    PI DataLink 2013 missing feature?

    Asle Frantzen

      Is OSIsoft discouraging the use of AF Models?

       

      The reason I ask is that I can't see my models when browsing my AF database through the PI DataLink 2013 search dialog. Only elements are visible in the browse section on the lower left side of the screen.

       

       

       

      Normally I stick to elements when creating hierarchies, but this time I had a T&D project where I wanted to try out the connectivity functionality included with the use of AF Model. Well into the project I discover that users can't browse this hierarchy (they do get search results from it, but they can't browse). I then proceed to contact techsupport, where I'm presented with the following answer - and a request to "join vCampus" to push enhancement requests...

      ...Unfortunately, our product development team decided to not include such feature in the current version of DataLink because they think the way it is now is what most of our customers are looking for...

       

      It would be intersting to hear why this is not available (why it's not a bug). Especially since searching a model is possible - and once you know the Excel formula you can easily replace the path to the attribute with one of your own.

          Asle,

           

          What are you trying to accomplish with the models and PI DataLink?

           

          The models, ports, cases, and analyses functionality was only used by Sigmafine.

           

          Thanks,

              Well, with the upcoming release of the PI connector for ESRI ArcGIS I would like to take advantage of the connectivity functionality with ports, so that I can build a graphical model of the transmission network from the connected elements inside the AF Model. Substations, transmission lines, bus bays, etc. are being connected to each other during setup, and once we start thinking about putting the data on a map some time in the future, my goal is that it's just a matter of collecting the data which is already connected.

               

              I understand this is old stuff, and I also know that AF Cases and AF Analyses only are accessible by code. But the models and ports are still there, and for most demo's from OSIsoft regarding AF hierarchies, there's at least one AF Model visible. To me that's an indication that it's still being used (maybe just for Sigmafine users, but still).

               

              Are you saying this is deprecated and that I need to build the connectivity model outside the PI System?

                  Asle:

                   

                  In the current AF product, we do not plan on removing these capabilities as it's required for SigmaFine.  Improvements to connectivity models are not our current focus of product enhancements, but rather it is something that is in our longer term backlog. In order to best support such a feature, we need to go beyond just support in AF, we have to consider interfaces/Connectors and also client tools.

                      Asle,

                       

                      I'll connect you with our Esri PM. She might be able to offer you some suggestions on ways to visualize network models specific for Esri.

                          SynerGEE has network visualization screens – where it’s all about connectivity - gas, water, electric network models.   More details here:http://www.dnvgl.com/software/default.aspx#Software-solutions

                              Matt: Thanks, always good to get "outside" opinions on our plans. We're also in contact with ESRI Finland, who delivered ArcGIS to our client, and we're going to meet with out client in Helsinki in 2-3 weeks.

                               

                              Steve: I understand your situation, but I still feel you shouldn't leave out AF Models from browsing/searching in client tools. The answer I got from techsupport (...consulting out DataLink specialist and development team...) was: "None of our products (like CoreSight, ProcessBook, DataLink …) allow for the searching of AF model elements".

                               

                              This isn't exactly true for ProcessBook (which allows browsing for attributes, and elements of interest) and DataLink (allows searching but now browsing). I'm not requesting any new functionality to the AF Models, I'd just be interested in utilizing the features already available - without losing other vital functionality.

                               

                               

                               

                              Anyways, I see there is a possible solution here. Under my AF Model I only have two elements today (Primary substations, secondary substations). If I change my model to a normal element, and then create a new empty model instead - I can make references to those two elements in the newly created model. By doing that I should be able to always have an updated "copy" of my hierarchy below the model, and the only change would be that I'd have to maintain the connectivity in the model instead of the main hierarchy.

                                SynerGEE has network visualization screens...

                                 

                                Thanks for the tip. I think all our T&D clients have similar tools, but what we're interested in is solutions for web - over ArcGIS or Google maps, where we can show health information together with basic connectivity information.

                                  Gopal - do you know what capability SynerGEE Gas has to integrate with the PI System. I am aware that the data modeller can import network models exported from GIS, what I want to do is export the network model from SynerGEE Gas and use it to build/maintain the PI AF model.

                                   

                                  I have asked DNV-GL but not heard back from them yet.
