    Hi Friends

    My server reads the data from a scada device and uses formulas to display it on the Webstation

    Now the problem is the scada server sometimes has a loss of signal for a few seconds to the scada device ( they are many Km apart .) This causes issues with the formulas and I get may mistakes on the Webstation from junk data .

    Does RapidScada have an internal function that I can uses in formulas to halt the calculations on a loss of signal , something I can built into formula .

    Something like
    {
    if LOSS_OF_SIGNAL
    STOP_CALCULATIONS
    Else
    DO_CALCULATIONS
    }

    Many thanks , Rich

    So If CnlStat>0 we have a good signal on this channel , thats my understanding .
    Is this correct .

    Thanks
