梯形图的设计应注意以下三点：

（一）梯形图按从左到右、从上到下的顺序排列。每一逻辑行起始于左母线，然后是触点的串、并联接，后是线圈与右母线相联。

（二）梯形图中每个梯级流过的不是物理电流，而是“概念电流”，从左流向右，其两端没有电源。这个“概念电流”只是形象地描述用户程序执行中应满足线圈接通的条件。

（三）输入继电器用于接收外部输入信号，而不能由PLC内部其它继电器的触点来驱动。因此，梯形图中只出现输入继电器的触点，而不出现其线圈。输出继电器输出程序执行结果给外部输出设备，当梯形图中的输出继电器线圈得电时，就有信号输出，但不是直接驱动输出设备，而要通过输出接口的继电器、晶体管或晶闸管才能实现。输出继电器的触点可供内部编程使用。
