Siemens SIPLUSCM1241 Communication Module

For interfacing to third-party systems with simple transmission protocols, e.g. protocols with start and end characters or with block check characters. The interface handshake signals can be called and controlled via the user program.

For communication according to the Modbus protocol with RTU format:

Master-slave interfacing with SIMATIC S7 as master.

Master-slave interfacing with SIMATIC S7 as slave; message frame traffic from slave to slave not possible.

Instructions for connection of USS protocol drives are especially supported. In this case, drives exchange data over RS485. It is then possible to control these drives, and to read and write parameters.
