Operation acknowledgement
As soon as the touch panel detects valid contact with a touch element, it responds
by displaying a visual acknowledgement. An acknowledgment is independent of
communication with the PLC. It is not an indication of the required action actually
having been executed.
The type of visual acknowledgement is dependent on the operating element
touched:
Buttons
In the case of 3D–effect configurations, visual representation is distinguished
according to the statuses
touched
and
untouched
. Examples of representation
are illustrated below by means of the Status button.
UntouchedTouched
Input fields
After an input field has been touched, the system keyboard illustrated in figure
4-1 appears as the operation acknowledgement.
