PI Interface for OPC DA has a plugin called "Time Array" to manage numerical arrays but string arrays are not supported.
It would be a good improvement to develop this feature for string arrays.

When mouseover on a output attribute analysis icon the analysis is displayed in the tooltip on a single line. The analysis will quickly become unreadable.

It would be nice if the analysis could be presented in a readable way.

As a PI System admin, I would like event frames with multiple start triggers to match preview results when the parent Event Frame's start time is adjusted during Event Frame reconciliation. Currently we have to take one of the following actions to prevent the duplicate event frames:

Wait until the event frames are closed and then recalculate the event frame analysis

Manually delete the duplicates

Reconfigure our Event Frames to contain just one start trigger

To use the PI Server with the Microsft PowerPlatform, a custom connector is required.
This connector is always under the responsibility of the customer, which makes it difficult to keep up with adjustments to the PI system and Microsoft, or to react to them.
Instead of the custom connector there should be a standard connector, which is supported by OSIsoft and Microsoft.
Through this connector the two platforms can ideally work together.

Having more thorough and detailed messages for the Analysis service in the event logs, especially upon startup.

Environment details + Language settings that the Analysis service is using should be mentioned in the startup logs in order to better troubleshoot configuration issues without needing to go through a trial and error process.

Negative numbers in digitalsets for all PI interface and skip numbers, basically that the digitalset is like the enum of AF

It is possible to search for Templates, Elements and Attributes, however the only way to obtain Analyses is to perform a full Element search then filter out the Analyses columns.
I have an extensive AF structure with many 100,000 rows. It would be useful for such large AF structures to be able to search for Analyses in the same way that you can search for Elements or Attributes.

Ability to allow extensions in PI AF Analysis template, in order to modify specific element analysis.

I would like to be able to reference the parent of a element reference. As it currently stands, it is only possible to reference the original parent element of an element.

Creating a possibility to populate PI-tag's based on the Events. These PI-tag's can be used in reports/displays. Generating batch, daily, hourly, shift and other "event" driven values and store them in a specific PI-tags would very easy and may reduce the performance load of the system. Calculations are triggered only when the events happens. Possible solutions: 1) Adding a Analysis tab to the EF frame template for mapping/calculations 3) Extend the Output Expression to enable the use of EF (child)attributes 2) Extending the function EventFrame enable the use "EF (child)attributes names" instead of 'Starttime','EndTime,'Duration' only

As a user, I'd like to have a Calculated Data option when i select the Time Series Data of an attribute. This would let me pick out things like 5 minute averages, 1 week range etc etc.
It would put data in end users hands without having to request it from the engineering team or learning PI Datalink.
Right now, its only Sampled Data or Archive (Raw) Data available.

Unfortunatly PI Notfication is an very old tool.
The Tool is very old and slow.
Improvements are needed.

Improvements needed:
1. Performance Update for the engineering tool in the AF is very poor
2. Functionality to send an event to an webapi is very basic. we need more functionality to connect also webapi's with a very strong authentification concept

In many UseCases we need more programability functions in PI. As example loop functions. We like the AF Framework, beacuse if you search in case of a problem you are very fast. But the functionaclity is unfortunatly not very rich.

Please integrate some more functions or integrate NodeJS, Phyton or
other scripting capabilities

We use PI in an multilingual context.
Therefore we need an functionality to support.

It would be good if you could enter a translation list for several languages for all elements and attributes. This language must be selectable and accessible via all interfaces as well as via PI VIsion.

When using the recorded values function in Analysis, Time weighted totals and averages assumes that the data is continuous and not discrete. This creates issues with data streams that are both discrete and require time weighting functions. Ideally a third calculation type needs to be added to Total, AVG and the like which is Time Weighted Discrete. This will adress this issue as is currently done in TagTot or TagAvg.

Transfer Saved searches: This option will allow transferring event frames "saved searches" from one computer to another. For customers who have many search criteria, it is time-consuming to rebuild again on another PC.
