2　PLC的构成 

　　从结构上分，PLC分为固定式和组合式（模块式）两种。固定式PLC包括CPU板、I/O板、显示面板、内存块、电源等，这些元素组合成一个不可拆卸的整体。模块式PLC包括CPU模块、I/O模块、内存、电源模块、底板或机架，这些模块可以按照规则组合配置。 

3　CPU的构成 

　　CPU是PLC的核心，起神经中枢的作用，每套PLC至少有一个CPU，它按PLC的系统程序赋予的功能接收并存贮用户程序和数据，用扫描的方式采集由现场输入装置送来的状态或数据，并存入规定的寄存器中，同时，诊断电源和PLC内部电路的工作状态和编程过程中的语法错误等。进入运行后，从用户程序存贮器中逐条读取指令，经分析后再按指令规定的任务产生相应的控制信号，去指挥有关的控制电路。 

　　CPU主要由运算器、控制器、寄存器及实现它们之间联系的数据、控制及状态总线构成，CPU单元还包括外围芯片、总线接口及有关电路。内存主要用于存储程序及数据，是PLC不可缺少的组成单元。 

　　在使用者看来，不必要详细分析CPU的内部电路，但对各部分的工作机制还是应有足够的理解。CPU的控制器控制CPU工作，由它读取指令、解释指令及执行指令。但工作节奏由震荡信号控制。运算器用于进行数字或逻辑运算，在控制器指挥下工作。寄存器参与运算，并存储运算的中间结果，它也是在控制器指挥下工作。 

　　CPU速度和内存容量是PLC的重要参数，它们决定着PLC的工作速度，IO数量及软件容量等，因此限制着控制规模。 

4　I/O模块 

　　PLC与电气回路的接口，是通过输入输出部分（I/O）完成的。I/O模块集成了PLC的I/O电路，其输入暂存器反映输入信号状态，输出点反映输出锁存器状态。输入模块将电信号变换成数字信号进入PLC系统，输出模块相反。I/O分为开关量输入（DI），开关量输出（DO），模拟量输入（AI），模拟量输出（AO）等模块。 

　　常用的I/O分类如下： 

　　开关量：按电压水平分，有220VAC、110VAC、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（4-20mA,0-20mA）、电压型（0-10V,0-5V,-10-10V）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。
