FTP Server

An FTP server is built into the EtherNet/IP Unit 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 computer as
the FTP client and the Controller as the FTP server.
