3. Functional description This communication extracts information from the Electronic Control Module (ECM) of an engine equipped with an ECM module with CANbus interface. The values can be used as display values, alarms/shutdown alarms and values to be transmitted through Modbus.
Communication system All these protocols are based on a CANbus communication system. Except for the MDEC and ADEC communication, all of them are based on the J1939. The MDEC and ADEC protocols are MTU designed protocols based on CANopen. The baud rate is fixed by the engine manufacturer at:...
J1939 measurement table This is the common J1939 measurement overview showing which measurements are available. Note that not all measurements are supported by the individual engines; please refer to the specific engine description. The table shows which values can be displayed in the view screens.

The priority needs to be converted to decimal. Note that the 3 priority bits in this case are displayed in the CAN id (You see 0x c f00400 instead of 0x 0c f00400). In other cases you may read e.g.
