The »fpControl CAN Interface – SAE J1939« (fpControl CI-SAE J1939) manages the communication between the »fpCAN« and an external SAE J1939-CAN-BUS.
In order to monitor the level of the diesel fuel in the tank, you can integrate a tank sensor with SAE J1939-CAN interface in the fpCAN. The tank sensor sends the filling level of the diesel tank in percent on the CAN bus.
With the J1939 CAN interface, you can start and stop the generator via a CAN message. In this example you will activate the automatic start mode using the proprietary PGN PROPA00 (PGN 61184) and the RPC ID 0x0012. After this you will start the generator using PROPA00 as well. But in this case using the RPC ID 0x009c.
If there is more than one J1939 CAN interface in the Fischer Panda CAN bus, each interface needs a different bus address. This is achieved by “Address Claiming”, in which the bus sharing units negotiate addresses with each other.
In some applications, it may be necessary for a CAN interface to have a fixed static address that never changes.
How does an RPC request for the serial number of a bus sharing unit work in practice with the Fischer Panda J1939 CAN Bus?
Contact numbers, assignments and wire colors of the RJ45 connector for the Fischer Panda CAN-Bus.
With the adapter, you can establish a connection between the 9 pin D-SUB socket of a CAN‑USB adapter and an RJ45 plug of the Fischer Panda CAN bus. You need the adapter to connect the Fischer Panda CAN bus to a PC using a CAN-USB adapter.
