指南電力系統(tǒng)104規(guī)約報(bào)文解析

1、指南電力系統(tǒng)104規(guī)約報(bào)文剖析基本定義:端口號(hào)2404，站端為Server控端為Client，平衡式傳輸，2Byte站地址，2Byte傳達(dá)原因，3Byte信息地址。不涉及鏈路層，也沒有一、二級(jí)數(shù)據(jù)之說。104規(guī)約可以簡(jiǎn)單理解成網(wǎng)絡(luò)版的101規(guī)約。他是建立在TCP/IP層之上，可以把他以為是會(huì)話層的的規(guī)約(我是這么理解的)。在串口通訊程序中我們要自己寫程序，用校驗(yàn)體系來保證及判斷報(bào)文的完滿性(屬于鏈路層的東西);用重發(fā)體系保證報(bào)文不扔掉(網(wǎng)絡(luò)層或傳輸層的東西)。而在網(wǎng)絡(luò)通訊中，這些功能都由基層的TCP/IP協(xié)議完成了，所以，我們就不用關(guān)心再校驗(yàn)，丟包等問題了。被控站需要在連接成功后，接到STAR
