General

CANopen is a higher layer protocol built on top of the CAN bus. It is widely used in various industrial application fields, e.g. off-road vehicles, maritime electronics, or railway applications.

Refer to CAN in Automation (CiA) for more information about CANopen.

Interpretation

CANtrace supports the CANopen protocol. When analyzing a CANopen network, interpretation can be easily enabled in the trace window by right-clicking on the trace area, toggling it on from the toolbar or selecting Interpretation > CANopen from the menu.

The NMT, EMCY, SDO, and other standard messages will be interpreted into a human-readable text format automatically.
