Why are my Backfilled Event Frame attributes not displaying the same in PI Vision as PI System Explorer?

aewan

Hi PI Square Slight smile

 

I have event frames that are being displayed in an Events Table.

I am using Formula DRs to check the other attributes of the event frame and present the data for display on the Event Table in Vision.

 

For the Event Frames that I have backfilled, or recalculated, the data does not display correctly and I get some No Data errors. In PI System Explorer, the data looks normal and there are no "No Data" errors. Whereas the normally generated events display correctly in PI Vision.

 

These display attributes are Enumeration Sets, and the normally generated Events display the correct Text of the enumeration state. The Backfilled events display the Enumeration State number instead.

The attributes that are showing No Data in PI Vision are also Formula DRs but they are referencing Event Frame Output Analyses.

 

PI AF Server 2.10.9.593

PI Vision 3.6.1.0

 

Any assistance would be thankfully appreciated Slight smile

cheers,

Andrew

In the screenshot you can see the top 3 rows are from backfilled events, while the bottom 3 were created normally.

    Hi again PI Square,

    So my company Mipac had seen something similar to this before, and we did a solution from PI that is the same as in this Knowledge Base Article: Formulas with input unit overrides do not convert in PI Vision

    Adding this: <add key="AFDRSetting:Formula" value="DisableInputs"/>

    to the PIDS_Settings.config file has fixed the Formulas to display as the Enumeration state value:

    But the No Data's here show correctly in PSE still but not here in Vision. They are a Formula DR that has and Event Frame output expression as part of the formula.

     

    I tried adding the following to the PIDS_Settings.config file too, to cover Analyses, but I did not see an improvement. Maybe it is the wrong text?

    <add key="AFDRSetting:Analysis" value="DisableInputs"/>
