A kind of gateway's hardware solution for integrating PROFIBUS PA into PROFINET

As an international field bus standard, PROFIBUS PA is widely used around the world. The process automation control based on PROFIBUS PA that is integrated into PROFINET of industrial Ethernet is the requirement of comprehensive application for the function expansion. In this paper, a hardware solution of the gateway that is used for the connection between PROFINET based on ERTEC 200, FBC0409 and SIM1-2 and PROFIBUS PA is proposed. It is proved that the scheme completely meets the requirements of relevant standards. Test results demonstrate that the key benefits of the gateway are low cost, improved capacity, and short transmission delay
