    Thank you for your answers. what i don’t understand is after this:
    2019-06-17 17:00:23 Communication session with the Device 4 “Compresor 4”, type: KpModbus, call number: 4
    Request element group “Comp-DATA”
    2019-06-17 17:00:23 Error communicating with Device 4 “Compresor 4”: Error writing data: Uno de los dispositivos conectados al sistema no funciona.

    2019-06-17 17:00:23 Close serial port COM4

    the COM port remains blocked and no other app can open it, also if i try restart the computer it won’t restart remains on “Shutting down windows ” screen and i must reset it.

    Hi, are conected with USB to Rs485 converters, there are 2, each one conected to a USB port on the mainboard. Each converter pulls 2 RTU Slaves. But the test i made is only with one slave active.

    thank you for answer, but that string how is interpreted in comunicator ? maybe as ascii?
    Receive (4/4): ˇˇ^^

    the value that the device send is 41377 witch hex is a1 a1 followed by e5 e5 and the comunicator intrprets like this: Receive (4/4): ˇˇ^^

    Exists a method that comunicator intrpret id’s like decimal numbers ?
