Hello dear Siemens experts,

I'm currently working on a project including a MTP700 Unified (6AV2128-3GB06-0AX1) with TIA Portal V19 Update 2.

I have a main screen in my HMI where I have a screen window object and several buttons.

I have several screens included in my project. When i click on one button, I execute a global script (I use the screen name as a parameter) where I load one of the screens into the screen window.

What I would like to do in my script is getting the screen properties (screen number, size, etc..) but to no avail (I don't want to read the screen window properties but the properties of the screen I load).

Any suggestions if this is possible and how to do it?

Hi Stefan Arcularius,

Thank you for your reply.

If I understand correctly, I must first load the screen inside the screen window and then I will be able able to access its properties?

It is not possible to access its properties before loading it?

Ah too bad!

Thank you a lot for the answers!

I have another question 

How do I set the reference to the screen I just loaded?

In the example I joined, all I can get are the properties of the Main Screen... I would like to get the properties of Screen 1 or Screen 2 or Screen 3 (depends on the one I load).

Ok, I finally managed to get it to work.

Here is my solution :

Then just need to replace Width with the property I want to get.

However, the same script didn't work yesterday at all. I tried again this morning and it runs perfectly.

There may be some issues with the simulation...
