Research on the Key Diagnosis Technology of PROFIBUS-DP Based on FPGA

Abstract:

This paper analyzes the characteristics of physical layer signals, communication protocols, and the timing of PROFIBUS-DP, at last proposed a kind key technologies diagnosis scheme of PROFIBUS-DP, which based on FPGA. The scheme requires only a few peripheral circuits and use of the FPGA logic synthesis external signal, can be completed in two-way isolation of the physical layer status of DP, data flow direction, baud rate detection and other functions, which can be applied to diagnosis failure of PROFIBUS-DP.
