5.3 Operation with external keyboard/mouse
Connection
An external keyboard or mouse can be connected to the USB interface on the HMI device.
Connection and disconnection are possible during normal operation of the HMI device (”hot
plug in/out”).
Operation of the HMI device via an external keyboard/mouse is particularly recommended
during the commissioning and test phases.
Notice
Commercially available USB devices do not normally meet the higher industrial demands
relating to interference resistance and can have negative effects on the HMI device.
USB mouse:
Use a standard mouse.
USB keyboard:
Use a standard keyboard with a USA/International keyboard layout. Operation of the
configured function keys is not possible via the external keyboard.
Operation
Operation of the HMI device via a mouse is only slightly different from operation using the
touch screen. After connecting a mouse, the mouse pointer
appears on the screen.
When the mouse pointer is positioned on an operable button, the mouse pointer symbol
changes
.
Caution
When using a keyboard unit, do not operate the integrated membrane keyboard and
external USB keyboard simultaneously. You may trigger an unintended action.
