Does the Range PE function return the difference between a tag's max and min value during the entire timeframe or only at the two end states of the interval?
If I'm looking at a tag in ten minute intervals, I only want to compare the value at time now (*) with the value time ten minutes ago (*-10m). I want to determine the range between only these points. I don't care what the other values are inbetween (or during the interval).
