　　編程簡單，容易掌握

　　目前，大多數plc仍采用繼電控制形式的“梯形圖編程方式”。既繼承了傳統控制線路的清晰直觀，又考慮到大多數工廠企業(yè)電氣技術人員的讀圖習慣及編程水平，所以非常容易接受和掌握。梯形圖語言的編程元件的符號和表達方式與繼電器控制電路原理圖相當接近。通過閱讀plc的用戶手冊或短期培訓，電氣技術人員和技術工很快就能學會用梯形圖編制控制程序。同時還提供了功能圖、語句表等編程語言。

　　plc在執(zhí)行梯形圖程序時，用解釋程序將它翻譯成匯編語言然后執(zhí)行(plc內部增加了解釋程序)。與直接執(zhí)行匯編語言編寫的用戶程序相比，執(zhí)行梯形圖程序的時間要長一些，但對于大多數機電控制設備來說，是微不足道的，完全可以滿足控制要求。
