I am trying to do something like this

if(IsQualityGood(DeltaBounds('[Energy.%Asset%.EnergyMeter]', '1h')),DeltaBounds('[Energy.%Asset%.EnergyMeter]', '1h'),if(IsQualityGood(Delta('[Energy.%Asset%.EnergyMeter]', '1h')),Delta('[Energy.%Asset%.EnergyMeter]', '1h'),Range2('[Energy.%Asset%.EnergyMeter]', '1h')))

but figured out that IsQualityGood takes tags and defaults to false here, is there a way that i can create a function does does what i intend here without having to create a tag for each of the functions withing the if?

Hi ,
The IsQualityGood() function will return a True/False, depending on the quality of the result. If you just want to return the actual quality, you will want to use Quality(). It will return the decimal quality format (192 = Good, 64 = Uncertain, 0 = Bad, etc.)

  Thanks , is there a way to get the quality of the result of a function like i was trying to do above? or is there a way to find out if the quality of a tag has been good for a set range like for the past 5 minutes? or maybe even exactly 5 minutes ago?

  Yeah. My U/I looks a little different here because I'm running a beta of 25.4, but you'll want to use 2 expressions, one for the function and one for the quality check. If you set the function equal to a variable, you can pass that variable name into the Quality() function.
