4.2.4.2.4 Rotary knob function 1-byte value transmitter
With the rotary knob 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 KNX devices enables the user, for example, to make limiting
value presettings or presettings for current counter statuses. Since the data format is identical, it
is also possible 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 rotary knob operation.
Depending on the direction of the rotary knob (clockwise or anticlockwise), different values can
be transmitted to the bus via a shared communication object (figure 21). The values can be
parameterised in the ETS. It is possible optionally to make a value adjustment. In this case, only
one value can be configured in the ETS for both directions of rotation, which can then be
adjusted during regular operation of the device by a clockwise or anticlockwise movement
(figure 22).
