The parameter
LED lighting
permits, for its part, defining the behaviour of the
LED corresponding to the button. The parameterization is analogous to that
already described for the previous case, although the lighting state depends here
on the “[Xi] 2-byte value (unsigned int)”.
2-byte constant (float)
:
permits that short touches on the button trigger the
sending of a 2-byte floating point value (-25.0 to 90.0) through the “[Xi] 2-byte
value (float)” object.
The parameter
LED lighting
permits, for its part, defining the behaviour of the
LED corresponding to the button. The parameterization is analogous to that
already described for the previous case: “Regular” (the LED will stay “ON” for an
instant when the button is touched) or “State-dependent” (the LED will stay “ON”
when the value of the “[Xi] 2-byte value (float)” object equals the numeric value
parameterized, and “OFF” in any other case).
Dimmer
:
permits performing light system dimming by using a sole touch
button and two communication objects: “[Xi] Light On/Off (Toggle)” (1-bit, linked
to short touches) and “[Xi] Light dimming (Toggle)” (4-bit, linked to long touches).
Having only one button to perform these functions implies commuted responses
on button touches, as in the following example:
Example: after the first touch on the button, a switch-on order (“1”) will be
sent through the “[Xi] Light On/Off” object. A later short touch on the same
button will cause the sending of a switch-off (“0”) order through the same
object. After that, a further short touch will cause the sending of the value “1”
again, and so on with the following touches.
Also step dimming implements a commuted behaviour – if a long touch caused
the sending of an order to increase the light level, the next touch will send an
order to decrease it; and analogously for the inverse case. However, after a
switch-off through a short touch, the next long touch will always imply an order to
increase the light. Similarly, if the last (short) touch caused a switch-on, the next
long touch will necessarily cause a decrease in the light level.
