随着经济社会的不断发展,在信息网络方面对信息的传递和控制的要求也越来越高。Profibus总线技术是作为比较热门和流行的一种工业技术被国际广泛认可,在当前的工业技术领域中发挥着重要的作用,因此,学习与研究Profibus总线技术变得非常有必要性和有意义。本文将以西门子公司S7-300系列PLC控制器和施耐德公司ATV71系列变频器以及四个电机组成的协调控制纺纱系统为例,从系统的硬件构成、工作原理、总线通讯部分、通讯程序的设计、系统的调试与维修等几个方面展开,对Profibus总线通讯技术进行阐述。
With the continuous development of economy and society, the requirements for the transmission and control of information in the information network are also getting higher and higher. Profibus is widely accepted as a kind of popular and popular industrial technology and plays an important role in the current industrial technology field. Therefore, it is very necessary and meaningful to study and research Profibus technology. This article will Siemens S7-300 series PLC controller and Schneider ATV71 series inverter and four motor control spinning system composed of an example, from the system’s hardware structure, working principle, the bus communication part of the communication program design , Debugging and maintenance of the system and several other aspects of the Profibus bus communication technology described.
