Analytics & Calculations

In order to calculate the current shift operating at a plant, I need to calculate where in the 28-day cycle the current week is. Knowing which week of the year it is allows me to do that. Note that current PI weekday functions always count Sunday ...

Allow a default value to be specified for rollup analysis. This value would be used when the rollup cannot find any matching attributes, thereby eliminating a lot of rollup analysis errors and Calc Failed values from being written.

By now the NumOfChanges Function in AF Analytics does not take into account the value at the start of the timerange. NumOfChanges only counts the amount of changed values of the recorded values in the given timeframe. If I query the NumOfChanges ...

Right now BadVal can only check one variable or Expression.  So if I am evaluating an expression with say 10 inputs, and I want the expression to output NoOutput() if any one of the 10 inputs are BadVal, then I have 2 options right now. ...

For recursive Analyses such as below : PrevVal(tagA,'*') + 'TagB' → output : tagA When the PI Analysis Service is down (or the node needs to be restarted), the current calculation needs to be halted until the Backfilling reaches up to the start u...

As a user configuring Analyses, I would the the Performance Equation (PE) Editor's auto-complete to suggest any child attributes as well as regular attributes.  Note: This was previously Enhancement 109589.

As a End User I would like the Analysis Curve Function to accept referenced attributes and internal calculation variables for numeric constants (x1,y1) (x2,y2) (xn,yn) so that the resulting y value is based on a dynamically updating curve function...

As a PI Administrator/Super User, I want to control which users can start or stop analyses. This would allow users to create analyses and preview their results, and for administrators to review them before they are put into production.

It would be interesting to add the Replace function (like the one in StringBuilder) directly in AF Analysis

A way to specify within the analyses if input values should be retrieved from the Data Archive or the PIAF Cache. Thereby preventing different results during real-time calculation and for instance backfills and decreasing the execution time of ana...
