8. CANbus functions
The HMCflex supports these CANbus functions according to SAE J1939.
All measured values and fault messages of the HMCflex are output on the CANbus. HMCflex behaves
similar to an ECU with source address 0.
The measured values are thus compatible with many standard CANbus display devices.
The compatibleehb devices are, amongst other, CANcor, CANflex, CANarmatur, CANinfo and
CANmonitor.
