Analytics & Calculations

One of the items i need to build frequently, yet no support in analytics yet. I want to habe an AF Analysis function that returns the number of seconds a value of an attribute has changed. E.g. to calculate how long a pump is running, how long a b...

As a PI system user, I need the ability to use reason codes to develop reports and dashboards. The current functionality of PI Vision symbols and analytics do not really enable the use of the current data type of EF attribute. The ability to map ...

It can be difficult to locate an analysis group in the current (2.9.5) UI for the Analysis Statistics in a large system. Currently the groups are organized in decreasing order of lag which is great to troubleshoot latency issues. However, if one w...

Allow a default value to be specified for rollup analysis. This value would be used when the rollup cannot find any matching attributes, thereby eliminating a lot of rollup analysis errors and Calc Failed values from being written.

A way to specify within the analyses if input values should be retrieved from the Data Archive or the PIAF Cache. Thereby preventing different results during real-time calculation and for instance backfills and decreasing the execution time of ana...

Right now BadVal can only check one variable or Expression.  So if I am evaluating an expression with say 10 inputs, and I want the expression to output NoOutput() if any one of the 10 inputs are BadVal, then I have 2 options right now. ...

It would be interesting to add the Replace function (like the one in StringBuilder) directly in AF Analysis

For recursive Analyses such as below : PrevVal(tagA,'*') + 'TagB' → output : tagA When the PI Analysis Service is down (or the node needs to be restarted), the current calculation needs to be halted until the Backfilling reaches up to the start u...

Add the triggers to SQC rules to reset or hold the SQC rule. When monitoring a periodic or batch based process, a user needs to be able to hold the SQC rule or put that rule in a hold state until the process resumes. Without this feature, virtuall...
