OverviewSIMATIC S7-1200 CM CANopen

An interface module is available for operating the S7-1200 on CANopen. It can be used together with system and IO components of the S7-1200 automation system.

CiA and CANopen are registered Community Trademarks of CAN in Automation e.V.


CANopen is a widely used industrial bus system and can be used for a variety of different applications. The module allows simple and cost-effective connection of CANopen applications to SIMATIC.

  • Control of hydraulic valves/axes in vehicles
  • Control of motors in packaging machines or conveyors
  • Capturing of angular encoder positions in wind turbines
  • Capturing of control devices on machines, e.g. joysticks
  • Capturing the measured data of path encoders, inclinometers or angular encoders, e.g. for tower cranes and gantry cranes

The CM CANopen module has the following properties:

  • Interface module for CANopen (master/slave) for SIMATIC S7-1200
  • Connection of up to 16 CANopen slave stations in the master mode
  • 256 bytes of input data and 256 bytes of output data per module
  • Connection of up to 3 modules per CPU
  • 3 LEDs for module, network and I/O status diagnostics
  • Possible integration of the module into the hardware catalog of the TIA Portal configuration suite
  • Supports Transparent CAN 2.0A for processing customer-specific protocols
  • CANopen implementation according to communication profiles CiA 301 Rev. 4.2 and CiA 302 Rev. 4.1 (master)
