(b) Authentication by the FTP server
To access a password-protected file from external devices using the FTP server function, password
authentication is required for each file. Authentication is required whenever files are accessed.
Operation

Reading a file from a CPU module
Deleting a file in a CPU module
Reading a file from a CPU module
Changing the name of a file in a CPU module

To authenticate a password, use FTP commands for password authentication. Once the password is
authenticated, it is valid until the accessed external device logs out from the FTP server or the network line is
disconnected. (A password does not need to be authenticated every time the authentication target FTP
commands are executed.)
FTP command for password

The executability of FTP commands for password authentication differs depending on the access path to the
CPU module.
