根据硬件结构的不同，可以将PLC分为整体式、模块式和混合式。

1.整体式PLC

整体式又叫做单元式或机箱式，它的体积小、价格低，对箱体式PLC，有一块CPU板、I/O板、显示面板、内存块、电源等，当然按CPU性能分成若干型号，并按I/O点数又有若干规格。对模块式PLC，有CPU模块、I/O模块、内存、电源模块、底板或机架。无任哪种结构类型的PLC，都属于总线式开放型结构，其I/O能力可按用户需要进行扩展与组合。

2.模块式PLC

大、中型PLC一般采用模块式结构，它由机架和模块组成，模块插在模块插座上，后者焊接在机架中的总线连接板上，有不同槽数的机架供用户选用，如果一个机架容纳不下选用的模块，可以增设一个或数个扩展机架，各机架之间用接口模块和电缆相连。

用户可以选用不同档次的CPU模块、品种繁多的I/O模块和特殊功能块，对硬件配置的选择余地较大，维修时更换模块也很方便。

3.CPU模块中的存储器

存储器分为系统程序存储器和用户程序存储器，系统程序相当于个人计算机中的操作系统，它使PLC具有基本的智能，能完成PLC设计者的规定的各种工作。系统程序由PLC的生厂家设计并固定化在ROM（只读存储器）中，用户不能读取。用户程序由用户设计，它使PLC能完成用户要球的特定功能，用户程序存储器的容量以字节（B）为单位。

（1）.随机存取存储器（RAM）

用户可以用编程装置读出RAM中的内容，也可以将用户程序写入RAM，因此RAM又叫读/写存储器。RAM的工作速度高、价格便宜、改写方便。

（2）.只读存储器（ROM）

ROM的内容只能读出，不能写入。

（3）.可以电檫出可编程的只读存储器（EEPROM）

S7-200用EEPROM来存储用户程序和长期保存的重要数据。

4.I/O模块

各I/O点的通/断状态用发光二极管（LED）显示，PLC与外部接线的连接一般用接线端子，某些模块使用可以拆卸的插座型端子板，不需断开端子板上的连接线，就可以迅速的更换模块。

输入模块：PLC通过输入模块来接收和采集输入信号，通过输出模块控制接触器、电磁阀、电磁铁、调速装置等执行器，PLC控制的另一类外部负载是指示灯、数字显示装置和报警装置等。输入电路中设有RC滤波电路，以防止由于输入触点抖动或外部干扰脉冲引起的错误输入信号。

输出模块：输出模块的率放大元件有大功率晶体管和场效应管（驱动直流负载）、双向可控硅（驱动交流负载）和小型继电器，继电器可以驱动交流负载或直流负载。输出电流的典型值为0.5—2A,负载电源由外部现场提供。
