Hi,

In WinCC professional you can create a PDL and customize it as a kind of a template. Then you go to the right of the screen and select Library. The Library navigation should open and you can drag and drop the "template" PDL to master copies. 

Now you have a template which you can drag and drop back to the left navigation of your project to create a new PDL.

You have not the same option in WinCC V7.4 but you could do it similar:

You create a template PDL which is intended to be used as template PDL. 

This one can be marked as favorite PDL (right button marked as favorite).

Then in case you need to "duplicate" or reuse the template you can go to the project path in Windows and open "GraCS" folder which contains all PDLs. 

Now you select the "template" picture and copy paste it on the same folder with a new PDL name. 

These steps are also creating a template which is not as smart as in TIA Portal but it works at least.

B.R. 

Yes, but when I change something on that (lets call it Template) picture, other screens do not recognize that change, and become blank. I need something as real template.
