现场总线技术是当今工业自动化领域的尖端技术,它代表并引领着工业控制的发展方向。本文对该技术在连铸机关键设备拉坯矫直机和结晶器振动装置上的应用做一深入浅出的阐述:从PROFIBUS的特点到现场的网络构成,从PLC硬件的组态到STEP7软件的设置,控制字的编制与发送,网络适配器的功能特点,驱动变频器的EMC安装及参数设置都做了详细的说明。最后,对改造后的现场总线控制系统出现的问题做了分析,提出了解决方案。
Fieldbus technology is the cutting-edge technology in today’s industrial automation, which represents and leads the direction of industrial control. In this paper, the application of the technology in the casting machine straightening machine and mold vibration device make a simple and profound exposition: from the characteristics of PROFIBUS to the network structure of the site, from the configuration of PLC hardware to the setting of STEP7 software , The control word preparation and sending, the network adapter’s function characteristic, the drive frequency changer EMC installment and the parameter hypothesis has made the detailed explanation. Finally, the problems that occurred in the reconstructed fieldbus control system are analyzed and the solutions are put forward.
