This communication object is always enabled in order to enable setting of a brightness value without further parameter
setting. When the Slave function is activated, the brightness values received via this communication object are normally
ignored.
Optionally, however, if a telegram is received on this communication object, the Slave function can be deactivated. The
appropriate parameterization must be carried out in the

This communication object is enabled if, in the
, page 67, the additional function Slave is
enabled and, in the
, page 112, for the Slave is controlled via parameter, the Object
"brightness value of slave" option has been selected.
Via this communication object, the slave lighting group receives the brightness value, e.g. from a higher level light controller
group.
If the Slave function is not active or is latent (standby) after an OFF telegram with the value 0 to the communication object
Switch or Switch/Status, the telegrams to the communication object Brightness value of slave have no effect.
In the
, page 112, you can parameterize whether a switch, brightness value or relative dimming
telegram interrupts the Slave function.
Brightness values, which are above or below the predefined max. or min. dimming values (dimming thresholds), are not set.
In this case, the dimming limits are set.
Telegram value:
0 = OFF, the output is switched, off, the Slave function remains active.

255 = 100 %
In the case of internal master/slave communication, the brightness value is transferred internally in the DLR/S from a
controller lighting group. With the Slave is controlled via parameter in the
possible to parameterize by which controller the brightness value is received.
Regardless of whether the master brightness value is externally or internally received, the master brightness value can be
increased or reduced by an offset. In this way, a second lamp strip (slave) can be controlled with another brightness value
other than the master brightness value. Thus, the maximum level of energy conservation can be achieved.
For further information see:
The offset can be switched on or off via the communication object Master: Offset activate (no. 40).
