| Abstract: | By studying the protocols and data transmission modes of Profibus-DP and CAN bus,a method of fieldbus protocol conversion has been proposed.Basing on this study,hardware and software of the protocol conversion gateway have been designed.In order to simplify the design and improve the performance,the ARM9-based high performance Micro Processor was adopted as the main control chip,and the SPC3 and SJA1000 were used as the protocol chip and control chip separately.The experimental results showed that the CAN bus device can be linked to the Profibus-DP bus successfully and the performance indicators met the requirements of design.This gateway has good performance in real-time and reliability. |
