PLC与单片机的差别是：
1、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。
2、而单片机可以构成各种各样的应用系统，使用范围更广。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。
3、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。
4、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。
从本质上说，PLC其实就是一套已经做好的单片机(单片机范围很广的)系统。
但PLC也有其特点：PLC广泛使用梯形图代替计算机语言，对编程有一定的优势。你可以把梯形图理解成是与汇编等计算器语言一样，是一种编程语言，只是使用范围不同!而且通常做法是由PLC软件把你的梯形图转换成C或汇编语言(由PLC所使用的CPU决定)，然后利用汇编或C编译系统编译成机器码!PLC运行的只是机器码而已。梯形图只是让使用者更加容易使用而已。
