    Get sustained value from a Tag

    Guevara

      Hi, I´m working with AF attributes and analysis to find out the amount of time in which a machine have been working BELOW a value, the first thing I did was write a function to figure out the last time that a value hits below a limit:

       

       

      FecUltPar= FindLT(Inst,'*', '*-200d', Limite)

       

       

      With that timestamp then I get the time using:  TimeLT (Inst, '*', ParseTime(FecUltPar), Limit)/86000 .

       

      The function Works nevertheless If I have "noise" (as I have) in the tag this does not reflects the operation of the asset, I´m looking for a way to get the timestamp but with a sustained time below of 2 hours at least.

       

      Any ideas of how can I get this?.

       

      Thank You.
