  1. Return Partial Results From Event Frame Search in PI Web API

    Currently when searching for event frames, a 400 error is returned if not all elements in the search exist.

    piwebapi/eventFrames/search?databaseWebId=WebId&Element:IN("\server\AssetSwap\Site2\Asset1";"\server\AssetSwap\Site2\Asset2"

    This is cumbersome especially in the case of asset swapping in PI Vision when parent elements could contain variable child elements. For any parent element that contains less than the max child elements, a 400 error will occur when searching for event frames for related parent elements.

  2. Missing Open API (Swagger) specification for the Search controller

    The swagger specs for the search controller are not available. This will be useful in the client libs for searching

  3. Option to verify PI Data Archive connection during PI SDK installation

    During PI SDK installation, there is currently no option to verify the connection to the PI Data Archive. This can lead to complications if, for example, PI Interface Configuration Utility (which includes PI SDK) is the first piece of PI software installed on the machine and an invalid PI Data Archive name has been entered during the installation. Because there is no verification in the installer, the PI SDK and anything that relies on the Known Servers table entry such as interface.bat files must be corrected post-installation.

  4. Expose Values with Duplicate Timestamps in Transpose Function

    https://pisquare.osisoft.com/message/116957-pi-sql-commander-and-ssrs-how-to-retrieve-multiple-values-with-the-same-timstamp

    In the current implementation of the transpose archive in OLEDBEnt, a user is unable to retrieve data that may exist at the same timestamp as  another piece of data. This is because the time column is treated as the primary key of the transpose table. I would like to be able to retrieve all data using the archive transpose function regardless if timestamps are duplicated.

  5. AF SDK Async Data Methods for multiple AFAttributes

    Expose interfaces for asynchronous data method calls (ex. InterpolatedValues, PlotValues, RecordedValues, Summaries) that:
        1. Take an asynchronous enumerable of AFAttributes as input
        2. Output an asynchronous enumerable of results
        3. Throttle the calls made to PI Data Archive so that it does not overwhelm it

    The use case is to be able to make end-to-end asynchronous data method calls on a set of AFAttributes.

  6. Restrict Access to Web API Endpoint by User

  7. Expose Calculation.PercentTrue

    PercentTrue is missing in the WebAPI. Would you consider adding it? For some context, I come from here:

  8. Add Options for PI Web API Call Statistics

    Add auditing or a view of statistics for the calls or requests done by each individual application. Allow a PI Admin to see which user or application is making a specific call and see how long it takes to complete to monitor performance and potentially resource intensive Web API calls.

  9. Support Performance Equation Syntax for time parameters in the PI Web API

    As a Web API developer, I would like to be able to use time PE functions in the Web API using the streams/streamsets controller to allow for complex time queries.

  10. OPC DA Server should periodically update its cache from the PI Server after the initial start

    The OPC DA Server service uses %PIPC%\PI_OPCDA2\Data\SavedNamespace.xml to load the tags and does not update the  cache until  the service is stopped and started again. If any new tag is added to the PI Server, it is not picked by the OPC DA Server. The service should periodically update its cache from the PI Server after the initial start.

  11. Tag Creation

    As a developer of custom applications that use the PI  AF SDK, I'd like to be able to easily determine if an attribute based of an attribute template is configured for tag creation. Currently the AF Attribute Template class does not have this property. The current work around is to look at the configuration string which is less efficient.

  12. Allow PI OLEDB Enterprise client to specify which member of a PI Data Archive Collective to connect to.

    Enable functionality for PI OLEDB Enterprise that will allow the client to specify which member of a PI Data Archive collective they wish to connect to. This functionality has already been enabled for PSE and would like something similar for PI OLEDB Ent.

  13. Search on multiple Categories in AFSearch

    Several customers have asked for ability to search on multiple categories.  I understand from developers that a generic OR in AFSearch can be quite expensive, but allowing for search filter Category to support Equal or IN should not be expensive.

  16. Backfill/Recalculate over future data

    The ability to backfill an analysis using an end time in the future. This would read data from future inputs and write the results as future values.

  17. PI OLEDB Enterprise access to AF Tables

    Allow PI OLEDB Enterprise access to AF Tables.  The current workaround is to have the table live on a SQL database and then link to them from AF.

  18. PI TagMedian function need to be added in AF analysis.

    Please add PI TagMedian function in AF analysis like PI TagAvg and PI TagMean. Currently Median function is available but it cannot be applied for archive values of PI Tags during particular time range

  19. Add a PI Collective member info PI WebAPI controller

    As an end-user, I want to be able to see to which PI Collective member I am connecting to. I also want to be able to toggle programmatically from one PI Collective member to the other so I can make sure the informaiton I am seeing is aligned and in synch accross all PI Collective members without going into thick PI clients or through log files.

    This is a novel idea for monitoring PI Collective health, but there are no plans to add this ability to PI Web API. What advantages do you see in using PI Web API here?

  20. Support attribute types referencing AF Elements and Attributes

    We use attributes to reference elements and attributes extensively to model context and relationships in our AF models. Is this going to be supported in the future? Kind regards, Gregor

    This item is under review. Currently considering the following behavior for attributes links:
    Current behavior:
    Error returned: “Unsupported data type: ‘OSIsoft.AF.Asset.AFAttribute’.”
    Similar error for AFElement.

    Change under consideration:
    Value link for Attributes of value type “Attribute” returns the referenced attribute’s GET response (“/attributes/[webid]”)
    Value link for Attributes of value type “Element” returns the referenced element’s GET response (“/elements/[webid]”)
