編程規(guī)則與典型程序塊
    利用梯形圖編程與采用繼電器控制電路有些相似，因此，很多人習(xí)慣采用梯形圖編程。梯形圖編程有些基本要求和規(guī)則，也有一些規(guī)律可循。
    2.1梯形圖設(shè)計(jì)的基本原則
    PLC編程應(yīng)注意以下基本原則。
    （1）外部輸入/輸出繼電器、內(nèi)部繼電器、定時(shí)器、計(jì)數(shù)器等軟元件的觸點(diǎn)可重復(fù)使用，沒有必要特意采用復(fù)雜程序結(jié)構(gòu)來減少觸點(diǎn)的使用次數(shù)。
    （2）梯形圖每一行都是從左母線開始，線圈接在zui右邊。在繼電器控制原理圖中，繼電器的觸點(diǎn)可以放在線圈的右邊，但在梯形圖中觸點(diǎn)不允許放在線圈的右邊。如圖6-10所示。

（3）線圈不能直接與左母線相連，也就是說線圈輸出作為邏輯結(jié)果必須有條件。必要時(shí)可以使用一個(gè)內(nèi)部繼電器的動斷觸點(diǎn)或內(nèi)部特殊繼電器來實(shí)現(xiàn)。參見圖6-11所示。

（4）同一編號的線圈在一個(gè)程序中使用兩次以上稱為雙線圈輸出。雙線圈輸出容易引起誤操作，這時(shí)前面的輸出無效，只有zui后的輸出才有效。但該輸出線圈對應(yīng)觸點(diǎn)的動作，要根據(jù)該邏輯運(yùn)算之前的輸出狀態(tài)來判斷。如圖6-12所示，由于M1雙線圈輸出，所以，M1輸出隨zui后一個(gè)M1輸出變化，Y1隨*個(gè)M1線圈變化，而Y2隨第二個(gè)M1輸出變化。所以，一般情況下，應(yīng)盡可能避免雙線圈輸出。

    （5）梯形圖程序必須符合順序執(zhí)行的原則，即從左到右，從上到下執(zhí)行，如不符合順序執(zhí)行的電路不能直接編程，例如圖6-13所示電路不能直接編程。
    （6）梯形圖中串、并聯(lián)的觸點(diǎn)次數(shù)沒有限制，可以無限制的使用
