PLC是专为工业控制而开发的装置，其主要使用者是工厂广大电气技术人员，为了适应他们的传统习惯和掌握能力，通常PLC不采用微机的编程语言，而常常采用面向控制过程、面向问题的“自然语言”编程。电工委员会（IEC）1994年5月公布的IEC1131-3（可编程控制器语言标准）详细地说明了句法、语义和下述5种编程语言：功能表图（sequential   function chart）、梯形图（Ladder diagram）、功能块图（Function black diagram）、指令表（Instruction list）、结构文本（structured text）。梯形图和功能块图为图形语言，指令表和结构文本为文字语言，功能表图是一种结构块控制流程图。

梯形图是使用得zui多的图形编程语言，被称为PLC的*编程语言。梯形图与电器控制系统的电路图很相似，具有直观易懂的优点，很容易被工厂电气人员掌握，特别适用于开关量逻辑控制。梯形图常被称为电路或程序，梯形图的设计称为编程。
