梯形圖編程語言優(yōu)點是直觀、簡便，但要求用帶 CRT 屏幕顯示的圖形編程器才能輸入圖形符號。小型的編程器一般無法滿足，而是采用經(jīng)濟便攜的編程器（指令編程器）將程序輸入到可編程控制器中，這種編程方法使用指令語句（助記符語言），它類似于微機中的匯編語言。

語句是指令語句表編程語言的基本單元，每個控制功能有一個或多個語句組成的程序來執(zhí)行。每條語句規(guī)定可編程控制器中 CPU 如何動作的指令，它是由操作碼和操作數(shù)組成的。

操作碼用助記符表示要執(zhí)行的功能，操作數(shù)（參數(shù)）表明操作的地址或一個預(yù)先設(shè)定的值。歐姆龍、松下、三菱可編程控制器指令語句程序見表 2 。
