depending on the settings in the project.

You can find details on configuring the PROFINET device names in the WinCC 
information system.

●  When the touch screen is briefly touched or a key is pressed, the screen brightness is set 
to full brightness. 
●  If you press the touch screen or the "Cursor up" key for a long time, the screen brightness 
increases incrementally.
