CANbus is a serial communication protocol originally developed for communication in vehicles. Its high reliability, easy installation and scalability are the reasons why it's often used in industry.
The application layer of CANbus includes several incompatible standards (CANbus, CANopen, DeviceNet, etc.). Devices relying on these standards can't communicate with each other, but use the same cables, connectors, repeaters, terminating resistors, testers, etc. In our online Store, you'll find products for building CANbus, CANopen and DeviceNet networks, and diagnostic tools for measuring and repairing them.
