Operator control functions
The functions assigned to the function keys, the handwheel, the key-operated switch and the
illuminated pushbuttons are determined during configuration. The above-mentioned operator
controls do not function outside of a project.
Evaluation and selection of the operator controls
The following information can be transferred between the HMI device and the PLC:
● Direction pulses of the handwheel
● Status of the function keys
● Status of the key-operated switch
● State of the illuminated pushbuttons
● State of the function keys and illuminated pushbutton LEDs
There are two ways of transmitting information:
● Direct keys
● System functions of WinCC flexible
Standard input unit
The standard input unit on the HMI device is the touch screen. All operating elements
required for touch operation are displayed on the touch screen once the HMI device has
started.
NOTICE
Damage to the touch screen
Never touch the touch screen with pointed or sharp objects. Avoid applying excessive
pressure to the touch screen with hard objects. Both these will substantially reduce the
useful life of the touch screen and even lead to total failure.
Always operate the HMI touch screen with your fingers or with a touch pen.
Damage to the keyboard
Pressing the keys with a hard instrument considerably reduces the service life of the key
mechanism.
Always use your fingers to operate the keys of your HMI device.
