I'm having trouble getting the scan function to work for CANbus Layer 2 functions with a V130. I have gotten the Send function to work (device functions), so I think my configuration is fine. When I run the scan function, the received data appears at the location vector (MI 37) but the data is never stored at MI 30. This is likely because MB 3 is never ON. When I run Online Test it shows MB 3 temporarily ON (as it should) but I'm skeptical if this is truly working. The CAN ID is correct.
Am using the scan function correctly? Are there any examples of how to use the CANbus Layer 2 functions on the V130? Could there be any hardware problems? I have 120 ohm resistors at each end of the bus.
