  2. Support importing multiple aliases using the KST.INI file during setup

    As a PI System Admin, I would like to be able to specify multiple aliases for one PI Server in a KST.INI file that will be used to create a predefined set of PI Servers during a silent install of the PI SDK so that I can ensure that all users have the same KST that includes multiple servers with multiple aliases for each server. This is more efficient than installing the PI SDK and then having to push a registry update.

  3. Create a utility/script that will output the PI products installed, their versions and the most recent version of the product

    Create a utility/script that will output the PI products installed, their versions and the most recent version of the product on the machine it is run on. This would help with installations and to manage the current software that is installed.

  4. Add data reference impersonation for value retrievals

    When retrieving values for attributes, impersonating the user can enable the user of security at the data source level. For example, with a PI Point Data Reference attribute, it could allow the user's authorization to be user at the data archive rather than the PI SQL DAS (RTQP) service account doing the data retrieval.

  5. Have an option for the PIPointList.RecordedValues Method to exclude the current value if now (*) is specified as the end time

    With the PIPointList.RecordedValues Method, using an end time of * will include the current value. This is unexpected when the method "Returns a list of compressed values for the requested time range from PI."

  6. Add an action to StreamSets controller to register for updates at element or event frame

    Adding another action in the StreamSets Controller to Register for StreamSet updates in the form POST streamsets/{WebId}/updates with WebId referring a parent object like an Element or EventFrame would be really helpful to get updates for all attributes that belong to an element, similar to Channel controller behavior.

  7. Include overridden attributes of derived templates in Event Frame View with PI SQL DAS (RTQP)

    When you create a template-specific event view, event frames based on derived templates are also returned. However, attributes which are overridden in the derived template return empty. This means more complicated queries using UNION ALL must be used.

    As a user, when I use a derived template with an overridden attribute, it is often because I need to change the way that attribute is calculated in a subset of cases. However, I still want to be able to create a view easily for all of this data.

    For example, I have a "Batch" template with "Pounds Produced". However, for a…

  8. Be able to use RTQP to access PI Points and Config strings (DA Directly)

    Be able to use RTQP to access PI Points and Config strings (DA Directly)
    Use case:
    create a dashboard that lets me know the amount of bad data (tags) mapped to our AF.

    (eg. “Bad Input”, “Calc Failed”, etc)

    Our system has numerous tags and it is impossible to monitor them one by one.

    The RTQP engine has allowed us to query massive amount of AF Attributes to get their current values easily.

    Some AF attributes have been excluded in our system. For that case, we are not interested whether or not the values are bad.

    Hence I would like…

  9. Enable PI Web API to retrieve previous AF Tables versions

    Internal AF table has been updated using AF versioning system, however retrieving it whole with PI Web API only works for current version: GetData method from Table controller (GET tables/{webId}/data) does not accept a time parameter.
    Workarounds involve creating Table Lookup Data Reference attributes or joining all table versions adding columns for time range to be later filtered out.

  10. Add More PI Web API Indexed Search Crawler Scan Interval Options

    As a PI Web API Indexed Search Crawler Administrator, I would like there to be more pre-defined scan intervals available in the piwebapi/admin/search/settings.html page to lower the granularity of the jumps between scan intervals available.

  11. PI WEB API - Swagger page

    It would be great if as an addition to conventional documentation there was a SWAGGER page with short explanation of methods and parameters (including return types, etc.)

  12. Provide ability to specify ID (Guid) when creating elements or attributes

    Provide ability to specify ID (Guid) when creating elements or attributes in AF via the AF SDK.

    When replicating data from an external system to AF, we need to be able to use the same GUID that has already been established.  This will allow us to easily query data from PI Web API because the GUIDs can be directly translated into WebIDs without having to perform lookup queries first.

  13. Allow Searching of PI Points by PointID or Crawling of the PointID attribute

  14. PI Web API should allow the user to configure personally identifiable information (PII) to be shown in logs

    PI Web API 2019 now hides personally identifiable information (PII) in log files. As a PI Web API Administrator, I would like to be able to configure PI Web API to show personally identifiable information in log files, so that it is easier for me to troubleshoot Bearer Authentication issues.

  16. Allow editing of the PI OPC DA Server ItemID

    The ItemID of PI tags retrieved using the PI OPC DA Server has a backslash. In order to maintain consistency with browsing for OPC tags on their client, is there a way to remove or replace the backslash in the ItemID? For example, <servername>.sinusoid instead of <servername>/sinusoid

  17. PI SQL Client to make use of the RecordedValue method and Retrieval Modes for the GetValue transposed function

    When making use of the GetValue transposed function when creating a new Template specific Data Model, we can see that under the hood it makes us of the AF SDK call AFData.InterpolatedValue method to capture the data at a specified timestamp provided in the transposed function. This method does make use of any Retrieval Modes.

    It would be good for this GetValue transposed function to make use under the hood of the AF SDK call AFData.RecordedValue method instead since this method offers the possibility of using Retrieval Modes like "AtOrBefore" which is really useful to capture the last archived value…

  19. omf endpoint: override type uom in container messages

    OMF 1.2 specification includes an enhancement to allow the use of propertyoverrides keyword in container messages.
    Request is to add this functionality to Web API OMF endpoint specifically for the uom property

    For example:
    1. device configured with uom, OMF application creates a type specifying that uom.
    2 new version of the device changes the uom. OMF application needs to create containers with the new uom, retaining other properties of the type.

  20. 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…
