Hi lucasribas,

take a look at the "DataSet" object. I have seen this in sample projects from Siemens.

Kind regards
Stefan

Using a dataset object for section-global data I could build the screens the way I needed it.

I used something like

HMIRuntime.UI.DataSet.Add('TagName', 'TagValue');

 to create and load a value in the tag, and then something like

let data = HMIRuntime.UI.DataSet.Item('TagName');

 to load the value in a script inside another screen's object.

After I processed the 'TagName' where I nedded it, I used the following command to clear all the dataset stored tags: 

HMIRuntime.UI.DataSet.Add('TagName', 'TagValue');

 This way I can declare again the tag 'TagName' in another structure, what I used a lot here.

Thank you very much for your help Stefan Arcularius!!
