The configuration PC and HMI device are connected. 
If you have connected the HMI device directly to the configuration PC using the  
PROFINET (LAN) interface, you have to assign an IP address to the HMI device afterwards. 
If Windows XP is installed on the configuration PC and you have connected the HMI device 
to the configuration PC via USB, you will be prompted to install the USB driver. You can find 
the USB driver in the installation folder of WinCC.  
 
Note 
Updating the operating system  
If there is no serviceable HMI device image on the HMI device, you can only update the 
operating system by restoring the factory setting. When restoring the factory
 settings, 
connect the PC to the HMI device using the PROFINET (LAN) interface.
 
Connecting multiple HMI devices in succession 
If you connect more than one HMI device with the same IP address in succession to a single 
configuration PC, you need to ping the 
configuration PC once from the HMI device on each 
changeover of the HMI device.
