PROFIBUS―DP 现场总线在角钢连轧生产线中的应用PROFIBUS―DP 现场总线在角钢连轧生产线中的应用 摘 要：本文以某型钢厂角钢热连轧生产线控制系统为例，简述了当今较为先进的角钢生产工艺，描述了角钢生产线电气系统的配置，结合角钢生产线的实际情况，介绍了基于 PROFIBUS―DP 现场总线技术的现代化角钢生产线轧机控制系统的软、硬件配置，主站、从站的构成以及使用编程软件 STEP7 对 PROFIBUS―DP 现场总线进行组态的方法。该角钢热连轧生产线以 SIMATIC S7-400 PLC 为主站，6RA70、ET200M 为从站，主站与上位机之间采纳工业以太网连接，主站与从站之间采纳 PROFIBUS―DP 网连接，整个系统是一个全数字、全网络化系统，大大提高了企业自动化控制水平，对类似角钢生产企业的生产线建设、改造有很高的参考价值。 关键词：PROFIBUS―DP；现场总线；生产线 Abstract: This paper uses a type of steel angle steel hot continuous rolling production line control system as an example, introduces the advanced angle production technology, describes the angle steel production line electrical system configuration angle, with the actual situation in the production line, introduced based on the PROFIBUS and DP field bus technology of the modern steel production line rolling mill control system software and hardware configuration, the master station, from the station and the composition of the use of programming software STEP7 on PROFIBUS - DP field bus configuration method. The angle steel hot continuous rolling production line to SIMATIC S7-400 PLC for the 6RA70, ET200M, from the station, the master station and between machine adopts industrial Ethernet connection, between master station and slave station by PROFIBUS - DP network connection, the whole system is a fully digital, networked system, greatly improving the enterprise automation control level, similar to the angle steel production line construction, renovation has a very high reference value.
