摘要
本文主要介绍了PROFIBUS DP从站的多功能化设计方案。该方案使用C8051F021和智能接口芯片SPC3作为硬件平台构建从站。从站在实现PROFIBUS DP总线协议的基础上,既可以采集数字量信号,也可以采集模拟信号,从站还具有信号处理功能,提高了抗干扰能力,保证了传输信号质量。从站能独立完成系统的测控任务,较好地满足分布式控制要求。
Multifunctional design of PROFIBUS DP slave node is presented in this paper. The hardware platform of this station consists of MCU C8051F021 and intelligent interface chip SPC3. Both digital signals and analog signals can be sampled on the basis of the implementation of PROFIBUS DP protocol. Besides, the slave also has the function of digital signal processing to enhance the ability of anti jamming, and improving the quality of signal. As a whole, the slave can achieve the assignment of observe and control independently to meet the demand of distributed control.
