Clean screen for Touch HMI devices
This chapter is valid for the Comfort INOX 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.
Note
Unintentional responses
When cleaning the touch screen, an unintentional response in the controller can be triggered
by touching keys.
Always open the clean screen or switch off the HMI device before you clean the touch screen
while the system is running.
Cannot be operated when the clean screen is active
When the clean screen is active, operations on the HMI device are not possible.
Wait for the period of the clean screen to lapse. Then you can operate the system again with
the HMI device.
No clean screen with HMI devices with touch screen and function keys
The clean screen is not available for HMI devices with touch screen and function keys. In this
case, configure a screen without operating elements, for example.
