1.可编程控制器原理--简介
可编程逻辑控制器,其英文全称为Programmable Logic Controller,简称PLC,它是一种数字运算操作的电子系统,专门在工业环境下应用而设计。它采用可以编制程序的存储器,用来在执行存储逻辑运算和顺序控制、定时、计数和算术运算等操作的指令,并通过数字或模拟的输入和输出接口,控制各种类型的机械设备或生产过程。
2.可编程控制器原理--构成
可编程控制器(PLC)是一种专门为在工业环境下应用而设计的数字运算操作的电子装置,它主要是由以下几部分构成的:
中央处理单元(CPU):它是PLC的控制中枢,是PLC的核心起神经中枢的作用,每套PLC至少有一个CPU。
存储器:它是存放系统软件的存储器;用户程序存储器是存放PLC用户程序应用;数据存储器用来存储PLC程序执行时的中间状态与信息,它相当于PC的内存。
输入输出接口(I/O模块):它主要是完成PLC与电气回路的接口。I/O模块集成了PLC的I/O电路,其输入暂存器反映输入信号状态,输出点反映输出锁存器状态。
通信接口:它的主要作用是实现PLC与外部设备之间的数据交换(通信)。
电源:PLC的电源为PLC电路提供工作电源,在整个系统中起着十分重要的作用。
3.可编程控制器原理
可编程控制器(PLC)是采取顺序扫描,不断循环,的方式进行工作的,即在PLC运行时,PLC根据用户按控制要求编好并存放于用户程序存储器中的程序,按指令步序号或地址号作周期性循环扫描,如无跳转指令,则从**条指令开始逐条顺序执行用户程序,直至程序结束,然后重新返回**条指令,开始下一轮扫描,在每一次扫描过程中,还要完成对输入信号的采样和对输出状态的刷新等工作。
