8.18.4.3 WinCC "System Info" channel
Introduction
The WinCC "System Info" channel is used to evaluate system information from server PCs. 
The channel does not require hardware because it directly accesses the system information 
of the server PC on which it is installed. 
Note
Only the system information from a single server can be represented or evaluated on a client.
