    PI Vision - Element Parent Changed

    TimCarmichael

      In managing multiple sites, there is at times a desire to establish a consistent 'look and feel' to the element hierarchy.

      If an element is moved within the hierarchy to have a new parent, what happens to the PI Vision displays that referenced attributes in the element?

      Is the relationship maintained or does it break?

      If it is NOT maintained, as I suspect, how can the displays to updated to reflect the revised path to the attributes?

      Are there tools available to update the displays or is it is a 'hunt and peck' approach?

          Hi Tim,

           

          You are correct.  If you move an element to a new parent, the displays will show "Attribute Not Found" errors.  This is because technically, the element is no longer the same and is considered a brand new element. 

           

          If this element occurs on 1 display, you will need to recreate the objects with the data item path pointed to the new element path.

           

          If this element is found in a lot of displays, I'd recommend that you contact OSIsoft Tech Support.  We have internal scripts that will assist you on correcting your displays.

            Welcome to the world of using strings to define paths...

             

            I do most of my work on a development system and frequently have to rearrange things to try out new ideas or because I an analysis only works with a different style hierarchy... I use the asset context fields to let PI Vision find information for me whenever possible so I can restructure the AF hierarchy without breaking everything...

             

            I recently changed the name of a template with the expectation I would have to modify the template name in my asset selection fields in PI Vision... Imagine my surprise when I checked the PI Vision display and the template names were already changed
