2、编程语言 

编程语言最为复杂，多种多样，看似相同，但不通用。最常用的可以划分为以下5类编程语言： 

（1）梯形图 

这是PLC厂家采用最多的编程语言，最初是由继电器控制图演变过来的，比较简单，对离散控制和互锁逻辑最为有用； 

（2）顺序功能图 

它提供了总的结构，并与状态定位处理或机器控制应用相互协调； 

（3）功能块图 

它提供了一个有效的开发环境，并且特别适用于过程控制应用； 

（4）结构化文本 

这是一种类似用于计算机的编程语言，它适用于对复杂算法及数据处理； 

（5）指令表 

它为优化编码性能提供了一个环境，与汇编语言非常相似。 

厂家提供的编程软件中一般包括一种或几种编程语言，如TE公司的XTEL编程软件可以使用梯形图（Ladder）、顺序功能图（Grafcet）、结构化文本（Literal）3 种编程语言；Siemens公司的Step7编程软件可以使用梯形图（Ladder）、指令表（STL）两种编程语言；Modicon公司的Modsoft编程软件只使用梯形图（984 梯形）一种编程语言，而另一个Concept编程软件可以使用5种编程语言，依次为梯形图（LD）、顺序功能图（SFC）、功能块图（FBD）、结构化文本（ST）、指令表（IL）。同一编程软件下的编程语言大多数可以互换，一般选择自己比较熟悉的编程语言。
