基于AT89C52的PROFIBUS-DP从站的设计

Design of PROFIBUS-DP slave station based on AT89C52

随着PROFIBUS现场总线技术的卓越性能,已经应用于世界范围,并且它已经成为国际八种标准现场总线之一。因而研究PROFIBUS技术,开发PROFIBUS现场总线产品具有重大的意义。本文主要介绍了PROFIBUS与SPC3协议芯片构成PROFIBUS-DP从站,以硬件设计和软件设计两方面概述。

With the outstanding performance of PROFIBUS field bus technology, has been used in the world scope, and it has become one of the eight kinds of standard fieldbus international. Thus the PROFIBUS technology, development of PROFIBUS fieldbus products is of great significance. This paper mainly introduces the PROFIBUS agreement with SPC3 chip PROFIBUS-DP slave station, with description of two aspects of hardware design and software design.
