5.6 Web server
The web server provides information on a SINAMICS device via its web pages. The web server
accesses the device via an Internet browser. The information on the web pages is shown in
German or English. You can choose the language for the following information:
● Message texts
● Drive object statuses
● Parameter names
You can choose between a number of languages for displaying this information:
The most important functions of the web server are described below. The "User's area" display
area of the web server is described in detail in a separate document. You will find further
information on this in the section titled "User-defined web pages".
Note
Total memory size of user files
The total amount of data stored by the web server must not exceed the total memory size of
100 MB. The total memory size of the stored data influences the backup times. The larger the
data volume, the longer the backup takes.
Basic configuration
There are two options for the basic configuration of the web server:
● Via STARTER
● During first commissioning or via the web server itself
The web server is deactivated by default in the factory setting of the drive.
Data transfer
In addition to normal, unsecured HTTP transmission, the web server also supports secure
HTTPS transmission. With the input of the appropriate address, you can decide yourself
whether normal or secure transmission is used to access the data.
You can force secure transmission for security reasons by deactivating the HTTP port.
