9 File Management and File Access with FTP
Available storage
For information on the total memory available in the file system, the currently
available memory in the flash area and in the RAM area of the file system and
other operational data, refer to the Web diagnostics of your Advanced CP (start
page/file system) and the manual of your Advanced CP /1/.
Files are protected by access rights
Chapter 10.2 explains the security mechanisms governing information exchange
using a Web browser. Section 3.4.9 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 to access files on the S7 station with FTP (see
Section 3.4.9 ).
Notice
Remember that using the "everybody" user name, access is possible without a
password, however this user name normally has no access rights.
File access with FTP tools
Depending on your requirements, you can use different methods and tools for FTP
access.
S Special FTP tools
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.
Notice
Please 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 "Options"
tab in the configuration dialog. In the default setting, they are not case−sensitive.
