Pamene nthawi ya digito yayamba, Ethernet yachikhalidwe yawonetsa pang'onopang'ono mavuto ena akamakumana ndi zofunikira za netiweki zomwe zikukula komanso zovuta kugwiritsa ntchito.
Mwachitsanzo, Ethernet yachikhalidwe imagwiritsa ntchito mawiri opindika anayi kapena asanu ndi atatu potumiza deta, ndipo mtunda wotumizira nthawi zambiri umakhala wochepera mamita 100. Mtengo wotumizira anthu ndi zinthu zakuthupi ndi wokwera. Nthawi yomweyo, ndi kupita patsogolo ndi kupanga zatsopano kwa ukadaulo, kuchepetsera zida ndi njira yodziwikiratu pakukula kwa sayansi ndi ukadaulo. Zipangizo zambiri zimakhala zazing'ono komanso zazing'ono, ndipo chizolowezi cha kuchepetsera zida chimayendetsa kuchepetsera ma interface a chipangizo. Ma interface achikhalidwe a Ethernet nthawi zambiri amagwiritsa ntchito zolumikizira zazikulu za RJ-45, zomwe zimakhala zazikulu komanso zovuta kukwaniritsa zosowa za kuchepetsera zida.
Kubwera kwa ukadaulo wa SPE (Single Pair Ethernet) kwaphwanya malire a Ethernet yachikhalidwe pankhani ya ndalama zambiri zolumikizirana, mtunda wocheperako wolumikizirana, kukula kwa mawonekedwe ndi kuchepetsedwa kwa zida. SPE (Single Pair Ethernet) ndi ukadaulo wa netiweki womwe umagwiritsidwa ntchito polumikizirana deta. Umatumiza deta pogwiritsa ntchito zingwe ziwiri zokha. Muyezo wa SPE (Single Pair Ethernet) umatanthauzira zofunikira za gawo lakuthupi ndi gawo lolumikizirana deta, monga zingwe za waya, zolumikizira ndi kutumiza chizindikiro, ndi zina zotero. Komabe, protocol ya Ethernet imagwiritsidwabe ntchito mu gawo la netiweki, gawo loyendera ndi gawo logwiritsira ntchito. Chifukwa chake, SPE (Single Pair Ethernet) imatsatirabe mfundo zolumikizirana ndi zofunikira za protocol ya Ethernet.
Phoenix Contact Electrical SPE Managed Switch
Ma switch oyendetsedwa ndi Phoenix ContactSPE ndi abwino kwambiri pa ntchito zosiyanasiyana za digito ndi zomangamanga (zoyendera, madzi ndi ngalande) m'nyumba, mafakitale, ndi makina oyendetsera ntchito. Ukadaulo wa SPE (Single Pair Ethernet) ukhoza kuphatikizidwa mosavuta mu zomangamanga za Ethernet zomwe zilipo.
Mawonekedwe a Phoenix ContactSPE switch:
Pogwiritsa ntchito muyezo wa SPE 10 BASE-T1L, mtunda wotumizira ndi wofika mamita 1000;
Ø Waya imodzi imatumiza deta ndi mphamvu nthawi imodzi, mulingo wamagetsi wa PoDL: Gulu 11;
Ø Imagwira ntchito pa ma network a PROFINET ndi EtherNet/IP™, mulingo wogwirizana ndi PROFINET: Gulu B;
Ø Thandizani kuchulukitsa kwa dongosolo la PROFINET S2;
Ø Imathandizira kuchulukirachulukira kwa netiweki ya mphete monga MRP/RSTP/FRD;
Ø Yogwiritsidwa ntchito padziko lonse lapansi pa ma protocol osiyanasiyana a Ethernet ndi IP.
