If the parameter "
Adapt display brightness to ambience
" is set to "
active
", the following settings
are available:
Brightness:
Defines the basic brightness of the display and influences the dimming behaviour of the
display according to the measured value for the ambient brightness.
Minimum brightness
: Defines the brightness that the display has in any case. This brightness can be
set separately for "Day" mode and for "Night" mode.
With activation of the parameter "
Send brightness via object
", object 156 appears.
"
Display - Brightness
" appears. The current value is sent to the bus via this object.
In addition, a "
display switch-off in standby
" can be activated. This can apply either for "Night" or
only for "Day" and "Night". The "
switch-off threshold
" defines the threshold at which the display
switches off completely.
If the parameter "
Adapt display brightness to ambience
" is set to "not active", a fixed brightness is
set for "Day" operation and for "Night" operation.
Here it is possible to control the brightness via object 156 "Display - Brightness", for example to
synchronise several displays.
