| Abstract: | It is a new control method based on touching screen and PLC in the modern industrial control system,and their applications are more and more widely.Based on the Mitsubishi F940GOT-LWD-C touching screen and FX0S-30MR PLC,a four-way vying answer machine control system is proposed.This paper describes the working theory and characters of touching screen,and expatiates hardware and software designing scheme of the system,and implements the monitoring and controlling to the four-way vying answer machine.The software design includes graphic running system of touching screen and control program based on sequential function chart.The application indicates that the system has some advantages of running stably,high reliability and better practicability. |
