Analytics & Calculations

It would be nice if the PI Analysis Service could pick up a change in the Cache Refresh Interval of any AF Table being referenced by input attributes with a table lookup data reference. Currently, a service restart is required.

Derived templates (element and event frame) will not allow for inherited attributes to be used as the "Default Attribute". This breaks inherited analyses that use the "Default Attribute". The only workaround is to override the the attribute, which...

Currently, when the Data Cache is signed up for updates on multiple data archives, updates from each archive are fetched in series, one after another. When there are many data archives involved (especially if they are geographically dispersed) thi...

In AF/Analytics 2018, implicit modes of Event Frame generation were introduced (Pulse, Step, and Step Continuous), but they do not allow for an output expression like the explicit trigger. Adding this functionality would allow for EF attribute val...

As a PI user, I want to be able to visualize and analyze the SQC violations that are generated by the SQC rules.  The ability to save SQC outputs such as  Mean, median, mode, stdev, Cpk, max, min, 1-5 sigma zones, ucl, lcl in the follo...

Use Case: calculating which Shift is working within a rotating-shift cycle, which must the follow Daylight Savings Time offset. This function is available in the Performance Equation library, but not in AF. The function itself is simple once one ...

I would like to be able to order by name (alphanumerically) the Analysis in the Management tab in PI System Explorer after retrieving a list of analyses through a search/filtering. This could be done by clicking on the Name column.

A useful setting for PI Analytics would be the ability to specify a specific pointsource that the Analytic service writes to. This would help tremendously to troubleshoot what tags on the PI DA server are being written to by AF Analytics.

As for now, automatic recalculation is not triggered by changes on snapshot (KB01790), which means auto-recalculation does not work with snapshots values. The idea of it doing otherwise is to help users that mistakenly added a wrong new event to ...

From a varying number of child elements (all sharing the same template), I want to find the most recent timestamp of a same template-based attribute, and output the value with timestamp to an attribute in the parent element. In addition, constantl...
