How to Pass Strings from a Graphic Element to an Object Display using the Aspect View Invoker?

Hello,

I have a graphic element, which has a string input property "ip::D1String" with value "Auto". I've added an Aspect View Invoker to the element, and pointed it at an Object Display for the object type. This part works, and when I click on the graphic element on a page, it opens the Object Display in a popup window, and displays the correct name/description for the selected object.

Now I want to try to pass the string to the Object Display to be displayed in a text label.

On the Aspect View Invoker, I have set the "NumberOfNamedValues" property to 1, which created a new property on the Aspect View Invoker called "NamedValue1". This property has been set to "NamedValue("D1String", ip::D1String)".

Now I need to retrieve this parameter in the Object display that opens... however, creating an Input property called "D1String" on the Object Display does not load the value of ip::D1String from the graphic element (or at least, doesn't display it in the text label).

Does anyone know how to read the NamedValue in the newly opened graphic, so it can be used on that page?

Regards,

Energiser

See the attached files for how to define a General Property with read/write permission. You could change the value from you graphic at runtime if needed, see the input field. You can use the value in your graphic in a simple text field or in the same way at your input property of your graphic element.

The main point is that the value is hosted at the object and not within the graphic!

If I understand you right you try to transfer a input value from a graphic element to the object display. I don't think that it is possible this way. You need to host your value with the object. Try a "General Property" aspect at your object. You should be able to access a value in General Properties from your Object Display as well as from a graphics element.

Thanks for the suggestion Erik.
So the object display can now read this General Property that I have added, but my question is how I can write my string value to that property, from the Input Property of my Graphic Element?
Unfortunately I haven't been able to find any info on General Properties in the help documentation, so I'm hoping you'll be able to point me in the right direction.

I don't understand why you want to have that string as an input value at your graphics element. Is that a static text or do you mind to edit it on runtime? The main thing in 800xA is the object, with graphic aspects like the object display. Why not display the sting in your graphic in the same way as in the object display (that just another graphic is).

To give a bit of context, the object is an MB300 Genusd1, and in this particular case it's being used as a mode selector. In all existing mode selector cases, it's selecting between enumerated values Auto (0), Manual (1), Out of Service (2), but all the elements are set up generically, so the graphic element could be displaying anything at all. I'm trying to set up the Object Display such that it has the selector buttons on it, and I want the text on the selections to be the same as the display on the graphic element... so it has to be generic, with the string values being defined as input values on the element.
Ideally, I'd put the selector functionality on the Faceplate, but since it's a genusd, and whoever set up the system years ago also uses genusd1 for other types of object, I can't put the selectors on the faceplate, as then they'd appear there for objects for which the buttons aren't appropriate.

Thanks for all your assistance Erik.
While experimenting with the General Properties as you suggested, I created a copy of the default Faceplate and pointed my Aspect View Invoker at the copy... and it worked. An ABB rep had previously given me the impression that it was impossible to have multiple faceplates for a single object type. I have now transferred my controls over to this custom faceplate.
Since I was unable to successfully write to any General Properties, I have decided to hard-code the labels for the time being. For now, I'm guessing that I was unable to write the properties due to either a permissions issue, or the fact that this 800xA system is not currently connected to a controller (wouldn't have expected it to matter for General Properties, but wouldn't be surprised if it works once I get to test against a controller).
Thanks again.

If you have an Input Property instead of an input Field, you can use the Element "Property Transfer" in PG2 to write the Input Property into the General-Property-Aspect.

I know whats your problem. Your "General Property"-Aspect is inherited.
Go to your Object in the object structure. There you have an Aspect called "XXXX Type Definition". Go to Tap "Aspect Control". Unselect "Inherit to all instances" and Select "Copy to all Aspects"
In this way each instance of your object has its one general property and is no more inherited.
