l编程指令:指令是PLC被告知要做什么,以及怎样去做的代码或符号。从本质上讲,指令只是一些二进制代码,这点PLC与普通的计算机是完全相同的。同时PLC也有编译系统,它可以把一些文字符号或图形符号编译成机器码,所以用户看到的PLC指令一般不是机器码而是文字代码,或图形符号。常用的助记符语句用英文文字(可用多国文字)的缩写及数字代表各相应指令。常用的图形符号即梯形图,它类似于电气原理图是符号,易为电气工作人员所接受。
l指令系统:一个PLC所具有的指令的全体称为该PLC的指令系统。它包含着指令的多少,各指令都能干什么事,代表着PLC的功能和性能。一般讲,功能强、性能好的PLC,其指令系统必然丰富,所能干的事也就多。我们在编程之前必须弄清PLC的指令系统
l程序:PLC指令的有序集合,PLC运行它,可进行相应的工作,当然,这里的程序是指PLC的用户程序。用户程序一般由用户设计,PLC的厂家或代销商不提供。用语句表达的程序不大直观,可读性差,特别是较复杂的程序,更难读,所以多数程序用梯形图表达。
