CANOpen
CANopen is a communication protocol and device profile specification for embedded automation based on the Controller Area Network (CAN). Developed and maintained by CAN in Automation (CiA), it provides a robust, scalable framework for connecting devices in industrial environments, covering real-time I/O, control, and diagnostics. CANopen runs on the CAN physical layer (ISO 11898) and supports multi‑master networks.
At the core of CANopen is the object dictionary, a standardized map of all device parameters. Communication
CANopen defines standard device profiles to promote interoperability among devices from different manufacturers. The most common
In operation, networks may be configured in a boot sequence through NMT, with devices moving from pre-operational
Applications of CANopen span industrial automation, robotics, packaging, medical equipment, building automation, and mobile machinery. Since
