Art. No. SC 1000 KNX
scene recall. The setting specifies how much time must pass after the first scene telegram
before the second is transmitted. After transmission of the second scene telegram, the
configured time must again pass before the third is transmitted and so forth... The transmit
delay for the scene telegram of the first output starts immediately after the scene has been
recalled.
The transmit delay between telegrams can also be deactivated (setting "0"). The telegrams are
then transmitted at the shortest possible time interval. In this case, however, the order of the
telegrams transmitted can deviate from the numbering of the scene outputs.
i
When a new scene recall (also with the same scene number) occurs during a current
scene recall - even in consideration of the pertaining transmit delays - the scene
processing started first will be aborted and the newly received scene number will be
processed. A running scene is also aborted when a scene is being stored!
i
During a scene recall - even if delayed - the sensor surfaces of the device are normally
operational.
Storing scenes
For each output of a scene, the user can define a corresponding scene value in the ETS which
is then transmitted to the bus during a scene recall. During the ongoing operation of the system
it may be necessary to adapt these preset values and to save the adapted values in the device.
This can be ensured by the storage function of the scene control.
The value storage function for the corresponding scene number is enabled with the parameter
"Permit storing ?" ("Yes") or disabled ("No"). When the storage function is disabled, the object
value of the corresponding output is not sampled during storage.
A scene storage process can be initiated in two different ways...
-
by a long press of a control surface configured as "scene extension",
-
by a storage telegram to the extension object.
During a storage process, the device reads the current object values of the connected
actuators. This is carried out by means of eight read telegrams (ValueRead) addressed to the
devices in the scene which return their own value (ValueResponse) as a reaction to the request.
The returned values are received by the device and taken over permanently into the scene
memory. Per scene output, the scene control waits one second for a response. If no answer is
received during this time, the value for this scene output remains unchanged and the next
output is scanned.
In order to enable the device to read the object value of the actuator addressed when a scene is
stored, the read flag of the corresponding actuator object must be set. This should be done only
for one actuator out of an actuator group so that the value response is unequivocal.
The stored values overwrite those programmed into the device with the ETS.
i
A storage process will always be executed completely and cannot not be aborted before it
has ended.
i
It is not possible to recall scenes during a storage process, but the sensor surfaces still
remain operational.
