Abstract

This paper analyzes the PROFIBUS-DP and physical layer signals states, DP time series and other characteristics. In the past, PROFIBUS-DP HUB common problems of poor universal apply, shape communication is more time-consuming, required message analysis, Drop frame etc, this paper propose a new design of PROFIBUS-DP HUB which based on FPGA. The design contain a detector which used to monitor the physical layer signal state of the DP bus, use of FPGA synthesis logic signal, could control the direction of data flow in the physical layer, and Unrelated with the upper layer protocol, without message analysis, compliance the protocol which used the standard RS-485, and baudrate-adaptive.
