可编程自动化控制器（PAC）作为新一代的工业控制器，代表着可编程自动化控制发展的未来。在可以预见的几年内，对标准性、开放性、可互操作性、可移植性的要求将是用户至为关心的自动化产品的重要特征，作为融汇了PC和PLC优点的PAC系统必将逐步取代PLC系统成为控制系统的主流产品，在工业自动化控制中的应用将会越来越广泛。
可编程控制器技术主要是应用于自动化控制工程中，如何综合地运用前面学过知识点，根据实际工程要求合理组合成控制系统，在此介绍组成可编程控制器控制系统的一般方法。
编程指令：指令是PLC被告知要做什么，以及怎样去做的代码或符号。从本质上讲，指令只是一些二进制代码，这点PLC与普通的计算机是完全相同的。同时PLC也有编译系统，它可以把一些文字符号或图形符号编译成机器码，所以用户看到的PLC指令一般不是机器码而是文字代码，或图形符号。常用的助记符语句用英文文字（可用多国文字）的缩写及数字代表各相应指令。常用的图形符号即梯形图，它类似于电气原理图是符号，易为电气工作人员所接受。
目前，世界上有200多个厂家生产可编程序控制器产品，比较著名的厂家有德国的西门子，美国的Rockwell(AB)、通用(GE),日本的三菱、欧姆龙，法国的施耐德等。
根据工作功能图表或状态流程图等设计出梯形图即编程。这一步是整个应用系统设计的核心工作，也是比较困难的一步，要设计好梯形图，首先要十分熟悉控制要求，同时还要有一定的电气设计的实践经验
