14.1 CANopen Overview
CANopen Protocol
CANopen is a CAN-based higher layer protocol, and was designed for motion-oriented machine
control networks, such as handling systems. Version 4 of CANopen (CiA DS301) is standardized as
EN50325-4. The CANopen specifications cover application layer and communication profile (CiA
DS301), as well as a framework for programmable devices (CiA 302), recommendations for cables
and connectors (CiA 303-1) and SI units and prefix representations (CiA 303-2).
