  1. 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.

    Apologies as I meant to set this item to declined with my previous update.

    Thank you for your valuable feedback. We have no plans to work on this feature in the near future, so I am setting the status to declined. I will update the status if we eventually schedule this work.

  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. 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.

  5. Return Elements with Bad Values with AFSearch

    As a programmer, I would like to search for and return elements with attributes that contain bad values  using the AFElementSearch Class in the AF SDK.

  6. 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.

  7. Allow decimal representations of days, months, and years in time strings

    PI Time offsets only allow for integer numbers of days, months, and years. For example, -1d is allowed, but -1.5d is not. Hours, minutes, and seconds allow decimals. There are a number of client tool situations where the customer would like to offset by a decimal number of days; in these cases, they will need to convert to hours before proceeding.

    We cannot use fractions in many cases due to variability. For example, DST, leap year, # of days in a month, etc.

    From our documentation for AFTimeSpan.Add:
    “Intervals year, month, and day do not allow fractions because they are variable length. For example, adding a fraction of a month would require choosing between a month containing 28, 29, 30, or 31 days.”

  8. Use Escape Sequences with ODBC driver

    ODBC driver should support the use of Escape Sequences such as {ts}

  9. 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.

  10. 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.

  12. Commit to combining PI Web API and PI AF SDK

    By my understanding, PI Web API is cross-platform but is slower than and lacks some of the features of PI AF SDK. Over time, PI Web API's speed and feature set approach those of PI AF SDK, making platform compatibility a progressively more significant difference where PI Web API wins out. The writing is on the wall but no one is saying anything.

    Please officially commit bringing the speed and features of PI AF SDK into PI Web API so that PI Web API is the only API that developers use, and then PI AF SDK can be deprecated. This…

    PI Web API is based on the AF SDK, so deprecating the AF SDK is not a viable option.

    That being said, what specific capabilities are you looking for to enhance the PI Web API?

  13. 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…

  15. PI ODBC driver for linus

    There is a pi JDBC driver for linux, but not an ODBC driver. This means that tools built around ODBC do not fully exploit the tools functionality. For example, RStudio has great database navigation tools that require ODBC.

    We have reviewed this idea, and it’s not something we plan to implement at this time. Even though we are declining this idea for now, it is still open to comments. We do want to hear your opinion. Thank you for the feedback, and please, keep sharing!

  17. Have Status of an analysis

    I would like to have status of analysis (Enabled, Disabled, Running, Error or Warning) via PI AF SDK with the attribute 'Status' or the method 'GetStatus'.
    In the library, we already have in AFStatus all the Status declared but not used.

    Thanks to that it will be possible to see all analysis in error and try to resolve analysis in error with AF SDK.
    Morever, We won't do backfilling on analysis in error and create other error, it will be clean to do backfilling on all analysis Enabled if we know which analysis are in error.

    Sorry for my english…

  20. Configurable message sizes for PI Channels

    See https://pisquare.osisoft.com/message/112944-is-there-a-way-to-limit-the-size-of-pi-channel-messages for the originating question.

    Clients connecting via PI Channels have limits on the size of messages they can receive, for security reasons.  It is possible for PI Channel message sizes to exceed these limits.  There should be a way to configure the max message size for PI Channels.
