CANopen® Module with Two Serial Interfaces (RS-232, RS-485)

Integration of Two Serial Interfaces Into a CANopen Network

  • Configuration of physical serial interfaces via piggybacks

  • 2x RS-232 or optional 1x RS-232 and 1x RS-485 serial interfaces

  • ARM7 Microcontroller

User Friendly CANopen Module with Solid InRailBus Technology

  • InRailBus technology combines high ease of use and proven reliability

  • CANopen profiles acc. to CiA® specification CiA 301 and CiA DSP 302

Configuration of Serial Interfaces

  • Serial communication parameters can be configured in a flexible range

Serial Interface

Two serial interfaces can be connect to a CAN net. In the standard version the physical layers are realized as two RS-232 interfaces.
Instead of the driver for RS-232 interfaces, the module can be equipped with piggybacks for RS-422, RS-485 or TTY active/passive interfaces.

CAN Interface

The CAN interface is designed according to ISO 11898-2 high-speed layer with electrical isolation and supports bit rates up to 1 Mbit/s. The CANopen-node number and the CAN bit rate can be easily set via coding switches.


The CAN-CBX-COM2 features the possibility to connect the power supply and the CAN bus signals via the InRailBus connector (CAN-CBX-TBUS-connector) integrated in the mounting rail. Individual modules can then be removed from the InRailBus without interrupting the bus signals.

Software Support

The module comes with CANopen firmware according to CiA 301 and CiA DSP 302.
