八、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，还未实现互操作性，IEC规定了多种现场总线标准，PLC各厂家均有采用。

    对于一个自动化工程(特别是中大规模控制系统)来讲，选择网络非常重要的。首先，网络是开放的，以方便不同设备的集成及未来系统规模的扩展；其次，针对不同网络层次的传输性能要求，选择网络的形式，这在较深入地了解该网络标准的协议、机制的前提下进行；再次综合考虑系统成本、设备兼容性、现场环境适用性等具体问题，确定不同层次所使用的网络标准。
