描述

PLC的基本组成可分为两大部分：硬件系统和软件系统。

硬件系统是指组成PLC的所有物理电子电路，其中主要有：中央处理器(CPU)、存储器、输入/输出(Input/Output)接口、通信接口、编程器和电源等部分，此外还有扩展设备和EPROM的读写板和打印机等选配的设备。为了维护、修理的方便，许多PLC采用模块结构。由中央处理器、存储器组成主控模块，输入单元组成输入模块，输出单元组成输出模块，三者通过专用总线构成主机，并由电源模块集中对其提供电能。

编程器可采用袖珍式编程器，也可采用安装有专门plc编程软件的通用计算机，通过编程口对PLC进行编程。

软件系统是指管理、控制、使用PLC，确保PLC正常工作的一整套程序。这些程序有的来自PLC生产厂家，也有的来自用户。一般称前者为系统程序，后者为用户程序。系统程序是指控制和完成PLC各种功能的程序，侧重于管理PLC的各种资源、控制和协调各硬件的正常动作及关系，以便充分发挥整个可编程控制器的使用效率，方便广大用户的直接使用。用户程序是指使用者根据生产工艺要求编写的控制程序，它侧重于应用，以及输入、输出之间的逻辑控制关系。

PLC等效电路中的继电器并不是实际的物理继电器，它实质上是存储器单元的一个“位”寄存器。“位”寄存器的状态为“1”时，相当于继电器接通；“位”寄存器的状态为“0”时，则相当于继电器断开。因此，称这些继电器为“软继电器”。

PLC是采用“顺序扫描，不断循环”的方式进行工作的，即在PLC运行时，CPU根据用户按控制要求事先编制好并保存于用户程序存储器中的程序，按指令步序号（或地址号）作周期性循环扫描，如无跳转指令，则从第一条指令开始逐条顺序执行用户程序，直至程序结束，然后重新返回第一条指令，开始下一轮新的扫描。在每次扫描过程中，还要完成对输入信号的采样和对输出状态的刷新等工作。
