Chapter 15 CANopen Overview│CP200015-315-1 CANopen OverviewCANopen ProtocolCANopen is a CAN-based higher layer protocol, and was designed for motion-orientedmachine control networks, such as handling systems. Version 4.02 of CANopen (CiA DS301) isstandardized as EN50325-4. The CANopen specifications cover application layer andcommunication 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).Device Profile CiADSP-401Device Profile CiADSP-404Device Profile CiADSP-XXXOSI Layer 7Application Communication Profile CiA DS-301CAN Controller CAN 2.0AOSI Layer 2Data Link LayerISO 11898OSI Layer 1Physical Layer + -+ -CAN busRJ-45 Pin Definition8~1 8~1PIN Signal Description1 CAN_H CAN_H bus line (dominant high)2 CAN_L CAN_L bus line (dominant low)3 CAN_GND Ground / 0V /V-6 CAN_GND Ground / 0V /V-Plug Socket
