基本结构
PLC实质是一种专用于工业控制的计算机,其硬件结构基本上与微型计算机相同,基本构成为:
a、电源
PLC的电源在整个系统中起着十分重要的作用。如果没有一个良好的、可靠的电源系统是无法正常工作的,因此PLC的制造商对电源的设计和制造也十分重视。
一般交流电压波动在+10%(+15%)范围内,可以不采取其它措施而将PLC直接连接到交流电网上去
b. 中央处理单元(CPU)
中央处理单元(CPU)是PLC的控制中枢。它按照PLC系统程序赋予的功能接收并存储从编程器键入的用户程序和数据;检查电源、存储器、I/O以及警戒定时器的状态,
并能诊断用户程序中的语法错误。当PLC投入运行时,首先它以扫描的方式接收现场各输入装置的状态和数据,并分别存入I/O映象区,
然后从用户程序存储器中逐条读取用户程序,经过命令解释后按指令的规定执行逻辑或算数运算的结果送入I/O映象区或数据寄存器内。
等所有的用户程序执行完毕之后,后将I/O映象区的各输出状态或输出寄存器内的数据传送到相应的输出装置,如此循环运行,直到停止运行。
为了进一步提高PLC的可靠性,近年来对大型PLC还采用双CPU构成冗余系统,或采用三CPU的表决式系统。这样,即使某个CPU出现故障,整个系统仍能正常运行。
c、存储器
存放系统软件的存储器称为系统程序存储器。
存放应用软件的存储器称为用户程序存储器。
d、输入输出接口电路
1、现场输入接口电路由光耦合电路和微机的输入接口电路,作用是PLC与现场控制的接口界面的输入通道。
2、现场输出接口电路由输出数据寄存器、选通电路和中断请求电路集成,作用PLC通过现场输出接口电路向现场的执行部件输出相应的控制信号。
e、功能模块
如计数、定位等功能模块
f、通信模块
如以太网、RS485、Profibus-DP通讯模块等




工作原理编辑
一. 扫描技术
当PLC投入运行后,其工作过程一般分为三个阶段,即输入采样、用户程序执行和输出刷新三个阶段。完成上述三个阶段称作一个扫描周期。
在整个运行期间,PLC的CPU以一定的扫描速度重复执行上述三个阶段。
(一) 输入采样阶段 在输入采样阶段,PLC以扫描方式依次地读入所有输入状态和数据,并将它们存入I/O映象区中的相应得单元内。
输入采样结束后,转入用户程序执行和输出刷新阶段。在这两个阶段中,即使输入状态和数据发生变化,I/O映象区中的相应单元的状态和数据也不会改变。
因此,如果输入是脉冲信号,则该脉冲信号的宽度必须大于一个扫描周期,才能保证在任何情况下,该输入均能被读入。




可编程控制器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(I)和输出(O)接口,控制各种类型的机械设备或生产过程


可编程逻辑控制器(PLC)的定义  可编程逻辑控制器简称PLC(英文全称:Programmable Logic Controller)。随着科学技术的发展,为适应多品种,小批量生产的需求而产生发展起来的一种新型的工业控制装置。


1.现场输入接口电路由光耦合电路和微机的输入接口电路,作用是PLC与现场控制的接口界面的输入通道。


2.现场输出接口电路由输出数据寄存器  选通电路和中断请求电路集成,作用PLC通过现场输出接口电路向现场的执行部件输出相应的控制信号。


常用的I/O分类如下:


开关量:按电压水平分,有22-VAC  11-VAC  24VDC,按隔离方式分,有继电器隔离和晶体管隔离。


模拟量:按信号类型分,有电流型(4-2-mA,--2-mA)  电压型(--1-V,--5V,-1--1-V)等,按精度分,有12bit,14bit,16bit等。除了上述通用IO外,还有特殊IO模块,如热电阻  热电偶  脉冲等模块。


按I/O点数确定模块规格及数量,I/O模块可多可少,但其大数受CPU所能管理的基本配置的能力,即受大的底板或机架槽数限制。
