1 引言

　　 可编程序控制器的英文为Programmable Controller，在二十世纪70-80年代一直简称为PC。由于到90年代，个人计算机发展起来，也简称为PC;加之可编程序的概念所涵盖的范围太大，所以美国AB公司将可编程序控制器定名为可编程序逻辑控制器(PLC-Programmable Logic Controller)，为了方便，仍简称PLC为可编程序控制器。有人把可编程序控制器组成的系统称为PCS可编程序控制系统，强调可编程序控制器生产厂商向人们提供的已是完整的系统了。

　　2 PLC的发展和市场情况

　　2.1 PLC的发展历史

　　 1968年美国GM(通用汽车)公司提出取代继电器控制装置的要求，第二年美国数字公司研制出了第1代可编程序控制器，满足了GM公司装配线的要求。随着集成电路技术和计算机技术的发展，现在已有第五代PLC产品了。
