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?.
