編程規則與典型程序塊
    利用梯形圖編程與采用繼電器控制電路有些相似，因此，很多人習慣采用梯形圖編程。梯形圖編程有些基本要求和規則，也有一些規律可循。
    2.1梯形圖設計的基本原則
    PLC編程應注意以下基本原則。
    （1）外部輸入/輸出繼電器、內部繼電器、定時器、計數器等軟元件的觸點可重復使用，沒有必要特意采用復雜程序結構來減少觸點的使用次數。
    （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，繼電器的觸點可以放在線圈的右邊，但在梯形圖中觸點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果必須有條件。必要時可以使用一個內部繼電器的動斷觸點或內部特殊繼電器來實現。參見圖6-11所示。

（4）同一編號的線圈在一個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。但該輸出線圈對應觸點的動作，要根據該邏輯運算之前的輸出狀態來判斷。如圖6-12所示，由于M1雙線圈輸出，所以，M1輸出隨zui后一個M1輸出變化，Y1隨*個M1線圈變化，而Y2隨第二個M1輸出變化。所以，一般情況下，應盡可能避免雙線圈輸出。

    （5）梯形圖程序必須符合順序執行的原則，即從左到右，從上到下執行，如不符合順序執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、并聯的觸點次數沒有限制，可以無限制的使用
