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。
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**数受CPU所能管
理的基本配置的能力,即受**的底板或机架槽数限制。
电源模块
PLC电源用于为PLC各模块的集成电路提供工作电源。同时,有的还为输入电路
提供24V的工作电源。电源输入类型有:交流电源(220VAC或110VAC),直流
电源(常用的为24VDC)。
