Entering Values Using the Touch Screen
Overview
Screen Keyboard
When you touch an operator control requiring input on the HMI touch screen, a screen
keyboard appears. The screen keyboard is displayed in the following cases:
• An IO field is selected for input.
• A password must be entered for accessing a password-protected function.
The keyboard is automatically hidden again when input is complete.
Based on the configuration of the operator control, the system displays different screen
keyboards for entering numerical or alphanumerical values.
Note
The screen keyboard display is independent of the configured project language.
General Procedure

Proceed as follows:
1. Touch the desired operator control within the screen.

found with the respective operator control.
Examples:
– I/O field: Enter numerical, alphanumeric or symbolic values in the IO field.
