plc是由摸仿原继电器控制原理发展起来的，二十世纪七十年代的plc只有开关量逻辑控制，首先应用的是汽车制造行业。它以存储执行逻辑运算、顺序控制、定时、计数和运算等操作的指令；并通过数字输入和输出操作，来控制各类机械或生产过程。用户编制的控制程序表达了生产过程的工艺要求，并事先存入plc的用户程序存储器中。运行时按存储程序的内容逐条执行，以完成工艺流程要求的操作。plc的cpu内有指示程序步存储地址的程序计数器，在程序运行过程中，每执行一步该计数器自动加1，程序从起始步（步序号为零）起依次执行到终步（通常为end指令），然后再返回起始步循环运算。plc每完成一次循环操作所需的时间称为一个扫描周期。不同型号的plc，循环扫描周期在1微秒到几十微秒之间。plc用梯形图编程，在解算逻辑方面，表现出快速的优点，在微秒量级，解算1k逻辑程序不到1毫秒。它把所有的输入都当成开关量来处理，16位（也有32位的）为一个模拟量。大型plc使用另外一个cpu来完成模拟量的运算。把计算结果送给plc的控制器
