8.2 Control Area Network (CAN Bus)
Why CAN?
●
Reduced wiring
●
Future proof – ease of adding options
●
CAN open specification allows multiple manufactures to be sourced
●
Short reaction times for priority commands
●
Fault analysis built into architecture – ability to recover
●
Simplicity of interface (mechanical and electrical)
CAN Features
●
Uses line topology: participants are connected parallel via bus (DEK)
●
Data transmission speed of 500 Kbit/sec (DEK)
●
Data exchange: Each device (Node) may send data if bus is not occupied
●
COB´s are read by all nodes but any action is only performed by the addressed Node(s)
●
A COB-ID (COB identifier) determines the receiving Nodes address and the priority of the
message
