4.2.2 Activating screen darkening
If a screen with high contrast is displayed unchanged for longer than an hour, the
screen must be switched dark (screensaver) in order to protect the TFT display
against so-called "freezing" of the last displayed screen.
Activate using PLC
You can activate the screen darkening with the PLC in DB19.DBB0. The PLC has
priority over the entry in the display machine data.

Activate using the machine data
Via the display machine data MD 9006: DISPLAY_BLACK_TIME is used to specify
the duration (max. 60 minutes), after which the screen is automatically darkened if
no key is pressed on the keyboard.
In this display machine data, the "Screen dark from HMI Embedded" function can
be started with the following entry:
MD 9006 = 1 < time in minutes, e.g., 1 >
MD 9006 = 60 < time in minutes, e.g., 60 >
MD 9006 = 0 Deactivation of the function (default setting)
