12.12.1
Common Parameter – Duration of long operation (ss:ms)
Options
Time input from 0.3 to 10.0 seconds
A short and long operation can be differentiated between for the operation of the button.
For a short operation of the button, a preset light scene is call up on the 1-byte
communication object "Light scene number". For a long operation, a command for storage
of the preset light scene is sent out on the same communication object.
Via the "Duration of long operation (ss:ms)", the time is specified after which a long button
press is recognized and a command for the light scene storage is sent out instead of the
light scene number. Any time from 0.3 to 10.0 seconds can be set. A typical value, after
which a button triggers a storage for a long press is 5 s.
12.12.2
Common Parameter – Storage function light scene
Options
Deactivate
Activate
Within the 1-byte value, a memory bit is set in addition to the light scene number. If a light
scene module receives this 1-byte value, the module can identify the affected light scene
and trigger a storage procedure. Read requests are sent to all connected actuators that
in turn answer with their current communication object values. The answers are saved by
the light scene module and are sent out again for every future receipt of the light scene
number.
12.12.3
Common Parameter – Number of light scene
Options
1 to 64
In the parameter "Light scene number", an arbitrary light scene number from 1 to 64 can
be specified which can be sent out via the 1-byte communication object "Light scene
number" for operation of the button.
The button only serves as light scene extension unit, i.e. the button only calls up the light
scene number. The individual values for the dimming actuators or blind actuators to be
adjusted are stored either in the actuator itself or in connected light scene.
A light scene module will receive the light scene number and subsequently send the
stored light scene values consecutively to the connected actuators.
