EtherNet/IP工业以太网在制丝线控制系统中的应用

Application of Industrial Ethernet in Control System in Primary Processing Line

根据工业以太网技术的发展和企业信息化、现场控制的要求,在武汉卷烟厂2400kg/h制丝线控制系统中从现场设备到信息管理层全面应用了基于EtherNet/IP的工业以太网技术。详细讨论了系统网络结构,控制层、现场设备层、信息管理层的配置,以及网络和系统安全设置。基于工业以太网的制丝线控制系统易于集成扩展、维护方便,克服了传统现场总线应用中的缺点,其应用表明,EtherNet/IP工业以太网可以满足制丝线现场设备控制的实时性和可靠性。

Taking account of the development of Industrial Ethernet technology and the requirements of information management and field control, the Industrial Ethernet technology was applied all round from field equipment to information management level in the control system in the 2400kg/h primary processing line of Wuhan Cigarette Factory. The network structure, configurations of control level, field equipment level and information management level, and the security setting of the network and system were discussed. The Industrial Ethernet based control system in primary processing line was easy to integration, extension and maintenance and free from the shortcomings associated with traditional field bus. The practical application showed that Industrial Ethernet based control is real time and reliable, it satisfies the requirements of field equipment control in primary processing line.
