Communication objects Slave function

If the additional function Slave has been selected in the
following communication objects appear.
The status value of the Slave function is fed back. In the
parameterize whether the status of the Slave should be sent. In this case, the status is sent via the
communication object Fct Activate Slave/Status.
No.

This communication object is enabled if, in the
enabled.
This communication object is used for activation/deactivation of the Slave function.
During deactivation, the lighting group behaves like a "normal" lighting group of the DLR/S. The Slave function can be
reactivated when the DLR/S receives a telegram with the value 1 for the lighting group via this communication object.
By setting the T flag, the communication object is actively sent after KNX bus voltage recovery.
Telegram value:
As long as the Slave function is activated, the lighting group can be controlled in two ways:


In the
telegram interrupts the Slave function.

This communication object is enabled if, in the
enabled and, simultaneously in the
Slave is programmed with the Yes: via object "Activate Slave/Status" option.
In this case, the status of the Slave function is sent on the KNX, in addition to the functions described above.

0 = Slave not active
1 = Activate Slave
Externally by the KNX via the communication object Brightness value of slave
Internally directly from one of the controller groups 1...8 (master). The brightness value of the master is transferred
directly in the DLR/S to the slave. As a result, the KNX bus load is minimized. Optionally, the brightness value from the
master can be provided with an offset, whereby the second lamp strip (Slave) is controlled with an increased or reduced
brightness value in comparison to the master.
Parameter window - Gx Slave, page 112, you can parameterize whether a switch, brightness value or relative dimming
Note
With the Slave function selected, the DLR/S can only display the switch status via the common
communication object Switch/Status (no. 30) on the KNX. There is no separate communication object for
the switch status.
