摘要:
A control system allows a user to access a programmable logic controller (PLC). system over a communication network such as an Internet network using a web browser. The system includes an Internet web interface between the network and the programmable logic controller. The Web interface serves Web pages from an Ethernet interface on a PLC and includes an HTTP protocol interpreter and a TCP/IP stack. The Web interface provides access to the PLC by a user at a remote location through the Internet. The interface translates the industry standard Ethernet, TCP/IP and HTTP protocols used on the Internet into data recognizable to the PLC. Using this interface, the user can retrieve all pertinent data regarding the operation of the programmable logic controller system.
