Analytics & Calculations

Some Analytics fail due to a tag not existing. It is possible to test for a Bad value via the BadVal() function, however, this does not work if the tag does not exist. Consequently the equation will not run. This caused me many hours of debugging ...

I would like to create a custom AFAnalysisRule that allows us to leverage the resources on the PI Analysis Service to perform calculations that the Analysis Service currently cannot perform. These calculations include matrix operations, array oper...

Please add PI FrequencyGT and PI FrequencyLT functions in AF analysis, like PI TimeGT and PI TimeLT, which find the frequency (number of times) within a range when an attribute value is greater or less than a given value.

Similar to the Exit() function, a Continue() function would be very helpful in reducing the calculation load on my analysis service, in this case by not fully executing variables if a condition is true. For example, if I'm evaluating the state of ...

Currently, the evaluate button can run your evaluation at the current timestamp and the last scheduled time. It would be really helpful to key in a 3rd timestamp to diagnose edge cases. The current workaround involves putting dummy variables in to...

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...

Add a quadratic regression function similar to "LinRegr". This would be helpful for trending relationships that are not linear, such as flow vs. pressure.

Now the TimeRules Natural and Periodic emit events to the Data PIPE in case NATURAL: an event is received by one of the selected inputs case PERIOD: when a certain timespan elapse.Both method doesn't take into account that some input of the analys...

Hello, We have a use case that would benefit from being able to insert into an AFTable from an analysis. This would work in the same way that event frames do, where a trigger condition is meet that causes the row to be inserted. The variables from...

We recommend customers use offsets to distribute scheduled calculations across time but there is not a good way manage this.Propose some utility to list a group of all scheduled analyses by same period, users supply X number of offsets and then th...
