dcs和plc的设计原理区别较大，plc是由继电器控制原理发展起来的，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，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zui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。
