Communication objects Group x

It is possible to parameterize status messages. The communication objects change.
Depending on the parameterization, the communications objects change, e.g. for group 1:
Separate communication objects no. 40 and 41 or common communication object no. 40.
Separate communication objects no. 43 and 44 or common communication object no. 43.
No.

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
are 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 correspond-
ing brightness values.
If one of the additional functions Sequence or Staircase lighting are 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 the object
Switch/status. Generally, the status messages use a separate communication object Status switch for this purpose. In

The communication object is enabled if in
Switching state of the lighting group has been parameterized with yes: via object "Switch/status".
This communication object has the same functions and properties as the communication object Switch. The status is addition-
ally fed back. Additionally, the value of the communication object is also updated if this is not sent on the KNX.
Telegram value:
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.

This communication object is enabled if in
Switching state of the lighting group has been parameterized with yes: via separate object "Status switch".
Telegram value:
The value of the communication object directly shows the current switch state of the lighting group. The status can be sent
after a change and/or after request.
