盡管梯形圖與繼電器電路圖在結(jié)構(gòu)形式、元件符號(hào)及邏輯控制功能等方面相類似，但它們又有許多不同之處，梯形圖具有自己的編程規(guī)則。

1）每一邏輯行總是起于左母線，然后是觸點(diǎn)的連接，zui后終止于線圈或右母線（右母線可以不畫出）。注意：左母線與線圈之間一定要有觸點(diǎn)，而線圈與右母線之間則不能有任何觸點(diǎn)。

2）梯形圖中的觸點(diǎn)可以任意串聯(lián)或并聯(lián)，但繼電器線圈只能并聯(lián)而不能串聯(lián)。

3）觸點(diǎn)的使用次數(shù)不受限制。

4）一般情況下，在梯形圖中同一線圈只能出現(xiàn)一次。如果在程序中，同一線圈使用了兩次或多次，稱為“雙線圈輸出”。對(duì)于“雙線圈輸出”，有些PLC將其視為語(yǔ)法錯(cuò)誤，不允許；有些PLC則將前面的輸出視為無(wú)效，只有zui后一次輸出有效；而有些PLC，在含有跳轉(zhuǎn)指令或步進(jìn)指令的梯形圖中允許雙線圈輸出。
