 梯形图是PLC控制系统中使用得多的图形编程语言，被称为PLC的一编程语言。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。PLC梯形图设计规则（或规范）如下：

(1)触点应画在水平线上，不能画在垂直分支上。应根据自左至右、自上而下的原则和对输出线圈的几种可能控制路径来画。

(2)不包含触点的分支应放在垂直方向，不可放在水平位置，以便于识别触点的组合和对输出线圈的控制路径。

(3)在有几个串联回路相并联时，应将触头多的那个串联回路放在梯形图的上面。在有几个并联回路相串联时，应将触点多的并联回路放在梯形图的左面。这种安排，所编制的程序简洁明了，语句较少。

(3)不能将触点画在线圈的右边，只能在触点的右边接线圈。
