Hi
I have a AB Compact logix connected with a HMI x-way Ethernet/IP to CAN J1939 Converter that is connected to a CAT engine.
I have an Input and output offset on 4 bytes in the x-way due to internal use in the module.
I am able to read the motor data that I want, but I am not able to adjust the engine throttle (write data).
I have tried SPN91 in PGN61443 (byte 2) resolution 0.4%/bit and SPN515 in PGN65247 (byte 2 and 3) resolution 0.125 rpm/bit in byte 2 and 32rpm/bit in byte 3 but with no success.
Is there any enable / disable bits that needs to be activated? I'm stuck. Any tips?
