Protocol converter, and protocol conversion system and method

Abstract

The invention discloses a protocol converter which is used for carrying out information exchange on a first master station and a second master station, and protocols of the first master station and the second master station are different. The protocol converter comprises a conversion chip, and a first network slave station protocol module and a second network master station protocol module which are in communication connection with the conversion chip; the first network slave station protocol module is used for receiving first protocol data sent by a first master station and transmitting the first protocol data to the conversion chip. The conversion chip is used for converting the first protocol data into second protocol data identified by the first master station and sending the second protocol data to the second network master station protocol module, and the conversion chip carries out IO configuration and is used for mapping the corresponding relation between IO data received by the first network slave station protocol module and IO data sent by the second network master station protocol module. The second network master station protocol module is in communication connection with a second master station, and the second network master station protocol module is used for transmitting second protocol data to the second master station. The invention further discloses a conversion system and method comprising the converter.
