摘要
PLC和单片机不管是内部结构、外围接口、程序设计、工作环境、控制优劣等方面都有异同。在自动控制领域PLC和单片机都有自己的一席之地，有的设备既可以用PLC也可用单片机，在具体设计中我们应该考虑PLC和单片机的优缺点进行选择。
There are similarities and differences between PLC and single -chip microcomputer （SCM） in inner structure, peripheral interface, program design, working environment, and control quality and so on. In the field of the automatic control both PLC and SCM have their own space, Some of the equipments can use both of them. In the specific design, we should consider the advantages and disadvantages of the PLC and SCM selection.
