Yes this is possible. We can configure a display like this using Collections and the Asset Search filtering released in Vision 2017. By adjusting our Asset Search criteria, we can decide which child element data appears in our display based on a root parent element. I would recommend you watch the following videos to get more information:
In the second video we create a dashboard showing Philadelphia and Springfield side by side, but this could also be done with the Asset Swap feature (the upper bar you mention) swapping between sites.
Let me know if you have further questions!
Thanks for your answer. I´ll try that out!
Do you know if it´s possible to configure Vision not to Display attributes if they are not specified or in case of failed calculations?
I am trying to define some templates on AF for Equipment that sometimes may have an Attribute and sometimes not. I want to use the same Vision Display for both, so in case one Attribute is not specified (i.e., has no value or is not connected to a PI Point) this is simply not shown. By way of example, consider a Equipment type in which the inflow sometimes is measured in kg/h and sometimes in m3/h. I would like to have both attributes (mass flow and volumentric flow) on the General Display, but only Show the one which is specified. Thus I can Change between Equipment (drop down bar) and see how my Display automatically updates the relevant Parameters.
Reading a bit I saw that for failed calculations there is a command NoOutput(), but as I don´t want to store my calculations as PI Points I did not further explore this Option.
Thanks in advance.
This might be a bit tricky, but it might be possible! I'm not sure I haven't tried it. My guess is you could try the following:
1. Configure an AF analysis that does some logic that outputs a single point (kg/h or m3/h) and then the Vision display will pull that. This is what you've already mentioned, and yes using our recommendation this would consume PI Points.
2. In the next release, you might be able to configure something where only a certain attribute appears given a specified set of conditions. This is an enhancement request seen here: Graphics: Make visible/invisible based on tag value – Customer Feedback for OSIsoft & the PI System
3. You could probably create a custom symbol that does this. I personally haven't explored much with the extensibility in PI Vision, but we have a whole course built for it if you're curious. I would recommend checking it out! Customizing PI Vision with Extensibility
Let me know if that helps.
