Siemens CMDP Module

The CM DP module operates as a DP-V1 master and processes the data transfer completely independently. It also supports the acyclic standard services, including interrupt handling. During normal operation, it is also possible to activate or deactivate DP slaves. Among other things, this allows the step-by-step commissioning of subprocesses. A diagnostic repeater allows the line to be diagnosed during operation, enabling line faults to be detected at an early stage. The CM DP module supports operation with a diagnostic repeater (including activation of topology identification on the diagnostic repeater).

It is possible to connect PROFIBUS slaves, e.g. CM 1242-5 as a DP slave, DP slaves of the ET 200 distributed I/O, etc.

This creates the possibility for the ET 200SP CPU of setting up a further distributed I/O in addition to the network of the integrated PROFINET interface.

The CM DP module operates as a DP slave and processes the data transfer completely independently. It thus connects the ET 200SP CPU as intelligent slave to a higher-level DP master.

This creates the possibility for the ET 200SP CPU being connected to an existing PROFIBUS DP network as intelligent slave in addition to the network of the integrated PROFINET interface.
