Does the tags zero setting do anything? I have many tags with a zero = 0 yet they still store negative values in the data archive. I thought that values not between zero and zero+span would be filtered out.
I am attempting to create an AF analytic using Tagmax - Tagmin to determine a maximum rate of change within a time period. However, data outliers are creating false high rate of change alerts.
I am using Pi Data Archive 2015 R2.
