  1. Support AWS RDS SQL Server instances as backend DBs for AF and PI Vision

    Our company is progressively superseding the deployment of hosts with SQL Server installed, while moving towards the usage of SQL Server instances provided by AWS' Relational Database Service as the DB backend. Although currently OSISoft does not officially support the usage of RDS instances as backends for AF and PI Vision, we performed some internal tests with both AF and Vision and they seem to be promising. We would like OSISoft to study this kind of solution and, if there are no major obstructions, provide official support for such scenarios.

  2. Allow nested operations in AF Asset Analytic functions for 'attribute attname'

    KB00868 recommends Asset Analytics as the right job, but there are some major limitations that inhibit ease of use and deployment, specifically around operations on >1 attribute or tag simultaneously.

    To improve this, AF analyses functions that take in data of type "attribute attname" should be able to process an expression that returns type attribute. Perhaps limited to periodic analyses other toggleable somehow, as there is potential to use a lot of CPU cycles.

    == Example 1: Totalized Mass Flow ==
    Given FIT-001 and DIT-002, return the totalized mass flow (say, kg) over an interval. The current process:

  3. Exclude analysis output attributes when the analysis is suspended

    When the PI Analysis service determines an Analysis should be Suspended, it should also set any output Attributes to be Excluded. As the Analysis is Suspended, it will not output any results and if it has always been Suspended, the output Tags will never get created. Excluding the output Attributes will keep the Element looking clean and also allow dependent Analyses to go into a Suspended state instead of throwing an error when they can't find the Tags. Similarly it will prevent other applications (OSIsoft and third parties) from querying the Attributes and also throwing errors, causing performance issues.

    Automatically…

  4. Enhance functionality of NumOfChanges

    By now the NumOfChanges Function in AF Analytics does not take into account the value at the start of the timerange. NumOfChanges only counts the amount of changed values of the recorded values in the given timeframe.
    If I query the NumOfChanges for today 12 am till now and my Archived Values are:
    Val1, 11:59 pm (day before)
    Val 2, 4 am
    Val 2, 12 pm
    Val 2, 8 pm

    the function will result in 0 although in the time from 12 am to 4 am there was Val1.
    Regarding TechSupport this is not a bug in the functionality, only…

  5. More functions to support operations on arrays

    The arrays in Expression and Event Frame Generation analyses are useful, but use cases are emerging where more functions are needed to reduce/calculate the arrays in more streamlined fashion. For example, Concat function should support array of characters to construct a string.

  6. Enlarge area for editing analysis expressions

    When editing an Analysis Expression, only 4.5 lines appear. It would helpful if more lines appeared (greater than 20 lines).

  7. Compare timestamps and output most recent value in child elements to parent element

    From a varying number of child elements (all sharing the same template), I want to find the most recent timestamp of a same template-based attribute, and output the value with timestamp to an attribute in the parent element.
    In addition, constantly (event-triggered/periodic) comparing the timestamps of these child element attributes and always output the "newest" value to the parent element attribute.

    Example:

    From 3 child elements, all sharing the same template with attribute "ALARM", I want to have the most recent value comparing the 3 "ALARM"s, and have this timestamp and value in an attribute in the parent element.

    Suggestions…

  8. "Outputs at Start"group

    It would be nice if there were an "Output at start" option to output values at the start of an event frame. Currently there is an "Outputs at close" option for Event Frames.

  9. Enable tracing for one individual Analysis

    On a highly loaded system with thousands of analysis i have one analysis that is misbehaving, missing executions but no skipped count, etc. Currently tracing enables tracing for ALL analysis creating an ocean of logging to plough through for that one event every few days.

    As an AF administrator i would like to turn on Tracing for one or more individual analysis to investigate rare issues that happen over time, without logging ALL analysis evaluations as 99.9999% runs fine.

  11. Ability to clear and not send notifications on Notification service startup.

    We've had issue with Notifications spamming users with events should a PI collective member stop getting data.

    At times, we need to disable the notification service until we can resolve the issue. After the issue is resolved, we need to start the notification service, and need an option to have it not send past email notifications.

    To be clear, clear all past events on service startup.

  13. Extract events from buffer queue files or offline archives

    Currently, the procedure to recover buffer queue files consists of parsing the queue file into a temporary archive and then merging this archive with the registered archive files that overlap with the impacted period.
    This final merge requires to take the registered archive offline, which risks dataloss if new data arrives for the period of this archive. Alternatively, the archive subsystem can be stopped to prevent this dataloss, but this will impact users and calculations that need archive data, which in turn leads to incorrect data or inconsistencies.
    Additionally, in the case of collectives, this needs to be repeated for…

  14. User rights for viewing analytics

    In many cases analytics should not be visible to everyone having right to view an AF-Database. Should be possible to direct whom should have view access to analytics.

    This is an extension to the obivious right to change analytics :)

  15. Trigger Time

    Need a way to utilize the trigger time in analysis functions.

    '*' refers to now or snapshot values

    Using timestamp('triggered attribute','*') only works if there is only one triggered attribute configured.

  16. AF Templates with no data or pi tag not found

    We have an AF structure that uses templates for a few device types. Our templates are setup to resolve PI tags for the device if we have them available. If we don't, it says PI Tag Not Found - which is fine. Once the device is added in the field (out of the office), that AF element will update and work.

    When in PI Vision, the user gets thousands of errors saying the PI tag is not found. I would like an option in PSE to set the element attribute to ignore the error if the tag is not found,…

  17. Possibility to disable the message "An AFEnumerationSet matching the digital state set for PI Point was not found" in PI System Explorer

    I would like to have the option to disable the feature introduced in PI System Explorer 2018 SP2 to pop up the following message when an Enumeration set does not match the name of a digital set in the PI Data Archive:
    "An AFEnumerationSet matching the digital state set for PI Point was not found"

    The message appears every time you open a new element with attributes with not matching Enumeration sets for each of those attributes.This can become very tiresome.

  18. Add Tag Import feature like old "PI Tag Configurator"

    Add Tag Import feature like old "PI Tag Configurator":  PI Builder cannot import attributes of a list of tags pasted into the spreadsheet from another source like "PI Tag Configurator" could.  With PI Builder, if you have want to work on tags that don't group together well by name or description, you have to either make multiple, varied searches or pull in an extra large pack of tags and pair them down.  Also, its tag search is inferior, limited to Name, Source, type, class, units, and description.  There is no way to search by Location1, creation date, etc.  Please review…

  19. Do not re-send alert when Notifications service is restarted.

    When the Notifications service is restarted, any alerts with an event that has not closed will be re-sent.  This is annoying and misleading.

  20. Allow selection of output timestamp for values written by the outputs at close feature in Event Frames

    It would be nice to have the option to select either starttime or endtime of the eventframe as the timestamp for the value that will be written a PI tag using the Outputs at close feature in Event Frames. Currently, it will only write the value with a timestamp of the endtime of the event frame.

    Use case:

    I have an event frame and I would like to see the average of an attribute value for that duration of that time frame on PI Vision. The expectation is to see a horizontal line indicating the average value throughout the duration…
