Note
A note contain important information on the product described in the documentation, on the
handling of the product and on the section of the documentation to which particular attention
should be paid.
Note on IT security
Siemens offers IT security mechanisms for its automation and drive product portfolio in order
to support the safe operation of the plant/machine. We recommend that you inform yourself
regularly on the IT security developments regarding your products. You can find information
on this on the Internet (http://support.automation.siemens.com).
You can register for a product-specific newsletter here.
For the safe operation of a plant/machine, however, it is also necessary to integrate the
automation components into an overall IT security concept for the entire plant/machine,
which corresponds to the state-of-the-art IT technology. You can find information on this on
the Internet (http://www.siemens.com/industrialsecurity).
Products used from other manufacturers should also be taken into account here.

(electromagnetic compatibility).

CM PtP communication module (6ES7137-6AA00-0BA0)
Manual, 01/2013, A5E03790792-01 19
Parameters/address space 4
4.1 Parameter assignment
Introduction
You configure and assign the parameters of the communication module with STEP 7
(TIA Portal V12 or later) or with STEP 7 with integration of a GSD file.
Additional information
The device manual of the communication module is supplemented by the function manual
CM PtP - Configurations for point-to-point connections
(http://support.automation.siemens.com/WW/view/en/59057093) and the TIA Portal
information system.
There you will find information on the following topics:
● Operating modes
● Receive buffer
● Data flow control
● Transmission integrity
● Data transmission - protocol specific
● Programming/configuring in STEP 7 (TIA Portal)
● Module-specific instructions
● Diagnostics
4.2 Reaction to CPU STOP
Ongoing transmissions are aborted when the higher-level control (CPU) goes to STOP.
Frames in the receive buffer are retained. With a corresponding configuration in the
properties dialog of the communication module, you can automatically clear the receive
buffer on the communication module during CPU startup.

Parameters/address space
4.3 Address space
CM PtP communication module (6ES7137-6AA00-0BA0)
20 Manual, 01/2013, A5E03790792-01
4.3 Address space
Address space of the communication module
The input addresses of the communications module total 8 bytes. The input addresses are
automatically assigned for each communications module when you specify the device
configuration in STEP 7 (TIA Portal). Output addresses are not required.
Hardware identification (not freely configurable)
The hardware identification (HW ID) is automatically assigned for each communications
module when you specify the device configuration in STEP 7 (TIA Portal).
The hardware ID is issued along with the diagnostic messages to localize the module. In
addition, the HW identification is required for S7-1500 at the communication instructions in
order to identify the communication module. For S7-300/400, the communication module is
identified by the start address of the input data.
