Planning and application
The reaction to the switch on telegram with the value 1 to the object Switch
can be parameterised. If the slave operation is activated, the Dim actuator
output strictly adheres to the brightness value, which is predefined by the
object Brightness value of slave. Brightness values on the object Brightness
value are ignored. A telegram with the value 0 on the object Activate slave
mode deactivates slave mode. A telegram with the value 1 switches on slave
mode again. This activation or deactivation is also displayed in the first bit of
the status byte.
A switch off telegram with the value 0 on the object Switch has the effect that
the slave mode is deactivated. In this case, the slave mode is in a standby
state and waits in the background for renewed activation. A renewed
activation can be implemented by a telegram with the value 1 to the object
Switch or via the object Activate slave mode. As in standby mode, the slave
mode continues to be active in the background and is waiting for activation,
the first bit in the status byte will always indicate the activated slave mode
with the value 1.
The same behaviour results when in parameter window
parameterise that a dim, switch, value command, preset or scene recall
deactivates slave operation. Slave mode is in standby and can be
reactivated via a telegram with the value 1 sent to the object Switch or
via the object Activate slave mode.
The parameterisation no reaction has the effect that no dim, switch and
value command can be executed. Also a preset or scene recall and storing
of a scene has no effect.
The slave mode remains activated. However, using the object Set preset
a new brightness value for a preset can be saved.
The parameterised value limits in the parameter window
for the slave mode. The undershoot and overshoot of these limits are set
using the parameterised minimum or maximum brightness value.
If the master sends the brightness value 0 the lighting is switched off.
The behaviour of the slave mode after bus voltage recovery can be
parameterised.
