Art. No. SC 1000 KNX
4.2.4.1.9 Channel function "1-byte value transmitter"
With the channel function "1-byte value transmitter" telegrams in compliance with the KNX data
types 5.010 (unformatted / 0...255) and 5.001 (Scaling / 0...100%) can be transmitted to the
bus. The activation of other bus devices enables the user, for example, to execute limiting value
presettings or presettings for current counter statuses.
Since the data format is identical, it is also possible as an alternative or supplement to the
channel function "dimming (brightness value)" or "Venetian blind/shutter (position)" to activate
dimmer actuators more easily (via brightness value specification) or blind and shutter actuators
(via position value specifications). Here - as an example - static brightness or position values
can be configured and recalled by sensor surface operation. Such an operation is appropriate
when slider, value adjustment by a long button-press or visualizations of slat positions are not
required. The character of the status icons support such use of the channels and make it
possible to adapt to the activated KNX actuator.
A KNX channel "1-byte value transmitter" has a display element and sensor surface in the
graphic interface for operation. The display area and sensor area, depending on the existing
operation concept, are combined into one surface (direct operation) or distributed on two
surfaces (selection operation). The sensor element is always executed as a push-button
function and does not distinguish between any short and long operations.
A sensor operation triggers the value telegram configured in the ETS. The ETS "Function"
parameter determines the data format of the object and defines which value range the channel
function uses. The channel can optionally process integers from 0…255 or values within a
range of 0…100%. The scaling of the status indications also adapts itself depending on this
setting.
In addition to recalling values by operation of the sensor surface, it is possible to use a
keyboard for presetting the value . As a result, it is possible optionally to permanently change
the value that was originally preset in the ETS and thus adapt it at any time.
