In order to solve the problem of difficult communication conversion between different devices in industrial control, a PROFIBUS-DP fieldbus communication conversion interface was developed, which enables devices with RS485 interface to connect to the PROFIBUS-DP network as slaves to complete communication and control functions. This paper mainly introduces the hardware and software implementation of the PROFIBUS-DP communication conversion interface. Keywords: PROFIBUS-DP; interface; SPC3; single chip computer The Development of PROFIBUS-DP Communication Transform Interface Zhou Xiao-hui, Meng Yan-jing, Xu De-yu (College of Electric and Electronic Engineering; Shaanxi University of Science & Technology; Xianyang; Shaanxi; 712081) Abstract: In view of the communication transform problem in the industry control, a PROFIBUS-DP communication transform interface is developed. This interface can connect the device that provided with RS485 interface to the PROFIBUS-DP, and carry out communication and control functions. In this paper, designing method of the hardware and software is discussed about PROFIBUS-DP communication transform interface.Key words: PROFIBUS-DP; interface; SPC3; single chip computer
