  1. Event Frame Re-capture/Backfill Option to Save Annotations/Reasons

    When a backfill or "recapture events" option is selected for Event Frames, give the user an option to "Save Annotations" for that specific event frame. Right now, we use Event Frames to copy in Reason Codes and Comments (that are logged as annotations) so we are limited in backfill or recapturing the data if historical data changes.

  2. Outputs at close available for all generation modes

    ‘Outputs at close’ is very powerful and flexible. It allows one to use expression analysis syntax in event frames. Unfortunately, it is only available for generation mode 'explicit trigger', but not for 'pulse', 'step', or 'step continuous'.

    If you want e.g. a new event frame started every time a value of an input tag changes (and closed again when it changes again), generation mode step continuous is what you need.
    In that case it would be very helpful to also be able to use outputs at close.

  3. PI Data Archive - import tags and merge historic archives together

    As a customer who is moving their PI Data Archive historic data to a Centralized IT Facility, hosting another PI Data Archive, and that would like to import tags and historic data from another PI Data Archive, it would be great to have a functionality on PI Archive Subsystem and PI System Management Tools that allow to import PI Points and their historic data to the centralized PI Data Archive without having to perform all the steps for the Merge procedure.

    Another option would be to have an improved PI Base, Snapshot and Archive Subsystem services, that allow to have…

  4. Add the ability to specify NULL values in manually created AF Tables

    When manually creating an AF Table (i.e., an internal AF table) in PI System Explorer having the ability to specify a NULL value would be beneficial. Not all datasets require a value for each cell and not all tables need to be linked to, or imported from, external systems.

  5. Trilinear Interpolation

    The ability to utilize three columns as input for interpolation from an AF Lookup Table to determine the result for a fourth column could be beneficial for predictions and analysis.

    Currently, only linear and bilinear interpolation is possible from an AF Table Lookup.

  6. AF/Analysis Number Base Conversion Functions

    There are no number base conversion functions available in AF Analysis. There are many situations where I need to convert numbers between different 'number bases'. I frequently work with MODBUS devices and there are many times number base conversions are needed to properly get data.

    Example: Convert decimal to hex, hex to binary, etc.

    I test many of my functions using Excel before implementing them in Analysis. Excel has functions such as HEX2BIN, DEC2HEX, etc. I'm actually surprised that, after many years of AF/Analysis development, these type functions are not available. These are valuable functions that should be implemented.

  7. Function to extract Data Reference Type

    We would like to be able to extract the data reference type (PI Point, None, Formula, Table Lookup, etc.) for an attribute using PI Analysis, similar to the TagType function for PI points.

  8. PI Tag Renaming Detection for PI Vision/PE Calculations

    When input PI Tags are referenced in PI Vision 2020+ calculations, they do not automatically detect PI Tag name changes. For users with a lot of calculations, this can be extremely problematic in the event of a PI Tag name change. In the event of a name change, the following error is produced: [-12301] Performance Equation parsing error. Possibly updating the PE scheduler to reference the PointID instead would be beneficial.

  10. Use different Windows account for linked table authentication

    As a user, I want to have the option of entering a service account's Windows credentials when authenticating to a Table Connection in PI System Explorer. Currently, the Windows authentication mode only allows impersonation of the user running PI System Explorer.

  11. follow Display Digits on the PSE Pop-up Trends

    large value display as 1.23 E+008 format instead of the orginal value in PSE Pop-up Trends

  12. Add support for multi-dimensional array parameters in SOAP delivery endpoints

    Currently, while the UI can recognize parameter types as multi-dimensional arrays, the configuration UI for a Notification Rule does not allow access beyond the first array dimension.

    It would be useful to have full support for parameters configured as multi-dimensional arrays (i.e "MyType[][]") in addition to the exsisting support for 1-dimensional arrays ("MyType[]")

  13. Connect PI AF to Industry-standard physical properties databases

    Can PI AF be connected to physical properties databases (libraries) such as AIChE Dippr or Aveva Thermo or others in order to programmatically call for physical properties data in realtime. (Centralize calcs in AF)

  14. Allow AF to use any PI Point metadata (descriptor, UoM, Compression, etc.) as Attributes.

    Some metadata can be used in Analyses, which is helpful, but means constantly running an analysis on static data in order to use it at all in AF, which is inefficient, and we have been told to pull in data as a linked table into AF, which seems unnecessary as the data already exists in the PI environment.

    Please allow us to pull in metadata as Attributes in AF, which then makes things much easier to view, check for accuracy, and update, using all of the extra capabilities of AF which are much more robust and easier to use than…

  15. Customized PI System Explorer view

    Currently PI System Explorer views lots of stuff that is not used by most users (ports, models etc.) also, there are some things that may depend on decisions of particular client - for example, I don't want my users to use Formulas.
    I suggest to provide way to either customise PI System Explorer on each client (choose which part of Explorer is visible, which not - this seems to be a easier way to implement) or move that config to AF server so that every instance of PI System Explorer shows only that content which is allowed on connected AF…

  16. Add filtering and rolling log system to AFGetTrace

    When troubleshooting intermittent issues, using AFGetTrace may be problematic as the trace can consume quite a bit of disk space, and setting a maximum file size will cause the trace to stop once the file is full. Without knowledge of when the issue will reoccur, we are stuck either risking filling up the disk and having a huge trace file to analyze, or set a max file size and possibly miss the issue.

  17. Add the ability to display UOMs in different languages in the PI AF Client

    Automatically display UOMs in the PI AF client in the language of your choice i.e. not a conversion of units. For example, to change the display of UOMs to Russian instead of English, kg becomes кг, V becomes B.

  18. Polybase Support with PI SQL Client

    Creating a Polybase External Table with a PI SQL Client connection via ODBC causes query errors showing only it only supports column-wise binding. Polybase attempts to utilize row-wise binding which is not supported. Developers and customers have shown that Polybase is unable to be instructed to utilize column-wise binding instead.

    When querying against an External Polybase Table the following errors are shown:
    Function "SQLSetStmtAttr(0x2485bf85640, 5, 0x1d1f, 0)" was called.

    Function "SQLSetStmtAttr" exited with an error code -1.

    Error: [PI SQL Client] Only 'SQLBINDBY_COLUMN' is supported.

  19. Colour Data field in AF Attribute

    We are creating hundreds of different attributes in AF, mostly based on templates and using these in PIVision.

    One thing that is annoying is when you make the PIVision image you have to manually change the colour of the symbol you use/trend you created etc to reflect the medium of the attribute that is used. Sometimes you even have to change the HEX colour code since it does not match the standard colour palette.

    What I am suggesting is to have a Colour Datafield in System Explorer for attributes.

    Here we can define the colour (via HEX code or another…

  20. Ability to retrieve only all top-level Attributes

    In an AF Hierarchy where an element contains dozens of Attributes - each with Child Attributes - I am interested in only bringing back all top-level attributes. The use case is that the top-level attributes may not have any naming convention in common but are all defined as PI tags (Child attributes may or not be PI tags). I would like to just bring back the top-level attributes in PI Builder so I can quickly modify tags en masse.
