Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Agreement: In the following, the designation IM 153-x is used in the operating instructions,
except if a description refers directly to a special version of the IM 153-x.
A variant of the IM 153-1 as well as the IM 153-2 is additionally available as a module for use
in extended environmental conditions ("Outdoor"). You can find the climatic and mechanical
ambient conditions under which you can use this IM 153-1 / -2 in the reference manual "S7-
300 automation system, module specifications
(http://support.automation.siemens.com/WW/view/en/8859629)".
For the new revision of the IM 153-x, we reserve the right to enclose a product information
with current information for the corresponding IM 153-x Interface Module or the operating
instructions.
You can also find this product information on the Internet
(http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo2&aktprim=99&lang
=en). Look for "IM 153-2" there, for example.

1.1 What Are Distributed I/O Devices
Area of application
When a system is set up, it is common for the inputs to and outputs from the process to be
incorporated centrally in the automation system.
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 control CPU is located at a central location
•The I/O devices (inputs and outputs) operate locally on a distributed basis.
•the powerful PROFIBUS DP with high data transmission speed ensures that the control CPU
and the I/O devices communicate smoothly.
•PROFINET IO
1.2 What is PROFIBUS DP?
What is PROFIBUS DP?
PROFIBUS DP is an open bus system in accordance with the standard
IEC 61784-1:2002 Ed1 CP 3/1 with the transmission protocol "DP" (DP is the abbreviation of
the German term "dezentrale Peripherie" (distributed I/O).
Physically, the PROFIBUS DP is either an electric network based on a shielded two-wire line
(RS 485) or an optical network based on a fiber-optic cable (FOC).
The transmission protocol "DP enables a fast, cyclic data exchange between the control CPU
and the distributed I/Os.
What are the DP master and DP slaves?
The DP master is the connecting link between the control CPU and the distributed I/Os. The
DP master exchanges the data via the PROFIBUS DP with the distributed I/Os and monitors the
PROFIBUS DP.
The distributed I/Os (= DP slaves) prepare the data of the encoder and the actuators on site in
such a way that they can be transmitted via the PROFIBUS DP to the control CPU.

Which devices can be connected to PROFIBUS DP?
The most varied devices can be connected as DP masters or DP slaves to the PROFIBUS DP, the
only proviso is that they behave in accordance with the standard
IEC 61784-1:2002 Ed1 CP 3/1. Among others, devices of the following product families can
be used:
•SIMATIC S7 / M7 / C7
•SIMATIC S5
•SIMATIC PD / PC
•SIMATIC HMI (operator panel (OP), operator station (OS), and text display (TD) operator
control and monitoring devices)
•Devices from other manufacturers
Structure of a PROFIBUS DP network
The figure below illustrates a typical PROFIBUS DP network structure. The DP masters are
integrated in the respective device, e.g. if the S7-400 has a PROFIBUS DP interface, the
master connection IM 308-C is connected with an S5-115U. The DP slaves are the distributed
I/O devices that are linked with the DP masters via the PROFIBUS DP.

Operating Instructions, 04/2022, EWA-4NEB7806006-09 13
1.3 What is PROFINET IO?
Definition
PROFINET IO is an open transmission system with real-time functionality defined in
accordance with the PROFINET standard. This standard defines a manufacturer-independent
communication, automation and engineering model.
Accessories for wiring the PROFINET components are available in industrial quality.
•PROFINET discards the hierarchical PROFIBUS master/slave concept and deploys a
provider/consumer principle instead. The modules of an I/O device that will be subscribed
to by an IO controller are defined within the engineering phase.
•The quantity framework is extended in accordance with the options offered on
PROFINET IO. Parameter limits are not exceeded during configuration.
•The transmission rate is 100 Mbps.
•The configuration interface for users is generally the same as that on PROFIBUS DP (the
system is configured in STEP 7 > HW CONFIG).
Topology of a PROFINET IO network
The figure below shows a typical PROFINET IO network topology. Existing PROFIBUS slaves
can be integrated using an IE/PB link.

1.4 ET 200M distributed I/O device
Definition
The distributed IO device, ET 200M, is a modular DP slave with an IP 20 degree of protection.
The ET 200M has the configuration technology of the S7-300 automation system and
consists of an IM 153-x and I/O modules of the S7-300.
ET 200M supports communication with:
•all DP masters compliant with IEC 61784-1:2002 Ed1 CP 3/1
•all IO controllers compliant with IEC 61158
Configuration of the ET 200M (example)
①
Power supply module PS 307
②
Interface module IM 153-x
③
up to 12 I/O modules (SM / FM / CP)

In the STEP 7 module catalog or in the GSD file you will find a list of the modules that you can
use in the ET 200M.

"SIMATIC S7-DP-Slave"
The ET 200M distributed I/O system is a constituent part of the SIMATIC S7 automation
system.
In other words, STEP 7 provides support when configuring, assigning parameters to and
programming the ET 200M in the DP master system as well as for the commissioning and
diagnostics. Special services and functions of the IM 153-2 (e.g. configurable FM) can be used
to their full extent only in the SIMATIC S7 / PCS 7.
If you use the ET 200M on a DP standard master (e.g. S5-95U), the configuration tool will also
provide support with the GSD file, but, for example, you must pay attention to the technical
data (project data) of the DP master (possible parameter assignment and diagnostics
message frame lengths etc.).
The PROFIBUS standard IEC 61784-1:2002 Ed1 CP 3/1 also includes the DPV1-mode. You can
use this mode only if you integrated the GSD-file Revision ≥3.
The GSD-file Revision 2 remains available and hence the compatibility with earlier versions of
the IM 153-x is assured.
Components
A series of components are provided for the configuration and commissioning of the ET
200M. The most important components and their functions are listed in the following table:

1.5 IM 153-x: Variants and properties
Brief overview of the different IM 153-x
The IM 153-x contains interface modules for the signal modules (SM), function modules (FM)
and communication processors (CP).
You have an RS 485 interface (IM 153-2 alternatively also with FOC interface) and offer a
graded functional scope. The respective variants of the interface module IM 153-2 with
RS 485 or FOC interface have the same functionalities.
From the IM 153-1 and IM 153-2 there is also a variant for use in other operating conditions
(outdoors).
Properties and functions
The following table provides a detailed overview of the properties and functions of the
different IM 153-x and their current versions.
You will find the comparison with the respective predecessor versions that are not listed in
this table in the appendix "Compatibilities between the IM 153-x (Page 241)".
