CANopen has been developed by the members of the international user and producer assosiation CAN in Automation (CiA). The CANopen application layer defines different communication services and protocols (e. g. process and service data) as well as a network management.


CANopen is mainly used in machines as an embedded network but also as a general industrial communication system. It is based on the international standards ISO 11898-1 (CAN protocol) and ISO 11898-2 (fast physical transmission layer). The CANopen application layer has been defined as standard EN 50325-4 by CENELEC.
