PLC控制系统是在传统的顺序控制器的基础上引入了微电子技术、计算机技术、自动控制技术和通讯技术而形成的一代新型工业控制装置，目的是用来取代继电器、执行逻辑、记时、计数等顺序控制功能，建立柔性的程控系统。具有通用性强、使用方便、适应面广、可靠性高、抗干扰能力强、编程简单等特点。

PLC内部工作方式一般是采用循环扫描工作方式，在一些大、中型的PLC中增加了中断工作方式。当用户将用户程序调试完成后，通过编程器将其程序写入PLC存储器中，同时将现场的输入信号和被控制的执行元件相应的连接在输入模块的输入端和输出模块的输出端，接着将PLC工作方式选择为运行工作方式，后面的工作就由PLC根据用户程序去完成，右图是PLC执行过程框图。PLC在工作过程中，主要完成六个模块的处理。Cutler Hammer EATON 9560H1565-69 model  6-331-25
