CANopen specifications
CANopen specifications
Description
CANopen is a CAN-based communication system. It is internationally standardized in EN 50325-4 and supports many profile specifications (CiA 4XX series). CANopen has been developed as a standardized embedded network approach with flexible configuration capabilities. It has been designed originally for motion-oriented machine control systems, such as handling systems. Today, it is used in various application fields such as medical equipment, off-road vehicles, or building automation.
CANopen unburdens the developer from dealing with CAN hardware-specific details such as bit timing and acceptance filtering. It provides standardized communication objects (COB) for time-critical processes, configuration as well as network management.
With the availability of CAN FD as an improved CAN data link layer, CANopen has been enhanced to make use of the advantages offered by CAN FD. The resulting CANopen FD is available in CiA 1301. The classic CANopen (specified in CiA 301), is refered to as CANopen CC.
Many of the CANopen specifications are available free of charge. But there are also CANopen documents, which need to be subscribed. Of course, CiA members have free-of-charge access to all these specifications.
