Ask a question

The Ixxat CM CANopen is a powerful and easy-to-configure gateway for integrating CANopen nodes into a SIMATIC S7-1200 environment. In addition, the module connects directly to the S7-1200 PLC. This creates a seamless interface between CANopen or CAN nodes and the controller. Furthermore, the S7-1200 can work with many more automation products. This provides additional flexibility when designing industrial systems.

The module can function as both a master and a slave, depending on the application. In master mode, the CM CANopen manages the entire CANopen network. The module initializes nodes and continuously monitors the network status. Additionally, the gateway performs configurations to ensure stable communication. In slave configurations, however, the module ensures a smooth connection with the S7-1200 PLC. This ensures reliable and efficient data exchange.

Integration within the SIMATIC® environment is performed using TIA Portal®. This allows the CM CANopen to integrate seamlessly into existing automation projects. The CANopen network is then configured using the “CM CANopen Configuration Studio”. This Windows® tool from Ixxat is included as standard. With this software, the user configures CANopen nodes and communication parameters. In addition, PDOs can be easily assigned. This ensures that the configuration is carried out clearly and efficiently.

Alternatively, the CM CANopen can also function as a standard CAN 2.0A node. This makes the module suitable for a wide range of industrial CAN applications. In short, the CM CANopen offers a flexible solution for industrial communication and automation.

CANopen for S7-1200

CANopen support

Simply attach the CM CANopen expansion module to the SIMATIC® S7-1200 PLC. Any device running the CANopen protocol can then be connected. The CM CANopen module can be used from within TIA Portal® and can be configured to be either a Master or Slave from TIA Portal®. No programming is needed to create the configuration.

CANopen configuration and TIA Portal® integration

The seamless integration into the SIMATIC® world is one of the most essential requirements when extending of the SIMATIC® automation system with networked fieldbus equipment that is not based on either PROFIBUS or PROFINET. HMS has addressed this need enabling a seamless integration of the CM CANopen module into TIA Portal®. Configuration of the connected CANopen network is intuitively performed with the included CM CANopen Configuration Studio.

Once the configuration is finalized, the CANopen network configuration is downloaded into the CM CANopen module and localz stored in non-volatile memory. If one of the slave devices in the connected CANopen network has to be replaced, configuration data for this device will be downloaded automatically by the CM CANopen module once the device is reattached, significantly reducing down-times in high availability applications.

Transparent CAN CC (Classic CAN 2.0) mode

With this functionality, the CM CANopen module allows transmission of any CAN frame from the PLC regardless of the overlaying CAN protocol and is capable of receiving a number of pre-defined CAN frames from the CAN network.

  • Possibility to implement any custom CAN based protocol which in interpreted/generated by the PLC
  • Special PLC function block available from HMS for easy integration in to TIA Portal®
  • CAN frames pass transparently through the CM CANopen module
  • Ability to transmit and receive CAN frames inside TIA Portal®
  • Supports only the CAN 2.0A standard (11-bit CAN identifiers)
  • CANopen functionality is disabled when the transparent CAN mode is used

FAQ

  • Is there a CAN terminating resistor built into the CM CANopen?

    There is no built-in CAN terminating resistor, and there is no provision for one. If necessary, a terminating resistor can be installed across the CAN connections. Alternatively, we offer the PCAN-Adapter D-Sub to Screw Terminals as an accessory.
