Modular Sensor Interface M 60
35 / 104
9 CAN Bus
M 60 has 2 CAN buses. Both buses are fully configurable.
– Baudrate (125 kbit to 1 Mbit)
– 11 bit or 29 bit identifiers
– Input configuration: Read messages from CAN bus and convert to M 60 measure-
ment/display variables. CAN bus supports row counter configuration.
– Output configuration: Write M 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 M 60 bus data rate in ‘Properties’ menu.
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
