The CAN Protocol Tour
The CAN Protocol Tour provides a great introduction to the fundamentals of CAN as it is used in automotive design, industrial automation controls, and many, many more applications.
About CAN: A Flexible and Powerful Protocol
The CAN protocol is an ISO standard (ISO 11898) for serial data communication. The protocol was developed aiming at automotive applications. Today CAN has gained widespread use and is used in industrial automation as well as in automotives and mobile machines.
Distributed Control Systems
The CAN protocol is a good basis when designing Distributed Control Systems. The CAN arbitration method ensures that each CAN node just has to deal with messages that are relevant for that node.
A Distributed Control System can be described as a system where the processor capacity is distributed among all nodes in a system. The opposite can be described as a system with a central processor and local I/O-units.
