Overview 
Operator input options 
You can use the touch screen to make entries. 
 
 
Never carry out multiple operations on the Mobile Panel at the same time. You may trigger 
unintentional actions that could cause material damage. 
Never press more than one operating element on the display at once. 
This section describes the operation of a project with the touch screen. 
Observing the system documentation 
Some operations with the project may require in-depth knowledge about the specific system 
on the part of the operator. Exercise the necessary care if the plant is in setup mode, for 
example. Please refer to your plant documentation for additional information. 
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 
controller. Therefore, this operation feedback does not indicate whether the relevant action is 
actually executed or not. 
Optical feedback from operating elements 
The operating element receives the focus and is selected. The configuration engineer can 
also configure the selection of an operating element so that it deviates from the standard. 
Refer to your system documentation to find any additional information on this topic.
