  1. 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?

  2. Make Data Persistence Settings Configurable

    Currently, .zip folders containing processed files can reach up to 256MB in size. Browsing the contents these folders can be difficult due to the number of files within.

    Being able to specify either a file count of folder size parameter would help simplify this process by breaking the zipped folders into more digestible, user configurable sizes.

  3. Allow UFL Connector to show status when HTTP request fails

    This enhancement would allow the UFL Connector to be able to write a status to it's tags when a HTTP request fails, such as 401 or 503. 

    Currently, a bad HTTP request will fail before attempting to parse with the .ini, so  there is no way to control this behavior via the .ini.

  4. 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?

  5. 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.

  6. 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?

  7. Make a version of SkipFile() that stops processing the current file immediately

    The current SkipFile() function tells the PI Connector for UFL to skip the remaining lines in the file, but the PI Connector for UFL will continue to execute the rest of the code in the "per message" section that the current line triggered.

    Please consider making a version of SkipFile() that stops processing the current file immediately. This helps avoid unnecessary Else blocks in If statements. This functionality would be similar to returning from a function or breaking out of a loop in other programming languages.

    To implement this, consider adding a new function or adding a function argument SkipFile().

  8. 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)

  9. 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.

  10. 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).

  11. 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…

  12. Allow overriding of point and data security newly created points

    As a PI Admin, I want to specify my desired point and data security in the UFL configuration files for the new tags that the connector creates. I want to be able to set this on an instance by instance basis to override the inheritance from the PIPOINT table. This would be similar to the functionality that already is implemented in the Batch Framework interfaces.

  13. Allow the connector to use a proxy for web requests

    Provide a way to configure the connector to use a proxy and authenticate with the proxy if required.

  14. Add a type casting function or operator

    The INI files would be shorter and more readable if the PI Connector for UFL had a type casting function or operator.

    For example, if you are incrementing a Counter variable (type Int32) for each data line, and your tag names are Tag1, Tag2, etc., you currently cannot simply save data to "Tag" & Counter. You must assign Counter to CounterString (type String), and then save data to "Tag" & CounterString.

    This could be simplified to "Tag" & CAST(Counter, "String") or "Tag" & (String)Counter. A type casting function or operator would avoid the intermediate variable while still making it clear…

  15. Incoming TimeStamps Utc

    Please rename "Incoming TimeStamps" to "Incoming Timestamps".
    Please change "Utc" to "UTC".

    These small spelling issues come across as sloppy.

  16. Use a consistent language-region separator for Locale

    Currently, the language-region separator in the Locale choices can be any of "-" (hyphen-minus), "–" (en dash), or ":" (colon). For consistency, please use only 1 separator.

  17. Use the most recently used Locale as the default

    The default Locale is currently "English - United States" for all new data sources. Please consider using "English - United States" as the default Locale only for the 1st data source, and using the most recently used Locale as the default for all subsequent data sources. This saves the user from repetitive Locale configuration.

  18. "13,10 OR 10" New Line default

    Currently, there is no default entry for New Line. The user can use any characters as line delimiters, but the Windows and Unix new lines would, by far, be the most common. Please make the default New Line "13,10 OR 10" to save most users the trouble of configuring the New Line.

  19. Make CONCAT take an arbitrary number of arguments

    Currently, CONCAT only takes 2 arguments, so you need to nest multiple CONCAT (or just use the & operator) if you want to concatenate multiple strings. This can be avoided if CONCAT could take any number of strings as arguments.

    In general, users expect associative functions to take an arbitrary number of arguments.
