NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
You set the built-in EtherNet/IP port in the BOOTP settings to use the BOOTP client to obtain settings,
such as the built-in EtherNet/IP port IP address.
An FTP server is built into the built-in EtherNet/IP port so that files can be read from and written to the
SD Memory Card in the CPU Unit of the Controller from computers at other Ethernet nodes. This
makes it possible to exchange data files between a host computer and the Controller with the host com-
puter as the FTP client and the Controller as the FTP server.
