    Would you only have True/False as your possible states?

    Since the first release of Asset Framework v2.x in December of 2007, it has always supported only Microsoft SQL Server as the database backend. As such we have a very large investment both in software code and testing infrastructure to support this configuration. We have recently received some customer requests for Asset Framework to additionally support AWS RDS as the database backend, as evident by this User Voice idea. We have not tested Asset Framework with AWS RDS as the database backend and thus it is currently not a supported configuration. The product management team at OSIsoft continually evaluate customer requests and feedbacks. This idea will be assessed and prioritized along with all the other ideas for Asset Framework and if we decide to start work on this idea, we will adjust the User Voice status accordingly. Please continue to vote and provide detailed use cases to help us prioritize our backlog.

    This is an example of ad hoc calculations for PI Vision displays. As such, I'm moving this idea to the PI Vision section.

    Our current development cycle does not include this request. We will update this idea if the status changes.

    There are complexities associated with this idea in that we would need to know the content of the archives both from the source and also destination. Did I understand your request correctly?

    PI System Explorer (PSE) is just an AF SDK client. Fundamentally it's no different than any other AF SDK client such as PI Vision. As such, PSE uses the AF SDK to interact with data stored in the AF Server (SQL Server) and Data Archive. When you retrieve data in PSE, the AF SDK tries to retrieve the data and in the case of a missing PI Point, PSE (as a client) interprets that and shows "PI Point not found". Similarly, PI Vision is doing the same thing as an AF SDK client. In order to achieve what you're describing, the best way to accomplish that is probably to implement an option in PI Vision to ignore these errors. As such, I'm moving this idea over to the PI Vision area.

    In PI System Explorer, which itself is an AF SDK client, it is in fact true that you're changing the Display UOM of the relevant attribute within the PI System Explorer graphical user interface. One must take note that this is a client side setting.

    User often forgets that PI System Explorer is just an AF SDK client and nothing more. It is not possible to change the Display UOM in PI System Explorer and then persist that same Display UOM automatically in another AF SDK client unless one changes what is stored in the database. When you change the Display UOM in PI System Explorer, that change is only valid within the context of that particular AF SDK client.

    If your desired end goal is to change the shown UOM in PI Vision, which itself is an AF SDK client, please vote for the relevant idea under the PI Vision feedback section.

    Thanks Asle, we'll look into this.

    Hi, can you provide some example use cases? What type of events are you trying to capture with event frames?

    Hi,
    While we continue to evaluate the relative priority of this request, have you considered using PI Builder to help with your configuration needs?

    Please help me understand why you wouldn't just remove this analysis if it's permanently disabled in the template?

    Can you help me understand what you mean by "set a period of time after the analysis...."? Are you asking to trigger an analysis after a certain amount of time even though there were no event-triggers?

    This would be a fairly substantial and impactful change. During import the XML files are parsed line by line, thus the exported XML from the source has some builtin ordering to facilitate the import process. This is so that, for example, we would know if referenced objects exist during the import process.

    Your requests for tooling to facilitating Dev->Test->Prod is noted and we will internal continue to evaluate what we can do and relative priorities with other requests.

    Matthew, in the analysis Management plug-in, the element search is by name, with support for wildcards. This search includes child elements. I just tested this and seems to work as expected.

    AdminStephen Kwan (Product Manager, OSIsoft) commented  · 

    Which version of AF are you using? In recent versions, we allow you to search by individual analysis templates in the management plugin and we also allow you to perform element searches that includes Descendants.

    A "subscriber" is known to PI Notifications Service as basically just an email address. In order to provide a local timestamp, there needs to be a way to correlate a timezone with a subscriber. I'm unsure as to how to do that given that in a majority of use cases, someone configures the notification to send to a "subscriber" so it's really not a self service use case. Thoughts?

    AF is a multi user system. Would you want such a list for every user that configures Notification?

    Unfortunately this is quite difficult to do. The Data Archive doesn't keep track of the exact application that is writing to a PI Point. As such, you can create two applications that write to the same PI Point currently. To complicate matter, the same service (PI Analysis Service) is writing to all the output PI Points from all the analyses so the Data Archive certainly cannot differentiate one from the other. Any prevention of these configuration errors would need to be done elsewhere.

    In response to Mario Huys, "User is trying to link a csv-file as a t..."
    It really doesn't make a lot of sense to link a table from the client.  In this case, after the user configured a linked table to an attribute and then another user tries to access this attribute, the other user would have no way to get to the table.  The AF Server must know how to get to the linked CSV file to serve multiple users.
     
    Maybe I'm misunderstanding what he's trying to do?

    Please describe your use case. What problem are you trying to solve?

    Sorry Mike, I didn't make the connection from seeing just the name of the poster on PI Square.  Now I know.

    PI System Explorer is a configuration tool for configuring objects in AF.  Are you using PI System Explorer as a visualization tool?

    As to hyperlinks, you can configure the extended property of an element with a hyperlink.  You can also configure an attribute of an element with a hyperlink.

    Having said that, I'm curious as to what kind of hyperlink you would put on an element?  Where would the hyperlink take you?

    In response to Sean Jost, "So we used AF SDK to export an attribute..."
    Sean, are you able to provide additional information on what your use case(s) are with concrete examples?  I am guessing here a bit, but do you have assets like a pump, that you want to added to the AF hierarchy and you want to use ID from a foreign system as a unique way to track this asset through it's lifetime?
     
    While we're on this, David previously mentioned the fact that elements can have extended property which can hold key-value pairs that you can search on.  Perhaps that does what you need?

    AdminStephen Kwan (Product Manager, OSIsoft) commented  · 

    Although your question was around the AF SDK, have you considered using the XML import/export option to preserve unique ID's?
