PLC系统的其它设备

　　7.1 编程设备：编程器是PLC开发应用、监测运行、检查维护不可缺少的器件，用于编程、对系统作一些设定、监控PLC及PLC所控制的系统的工作状况，但它不直接参与现场控制运行。小编程器PLC一般有手持型编程器，目前一般由计算机（运行编程软件）充当编程器。也就是我们系统的上位机。

　　7.2　人机界面：最简单的人机界面是指示灯和按钮，目前液晶屏（或触摸屏）式的一体式操作员终端应用越来越广泛，由计算机（运行组态软件）充当人机界面非常普及。

8　PLC的通信联网

　　依靠先进的工业网络技术可以迅速有效地收集、传送生产和管理数据。因此，网络在自动化系统集成工程中的重要性越来越显著，甚至有人提出"网络就是控制器"的观点说法。

　　PLC具有通信联网的功能，它使PLC与PLC 之间、PLC与上位计算机以及其他智能设备之间能够交换信息，形成一个统一的整体，实现分散集中控制。多数PLC具有RS-232接口，还有一些内置有支持各自通信协议的接口。PLC的通信现在主要采用通过多点接口（MPI）的数据通讯、PROFIBUS 或工业以太网进行联网。
