Inexpensive but lower-performance Windows PCs, rugged on-site devices (e.g. SIMATIC Thin Clients) and mobile clients (PDA – Personal Digital Assistant) can be connected via thin client solutions with Microsoft Terminal Services. Only minimum requirements are placed on the hardware here because the entire application, i.e. including the WebNavigator client, runs on the terminal server.
Siemens offers rugged SIMATIC Industrial Thin Clients as operator terminals with high-resolution wide screen touch displays. These are optimally suited for use in harsh industrial environments.
Flexible remote diagnostics
The WebDiagnostics client was designed for maintenance and service of widely distributed plants. In this case, the Web licensing is made for a diagnostic client locally on a service computer instead of on the system servers. Through the diagnostic client, the service technician has secure access to any number of plants that have a WebNavigator server.
Dedicated Web server and Web server farms with load balancing
The WinCC Web Server can also be configured on a WinCC (SCADA) client for even more security and availability. Advantages of this solution:
Web server farms allow the number of Web clients to be increased as needed.
