Features and Functions
Note
The availability of the data types CHAR, INT, DINT and REAL depends on the
firmware status of the S7-200 CPU being used.
Access protection
Calling the HTML pages stored in the file system of the CP 243.1 IT with a Web
browser is not subject to access protection. Such protection is not activated until
status or process variables are accessed from a Web browser or when an attempt
is made to send a test e-mail via the applicable HTML page.
The basic access authentication scheme described in RFC2617 is used as the au-
thentication routine for all password-protected HTML pages.
In this case, the user must authenticate himself with his user name and the related
password. Access to the HTTP server of the CP 243-1 IT is then granted or re-
fused depending on the access rights assigned to the user by user administration.
The HTTP server of the CP 243-1 IT can always be activated/deactivated with the
configuration.
HTML pages on the CP 243-1 IT
The file system of the CP 243-1 IT contains already prepared HTML pages in Eng-
lish which already supply status and diagnostic information via integration of the in-
cluded Java Applets. These HTML pages can be edited or further processed by the
user with an HTML editor such as Netscape Composer or a standard editor.
The following table lists the already predefined HTML pages which are included in
the file system of the CP 243-1 IT or which can be dynamically assembled by the
CP 243-1 IT as soon as a request from a Web browser is received. These HTML
pages have been optimized for monitor screen settings.
• Resolution: 1152 x 864
• Size of type: No type fonts
We recommend using the Internet Explorer 6.0 from Microsoft as your Web
browser.
