Restricting Web server access to a secure connection
Using the default configuration of the Web server, you can access SINAMICS data via an
HTTP connection as well as via the secure HTTPS connection. Using the configuration,
access can be restricted so that only the secure HTTPS connection is possible. The
configuration option provided for this purpose can only be changed when the Web server is
active.
Note
Certificates for the secure https connection
You require security certificates for both SINAMICS and the Internet Browser to access the
Web server via an https connection. You must install these security certificates on your
computer.
Detailed information can be found in Section "Certificates for the secure data transfer
(Page 418)".
1. In the configuration dialog box, activate the "Only permit access via secure connection
(https)" checkbox.
2. If you do not want to assign passwords for read and write access (see Section "Assigning
a password (Page 393)"), click "OK".
The basic configuration of the Web server is then completed.
