Analytics & Calculations

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...

Currently you can only run a single PI Analytics instance at a time. We have two VMs running PI Analytics in a failover situation, but this means that one of the VMs is sitting idle 99% of the time. We are starting to hit the limits of scaling w...

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...

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 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...

As an AF administrator, I want to configure analysis template names using Substitution Parameters to distinguish analysis from each other with PSE and in AF SDK Applications.

Provide a basic library of analysis to answer simple questions about assets : how many cycles on/off last year ? How long did it run over 90% last week? This library should manage the data quality
