Art. No. SC 1000 KNX
(approx. 1s) if this was enabled by parameter configuration in the ETS. Using the keyboard, any
value defined by the "Function" parameter within the range (0...255" / "0...100%") can be
entered numerically and applied by pressing the
>
button. After applying the value, it is
transmitted to the bus and saved permanently in the device memory. Only an ETS programming
operation resets the value to the ETS configuration.
The entry can be terminated without transmitting any value by touching the sensor surface
x
in
the keyboard.
i
It is only possible to specify a value via the keyboard in selection operation on the room or
function pages.
Objects
A channel of the function "1-byte value transmitter" has up to 2 KNX communication objects...
-
"D.Output channel x - value transmitter 1-byte" (1-byte transmitting):
Value telegrams (0...255) are transmitted to the bus via this object after pressing the
sensor element. This can cause, for example, a limiting value object, brightness value
object or blind position object to be activated.
This object is not visible when the KNX channel only works as a display function.
-
"D.Input channel x 1-byte value transmitter feedb." (1-byte receiving):
Through this object the device can receive a value feedback that an activated actuator
transmits, for example. The status value, status icon and bar graph for the value
visualization are influenced as a result. Consequently, the feedback object must always be
configured properly so that the status indications of the channel element work correctly.
The feedback of the value must be transmitted by the "actively transmitting" actuator.
If the activated bus device does not have a feedback function, the object "D.Input channel x
- 1-byte value transmitter feedb." can be linked to the object "D.output channel x - 1-byte
value transmitter" via an identical group address.
i
The objects always handle the value range "0...255". The configured "function" in the ETS
defines how the transmitted or received values of this area are to be interpreted. In the
setting "Value transmitter 0%...100%", the values are interpreted on the basis of the KNX
data point type 5.001 (Scaling). The decimal data values 0...255 are then evaluated as
percentages 0...100 %. In the case of "Value transmitter 0...255", no particular
interpretation takes place. In this case, the received feedback values are evaluated directly
in the decimal value range 0...255 in compliance with KNX data type format 5.010
(ValueUcount).
i
The status elements of the channel are influenced by the object "D.Input channel x 1-byte
value transmitter feedb." . In addition, a value recall by sensor operation or by entry via
keyboard also influences the status elements. During a value recall, the status elements
are updated according to the recalled value regardless of the current feedback value. The
display elements first react again to the feedback object value after a value recall by
operation. As a result, this may cause a leap in value in the status indication when returned
values vary from the preset value.
