(E) First part of the control surface as button with a single actuation point
(F) Second part of the control surface as button with a single actuation point
(G) Actuation point for button X (X = 1, 3, 5, 7)
(H) Actuation point for button Y (Y = 2, 4, 6, 8)

Depending on the button arrangement configured in the ETS (see page 144-145), the
buttons and thus the actuation points of a control surface can be arranged either top /
bottom or left / right for double-surface operation of the buttons. The example illustration
shows a top / bottom button arrangement. With single-surface operation the button
arrangement cannot be adjusted, because there is only one button per control surface.
In single-surface operation, the entire control surface is evaluated only as a single "large"
button. This button is configured independently of the other buttons or rockers of the push
button sensor and can fulfil various functions (e.g. Switching: TOGGLE).

An operating area is always created in the ETS as a button pair. However, because in
single-surface operation only one button functionally exists, the second button of the button
pair has no function and is physically not present. During configuration in the ETS it is
shown as button without any further button parameters. Only the status LED of this button
which is physically not used can be configured separately and if needed also activated via
its own communication object.
The physically present button which is to be evaluated in single-surface operation is always
created as a button with an uneven button number. If, for example, the first operating area
of a push button sensor is configured to single-surface operation, then button 1 can be
configured in the ETS. Button 2 is then the physically not present button without
parameters.
Button arrangement
On the parameter page "Operation concept of extension module", it is possible to set separately
for each button pair of a control surface configured in the ETS as a rocker function or as a
double-surface push-button function how the buttons are to be arranged on the surface, i.e.
where the actuation points are located.
Here the parameter "Button arrangement" specifies the actuation point evaluation.
