●  Direct keys 
The following objects can be configured as direct keys:  
–  Buttons 
–  Function key 
–  Screen number 
When screen numbers are used, the configuration engineer can configure direct keys 
on a screen-specific basis. 
 
  You can only use direct keys if there is a connection over PROFINET IO. 
  Direct keys create an additional base load for the HMI device. 
You can find additional information about configuring in the online help of WinCC (TIA Portal) 
under "Visualizing processes > Communicating with PLCs".  
 
Setting the transfer mode 
If you do not only want to start transfer from the Mobile Panel, you can configure a specific 
operating element. Configure the "SetDeviceMode> Load" system function for an event of an 
operator control, for example, for a button. If required, configure the corresponding data 
channel on the configuration PC.  
You can find more information on this topic in the online help of WinCC (TIA Portal).  
 
Changing the operating mode 
You can configure an operating element to allow you to change the operating mode on the 
HMI device during runtime. Configure the "SetDeviceMode" system function for an event of 
an operator control, for example, for a button. The following operating modes are available: 
"Online", "Offline", "Load". The "Load" operating mode in the configuration software 
corresponds to the "Transfer" mode on the HMI device. 
If required, configure the corresponding data channel on the configuration PC.
