通信技术在莱钢120万吨球团的应用

摘要

介绍工业以太网通信技术，重点介绍莱钢120万吨球团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 Wince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。%The paper describes briefly the industrial Ethernet communication technology and highligIlts the hardwarecomposition software composition and connection of system communication of the control system of Laiwu Steel Ten Thousand Tons Iron Pelletizing Plant Siemens PLC is used to form the site-level control system which is realized by Siemens S7 software With SimaticWince as the conifguration software of the upper system and by adopting Ethemet communication technology the vari-Otis site data and parameters are displayed in real time realizing the control of the remote upper computer over the site-levelcontrol system.
