  1. Windows authentication of clients

    As a PI user, I want the OPC DA and HDA Servers to honor the Windows identity of any connected OPC client.

    We understand the requirement. It makes sense. We have been looking into it but it turns out to be difficult to do. We used a third-party framework to build the PI OPC DA Server which separates interactions with the OPC client from interactions with the PI Data Archive. It solved a number of problems but unfortunately there is no easy way to have OPC client user credentials flow to the PI Data Archive. We are evaluating our options.

  2. Support DST Transition on Second Granularity in PI SDK

    A user tries to retrieve date with timestamp 03-Nov-2018 23:59:59 (1 second before Daylight Saving Time beginning) in PI SMT, but the returned event has a timestamp of 04-Nov-2018 00:59:59. This is because PISDK timezone design is such that it can only transition DST on minute granularity, and the Windows TZ info for Brazil says the transition is at 23:59:59 so PISDK truncates the seconds for the transition rule.

  3. 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

  4. Provide programmatic interface to manage OMF applications

    Enable Create,Read, Update, Delete operations for OMF applications via an API so that the process is standardized and efficient/effective as opposed to manual and error prone, especially for larger numbers of apps.

  5. AF SDK and Web API on Linux OS'es

    With Microsoft supporting .NET Core on Linux operating systems such as RHEL, SLES Ubuntu, CentOS, and Debian.
    https://docs.microsoft.com/en-us/dotnet/core/about
    https://docs.microsoft.com/en-us/dotnet/core/linux-prerequisites?tabs=netcore2x

    They are even supporting SQL Server on Linux OS'es.

    I don't know the dependencies of the AF SDK nor the Web API, but if they can use .NET Core; it would be nice to have the AF SDK and Web API available for Linux based OS'es.

  6. Schedule PI Web API Crawls

    The customer would like the ability to schedule crawls for a specific AF database (it's quite large), so that crawls don't interrupt users who need to access the elements in the PI Vision search during their working hours.

  7. 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.

  8. 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.

  9. 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.

  10. 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

  12. 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.

  14. 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.

  15. 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 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.

  20. Allow PI Web API to access the AFPort Class

    Customer is referring to the AF Elements Ports that can be seen with PSE and are implemented in AF SDK in AFPort class.
     
    Customer wants to access to the same features with PI Web API, which is currently not possible. Customer wants to know are there alternative options? Or will it be implemented in Web API in the future?
