PLC与单片机有哪些区别?
PLC是应用单片机构成的比较成熟的控制系统，是已经调试成熟稳定的单片机应用系统的产品，有较强的通用性。
单片机可以构成各种各样的应用系统，使用范围更广，但单就“单片机”而言，它只是一种集成电路，还必须与其它元器件及软件构成系统才能应用。
从工程的使用来看，对单项工程或重复数极少的项目，采用PLC快捷方便，*率高，可靠性好，但成本较高。
对于量大的配套项目，采用单片机系统具有成本低、效益高的优点，但这要有相当的研发力量和行业经验才能使系统稳定。
结:从本质上说，PLC其实就是一套已经做好的单片机(单片机范围很广泛)系统。
单片机可以取代PLC吗?
有人说这是个伪问题，单片机是元器件，PLC是由元器件以及庞大的软件构成的系统，两者在这一方面没有可比性 —— 大多PLC的控制芯片实际上就是单片机，也就是说可以将PLC看成是单片机的二次开发。单论工业防护等级，单片机的稳定性和可靠性能根本比不了PLC这种IP67类的产品( IP为标记字母，标记数字表示接触保护和外来物保护等级，第二标记数字表示防水保护等级)。而且就PLC这种能应对工业恶劣环境的产品还开发出一套冗余系统。
