  1. Add in the Element Hierarchy table information to determine the primary reference of a copied reference element

    When an element is copied as reference (parent-child) elsewhere in the tree it then has multiple parents. One of it is the primary parent. This information needs to be added to the hierarchy tables.

    PLANNED  ·  Christopher Manhard responded

    This is planned for the 2018 R2 release for AF based searches. Note that while the user interface in PSE will allow OR clauses to be typed in, there will not yet be a user interface in 2018 R2 to help you build OR clauses.

  3. 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.

  4. 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…

  5. Streamsets in form of HTTP POST

    Streamsets controller should have a mirror with http POST calls. It's easier to send data in the body using strongly typed model. (As an example, what if you need to get snapshot values of 1000 pi points). Consider to use POST as a GET in some places where amount of arguments in the url can become an issue.

  7. PI AF SDK Linux Support

    As we know there are 2 major competitor for cloud technologies that is Microsoft and Linux destros. If we want to use Linux docker image or PCF Linux image to connect AF SDK, we don't have any provision for this as of now because AF SDK does not support Linux OS. If we support this then most of cloud customer attracts to use AF SDK in their organization.

  8. Add support for AFElement Versions

    Add support for AFElement versions to PI Web API.
    1. Create a new Element Version by defining the effective date and an optional version comment. 2. Add Get and Find methods which support querying AFElements by setting a QueryDate.

  9. Return Partial Results From Event Frame Search in PI Web API

    Currently when searching for event frames, a 400 error is returned if not all elements in the search exist.

    piwebapi/eventFrames/search?databaseWebId=WebId&Element:IN("\server\AssetSwap\Site2\Asset1";"\server\AssetSwap\Site2\Asset2"

    This is cumbersome especially in the case of asset swapping in PI Vision when parent elements could contain variable child elements. For any parent element that contains less than the max child elements, a 400 error will occur when searching for event frames for related parent elements.

  10. 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.

  11. Get Values by Count in the PI Web API

    As a PI Web API developer, I would like to retrieve values by specifying a count like you can do in PI SMT and other PI clients. This functionality is exposed by the RecordedValuesByCount in the AF SDK.

  12. Add the “Create Timestamps” functionality back into the OPC DA Server product

    In the PI OPC DA/HDA Server 2010 product, there was a “Create Timestamps” functionality (found in the OPCServerConfig Tool). This option had the PI OPC Server create timestamps for OPC clients. I rely on this functionality heavily for an OPC client I use every day. Thus, currently I have to stay on PI OPC DA/HDA Server 2010 since this functionality was removed from the newer version. I would like to have this functionality back.

    We understand this feature is important and we are planning to restore it. We will give you an update on the release schedule when this is finalized.

  13. 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?

  14. 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.

  15. 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.

  16. 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."

  17. 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.

  18. 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.

  19. 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

  20. Expose Event Frame Extended Properties in PI SQL Framework

    As a PI SQL Framework end user, I need to be able to distinguish between event frames generated by PI Batch Interfaces from different sites or data sources by filtering my query on the name of an event frame extended property.
    PI Batch Interfaces store the unique ID of the data source as the name of an extended property in the event frames they generate. When multiple PI Batch Interfaces write to the same AF Database, the extended property name can be used to distinguish between event frames from different data sources or sites.
