摘要
针对大型分布式工业控制系统中PLC控制器位置分散等实际情况,本文采用工业以太网构建PLC集中采集监控网络。考虑控制系统中存在不同品牌PLC控制器,接口和通讯协议各不相同,开发了基于C#的PLC数据集中采集监控系统。工程应用表明:系统实现了工业现场中多个PLC控制设备的数据采集和监控,并提供了短信报警功能。同时通过与数据库技术的相互融合,实现了控制系统内数据的分析和处理,便于管理人员及时掌握企业设备的运行信息。
In view of the decentralized position of PLC controller in large distributed industrial control system and the inability of centralized acquisition and monitoring,a centralized acquisition and monitoring network of PLC is constructed by using Modbus communication protocol in ethernet.Considering the existence of different brand PLC controllers and different communication protocols in the system,a centralized collection and monitoring system for PLC data based on C#is developed.Engineering application shows that the system realizes data acquisition and monitoring of multiple PLC devices in industrial field,and provides short message alarm function.At the same time,through the integration with database technology,the efficient acquisition and processing of data in the control system is realized,which is convenient for managers to grasp the operation information of enterprise equipment in time.
