Analytics & Calculations

Use case: User wants to trend Analysis Data Reference in client tools (Processbook, Coresight). User doesn’t want to create a PI tag for this output. Currently, the AnalysisDR ignores step, even if it’s input attributes are step.

We have come across a number of occasions where we want to bring in the last good value of an attribute as an input to an analytics.  But there is no way to do this without additional attributes and analytics.  It would be convenient if a function...

As an engineer, I want to execute analyses when I get a new future data value, so that any forecasts (either via Analysis or via a 3rd party system or via a PI Point update) can trigger analyses.

I would like to have monthly and yearly periodic trigger for Analysis-Expression and Event Frame Generation. Currently I have to use the daily trigger and check in the analysis if the month or the year changed. In case of “false” there is no outpu...

We have many calculations following this basic pattern - take recorded values of one attribute, apply a filter (using FilterData), then retrieve values of a second attribute at the filtered timestamps of the first attribute. Currently, we cannot r...

If an Analysis is triggered on "Any Input", and the inputs have the same timestamp but come in after each other, the Analysis is only triggered at the first input. For example: We have a simple Analysis which summarizes 2 tag. The first tag comes...

As an AF Administrator, I want to configure an Analysis Template for Event Frames with a True For parameter that would have it's value stored in an AF Attribute (configuration item). The use case is that elements built from the template will have ...

As a quality engineer, I need the ability to calculate Six Sigma SQC statitistics for key quality attirbutes.  Cp, Cpu, Cpl, Pp, Ppk

Currently PI Analysis Service has a built-in Statistics tool in PI System Explorer. It is able to show statistics regarding Evaluation and Calculation Lag as well as Skipped Evaluations and some other important information. PI System Explorer ...

As a user of analyses, I would like to have a Percentile function so that I can filter out atypical events when doing summary calls. The function would look like this: Percentile('attribute', 'timerange', value). This is related to enhancement req...
