Ixxat CANopen Master/Slave module for SIMATIC S7-1200 PLC 21620

Integrating CANopen networks into Siemens SIMATIC S7-1200 PLC systems often requires additional hardware and complex configuration. The Ixxat CANopen module (21620) solves this by providing a direct, backplane-mounted solution that enables the S7-1200 to act as a CANopen master or slave. It handles the CANopen protocol stack internally, allowing the PLC to exchange process data with CANopen devices through simple I/O mapping in the TIA Portal.

Who is it for

Automation engineers and system integrators who need to connect CANopen devices—such as drives, encoders, or I/O blocks—to a Siemens S7-1200 PLC. It is suitable for both new installations and retrofits where CANopen fieldbus connectivity is required.

Tips

Ensure your TIA Portal version is V13 SP1 or later to use the configuration tools. When designing a CANopen network, plan the bus length and termination according to the selected bit rate. The module's galvanic isolation helps protect the PLC from ground loops and voltage differences on the CAN bus.
