9 CAN Bus
C 60 has two fully configurable CAN buses.
– Baudrate (125 kBit ... 1 MBit)
– 11 Bit or 29 Bit identifiers
– Input configuration: Read messages from CAN bus and convert to C 60 measure-
ment/display variables. CAN bus supports row counter configuration.
– Output configuration: Write C 60 measurement variables to CAN messages, output
frequency and row counter are configurable, CAN gateway functionality (transfer from
one bus to the other).
9.1 CAN bus trivia
CAN message
– 11 Bit (standard) or 29 Bit (extended) identifier
– Up to 8 bytes of data payload
CAN bus
– Needs termination resistors (120 Ohm) in wiring harness
– All devices connected to the bus must use identical data rate
Configuration of C 60 bus data rate by double click on the CAN bus
in project tree (1 MBaud, 500 kBit, 250 kBit, 125 kBit)
Row counter concept
– Re-use (multiplex) of message identifiers
– One byte of message contains row counter
– 7 bytes payload remaining
– Position of row counter is configurable
