Abstract

PROFINET is the latest real-time Ethernet standard based on industrial automation. It has high real-time performance which is recognized the future standard of the industrial field bus communication. This article mainly expounds the development history and research status of PROFINET; Studied and analyzed the PROFINET protocol, real-time , communication relations and data frames; Through the PC card CIFX-50-RE and COMX module of Hilscher, the PROFINET communication link is established, using the SYcon.net software to configure these cards, and through CIFX TEST software has realized the PROFINET data transmit and receive correctly; with the help of Wireshark software we grab the  PROFINET data frame and do the analysis; using API functions provided by the company of Hilscher on the basis of the original code to write the c++ communication test procedure, and the test results is satisfactory. 

This topic carried on the thorough analysis of PROFINET，which do a good stage for PROFINET device development and putting on the market.
