CANopen was developed by the members of the international user and manufacturer association CAN in Automation (CiA). The CANopen application layer defines different communication services and protocols (e.g. process- and service data) as welll as a network management.
CANopen is mainly used as an embedded network in machines, but also as a general industrial communication system. It is based on the international norm ISO 11898-1 (CAN-Protocol) and ISO 11898-2 (fast physical connection layer). The CANopen application layer is classified by the CENELEC as EN 50325-4.
The introduction in CANopen describes the basic communication mechanisms and usage of the CAN identifiers.
