  1. Datalink - Root Path should allow to specify multiple Data Archives

    Currently, the Root Path field of Datalink can be pointed to a single cell to retrieve the name of the Data Archive where the tag resides.

    It is not possible to specify an array of cells, as only the first Data Archive will be considered.

    There are workarounds for this, such as:
    - using an Excel formula to concatenate the root path and the point name and call the obtained cell from the DataItem field
    - using single-row queries instead of array queries

    Still, it would be nice to have an array-query option also for the Root Path field.

  2. Resize all PI DataLink array formulas in the selected range

    Currently, you can only use "Recalculate (Resize) Function" on a single array formula at a time.

    Instead, please consider implementing this rule: all PI DataLink array formulas that have ≥1 cell in the selected range get recalculated and resized.

  3. Programmatically Change Datalink Settings

    Because Datalink always uses the default settings when run like a service, it'll be nice to have a programmatic way to access the Datalink settings

  4. PI DataLink service for PI Server

    To minimize the amount of data that is returned from the PI Servers, and to make the PI DataLink computers more like thin clients, consider making a service for the PI Servers (PI Data Archive + PI Asset Framework) that handles PI DataLink requests.

    This service should perform all interpolation calculations (Sampled Data) and aggregation calculations (Calculated Data) and return only the raw function output to PI DataLink.

  5. Include Option to Install Legacy Add-Ins Via Installation Wizard

    Many users utilize the legacy add-ins for DataLink through VBA code.  Starting with DataLink 2016, the add-ins are not installed by default and so upgrades and new installations can prevent existing spreadsheets from working if additional steps were not taking to install the legacy components.  These steps are unnecessarily complicated: extract the installation package, modify the setup.ini, then proceed with the installation.

    Instead, the installation wizard could provide users with an option to install the legacy components while at the same time warning them of the security risks posed by ActiveX.

  6. Allow case-sensitive filtering on PI Point Value in Search Dialog

    PI DataLink 2017 added the ability to filter searches based on a PI Point's current value.   For searching on PI Point's with string values, it would be great if there was a way to do a case-sensitive search.  A ‘case-sensitive’ checkbox would be useful (so you could toggle it on/off).

  7. Add AFTimestampCalculation options to Calculated Data

    PI DataLink currently uses Auto to return the timestamp.  As a power user, I would like to be able to choose between Auto, EarliestTime, and MostRecentTime for the timestamp returned for a value when a summary calculation is done.

  8. Add Population Standard Deviation to Calculated Data as a calculation mode

    As an end user, I would like to retrieve the population standard deviation in PI DataLink.  This option is available in the AFSummaryTypes enumeration:

  10. Eliminate the "calculation basis" argument for Calculated Data

    Consider eliminating the "calculation basis" argument (time-weighted versus event-weighted) for Calculated Data.

    Reasons:

    • Average already has 2 calculation modes, 1 for each calculation basis.
    • Minimum, maximum, and range produce the same value whether they are time-weighted or event-weighted.
    • Time-weighted count is useless and so is not needed.
    • Time-weighted total (i.e. integration over time) and event-weighted total are not even in the same dimension, since integration over time multiplies the unit by time, but an event-weighted total does not. These should be separated into 2 calculation modes. Consider calling the time-weighted total something like "totalize" or "integral"…

  11. Display a parameter tooltip when typing functions manually

    Please add a tooltip or equivalent to show the arguments of the PI DataLink functions when you are entering the functions manually, similar to the tooltips that appear when you use native Excel functions.

  12. Add a unit column for data item searches

    In data item searches, it would be useful to have a column that shows the engineering unit or default UOM of the returned results. This helps assure the user that they chose the correct data item and confirms the data item's unit with the user.

  13. Percent questionable in PI DataLink

    Add an option for PI DataLink functions (such as Calculated and Sampled data) to show "Percent Questionable" similar to the option available now for calculating "Percent Good".

  14. Support for relative column display

    Datalink 2015 and above supports cell reference but not relative cell reference.

    For example:

    If column A has tag names and you want to query archive value,

    functions with cell reference work:

    =PIArcVal(Sheet!$A$1,"*",0,"","auto")
    =PIArcVal(Sheet!$A$1:$A$4,"*",0,"","auto")

    however function with relative cell reference does not work:

    =PIArcVal(Sheet!A:A,"*",0,"","auto")

    Relative cell reference used to work up until Datalink 2014 which is breaking existing reports on updating Datalink.

  16. Allow user to independently filter on attribute name and element name in search dialog

    Currently, the same filter used in the search term text field when searching on an AF Database.    The user would like to be able to use independent filters on the attribute name and element name so that they can filter down their search results.

  17. In the Asset Filter Search task pane, add the ability to filter attributes shown in "Attributes to display" list

    The "Attributes to display" list becomes difficult to navigate when a large number of attributes are present.   A filter would be helpful.

  18. Allow user to set preferred point attribute filters for PI Data Archive Search

    In the search dialog, the user has the option of filtering by many point attribute filters; however, customers may prefer some over others.   Perhaps the filters preferred by the user could be preserved across user sessions.
