Analytics & Calculations

Instead of putting all non-templatized analyses in one group for evaluation, the PI Analysis Service should divide them up automatically according to some criteria. The goals would be: 1) Eliminate the need for many "one-off" templates that cause ...

It'd be nice to dynamically set the Event Frame category within Asset Analytics. Preferably have this as an option for each 'Start Trigger'. This would be advantageous since 'category' is on the top level object and thus much more efficient to q...

While it is possible to manually calculate Process Capability Statistics, such as Cpk and Ppk, using AF Asset Analytics, it would be much more convenient to have a built in function to calculate these values, specifically in relation to the SQC We...

When working with arrays in PI Analysis it would be nice to be able to compare a current value against the previous or next value. I have figured out that I can use PrevVal in the MapData function, however it appears that this goes back to data ar...

Our process is writing an array of strings into an AF attribute of the same type. This AF attribute may receive information of different size (index) in time. We need to extract all the information contained in the string array (all the items) an...

It would be extremely helpful if a function existed within PI AF where could provided a value/tag reference and a bit number to check and see if its active. The function would return a True or False value if that bit is active. Something like the ...

The TriggeredOn() function would return true if the inserted attribute was the reason for the expression analysis to trigger/evaluate. I have multiple attributes in the same analysis but only want each line to have an output when its corresponding...

I'd like better diagnostic information around why event frames are not create by AF Analytics so that my solutions are of high quality and my users have confidence in their EF data.

As a user I would like the ability to prevent "Preview Results" from generating a plot.  The plot takes a ton of time to fill in, and often, I care more about the actual data row-by-row than I do about the trend.  It's frustrating to kno...

Behind the scenes, Analytics groups calculations during startup of the PI Analysis service.  However, after startup, sometimes an Analysis 'falls' out of a group and cannot be added back.  This returns the error message, "Failed to inser...
