中矿立磨基于Modbus协议远程通讯研究

Discussion on Remote Communication of Vertical Mill Based on Modbus Protocol

语言并非人类与生俱来的本能,正如人类主要通过语言来进行交流,机器主要也是机器语言来进行数据交换。人类通过逐字逐句交流,有不同语言,每种语言都有自己的语法。而机器之间的串行通讯是通过一个字节或一帧数据来交换信息,机器同样也有不同的通讯协议,每种通讯协议都有自己信息交换的规则。本文主要讲由MODICON公司推出的一种开放式通讯协议MODBUS RTU。

Language is not an innate instinct of human beings.Just as human beings communicate mainly through language,machines also exchange data mainly through machine language.Humans communicate word for word,and there are different languages,each with its own grammar.Serial communication between machines is to exchange information through a byte or a frame of data.Machines also have different communication protocols,and each communication protocol has its own rules for information exchange.This paper focuses on MODBUS RTU,an open communication protocol launched by MODICON.
