Functional description
Set the "Type of additional function" parameter in the "Groups - [x] group name" parameter node (x =
group number 1...32) to "Forced-control position function".
The forced-control position function is now enabled. The "Forced-control position " communication
object and the parameters of the forced-control position function become visible.
Configure the "Brightness for forced-control position active, ON" parameter in the "Groups - [x] group
name" parameter node to the response required if a forced control has been activated via the
communication object.
In case of the "Brightness value" setting, the DALI devices of the group will set the brightness
selected in the selection field when forced control has been activated. The selectable value cannot
fall outside the limits of the parameterized maximum and minimum brightness.
When the "No change" setting is selected, the bus mode of the group will be locked. However, the
devices will show no reaction and remain in the brightness state that was last set.
When the "Memory value" setting is selected, the brightness value will be set to the brightness value
that was active and internally stored prior to the switch-off (via the "Switching" or "Switching central
function"). This memory value is permanently stored so that the value is pre-defined to the maximum
brightness after the return of bus or mains voltage or after programming with the ETS.
Set the "Response at the end of the forced-control position" parameter in the "Groups - [x] group
name" parameter node to the required behaviour.
At the end of the forced-control position, the parameterized behaviour will be executed and the bus
control of the group re-enabled. When the "No change" setting is selected, the devices will show no
reaction and remain in the brightness state last set by the forced-control position.
When "Tracked brightness value" is selected: at the end of a forced-control position function, the
brightness state received during or set before the function can be resumed. If applicable, active time
functions will also be considered.
Updates of the forced-control position object from "Forced-control position active" to "Forced-control
position active" while tracking the forced switching status or updates from "Forced-control position
not active" to "Forced-control position not active" will cause no reaction. When updating from
"Forced-control position active" to "Forced-control position active", feedback telegrams will be
transmitted to the KNX/EIB according to the adjusted forced behaviour if feedback is enabled and
actively transmitting.
A group that has been disabled via the KNX/EIB can still be operated manually. At the end of a
manual control, the Gateway will re-execute the forced response for the affected groups if the forced-
control position is still activated at this point.
At the end of the forced-control position with "Tracked brightness value" setting selected": The
overridden functions of the DALI Gateway (switching, dimming, brightness value) will internally still
be processed during a forced-control position. Thus, newly received bus telegrams will be evaluated
and time functions will be triggered. The tracked states will be set at the end of the forced control. A
scene recall will not be tracked.
The current state of the object of the forced-control position will be stored in case of bus or mains
voltage failure.
