With an increasing demand for a natural, intuitive man-machine interaction in automated industry, the graphical programming with PLC is attracting many applications nowadays. Today, the requirement for wireless communication environments in industry is becoming a crucial issue in the industrial process. In this paper, a PCbased virtual instrument (VI) to carry out a remote monitoring and control for a precise riveting system via the Wireless Internet has been developed. A good performance was verified by the real-time implementation results, and an illustrative demonstration was presented as well.
