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

brightness value" 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 function Slave 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.

telegram interrupts the function Slave.
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:
In the case of internal master/slave communication, the brightness value is transferred internally in the DLR/A from a
controller lighting group. With parameter Slave is controlled via in
parameterize from which control 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 lighting 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: Slave, page 186
Via the communication object Master: Offset activate (No. 40) the offset can be switched on or off.
