(4) Perform file transfer (FTP) (Details are explained in Chapter 5)
The Ethernet module supports the server function of the TCP/IP standard
protocol, FTP (File Transfer Protocol). By using the FTP commands, files in a
CPU module can be read or written in file units.
This allows files in a CPU module to be managed with devices such as
computers. This also allows files to be transferred or a file list to be browsed as
needed.
