In addition to the standard WebNavigator licensing, there is the "Diagnostics Client" with identical functionality but different licensing. It is especially suitable for the following applications:

• Remote diagnostics/operation of several unmanned WinCC server stations
• Central control rooms that monitor several web servers via one user interface
• Maintenance personnel who require guaranteed access to the server at any time, regardless of the number of users already logged on to the server.
  On the server side, only one WebNavigator Diagnostics Server license or, alternatively, one Standard WebNavigator license is required.
