| Abstract: | An interface module with high-speed communication was designed based on Profibus-DP protocol chip and 32 bit ARM chip.The tightly integrated magnetic isolated bus transceiver was used to instead of traditional RS-485 drive circuit.The ESD protection circuit was specially designed to meet the industrial field request.It was packaged for general-purpose device communication protocol by adopting DP’s physical layer,data link layer and part of the application layer protocol.The good characteristics of the module were summarized with an example. |
