摘要
以机电一体化控制系统为例介绍了Profibus-DP现场总线在机电一体化中的应用,重点阐述了机电一体化系统各站点的功能、Profibus-DP总线的控制方案、控制特点以及控制的技术实现原理。整个系统的控制器采用Siemens的S7-300作为主站,9个S7-200和变频器作为从站,监控整条生产线的生产过程,通过Profibus-DP总线实现了对整个系统的集中控制,又能分散控制各底层设备,从而实现集中与分布式相结合的灵活控制模式。该方案的实施提高了整个控制系统运行的可靠性,实现了多速控制。
With an electromechanical integration control system as an example,the application of Profibus-DP is illustrated,emphasizing on the functions of each station and the control scheme,control characteristic and implementation principle of Profibus- DP. Siemens S7- 300 controller is adopted as the master station,and nine S7- 200 s and one converter as the slave stations,monitoring and controlling the whole production process. It controls whole system as well as the field equipment via Profibus-DP,implementing flexibly the centralized and distributed control,realizing the multi-speed control and enhancing the operational stability.
