CANopen® Interfaces for SIMATIC®
Industrial Automation Systems


The CANopen modules by HMS enable system integrators to easily and inexpensively integrate CANopen field devices with SIMATIC industrial automation equipment. The modules allow interaction between PROFIBUS or PROFINET controllers – such as the S7-1200 or ET200S device series – with CAN/CANopen fieldbus devices (gateways).

  • Networking of medical devices
  • and more...

The 1 SI CANopen for the SIMATIC ET200®S modular I/O system and the CM CANopen module for the SIMATIC S7-1200® basic controller implement the HMS CANopen master technology in a compact format fully integrated with the SIMATIC hardware. They allow to directly extend SIMATIC automation solutions with CAN or CANopen based equipment making more expensive and space demanding PROFIBUS or PROFINET to CANopen gateways unnecessary. 

Both modules are supported by optimized and highly intuitive CANopen configuration tools that enable users to quickly generate all required configuration data for the CANopen network.
Due to the support for operation in transparent CAN 2.0A mode, system integrators have the possibility to implement any custom CAN based fieldbus protocol.
