Status response of switching state
Options: no
yes: via object "Switch/Status"
yes: via separate object "Status switch"
•
no: The switch state is not actively sent on the bus.
•
yes: via object "Switch/Status:" The common object Switch/Status
receives the switch command and the current status becomes active
and is sent on the bus.
•
yes: via separate object "Status switch" An additional Status Switch
object is enabled. Using it a 1 bit telegram with the actual switch
status is sent on the bus.
Note
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 Switch object are lost and need to be reprogrammed.
If the object Switch/Status is used for switching and feedback,
particular care must be taken with the read and write properties (flags)
of the objects.
Unwanted switching actions can be triggered by the responses in a group
for other group participants. In a group with several Switch/Status objects
only one object should feedback the status in order to avoid mutual
interference of the participants due to feedback.
With the option yes:... two further parameters appear:
Send
Options: only after changing
if value change and triggered by switch command
Here you set if the response is sent with only after changing of the
object value or also with every value assignment of the object Switch
(option if value change and triggered by switch command), even if
the state does not change.
inverted
Options: no: 0 = OFF, 1 = ON
yes: 1 = OFF, 0 = ON
This parameter is enabled if the option yes:... has been selected
beforehand via the separate object Status switch.
With this parameter the response of the switching state can be
inverted.
With an inverted response the object Status switch features
the following values:
0 = lighting (output) is on
1 = lighting (output) is off
