CANopen: Communication in Automation Technology

What is CANopen?

CANopen is an internationally standardized bus protocol based on the seven-layer ISO/OSI reference model. It was developed by the CIA (CAN-in-Automation user and manufacturer association) and has been standardized as the European standard EN 50325-4 since the end of 2002.
CANopen uses layer 1 and 2 of the CAN standard originally developed for use in cars (ISO 11898-2) as a transmission technology. The bus system enables each device to send messages (multimaster capability). Messages on the bus are received by each bus device (broadcast communication). Each bus device then decides whether or not these messages are processed based on its local intelligence.
