Abstract

The invention provides a card and a method for converting communication protocols. The card and the method have the advantages that the diversified communication protocols can be adopted for a plurality of second devices, data can be received by a plurality of communication interfaces, can be forwarded to an MCU (micro-control unit) and then are respectively analyzed and converted by the MCU, then the second devices can be communicated with first devices via CPLD (complex programmable logic device) and hardware interfaces, and accordingly the communication protocols can be simultaneously transmitted and exchanged by the single card for converting the communication protocols; another card for converting the communication protocols in the prior art can be omitted, and accordingly problems of high cost and multiple interfaces in procedures for converting diversified protocols in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of industrial communication, in particular to a communication protocol conversion card and a communication protocol conversion method. Background technique [0002] The communication protocol conversion card is a communication card that can be used to realize data transmission and exchange between two devices (such as frequency converter and communication master station). The communication protocol conversion cards currently on the market usually can only realize the conversion of one communication protocol. [0003] However, in the actual application of the communication protocol conversion card, there may be a need to realize redundant control with two or more communication protocols, or to realize the need for debugging and monitoring the system without interrupting the system control; This requires the communication protocol conversion card to be able to convert two or more communication protocols at th...
