Ngokufika kwenkathi yedijithali, i-Ethernet yendabuko iye yabonisa kancane kancane ubunzima lapho ibhekene nezidingo zenethiwekhi ezikhulayo kanye nezimo zohlelo lokusebenza eziyinkimbinkimbi.
Isibonelo, i-Ethernet yendabuko isebenzisa ama-twisted pairs ane-core noma ayisishiyagalombili-core ukudluliswa kwedatha, futhi ibanga lokudluliswa ngokuvamile lilinganiselwe ngaphansi kwamamitha ayi-100. Izindleko zokuthunyelwa kwezinsizakusebenza kanye nezinsizakusebenza ziphezulu. Ngesikhathi esifanayo, ngokuthuthuka kanye nokusungulwa kobuchwepheshe, ukwenziwa kwemishini encane nakho kuyindlela esobala ekuthuthukisweni kwamanje kwesayensi nobuchwepheshe. Amadivayisi amaningi avame ukuba mancane futhi abe mancane ngosayizi, futhi ukuthambekela kokwenziwa kwemishini encane kuholela ekusetshenzisweni kwe-interface yedivayisi encane. Izixhumi ze-Ethernet zendabuko zivame ukusebenzisa izixhumi ezinkulu ze-RJ-45, ezinkulu ngosayizi futhi kunzima ukuhlangabezana nezidingo zokwenziwa kwemishini encane.
Ukuvela kobuchwepheshe be-SPE (Single Pair Ethernet) kuphule imikhawulo ye-Ethernet yendabuko ngokwezindleko eziphezulu zokuxhuma izintambo, ibanga lokuxhumana elilinganiselwe, usayizi wesixhumi kanye nokunciphisa imishini. I-SPE (Single Pair Ethernet) ubuchwepheshe benethiwekhi obusetshenziselwa ukuxhumana kwedatha. Idlulisa idatha ngokusebenzisa izintambo ezimbili kuphela. Izinga le-SPE (Single Pair Ethernet) lichaza imininingwane yesendlalelo esingokoqobo kanye nesendlalelo sesixhumanisi sedatha, njengezintambo Izintambo, izixhumi kanye nokudluliselwa kwesignali, njll. Kodwa-ke, iphrothokholi ye-Ethernet isasetshenziswa kusendlalelo senethiwekhi, isendlalelo sokuthutha kanye nesendlalelo sohlelo lokusebenza. Ngakho-ke, i-SPE (Single Pair Ethernet) isalandela izimiso zokuxhumana kanye nemininingwane yephrothokholi ye-Ethernet.
I-Phoenix Contact Electrical SPE Managed Switch
Amaswishi aphethwe yiPhoenix ContactSPE afaneleka kakhulu ezinhlelweni ezahlukene zedijithali kanye nengqalasizinda (ezokuthutha, ukuphakelwa kwamanzi kanye nokugeleza kwamanzi) ezakhiweni, emafektri, kanye nasekusebenzeni ngokuzenzakalela kwezinqubo. Ubuchwepheshe be-SPE (Single Pair Ethernet) bungahlanganiswa kalula nengqalasizinda ye-Ethernet ekhona.
Izici zokusebenza kweswishi ye-Phoenix ContactSPE:
Ø Ukusebenzisa i-SPE standard 10 BASE-T1L, ibanga lokudlulisela lifika ku-1000 m;
Ø Intambo eyodwa idlulisa idatha namandla ngesikhathi esisodwa, izinga lokunikezwa kwamandla le-PoDL: Isigaba 11;
Ø Isebenza kumanethiwekhi e-PROFINET kanye ne-EtherNet/IP™, izinga lokuvumelana kwe-PROFINET: Isigaba B;
Ø Ukusekela ukuphindaphinda kwesistimu ye-PROFINET S2;
Ø Isekela ukuphindaphinda kwenethiwekhi yendandatho njenge-MRP/RSTP/FRD;
Ø Isebenza kuwo wonke umhlaba kumaphrothokholi ahlukahlukene e-Ethernet kanye ne-IP.
