可编程控制器PLC系统程序、用户程序、编程语言

1、系统程序

系统程序是PLC赖以工作的基础，采用汇编语言编写，在PLC出厂时就已固化于ROM型系统程序存储器中。

系统程序分为系统监控程序和解释程序。

系统监控程序用于监视并控制PLC的工作，如诊断PLC系统工作是否正常，对PLC各模块的工作进行控制，与处设交换信息，根据用户的设定使PLC比处在编制用户程序状态或者处在运行用户程序状态等。

解释程序用于把用户程序解释成微处理器能够执行的程序。来自PLC之家。 

2、用户程序

用户程序又称为应用程序，是用户为完成某一特定   的控制任务而利用PLC的编程语言编制的程序。 来自PLC之家。 

用户程序通过编程器输入到PLC的用户程序存储器中。 

3、编程语言

可编程控制器是通过程序对系统进行控制的，所以各种机型的PLC都有自己的编程语言。www.PLC100.com

PLC的编程语言有多种，如梯形图、语句表、逻辑功能图、逻辑方程式等。下面介绍常用的梯形图和语句表编程语言。
