Figure 25: Example of the function "Value transmitter 0…255" with value adjustment with
overflow
("Value transmitter 0…100 %" is basically the same)

During a value adjustment up to the limits of the adjustable range, the limiting values ("0" or
"255" / 100%") are always transmitted. To ensure that the original starting value (here
"247") can be reset to the adjustment direction on resetting with a change, the first value
jump is not equal to the preset step width (here "255" -> "252") in the case of a value
adjustment without overflow. In the case of a value adjustment with overflow, an
adjustment is always made based on the step width (here "255" -> "250" -> "245") after
reaching the limiting values during a new adjustment in both adjustment directions. An
adjustment to the original value does not take place automatically here.
Value transmitter comfort 0...255
This function allows the operation of the rotary knob for transmitting values dependent on speed
and rotation angle. Here, depending on the speed of rotation, a value adjustment is possible by
small and large step widths, thereby allowing the brightness of a lighting system to be set finely
and gradually. During a fast rotary movement, the size of the step width is also specified by the
rotation angle. The direction of rotation specifies the direction of value adjustment.
In the function "Value transmitter comfort 0…255", a value adjustment is normally executed.
During an operation - depending on the direction of rotation - the value in the communication
object "Feedback value" is increased or decreased by the effective step width and transmitted
again to the bus via the object "value". In this way, for instance, it is easily possible to control a
lighting system via a dimmer actuator. The object "value" of the rotary knob is connected to the
brightness value object of the dimmer actuator via a group address. The object "Feedback
value" of the rotary knob is - if the actuator has a separate 1-byte feedback object" - linked to
the actuator communication object "Feedback brightness value" via a second group address.
