| Abstract: | In order to realize more complex traffic lights at the crossroads of the control requirements,the article uses the experience design method of Mitsubishi PLC technology.On the basis of I/O assigning,PLC ladder diagram,program is designed,and analyzes the situation as follows： the daytime automatically or manually and yellow light flashing at night as well as the four subroutine function of emergency light.After the simulation debugging with PLC,the actual control is exactly the same with requirements. |
