CAN User Benefits (cont.)
q CAN means real-time
maximum data rate is 1 MBit/s @ 40m bus length
(still about 40 kBit/s @ 1000m bus length)
Short message length (0 to 8 data bytes / message)
(Larger data can be split up into several messages)
Low latency between transmission request and actual start of transmission
Bus access handled via CSMA/CD w/ AMP method (message with the
highest priority wins arbitration without losing any time)
q CAN is flexible
CAN allows Multi-Master Operation
(every CAN node is able to access the bus individually)
CAN Nodes can easily be connected / disconnected
(i.e. plug & play)
Number of nodes not limited by the protocol
