Having problem when displaying the AF analysis value in PI Vision. Its shows intermittent “calc failed” in future date. However, the AF analysis value show correct value in PSE.
Looks like you are using Analysis data reference i.e. dynamic calculation. PI Vision displays values based on end time of the display. You can move the end time of the display to match the output attrbute time (future) and it will show the result else it will result is calc failed especially for dynamic calculation
I agree with Lal, if that doesn't work check the clocks on the PI Vision node and the PI Data Archive node to make sure they are in sync.
Hi Lal / Sebastien,
The PI Vision is showing the current time but the AF analysis display value is showing future data (refer figure below). one more thing the data archive and pi vision was in the same node. so time is correct.
If you put the same time range in Preview Results in PI System Explorer, do you see Calc Failed or a value?
I can see value instead of calc failed. By the way, after monitored a few days the error is not happen anymore.
