The CP as Web server

Web diagnostics

The CP provides you with the function of a Web server for access using a Web browser. The

CP provides HTML pages for Web diagnostics.

With the following address, you have access to Web diagnostics:

http:\\<IP address of the CP>\diag

Diagnostic buffer entries are output in English on the diagnostic pages. This is not influenced

by the language selected for display of the Web pages.

For detailed information on Web diagnostics, refer to the general Part A of this manual /1/.

Please note the following special features when using Web diagnostics:

Note

Priority of the communications types

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 when accessing the HTML pages in the Web browser.

Disabling the Web server function

As default, the CP is enabled for communication via HTTP. If you do not want to use the CP

for IP communication with HTTP, you will need to deactivate port 80 of the CP in the STEP 7

configuration:

Select the option "Activate Web server" under "IP access protection" in the properties dialog

of the CP.

Port 80 is enabled as default.

Web browser

To access the HTML pages on the CP, you require a Web browser. The following Web

browsers are suitable for communication with the CP (other browsers also possible):

● Internet Explorer (recommended version: as of 6.0)

● Opera (recommended version: as of 9.2)

● Firefox (recommended version: as of 2.0)

You will find these Web browsers, information and addons on the Internet.
