PLC梯形圖經(jīng)驗(yàn)設(shè)計(jì)法的要點(diǎn)
①PLC的編程,從梯形圖來看,其根本點(diǎn)是找出系統(tǒng)中符合控制要求的各個(gè)輸出的工作條件,這些條件又總是用編程元件按一定的邏輯關(guān)系進(jìn)行組合來實(shí)現(xiàn)的。
②梯形圖的基本模式為啟—保—停電路。每個(gè)啟—保—停電路一般只針對(duì)一個(gè)輸出,這個(gè)輸出可以是系統(tǒng)的實(shí)際輸出,也可以是中間變量。
③梯形圖編程中有一些約定俗成的基本環(huán)節(jié),它們都有一定的功能,可以像擺積木一樣在許多地方應(yīng)用。
