What should you watch out for when formatting the file system in the S7-300 and S7-400 Industrial Ethernet CPs?

The file system is for storing HTML files, applets and other user-specific files. The relevant files can be transferred to the modules by FTP (File Transfer Protocol).

The file system is supplied from the factory filled with default files. If you intend to delete the whole file system and start again in the output status, you can start formatting with the web browser (Internet Explorer, for example) with the following command as described in the device manual:

http://<IP address>/__FSys_Format
With this command you must observe uppercase and lowercase lettering.

The following prompt for input is displayed after the command has been executed.

Access to the FTP file system is protected by relevant rights and a password to prevent unauthorized manipulation of the FTP file system. For this reason, you must configure a user with appropriate rights in the STEP 7 configuration, who is permitted to access the FTP file system.

The user needs at least the following authorization:

  • Access with FTP to files in the S7 station.

Configuring a user
In the following we configure a user with administrator rights in the STEP 7 configuration. In the Hardware Configuration you open the Properties dialog of the Industrial Ethernet CP. Switch to the "Users" tab. Click the "Add..." button to create the new user.

Fig. 02: Properties IE CP dialog -> "Users" tab

In the following dialog you enter the user name. As administrator, the user receives authorization for all possible functions. Click the "Password" button.

Define the password for the user just added.

The user is activated automatically when the configuration is downloaded from STEP 7. Entering the relevant password provides unlimited access.

Install a new FTP file system
When you format the file system, it is then completely empty. This means that also factory-installed files are no longer available.

The file system for the IE IT and Advanced CPs listed in Table 1 is available for downloading. The file system for the other IE IT and Advanced CPs is available from Technical Support. After downloading, you must transfer the files to the Industrial Ethernet CP by FTP.
