工业自动化程度的愈加深入,集中监控、分散控制成为当今自动化盛行的一种联网工程解决方案。作为自动化大家的西门子,其控制系统S7系列PLC,应用非常广泛,为联网工程提供了分散控制的高可靠解决方案。而如何实现集中监控是提高自动化程度的关键之一,可减少现场监控设备、降低工程成本、减少现场技术人员,实现真正意义上的远程集中监控,实现完全自动化联网。本文在深入分析德国赫优讯net LINK功能和特性的基础上,结合美国知名OPC软件提供商Kepware的OPC Server,通过对污水处理工厂信息化联网工程实例的解剖,针对西门子S7系列PLC集中监控问题,提供了一种简单方便、高可靠性的工厂信息化联网解决方案。
The degree of industrial automation deepens, centralized monitoring and decentralized control become a kind of networking engineering solution prevailing in automation today. As an automation of Siemens, its control system S7 series PLC, a very wide range of applications, networking projects provide decentralized control of highly reliable solutions. And how to achieve centralized monitoring is one of the keys to improve the degree of automation, reduce on-site monitoring equipment, reduce project costs, reduce on-site technical staff, to achieve a true sense of the remote centralized monitoring, to achieve fully automated networking. Based on the in-depth analysis of the functions and features of netlink function in Germany, this paper combines the OPC Server of Kepware, a well-known OPC software provider in the United States. Through the anatomy of the example of networking project of sewage treatment plant informatization, , Provides a simple and convenient, high-reliability factory information networking solutions.
