Hardware Overview
8.4 CAN Bus
A Controller Area Network (CAN) bus is an industrial standard bus used to establish
communication between all the sensors, the BMPC/2 wiring box, and the BMPC/2.
8.4.1 CAN Bus Structure
The BMPC/2 control unit is designed as a CAN bus master. This means all communica-
tion on the bus is controlled and monitored from this master.
All sensors and the BMPC/2 wiring box are designed as CAN bus slaves. The BMPC/2
wiring box is also able to fullfill CAN bus master functions in case the BMPC/2 control
unit is not functioning.
