  1. Users wants to include notification/template/target/target template's category in formatted message

    As a user configuring notifications I want to include categories in my formatted message so that I can contextualize the alert based on data already in the system.

  2. Allow EventFrame analysis to link EventFrame to Primary Parent Element

    I want to be able to link an EventFrame to the Primary Parent of the Element the EF analysis is defined on.

    E.g. i use a child element to a Unit to contain the logic to detect and generate downtime events. However, i want the downtime event to link to the Unit, and not to the child element.

    I typically structure AF hierarchies using S95. I also use 'functionblocks' to add repeated functions to e.g. a Unit Element, using AF Element Templates for the functionblock.These also include EF analysis. This leads to the EF linked to the functionblock Element below…

  3. Provide a way to get context information in Expression and Event Frame Generation analyses

    As a user of Asset Analytics I would like to reference parent element attributes, name, and other context information in Expression and Event Frame Generation analyses, even when it is not known during configuration time what the parent element will be so that I can write better conditionals such as : If ParentElement = “Foo” then ‘..\Foo|attributeFoo’ ELSE ‘..\Bar|attributeBar’

  4. Add Process Capability Statistics fundtions (Cpk, Ppk)

    While it is possible to manually calculate Process Capability Statistics, such as Cpk and Ppk, using AF Asset Analytics, it would be much more convenient to have a built in function to calculate these values, specifically in relation to the SQC Western Electric rules analyses available in AF asset analytics already.

  5. Improve Asset Analytics error message: "<Attribute>: Cannot convert <time> to AF time"

    The error message thrown when attempting to use a timestamp input with ValueType other than DateTime in an Asset Analytics calculation refers to "AF Time," which is unclear for many users.

    An example of when the error would be thrown is when creating an expression that uses TagVal('attr1', 'time1'), where 'time1' is a String-valued attribute.

    A better error message would read something like:

    "<Attribute>: Cannot convert <time> to ValueType DateTime"

  6. split analysis is real-time and recalculation part (different logic to be used)

    It would be nice if we could have a "real-time" and "recalculate" part in an analysis. As source data could have changed you probably want sometimes the analysis to act in another way. Example: 2 attributes are used to trigger an event-triggered analysis and assume they write both a value for the same time stamp. in real-time this would mean that the analysis is triggered only once (1 trigger possible per time stamp) and is missing the value of one of the 2 attributes (depends who writes first). but with a recalculation both values are present and because of that…

  7. Permanent disable of non used AF Analysis

    It would be interesting to be able to permanently disable an AF analysis if this one is not used within the template.
    This could be a scheduling option: Permanently Disable
    The status of the analysis would indicate that this analysis is permanently disable and this is "normal".
    There are many cases that this feature will be used to avoid creating multiple templates.

  8. close/open event frames based on events, not transitions

    I use analysis to toggle a boolean or integer from 0 to 1. This is used as source to close/open event frames (step continious mode). this is working fine in real-time. But when I do a recalculation for a part of time in the past (not until *) on the analysis toggling the boolean/integer, the result can be that the last event (on thePI point) in that time frame is equal to the next event. Causing wrong results when the recalculation of the event frame generation analysis is done. If we could tell to close/open an every event we would…

  9. Filtered calculation in PI ProcessBook

    In PI Calcs inside PI ProcessBook or even PI AF, the could be a way of filtering calculations, such as the following


    1. Tag VALUE stores a process value

    2. Tag STATUS stores the asset status

    We want to determine how long VALUE was higher than a threshold, filtering it by the condition 'STATUS'="running"

    Currently, we need to use at least one additional PI Point per conter, but it would be nice if we did not need any and could do it directly from PI PB.

  10. I would like the ability to move searches defined on the PSE management tag from computer to computer

    I have created numerous searches on the management tab of the PSE, but if changing computers or even sharing the searches between workers you currently have to recreate the searches on each computer. Not sure where these are stored currently, but a way to import/export the searches would be helpful.

  11. Set the DEFAULT analysis type to periodic, and/or allow the user to set the default in the config

    The default is set to Natural (event driven), but best practices say that this is a very costly method. Creating thousands of analyses can lead to forgetting to change it to periodic.  My suggestion is that the default should be set to periodic and/or the user should be allowed to set what default analysis type they want in the configuration.

  12. Out of the Box Event Weighed Analytics

    It would be useful to have event-weighed totalizers as out of the box formulas in Analytics for common calculations such as Week-To-day, Month-to-day.

  13. Ability to track source of AF created PI tag to it's origin (dB/element/attribute/analysis)

    I have thousands of tags based on AF analysis, both auto created by AF and some which have been converted from ACE, PE, Totalizers to AF.

    Looking at the tags in Point Builder, DataLink, or SMT I am able to tell by Point Source that the tag is calculated in AF.  But where?  We use a single AF database for our SCADA, AMI, and Generation groups so browsing for an analysis is quite time consuming.

    It would be nice to have a PI Tag attribute that would show the "path" to the analysis.  \Database\Element\Child\Child\Attribute\Analysis and that this information could easily…

  14. Expose triggering input to Analytics

    If an analysis with multiple trigger attributes is triggerred, it is difficult to assess which attribute produced the trigger. Hasvaluechanged has it's limitations, and comparing PrevEvent is also cumbersome.

    Instead of only receiving a timestamp for the Analysis to evaluate, i would like to receive both the Attribute name/path and value that triggered this event.

  15. Trigger an event frame each day on a specific trigger

    I would like to trigger an event frame on a PI Point, however, that trigger may last for several days. During that time I would like the event frame to close at midnight and automatically reopen a new event frame for my event driven event frame.

    Here is an example: Pretend you are measuring the outside air temperature, you want your trigger to trigger when it goes above 50F, chances are your event frame could go on for days before it drops below 50F. Instead of it to go on for days I want a new event frame to create…

  16. "Quick watch" function for analyses

    While creating and/or debugging analyses in PI System Explorer, I would like to have available an instant evaluation dialog.

    This would be something I can bring up empty, and start typing (if in template, use the context of the currently selected Example Element) to evaluate a formula.

    If I right click a formula or expression already placed in a variable I would like to see "Evaluate in Instant Window" or "Evaluate instantly", where the dialog is brought up with that text pre-defined. If the expression you right clicked contains time expressions (such as start time, end time) I would like…

  17. Add thermodynamic properties air tables to Functions list in AF Analytics

    In addition to steam tables, it would be nice to see air tables, particularly for analytics on combined cycle and simple cycle units.

  18. Analysis managament filters for all users and able to export between diferent AFs

    It was so useful for us if we can use filters on Analisis management for all users. We are a 5 people support team, we have the same AF structure in different servers and we must do the same filters user by user, AF by AF.

  20. Increase the discoverability of the windows that are accessible by right-clicking on the Operations pane

    In PI System Explorer → Management, with the Analysis radio button selected, right-clicking in the Operations pane gives the user access to additional windows. Even though this is documented, it is not very discoverable. Users do not expect right-clicking on a dialog-box-like pane to do anything. The windows also serve minor, but still useful, purposes, so the user is unlikely to search the documentation wondering where to find the functionality that these windows offer.

    Please consider eliminating the right-click menu and allowing the windows to be accessed by links, buttons, or icons.
