15-1 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 4.02 of CANopen (CiA DS301) is
standardized as EN50325-4. The CANopen specifications cover the application layer and
communication profile (CiA DS301), as well as a framework for programmable devices (CiA DS302),
recommendations for cables and connectors (CiA DS303-1), SI units and prefix representations
(CiA DS303-2).
