The CM CANopen enables you to connect any CANopen or CAN 2.0A devices to your SIMATIC S7-1200 PLC. The module plugs into your S7-1200 and acts as a bridge between the CANopen/CAN devices and the micro PLC. This allows you to choose from a wider range of automation products when designing your system.

CANopen and CAN 2.0A support

Simply attach the CM CANopen expansion module to the SIMATIC S7-1200 PLC. Any device running the CANopen protocol or any custom CAN 2.0A based protocol can then be connected.

Once attached to the S7-1200, you then set up the CM CANopen module from within TIA Portal®. Your CANopen network configuration can then be made in the accompanying CM CANopen Configuration Studio.

The CM CANopen module can be configured to be either a Master or Slave from TIA Portal. No programming is needed to create the configuration.
