You can create the file allocation table as follows and transfer it to the CP:
● With an entry in the parameter group "Properties > FTP configuration" described here
The file allocation table is then downloaded on the CP automatically along with the
project engineering data.
● By creating a file_db.txt file directly.
You will need to download the file allocation table created in this way to the CP using an
FTP command.
The file allocation table file_db.txt is stored in the file system of the Ethernet CP in the /config
folder.

according to the scheme shown in the following example:
