PLC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*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。鸿飞达-李工
