I used Formula Builder to create a calculation that is the Max of six (6) temperature tags to derive the peak temperature for monitoring.

Is there a function or method that I can use to filter out tags that are reported with a Bad status by the source data historian system?

As it stands, my peak temperature calculation stopped updating because one of the 6 tags is Bad in the Aspentech IP.21 data source

Hi Yves! Great question - once data is indexed in TrendMiner, there is no distinction between good vs bad quality data. Unfortunately, TrendMiner does not pull in the data quality parameter from the data historian. A different representation of “bad” data would be a product feature request. I suggest adding this as a Feature Idea in the Community.

Thank you,

Kevin
