三、體系特色
全廠易于辦理和保護；
供給全部的網絡支撐功用，能夠使體系操作變得更輕松；
充沛滿意用戶將來擴容、進行特定開發(fā)、接入第三方設備的需要；
體系上層選用以太網，為用戶供給了杰出的開放性構造，能夠輕松滿意用戶將來的擴容需要，然后極好地保護了用戶的出資

導言
    現在，數字化技能獲得日新月異的開展，而且日益滲透到各個范疇。作為通用工業(yè)操控計算機的plc，不論是在功用上仍是在運用范疇方面，都有著從邏輯操控到數字操控、單體操控到運動操控、進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備。
    而跟著PLC運用的迅猛開展，各種高檔操控戰(zhàn)略不得不面對不一樣的目標在大跨距渙散地址下的長途操控運用，怎么完結大規(guī)模散布式運用中各種現場數據傳輸處理及長途操控,長途保護等即是很實踐的疑問，這其間的前提之一即是各種數據包的長途傳輸.
    曾經,有的PLC運用體系中選用了無線數傳電臺通訊來到達長途操控PLC的意圖,可是這種計劃依然存在一些缺點,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。 現在最新運用趨勢是將PLC操控體系與現有GPRS無線通訊網絡技能集成，經過GPRS網絡通訊技能，能夠完結全國,乃至全球規(guī)模內的數據超長途牢靠傳輸，進而到達數據長途剖析處理，長途操控的意圖。
GPRS+PLC計劃長處
    中國移動GPRS體系可供給廣域的無線IP銜接。在移動通訊公司的GPRS事務渠道上構建散布式PLC操控體系，完結PLC的無線數據傳輸具有可充沛運用現有網絡，縮短建造周期，下降建造本錢的長處，而且設備裝置便利、保護簡略。經過對比剖析，咱們挑選中國移動的GPRS體系作為散布式PLC操控體系的數據通訊渠道。
