This communication object is enabled if in
This communication object is used for activation/deactivation of the function Slave. With deactivation, the lighting group
behaves like a "normal" lighting group of the group-orientated DGN/S without function Slave. The function Slave can be
reactivated, if a telegram with the value 1 is received on the DGN/S via this object.
By setting the T flag, the communication object is actively sent after KNX voltage recovery.
Telegram value:
As long as function Slave is activated, the lighting group is controlled using the brightness value received via communication
object Brightness value of slave.
In the Parameter window - Gx Slave
telegram interrupts the function Slave.
Note
With selected function Slave, the DGN/S can only display the switch status via the common communication object
Switch/status (no. 40, 48..., 160) on the KNX. There is no separate communication object for the switch status.

group is programmed with the option yes: via object "Activate slave/status".
In this case, the status of the function Slave is sent on the KNX in addition to the functions described above.

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

This communication object is enabled if in
The slave output receives the brightness value via this communication object, e.g. from a higher level light controller, which is
parameterized as the master.
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.
In the Parameter window - Gx Slave
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:
