GE Proficy Historian - How to exclude Bad Quality data from Delta type query

 So here is my issue.

The Totalizer tag is somewhat giving Bad Quality data for certain timing.

Bad quality data

Originally i could not be able to get the right hourly consumption bcoz of this Bad Tag data.

So the 1st step is to verify the tag settings. Using Configuration Hub - the correct settings was applied.

Delta Query settings for tag in Proficy Historian

The solution given by Edward is to correctly set the tag parameters and use some filtering function.

He proposed to add #ONLYGOOD in the Query String.

He also asked to use Delta Positive method.

But before we can use this method - the tag settings must be corrected also.

Problem solved !!
