 3．PLC大力开发智能模块，加强联网通信能力

 为满足各种自动化控制系统的要求，近年来不断开发出许多功能模块，如高速计数模块、温度控制模块、远程I/O模块、通信和人机接口模块等。这些带CPU和存储器的智能I/O模块，既扩展了PLC功能，又使用灵活方便，扩大了PLC应用范围。

加强PLC联网通信的能力，是PLC技术进步的潮流。PLC的联网通信有两类：一类是PLC之间联网通信，各PLC生产厂家都有自己的专有联网手段；另一类是PLC与计算机之间的联网通信，一般PLC都有专用通信模块与计算机通信。为了加强联网通信能力，PLC生产厂家之间也在协商制订通用的通信标准，以构成更大的网络系统，PLC已成为集散控制系统（DCS）不可缺少的重要组成部分。
