  1. Add .NET Core support for AF SDK

    Please add support for .NET Core to the AF SDK. Currently only full .NET Framework is supported.

  2. OSIsoft Python Library for data science

    As a data scientist, I would like to be able to use a fully supported OSIsoft Python library without having to directly interface my Python script with a middleware. This OSIsoft Python library would be able to perform the same operations as PI DataLink, but directly in Python. Having this OSIsoft Python library would be beneficial for me because it would greatly improve the time needed to create data analysis scripts and make it a lot easier to interface with 3rd party Python libraries like Pandas for data analysis.

  3. PI Web API should cache Windows Identities when making multiple requests with Claims Based Authentication

    As a PI Web API client, I would like bearer authentication to be more performant. So that I can write secure, responsive client applications

    BearerAuthenticationProvider should cache WindowsIdentity. Currently ClaimsPrincipal is cached and WindowsIdentity is retrieved for each request from C2WTS.

  4. Add support for unit conversion

    Please add a "Canonical UOM Per UOM" or "UOM Per Canonical UOM" column (not necessarily with those exact names) to the UnitOfMeasure table. This column would contain the conversion factor needed to convert between the UOM and the canonical UOM, similar to the "Canonical" column in PI System Explorer when you are viewing a UOM class.

    With this in place, a user can easily convert a value to any unit by first converting from the value's default UOM to the canonical UOM of the value's UOM class, and then convert from the canonical UOM to the desired UOM. This would…

  5. Get AF Server Name and AF Database Name in PI SQL DAS (RTQP)

    As a PI Applications Developer, I need to be able to retrieve the name of the current AF Server and Current AF Database in the PI SQL DAS (RTQP). This information was available in PI OLEDB Enterprise’s [System].[Connection].[ConnectionProperty] and [System].[Connection].[ConnectionStatus] tables. I would like it to be in PI SQL DAS (RTQP) as well.

  6. Provide a PI SQL Commander Lite Standalone Download

    Currently, PI SQL Commander Lite is bundled with PI SQL Client, PI OLEDB Enterprise, and PI ODBC Driver.

    It is a very useful tool for PI OLEDB Provider, which does not bundle it. To use it, another provider needs to be installed to obtain PI SQL Commander Lite indirectly.

    The version of PI SQL Commander Lite that is bundled with each provider is the latest version of PI SQL Commander Lite at the time of the provider's release. This means that the latest versions of each provider could have different versions of PI SQL Commander Lite bundled with them.

    Manageability…

  7. Allow adding one AFEnumerationSet to a different PIServer

    If you run

    pIServer.StateSets.Add(aFEnumerationSet);
    afEnumerationSet.CheckIn();

    The set will not be checked in if the PIServer of the AFEnumerationSet is not the same as the PIServer you are checking into.

    Instead you have to do:

    AFEnumerationSet newSet = new AFEnumerationSet(setToCopy.Name);
    foreach (AFEnumerationValue aFEnumerationValue in setToCopy) newSet.Add(aFEnumerationValue); destinationSets.Add(newSet);
    setToCopy.CheckIn();

    Please automate that functionality.

  8. Implement Attribute Trait filtering for AFSearch

    I would like to perform AF Searches that return results based on Attribute trait filtering. More specifically, I would like to search for Elements that contain Location trait Attributes, so I can query more easily for assets that have a Location trait. I currently rely on Element Categories or Element Template filtering, but those filters do not always match the search results I am looking for.

  9. Allow to change Connection Default Preference for all AF SDK applications

    If the user wants his custom applications running on a particular client machine to connect to the secondary server of a collective, he could of course hard-code that. But that becomes impractical if there are a lot of custom programs or they are deployed on several client machines, some of which he might prefer to connect to the primary. It would be more flexible if there was some global setting to control this.

    The first thing to do is to change priorities for the primary and secondary by assigning the former a bigger number. This can already be done in…

  12. Improve error logging when PI Web API fails to load attributes that are not marked as configuration items

    As a PI Web API administrator, I would like to see errors logged when PI Web API fails to load any attributes because they are not marked as configuration items. This will decrease required troubleshooting for these issues.

  13. 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.

  14. 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.

  15. 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.

  16. Sort list of tags returned by AF SDK's FindPIPoints() method

    Add a method that can be used to sort the IEnumerable<PIPoints> returned by AFSDK's FindPIPoints() method. This method should allow the option of sorting on any desired PI Point Attribute.

  17. 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…

  18. 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…

  19. 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."

  20. 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.
