CANopen is a CAN-based application layer protocol. It was developed as a standardized embedded network with highly flexible configuration capabilities. CANopen was designed for motion-oriented machine control networks, such as handling systems. By now it is used in many various fields, such as medical equipment, off-road vehicles, maritime electronics, public transportation, building automation, etc.
The CANopen specifications cover application layer and communication profile, as well as a framework for programmable devices, recommendations for cables, connectors, SI units, and prefix representations. The application-layer as well as the CAN-based profiles are implemented in software.
CANopen features

- 10k,20k,50k,125k,250k,500k,800k,1M bps baud rate
- The bus length is from 25m(1M bps) to 5Km(10K bps)
- Easy access to all device parameters.
- Device synchronization.
- Cyclic and event-driven data transfer.
- Up to 128 nodes can be participated in the same CAN network.
- High transmission speed.
- Support Guarding and Heartbeat protection mechanism

CANopen remote I/O unit series
CAN-8x23 series are specially designed for the slave device of CANopen protocol with 1/2/4 I/O slot. There are various modules can be chosen to use. Also, these products support Hot-swap function for maintaining conveniently.
CANopen Gateway series
The Modbus TCP/RTU and DCON protocol gateways are ready for users. The series can be used to integrate different protocol system. Users also easily update their old system to the CANopen system with the series. They are I-7231D, I-7232D, GW-7433D.
CANopen master series
CANopen master series are I-87123 for PACs and PISO-CPM100 for PC based. In the series, there is CANopen master kernel inside. So, they can be used in high performance system. For economical solution, we provide the PISO-CAN card with the CANopen master lib.
