Communication objects function - Slave

If the additional function Slave has been selected in
communication objects appear.
The status value of the function Slave is fed back. It is possible to parameterize in
Gx Slave, page 108, whether the status of the function Slave should be sent. In this case, the status is
sent via communication object Activate fct slave/status.
No.

This communication object is enabled if in
This communication object is used for activation/deactivation of the function Slave.
During deactivation the lighting group behaves like a "normal" lighting group of the DLR/A. The function Slave can be
reactivated when the DLR/A 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 function Slave is activated, the lighting group can be controlled in two ways:


In Parameter window - Gx
telegram interrupts the function Slave.

This communication object is enabled if in
and simultaneously in
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.
Function
Activate function slave
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 control groups 1...8 (master). The brightness value of the master is transferred directly
in the DLR/A to the slave. As a result, the KNX bus load is reduced. Optionally, the brightness value from the master can
be provided with an offset, whereby the second lighting strip (Slave) is controlled with an increased or reduced
brightness value in comparison to the master.
Slave, page 108, you can parameterize whether a switch, brightness value or relative dimming
Note
With selected function Slave, the DLR/A of the switch status 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.
