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

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.
