Operating a project with an external keyboard
An external keyboard can be used to operate a project in exactly the same way as with the
HMI keyboard or screen keyboard.
Note
The function keys of the external keyboard are disabled.
Use the other keys of the external keyboard, which correspond to the HMI device keys
in the description.
Operating a project with an external mouse
An external mouse can be used to operate a project in exactly the same way as with the
HMI touch screen. Click the described operating elements with the mouse.
Unintentional actions
CAUTION
Do not carry out several operations simultaneously. You may otherwise trigger
unintentional actions.
• With touch control:
Always touch only one operating element on the screen
• With key control:
Do not press more than two keys simultaneously
Observing the plant documentation
Some operations with the project may require in-depth knowledge about the specific plant on
the part of the operator. Proceed with caution, for example, when you use jog mode. Further
information on this may be available in your plant documentation.
Operation feedback from operating elements
The HMI device provides operation feedback as soon as it detects that an operating element
has been selected. This operation feedback is independent of any communication with the
PLC. Therefore, this operation feedback does not indicate whether the relevant action is
actually executed or not.
