CAN - Controller Area Network
Serial data bus for real-time application
- Messages are short (controlled length)
- opportunities to insert a new message come often
- Messages have assignable priority
- most critical messages dominate during heavy load
Low probability of an undetected error
- 4.7 x 10-11 x message error rate
- For a message error rate of 25/sec: 1 undetected error per 10,000 hours operation
