System keys – control keys
Standard input device at the HMI device is the keyboard. This is basically composed of two
key groups:
●
Soft keys
F1 to F4
The soft keys can only be assigned within a project and do not have any function in the
Loader menu.
●
System keys
These include the control keys, for example.
NOTICE
Unintentional actions
Unwanted actions may be triggered if the operator unintentionally actuates several keys
at once.
Never press more than two keys simultaneously.
Keyboard damage
Operation of the keys with hard, pointed or sharp objects or hard impact may lead to a
considerable reduction of the service life and even to complete failure.
Always use your fingers to operate the keys of your HMI device.
