  1. Create 2 new client install kits: PI System Client & PI For Excel

    Administrators and regular users of PI are mainly concerned with these PI client programs:
    • PI System Management Tools
    • PI System Explorer
    • PI Builder
    • PI DataLink

    However, the install kits are not beginner-friendly:
    • Many users think that PI DataLink can do what PI Builder does, since both are Excel add-ins.
    • PI System Explorer and PI Builder are grouped as a single program called "PI AF Client" in install kits, including the install kit of the same name. This makes it difficult for users to find these programs.
    • The PI System Management Tools install kit…

  2. Enable Compression for recalculated Analyses up to "Now"

    Analysis Recalculation produces Out of Order Events, which means they are not compressed.
    The reason for this behavior is, that there is a more recent snapshot value existing. This also happens, when Recalculation is performed till "Now" (*), because the Analysis Service performs the Recalculation in chunks (see "Will PI Analysis Recalculation follow compression and exception?")

    Would it be possible to make the Analysis Service first delete the time range fully (when recalculating up to "Now") and let it perform the recalculation in chunks afterward?
    This would not produce OOO Events and compression can be applied.

    The only workaround at…

  3. Expose backfilling/recalculation status in the AFSDK

    Currently analysis runtime information can be accessed programmatically using the AFSDK (AFAnalysisService.RuntimeInformationFields - https://techsupport.osisoft.com/Documentation/PI-AF-SDK/html/POSIsoftAFAnalysisAFAnalysisService_RuntimeInformationFields.htm). However, there are no fields which can be specified corresponding to backfilling/recalculation status of an analysis.

    Adding a field for the aforementioned property or introducing a new method which could expose backfilling/recalculation status would be helpful for finding backfilling/recalculation errors programmatically. This approach should be much faster than finding analyses with backfilling errors in PSE.

  4. Show inherited Attributes on derived Templates, just like inherited Analysis are shown on derived Templates.

    I would like to view inherited Attributes on the derived templated. It should be disabled to edit. Just like inherited Analysis are shown on derived templates.

  5. Enable Data Fanning for PI Collectives through PI System Management Tools

    Currently, PI System Management Tools supports buffering but not data fanning (does not send data to all collective members).

    When using a PI Collective, customers would like to make changes to PI Point values in Archive Editor in the Primary Data Archive and see those changes replicated to the Secondary Data Archive when buffering is enabled.

  6. Support AWS RDS SQL Server instances as backend DBs for AF and PI Vision

    Our company is progressively superseding the deployment of hosts with SQL Server installed, while moving towards the usage of SQL Server instances provided by AWS' Relational Database Service as the DB backend. Although currently OSISoft does not officially support the usage of RDS instances as backends for AF and PI Vision, we performed some internal tests with both AF and Vision and they seem to be promising. We would like OSISoft to study this kind of solution and, if there are no major obstructions, provide official support for such scenarios.

  7. Analysis tab can be slow to load

    The analysis tab in PSE can take quite some time to load if there are thousands of elements being referenced in the input attributes. This is rare for Expression, Event Frame and SQC analyses, but not as rare for Rollups. Ideally the tab should load faster, or at the very least the UI should not be blocked while the tab is loading.

  8. Separate priority setting for Data Read and Data Write

    Data Read and Date Write (Buffering) from/to PI Data Archive is based on the priority settings in PI SDK and PSE. We have a architecture of 6 member PI collective and all the source data is not buffered to the individual collective. Hence for other applications like PI Analysis or any other 3rd party applications data read should from couple of collective members and data write should be to 4 collective members.
    As per the current setup, if we enable the priority for 2 members in collective, data read and write is happening only for those members (Default behavior). But…

  9. PI AF Link & PIBatch - Ability to uninstall it

    PI AF Link is not included in PI 2018 but it would be good to be able to remove the link during an upgrade. (not possible today https://customers.osisoft.com/s/knowledgearticle?knowledgeArticleUrl=000027668).
    Same for PIBatch which cannot be uninstalled even when not licensed for (recommended to disable service https://customers.osisoft.com/s/knowledgearticle?knowledgeArticleUrl=PIBatchsubsystemdoesntstartBatch)

  10. Make badval() in Formula data reference equivalent to BadVal() in Analytics

    Currently, BadVal() in Asset Analytics can handle situations like BadVal(1/0) without throwing a divide by zero error, but the badval() function in the Formula DR cannot. The request is to make them equivalent so that behavior is consistent across the product.

  11. Keeping old events that have been manually worked on in case of Recalculation/Backfill

    Case 1.
    There are some EFs that should be acknowledged and commented by equipment owners. In Pharma World, these comments qualify as GxP and shall not be deleted. Whereas Event Frames generated by analysis can sometimes due to data coming late or analysis errors be faulty. If by recalculation the EF attributes are corrected with data, the user will not be notified of the change, and the comment would be faulty. And if the error is in the trigger tags, and they will be changed afterwards, while recalculating the event would be completely different, and the comments are therefor not…

  12. Preview Results should display values of variables in event frame generation analysis

    If I want to create an analysis that generates an event frame in PI System Explorer, often times it's useful to check the values of variables to make sure that a calculation is being done as expected to mitigate error on my end, and make sure I am doing the calculation properly and have correct syntax for the order of operations (as an example). This can be done with expression types, which makes it easy to see the values of all the attributes and variables used in the analysis for a given time. There may also be a threshold that…

  13. Optimize the storage and retrieval of digital tags

    Given that the archive file format is proprietary, this suggestion is me shooting in the dark.

    Disk compression compresses archive files very well, and my guess is that most of this compression occurs on the digital tags, since the number of possible values that they can take on is limited. In contrast, the number of possible values that a floating-point tag can have is huge, so there is not much opportunity for compression.

    Please consider optimizing the storage of digital tags so that their data takes up less space in the archive and can potentially be retrieved faster.

  14. Filter/Flag PI System Generated Error Message as Analysis Inputs to prevent False Positive Evaluations

    The PI data archive (and potentially other systems) can generate many automated error messages to assist with troubleshooting. One such key example is "[-10767] Client exceeded maximum concurrent queries in RPC thread pool", which occurs when a service (such as AF Analyses) doesn't have adequate threads to retrieve input values.

    If this error is given because of a system issue, the Asset Analysis service will still process the logic with that error message being used a generic string. If the logic is something similar to Input <>1, then this would resolve as TRUE. In this scenario, this would be a…

  16. Ability to manage non-impersonated linked tables without PI AF Server Admin privilegies

    PI AF Admin would like grant permissions for users that are not level server admins to create and edit non-impersonated linked tables. Currently this only allowed for AF server admins or using impersonated linked tables.

  17. Add Process Capability Statistics fundtions (Cpk, Ppk)

    While it is possible to manually calculate Process Capability Statistics, such as Cpk and Ppk, using AF Asset Analytics, it would be much more convenient to have a built in function to calculate these values, specifically in relation to the SQC Western Electric rules analyses available in AF asset analytics already.

  19. Date and time format in Preview-Results pane (PI System Explorer) to be consistent with all other date & time formats

    The Date and time format in PI System Explorer's Preview-Results pane are not displayed according to the end user's operating system date & time format defined. This is an inconsistent behavior to that of PI System explorer in general sine the application displays date & time formats according to the OS settings in all other fields.

    In the attached example one can see that the start\end date & time formats displayed on the trend's X-axis are correct (comparing to local OS settings) as oppose to the ones displayed in the Preview-Results pane...

  20. Ability to edit "escalation team" member priority in PI Builder

    There is currently no way to edit priority for member of an escalation team in bulk, it has to be done one by one in PSE. For users that have 30+ escalation teams, this is a lot of tedious work. it would be nice to be able to pull in the escalation team object with its members and their priority number, edit the priority numbers, and publish to AF.
