plc的核心部件是cpu和存储器：

（1）中央处理单元（cpu）

中央处理单元（cpu）是plc 的控制中枢。它按照plc系统程序赋予的功能，接受并存储从编程器键入的用户程序和数据，检查电源、存储器、i/o以及警戒定时器的状态，并能检查用户程序的语法错误。当plc投入运行时，首先它以扫描的方式接受现场各输入装置的状态和数据，并分别存入i/o映象区, 然后从用户程序存储器中逐条读取用户程序，经过命令解释后按指令的规定执行逻辑或算术运算等任务。并将逻辑或算术运算等结果送入i/o映象区或数据寄存器内。等所有的用户程序执行完毕以后，后将i/o映象区的各输出状态或输出寄存器内的数据传送到相应的输出装置，如此循环运行，直到停止运行为止。

（2）存储器

与微型计算机一样，除了硬件以外，还必须有软件。才能构成一台完整的plc。plc的软件分为两部分: 系统软件和应用软件。存放系统软件的存储器称为系统程序存储器。

plc存储空间的分配：虽然大、中、小型 plc的cpu的大可寻址存储空间各不相同，但是根据plc的工作原理， 其存储空间一般包括以下三个区域：系统程序存储区，系统ram存储区（包括i/o映象区和系统软设备等）和用户程序存储区。diecastbox with shrouded start switch & emergency stopswitch
