Siemens SINAMICS S120 Commissioning Manual page 159

Deactivating the web server
When your converter is supplied, the web server is activated as default setting. When
required, you can deactivate the web server as follows:
1. In the configuration dialog, deactivate the "Activate" option.
2. Then save the project to accept the settings.
Restricting web server access to just secure connections
Using the default configuration of the web server, you can access the SINAMICS S120
converter via an HTTP connection or via an encrypted HTTPS connection. Using the
configuration, access can be restricted so that only a secure HTTPS connection is possible.
To prevent hacking attacks and data manipulation, we recommend that you restrict access to
just the secure HTTPS connection.
NOTICE
Using non-encrypted connections (HTTP)
When using the HTTP protocol, the login data is also sent unencrypted. Using the HTTP
protocol facilitates, among other things, hacking attacks and stolen passwords – and can
result in data manipulation by unauthorized persons.
• Limit access to secure HTTPS connections so that all data is transferred encrypted.
The configuration option provided to limit connections to just HTTPS can only be changed
when the web server is active:
● In the Startdrive configuration dialog
● In the web server prior to commissioning for the first time
● Using parameter p8986
Note
Access to the web server via PROFINET interface X150
In the parameter view, you can configure HTTP or HTTPS access to the web server via a
PROFINET interface using parameters p8986.1, p8984 and p8985. To do this, you must
activate access to the web server with p8986.0 = 1 or via the screen form "Web Server".
Procedure:
1. In the configuration dialog, activate option "Only permit access via https".
