Clean screen for Touch HMI devices
The touch screen of the HMI device can be cleaned when it is switched on and a project is
running. An operating element must be available in the project that can be used to call the
"clean" screen. Once the clean screen is activated, touch screen operation is locked for a
configured period of time. The time the touch screen is locked can be set between 5 and 30
seconds. The time remaining for the lockout is indicated by a progress bar.
