體系上層選用以太網(wǎng)，為用戶供給了杰出的開放性構(gòu)造，能夠輕松滿意用戶將來的擴(kuò)容需要，然后極好地保護(hù)了用戶的出資

導(dǎo)言
    現(xiàn)在，數(shù)字化技能獲得日新月異的開展，而且日益滲透到各個(gè)范疇。作為通用工業(yè)操控計(jì)算機(jī)的plc，不論是在功用上仍是在運(yùn)用范疇方面，都有著從邏輯操控到數(shù)字操控、單體操控到運(yùn)動(dòng)操控、進(jìn)程操控到集散操控的飛躍，今日的可編程序操控器PLC正變成工業(yè)操控范疇的干流操控設(shè)備。
    而跟著PLC運(yùn)用的迅猛開展，各種高檔操控戰(zhàn)略不得不面對(duì)不一樣的目標(biāo)在大跨距渙散地址下的長(zhǎng)途操控運(yùn)用，怎么完結(jié)大規(guī)模散布式運(yùn)用中各種現(xiàn)場(chǎng)數(shù)據(jù)傳輸處理及長(zhǎng)途操控,長(zhǎng)途保護(hù)等即是很實(shí)踐的疑問，這其間的前提之一即是各種數(shù)據(jù)包的長(zhǎng)途傳輸.
    曾經(jīng),有的PLC運(yùn)用體系中選用了無線數(shù)傳電臺(tái)通訊來到達(dá)長(zhǎng)途操控PLC的意圖,可是這種計(jì)劃依然存在一些缺點(diǎn),首要即是其散布規(guī)模依然較為有限,而且跟著通訊間隔的添加,其牢靠性遭到很大影響。 現(xiàn)在最新運(yùn)用趨勢(shì)是將PLC操控體系與現(xiàn)有GPRS無線通訊網(wǎng)絡(luò)技能集成，經(jīng)過GPRS網(wǎng)絡(luò)通訊技能，能夠完結(jié)全國(guó),乃至全球規(guī)模內(nèi)的數(shù)據(jù)超長(zhǎng)途牢靠傳輸，進(jìn)而到達(dá)數(shù)據(jù)長(zhǎng)途剖析處理，長(zhǎng)途操控的意圖。
GPRS+PLC計(jì)劃長(zhǎng)處
    中國(guó)移動(dòng)GPRS體系可供給廣域的無線IP銜接。在移動(dòng)通訊公司的GPRS事務(wù)渠道上構(gòu)建散布式PLC操控體系，完結(jié)PLC的無線數(shù)據(jù)傳輸具有可充沛運(yùn)用現(xiàn)有網(wǎng)絡(luò)，縮短建造周期，下降建造本錢的長(zhǎng)處，而且設(shè)備裝置便利、保護(hù)簡(jiǎn)略。經(jīng)過對(duì)比剖析，咱們挑選中國(guó)移動(dòng)的GPRS體系作為散布式PLC操控體系的數(shù)據(jù)通訊渠道。
