I have a tag that monitors a batch number. I am trying to find a way to filter my results so it only shows the value and time stamp when the value changes instead of every single value that PI is historizing. The exception deviation did have a 5 minute max time so I was getting data points every 5 minutes even though the actual value had not changed. I turned this off hoping it fixes my issues but I would still like to know if there is a way to filter results (and show time stamp) based on an actual value changed
