Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
75 words
Coupler for a programmable logic controller connecting to an Ethernet network (BE) under the TCP/IP protocol to communicate with various equipment, characterized by the fact that it uses two disk partitions in a flash memory, one acting as a disk for the real time operating system, the other acting as a user disk, these two disks being accessed through the FTP protocol on TCP/IP, and the user disk space being managed by an HTTP server.
Claim 2
Dependent Claim
75 words
Coupler for a programmable logic controller connecting to an Ethernet network (BE) under the TCP/IP protocol to communicate with various equipment, characterized by the fact that it uses two disk partitions in a flash memory, one acting as a disk for the real time operating system, the other acting as a user disk, these two disks being accessed through the FTP protocol on TCP/IP, and the user disk space being managed by an HTTP server.
Claim 3
Dependent Claim
68 words
Coupler according to claim 1 , characterized by the fact that remote access to the system space is authorized with FTP under a system account so that the system can be updated remotely without any physical action on the coupler while keeping the said coupler in normal operation, and the user disk space can be remotely accessed with FTP or HTTP under an account called the user account.
Claim 4
Dependent Claim
31 words
Coupler according to claim 1 , characterized by the fact that the system space contains executable files, a system initialization file, a system diagnostic file and a test file for production.
Claim 5
Dependent Claim
31 words
Coupler according to claim 2 , characterized by the fact that the system space contains executable files, a system initialization file, a system diagnostic file and a test file for production.
