CANopen and CANopen FD are higher-layer protocols for CAN and CAN FD (CANbus, Controller Area Network)

CANopen is a network used in many every-day products consisting of multiple microcontrollers that need to communicate with each other. CANopen is based on CAN (Controller Area Network) which is implemented in hardware in microcontrollers of all major chip manufacturers. If you don't know much about CANopen, here is a brief introduction and a historic summary of 30 years of CAN.

The CANopen specification is available for free and can be requested from the CiA organization. The main documents are the CiA Draft Standard 301 and 401 or 1301 for CANopen FD. The additional Draft Standard Proposals are optional, depending on the application implementing CANopen. For a list of current device and application profiles, see the list of profiles at CiA.
