    False received on or off devices

    Dear Stipus:

    I get too much change of devices status with no activity in de devices ... many events relay in the status of switch managed devices, so when I get a phantom on off device, events are false triggered. I do poll the devices every minute.
    Is there any work around?

    Double-check if live and neutral are correct on every PLCBUS module.

    If live and neutral are reversed on ANY module, it can cause problems to OTHER modules....

      Dear Stipus ... if all devices respond ok to a status request ... do you think there is a chance that one module had bad wiring?

        I can't be 100% certain.

        Here I had such problems with a plugin module that was plugged the wrong way.

        All modules still responded to status request, but this created weird Polling problems with other modules....

        - How many PlcBus modules do you have ? How long to check them all ?
        - Do you have plugin modules ?
        - Are you certain the PLCBUS 1141 interface is plugged correctly (live on live, neutral on neutral).
        - If you are not 100% certain (sometimes the wires are reversed before the wall socket)... try to plug your 1141 the other way (if your plug type makes it possible).

        Good luck... it took me a few hours to double-check every module with a live detector screw driver... and once every module and 1141 were live on live, random polling problems stopped.
