可編程控制器與一般的計算機相類似，在軟件方面有系統軟件和應用軟件之分，只是可編程控制器的系統軟件由可編程控制器生產廠家固化在 ROM 中，一般的用戶只能在應用軟件上進行操作，即通過編程軟件來編制用戶程序。編程軟件是由可編程控制器生產廠家提供的編程語言，至今為止還沒有一種能適合各種可編程控制器的通用的編程語言，但是各個可編程控制器發展過程有類似之處，可編程控制器的編程語言即編程工具都大體差不多，一般有如下五種表達方式。
( 一 ) 梯形圖（ Ladder Diagram ）
梯形圖是一種以圖形符號及圖形符號在圖中的相互關系表示控制關系的編程語言，它是從繼電器控制電路圖演變過來的。梯形圖將繼電器控制電路圖進行簡化，同時加進了許多功能強大、使用靈活的指令，將微機的特點結合進去，使編程更加容易，而實現的功能卻大大超過傳統繼電器控制電路圖，是目前*普通的一種可編程控制器編程語言。
梯形圖及符號的畫法應按一定規則，各廠家的符號和規則雖不盡相同，但基本上大同小異，如圖 1 所示。

a) 歐姆龍 b) 松下 c) 三菱
對于梯形圖的規則，總結有以下具有共性的幾點，如表 1 所示，以便讀者加深對可編程控制器變成的認識和學習。
