This communication object is enabled if, in the
the parameter Select additional function.
Using this communication object, the offset for the master/slave control is activated or deactivated. In this way, for example,
the offset is switched off (deactivated) or switched on (activated) at a determined level of external brightness or by a timer.
With deactivated offset, the slave is controlled with same brightness as the master.
When an offset is activated, the brightness value of the master has the parameterized percentage applied and is made
available to the slave via the communication object Master: Brightness offset.

Using this communication object, the internally set variables (control parameters) in the DALI Light Controller can be read or
defined for the current setpoint.
Thus, different setpoint settings for light control can be set for various applications, e.g. for competition and training settings
in sports centers. The procedure is described under
It is inadvisable to transfer the control parameter setting for a setpoint from other rooms, as it is practically impossible that
both rooms have exactly the same reflection properties and brightness conditions. Furthermore, the characteristic which
controls the lighting is determined during the automatic artificial light calibration. If a control parameter for a setpoint value is
still to be transferred regardless of these facts, it must be assumed that the light control will be inexact (large setpoint
deviations).

Note
This communication object can be read and written in the ETS.
However, the value of the communication object is not sent automatically on the KNX by the DALI Light
Controller, regardless of whether the T flag is or is not set.
