Motion Automation Control System of Ship Assembly Robot Based on PLC

OPC has been widely applied to coal mine automation control system as an industry standard of communication between the field control substation and PC in the control system. In this paper, through the analysis and design for the transport system of coal mine belt conveyor, communication between the PC and S7-300 PLC is realized by using OPC technology. This paper gives the configuration scheme of OPC Server and develops the OPC Client program. The actual operation shows that the system is stable, reliable of communication and high of data real-time.
