Application “2-button switching”
With the application "2-button switching”, a switching telegram is sent when the button is
actuated and/or released. Here it does not differentiate between whether the button is
operated on the left or right side. In each case, the application makes a separate set of
parameters and communication objects available for the right and left side of the button.
It also makes a switching function possible via one side of the button and assigning a
further "button-oriented" function to the other side of the button.

Alternating on/off
The "Working mode of the button for switching" is used to specified whether an operation
of the left or right side of the button will send out an ON or an OFF telegram. Alternatively,
for the selection "Alternating on/off", you can switch between switching on and switching
off for every operation that triggers a switching telegram. This means that after a switch-
on telegram is sent out (or received), a switch-off telegram is sent out for a renewed
operation. After it is operated again, a switch-on telegram is sent out.
If a switching telegram is trigger by operation of the button, this will be sent out on the 1-
bit communication object "Switching".

Application “2-button dimming”
The push-buttons have two communication objects for switching and dimming. A
distinction is made between a short (switching) and long (dimming) press of the button. A
differentiation is made between whether the 1st or 2nd button is actuated. The parameter
"Working mode of the buttons for switching and dimming" is used to set whether the 1st
button or 2nd button switches on or off or whether it is dimmed brighter or darker.
12.18.1
Common parameter - Duration of long operation (ss:ms)
Options
Time input from 0.3 to 3.0 seconds
A differentiation can be made between a short or long operation of the button. With a
short operation of the button, the next level forward is switch to in each case. With a long
operation, the first level is activated. Thus, with a long button press a jump back from
every position to the first level is possible, without having to run through the remaining
levels.
