Introduction

The CM PtP communications module is used with a BaseUnit of type A0 (article number
6ES7193-6BPx0-0xA0).
You connect the input and output signals to the BaseUnit of the communications module.
The supply voltage feed on the light-colored BaseUnit BU...D of the associated potential
group supplies the module.
BaseUnit
The BaseUnit is not included in the scope of delivery of the module and must be ordered
separately.
You will find an overview of the BaseUnits you can use with the communications module in
Product information on the documentation of the ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/73021864).
You can find information about selecting a suitable BaseUnit in the ET 200SP Distributed I/O
system (http://support.automation.siemens.com/WW/view/en/58649293) system manual and
ET 200SP BaseUnits
(http://support.automation.siemens.com/WW/view/en/58532597/133300) manual.
You can find information on wiring the BaseUnit, connecting cable shields, etc. in the Wiring
section of the ET 200SP Distributed I/O system
(http://support.automation.siemens.com/WW/view/en/73021864) system manual.
Supply voltage L+/M
With a light-colored BaseUnit, you connect the supply voltage to the L+ and M terminals. With
a dark BaseUnit, the supply voltage of the left-hand module is used. An internal protective
circuit protects the communications module from polarity reversal of the supply voltage. The
communications module monitors the connection of the supply voltage.
