    I have a Installation of Scada Server on a Ubuntu Linux. I’am Reading Datapoints over Modbus TCP/IP connection. This works properly. After a few day i’am loosing some Datapoints. When i restart the Scada Server then works the system properly for a few new days.

    Thanks for Help

    Data are not lost. The values equal 0 from 12am to 12pm.
    The next time when the issue repeats, you need to check communication line log in Communicator and find out the cause of the error.

    Also check that Communicator is connected to SCADA-Server.

    Sometime the received data are incorrect. You can check it by http://modbus.rapidscada.net/ or any other Modbus parser. I recommend to try increasing a delay after request in Communicator (Request Sequence tab). Probably the polling speed is too fast for the particular device and network.
