Abstract
A coupler for a programmable logic controller connecting to an Ethernet network under the TCP/IP protocol in order to communicate with various equipment. The coupler uses two disk partitions in a flash memory, one acting as a disk for the real time operating system and the other acting as a user disk. The two disks are accessed through the FTP protocol on TCP/IP, and the user disk space is managed by an HTTP server.
