Precise Riveting Systems Using Networked PLCs for Remote Monitoring and Control via the Internet

Today, Programmable Logic Controllers (PLCs) are widely used at the modern manufacturing automation. With an increasing demand for networking facility as well as a natural, intuitive man-machine interaction in automated industry, the graphical programming for multi-PLC control is gaining much attention nowadays. This paper develops a PC-based virtual instrument (VI) that can carry out a remote monitoring and control for up to eight-PLC-based precise riveting systems via the Internet. The real-time implementation shows its good performance and presents the illustrative demonstration.
