What Are Distributed I/O Devices?
Distributed I/O Device – Area of Application
When a system is set up, the inputs and outputs to and from the process are often
located centrally in the programmable controller.
If there are inputs and outputs at considerable distances from the programmable
controller, there may be long runs of cabling which are not easy to follow, and
electromagnetic interference may impair reliability.
Distributed I/O devices are the ideal solution for such systems:
The controller CPU is located centrally.
The I/O devices (inputs and outputs) operate locally on a distributed basis.
The high-performance PROFIBUS-DP ensures with its high baud rates that the
controller CPU and I/O devices communicate smoothly.

Product Overview
What Is PROFIBUS-DP?
PROFIBUS-DP is an open bus system based on the
IEC 61784-1:2002 Ed1 CP 3/1 standard with the ”DP” transmission protocol (DP
being the German abbreviation for distributed I/O).
Physically, PROFIBUS-DP is either an electrical network based on a shielded
two-wire line or an optical network based on a fiber-optic cable.
The ”DP” transmission protocol allows a rapid, cyclic exchange of data between
the controller CPU and the distributed I/O devices.
What Are DP Masters and DP Slaves?
The DP master links the controller CPU with the distributed I/O devices. The DP
master exchanges data by means of PROFIBUS-DP with the distributed I/O
devices and monitors PROFIBUS-DP.
The distributed I/O devices (= DP slaves) prepare the data of the sensors and
actuators so that it can be transferred via PROFIBUS-DP to the controller CPU.
Which Devices Can be Connected to PROFIBUS-DP?
A wide range of devices can be connected to the PROFIBUS-DP bus system as
DP masters or DP slaves, provided their behavior conforms to
IEC 61784-1:2002 Ed1 CP 3/1. The devices that can be used include the following:

Structure of a PROFIBUS-DP Network
The figure below shows you a typical PROFIBUS-DP network configuration. The
DP masters are integrated in the relevant device – for example, the S7-400 has a
PROFIBUS-DP interface, and the IM 308-C master interface module is inserted in
the S5-115U. The DP slaves are the distributed I/O devices connected to the DP
masters via PROFIBUS-DP.

EWA-4NEB780600602-06
Product Overview
”SIMATIC S7-DP Slave”
The ET 200M distributed I/O system is part of the SIMATIC S7 programmable
controller.
This means STEP 7 supports you when you configure, program and assign
parameters to the ET 200M in the DP master system and during commissioning
and diagnostics. Certain services and functions of the IM 153-2 (for example
parameterizable FM or redundancy) can only be used fully in SIMATIC S7/PCS 7.
If you use the ET 200M with a DP standard master (e.g. S5-95U), you will also be
supported by the configuration tool in the device master file, but you must pay
attention to the technical specifications (typical application specifications) of the DP
master (possible parameter assignment frame length and diagnostic frame length
etc.).
The PROFIBUS standard IEC 61784-1:2002 Ed1 CP 3/1 also includes DPV1
operation. You can only use this operating mode if you integrate the device master
file revision w 3.
The device master file revision 2 is still available to ensure compatibility with
previous versions of the IM 153-x interface module.

Prerequisites
You have set up an S7 station consisting of a power supply module and a DP
master (e.g. CPU 315-2 DP). In this sample configuration a CPU 315-2 DP is
used as the DP master. It is, of course, possible to use a different DP master
(IEC 61784-1:2002 Ed1 CP 3/1 standard).
The latest STEP 7 version is fully installed on your programming device (PG).
The functionality of the configuration may be restricted if older STEP 7 versions
are used. You should be familiar with STEP 7.
Installation
1. Mount the rail on a firm base so that there is at least 40 mm clearance above
and below the rail.
2. Starting from the left side, mount the individual modules on the rail (plug in the
bus connectors (not for PS 307 and the last module) – engage – swing in –
screw down). Observe the following sequence:
– Power supply PS 307
– Interface module IM 153-2
– DI module SM 321
– DO module SM 322
3. Set PROFIBUS address 3 at the interface module IM 153-2.

Wiring
Rail
1. Connect the rail to the protective conductor. An M6 screw is provided for this
purpose on the rail.
Minimum cross-section from the conductor to the protective conductor: 10 mm2.
Warning:
You could touch live wires if the power supply module PS 307 is switched on or the
supply cable of the power supply is connected to the mains supply.
Make sure the ET 200M is de-energized before doing any wiring.
Power Supply and IM 153-2
1. Open the front doors of the PS and IM.
2. Undo the strain-relief assembly on the PS 307.
3. Strip the power supply cable. If necessary, attach wire end ferrules (in the case
of multi-conductor cables). Then connect to the PS 307 (see Figure 2-3).
4. Screw the strain-relief assembly tight.
5. Insert the jumper into the PS 307 and IM 153-2, and screw it tight (see
Figure 2-3).
6. Check that the switch for selecting the mains voltage on the PS 307 is set to
your mains voltage.
The power supply module is factory-set to a mains voltage of 230 V AC. You
can change the setting in the following way: remove the protective cover using
a screwdriver, set the switch to the available mains voltage and reattach the
protective cover.
7. Connect the PROFIBUS-DP cable between the DP master (2nd DP interface)
and the IM 153-2. The terminating resistors in the connectors must be switched
on.
Front Connectors of the DI and DO
1. Open the front doors of the DI and DO.
2. Move the front connector to the wiring position:
To do so, push a front connector into each DI and DO until it engages. The front
connector still protrudes from the module in this position. In the wiring position a
wired front connector has no contact with the module.
3. Strip 6 mm of insulation off the ends of the wires you want to insert into the
front connector and then attach appropriate wire end ferrules to the wire ends.

Terminal 20: M of PS;
Terminals 3 and 20: indicator lamp (see Figure 2-3)
6. Guide the wires down and out of the front connectors.
7. Press the release button of the front connector on the top of the module and
simultaneously push the front connector into the module until the release button
returns to its original position.
8. Close the front doors of PS, DI and DO.

Sample Configuration with an IM 153-2 and FM
Figure 3-3 shows an example of an ET 200M with an IM 153-2 and two SMs and
two FMs of the S7-300 I/O modules. The S7 DP master and PG/OP can
communicate directly with the parameterizable FM via the IM 153-2 (the gray line
indicates the communication path). Parameterizable FMs are, for example, the
FM 353/354/355.
The following S7 functions are supported by the IM 153-2:
FM parameter assignment by means of the DP master CPU
Commissioning and diagnostics of the FM by means of a PG/PC
Operation and monitoring of the FM by means of an OP.

Time Stamping with the IM153-2
Time stamping with IM 153-2 is possible
in customer applications which use FB 62 (FB TIMESTMP)
(see online help for STEP 7)
with the PCS 7 system solution with accuracy of 10 ms
A detailed description of time stamping with 10 ms accuracy and time
synchronization can be found in the PCS 7 function manual ”10 ms Time
Stamping”.
Operating Principle
You set parameters to determine which user data of the IM 153-2 is monitored. For
time stamping it is digital inputs which are monitored for signal changes.
A changed input signal is given a time stamp and stored in a buffer (data record). If
time-stamped signals exist or a data record is full, a process interrupt for the DP
master is generated. The buffer is evaluated with ”Read Data Record”. Special
messages are generated in the case of results which influence time stamping
(interrupted communication with DP master, message failure from time master, ...).

3.4.1
Time Stamping with 10 ms Accuracy
The time stamping of signal changes is supported throughout the PCS 7 system by
all the hardware and software components: from the IM 153-2 via an S7-400 to the
OS.
Prerequisite
The synchronization interval must be set to 10 seconds.
Principle
By carrying out configuration in STEP 7 you can monitor digital inputs for signal
changes in a system. The ”coming/going signal” (rising or falling edge) is
monitored. The IM 153-2 records these altered input signals with the current time
(time stamp) and stores them as message lists. A message list is a record with a
maximum of 20 messages about time-stamped signal changes. The IM 153-2 can
store up to 15 records.
After a certain time has elapsed and if there are any messages or if a record is full,
the IM 153-2 triggers a process interrupt in the DP master (S7-400). The CPU then
reads the record and forwards the message lists to WinCC in an OS using the FB
90 “IM_DRV” driver block (included in PCS 7 software package).

In the Redundant System
The IM 153-2 also supports the time stamp function in the redundant S7-400H
system.
Time Stamping Signal Changes in a S7-400H
The two IM 153-2 modules store the messages of the time-stamped signals. This
makes it possible, after a switchover operation from the active to passive IM 153-2,
for the “new” active IM 153-2 to forward the current messages to WinCC.
Note: During switchover between the two IM 153-2, signal changes are not time
stamped. You can see in WinCC when time stamping hasn’t taken place.
You can find further information on time stamping in redundant systems in the
PCS 7 documentation.

on S5 DP masters (e.g. S5-115H)
with software redundancy
in accordance with the relevant standard (Specification System Redundancy

Prerequisites for the ET 200M
Installation on active bus modules
The bus module 6ES7 195-7HD10-0XA0 ensures a high level of availability for
the ET 200M and shorter switchover times in the case of redundancy.
2 IM 153-2 on bus module BM IM/IM
The rules given in Section 4.1.4 apply for the used active bus modules and
interface modules.
Possible with the IM 153-2/-2 FO as of 6ES7 153-2AA02/-2AB01
In redundant mode, the SYNC/FREEZE function should not be activated.
Note
If the SYNC/FREEZE function is activated in a redundant system, the user must
assume responsibility for the resulting behavior of the H system (e.g. at
switchovers).
In a redundant system you can only use the IM 153-2 on DP masters that
support the fail-safe parameter. The IM 153-2 will not start up on DP masters
that don’t support this parameter, and the BF LED flashes.
Tip: You can tell from the DDB file of the DP master whether it supports the
fail-safe parameter or not.

Identical Versions
If you use the ET 200M in a redundant configuration, you must use compatible
versions of the IM 153-2 and IM 153-2 FO.
You can replace compatible versions of the IM 153-2/IM 153-2 FO in the case of
configuration modification in RUN without switching off the I/Os. Compatible
versions are:
IM 153-2BA00 and IM 153-2AA02, as of version 05

Configuration Options with the ET 200M
Configuration with Device Master File
Principle
With the IM 153-2Bx00, a configuration modification in RUN is also possible when
configuring with device master file. In this case, modules are added to or removed
from an ET 200M during operation. Existing modules and modules which are not to
be modified are unaffected.
During this reconfiguration process, the two IM 153-2 modules temporarily use
different configuration data. The redundant operating mode for the unaffected
modules is, however, retained.
Prerequisites
”Configuration modification in RUN” must be enabled during configuration. This
must be performed for both IM 153-2 modules of the redundant system. If this
is not the case, one of the IM 153-2 modules will not start, i.e. redundancy
mode will not be possible.
Note
If configuration modification in RUN is not enabled, parameterization and
configuration must be identical for the two IM 153-2 modules.
The parameters ”Startup If Preset Configuration 0 Actual Configuration” and
”Module Change During Operation” must be enabled for both IM 153-2
modules.
The slots for modules which are to be added must be available on the active
backplane bus. Adding or removing active bus modules is not possible during
operation.
Rules
3-12
At the I/Os of an ET 200M, it is always the configuration of the currently active
IM 153-2 which is applicable.
If there is a difference between the configurations of the two IM 153-2 modules,
the passive IM 153-2 delivers the fixed value ”zero” as input data for all inputs.
The passive IM 153-2 does not deliver the real input data again until the
configurations are identical.
Distributed I/O Device ET 200M
EWA-4NEB780600602-06
Configuration Options with the ET 200M
Configuration modification procedure
Reconfiguration is performed in the following way (example):
1. Make the appropriate modifications to the configuration offline (remove or add
module).
Note
The parameters of a module can only be changed by making two configuration
modifications in RUN:
1. Remove the module.
2. Add the module with new parameters.
3. Switch one master of the redundant system to passive (all slaves are active at
the other master).
4. Load the configuration in the master on the passive line and restart the
master →
The parameters and configuration data are loaded in the slave.
5. Switch over to the line with the new configuration →
The previously loaded configuration now becomes effective. Removed modules
are taken out of the data communication and added modules with the new
parameters are included in the data communication.
6. The changes are checked by the user.
If the changes are OK, the new configuration must also be loaded in the second
master. If the changes are not OK, the previous status can be restored by
switching over to the second master (with the old configuration). In this case,
the old configuration must be loaded on the first master again.
Note
A reconfigured module can be removed and inserted both before and after
configuration modification in RUN. The module does not become available for the
process until it has actually been inserted and the IM 153-2 which contains the
configuration for the module is active.

Configuration Options with the ET 200M
Attention
It is the user’s responsibility to ensure that the configuration within the master
system is uniform. The system does not indicate whether the two IM 153-2
modules are operating with different configurations.
If the two masters in the redundant system have different configurations, a
configuration modification in RUN is carried out whenever a switchover is
performed.
Interrupts and diagnoses which the active IM 153-2 generates for an I/O module
are reported to the master by the passive IM 153-2, even if this module does not
exist in the configuration of the passive IM 153-2. The user must decide which
interrupts and diagnoses from the passive IM 153-2 he should ignore during the
time period of different configuration data.

3.7
Clock Synchronism
Reproducible response times (i.e. response times with identical length) are
implemented in the SIMATIC using the equidistant DP bus cycle, synchronization
of the user program with the DP bus cycle, and clock-synchronized transmission of
the I/O data to the I/O modules. The clock-synchronized components of the user
program are processed using the clock-synchronized interrupts (OB 61 to OB 64)
synchronously to the DP bus cycle. The I/O data is transferred to the I/O modules
via the backplane bus of the DP slave at defined and constant
(clock-synchronized) intervals and switched through to the ”terminal” with clock
synchronism.
Clock synchronism therefore results in the synchronization of all free-running single
cycles (from the user program in the CPU, through the DP cycle on the
PROFIBUS subnetwork and right up to the cycle in the I/O modules of the DP
slaves).
The maximum jitter is 10 µs.
Features
In equidistance mode, the transition into data exchange at startup can be
delayed by up to 150 DP cycles compared to the mode without clock
synchronism.
With asynchronous events (e.g. removal and insertion, diagnoses and interrupts
of I/O modules), the response of the IM 153-2 to the I/Os can fail for one clock
cycle.
To be able to process diagnoses and interrupts without clock cycle failure, the
interval between Ti and To must be increased to at least 500 µs. Increasing the
interval beyond this minimum further improves the performance of
asynchronous events. As a general guideline, you should increase the interval
by 500 µs for every asynchronous event which is be processed simultaneously
(diagnosis, interrupt, data record).
The clock synchronism adjusts automatically following a failure.
Deactivating the watchdog has no effect with clock synchronism.
Note
Output of the IM 153-2 at the I/O modules and input of the I/O modules at the
IM 153-2 are only performed with clock synchronism if no bus modules are active.
With active bus modules, there is a time offset depending on the slot used by the
I/O module in the ET 200M.

Prerequisites

STEP 7 V5.2 or higher
PROFIBUS-DP must have a data transfer rate of at least 1.5 Mbaud (low
equidistance times can be achieved using high baud rates).
The maximum equidistance cycle is 32 ms.
The equidistance master must be a DP master of class 1, i.e. a PG/PC cannot
be an equidistance master.
In equidistance mode, only one DP master (class 1) can be active on the
PROFIBUS-DP. PGs and PCs (class 2) can be connected additionally.
The clock synchronism can only be activated at the ET 200M if the equidistant
bus cycle has been activated on the DP master system and at least one module
with synchronization support has been configured.
Optimizing the Equidistance Time
3-16
The longest (parameterizable) delay for the digital input/output modules
determines the length of the equidistant DP cycle.
Tip: With clock synchronism, make sure that all of the digital modules in the
ET 200M station have the same delay.
The smaller the input delays are that you set for the digital input modules, the
shorter the possible equidistance times will be.
Tip: Wherever possible, set an input delay of 0.1 ms for the digital input
modules.
In the case of modules which support clock synchronism, the processing time at
the module must also be taken into consideration.
The minimum possible equidistance times in the station depend on the number
of modules in the ET 200M.
You can also achieve small equidistance times if you distribute the modules of
an ET 200M (with a large number of modules) between two ET 200M stations.
The equidistance time is reduced if you increase the baud rate.
Tip: Set the highest possible baud rate.

With IM 153-2 (6ES7 153-2Bx00-0XB0), the use of active bus modules is not
intended for clock-synchronized operation since the synchronization conditions for
this application are fulfilled by certain modules only.
If active bus modules are to be used despite this, the user must include an extra
time of 500 µs for both Ti and To, therefore adding 1 millisecond to the equidistant
DP cycle.

Identification Data
Identification data is information stored in a module and supports the user when
eliminating faults in a system
checking the system configuration
locating hardware modifications in a system
The identification data allows modules to be clearly and unambiguously identified
online. As of IM 153-2Bx00 this data is available on the ET 200M.
In STEP 7 the identification data is displayed in the tabs ”Module
Status – IM 153-2” and ”Properties – DP Slave”.
Reading the Identification Data
The user can access specific identification data using Read Data Record. The
data is accessed in two stages:
1. A directory containing the data record numbers for the various indices is stored
in data record 248 (see Table 3-1).

Fiber-Optic Network with the IM 153-2 FO
In this section we show you a sample configuration of a fiber-optic network without
considering the function performed by the IM 153-2 FO.
Sample Configuration
Figure 3-10 shows an example of how a fiber-optic network is configured with the
ET 200M and the IM 153-2 FO as the slave interface.
Note the following points when using a fiber-optic network with nodes with
integrated fiber-optic interfaces:
The fiber-optic network can be set up as a line or star-type configuration.
If you remove the fiber-optic cable from an integrated fiber-optic interface, the
following nodes will also no longer be accessible:

Direct Communication
As of STEP 7 V 5.0 you can configure direct communication for the PROFIBUS
nodes. The IM 153-x can participate in direct communication as the sender
(publisher).
Principle
Direct communication is characterized by the fact that the PROFIBUS-DP nodes
listen in to find out which data a DP slave is sending back to its DP master.
Using this function the eavesdropper (recipient) can directly access changes in the
input data of remote DP slaves.
During configuration in STEP 7, in addition to defining the relevant I/O input
addresses, you can also define which of the recipient’s address areas the required
data from the sender will be read to.
Example
Figure 3-11 gives an example indicating which direct communication relationships
you can configure with an ET 200M as the sender and which nodes can listen in as
possible recipients.

Open Modules
The modules of an ET 200M are open equipment. That means you can only install
the ET 200M in housings, cabinets or electrical operating areas. These housings,
cabinets and electrical operating areas should only be accessible by means of a
key or a special tool. Only trained or authorized personnel should have access to
the housings, cabinets or electrical operating areas.

Clearance Measurements
Rules
If you adhere to the minimum clearance measurements:
You will ensure that the S7-300 modules do not get too hot.
You will have adequate space for inserting and removing the S7-300 modules.
You will have sufficient space for running cables.
If you use a shield contact element, you can connect shielded cables directly
with the rail (see Section 5.2.4). This increases the height of the S7-300
mounting rack to 185 mm. You must, however, still maintain a clearance of
40 mm.
Clearance Measurements
Figure 4-2 shows you the clearance measurements to nearby cable ducts,
apparatus, cabinet walls etc. for an ET 200M installation.
If you use a shield contact element, the dimension specifications apply from the
lower edge of the shield contact element.

Arrangement of the Modules in an ET 200M Configuration
Rules
The following rules apply to the arrangement of the modules in an ET 200M:
An ET 200M can only be installed on one mounting rack (rail), because coupling
to other mounting racks via interface modules is not permissible.
A maximum of 8 signal modules, function modules or communication
processors can be installed to the right of the IM 153-x.
Figure 4-3 shows the arrangement of the modules in an ET 200M configuration
with eight S7-300 modules.

Installation in an Intrinsically Safe Area
If you use the ET 200M in intrinsically safe areas, you must insert a DM 370
dummy module between the IM 153-x and the modules in the intrinsically safe
area. This is the only way to adhere to the required thread length (see also the
Intrinsically Safe I/O Modules) Reference Manual.
4.1.4
Rules for Configuring the ”Module Change During Operation”
and ”Redundancy” Functions
Rules
The following rules apply in addition to those listed in Section 4.1.3:
You must insert the IM 153-x and all SMs/FMs/CPs on active bus modules.
For redundancy with IM 153-2 you must insert the interface module on the
active bus module BM IM/IM in the following way:
IM 153-2

functionality of IM 153-2AA02/
-2AB01.
The new functions of the
IM 153-2Bx00 are only provided
with this bus module.
Note
The active bus module 6ES7 195-7HD10-0XA0 has two yellow markings to aid
identification. These markings indicate that only IM 153-2Bx00 modules should be
inserted on this bus module.

Are you Installing a 2-Meter Rail?
If not, you can skip this section and read on from the section entitled
Dimensioned Drawing for Fixing Holes.
If so, the 2-meter rail has to be prepared for installation.
Proceed as follows:
1. Shorten the rail to the required length.
2. Mark out:
– Four holes for fixing screws (for dimensions, see Figure 4-5 and
Table 4-1)
– A hole to take the fixing screw for the protective conductor.
3. Is the rail longer than 830 mm?
If so: You must make additional holes for more fixing screws to ensure the rail is
secure.Mark out these holes along the groove in the middle section of the rail
(see Figure 4-5). These additional holes should be at 500 mm intervals.
If not: No further steps must be taken.
4. Drill the marked holes to a diameter of 6.5 +0.2 mm for M6 screws.
5. Tighten the M6 screw to fix the protective conductor.

Installing the Rail
To install the rail, proceed as follows:
1. Choose a position for the rail that leaves enough room to install it properly and
enough space to cope with the temperature rise of the modules (leave at least
40 mm free above and below the rail; see Figure 4-2 on page 4-3)
2. Screw the rail to its base (size: M6). Is this base a metallic plate or a grounded
supporting plate?
If so: Make sure there is a low-impedance connection between the rail and the
base. In the case of painted or anodized metals, for instance, use a suitable
contacting agent or contact washers.
If not: No particular steps are required.
3. Connect the rail to the protective conductor. An M6 screw is provided for this
purpose on the rail.
Minimum cross-section from the conductor to the protective conductor: 10 mm2.
Note
Ensure that your connection to the protective conductor is low-impedance (see
Figure 4-6). If the ET 200M is mounted on a hinged rail, for example, you must
use a flexible cable to establish the connection to the protective conductor.
Protective Conductor Connection
Figure 4-6 shows you how to connect the protective conductor to the rail.

Installing Bus Modules and Modules
To install the active bus modules and modules, proceed as follows:
Only install the active bus modules in a de-energized state.
1. Hook the lower edge of the BM PS/IM or BM IM/IM bus module onto the rail,
press it into the rail (a), and push it to the left until it engages (b).
Are you using the 530 mm rail and the BM IM/IM?
If you insert the BM IM/IM in the right latched position, you can install a further
2 PS 307; 2A or 1 PS 307; 5A to the left of the BM IM/IM.
Latched
position
2. Hook the next bus module (bus module BM 2 40 or BM 1 80) onto the rail
and push it onto the rail. Push it towards the left bus module, so that the
module connector has contact.
3. Are you installing the ET 200M in intrinsically safe areas? If so, you must insert
the explosion-proof partition between the modules in the intrinsically safe and
intrinsically unsafe area. To do this, simply insert the explosion-proof partition
on the right-hand side guide of the bus module.
4. Hook the modules onto the rail and swing them down into place. Use the side
guides of the bus modules to do this. When you screw in the modules, fix the
bus module to the rail at the same time
5. Plug the bus module cover onto the last bus module. If there is a slot with no
module, plug in the backplane bus cover on the unoccupied slot.

!
4.2.4
Warning
When you insert output modules, uncontrolled system states may occur.
This is also the case when you plug in input/output modules at an angle onto the
bus module.
When you plug in an output module, the outputs set by the user program
immediately become active!
We recommend that you set the outputs in the user program to ”0” when you
remove an output module.
If modules are removed and plugged in incorrectly, neighboring modules may be
affected via the backplane bus!
After Installation
Assigning Slot Numbers
After installation you can assign a slot number to each module. This makes it
easier to assign the modules in the configuration table in STEP 7 or in COM

Connecting the Bus Connector
Proceed as follows to connect the bus connector:
1. Plug the bus connector into the IM 153-x.
2. Screw the bus connector tight on the IM 153-x.
3. If the bus connector is at the beginning or the end of a segment, you must
connect the terminating resistor (switch position ”ON”).
Alternatively, you can use the PROFIBUS terminator as an active bus
terminating element.
4. Lay the interconnecting cable(s) to the designated area for the IM 153-x,

Connecting the Fiber-Optic Cable to the IM 153-2 FO
Accessories Required:
Pack of Simplex connectors and polishing sets (6GK1 901-0FB00-0AA0)
Pack of plug-in adapters (6ES7 195-1BE00-0XA0)
Tool for removing the cable sheath (6GK1 905-6PA10)
Installing Connectors
1. Remove approximately 30 cm of the sheath from the fiber-optic duplex cable.
2. Install the fiber-optic duplex cable with the associated Simplex connectors.
You can find detailed installation instructions for the Simplex connectors in the
”SIMATIC NET PROFIBUS Networks” manual.
IMPORTANT: The polished and smoothed surface of the plastic fibers must be
absolutely smooth and even. The plastic sheath must not stick out or be cut
unevenly. If this is not the case, considerable attenuation of the light signal via
the fiber-optic cable may occur!
3. Place the Simplex connectors in the plug-in adapter for the IM 153-2 FO and
the fiber-optic cable in the cable guides provided. Insert the plug-in adapter until
you hear the sides clearly latch into position.
Make sure when you insert the plugs in the plug-in adapter that the sender is
always at the top and the recipient is underneath!

Reusing Fiber-Optic Cables
Note
If you insert used fiber-optic cables in the plug-in adapter again, you must cut off
the bent lengths of both fiber-optic cable cores and install the Simplex connectors
again.
This avoids any attenuation losses due to parts of the cores of the fiber-optic
duplex cables being bent again and overstressed.
Inserting the Fiber-Optic Cables into the IM 153-2 FO
Insert the fiber-optic cables and attached plug-in adapters into the IM 153-2 FO.
Move the protruding handle of the plug-in adapter upwards.
Make sure the positioning is correct: the sender fiber-optic cable is plugged into the
recipient socket and the recipient fiber-optic cable is inserted into the sender
socket of the fiber-optic interface of the IM 153-2 FO.
If the IM 153-2 FO is the last node in the fiber-optic network, you must close the
unoccupied fiber-optic cable interface with filler connectors (the connectors are
already in place when the IM 153-2 FO is delivered).

Introduction
In this chapter we show you how to configure the electrical installation and how to
wire an ET 200M.
To set up an ET 200M, you must take into account the mechanical configuration.
Make sure you also read Section 4.1.
Basic Rules
In view of the many and varied applications of an ET 200M, this chapter can only
describe a few basic rules on its electrical configuration. You must observe at least
these basic rules if you want your ET 200M to operate faultlessly and satisfactorily.
PNO Installation Guidelines
With PROFIBUS networks, make sure you follow the PROFIBUS
Nutzerorganisation (user organization) Installation Guidelines for
PROFIBUS-DP/FMS. These contain important information on cable routing and
the commissioning of PROFIBUS networks.

General Rules and Regulations on Operating an ET 200M
Depending on the particular area of application, the ET 200M programmable
controller, as part of a plant or system, requires that you observe a number of
specific rules and guidelines.
Note the safety and accident prevention regulations that apply to specific
applications (e.g. machinery directives).
This section outlines the most important rules you must observe to integrate your
ET 200M safely into an existing plant or system.
EMERGENCY STOP Devices
EMERGENCY STOP devices complying with IEC 204 (which corresponds to
DIN VDE 113) must remain effective during all the operating modes of the plant or
system.

Note on Radio Interference
When several electronic components are used within a switch cabinet, the radio
interference can overlap. As a result, the permissible level of radio interference
intensity in the overall configuration may be exceeded.
Tip: Space these modules out as much as possible and, if necessary, use shielded
cables or filters in the supply lines or switch cabinets with greater resistance to
radio frequency.

Rules on the Power Consumption and Power Loss of an ET 200M
The S7-300 modules get the power they need for operation from the backplane
bus and, if necessary, from an external load power supply.
The power consumption of all the signal modules from the backplane bus must
not exceed the power the IM 153-x can deliver to the backplane bus.
The PS 307 power supply is dependent on the power consumption from the
24V load power supply; this is made up of the total power consumption of the
signal modules and all other connected loads.
The power loss of all the components in a cabinet must not exceed the
maximum thermal rating of the cabinet.
Tip: When establishing the required dimensions of the cabinet, ensure that the
temperature inside the cabinet does not exceed the permissible 60 C even
where external temperatures are high.
You will find the values for the power consumption and power loss of a module
under the technical specifications of the relevant modules.

5.1.2
Operating the ET 200M with Process I/O Modules on a
Grounded Supply
This section contains information concerning the overall configuration of an
ET 200M system with a grounded incoming supply (TN-S system). The specific
subjects discussed are:
Circuit-breaking devices, short-circuit and overload protection in accordance
with DIN VDE 0100 and DIN VDE 0113
Load power supplies and load circuits.
Definition: Grounded Supply
In a grounded supply, the neutral conductor of the system is grounded. A simple
ground fault between a live conductor and ground or a grounded section of the
plant causes the protective devices to trip.
Components and Protective Measures
Various different components and protective measures are prescribed when setting
up an entire plant. The types of component and the degree to which the protective
measures are binding depend on the DIN VDE regulation that applies to your plant
setup. The following table refers to Figure 5-1.

With high output voltage ripple we recommend that you provide a supporting capacitor. Rating: 200 mF per 1A
load current (in the case of full-wave
rectification).
Rule: Ground Load Circuits
Load circuits should be grounded.
The common reference potential (ground) guarantees full functionality. Provide a
detachable connection to the protective conductor on the load power supply
(terminal L- or M) or on the isolating transformer (Figure 5-1, ). In the event of
power distribution faults, this makes it easier to localize ground faults.

5.1.3
Configuring the ET 200M with Ungrounded Reference Potential
When the ET 200M is configured with ungrounded reference potential, any
interference current is diverted to the protective conductor via an RC network
integrated in the IM 153-x (see Figure 5-3).
See also Section 9.3 for older IM 153-x versions.
Application
In plants covering large areas, it may be necessary to configure the ET 200M with
ungrounded reference potential for ground fault monitoring purposes, for example.
This is the case, for instance, in the chemical engineering industry and in power
stations.
Terminal Connection Model
Figure 5-3 shows the configuration of an ET 200M with the IM 153-x with
ungrounded reference potential. If you do not want to ground the reference
potential, you must remove the jumper on the IM 153-x between the M terminals
and functional ground. If the jumper is not in place, the reference potential of the
ET 200M is connected internally to the protective conductor via an RC combination
and via the rail. This discharges radio-frequency interference current and precludes
static charges.

Wiring
Filtering the 24V DC Supply
If you supply the IM 153-x from a battery without grounding the reference potential,
you must suppress interference on the 24 V DC supply. Use an interference
suppression device from Siemens such as B84102-K40.
Insulation Monitoring
If dangerous plant conditions can arise as a result of double faults, you must
provide some form of insulation monitoring.
5.1.4
Configuring the ET 200M with Galvanically Isolated Modules
Definition
In configurations with isolated modules, the reference potentials of the control
circuit (Minternal) and load circuit (Mexternal) are electrically isolated (see also Figure
5-4).
Application
You use isolated modules for the following:
All AC load circuits
DC load circuits with separate reference potential, e.g.:
– DC load circuits whose sensors have different reference potentials (for
example, if grounded sensors are located at some considerable distance
from the control system and no equipotential bonding is possible)
– DC load circuits whose positive pole (L+) is grounded (battery circuits).
Isolated Modules and Grounding Concept
You can use isolated modules irrespective of whether the reference potential of the
ET 200M is grounded or not.

Wiring the Power Supply and IM 153-x
Power Cables
To wire the power supply, use flexible cables (see Table 5-2 on page5-13).
If you use only one cable per connection, you don’t need an end ferrule.
Jumper
Use the jumper when wiring the PS 307 power supply module to the IM 153-x. The
jumper comes with the power supply module.
Other 24 V Connections
Above the jumper on the power supply PS 307 there are still a number of free 24 V
connections for the supply to the S7-300 I/O modules.
Wiring the 24 V Connections with a Redundant Configuration with 2
IM 153-2
Note
If you reverse the polarity of L+ power supply when wiring the IM 153-2 in a
redundant configuration, short-circuiting will occur via the frame connection. The
reason for this: Both IM 153-2 have a common ground cable via the bus module
BM IM/IM.
With IM 153-2AA02/-2AB01:
In a redundant configuration we recommend that you fuse the L+ supply before
the IM 153-2 with 2.5 A.
With IM 153-2Bx00:
In configurations with ungrounded reference potential (jumper between M and
functional ground removed, see Figure 5-3), an internal electronic fuse which
regenerates after approx. 30 seconds is triggered in the event of polarity
reversal.
In configurations with grounded reference potential (jumper inserted between M
and functional ground), the short-circuit current flows through these jumpers
and the functional grounds in the event of polarity reversal.
The IM 153-2 is not damaged if fuse protection configured for the cross-section
of the connecting cable is provided upstream of the module.

You can find the order numbers in Appendix A.
Spring Terminals
To wire the front connector using spring terminals, simply insert the screwdriver
vertically into the opening with the red opening mechanism, put the cable into the
correct terminal, and remove the screwdriver.
Tip: There is a separate opening for test probes up to 2 mm in diameter to the left
of the opening for the screwdriver.
Wiring for Module Change During Operation
If you wire modules for an ET 200M with the ”module change during operation”
function, you will require longer cables to the front connectors in order to easily
insert and remove the modules during ET 200M operation. We recommend you
make the wiring to the front connector approx. 20 cm longer.

Preparing the Connector for Wiring
To prepare for wiring, proceed as follows:
!
Warning
Accidental contact with live conductors is possible, if the power supply module and
any additional load power supplies are switched on.
Make sure the ET 200M is de-energized before doing any wiring!
1. Open the front door.
2. Put the front connector in the wiring position.
To do this, push the front connector into the signal module until it snaps into
place. The front connector still protrudes from the module in this position.
An advantage of the wiring position is that it makes wiring easier; in the wiring
position a wired front connector has no contact with the module.
Figure 5-7 shows you how to get the front connector into wiring position.

3. Strip the insulation off the cables (see Table 5-3 on page 5-14)
4. Do you want to use end ferrules?
If so: Press the end ferrules and the cables together

Do you want to bring the cables out at the bottom of the module?
If so:
Start with terminal 20, and wire the
terminals in the following order:
terminal 20, 19, ... 1.
Starting at terminal 40 or 20, wire the
terminals alternately (i.e. terminals 39,
19, 38, 18 etc. down to terminals 21
and 1).
If not:
Start with terminal 1, and wire the
terminals in the following order: terminal
1, 2, ... 20.
3.
Also tighten the screws of any terminals that are not wired.
4.
5.
Starting at terminal 1 or 21, wire the
terminals alternately (i.e. terminals 2, 22,
3, 23 etc. up to terminals 20 and 40).
–
Thread the cable strain-relief assembly
into the front connector.
Pull the cable strain-relief assembly tight. Push the retainer on the strain-relief
assembly in to the left; this will improve utilization of the available space.

Connecting Shielded Cables via a Shield Contact Element
Introduction
This section tells you how to connect the shield of shielded signal lines to ground
via a shield contact element. The connection to ground is achieved by direct
contact between the shield contact element and the rail.
Application
You can do the following easily with the shield contact element:
Connect all S7-300 module shielded cables to ground
Connect the interconnecting cable to ground.
Design of the Shield Contact Element
The shield contact element consists of the following parts:
A mounting bracket with two bolts for attaching the element to the rail (Order
No.: 6ES7 390-5AA00-0AA0)
The shield terminals
Depending on the cable cross-sections used, you must use the following shield
terminal:
Table 5-6
Assignment of cable cross-sections and terminal elements
Cable and shield diameter

Order no.:
2 cables with a shield diameter of 2 to
6 mm each
6ES7 390-5AB00-0AA0
1 cable with a shield diameter of 3 to
6ES7 390-5BA00-0AA0
1 cable with a shield diameter of 4 to 13 mm
interconnecting cable
6ES7 390-5CA00-0AA0
The shield contact element is 80 mm wide with space for two rows each with
4 shield terminals.

Wiring
Installing the Shield Contact Element
Install the shield contact element as follows:
1. Push the two bolts of the fixing bracket into the guide on the underside of the
rail. Position the fixing bracket under the modules to be wired.
2. Bolt the fixing bracket tight to the rail.
3. A slotted web is arranged at the bottom side of the terminal element. Place the
shield terminal at this position onto the edge of the fixing bracket (see
Figure 5-8). Press the shield terminals down and swing them into the desired
position.
You can attach up to four terminal elements on each of the two rows of the
shield contact element.

Figure 5-8
Attaching shielded 2-wire cables to a shield contact element
Attaching Cables
You can only attach one or two shielded cables per shield terminal (see Figure 5-8
and Table 5-6). The cable is connected by its bare cable shield. There must be at
least 20 mm of bare cable shield. If you need more than 4 shield terminals, start
wiring at the rear row of the shield contact element.
Note
Use a sufficiently long cable between the shield terminal and the front connector.
This enables you to remove the front connector without removing the shield
terminal.

Notes
If you configure the IM 153-x from the STEP 7 hardware
catalog, unlimited S7 functionality is available to you
(for example, removal/insertion interrupts on the DP
master for module change during operation or forwarding
of the parameterization data to the FM or HART modules)
If you can’t find your IM 153-x version in the hardware
catalog, integrate the device master file in STEP 7.
COM PROFIBUS
w Version 3.0
You have integrated the IM 153-x together with the device
master file in the COM PROFIBUS.
COM PROFIBUS supports the device master file up to
revision 2.
You can use the device master file revision w 3 for
configuration, but the new functions of the IM 153-2Bx00
are then not supported.1

Agreement in the case of Redundancy:
In the case of redundancy, the two inserted IM 153-2 modules operate
independently of one another.

Actions Following Diagnostic Message in S7 or DPV1 Mode
Every diagnostic message triggers the following actions:
In S7 or DPV1 mode, diagnoses are reported as diagnostic interrupts.
In DPV1 mode, diagnoses are also reported when the master CPU is in STOP
mode. The diagnostic frame also contains the module status and the
channel-specific diagnosis.
Following a diagnostic message, it is
– entered in the diagnostic frame as a diagnostic interrupt block (only one
interrupt at any one time)
– stored in the diagnostics buffer of the master CPU
The SF LED on the IM 153-x lights up.
OB 82 is called in the master CPU. If OB 82 is not available, the master CPU
enters the STOP mode.
Acknowledgment of the diagnostic interrupt by the master CPU (a new
diagnostic interrupt is then possible).
Actions Following Diagnostic Message in DPV0 Mode
The error is entered in the channel-specific diagnosis in the diagnostic frame:
The SF LED on the IM 153-x lights up.
Several diagnostic messages can be issued at the same time.

Structure of the Diagnosis
Introduction
The IM 153-x makes the standard slave diagnosis available to you. Note the
differences in the diagnostic frame depending on which version of IM 153-x and
which release you have.
Depending on the DP master and parameter assignment, the following can provide
an enhanced diagnosis:
IM 153-1 as of 153-1AA03, version 02, DDB version V1.18;
IM 153-1 as of 153-1AA83, version 01, DDB version V1.18;
IM 153-2 as of 153-2AA02, version > 06, DDB version V1.9;
IM 153-2 FO as of 153-2AB01, version > 05, DDB version V1.5.
IM 153-2 as of 153-2AA00, version > 01, DDB version V1.0;
IM 153-2 FO as of 153-2AB00, version > 01, DDB version V1.0
You can find detailed information in the diagnostic frame in the form of the module
status and channel-specific diagnoses (see Figure 6-5 on Page 6-18).

Structure of the Slave Diagnosis
Notes on Enhanced Diagnosis
To use channel-specific diagnosis, you must enable the diagnostic interrupt in each
I/O module using parameter assignment.
When you parameterize the IM 153-x, you can enable or disable the diagnostic,
process and insert/remove module interrupts regardless of whether or not the
enhanced diagnosis is enabled.
Using the DPV1 parameters (as of device master file rev. 3) you can disable and
enable the individual blocks of the enhanced diagnosis. Disabled diagnoses are
removed from the diagnostic frame.
Important: If you have enabled enhanced diagnosis during parameter assignment
and do not enable diagnostic interrupts for a module until the ET 200M is in
operation, a channel fault will not be entered in the diagnostic frame immediately.
Not until the first diagnostic interrupt of the module is triggered after being enabled
will a channel fault be entered in the diagnostic frame.
To delete channel faults from the diagnostic frame, you must disable enhanced
diagnosis.
With IM 153-2Bx00
With the IM 153-2Bx00, the enhanced diagnosis is available by default in
DPV0/DPV1 mode. It can be deselected (disabled) in blocks during
parameterization.

Channel-Specific Diagnosis
Definition
The channel-specific diagnosis gives information on channel errors of modules and
expands on the module diagnosis.
The channel-specific diagnosis begins after the module status or after
the H status. (see Section 6.4.8)
The channel-specific diagnosis does not affect the module status.
Important: The diagnostic interrupt must be switched on for each module!
Channel-Specific Diagnosis
The channel-specific diagnosis is only contained in the diagnostic frame if you
have enabled enhanced diagnosis during parameter assignment.
The maximum number of channel-specific diagnoses is limited by the maximum
overall length of the slave diagnosis of 64 bytes in the IM 153-1 and 96 bytes in the
IM 153-2. The length of the slave diagnosis depends on the number of currently
pending, channel-specific diagnoses. If there are more channel-specific diagnoses
than can be represented in the slave diagnosis, bit 7 (diagnostic overflow) is set in
station status 3.
Tip: If you disable the interrupts for the ET 200M during parameter assignment,
there are still up to 29 additional bytes available in the interrupt section for the
channel-specific diagnosis (see also Figure 6-5 on Page 6-18).

Interrupts
Definition
The interrupts section of the slave diagnosis provides information on the type of
interrupt and the cause that triggered the interrupt.
The interrupt section has a maximum of 29 bytes.
A maximum of one interrupt can be used per slave diagnosis.
Position in the Diagnostic Frame
The position of the interrupt section in the slave diagnosis depends on the
structure of the diagnostic frame and on the number of channel-specific diagnoses
(see also Figure 6-5 on page 6-18): The interrupt component is always the last part
of the diagnostic frame.
Contents
The contents of the interrupt information depend on the type of interrupt:
In the case of diagnostic interrupts, the diagnostic data record 1 for SIMATIC S7
(e.g. 16 bytes) is sent as interrupt information (as of byte x+4). You can find out
what these bytes mean for digital and analog modules in Figures 6-12 to 6-15
(pages 6-33 to 6-36).
In the case of process interrupts, the additional interrupt information is 4 bytes
long. You can find out what these bytes mean in Figures 6-16 and 6-17 (pages
6-37 and 6-37).
In the case of cycle-end interrupts, these bytes are always FFH.
In the case of insertion/removal interrupts the additional interrupt information is
5 bytes long. You can find out what these bytes mean in Figure 6-18 (on page
6-38).

Removal and Insertion Interrupts
To remove and insert modules during operation, you must configure the ET 200M
with active bus modules (see Section 4.1.4 in the manual). Use the switch for the
removal/insertion interrupt to parameterize whether removal/insertion events are to
be reported as interrupts in the diagnostic frame. If you disable removal/insertion
interrupts, you can still remove and insert modules in the configuration with active
bus modules. These events then appear in the module diagnosis and the module
status exclusively. See also Section 9.1 and 9.2 to find out how the older IM 153-x
versions respond.
In a configuration without active bus modules, removing and inserting modules will
result in station failure.
Note: Inserting or removing a DM 370 dummy module does not trigger an insertion
or removal interrupt.
Diagnostic Interrupt
If there is a diagnostic event for channel/channel group 0 of a module, there may
be a module error as well as a channel error (see record 0 in Figure 6-11 on page
6-32). The entry is made in this case even if you have not enabled the diagnosis
for channel/channel group 0 of the module.

Evaluating Interrupts from the Station Diagnosis
The structure of the station diagnosis is the same as the structure of the interrupt
section, as described in Section 6.4.9.
Interrupts with S7/M7-DP Master or DPV1 Master
The ET 200M supports the following interrupts:
Diagnostic interrupt
Process interrupt
Module insertion/removal interrupt.
You can evaluate these interrupts with an S7/M7-DP master or DPV1 master. In
the case of an interrupt, interrupt OBs run automatically in the master CPU (see
the System Software for S7-300/S7-400, Program Design Program Manual).

Commissioning and Diagnostics
Removal/Insertion Interrupt with S7/M7-DP Master or DPV1 Master
If you use the ET 200M with ”module change during operation” on an S7/M7-DP
master or a DPV1 master, the system behaves as follows:
When a module is removed, the IM 153-x reports a module removal interrupt on
the DP master that executes OB 83. You program the desired response to the
module removal event in OB 83.
In the case of I/O access, OB 122 (I/O access error) is called in the DP master.
If you insert a module that corresponds to the configuration, the IM 153-x
reports a module insertion interrupt to the DP master (OB 83 call with
diagnostics buffer entry) and assigns parameters to the module in keeping with
the stored configuration.
If you insert a module in an unconfigured slot, the IM 153-x doesn’t report a
module insertion interrupt.
If you insert a different module than configured:
– the IM 153-x reports a module insertion interrupt to the DP master (OB 83
call with diagnostics buffer entry); but it ignores this unconfigured module.
– The module diagnosis is stopped, and you can read out the slot in which the
wrong module is inserted (see Section 6.4.5).
– The SF LED shows the error.
Note: Inserting or removing a DM 370 dummy module does not trigger an insertion
or removal interrupt.
!
Warning
Problems during removal and insertion are tolerated for up to 1 second.
This means that the output values will not change within the tolerance time in the
event of such a problem occurring.

EWA-4NEB780600602-06

Commissioning and Diagnostics
Interrupts with Another DP Master
If you operate the ET 200M with another DP master, these interrupts are simulated
as a device-specific diagnosis of the ET 200M. You must postprocess the relevant
diagnostic events in the DP master’s user program.
Saving the Diagnosis
Depending on byte x+1, transfer the contents of the station diagnosis to a data
block because:
The interrupts are updated cyclically.
The contents of the diagnosis as of byte x+3 depend on whether the S7
diagnosis or S7 process interrupt or module insertion/removal module interrupt
is reported.
Note
The following points are important in evaluating diagnostic interrupts and process
interrupts with a different DP master by means of the station diagnosis:
The DP master should be able to store the diagnostic messages, that is, the
DP master should have a ring buffer in which to place these messages. If the
DP master can not store diagnostic messages, only the last diagnostic
message will be available for evaluation.
You must scan the relevant bits in the device-related diagnostic data in your
user program at regular intervals.
You cannot use process interrupts in the station diagnosis in an IM 308-C as
DP master, because only coming – and not going – interrupts are reported. For
example, the ”upper limit violation” bit is only reset when the ”lower limit
violation” bit is set. The cycle end interrupt is not supported by the IM 308-C,
because the cycle end interrupt updates to ”1” at the end of each cycle (i.e.
there is no change in the signal level).
Module Removal/Insertion Interrupts with Other DP Masters
If you use the ET 200M with module change during operation on another DP
master, you must make sure that it cannot evaluate the module removal and
insertion interrupts. You can evaluate the module removal and insertion events in
the module and station diagnosis of the IM 153-x.
Tip: Evaluate the module status in the enhanced diagnosis.

Removing the Power Supply Module
To remove the power supply module, proceed as follows:
1. Operate the supply isolating switch in order to de-energize the power supply
module.
2. Remove the cover.
3. Disconnect all the wiring.
4. Undo the fixing screws of the power supply module.
5. Swing the power supply module out.
Installing the New Power Supply Module
To install the new power supply module, proceed as follows:
1. Check the setting of the voltage selector switch.
2. Hook the new power supply module of the same type onto the rail and swing it
down into place.
3. Screw the power supply module on securely.
4. Wire the power supply module.
5. Connect the power supply module to the line voltage.
6. Close the cover.
Response of the ET 200M After Module Replacement
If there is an error after the power supply modules have been replaced, you can
have the cause displayed in the diagnostic buffer with STEP 5 or with STEP 7.

Replacing the IM 153-1
Initial Situation
The IM 153-1 is installed. You want to install a new IM 153-1 of the same type.
Slot Numbering
If you have given slot numbers to the modules in your system, you must remove
the numbering from the old module when you replace the module and use it on the
new module.
Unplugging the Bus Connector
With a looped-through interconnecting cable you can unplug the bus connector
from the PROFIBUS-DP interface without interrupting data traffic on the network.
Note
A data communication error may occur on the network.
A network segment must always be terminated at both ends with the terminating
resistor. This is not the case, for example, if the power supply is not activated on
the last slave with a bus connector. The efficacy of the terminating resistor is
impaired because the terminating resistor in the bus connector gets its voltage
from the node.
Please make sure that power is always supplied to nodes
on which the terminating resistor is active.
Tip: You can use the PROFIBUS terminator as an active bus terminating element.
Removing a Module
To remove the module, proceed as follows:
1. Put the on/off switch of the power supply module in the 0 position ( :output
voltage 0 V).
2. Remove the bus connector.
3. Disconnect the wiring.
4. Remove the fixing screws of the IM 153-1.
5. Swing the IM 153-1 out.

In the Case of Redundancy
Note
Only replace the IM 153-2/-2 FO in a de-energized state!
If you carry out a replacement in an energized state, the specified switchover
times cannot be guaranteed and the I/O modules could fail for a certain time and
output “0”.
If you replace the IM 153-2/-2 FO in a redundant configuration, the following
applies:
”ACT” LED is on:
The IM 153-2/-2 FO is the active one of the
two IM 153-2/-2 FO modules.
”ACT” LED is off:
The IM 153-2/-2 FO is the passive one of
the two IM 153-2/-2 FO modules.
You can replace these IM 153-2/-2 FO
modules without the need for switchover
operations in the ET 200M.
Removing a Module
To remove the module, proceed as follows:
1. In the case of redundancy: The IM 153-2/-2 FO to be replaced must be
de-energized! Switch off the associated power supply module or disconnect it
from the IM 153-2/-2 FO.
!
Warning
If in redundancy mode the two IM 153-2 modules are connected to a power supply
module, a short circuit could occur at the non-insulated (loose) cable ends if the
24 V supply is disconnected from one of the IM 153-2.
If the power supply is short-circuited in this way, the second IM 153-2 and
therefore your ET 200M fail completely.
The greatest care must therefore be taken when disconnecting the supply voltage
and the two cable ends must be insulated until they are connected to the new
IM 153-2.
No redundancy: Put the on/off switch of the power supply module into the 0
position ( : output voltage 0 V).
2. Remove the bus connector or fiber-optic cable.
In the case of fiber-optic cables: Flip open the grip of the plug-in adapter and
remove it from the IM 153-2 FO.

3. Disconnect the wiring.
4. Remove the fixing screws of the IM 153-2/-2 FO.
5. Swing the IM 153-2/-2 FO out.
Installing a New Module
Install the new module as follows:
1. Set the same DP address on this IM 153-2/-2 FO as for the old IM 153-2/-2 FO.
2. Hook the new IM 153-1/-2 FO onto the rail and swing it down into place.
3. Screw the module on securely.
4. Wire the IM 153-2/-2 FO.
5. Screw the bus connector tight.
6. Put the standby switch of the power supply module into the 1 position (output
voltages to rated value).
Response of the ET 200M After Module Replacement
If there is an error after the modules have been replaced, you can have the cause
displayed in the diagnostic buffer with STEP 5 or STEP 7.
In the Case of Redundancy:
Note
If the active IM 153-2/-2 FO (”ACT” LED on) is replaced, the I/O system will only
continue without interruption if on the passive IM 153-2/-2 FO the BF LED neither
comes on nor flashes, or if the SF LED does not flash at 0.5 Hz (see also Table
6-6 on page6-11).
Have you replaced an active IM 153-2/-2 FO
(”ACT” LED on)?
A switchover took place in the ET 200M to the
other IM 153-2/-2 FO, and data traffic continues
between it and its DP master.
Have you replaced a passive IM 153-2/-2 FO
(”ACT” LED off)?
No change in data traffic: It continues between the
active IM 153-2/-2 FO and its DP master.
Does the new IM 153-2/-2 FO have a different version to the one that wasn’t replaced?
If after replacement, the replaced IM 153-2/-2 FO goes into STOP (all the LEDs flash), the releases are
not compatible. In this case you must switch off the ET 200M and upgrade the two IM 153-2/-2 FO or use
a compatible version.

Replacing Modules with the ”Module Change During
Operation” Function
Prerequisites
You can replace the modules during operation of the ET 200M once you have done
the following:
!
Installed the ET 200M on the rail with active bus modules for the ”module
change during operation” function.
Configured the ET 200M for the ”module change during operation” function.
Warning
When you insert output modules, uncontrolled system states may occur.
This is also the case when you insert input/output modules at an angle to the bus
modules.
When you insert an output module, the outputs set by the user program
immediately become active.
We recommend that you set the outputs in the user program to ”0” when you
remove an output module.
If modules are removed and inserted incorrectly, neighboring modules may be
affected via the backplane bus.

Response of the ET 200M
Removing a
module
–
The IM 153-x reports the removal of a module via the diagnosis. The
diagnostic event corresponds to the module removal interrupt (see
Section 6.4.9). The IM 153-x also enters the removal of the module in the
module diagnosis (see Section 6.4.5).
Yes
When a configured module is inserted, the IM 153-x deletes the entry in
the module diagnosis to the effect that the module is no longer addressed
by the IM 153-x. If the ET 200M is in user data mode, the IM 153-x
reports a diagnostic event that corresponds to the module insertion
interrupt (see Section 6.4.9). The inserted module is parameterized in
accordance with the last parameter assignment and is accepted in the
ET 200M.
No
The IM 153-x ignores the inserted module.
Inserting a
module
The IM 153-x reports a diagnostic event corresponding to the module
insertion interrupt (see Section 6.4.9).
The entry concerning the removal of the module remains in the module

Maintenance
Update in the Redundant System
If the update of the active IM 153-2 is performed via PROFIBUS-DP, the reset
which is performed afterwards automatically triggers the switchover between the
two IM 153-2 modules. We recommend that you then also update the second
IM 153-2 in the redundant system. The update must be performed separately for
each IM 153-2.
Restart After Update
Update via PROFIBUS-DP
In the STEP 7 user interface, it is possible to set whether
the IM 153-2 performs a reset automatically on completion of the update in
order to start up with the newly loaded firmware
Caution
If the ”Update Firmware After Loading” box is selected, there will be a brief station
failure of the ET 200M. If no precautions have been taken to counter this, the
update causes the CPU to enter STOP mode owing to rack failure.
the IM 153-2 is to be reset by switching off the supply voltage before the
IM 153-2 starts up with the new firmware when the supply voltage is switched
on again.
Update via MMC
On completion of the update, the IM 153-2 remains in a state which can only be
left by switching off the supply voltage. If the update was successful, the IM 153-2
starts up with the new firmware the next time the supply voltage is switched on.
Update Not Successful
If the update is unsuccessful, the IM 153-2 always starts up with the currently
loaded (”old”) firmware when the supply voltage is switched off and then on again.

Time Delay of the ET 200M
Response Time – A Definition
The response time is the time between detection of the input signal and the
modification of the associated output signal.
Duration
The response time depends on the bus configuration and on the DP master. You
can find fundamentals for calculating the response time in the DP master manuals.
Factors
The response time for the ET 200M depends on the following factors:
Processing the data through the ET 200M
Delay of the inputs and outputs (see Module Specifications Reference Manual)
ET 200M
The time it takes to process the data in the ET 200M is typically 1 ms. Data
processing in the IM 153-x and the data transfer between the IM 153-x and the
inserted modules takes place in this time.

The IM 153-1 (order number 6ES7 153-1AA01-0XB0) is partially downward
compatible. This means you can also use the configuration and the user program
for the IM 153-1 (order number 6ES7 153-1AA01-0XB0) for the IM 153 (order
number 6ES7 153-1AA00-0XB0), except if SYNC and FREEZE are used in these
user programs. Note the different Min_Slave_interval (see Table 9-1).
Upgrading to 153-1AA02-...

As of
153-1AA03, version 02
The ET 200M is set up on active bus modules. The
removal/insertion interrupt is disabled at parameter
assignment.
The ET 200M is set up on active bus modules. The
removal/insertion interrupt is disabled at parameter
assignment.
The removal or insertion of a module results in
station failure.
It is still, however, possible to remove and insert
modules. An interrupt is not reported, but the
events are displayed in the diagnosis.
Startup Characteristics When Response Monitoring is Switched Off
The IM 153-1 as of 6ES7 153-1AA02-0XB0, version 05 performs differently when
the DP standard master is restarted with response monitoring switched off:
When response monitoring is switched off, the outputs of the ET 200M keep their
set values when the DP master fails.
When the DP master is restarted without resetting the DP slave these initial
values remain valid until new output data is received from the DP master.
If the DP slave is not reset, it is not enabled for other DP masters. Bit 6 of ”Octet 1:
Station_status, Unlock_Req” has the value ”0” in the parameter assignment frame
(for example, in the DP master of the
SIMATIC 505).
In the case of previous versions: When the DP master is restarted, the outputs
of the ET 200M are briefly set to ”0”, until they are reset by the DP master.
When response monitoring is switched on, the IM 153-1AA02 as of E05
behaves like the previous versions.

Configuration of the IM 153-1 with the General Identification Format
You can also configure the IM 153 (as of order number 6ES7-1AA03-0XB0,
version 2) with the general identification format (AKF). This configuration assumes
detailed knowledge of the structure of the general identification format. Use the ID
0x00 for slots 1 to 3.
!
9-4
Warning
If you carry out configuration with the general identification format, the quality of
the comparison between the desired and actual configurations at startup of the DP
slave or when modules are removed or inserted is very low. Since there is no type
ID available for the comparison, an incorrect configuration cannot be easily
detected!

Configuration of the IM 153-2 with the General Identification Format
You can also configure the IM 153-2 (as of order number 6ES7-2AA02-0XB0,
version 07, and 6ES7-2AB01-0XB0, version 06) with the general identification
format (AKF). This configuration assumes detailed knowledge of the structure of
the general identification format. Use the ID 0x00 for slots 1 to 3.
!
Warning
If you carry out configuration with the general identification format, the quality of
the comparison between the desired and actual configurations at startup of the DP
slave or when modules are removed or inserted is very low. Since there is no type
ID available for the comparison, an incorrect configuration cannot be easily
detected!
Functionality of the Previous Version
If you insert the interface module IM 153-2Bx00
on a bus module BM IM/IM (6ES7 195-7HD00-0XA0), or
if you configure the interface module IM 153-2Bx00 as IM 153-2AA02/-2AB01
using STEP 7, or
if you configure the interface module IM 153-2Bx00 with device master file
revision 2,
the interface module will have the same functionality as an IM 153-2AA02/-2AB01.

Glossary
Automation system
An automation system is a ³ programmable logic controller consisting of at least
one ³ CPU, various input and output modules and operator interfaces.
Backplane bus
The backplane bus is a serial data bus via which the modules communicate and
via which the necessary power is supplied to the modules. The connection
between the modules is established by bus connectors.
Baud rate
The baud rate of a data transfer is measured in bits transmitted per second
(baud rate = bit rate).
In the case of the ET 200, baud rates of 9.6 kbaud to 12 Mbaud are possible.
Bus
A common transmission line connecting all nodes. Has two defined ends.
In the case of the ET 200, the bus is a two-wire or fiber-optic cable.
Bus node
A device that can send, receive or amplify data via the bus, such as a DP
master, DP slave, RS 485 repeater or active star coupler.
Bus segment

Chassis ground
Chassis ground refers to all the interconnected inactive parts of a piece of
equipment that, even in the event of a fault, cannot carry voltage that is
dangerous to the touch.
Clock synchronism
With clock synchronism, all cycles concerned (e.g. user program cycle, DP bus
cycle, signal conditioning cycle in the modules of the DP slaves) run in common
mode and with identical length. As a result, the process response times are of
the same length and reproducible.
Configuration
Assignment of modules to racks/slots and addresses. A distinction is drawn
between the actual configuration (= modules actually inserted) and the desired
configuration. You can specify the desired configuration using STEP 7,
COM PROFIBUS (or COM ET 200 Windows). This way the operating system
can detect any incorrectly installed modules at startup.
Configuration modification in RUN
With a configuration modification in RUN it is possible to carry out certain
configuration modifications while a system is still in operation. Processing is
stopped for just a few seconds. During this time the process outputs retain their
current values which has virtually no effect on processing sequences in
process-oriented systems.
A configuration modification in RUN is only possible with distributed I/Os.
CPU
Central processing unit of the S7 programmable controller with open and
closed-loop control systems, memory, operating system and interface for
programming device.

Glossary
Device master file
All slave-specific
characteristics are stored in a device master file (GSD file). The format of the
device master file is defined in the IEC 61784-1:2002 Ed1 CP 3/1 standard.
Diagnostic interrupt
Diagnostics-capable modules use diagnostic interrupts to report system errors
that they have detected to the central CPU.
In SIMATIC S7/M7: When an error is detected or disappears (e. g. wire break),
the module triggers a diagnostic interrupt, provided the interrupt is enabled. The
CPU interrupts the processing of the user program and lower priority classes and
processes the diagnostic interrupt block (OB 82).
In SIMATIC S5: The diagnostic interrupt appears in the station diagnosis. Using
cyclical querying of the diagnostic bits in the station diagnosis you can detect
errors such as a wire break.
Diagnostics
Diagnostics is the detection and localizing of errors. The structure of the
diagnosis is defined in the IEC 61784-1:2002 Ed1 CP 3/1 standard. The
diagnosis of the ET 200M is in keeping with the standard.
Distributed I/O devices
These are input/output units that are not located in the base unit; instead, they
are distributed at some distance from the CPU. The following are examples of
such units:
ET 200M, ET 200B, ET 200C, ET 200U
DP/AS-I Link
S5-95U with PROFIBUS-DP slave interface
Other DP slaves from either Siemens or other vendors
The distributed I/O devices are connected to the DP master via PROFIBUS-DP.
DP master
A ³ master performing to the IEC 61784-1:2002 Ed1 CP 3/1 standard is classed
as a DP master.

Glossary
DP slave
A ³ slave run on the PROFIBUS bus system with the PROFIBUS-DP protocol
and performing to the IEC 61784-1:2002 Ed1 CP 3/1 standard is referred to as a
DP slave.
DP standard
The bus protocol of the ET 200 distributed I/O system in accordance with the
IEC 61784-1:2002 Ed1 CP 3/1 standard.
Equipotential bonding
Electrical connection (equipotential bonding conductor) that brings the parts of
electrical equipment and other conductive parts to the same or approximately the
same potential in order to prevent troublesome or dangerous voltages arising
between these parts.
External power supply
Power supply for the signal and function modules and the process peripherals
connected to them.
Fiber-optic cable
Fiber-optic cables are made of glass fiber or plastic and have an extremely high
transmission rate. They are insensitive to electromagnetic interference and are
very difficult to tap.
FREEZE
This is a control command of the DP master to a group of DP slaves.
When a DP slave receives the FREEZE control command, it freezes the current
status of the inputs and transfers them cyclically to the DP master.
After each subsequent FREEZE control command, the DP slave freezes the
status of the inputs again.
The input data is not transferred from the DP slave to the DP master again
cyclically until the DP master sends the UNFREEZE control command.

Functional grounding
Grounding which has the sole purpose of safeguarding the intended purpose of
the electrical equipment. Functional grounding short-circuits interference
voltages which would otherwise have an impermissible impact on the equipment.
Ground
The conductive mass of earth, the electrical potential of which can be set to zero
at any point.
In the vicinity of grounding electrodes the potential may not be zero. The term
”reference ground” is often used here.
Grounding
Grounding means to connect a conductive component with the grounding
electrode via a ground system.
H system
System with high availability consisting of at least two central processing units or
two separate devices, e.g. PCs (master/reserve). The user program is processed
identically in the master and reserve PCs.
Identification data
Identification data is information stored in a module and supports the user when
eliminating faults in a system
checking the system configuration
locating hardware modifications in a system
I/O bus
The I/O bus is part of the ³ S7-300 backplane bus in the programmable logic
controller, optimized for the rapid exchange of signals between the IM 153-x
module(s) and the signal modules. ³ User data (e.g. digital input signals of a
signal module) and system data (e. g. default parameter data records of a signal
module) are transferred via the I/O bus.
I/Os, single-channel
A single-channel I/O is when – in contrast to redundant I/Os – the I/O module is
available only once for a process signal. It can be connected on a one-sided or
switched basis.

IP20
Degree of protection to DIN 40050: Protection against contact with fingers and
against foreign bodies longer than 12 mm ∅.
Isolated
In the case of isolated input/output modules, the reference potentials of the
control and load circuit are galvanically isolated – by means of optical isolators or
relay contacts, for example. Input/output circuits can be grouped.
Master
When they are in possession of the token, masters can send data to and request
data from other nodes (= active node).
³ The CPU 315-2 DP and the IM 308-C are examples of DP masters.
Master-slave access method
A bus access method in which only one node is the ³ DP master and all the
other nodes are ³ DP slaves.
Non-isolated
In the case of non-isolated input/output modules, the reference potentials of the
control and load circuit are electrically connected.
Parameter assignment
Parameter assignment means setting the behavior of a module.
Parameter assignment master
Each DP slave has one parameter assignment master. During startup the
parameter assignment master transfers the parameterization data to the DP
slave. The master has read and write access to the DP slave and it can change
the configuration of a DP slave.

Process interrupt
A process interrupt is triggered by S7-300 modules with interrupt capability
because of a certain event in the process. The process interrupt is reported to
the central CPU. The assigned organization block is then processed in
accordance with the priority of this interrupt.
In SIMATIC S7/M7: As a result of the parameterization of an upper and lower
limit value, for example, an operating range is defined. If the process signal (e. g.
temperature) of an analog input module leaves this range, the module triggers a
process interrupt (assuming an interrupt is enabled). The CPU interrupts the
processing of the user program and lower priority class and processes the
process interrupt block (OB 40).
In SIMATIC PCS 7: If the IM 153-2 reports a process interrupt, there is at least
one data record containing messages concerning time-stamped signal changes
or special messages. The DP master CPU can read and evaluate the data
record(s).
In SIMATIC S5: The process interrupt appears in the station diagnosis. Using
cyclical querying of the diagnostic bits in the station diagnosis, you can recognize
process interrupts such as an upper limit violation.
PROFIBUS
PROcess FIeld BUS which is defined in the PROFIBUS
IEC 61784-1:2002 Ed1 CP 3/1 standard. It defines the functional, electrical and
mechanical properties of a bit-serial field bus system.
PROFIBUS is a bus system that networks PROFIBUS-compatible programmable
logic controllers and field devices at the cell and field level. PROFIBUS is
available with the protocols DP (the German abbreviation for distributed I/O),
FMS (= field bus message specification) or TF (= technology functions).
PROFIBUS address
Each bus node must receive a PROFIBUS address to uniquely identify it on the
PROFIBUS-DP bus system.
The PC/programming device or the hand-held ET 200 have the PROFIBUS
address ”0”.
DP master and DP slaves have a PROFIBUS address from 1 to 125.
Distributed I/O Device ET 200M
EWA-4NEB780600602-06
Glossary-7
Glossary
PROFIBUS-DP
This is the PROFIBUS bus system with the DP protocol. DP stands for
distributed I/O in German. The ET 200 distributed I/O system is based on the
IEC 61784-1:2002 Ed1 CP 3/1 standard.
Programmable controller
Programmable controllers (PLCs) are electronic controllers whose function is
saved as a program in the control unit. The configuration and wiring of the unit
are therefore independent of the function of the control system. The
programmable controller has the structure of a computer; it consists of a CPU
(central processing unit) with memory, input/output modules and an internal bus
system. The I/Os and the programming language are oriented to control
engineering needs.
Programming device
Programming devices (PGs) are essentially personal computers which are
compact, portable and suitable for industrial applications. They are equipped with
special hardware and software for SIMATIC programmable controllers.
Redundant systems
Redundant systems are characterized by the fact that important automation
components are duplicated (redundant). If a redundant component fails, there is
no interruption in the program processing.
Reference potential
Potential from which the voltages of the circuits involved can be observed and/or
measured.

EWA-4NEB780600602-06
Glossary
Response monitoring
This is a slave parameter. If a DP slave is not addressed within the response
monitoring time, then it goes into the safe status, i. e. the DP slave sets its
outputs to ”0”.
Response time
The response time is the average time between changing an input and the
consequent changing of an output.
S7 diagnostics
An S7 diagnosis can be requested for all the modules in the SIMATIC S7/M7
range of modules in the user program. The structure of the S7 diagnostic data is
the same for both central and distributed modules.
The diagnostic data of a module is in data records 0 and 1 of the system data
area of the module. Data record 0 contains 4 bytes of diagnostic data describing
the current state of a module. The data record 1 also contains module-specific
diagnostic data.
Data records 0 and 1 are included in the slave diagnosis.
Segment
The bus line between two terminating resistors forms a segment. A segment
contains 0 to 32 ³ bus nodes. Segments can be interconnected by means of
RS 485 repeaters.
Signal module
Signal modules (SMs) represent the interface between the process and the
programmable controller. Input and output modules can be digital (input/output
module, digital) or analog (input/output module, analog).
Slave
A slave can only exchange data with a ³ master when requested by it to do so.
By slaves we mean, for example, all DP slaves, such as ET 200B, ET 200C,
ET 200M etc.

Glossary
STEP 7
Programming language for developing user programs for SIMATIC S7 PLCs.
Substitute value
Substitute values are values that are issued to the process in the event of failed
signal output modules or that are used in the event of failed signal input modules
in the user program instead of a process value. The substitute values must be
specified by the user (e. g. retain the old value).
SYNC
This is a control command of the DP master to a group of DP slaves.
By means of the SYNC control command the DP master causes the DP slave to
freeze the current statuses of the outputs. In the subsequent frames, the DP
slave stores the output data, but the statuses of the outputs remain unchanged.
After each new SYNC control command, the DP slave sets the outputs that it
has stored as output data.
The outputs are not cyclically updated again until the DP master sends the
UNSYNC control command.
Terminating resistor
This is a resistor required for the purpose of adaptation on the interconnecting
cable; terminating resistors are always required at the end of cables and
segments.
In the case of the ET 200, the terminating resistors are switched on and off in the
³ bus connector.
Time stamp
This is the date and time specified for a message.
Glossary-10
Distributed I/O Device ET 200M
EWA-4NEB780600602-06
Glossary
Time stamping
Binary input signals are given a time stamp when they are changed. All binary
signals parameterized for this must be time stamped throughout the system with
a specified accuracy (e.g. 10 ms) when there is a change. This means that if 2
encoders of two stations on different PROFIBUS-DP master systems are being
used at the same time, the time stamps of these signal changes can only differ
by the specified accuracy (in this case 10 ms).
Time synchronization
Time synchronization ensures that all the clocks in a system have the same time.
This is achieved by a master clock in a configured cycle issuing the time to all
the other components in the automation system that have a clock. The
components use the time issued to set their own clocks.
Ungrounded
Without a conductive connection to ³ ground.
Update
You should update the interface module IM 153-2 to the latest firmware version
following (compatible) function-related expansions or performance
improvements.
Version
All products with an order number have a release number; this indicates the
version of the product. The product version is incremented with each upwardly
compatible function enhancement, production-related modification (use of new
components) or bug-fix.

Further information on redundancy with IM 153-2
You can operate the IM 153-2 redundantly
•
At an SIMATIC S7-400H (e.g. CPU 417-4H)
•
With a GSD file at any DP masters (e.g. S5-115H)
In case of configuration with a GSD file, redundant operation of the IM 153-2
can only be carried out in the DPV0 operating mode. Setting of this operating
mode is carried out differently depending on the configuring tool used.
•
With software redundancy
The optional software "SIMATIC S7 Software Redundancy" is required in
addition to the STEP 7 basic package.
•

On Section 3.7
Further information on the jitter
The maximum jitter amounts to 10 µs if
•
The equidistance cycle of the DP master (pulse control at the PROFIBUS DP)
does not exceed a jitter of 1.3 *s and
•
only the IM 153-2Bx.. is regarded with PROFIBUS DP and I/O bus.
The jitter is not always observed when asynchronous events (e.g. withdrawing and
plugging, diagnostics) occur. It is possible to eliminate the influence of
asynchronous events on the jitter by configuring "Reserve periods".
Due to existing variety the jitter of the periphery (I/O) modules of the ET 200M
cannot be taken into consideration.
Further information on the properties
In case of asynchronous events (e.g. withdrawing and plugging, diagnostics and
interrupts of periphery (I/O) modules) the reaction of the of the IM 153-2 to the I/O
units can fail or a larger jitter can occur during a cycle.
Further information on the properties
If the ET 200M is operated at a non-S7 DP master, stable equidistant operation is
only ensured if the DP master fulfils the following requirements:
•
The DP master has to be configured with the "delayed" interrupt mode.
The data transfer is then not interrupted. A diagnostic message is inserted into
the next free time window for acyclic jobs.
•
The DP master has to operate with the repeat strategy "retry next cycle“.
The repetition of a message is then not carried out in the same cycle in which
the fault occurred, but rather in the following cycle.
•
The DP master has to support the modified Target Rotation Time process (in
accordance with IEC 61784-1:2002 Ed1 CP 3/1) for further active stations.
Otherwise asynchronous events (such as hardware interrupts, diagnostics) can
cause cycle failures or a larger jitter. These failures / larger jitters can always be
expected when the asynchronous events occur very often

Information on channel-specific diagnosis
Errors which affect all the channels of a module (e.g. supply voltage of the module
failed) are only mapped to Channel 0 in the channel-specific diagnostics.
This reduces the number of channel-specific diagnostics and prevents a
"diagnostic overflow".
