Status response of brightness value
Options: no
yes: via object "Brightness value/Status"
yes: via separate obj. "Status brightness value"
The parameter defines how the current status of the brightness value of an
output (lighting) is sent on the bus.
•
no: The brightness value is not actively sent on the bus.
•
yes: via object "Brightness value/Status" The brightness value is sent
on the bus via the object Brightness value/Status.
•
yes: via separate object "Status brightness value" An additional
Status brightness value object for the feedback is enabled.
Note
The changed, updated brightness value is sent only at the end of the
dimming process, i.e. when the end value is reached after switching,
scene or preset recall. This can mean that during the dimming process
the current brightness value is not displayed.
With a change of the parameterisation or after a subsequent switching of
the status object, the assignment of the groups addresses already
allocated to the Brightness value object are lost and need to be
reprogrammed.
With the options yes:... two further parameters appear:
Send
Options: only after changing
if value change and triggered by brightness com.
•
only after changing: The brightness status is only sent when
a change occurs.
•
if value change and triggered by brightness com. With every value
change and via the object Brightness value the brightness status
is sent even when the brightness does not change.
Telegrams to the switch or dim objects, scenes or preset recalls
as well as the activation of the staircase lighting function does not
initiate sending of the brightness status, if the brightness does not
change as a result.
Disable time after sending object
"Status brightness value" in s [0..10]
or
Disable time after sending object
"Brightness value" in s [0..10]
Options: 0...10
With this parameter sending of the Status brightness value can be
limited. As a result the bus load can be reduced significantly.
This defines the time intervals at which the brightness values are
sent on the bus. The disable time only relates to the status objects
Status Brightness value and Brightness value.
