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 ...

The Suggested PI Point Name configuration item in the AF Client should be able to be set on a AF Server basis instead of a User basis, at least as the initial default. There are default parameters we need to enforce from an enterprise/site level b...

I need to calculate a running sum (totalizer) of a PI Point and reset it to 0 at the beginning of each month. I would like to do this with Asset based Analytics. There are workarounds to do this, but none are great. For example, one workaround inv...

As an AF Asset Analytics user, I would like there to be an option to output a value rather than 'Calc Failed' if an analysis fails to evaluate.  I have several aggregate analyses which are dependent on other analyses (which will occasionally ...

It should be possible to force an apparent circularity to be ignored if analyses are scheduled and not triggered. A thermal efficiency application I have coded as AF Analyses has the following two analyses A and B, such that each is expressed in ...

As a consumer of event frame data, I would like to be able to get a summary of the children event frame duration based on the trigger or severity over the duration of parent event frame when a parent event frame closes. The output should be stored...

I use analysis to toggle a boolean or integer from 0 to 1. This is used as source to close/open event frames (step continious mode). this is working fine in real-time. But when I do a recalculation for a part of time in the past (not until *) on t...

Having the ability to store analysis variable configuration (calculation) in an attribute value would help a lot in creating assets from template that have diverging analysis configuration. For example, an attribute named attribute1 with a strin...

This suggestion is on how you manage the input tags into calculation that at some point it returned bad value (like I/O Timeout, Bad Input, Snapfix, etc...) or became questionable. These tags will make your calc at analysis become "Calc Failed". I...

Currently it's not possible to use attributes that are based on a PI Point Data Reference with RelativeTime or TimeRange settings as triggers for analyses with event-triggered scheduling. You get the "No valid triggering inputs found" error. The r...
