施耐德140CPU11303 输入模块
整体式
整体式结构的可编程序控制装置把电源、CPU、存储器、I/O系统都集成
plc结构plc结构
在一个单元内，该单元叫做作基本单元。一个基本单元就是一台完整的PLC。
控制点数很难满足需要时，可再接扩展单元。整体式结构的特点是十分紧凑、体积小、低成本、安装方便。
结合式
结合式结构的可编程序控制装置是把PLC系统的各个结合而成部分按功能分成
plc结合plc结合
若干个模块，如CPU模块、输入模块、输出模块、电源模块等等。其中各模块功能相对单一，模块的类别却日趋丰富。例如，一些可编程序控制装置，除了－些基本的I/O模块外，还有一些特殊功能模块，像温度检测模块、位置检测模块、PID控制模块、通讯模块等等。结合式结构的PLC特点是CPU、输入、输出都是独立的模块。模块尺寸统一、安装整齐、I/O点选型自由、调试安装、扩展、易于维护。
叠装式
叠装式结构集整体式结构的紧凑、体积小、安装方便和结合式结构的I/O点搭配灵话、安装整齐的特点于一体。它也是由各个单元的结合形成。它的特点是CPU自成独立的基本单元（由CPU和的I/O点结合而成），其它I/O模块为扩展单元。在安装过程中不用基板，仅用电缆进行单元间的连接，各个单元可以一个个地叠装。使系统达到布置灵活、体积小巧。
