Profibus DP从站冗余技术及其实现

摘要

针对市场上对高可靠性Profibus DP控制系统需求,研究了相关国际标准,采用SPC3链路层控制器作为核心芯片,进行软硬件协同设计,开发出符合PNO标准＜Specification Slave Redundancy V1.2＞要求的从站冗余协议栈.%Aim to the requirement for high reliable Profibus DP control system in the market, this paper research on relative international standards, adopt SPC3 link layer controller as core chip, make sofeware and hardware co-design, and finally develop a new DP slave redundancy protocol stack which meets the < Specification Slave Redundancy V1.2 >.
