Operating a Project
8.1 Overview
Caution
Do not use any pointed or sharp objects when operating the touch screen. Otherwise this
may damage the plastic membrane of the touch screen.
The following provides instructions for operating a project with the touch screen and the
keyboard.
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 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 with the HMI
touch screen. Click the described operator controls with the mouse.
Unintentional Actions
Caution
Do not carry out several operations simultaneously. You may otherwise trigger unintentional
actions.
• Operation using the touch screen:
Always touch only one operator control on the screen.
• Operation using the keys:
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. It is therefore important to take special care, for example, in typing
mode. Further information on this may be available in your plant documentation.
Operation Feedback from Operator Controls
The HMI device provides optical feedback as soon as it detects that an operator control has
been selected. The operator control receives the focus and is selected. This selection is
independent of any communication with the PLC. Therefore this selection does not indicate
whether the relevant action is actually executed or not.
The configuration engineer can also configure the selection of an operator control so that it
deviates from the standard. Further information on this may be available in your plant
documentation.
