Plug-in CANopen module for SIMATIC® S7-1200 systems

Ixxat CM CANopen

Item number 021620-B

The Ixxat CM CANopen is a compact interface module designed for the integration of CANopen or CAN 2.0A devices with SIMATIC S7-1200 automation systems. It offers a cost-efficient solution to achieve PROFINET connectivity for CANopen-based field devices, offering full integration into the Siemens TIA Portal and configuration tool support.

Features and benefits

  • CANopen connectivity for SIMATIC S7-1200 systems

    As a CANopen commander/responder (master/slave) module, it connects any CANopen or CAN 2.0A field device to a SIMATIC S7-1200 PLC, acting as a bridge between the devices.

  • Cost-effective system expansion

    Supports up to three CM CANopen modules per PLC and up to 16 CANopen responder (slave) devices in commander (master) mode, enabling scalable system expansion without significant cost increase.

  • Simplified configuration

    User-friendly configuration thanks to integration into the hardware catalogue of the TIA Portal configuration environment.

  • Support for transparent CAN 2.0A protocols

    Supports transparent CAN 2.0A for custom protocol implementation. Ready-made PLC function blocks are available in the TIA portal for fast integration​.

  • Flexible mode operation

    Can be easily configured as either a commander (master) or responder (slave) module, providing flexibility with no additional programming required.

  • Diagnostic clarity

    Integrated LEDs provide comprehensive diagnostic information on module network and I/O status for easy troubleshooting.

  • Overvoltage protection

    Galvanic isolation safeguards against overvoltage and protects from potential electrical damage.
