Analytics & Calculations

For our technical account we have to do recalulations on a daily basis, because of late arriving data. Auto-recalculation is not an option, because late arriving data that arrives after we have published the results, should not(!) be respected any...

We had a few issues with key-users creating inefficient AF Analysis and starting a backfill over a longer time period. This resulted in a CPU load of 100% (caused by the PIRecalculationprocessor). The whole PI System got not responsive incl. PI Sy...

Please provide a 'GoTo' like Funciton for Analysis Expressions to skip expressions or maybe even go back to a previous Expression. I realize you don't have line numbers per se, but if the Expressions operate in order, could you use the Variable Na...

As someone who has migrated our calculations from PI ACE to Asset Analytics, we need to be able to annotate various calculation outputs in the same way we were able to with PI ACE. Please enable analyses to output annotations to various PI Tags in...

As an AF administrator, I would like to understand the difference between an analysis that is stopped by an end user, or an analysis that has stopped but should likely be running. Currently when an analysis is stopped, we do not know if this is ex...

When taking a Total using Value Retrieval Method (configured in AF Attribute) or using TagTot (an AF Analytics function), PI will "fill in" gaps in the data. For instance, if you have a Float32 tag that is reading good for half of the day and then...

On more than one occasion, have missed several days worth of calculations with no indication of a problem. There were errors in the log, however there is nothing monitoring this log. The analytics service was running, but not actually doing anythi...

I would like to be able to define start trigger that fires a e new event frames only if the start condition changes. I mean: - Start trigger: 'Equip Status' = "ON" - End trigger: 'Equip rpm' >= 1000 I would like that the event start is triggere...

AF (and PE) expressions currently have AND and OR operators. These work either logically or (if both operands are integer) in a bitwise fashion. There should also be an XOR operator that works the same way, to avoid the messy construct (A AND NOT ...

After generating "Preview Results" (from right mouse click on analysis name on PSE Analysis Templates tab) it would be nice if the upper results table would auto scroll to the related time value when using the trend cursor to click on the results ...
