I am making a call to InterpolatedValues2 using different tags on the same server. The call is successful in one case and fails in the second.
Set pvalues = ipdata2.InterpolatedValues2(StartDate, EndDate, Period, FilterString)
The only things that changes are the tags in the filter string
This filter string works
"'CSO-PM3SPEED.REEL'<5000 and 'CSO-PM3SPEED.REEL'>400 and 'CSO-RMS3039'="CM020230" and 'CSO-M3BRK'="Off""
This one does not
"'MON-521SI0751.'<4000 and 'MON-521SI0751.'>500 and 'MON-PM2_GRADE'="USP 90" and 'MON-520X9144REEL.'="NORMAL""
If I remove
'MON-521SI0751.'<4000 and 'MON-521SI0751.'>500
the call completes sucessfully. I have confirmed that the tag MON-521SI0751. is a valid tag and has a normal range of 0 and 2500.
Can it be something with the way tag MON-521SI0751. is configured?
