以太网通信技术在峨口铁矿球团厂的应用

简要介绍工业以太网通信技术，重点介绍太钢峨口铁矿球团厂控制系统的硬件组成、软件组成、系统通信的连接。通过西门子PLC组成现场级控制系统，由西门子S7软件实现控制。以Simatic Wincc作为上位机组态软件，通过以太网通信技术，实时显示现场的各种数据及参数，从而实现上位机对现场级的远程监控。该网络投用以来，运行稳定可靠，故障率为零，很好地满足了工艺对控制的快速性和实时性要求。

Application of Ethernet Communication Technology in Ekou Iron Pelletizing Plant

The paper describes briefly the industrial Ethernet communication technology and highlights the hardware composition, software composition and connection of system communication of the control system of Tai Steel Ekou Iron Pelletizing Plant. Siemens PLC is used to form the site-level control system which is realized by Siemens S7 software. With Simatic Wincc as the configuration software of the upper system and by adopting Ethernet communication technology, the various site data and parameters are displayed in real time, realizing the control of the remote upper computer over the site-level control system. This network has been running stably and reliably since putting into use, with a zero fault rate, well satisfying the requirement of a rapid real-time control of the process.
