TīmeklisIn this scenario, one BridgeWay device will be required for each J1939 engine network. The BridgeWay can then have the same J1939 (CAN) address on each individual network, but the host (Ethernet, Modbus RTU, or PROFIBUS) address will have to be unique for each gateway if using a single PLC to read/write data through each gateway. TīmeklisIn practice, J1939 conversion is often done by extracting the 18-bit J1939 PGN from the CAN ID and the DBC ID and then comparing the PGNs. The method depends on your software. In the CANedge tools like asammdf and our Python API tools, loading a J1939 DBC will automatically make the tools use J1939 PGN matching.
