  1. Reset Attribute to Template method in PI Web API

    Synced to PI Square at https://pisquare.osisoft.com/ideas/29447

    As a developer using PI Web API, I would like to have a Reset an attribute to template method using the Web API so I can program with greater flexibility.

    I am attempting to create a .NET Core App and this limitation prevents us from using PI Web API exclusively in automated AF Builds

  2. Add support for AFFile type

    To support reading/writing files stored in AF. Read is more important though.
    Started from here: https://pisquare.osisoft.com/thread/37635-access-pdftextdoc-files-from-af-server

    I want to be able to use AF as a one-stop place to access my Asset Data. Therefore i want to be able to access Files stored in AF to provide this data alongside all other data through the PI Web API.

  3. AF SDK Calls using the AFValues.GetValues should include an index of result events, this is to allow direct location of replacement events

    The PIPoint.ReplaceValues method requires a replacement of every event in the timerange, however it also may reorder or miss events with the same time stamp. The issue is that if the client wants to replace only a certain event, but must find that event - the replacement is for all the events at that timestamp and the method doesn't seem to allow for precise replacement of a value.
    The use case is programmatic correction of operator manual entry error, where multiple events have the same timestamp.

  4. Add point attributes such as "instrumenttag" to "fields" for search controller

    Currently, as shown in the link below,

    https://techsupport.osisoft.com/Documentation/PI-Web-API/help/controllers/search/actions/query.html

    The "instrumenttag" as well as other PI point attributes are not selectable in "fields".

    The selectable ones are shown below:

    afcategory; attributes; datatype; description; endtime; haschildren; itemtype; links; matchedfields; name; plottable; starttime; template; uniqueid; uom; webid

  5. 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.

  6. Expose AF element modification timestamps to WebAPI

    Expose AF element modification timestamps to WebAPI so that caching mechanisms in middle ware or consumer apps have a programmatic way to determine if the structure needs to be crawled/refreshed.

  8. Be able to override the default value for the maximum number of items returned by a query.

    We would like to override the default value for the maximum number of items returned by a query. Currently, the MaxCount parameter needs to be added to every query that will return more than 1000 results.

  10. support server side aggregation in AFSDK

    I would like to aggregate multiple tag values in a server side operation using naturally scheduled or sampled intervals in some form similar or extending FilteredSummaries.

    Most common case is finding the maximum aggregate of two or more tags.

    It's not practical to rely on Analysis for adhoc use cases.

  12. PI OPC Server 2017 - SDK Aliasing

    With PI OPC DA Server 2017, SDK aliasing is no longer supported. It would be nice to be able to not reconfigure the client's ItemIDs and use an alias after migrating a Data Archive.

  13. Move AF Elements with PI Web API

    Create an additional action under the elements controller that can move an element from one parent to another while removing the child element from the original parent element's hierarchy.

  14. Return row number from PI SQL Client calls

    It would be useful to be able to access a specific row from a PI SQL Client call. For example if I query muiltiple attributes indicating some KPI ordered from highest to lowest returning 1000 rows, I might want to show only the top 10. The TOP function is supported in SQL Client, but the Table Lookup DR in AF only allows you to find the first row.

    It would be useful if either the row number, 1..n, was returned or the table lookup DR would allow you to pick a specific row. This would then allow you to show…

  15. Complete AF SDK documentation

    Include protected (C# syntax) member, for example in data reference documentation. I developed more than 20 data reference plugins with functions not provided by Formula and AF analyses and needed to override some not documented methods of the base class.

  16. afattributesearch expose value timestamp as fields

    Maybe I'm missing it, but after performing an AFAttributeSearch I would like to use the binning extensions for summaries or aggregate periods, much like the EventFrame examples. However the fields exposed by AFAttributeSearch do not include the actual event timestamp.

    Can OSIsoft either update examples on how this is possible (sadly all examples are across eventframes whose search does expose datetime fields in StartTime/EndTime), or enable retrieval of Timestamp as a field for AFAttributeSearch?

  17. Streamsets in form of HTTP POST

    Streamsets controller should have a mirror with http POST calls. It's easier to send data in the body using strongly typed model. (As an example, what if you need to get snapshot values of 1000 pi points). Consider to use POST as a GET in some places where amount of arguments in the url can become an issue.

  18. Expose most of PI-SMT functionalities to AF-SDK

    I have to admit that I am surprised and disappointed not seeing any real good administration methods in the AF-SDK. Of course there is Powershell but what I would really want is a nice way of getting all the information I see in SMT and more within C#. There are so much valuable information we could gather and analyse. We could also automate tasks etc...

  19. "Create or Update Data Reference" through OSIsoft.Powershell

    It is already possible to create an instance of an existing AF Element Template by using the powershell cmdlet Add-AFElement with the -AFElementTemplate option. The element is then created in the AF tree, however if there are tag creation rules defined in the template, the tags are not created until you manually perform an "Create or Update Data Reference" using the PI System Explorer. It should be possible to trigger "Create or Update Data Reference" via Powershell as well, either by an additional option of the Add-AFElement cmdlet or by a separate cmdlet.

  20. PI SQL Commander usability suggestions

    To make things easier for the user, please consider doing the following:
    • Move the contents of View, Query, Tools, and Help from the menu bar into the toolbar. This will reduce the click count from 2 to 1, and the toolbar has more than enough room to accommodate some additional buttons, especially when the window is maximized.
    • Add the keyboard shortcuts to the tooltips of the buttons in the toolbar.
    • Label more of the toolbar buttons so that the user does not have to hover over each button to know what each button does.
    • Eliminate the…
