PLC交通燈控制電路設(shè)計(jì)

1、 實(shí)訓(xùn)六 交通燈控制一、實(shí)訓(xùn)目的（1）通過使用邏輯指令編程、狀態(tài)轉(zhuǎn)移圖編程和功能指令編程，訓(xùn)練編程的思想和方法； （2）熟悉PLC的技術(shù)應(yīng)用，提高應(yīng)用PLC的能力。二、控制要求交通燈的控制要求如表1所示。表1東西向綠燈Y0綠燈Y0閃爍黃燈Y1紅燈Y220SON 0.5S OFF 0.5S 2次2S南北向紅燈Y3綠燈Y4綠燈Y4閃爍黃燈Y530SON 0.5S OFF 0.5S 2次2S三、實(shí)訓(xùn)指導(dǎo)1根據(jù)控制要求分配 I/O元件（表2） 表2功能說明輸入元件（I）功能說明輸出元件（O）程序啟動(dòng)按鈕X000東西向綠燈Y000黃燈Y001紅燈Y002程序停止按鈕X001南北向綠燈Y003黃燈Y004
