Updating the operating system 
Introduction 
If the operating system version of an HMI device is not compatible with the configuration, you 
need to update the operating system of the HMI device. Depending on the protocol used, the 
operating system on the HMI device is updated automatically upon prompting when the 
project is loaded. Thereafter, the loading continues. Otherwise, the loading of the project is 
canceled. In this case, you have to start the update of the operating system manually.  
Updating the operating system   
To update the operating system of an HMI device, connect the HMI device to the 
configuration PC. If possible, use the interface with the highest bandwidth, such as Ethernet, 
to make this connection.  
"Reset to factory settings"  
If the operating system on the HMI device is no longer functional, update your operating 
system and restore the factory settings on the HMI device. If the HMI device detects the fault 
itself, the HMI device automatically restarts in "bootstrapping" mode and issues a 
corresponding message.
