13.2 CANopen Data Transfer Settings
CANopen is the networking concept based on the international standard CAN. CANopen is
defined as a uniform application layer by the DS301 specifications of the CiA (CAN in
automation).
13.3 CANopen Cable Arrangement
The CANopen interface uses a DSUB 9-pin plug connector. The plug is assigned with the
CAN_H, CAN_L and CAN_GND connections. CAN_H and CAN_L are two physically
different bus levels. CAN_GND is the common reference potential.
