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 more than 22 chip manufacturers. If you don't know much about CANopen, here is a brief introduction and a historic summary of 15 years of CAN.
The CANopen specification is available for free and can be requested from the CiA. The CiA order form can be used to request the main documents CiA Draft Standard 301 and 401. The additional Draft Standard Proposals are optional, depending on the application implementing CANopen.
