Implementation of Serial Communication between Siemens Masterdrives Transducer and Industrial PC

Motor running in special case by between PC and transducer is often meet in electric drive areas. The paper researches network communication based on RS 485 between Siemens Masterdrives and industrial PC. The structure and characteristic of USS protocol is introduced, the hardware connection and parameter setting are given. At last, parts of program of communication is provided. The application shows that this method is simply, reliable and stable.
