Nekuuya kwenguva yedhijitari, Ethernet yechinyakare yakaratidza zvishoma nezvishoma mamwe matambudziko painosangana nezvinodiwa zve network zviri kukura uye mamiriro ezvinhu akaoma ekushandisa.
Semuenzaniso, Ethernet yechinyakare inoshandisa ma "twisted pairs" mana kana masere-core pakutumira data, uye daro rekutumira rinowanzo ganhurira pasi pemamita zana. Mutengo wekushandisa vanhu nezvinhu zvekushandisa wakakwira. Panguva imwe chete, nekufambira mberi uye kuvandudzwa kwetekinoroji, "miniaturization" yemidziyo inyaya iri pachena mukuvandudzwa kwesainzi netekinoroji pari zvino. Midziyo yakawanda inowanzova midiki uye midiki muhukuru, uye maitiro e "device miniaturization" anotungamira "miniaturization" ye "device interfaces". "Traditional Ethernet interfaces" inowanzo shandisa RJ-45 connectors dzakakura, idzo dzakakura muhukuru uye dzakaoma kusangana nezvinodiwa ne "device miniaturization".
Kubuda kwetekinoroji yeSPE (Single Pair Ethernet) kwakaputsa miganho yeEthernet yechinyakare maererano nemitengo yakakwira yewaya, daro diki rekutaurirana, saizi yeinterface uye miniaturization yemidziyo. SPE (Single Pair Ethernet) itekinoroji yenetwork inoshandiswa pakutaurirana kwedata. Inotumira data nekushandisa tambo mbiri chete. Standard yeSPE (Single Pair Ethernet) inotsanangura marongero e physical layer ne data link layer, senge waya Cables, connectors uye signal transmission, nezvimwewo. Zvisinei, Ethernet protocol ichiri kushandiswa mu network layer, transport layer uye application layer. Saka, SPE (Single Pair Ethernet) ichiri kutevedzera misimboti yekutaurirana uye marongero eprotocol eEthernet.
Phoenix Bata Nemagetsi SPE Inodzorwa Switch
Maswichi anofambiswa nePhoenix ContactSPE akanakira mashandisirwo akasiyana-siyana edhijitari uye zvivakwa (zvekufambisa, kupa mvura uye kudhonza mvura) muzvivakwa, mafekitori, uye otomatiki yemaitiro. Tekinoroji yeSPE (Single Pair Ethernet) inogona kubatanidzwa zviri nyore muzvivakwa zveEthernet zviripo.
Mashandiro ekushanda kwePhoenix ContactSPE switch:
Ø Uchishandisa SPE standard 10 BASE-T1L, daro rekutumira rinosvika 1000 m;
Ø Waya imwe chete inotumira data nemagetsi panguva imwe chete, PoDL power supply level: Kirasi 11;
Ø Inoshanda kune network dzePROFINET neEtherNet/IP™, PROFINET conformance level: Kirasi B;
Ø Tsigira PROFINET S2 system redundancy;
Ø Inotsigira kudzokororwa kwenetwork yeringi senge MRP/RSTP/FRD;
Ø Inoshanda pasi rose kune akasiyana mapuroteni eEthernet neIP.
