摘要
WIA-FA是我国自主研制的面向工厂自动化的无线网络技术,实现工厂自动化设备之间高安全、高可靠的无线信息交互。本文重点介绍WIA-FA网络技术的应用层规范,包括为分布式控制应用而定义的用户应用进程和用户应用对象,为实现3种应用数据的传输与使用而定义的通信模型和应用服务,以及组态和报警机制及其国际和国内标准化现状。
WIA-FA is a wireless network technology applicable for factory automation,which is selfdeveloped by our country and implements high safe and high available information exchange among automation equipments in factories or plants.This paper focuses on WIA-FA application layer specification,including user application processes(UAPs) and user application objects(UAOs) for implementing distributed control applications,communication models and application services for transferring and operating three kinds of user data,as well as configuration and alarm mechanisms.
