  1. Ability to identify faulty variables in AF

    When writing an expression analysis with many variables, if there is a missing ")" or an extra ")" then the whole analysis will not evaluate with error "Equation not set." This error does not help the user identify where the issue is. If PSE would back-light highlight the variable row in question or include the variable name within the error these would be much easier to identify and would save a lot of headache.

    In the attached screenshot is an example of "equation not set" where the issue is visible in the screenshot, but difficult to identify.

  2. Make Analytic Expression Editor window bigger

    The editor window for analytics is so small. If you create an analytic variable longer than 5 lines you have to start scrolling.

  3. When shrinking the tabs in the lower left pane of PI System Explorer (Elements, etc.), the tabs do not shrink if shrinking by one.

    When shrinking the tabs in the lower left pane of PI System Explorer (Elements, Event Frames, Library, etc.), the tabs do not shrink if shrinking by one. If shrinking by two, it only shrinks by 1, etc. These tabs should shrink accordingly.

  4. analysis template extension

    Analysis templates are useless if one need to adapt the analysis for some elements, for example in my case I need to change the "True for" clause in an Event Frame Generation Analysis, but I can't because it is created by a template.

  5. Null value for missing PI Point

    If a PI Point doesn't exist for an element attribute as part of a template, allow us to link the tag value to null. Currently if the PI point doesn't exist, the integrator or other client tools will raise PI point not found message. To get around the issue, we have to map the attribute to a tag that has a dummy value. It would make more sense for it be marked as a null value.

  6. Notification delay setting similar to True For on EF Gen analysis

    Allow the ability to configure a delay in sending Notifications so that they would only send if the triggering event frame is open for a configurable amount of time.

    This is possible at the analysis level using the True For setting; however, this does not allow to track all triggering events with Event Frames but only be notified for events that last for a certain duration.

  7. Analysis variable configuration from attribute value

    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 string value type could have the value "if '<attributeN>' = "OPEN" then 1 else 0. Then in the analysis, a variable could be simply configured as 'attribute1' and the configuration of the variable would be resolved and evaluated at runtime.

  8. give AF users the option to choose the write mode of an analysis in real time (replace existing value at a given timestamp, or not)

    When having calculationWaitTimeInSeconds set to a large value in combination with an AF-SDK app triggering recalculations, it can happen that recalculation writes a value at timestamp x before this analysis is triggered to run in real-time for timestamp x. This results in having 2 events in the archive, for the same timestamp. When having EFs making a summary eventweighed, this results in a wrong value being captured as some events will be counted twice.

  9. Restore Write access to Module Dabase after uninstalling AF link

    MDB to AF synchronisation is not needed anymore and new installation of data archive are free to not install it. Existing installations must maintain this link in order to allow PI-ACE to function properly and add new context. PI-ACE cannot be replaced by AF Analysis in certain circumstances. It should be possible to uninstall AF-link and restore write acces to MDB as of if it were never installed.

  10. PI Interface for Emerson DeltaV Syncade Batch - Allow EF creation for Phase Step and Phase State level

    Users would like to have the option to create event frames at the Phase Step or Phase State level using the PI Interface for Emerson DeltaV Syncade Batch.

    From the Live Library documentation for PI Interface for Emerson DeltaV Syncade Batch (Emerson start and stop events - Syncade: https://livelibrary.osisoft.com/LiveLibrary/content/en/int-batch-exe-v1/GUID-BE1AAAD0-DF13-4851-A762-2D27845BA73B): "Syncade does not provide phase state or phase step data."

  11. Create DLL that writes data from PI Web API

    Some kind of infomation such as PI Data Archive version is easily retrieved using PI Web API. If a DLL on AF is created to this end, retrieve the value obtained from a PI Web API URL, this king of information could be easily added to AF attributes.

  12. substitution parameter for point attribute

    At the moment i have to conifgure attributes like description or uom in PI Tags and also in the corresponding AF attribute. it would be great if i could use substitution paramertes like point.uom or point.descriptor in PI AF to fill configure Attribute parameters.

  13. PI Tag Name Search Count recorded in PI Tag

    Could the feature of counting the number of pi tags (by prefix) and display it in PI Tag or PI Vision. In Microsoft Excel's PI Builder, I would query for pi tags starting with "dist*" and get a count.

  14. Ability to disable variables in AF

    Within an expression analysis, it would be nice to be able to switch variables on/off for testing purposes. Commenting-out requires editing every line and also highlights the line as if it is in error. Being able to disable the variable with a switch would be useful

  15. Improve Asset Analytics Data Cache performance to handle large scale changes

    There is a considerable amount of downtime in our system (20+ minutes) when a template change is performed. The root cause is a limitation on how the analysis service handles the removal of AF Attributes from the Data Cache. Due to this limitation it takes a considerable amount of time to rebuild the cache.

  16. Rename the PIFD database to PIAssetFrameworkDb

    Nobody knows what PIFD means. We've had customer personell create PIDF2, PIFD3, etc. when tasked to create new AF databases, and also requests to remove PIFD because ICT personell don't know what it is.

    I suggest renaming the SQL Server database for AF to something more understandable. Following the naming structure used f.ex. by the PI Integrators, the name could be PIAssetFrameworkDb, or simply PIAFDB

  17. Be able to deselect Element Object Type

    It is currently not possible to deselect the Object Type "Element" in the "Select Object Tyoes and Column Headers" screen. This makes it annoying to search globally for things like Notification Rules and similar, as the results always include all Elements. Those then have to be filtered out, so that only the wanted Object type is left over. Finding and retrieving all the information for all elements can take a long while, depending on the size of the PI System.

  18. Feedback for the "Hardware and PI System Sizing Recommendations Spreadsheet"

    Please delete the blank hidden sheet. It's a useless waste of space.

    On the PI Data Archive sheet, please use named ranges to make your formulas more readable. This will also make it easier for you to catch any mistakes and quickly check if formulas are still valid for newer versions of the PI Data Archive.

  19. Use default servers and AF database from local KST for first time PI Builder users

    As a user, I want my experience to be as seamless as possible when using PI Builder so that I can get the information I need quicker.

    Currently, PI Builder will Default the servers/database chosen to <None> when a user first opens up PI Builder (after a fresh installation). I would prefer that PI Builder Default to the default servers and AF database from the local KST instead of <None>.

  20. Expression function to retrieve default attribute value

    I am migrating part of an old ACE application over to AF Analyses, and need to replicate the functionality to fall back to default values in case any of the input attributes are bad.

    I have taken the time to set the default value in each attribute template, so if one sets the Data Reference to None, the static attribute will have a correct, default value.

    But the analysis itself should contain functionality to revert to the default value if a bad input attribute value is detected, and with the current functionality I cannot access the default value. I will…
