Analytics & Calculations

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...

Data can be flagged as questionable, which should mean the value may or may not be valid. Asset Analytics seems to be rejecting the value as Bad. The function instead should evaluate the result, but flagging the result as questionable as well.

When input PI Tags are referenced in PI Vision 2020+ calculations, they do not automatically detect PI Tag name changes. For users with a lot of calculations, this can be extremely problematic in the event of a PI Tag name change. In the event of ...

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...

This would allow for validation of input unit of measure during expressions.

Use case: 1. An element has an attribute that looks up information on equipment configuration (ex: a pump rate) 2.  Due to an equipment change, the lookup table and the element were increased in version 3. A backfill needed to be performed o...

I would like to be able to do a Rollup Analysis of Booleans attributes, without casting or converting the boolean. As Rollup Functions I would suggest: Logical AND, Logical OR and maybe Count of True/False. It can be use to create a Combined Stat...

Expression analyses allow you to find the largest value of an attribute over a specified time range using the TagMax function. A function which offers the ability the find the Kth largest value (i.e. 2nd, 3rd, etc.) would be useful. Something simi...

Currently there is no way to know if Analytics missed important updates (e.g. start of a batch) without analyzing the message logs. However, the AFSDK does provide an indication on the DataPipe if the pipe is in an overflow state, allowing for a c...

I would like to be able to insert a new variable above or below a highlighted variable, instead of having the new variable always go to the bottom of the list. This is very problematic when needing to add a new variable to the top of the list when...
