so they can both send regulation orders and receive the status from the regulator)
named:
➢
[Pn][Bi] Red Channel
➢
[Pn][Bi] Green Channel
➢
[Pn][Bi] Blue Channel
Control orders will consist in sending the light level (as a percentage) of the
different channels through the corresponding objects.
If the second option is selected, only one 3-byte object will be enabled:
➢
[Pn][Bi] RGB Colour
In this case, the light levels of the three channels are sent (and received)
concatenated into the above 3-byte object.
Note
:
if statuses are received while the luminaire performs a regulation, this
control may become hardly serviceable until such regulation ends
.

Right Button
: permit selecting the icon that will be displayed
inside the buttons in the box.
Regarding the RGB control boxes themselves, a central label will permanently show, as
a percentage, the current light level (which is determined by the channel with the highest
current light level). This
indicator
gets updated automatically as the user interacts with
the box, but is also conditioned by the values received from the bus through the already
described objects.

Moreover, two buttons can be found in the box:
Short-pressing on the left button it permits commuting between a total absence
of light in the three channels, and their respective states previous to the switch-
off.
Long
-pressing it, on the other hand, will make the device send a 4-bit
dimming order through object
[Pn][Bi] Intensity Dimming
, analogously as in a
light dimming control (see h) in section 3.6.2.3).
