Analytics & Calculations

As an AF administrator, I would like to understand the difference between an analysis that is stopped by an end user, or an analysis that has stopped but should likely be running. Currently when an analysis is stopped, we do not know if this is ex...

TagTot will automatically account for UOM that have the time dimension as something other than per day only when the input has an assigned UOM and the function has an output UOM defined. It would be friendlier if the output UOM was defaulted based...

The first EFs created by the PI Analysis Service after a restart can have the Extended Property StatusInAnalysisService stuck in Reconciling even after the event frame has been closed. There is a workaround to fix the issue when it occurs (see Eve...

It can be difficult to clearly see the input/output trends in the prevew when trying to perform debugging. Specifically it would be useful to isolate the mapped output(s) to see if the analytic it producing the expected results. The table is usefu...

When taking a Total using Value Retrieval Method (configured in AF Attribute) or using TagTot (an AF Analytics function), PI will "fill in" gaps in the data. For instance, if you have a Float32 tag that is reading good for half of the day and then...

Recover data from the current time back rather than start of a data gap to now (current time). The most important thing is to get current data immediately.

Implement all the default calculations existing in EXCEL. We need to calculate the IRR (internal rate of return) for every technology: Inside the PI Analysis is not already available the function to calculate the IRR (like for the vb.net, Excel, ...

On more than one occasion, have missed several days worth of calculations with no indication of a problem. There were errors in the log, however there is nothing monitoring this log. The analytics service was running, but not actually doing anythi...

I would like to be able to define start trigger that fires a e new event frames only if the start condition changes. I mean: - Start trigger: 'Equip Status' = "ON" - End trigger: 'Equip rpm' >= 1000 I would like that the event start is triggere...
