Analytics & Calculations

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...

The customer has created some PI AF analyses these analyses trigger based on Event-Triggered. However, the customer his wondering if she can write a value to the output attribute before the analysis triggering for the first time. As of now, we onl...

I would like to have new analytics functions Find(attribute attname, time startTime, timeendTime, string filter) and TimeTrue(attribute attname, time startTime, timeendTime, string filter) similar to FindEq() and TimeEq() but with flexible filter ...

In case of only reading the attributes of the tag structure during an analysis/calculation, as tagname, tagnum, etc. could there be a way to put the attribute even though it's an output. Background: Customer is using analysis template where some o...

Currently, PI has an FFT interface. I would like to take this functionality and implement it within Asset Analytics so that we can understand the dominant frequencies of our continuous process data without having to support a separate custom appli...
