Input of values
Screen keyboard
The HMI device automatically opens the screen keyboard when you touch an I/O field to
enter values. This screen keyboard is also displayed to input of passwords for access to
protected functions. The HMI device automatically hides the keyboard when input is
complete.
Based on the configuration of the I/O field, the HMI device shows a screen keyboard only for
the input of numeric or alphanumeric values.
To enable the screen keyboard:
•
In Runtime, select an I/O field.
•
Depending on the configuration, you can activate or deactivate the automatic display of
the screen keyboard as required. This feature is useful when an external keyboard is
connected to the HMI device and the screen keyboard is not required.
The screen keyboard can be permanently displayed. Use the operating element provided by
the project engineer. The screen keyboard is now visible until closed by the operator, and
can also be used for input in other applications.
