Challenge + Solution

Web Navigator – The client requires that the incineration plant located in Huizhou China be monitored from their office in Hong Kong via in-house intranet. This is made easy using the WinCC Web Navigator option – A Web server with the WinCC software and Web client enables operator control and monitoring of the WinCC project via an internet browser with ActiveX support. This has proven invaluable to the client during the startup and ongoing operation of the facility.
