HMS 1 SI CANopen module for Simatic ET200S

HMS has extended the functionality of its 1 SI CANopen module for the Simatic ET200S I/O system with the integration of the CAN 2.0A protocol. In addition to the standard CANopen protocol, the HMS 1 SI CANopen module can also be used for transmission/ reception of any CAN 2.0A frame regardless of the overlaying CAN application protocol. The extended functionality maximises usability and flexibility of the CAN gateway. Typical applications include all kinds of machines and automation systems where CAN- or CANopen-enabled devices are used in combination with Siemens PLCs.

The HMS 1 SI CANopen module fits mechanically into the standard ET200S system rack and can be used in combination with all other modules of the ET200S family. The module can be engineered with Step7, allowing easy configuration and diagnostics. Step7 also allows upgrading already existing 1 SI CANopen boards with this new functionality. Using the standard Profibus or Profinet bus coupler of the ET200S, the 1 SI CANopen module can be used along with the large range of Siemens automation and control systems.

HMS supports users of its 1 SI CANopen module with new PLC function blocks which are used to create and analyse CAN 2.0A frames directly in the PLC program. Based on these function blocks, PLC programmers can implement customer-specific CAN application protocols or specific CAN application profiles.
