E.1 Overview

E.1.1 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).
