45
Interfaces, Displays and Operator Controls
Note
The autocrossover function of a TP/ITP port of the OSM/ESM is active only when it
is set to the autonegotiation mode.
If this is not the case, it may be necessary to replace a straight-through cable with
a crossover cable.
Please remember that even when using straight-through cables, an illegal loop can
occur in the Ethernet network, caused, for example, by connecting two ports on an
OSM/ESM. Such a loop can lead to network overload and network failure.

FO Ports
The FO ports have BFOC/2.5(ST) female connectors. They monitor the connected
cable for wire breaks complying with the IEEE 802.3 100 Base-FX standard. A
break on the FO cable is always signaled by the port status display of the two
attached OSMs (status LED of the port goes off).
Note
The FO ports operate at the fixed transmission rate of 100 Mbps. And optical link,
for example, to OLM (10 Mbps) is not possible.

Warning
Industrial Ethernet OSMs/ESMs are designed for operation with safety extralow voltage. This means that only safety extra-low voltages (SELV)
complying with IEC950/EN60950/ VDE0805 can be connected to the power
supply terminals and the signaling contact.
The power supply unit to supply the OSM/ESM must comply with NEC Class
2 (voltage range 18 - 32 V, current requirement 1 A)
The signaling contact can carry a load of maximum 100 mA (safety extra-low
voltage (SELV), DC 24V).
Exceptions:
•
Supply by PELV (corresponding to VDE 0100-410) is also permitted if the
generated nominal voltage does not exceed the voltage limits 25 V a.c. or
60 V d.c.
•
Supply by a SELV current source (corresponding to IEC 60950) or PELV
current source (corresponding to VDE 0100-410) power limitation is also
permitted as long as suitable fire protection measures are taken as
follows:
- Installation in a cubicle
- Installation in a suitable enclosure
- Installation in a suitably equipped room.
Industrial Ethernet OSM/ESM

Power Supply
The power supply can be connected redundantly. Both inputs are isolated. There is
no load distribution. With redundant power supply, the power supply unit with the
higher output voltage supplies the OSM/ESM alone.
Signaling Contact
The following is signaled via a floating signaling contact (relay contact) when
contact is broken:
• The failure of a monitored power supply. Which power supply is monitored is
specified in the fault mask (see Section 4.2.3).
• The incorrect link status of a monitored port (in other words, the port is not
correctly attached or there are no link test pulses coming from the partner
device). The ports to be monitored are selected using the fault mask.
• When at least one port is segmented.
• If the DIP switch setting was changed during operation.
(Inconsistency between the switch setting and the actual operating state
because the switch setting is adopted only after a restart)
In the RM Mode (additional)
• The incorrect link status of port 7 or port 8 of the OSM ITP62, OSM ITP53, ESM

Digital Inputs
In the case of the OSMs/ESMs with digital inputs, the states of these inputs are
available in a management information base (MIB) and can be read with an SNMP
get request. Depending on the configuration of the device, changes at these inputs
can also trigger the sending of E-mails, SNMP traps and/or entries in the log of the
OSM/ESM. The use of these functions is described in the OSM/ESM Network
Management User Manual /1/.
The digital inputs are attached using six-pin plug-in terminal blocks with screw
locking mechanisms.

RM – Redundancy Manager (green LED)
Status
Lit
Meaning
The OSM/ESM is operating in the redundancy manager mode.
The ring is operating free of errors in other words the
redundancy manager does not allow traffic through but
monitors the ring.
Note: One OSM must operate in the redundancy manager
mode (and one only) in each OSM/ESM ring.
Not lit
The OSM/ESM is not in the redundancy manager mode.
Flashes
The OSM/ESM is in the redundancy manager mode and has
detected a break on the ring. The OSM/ESM makes the
connection between its two ring ports so that a functional bus
configuration is reestablished.

"Select/Set" Button
The "Select/Set" button on the front panel of the OSM/ESM has the following
functions:
• Pressing the button briefly moves on the display of the port LEDs (display
mode). The current display mode is indicated by the display mode LEDs.
• If the display is in the port status (all display mode LEDs off) and if the button is
pressed for three seconds, the display mode LEDs begin to flash. If you then
continue to press the button for a further two seconds, the OSM/ESM is reset.
When it is reset, all the settings of the OSM/ESM are set to their defaults (as set in
the factory). This allows you to cancel settings made, for example, with Web-Based
Management (WBM) (see also OSM/ESM Network Management, User Manual).
• If the display is in the fault mask status and you press the button for two
seconds, the display LEDs start to flash. If you then press the button for a
further two seconds, the current status of the ports and the supply voltages are
entered in the fault mask. This means, if, for example, the ports 1, 5, 6 had a
valid connection (in other words the port status displays of these ports are lit
green or yellow) and if power supply 1 was active at the point when the values
were entered in the fault mask, ports 1, 5, 6 and power supply 1 will then be
monitored.
Note
If the "Select/Set" button is pressed while the device is starting up (takes
approximately 20 seconds) after turning on the OSM/ESM, the OSM/ESM changes
to the load firmware status (all display mode LEDs flash simultaneously). This
status is exited by pressing the button again. For further information on loading the
firmware, refer to Chapter 6.

Glossary
Autocrossover
Mechanism with which a TP port is automatically switched over
between MDI and MDI-X pinning to establish a connection regardless
of the port pinning of the device being connected. This makes the use
of crossover cables unnecessary.
The autocrossover function is available only when the port is set to
autonegotiation mode.
Autonegotiation
Procedure standardized by IEEE 802.3 in which the transmission
parameters (for example 10/100 Mbps, full/half duplex) are negotiated
automatically between the devices.
Auto Polarity
Exchange
Procedure in which the module automatically detects incorrect
attachment of a cable to the electrical OSM/ESM port (RD+ and RDswapped over). The OSM then reverses the polarity automatically.
Autosensing
See Autonegotiation
Backbone
In conjunction with the OSM/ESM, this means a bus or ring structure
made up of interconnected OSM or ESM modules that form the
backbone of an industrial LAN.
Display Mode
The display mode LEDs indicate the display mode in which the port
and power LEDs and the attached input signals (OSMs/ESMs with
digital inputs only) of the OSM/ESM are currently working. The display
mode can be changed with the button on the front panel of the
OSM/ESM.
ESM
Electrical Switching Module. SIMATIC NET Ethernet switch with
electrical ports
Fault Mask
The fault mask specifies which ports (ports 1 - 8) and power supply
terminals (line 1/2) are monitored by the signaling contact. The fault
mask can be set again with the button on the front panel of the
OSM/ESM.
Filtering
OSMs/ESMs learn the addresses of the devices that can be accessed
via a port. They redirect the packets intended for this device only via
this port.
ITP Port
Port with Industrial Twisted Pair (ITP) connector (sub D 9-pin female)

Glossary
Latency
The latency specifies the taken for packets to pass through the
OSM/ESM. It is assumed that a received packet can be sent on
immediately. The latency does not include the time necessary for the
OSM/ESM to receive a packet.
Link Control
OSMs/ESMs monitor the connected TP/ITP cable segments for shortcircuits or wire breaks using regular link test pulses complying with the
100BASE-TX standard. OSMs/ESMs do not send data to a segment
from which they are not receiving link test pulses. An unused interface
is taken to be a wire break since the device without power cannot send
link test pulses.
MDI-X
Medium Dependent Interface Crossover
RJ-45 jack with pinning of a network component
OSM
Optical Switching Module. SIMATIC NET Ethernet switch with optical
and electrical ports
Reconfiguration Time Time required by the OSM/ESM operating in the redundancy manager
(RM) or standby mode to reestablish a functioning configuration if a
device fails or the cable is interrupted.
Redundancy Manager Mode of an OSM or ESM for forming a redundant ring structure. The
(RM)
RM monitors the OSM or ESM bus connected to it, closes the bus if it
detects and interruption. This reestablishes a functioning bus
configuration.
One and only one device can operate in the RM mode in every OSM or
ESM ring.
Signaling Contact
Floating relay contact via which the error states detected by the
OSM/ESM can be signaled.
Standby-sync port
Port of an OSM/ESM via which two OSMs or ESMs are interconnected
in a redundant ring link allowing them to inform each other of their
operating states (not available with the OSM TP22 and ESM TP40).
Store and forward
In this switching method used on the OSM/ESM, the complete packet
is read in before it is passed on by the switch. A packet is only passed
on if it is error-free.
TP Port
Port with a TP connector (RJ-45 jack)
