CANopen is a communication protocol stack and device profile specification for embedded systems used in automation. In terms of the OSI model, CANopen implements the layers above and including the network layer.

Need a simple, practical intro to CANopen? In this guide we introduce the CANopen protocol basics incl. the object dictionary, services, SDO, PDO and master/slave nodes. Note: CANopen can seem complex - so this tutorial is a visual intro in layman's terms. Read on below to fully understand CANopen.

CANopen unburdens the developer from dealing with CAN hardware-specific details such as bit timing and acceptance filtering. It provides standardized communication objects (COB) for time-critical processes, configuration as well as network management data.

This table highlights the fundamental differences between CAN and CANopen, with CAN providing the lower-level communication framework, while CANopen builds on top of CAN to standardize higher-level communication and device interoperability.

CANopen is a CAN-based communication system. It comprises higher-layer protocols and profile specifications. CANopen has been developed as a standardized embedded network with highly flexible configuration capabilities. It was designed originally for motion-oriented machine control systems, such as handling systems. Today it is used in various ...

The Controller Area Network (CAN) bus was developed in 1983 by Bosch and Intel as a fieldbus for real-time-capable, low-cost data transmission in vehicles.

CANopen is a CAN-based higher layer protocol. It is developed as a standardized embedded network with highly flexible configuration capabilities. CANopen is designed for motion-oriented machine control networks, such as handling systems.
