In this parameter window presets settings can be made.
What is a preset?
The presets are used to recall predefined brightness values via
1 bit telegrams.
Four presets are available per output. The presets with an even
number (2 and 4) are recalled by a telegram with the value 1,
the presets with an odd number (1 and 3) are addressed by a
telegram with the value 0. Separate objects are available for recalling
and for saving / setting of a preset brightness value.
With the recall of presets; the maximum and minimum values as set
in the parameter window
limits are set when the maximum and minimum values are overshot or
undershot. At a brightness value of 0, a switch off is always executed,
independently of the parameter Allow switching off via brightness
value parameterised in the parameter window X: Value.
A preset recall has no effect on the output with parameterised
staircase lighting function.
A preset save command via object Set preset 1 and 2 is implemented,
i.e. at the time as the save command the current brightness value of
the output is saved as a new preset value.
The reaction to the preset recall with parameterised slave mode can
be parameterised in the
reaction parameterisation a preset recall is ignored with active slave
mode. A preset save command is executed. The parameterisation
Slave mode can be deactivated has the effect that the preset recall is
implemented and the slave operation discontinued. If simultaneously
the preset command restore value before first preset call is
parameterised, slave operation is reactivated. Otherwise slave
operation is activated by the object Activate slave mode.
With the first recall of a preset the current state (brightness value) is
stored. At the same time; it does not matter which of the four presets
are recalled. Further preset recalls do not initiate a renewed save.
