PLC是專為工業(yè)控制而開發(fā)的裝置，其主要使用者是工廠廣大電氣技術(shù)人員，為了適應(yīng)他們的傳統(tǒng)習(xí)慣和掌握能力，通常PLC不采用微機的編程語言，而常常采用面向控制過程、面向問題的“自然語言”編程。電工委員會（IEC）1994年5月公布的IEC1131-3（可編程控制器語言標(biāo)準(zhǔn)）詳細(xì)地說明了句法、語義和下述5種編程語言：功能表圖（sequential   function chart）、梯形圖（Ladder diagram）、功能塊圖（Function black diagram）、指令表（Instruction list）、結(jié)構(gòu)文本（structured text）。梯形圖和功能塊圖為圖形語言，指令表和結(jié)構(gòu)文本為文字語言，功能表圖是一種結(jié)構(gòu)塊控制流程圖。

梯形圖是使用得zui多的圖形編程語言，被稱為PLC的*編程語言。梯形圖與電器控制系統(tǒng)的電路圖很相似，具有直觀易懂的優(yōu)點，很容易被工廠電氣人員掌握，特別適用于開關(guān)量邏輯控制。梯形圖常被稱為電路或程序，梯形圖的設(shè)計稱為編程。
