ControlNet區(qū)別于傳統(tǒng)網(wǎng)絡(luò)的一個顯著特點就是其確定性,由于ControlNet采用了生產(chǎn)者/消費者的網(wǎng)絡(luò)模式,使得其網(wǎng)絡(luò)速度和效率不隨網(wǎng)絡(luò)上節(jié)點數(shù)目和網(wǎng)絡(luò)距離而變化,并且用戶可以預(yù)先組態(tài)網(wǎng)絡(luò)上節(jié)點的信息傳輸時間(毫秒級),使用者無需編寫通訊程序便可確保全部信息在預(yù)先設(shè)定的時間間隔內(nèi)得到傳輸。ControlNet采用的時間片技術(shù)從原理上杜絕了網(wǎng)絡(luò)發(fā)生阻塞的可能。確定性和可重復(fù)性在現(xiàn)代控制系統(tǒng)中得到了越來越多的應(yīng)用。
五、靈活性
ControlNet具有靈活的拓?fù)浣Y(jié)構(gòu),它可以方便地構(gòu)成星型、樹型、總線型和環(huán)形的拓?fù)浣Y(jié)構(gòu);距離可長達成30公里。ControlNet可以采用多家廠商提供的通訊介質(zhì),包括適用于各種環(huán)境的同軸,光纖電纜。
ControlNet是一個本質(zhì)安全的網(wǎng)絡(luò),它可以應(yīng)用于各種環(huán)境場合。Damon/IEC Div. CU-5000 Centrifuge New, never been used
