I see your function is being called as =PIArcVal("PIML: RBC #1 Biological Growth",$X14,$Y14,0,"","interpolated")
There are 6 parameters in the function but PIArcVal should have only 5 parameters: PIArcVal(DataItem, TimeStamp, OutCode, RootPath, Mode)
Could you please rebuild the expression by using the right panel to see if it gets fixed?
Thank you for your input.
I went ahead and made the change to =PIArcVal("PIML: RBC #1 Biological Growth",$X14:$Y14,0,"","interpolated") but now the error I get is “Tag Not Found”.
I see there is a range in the Timestamp field now. The PIArcVal is a single timestamp function. Maybe you are looking for the Timed Data Function?
Note that you need to select a single cell for each output cell when using PIArcVal.
If you want to have all the values with a single function you should use the PITimeDat function.
Hope this helps.
