The communication mode of PC and PLC based on Web and Ethernet is made of PC, PLC and Ethernet module .In the view of the limitation of the scope of PLC control, the poor integration of control system, the bad unified control of real-time, and the communication mode of PC and PLC based on Web and Ethernet is proposed.A hardware system which included LabVIEW web server, PLC, Ethernet module, TP-Link, and stepper motors is designed.In addition, the software system of the Ethernet communication between PC and PLC based on TCP/IP Modbus protocol is developed by using the LabVIEW graphics software.Through the Web server of LabVIEW, the VI control panel is released to the Internet aiming at achieving the remote control.The feasibility of this communication mode is verified by the experiment of the speed feedback of the encoder.
