Files are protected by access rights
Section "User management" parameter group (Page 57) explains how access rights are
created when you configure the Advanced CP. The Advanced CP reacts to file access using
FTP according to the access rights; in other words you must authorize the access using a
password. The specified user must also have the right "Authorized to access files on the S7
station with FTP".
Note
User name "everybody"
Remember that using the "everybody" user name, access is possible without a password. As
default, the "everybody" user name, however, does not have any access rights.
Enable security
When you enable security on the CP, the "Authorized to access files on the S7 station with
FTP" access right is transformed to the corresponding multilevel settings of the CP. If
security is enabled, the CP supports individually selectable write / read permissions relating
to files on the CPU and CP.
File access with FTP tools
Depending on your requirements, you can use different methods and tools for FTP access:
● Special FTP tools
● MS DOS prompt
In the MS DOS prompt of Windows, you can establish an FTP connection and then execute
all the FTP commands supported by the Advanced CP.
The following example shows how you can find out which FTP commands are available
using the 'remote' command.

Special FTP tools are available that allow convenient use of FTP commands. Generally,
working with these tools is very similar to working with the Windows Explorer. This means
that you will use functions such as copying, moving or deleting files intuitively rather than
having to worry about the syntax of FTP commands. You will only need the MS DOS
prompt occasionally.
Note
Upper and lower case in file names
Note that with several CP types, the file names in the file system described here are
case-sensitive.
With the Advanced CPs as of CP 343-1 Advanced (GX30) and CP 443-1 Advanced
(GX20), file names can be made case-sensitive in the "Options" tab in the configuration
dialog. In the default setting, they are not case-sensitive.
