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。
3．输入输出单元（I/O单元）
I/O单元实际上是PLC与被控对象间传递输入输出信号的接口部件。I/O单元有良好的电隔离和滤波作用。接到PLC输入接口的输入器件是各种开关、按钮、传感器等。PLC的各输出控制器件往往是电磁阀、接触器、继电器，而继电器有交流和直流型，高电压型和低电压型，电压型和电流型。
4．电源
PLC电源单元包括系统的电源及备用电池，电源单元的作用是把外部电源转换成内部工作电压。PLC内有一个稳压电源用于对PLC的CPU单元和I/O单元供电。
5．编程器
编程器是PLC的zui重要外围设备。利用编程器将用户程序送入PLC的存储器，还可以用编程器检查程序，修改程序，监视PLC的工作状态。除此以外，在个人计算机上添加适当的硬件接口和软件包，即可用个人计算机对PLC编程。利用微机作为编程器，可以直接编制并显示梯形图。
