• always: The status of the switch state is always actively sent on the
bus via the communication object Status Switch, even when a change
in status has not occurred. Transmission is triggered as soon as the
communication objects Switch, Threshold input or Permanent ON
receive a telegram. Even a scene or preset recall trigger transmission
of the switch state.
On the SA/S x.16.6.1 with the option always, the status is changed if a
telegram is received on the logic objects Logical connection 1 or
Logical connection 2
.
A status repetition is not repeated or resent by a safety change
(forced operation, priority) for all types.
Note
With a change of the parameterization or after a subsequent switching of
the status object, the assignment of the group addresses already
allocated to the Switch communication object is lost and needs to be
reprogrammed.
The status value to be sent is defined with the parameter Object value
switching status (Object "Status Switch")
.
Note
The contact position results from the sequence of priorities and logical
connections; refer for this purpose to
The contact position can only be correctly evaluated should the switching
actions occur via KNX. The SA/S cannot differentiate between manual
switching and a cable break or device fault.
Object value switching status
(Object "Status Switch")
Options: 1=closed,
0=open
0=closed,
1=open
1=closed, 0=open: The value 1 is written with a closed contact, and the
value 0 is written with an open contact in the communication object
Status Switch
.
0=closed, 1=open: The value 0 is written with a closed contact, and the
value 1 is written with an open contact in the communication object
Status Switch
.

The output can adopt a defined state on bus voltage failure with this
parameter.
