PLC由哪几部分硬件组成？
PLC的硬件一般由主机、I/O扩展机及外部设备组成。
（1）主机包括:微处理器（MPU）。常用的微处理器有:Z80A、8085、M6800、M6809、8086、M68000。单片机有:8039、8031、M6801。
存储器:PLC的存储器用于存储程序和数据，一般采用ROM或EPROM。
I/O接口:I/O接口是主机与外部设备、I/O模块等的连接部件，用于扩弃PLC总线的驱动能力输入输出点数。
（2）电源:电压范围在160VAC-260VAC。
（3）输入/输出模块:用于调理输入输出信号，对输入信号进行滤波、隔离、电平转换等。包括直流开关量输入模块，交流开关量输入模块，直流开关量输出模块，交流开关量输出模块。
（4）功能模块:包括A/D模块和D/A模块，温度传感器模块，高速计数模块，PID模块，远程I/O模块，通讯模块。
（5）扩展口
（6）编程器
（7）其他外设:打印机，显示器。
