I am trying to get sampled, interpolated (at 30 second intervals), evenly spaced data using PowerShell but am having some issues.
Using Get-PIValue I'm able to get an interpolated value by using a single timestamp but not with a start & end time. The way I'm doing it now is using a while loop and incrementing my timestamp by 30 seconds each time and using the -ArchiveMode Interpolated each time.
PI-ExpressionSummary makes me specify a SummaryType, none of which would be an interpolated sample.
Is there a method to do this by just passing in a tag, start, & end time?
