8 The CP 443-1 Advanced as Web Server: HTML
Process Control
The CP 443-1 Advanced provides you with the function of a Web server for access
using a Web browser.
The CP 443-1 Advanced provides an additional memory area for storage of files.
This area is used to store HTML pages and S7 applets.
HTML pages are used to indicate and display information in a Web browser. S7
applets are Java applets specially written for SIMATIC S7 and that are used to
allow write or read access to the S7-CPU.
When the CP 443-1 Advanced is supplied, there are HTML system pages, S7
applets, S7 beans and further information in the file system.
Please note the following special features when operating IT functions:
Note
The data exchange for productive communication (S7 connections +
SEND/RECEIVE connections) always has a higher priority than data exchange
with the Web browser. This can lead to delays in the HTML process control in the
Web browser.
Web Browser
To access the HTML pages on the CP 443-1 Advanced, you require a Web
browser.
The following Web browsers are suitable for communication with the CP 443-1
Advanced (other browsers also possible):
S Netscape Communicator (recommended version: 4.7 or higher)
S Internet Explorer (recommended version: 5.0 or higher)
These Web browsers support all the requirements necessary for the
implementation of the IT functions (Java reference implementation − Java
Development Kit) 1.1.x is supported) in conjunction with the CP 443-1
Advanced.
You will find these Web browsers, information and addons on the Internet.
