Analytics & Calculations

PI System Explorer Management Tab should have better search criteria. For example, select specific elements in which to rerun an Analysis. Maybe use Element = something OR/AND Element = something else. Or search by element path.

it will be useful to schedule an analysis with a specific Time Zone in order to be aligned with the local time and, especially, with the local setting for DST.

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.

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...
