Project design and programming
The preset function is used to retrieve a parameterised value e.g. in order to
implement lightscenes. In addition, the output value that is currently set can
be saved as a new preset value. The parameter window is enabled under
"A: Function".
There are two objects available for retrieving and storing presets. The
parameters for the objects "... preset 1/2" and "... preset 3/4" are identical;
the objects "... preset 1/2" are described in the following section by way of
example.
Explanations about the preset function can be found in section 3.2.3. Please
note the function diagram in section 3.2.6.
Parameter: "Reaction on preset1 (telegr. value 0)"
Preset1 is retrieved if the object "Call preset 1/2" receives the telegram value
"0". In this case, the output can trigger a defined state ("ON", "OFF" or "no
reaction").
One of the following functions can also be selected.
"restore old value before preset2" recreates the state before the last retrieval
of preset2.
Example:
With preset2, the lighting in a conference room is retrieved for a
presentation. When the presentation is finished, the lighting is
restored via preset1 to the state it was in beforehand.
"restore parameterised value of preset2" resets preset2 to the parameterised
value. This can be advisable if the preset can be stored via the bus (see
below).
Parameter: "Reaction on preset2 (telegr. value 1)"
This parameter sets which contact position is selected if the object "Call
preset ..." receives the telegram value "1".
Parameter: "Preset can be set via the bus"
The object "Set preset 1/2" is enabled via this parameter (parameter value
"yes"). It is used to store the current contact position as a preset value.
Telegram value "0" saves preset1 while telegram value "1" stores preset2.
If the special function "restore old value before preset2" or "restore
parameterised value of preset2" has been assigned to preset1, the telegram
value "0" is ignored.
