  1. Develop an interactive INI editor for the UFL Connector

    The editor should allow you to see in real time how it interacts with the data. Being able to test the INI file prior to loading some file would make it much more manageable to read a variety of data format and insure that it has the expected behavior before starting the connector and having to use a trial and error approach. A good example of this is what Microsoft does with PowerQuery in PowerBI. This would allow troubleshooting UFL issues much more easily and allow more people to use the connector without having to spend a serious amount of…

  2. Feature to turn off auto creation of PI Tags in PI Connector for UFL

    Ability to turn off auto creation of PI tags - When data is sent via REST to a PI Connector for UFL service ,currently it looks for a PI Tag in the PI Server and if the PI Tag does not exist it creates a new PI Tag. It would be good if we could turn off the feature if not required as in our case we have a naming convention for PI Tags and we create the tag names in advance so would not like to allow for the auto creation of PI Tags.

    I’m not sure why this would be needed. In the UFL connector you need to specify the name of the tag that you write to. And if that tag already exists, it will write to it. If that tag does not exist, then the connector would create that tag with your desired tag name. Why would you want the connector not to create that tag?

  3. Support passing dynamic timestamps to REST API URI

    In order to retrieve Forecast data from a REST API, I would like to be able to pass timestamps from the Connector dynamically into the URI. For example:
    ...rest/forecast.wsgi?type=hourly&start=2017-02-15T13%3A44%3A44Z&end=2017-02-30T13%3A44%3A44Z&SID=PDX

  4. Connector (UFL) can read AF data structure

    Right now it is a limitation because of the current functionality / design.

    In the future it would be nice if:
    - the connector can read the existing AF structure
    - update the existing AF structure
    - create elements / EF / attributes under existing elements

    there was a case, while the customer wanted to create EF StoreEventFrame() under existing element, but it did not work.

    had to explain the limitation: we are not able to do it unless the element was not created by the UFL.

    also Event Frames StoreElement() needs to be used in conjunction with StoreEventFrame() and…

  5. Allow the UFL Connector to performa a scan Immediately after startup

    On startup, the Connector currently waits for the configured scan frequency time to pass before doing its first scan. There are cases where a low scan frequency (e.g. once per day) is required. This results in an unnecessary delay before the Connector starts collecting data. Please all ow the option to perform a scan immediately after the Connector finishes its internal startup routine.

  6. UFL Timezone Conversion

    Supported timestamps are currently limited to Local or UTC timezones.

    Data sources may not be configurable to provide timestamps in supported formats.

    There currently exists no robust or simple way of converting between timezones using the UFL syntax or configuration.  Including custom daylight savings time logic in ini files for this is not a maintainable solution. DST rules change over time and vary from region to region.

    With the current limitations I am currently having to maintain more than 20 ini files with custom DST logic for our global operations.

    Including functionality to accommodate for the timezone formatting limitations of…

  8. Make the UFL Connector logic development/testing/debugging process less tedious

    Deploying a UFL Connector solution requires a LOT of edits of the INI file as part of the development/testing/debugging process. After each INI file change and file save, the required procedure is as follows:
    1. Click on the Data Source List link.
    2. Click on ‘See Configuration’.
    3. Click on the ‘Change’ button.
    4. Click on the ‘Browse…’ button.
    5. Double-click on the INI file.
    6. Scroll the page down until the ‘Save’ button is visible (I’m using a 1920 x 1080 monitor).
    7. Press the ‘Save’ button.
    8. Click on the ‘Overview’ link.
    9. Press the ‘Start connector’ button.

  9. Create/Write to Child Attributes

    I would like to be able to write to Child attributes with the UFL connector using the StoreInElement function. Currently, it seems that the Connector cannot write to or create an attribute with a path like:

    ..\Element|ParentAttribute|ChildAttribute

    It ends up creating another Attribute at the level of the ParentAttribute with %18i inserted in the name where the second pipe would go. (i.e. the attribute is named ParentAttribute%18iChildAttribute)

  10. Enable setting tag attributes in UFL Connector

    UFL Connector should have ways to set tag attributes. There should be way to set the default compression and exception settings and also other tag attributes like point and data security.

  11. Create child Event Frames

    UFL connector can create child element using StoreElement function.
    it should be useful to extend functionality to event frames on function StoreEventFrame

  12. Add scan time offset option to UFL Connector

    Use case: The UFL Connector needs to read a huge data set from a REST Server which is updated once a day. The only way to control when the data fetch occurs is by starting the connector at the desired time. The Connector however currently waits for the configured scan frequency time to pass before doing its first scan after starting. Furthermore, the Connector/hosting server may be restarted throughout the day for various reasons (e.g. application of Windows patches) throwing the timing off and further adding another 24 hour delay.

    Scanning, processing and sending to PI the same data more…

  13. Enable or Disable single DataSource

    When a datasource is actually offline and we don't want the UFL connector to keep trying uploading or connecting to it and pollute the message log .

    The best option would be having the stop/start enable/disable and restart options for each datasource.

  14. Support HTTP Token Authentication to a REST Endpoint

    The REST endpoint from which I want to pull data requires token authentication. I would like the UFL Connector to be able to obtain the token given the username and password I enter on the Admin page.

  15. Windows Authentication to the Rest Endpoint should be supported with PI UFL Connector. Currently only Basic is supported

    I tried connecting to a REST endpoint using PI UFL Connector. However, it seems the Connector only supports Basic Authentication. The REST point only supports Windows Integrated Security. We can use Web Browser to read data from the REST endpoint. We get the following error in the connector log: HTTP status code: Unauthorized

    Thank you for reaching out. We can extend the connector to support the NTLM authentication, which falls under Windows Authentication. Would it meet your needs?

  16. Add the ability to write to a point using an attribute other than tag name

    Provide the capabilities of mapping a UFL data point to a PI tag using a PI Point attribute other than the tag name.  For example, we’ll have a data file from another database that uses a different ID than our PI point name. Could we write to PI using that ID as the point instrumenttag or exdesc?

  17. Add a Boolean data type

    Boolean variables are useful for reusing Boolean (sub)expressions, concise debugging of the value of a Boolean expression, and extraction and storage of Boolean values before writing to Int32 PI status tags (e.g. on/off status, open/closed status).

  18. Scan only when the data folder changes

    Specifying the scan time seems unnecessary. Instead, the PI Connector for UFL should only scan the data folder if a change to the data folder's contents is detected. Surely some sort of event listener can be set up to achieve this?

  19. Be able to modify the PI Point prefix from the PI Connector for UFL administration page

    It does not make sense that edits to some of the PI Connector for UFL's JSON files can be done through the administration page, but not all. The administration page should be a 1-stop configuration shop.

  20. Configurable OSIsoft\PI Connectors\UFL.ConnectorHost\ location defined during installation

    Currently, the folder is created by default in %ProgramData%, which means that the output folder, storing the processed file, is created in %ProgramData%\OSIsoft\PI Connectors\UFL.ConnectorHost\Output\{DSName}\.
    Since %ProgramData% is generally on the OS drive (C:\), processing a large number of files can cause serious damage to the machine.

    The path can be configured in Global configuration - parameter "Output Path" using the provided PS script that comes with the connector, but this parameter should be configurable during the installation.
