Connecting CANopen devices to the SIMATIC S7-1200 PLC

16 October 2013

The CM CANopen module from HMS Industrial Networks enables users of the SIMATIC S7-1200 PLC to integrate CANopen devices into their automation systems, using the TIA Portal.

The CM CANopen is an extension module for the SIMATIC S7-1200, enabling the PLC to communicate with devices on a CANopen Network. The product has been developed by HMS Industrial Networks and is fully approved by Siemens.

The module plugs into the PLC, working as a translator between nodes on a CANopen Network and the S7-1200. The module fits mechanically into the standard PLC system rack and can be configured to be both Master or Slave. No programming is needed to configure the communication between CANopen and the PLC-users set up how they want the data to flow in the accompanying CM CANopen Configuration Studio software.

It is possible to plug in three modules per PLC, and 16 CANopen slave nodes can be connected to each module (each module supports 256 bytes input and 256 bytes output). There is also support for transparent CAN 2.0A for custom protocol handling, and the module is integratable into the hardware catalogue of the TIA Portal configuration suite.
