Communication objects Group x

It is possible to parameterize status messages. The communication objects change accordingly.
Depending on the parameterization, the communications objects change, e.g. for group 1:
No. 30 and 31 separate communication objects or common communication object No. 30
No. 32 and 33 separate communication objects or common communication object No. 32
No.
30
Using this communication object, the lighting group is switched on or off with the predefined brightness value
window Gx
Telegram value:
When an ON telegram is received, the parameter settings define if a predefined brightness value or the value before switch
off is set.
If the parameterized lighting group is switched on with any brightness value and it receives a renewed ON telegram, the
parameterized brightness switch on value is set. Any ongoing function Burn-in currently active has a higher priority, so that
under certain circumstances individual devices can only assume a brightness of 100 % or OFF.
Other parameter settings define whether the brightness value when turned on is dimmed to, or whether it takes immediate
effect. Switch on values, which are above or below the maximum/minimum brightness values, are replaced by the
corresponding brightness values.
If one of the additional functions Slave or Staircase lighting is activated, this function is triggered with an ON telegram
(value 1) and the respective timing is started. An inversion is not intended.
It is possible to parameterize that the switch status is fed back via the communication object Status switch or via
Switch/status. Generally, the status messages use a separate communication object Status switch for this purpose. This
can be parameterized in
30
The communication object is enabled if in
switching state is set with yes: via object "Switch/status".
This communication object has the same functions and properties as the communication object Switch. The status is
additionally fed back. Additionally, the value of the communication object is also updated if this is not sent on the KNX.

0 = OFF or OFF and status: Lighting group switched off
1 = ON or ON and status: Lighting group switched on
Note
If several KNX group addresses are assigned to the communication object Switch/status, the status
address should be set as the sending address. In a KNX group with several status messages, it is useful to
allow just a single group member to feedback the status.
