In order to solve the problems of the communication discontinuity and high data error in the converter application especially in serious electromagnetic environments,and also to guarantee the efficient,timely and reliable transmission in the communication system,this paper introduced the cyclic redundancy check(CRC) in ModBus RTU Protocol,analyzed the rule of error check,proposed the method in software realization and parameter selection.A flow chart for the design in CRC algorithm and the implement in the converter communication are also presented.
