<p>PROBLEM TO BE SOLVED: To provide a control system which allows a user to access an input/ output device over a communication network using a web browser. SOLUTION: A web site provided between the communication network and an input/output module runs from an Ethernet board connected directly to the input/output module back plane, includes a HTTP protocol interpreter, an input/output module, a TCP/IP stack, and an Ethernet board kernel, provides access to the input/output module by a user at a remote location through the Internet, and translates industry standard Ethernet, TCP/IP and HTTP protocols used on the Internet into data recognizable to the input/output module. Using this interface, the user can input or retrieve all pertinent data regarding the operation of the input/output device.</p> |
