The »fpControl CAN Interface – SAE J1939« (fpControl CI-SAE J1939) manages the communication between the »fpCAN« and an external SAE J1939-CAN-BUS.
Generators equipped with xControl, iControl2 or fpControl can be connected to the VE.CAN from Victron Energy. The connection is established via the »fpControl CAN Interface – SAE J1939«.
The »Communication Interface CI – NMEA 2000®« is a gateway for integrating fpCAN-equipped Fischer Panda generators with an NMEA 2000® network. The »Communication Interface CI – NMEA 2000®« converts fpCAN messages to NMEA 2000® messages so you can monitor your Fischer Panda Generator with NMEA 2000® displays.
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?
