Feedback for switching status and brightness value:
The DALI Gateway can track the current switching status and brightness value of a DALI group via
separate feedback objects. It can also transmit them to the bus if the bus voltage has been switched
on.
The following feedback objects can be independently enabled for each DALI group...
–
Switching status feedback (1-bit),
–
Brightness value feedback (1-byte).
The Gateway will compute the object value of the feedback objects every time switching or dimming is
taking place. Even if a group is controlled via manual control or the scene function, the Gateway will
track the switching status or the brightness value and update the feedback objects.
The switching status feedback object will be updated during the following events...
–
immediately after switching on a DALI group (if applicable, only after a On-delay has lapsed and at
the beginning of a SOFT-ON dimming operation / applies also to a Staircase timer function),
–
immediately after switching off a DALI group (if applicable, only after a Off-delay has lapsed and at
the beginning of a SOFT-Off dimming operation / applies also to a Staircase timer function),
–
immediately after switch-off by the automatic Shutoff function,
–
at the beginning of a dimming operation when increasing brightness (relative increase of brightness
or brightness value = 1...100 %) of a DALI group,
–
at the end of a dimming operation when increasing brightness of a group (brightness value = 0 %),
–
only if the switching status changes during “Normal operation” (thus not during dimming without
changes to the switching status, e.g. from 10 % to 50 % brightness),
–
during updates of the switching status from “OFF” to “OFF” if the DALI group has already been shut
off,
–
always at the beginning or the end of a disable or forced-control position function (even if it does not
cause the switching status to change),
–
always at the return of bus/ mains voltage or at the end of a programming operation with the ETS (if
applicable, even if time-delayed).
The brightness value feedback object will be updated during the following events...
–
at the end of a relative (4-bit) or an absolute (1-byte) dimming operation.
–
immediately after switching on a DALI group if switch-on brightness has been set (if applicable, only
after an On-delay has lapsed and at the beginning of a SOFT-ON dimming operation / applies also to
a Staircase timer function),
–
immediately after switching off a DALI group (if applicable, only after a Off-delay has lapsed and at
the beginning of a SOFT-Off dimming operation / applies also to a Staircase timer function),
–
immediately after switch-off by the automatic Shutoff function,
–
only if the brightness value changes during the ‘normal operation’ (in case a preset brightness value
has been exceeded or under-run the maximum or minimum brightness by external relative or
absolute dimming, the Gateway will update a brightness value feedback according to the maximum
and minimum brightness),
–
when updating the switching status from "ON" to "ON" or from "OFF" to "OFF",
–
during each scene recall (even if it does not cause the brightness value to change),
–
always at the beginning or the end of a disable or forced-control position function (even if it does not
cause the brightness value to change),
–
always after the return of bus/ mains voltage or at the end of a programming operation with the ETS
(if applicable, even if time-delayed).
