Hi All,
I have an Anybus communicator CAN to modbus TCP server.
I have setup several CAN produce frames to be sent
My problem is, I see no CAN frames being sent by the AnyBus, measured either at the AnyBus, or at my usb-CAN adapter that I am using to monitor the CAN network.
When I write using modbus to the relevant memory locations, the values at those memory locations revert back to 0 a moment later.
An example of one of the CAN frames:
writing to modbus 1026, using FC 6, 16 or 23 has no effect on the contents at that memory location:
When I set the CAN frame “update mode” to cyclically every 10ms, I still get no CAN frame.
I can send CAN frames to the AnyBus, matching to consume functions, and I can poll the relevant memory locations through modbus and see the right values change. This suggests to me the issue isn’t a comms issue.
Can anyone shed any light on why the Anybus server is not sending (producing) an CAN frames?
