Continuing in the Unified madness.

How is it possible to project a simple, basic, elementar and always essential "goback" page button ?

Please do not tell that the unique solution is ... " to make a java script", I won' t believe.

Madness, madness!

You have to save the previous screen's name or number somehow, and call this up when pressing back.  You don't strictly need to do it with scripting, but if you don't, I think you might be restricted to the last visited screen.

Storage of the previous screen(s) depends on whether you want 1 level of back or multiple.  I did multiple with a single string by separating the previous screens with slashes, like: "Home/Settings/Timers1/Timers2".  PM me if you'd like details of this (it uses scripts).  Other multi-level back functions use arrays (there are Siemens-published examples of this).

In case you use the Siemens Templates (Template Suite) as a base it's rather easy to do.

Also without scripting

Go to the ScreenWindow "swContent" in which all Main Screens are shown

All Tags Below must be  LOCAL! Session Local! WSTRING! Tags:

Required Tags: "SCREEN", "ACTUAL_SCREEN", "LAST_SCREEN"

Go to Properties -> Screen (add a Tag "SCREEN")

Go to Properties -> Screen -> Change (and copy the a "ACTUAL_SCREEN" Screen Tag to "LAST_SCREEN" and below the "SCREEN" to "ACTUAL_SCREEN")

Then you can anytime use the Tag "LAST_SCREEN" to call the last screen

Hello Davinator,

The WinCC Unified Toolbox contains an example of screen history with a back button. I've implemented the scripts in our corporate library and it works at several clients with no problems.

I used JavaScript.  This video helped implement it on a recent HMI
