Embodiment Construction

[0020] figure 1 The automation system of has a client 1 with a browser 3 . The browser 3 can be a common Internet browser, such as Netscape Navigator or Microsoft's Internet Explorer. By entering a so-called Uniform Resource Locator (URL), the user can call up a specific web page 8 . In this case, the web page 8 can be used to visualize certain subsystems of the installation regulated by the automation system.

[0021] Here, the web page 8 typically includes one or more display areas for displaying current parameter values, such as pressure, temperature, liquid level and other sensor measurements or mechanical parameters.

[0022] Client 1 is connected to server 4. Among them, the TCP / IP protocol can be used as the protocol for the connection between the client 1 and the server 4 . In this case, a computer network like the Internet can be set up between the client 1 and the server 4 .

[0023] The server 4 is connected to a memory 7 which contains the URL of the web page 8

Abstract

The invention relates to an automation system and a method for visualizing a system with a client (1) for displaying a web page consisting of data fields for displaying parameter values, comprising a processing unit (2) for storing actual parameter values. The modified parameter values can be interrogated by a client (1) by cyclical polling. Only the modified parameter values are transmitted to the client (1) in an associated script and interpreted by the browser (3).
