Canopen is a communication protocol based on CAN, which is used to connect complex or time-critical machines and systems in automation equipment. Canopen not only regulates the lower communication level, but also the command structure of various instrument types.

Pros:

        1、The technology is mature and robust, making it ideal for circuit topologies with extremely short stubs and twisted pair；

        2、A network can connect up to 127 nodes/devices and support multi-axis applications；

        3、High-speed transmission, Data transfer rate up to 1 Mbit per second；

        4、Standard protocol for all types of devices.
