PLC与CPU区别
PLC是Programmable Logic Controller的英文缩写，中译名：可编
程逻辑控制器。
简单理解的话，它和个人电脑上的CPU类似，都属于某一类系统上
进行数据采集处理的核心，但使用范围和作用与一般CPU不同，而且
PLC不像个人电脑上的CPU一样单单指一个CPU，准确说它是一种控制
系统，拥有自己的CPU，同时配置了各种功能面板和 I/O 口，可通过
I/O 采集模拟量、开关量等进行分析处理，同时拥有强大的可编程能
力，一般利用梯形图程序中提供的各种软继电器即可实现一些复杂的
逻辑控制，省去了传统的硬件式继电器复杂的接线和经济成本。
PLC较之个人电脑的CPU来说，其特点是拥有强大的数据采集能力和
对某一种自动控制过程的优秀处理能力，在工业上、制造业上，民用
比如电梯、自动洗衣机等的过程控制中有着广泛的应用。
