PLC交通灯控制电路设计

1、实训六交通灯控制、实训目的(1)通过使用逻辑指令编程、状态转移图编程和功能指令编程，训练编程的思想和方法;(2)熟悉plc的技术应用，提高应用plc的能力。：、控制要求交通灯的控制要求如表1所示。表1东西 向绿灯y0绿灯y0闪烁黄灯丫1红灯y220son 0.5soff0.5s 2 次2s南绿灯y4绿灯y4闪烁黄灯丫5北红灯y3向30son 0.5s off 0.5s 2 次2s三、实训指导1 根据控制要求分配i/o元件(表2)表2上二兑月x*东西向olyooyx)南北向3o y52 外部接线图(图1)3 使用逻辑指令编写程序(1)梯形图(图2)(2)指令表1 or m00 ld xooo3
