PLC的三种编程语言的特点介绍 
1．梯形图编程语言
梯形图沿袭了继电器控制电路的形式，它是在电器控制系统中常用的继电器、接触器逻辑控制基础上简化了符号演变来的，形象、直观、实用。
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，zui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。

2．语句表编程语言
指令语句表示一种与计算机汇编语言相类似的助记符编程方式，但比汇编语言易懂易学。一条指令语句是由步序、指令语和作用器件编号三部分组成。
3．控制系统流程图编程图
控制系统流程图是一种较新的编程方法。它是用像控制系统流程图一样的功能图表达一个控制过程，目前电工协会(IEC)正在实施发展这种新式的编程标准。
