1.图形式指令结构:程序由图形方式表达,指令由不同的图形符号组成,易于理解和记忆。系统的软件开发者已把工业控制中所需的独立运算功能编制成象征性图形,用户根据自己的需要把这些图形进行组合,并填入适当的参数。在逻辑运算部分,几乎所有的厂家都采用类似于继电器控制电路的梯形图,很容易接受。如西门子公司还采用控制系统流程图来表示,它沿用二进制逻辑元件图形符号来表达控制关系,很直观易懂。较复杂的算术运算、定时计数等,一般也参照梯形图或逻辑元件图给予表示,虽然象征性不如逻辑运算部分,也受用户欢迎  

  2.明确的变量常数:图形符相当于操作码,规定了运算功能,操作数由用户填人,如:K400T120等。PLC中的变量和常数以及其取值范围有  

明确规定,由产品型号决定,可查阅产品目录手册。  

  3.简化的程序结构:PLC的程序结构通常很简单,典型的为块式结构,不同块完成不同的功能,使程序的调试者对整个程序的控制功能和控制顺序有清晰的概念。
