Hello, I am trying to perform a Calculation on a tag value and having trouble via PI Calculations
I have a new calculation open
Name: Extruder Speed
Description: extruder calculated speed
Stepped Plot box is checked
1m refresh interval
Server is our PI server
Tag or Expression: 'HSP_MASS_FREQ_EH_REF' / 12.7
Interval: 10m
Sync Time: 00:00:00
When I try to click ok I get an "Error Evaluating Tag or Expression"
Tag name is selected directly from Tag Search field and matches exactly, If I remove the single quotes from the tag and the (/ 12.7) it will allow me to created the Data Set.....so it does recognize the tag. However, if I put the single quotes back around the tag name it yields the Error message again!
Can not find anything in help files or searching through this forum...
Thank you,
Drew
