The last brightness value is the last constant brightness value. This can
result from the setting of a brightness value using a switch or dim command
and through a scene, preset or staircase lighting function.
Note
At bus voltage recovery the last brightness value is lost.
Until a new last value is recognised, the output of the Light Controller
switches on with the maximum brightness value, whereby the dimming
value is taken into consideration.
If the slave mode is in standby mode and the Light Controller receives
a telegram with the value 1 on the object Switch or Switch/Status,
the last brightness value is not set. The slave mode is activated directly
and the brightness value from the object Slave brightness value is set.
If switch on with the last brightness value is parameterised and the output
is switched on, the brightness value remains unchanged if a new ON
command is received. This is because the current brightness value
is seen as the last constant brightness value by the Light Controller.
Time for passing from 0...100 % while
switching in s [0...65,535]]
while switching off
(0 = immediately)
Options: 0...65,535
while switching on
(0 = immediately)
Options: 0...65,535
This parameter defines how fast the lighting switches on or off with
a switching command. The set dimming time relates to the full dimming
range of 0 % to 100 %.
Note
The reaction of the Light Controller with activated light control is
parameterised in the parameter and
