Note
The reaction to an OFF telegram on the communication object Switch or Switch/status cannot be
parameterized. An OFF command always interrupts the function Slave. The function Slave goes
over to standby mode, in which the brightness values on the communication object Brightness
value of Slave is ignored.
The function Slave is reactivated, if an ON telegram is received on the communication object
Switch or Switch/status or a telegram with the value 1 is received on communication object
Activate function slave.
The master/slave unit is separated, for example, by deactivation of the function Slave (telegram
with the value 0 to communication object Activate function slave). If the function Slave is not
active, the brightness values received from the function Slave via the communication object
Brightness value of slave are not available on its lighting group.
Relative dimming
Options: no reaction
set function in standby
With activated function Slave, the parameter can be used to define the reaction to dimming
telegram to the communication object Relative dimming.

no reaction: A dim telegram is ignored.

set function in standby: A dim telegram ends function Slave, and the DLR/A carries out the
switch telegram. The function Slave is latent and waits until a renewed activation via the
communication object Activate function slave or via an ON telegram to the communication
object Switch.
Brightness value
Options: no reaction
set function in standby
With activated function Slave, the parameter can be used to define the reaction to a brightness
value telegram.

no reaction: A brightness value telegram is ignored.

set function in standby: A brightness telegram ends function Slave and the DLR/A carries out
the brightness telegram via the communication object Brightness value. The function Slave is
latent and waits until a renewed activation via the communication object Activate function slave
