Is there a way to calculate the maximum value less than xxxx over a period of time?
I have few tags that show some outlier values as shown below, I want to find the maximum value over time filtering out the outliers. I tried datalink using the maximum value in the calculated data function, I added the filter expression 'Mytag' < 15000 which I thought it will leave out the outliers but that didn't work. The function is still returning the outlier value.
Any Idea how I could get what I'm looking for?
