基于雙線以太網(wǎng)技術(shù)的Modbus/TCP網(wǎng)關(guān)系統(tǒng)研究

摘要： 針對雙線以太網(wǎng)新環(huán)境下兼容性問題，研究基于雙線以太網(wǎng)技術(shù)的工業(yè)以太網(wǎng)網(wǎng)關(guān)系統(tǒng)。采用典型的工業(yè)以太網(wǎng)通信協(xié)議Modbus/TCP作為網(wǎng)關(guān)系統(tǒng)接收數(shù)據(jù)協(xié)議，選取CAN、RS485/串口、MQTT等典型通信接口或協(xié)議作為網(wǎng)關(guān)系統(tǒng)轉(zhuǎn)發(fā)對象的方案。實驗采用實物搭建驗證環(huán)境，驗證雙線以太網(wǎng)網(wǎng)關(guān)系統(tǒng)不同平臺接口轉(zhuǎn)發(fā)數(shù)據(jù)功能，實驗結(jié)果表明雙線以太網(wǎng)網(wǎng)關(guān)系統(tǒng)能通過雙線以太網(wǎng)接口正常接收Modbu...
