Analytics & Calculations

Normally AF function PrevEvent() returns the timestamp of the previous event for a specified timestamp. But if the previous event is system digital state "No Data" it does not return the timestamp but again system digital state "No Data". That is...

If you have a PI Tag that fluctuates within very excessive ranges, then it becomes quite difficult to observe its trending patterns in a chart because of its volatility. A feature to smooth the volatile values (i.e. exclude those outside of a use...

Background: Currently, the only why to troubleshoot the analysis service is to set the trace levels through the various config files.  This only works when the analytic engine is being used.  In other words, this only works if the analy...

Currently it is only possible to specify one timestamp override per analysis.  I would like a way to set a conditional based timestamp override that way the output timestamp could vary based on the result of an analysis.

When I open PI System Explorer and click the Management button in the bottom-left I'd like the ability to show and hide certain columns of information; for example, I'd like to be able to add the Analysis Description as a column.

The traceability of cross-element analysis in the PI System Explorer would be greatly improved by using jump labels on relative or absolute paths in the expression or in the ConfigStrings. For example, you could jump to the referenced element or a...

As control engineer, i think it´s necesary to include some flow control functions, as for next, while, etc; and the capacity to do Iterative functions.

The upper edge of the blue part of the Functions pane should be resizable. If this edge is moved upwards, the entire function description can be viewed without having to scroll. If this edge is moved downwards, more functions in the list can be vi...

It's often convenient to bulk select all Asset Analytics and start them all, but sometimes there are some analytics you want to ensure are never started for example a Template with a rollup analysis is instantiated somewhere but has no children to...

Create rate based Performance counters for analytics & Calculations instead of counts. For example counting the number of EFs created over time is not as helpful as knowing the rate at which i create EFs. The rate would allow me to catch spike...
