    Hi there,
    still looking for a solution. Any hint would be fine for me...

    I also tested another modbus slave - and here it's working perfectly. So maybe akytec has a problem with the alive signal??

    Check your screenshot #7.
    Change Unit ID from 255 to 1.

    Kislov, thank you very much! That's it! Now its running :)

    For all the others:
    Here is the screenshot for the setting.
    Seems the Akytec module has an internal gateway to modbus rtu and therefore unit id 1 is needed, not 255. 255 is for the gateway itself.

    Regards,
    Mike
