Preface
Purpose of the documentation
This manual supplements the S7-1500/ET 200MP
(https://support.industry.siemens.com/cs/ww/en/view/59191792) system manual.
Functions that relate in general to the systems are described in this system manual.
The information provided in this manual and in the system/function manuals supports you in
commissioning the systems.
Conventions
The term "CPU" is used in this manual both for the CPUs of the S7-1500 automation system
and for interface modules of the ET 200MP distributed I/O system.
Please also observe notes marked as follows:
Note
A note contains
important information on the product described in the documentation, on
the handling of the product or on the section of the documentation to which particular
attention should be paid.
Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed visit (https://www.siemens.com/industrialsecurity).

3.3 Connecting a module with a connection module
Component for connecting
To connect sensors, you need 2 connection modules per module. The connection modules
are connected to the module with pre-assembled connecting cables.
You can find additional information on the components of the SIMATIC TOP connect system
cabling, e.g. for connecting connection modules, in the equipment manual SIMATIC TOP
connect for S7-1500 and ET 200MP
(https://support.industry.siemens.com/cs/ww/en/view/95924607).
Note
Common supply
If you use the listed SIMATIC TO
P connect connection modules, then all 32 channels of a
connection module have
a common supply. This means that 2 groups of 16 channels each
are supplied by common potential.
You can find the required components in the tables below.
