1.***处理单元(CPU)
CPU作为整个PLC的核心,起着总指挥的作用。CPU一般由控制电路、运算器和寄存器组成。这些电路通常都被封装在一个集成电路的芯片上。CPU通过地址总线、数据总线、控制总线与存储单元、输入输出接口电路连接。CPU的功能有以下一些:从存储器中读取指令,执行指令,取下一条指令,处理中断。
2.存储器(RAM、ROM)
存储器主要用于存放系统程序、用户程序及工作数据。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;存放工作数据的存储器称为数据存储器。常用的存储器有RAM、EPROM和EEPROM。RAM是一种可进行读写操作的随机存储器存放用户程序,生成用户数据区,存放在RAM中的用户程序可方便地修改。RAM存储器是一种高密度、低功耗、价格便宜的半导体存储器,可用锂电池做备用电源。掉电时,可有效地保持存储的信息。EPROM、EEPROM都是只读存储器。用这些类型存储器固化系统管理程序和应用程序。
