本文介绍了WIA-PA网络在化工行业的一个具体应用实例。通过对化工厂的实际需求进行分析之后,实施了WIA网络,包括无线的温度、压力变送器,无线4-20mA执行器,并且通过modbus协议接入到控制系统。实际运行的效果表明,WIA-PA网络用于过程工业中,具有得天独厚的优势。同时,该系统中首次将WIA网络用于控制,也做了一次大胆的尝试,从结果上看,WIA网络用在一些非关键控制中,也具有良好的效果。
This article describes a WIA-PA network in the chemical industry a specific application example. After analyzing the actual needs of the chemical plant, WIA networks were implemented, including wireless temperature and pressure transmitters, wireless 4-20mA actuators, and access to the control system via the modbus protocol. The results of the actual operation show that the WIA-PA network is used in the process industry and has a unique advantage. At the same time, for the first time, the system uses WIA network for control and has also made a bold attempt. From the result point of view, the WIA network is used in some non-critical control and has good effect.
