General settings
General
The LEANtouch/SMARTtouch panel
can be used to send and save
lightscenes. Up to 20 EIB actuators
can be addressed via the memo
communication objects. The number
of memo objects available to the
panel is dependent on the type used
and on the setting “Number of objects
per lightscene”. This can be a
maximum of 20 (6 for LEANtouch)
objects.
The 1-byte communication object
“Lightscene number” is used for
retrieving lightscenes. The panel
receives one of 32 lightscene numbers
at this object. These lightscene
numbers can be retrieved internally in
the panel e.g. via a touch surface with
the appropriate settings or externally via
an EIB switch sensor.
If the panel receives a lightscene
telegram at its memo objects, it will
send switching or value telegrams in
sequence to linked actuators. The
“Telegram rate between two lightscene
telegrams” can be set. In the Powernet
version, this should not be set too low
as otherwise the bus load is
excessively increased. The preset value
of “1 s” should be sufficient and should
be changed if necessary. In the
Twisted Pair variant, the telegram rate
is not critical and can be lowered if
necessary.
Lightscene
The size of the memo communication
objects can be adapted to switch,
dimming or shutter actuators. This
means that if a switch or shutter
actuator should be addressed via a
memo object, the object is 1 bit. If a
dimming actuator should be
addressed, the object is 1 byte. The
bit size is defined individually for each
memo object via the parameter
“Actuator type”.
The LEANtouch/SMARTtouch panel
software displays various options
depending on the selection.
With the selection “Switch or shutter
actuator”, it is possible to set “Off/Up”
or “On/Down”. Alternatively, an
actuator can also be “Inactive” within
a scene.
If “Dim actuator” is set as the actuator
type, percentage values of 0% to
100% can be set in increments of
10%.
Saving lightscenes
If the end customer would like to carry
out changes to the predefined
lightscenes, he can do this without any
great effort. He must first set all the
lamps and/or shutters to the required
position i.e. he dims or moves the
individual components via separate EIB
switch sensors or via the touch surfaces
of the panel. He then triggers a
lightscene storage telegram with a long
operation (> 3 s) of a lightscene touch
surface or an additional lightscene
switch sensor. This telegram is
received at the object “Lightscene
number”. The individual memo objects
now send read requests to the linked
EIB actuators. If the read flag is set for
these objects, the actuators send back
their current values in response
telegrams. These values are stored in
the panel and are not lost in the event
of a bus voltage failure.
If changes are carried out on the
LEANtouch/SMARTtouch panel and
then programmed in the panel,
lightscenes that have been stored by
end customers are likewise not lost by
default. This behaviour can also be
modified via the parameter “Overwrite
lightscene settings at download”. All the
lightscenes can thus be reset to the
preset options which were carried out
with the panel software.
