Functional detail
6.4.6.1
Feedback
When the feedback is enabled, 2 communication objects are available for reading by other devices on the
bus: an object indicates the current state of ON / OFF, the other object indicates the current percentage of
dimming. These objects report the actual state of the logic output, which is probably different from that set by
the command, as it includes the effect of any other functions currently active.
When these communication objects are defined, they are transmitted automatically at any status change, so
that events can be generated at any actual change of the output. It is also possible to configure the objects,
so that the transmission also takes place at regular intervals.
When the power-on and / or power-off mode are set to
soft
, the communication object that
indicates the current position of dimming provides as feedback the actual value that will reach at
the end of the ramp. Similarly during dimming, the final value (maximum or minimum) is provided
as feedback and, only after the release of the dimming command, the dimming percentage
actually achieved is provided as feedback.
6.4.6.2
Time delay
The actual change of state of an output can be set to take place after a configurable delay from the change
of the value of the corresponding communication object; this applies both to the on-off and the off-on
transitions, each with its individually configurable delay value (T
on
and T
off
respectively).
These delays are applied to the transitions through a direct command and/or logical objects, but not to those
caused by other functions (e.g.: staircase or scene).

Staircase function
This function is intended to provide a simple and flexible way to manage the switching of staircase lights.
These have following peculiar requirements:
