Web interface to an input/output device

摘要

A control system allows a user to access an input/output device over a communication network using a web browser. The system includes an Internet web site between the network and the input/output module. The web site runs from an Ethernet board coupled directly to the input/output module back plane and includes a HTTP protocol interpreter, an input/output module, a TCP/IP stack, and an Ethernet board kernel. The web site provides access to the input/output module by a user at a remote location through the Internet. The web site translates the 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.
