  1. 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:

  2. 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…

  3. 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).

  4. 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.

  5. 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…

  6. 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.

  7. "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.

  8. 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.

  9. Provide the capability to apply compression on uncompressed data, aka recompress using offline archive utility.  See work item 6944OSI8.

  10. 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.

  11. 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.

  12. 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.

  13. 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.

  14. 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…

  15. 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…

  16. Multiple instances for Asset Analytics

    As a PI administrator I would like to be able to create multiple instances of "PI Analysis Service" windows service for these reasons:
    - avoid new potentially problematic analysis from affecting the ones that are operational and working correctly by setting one production instance and one test instance for example.
    - every instance could have its own log files and we could move some analyses to a new instance to troubleshoot them
    - make possible to distribute the resources usage for asset analytics on more than one server

  17. Optimize SID resolution when viewing mappings in PI System Explorer

    In PI System Explorer → File → Server Properties, the Mappings tab loads much more slowly than the other tabs when you have a slow connection to the PI servers and the domain controller.

    In tech support case 00589952, I found that the loading time of the Mappings tab was roughly the same as the total time from running the "net user /domain" command for each mapping. This 1-by-1 approach is not efficient. Note that in my case, I had a mix of local accounts on the PI AF server and AD accounts.

    Please consider some of the following optimizations: …

  18. Future Data recalculation and analysis-triggering

    1. Allow auto recalculation of future data. This makes sense to consider, because forecast revisions are a general, industry-agnostic thing.
    2. Another related request might be to add a new option of analysis triggering. Right now for event-trigger analyses, it triggers based off current value. It would make working with future data easier if there could also be an event-trigger for when the latest (most future) value arrives.

  19. PI EFGen interface : allow configuration of events without OS-admin rights

    PI EFgen interface is built in such a way that it is not possible to configure events without Windows-Admin rights on the machine hosting the interface. This is not relevant in term of security and we would like to let key-users configure events with only PI-admin rights.

    This request is similar to what is available in PI Batchgen interface, where you can configure batches with PI SMT and you don't need any OS-admin rights.
