Koj paub dab tsi txogYam muaj hauj lwm Ethernet? Koj puas paub qhov sib txawv ntawm nws thiab ethernet? Koj puas tau kov ibkhoomNrog ib qho kev lag luam Ethernetkev sib tshuam? Koj puas tau pom cov qauv? Hauv tsab xov xwm no, koj yuav kawm txog lub hauv paus chiv keeb ntawm kev siv Ethernet, peb lub ntsiab ntawm cov Ethernet thiab lawv cov ntawv thov.
1. Keeb kwm ntawm cov ethernet
Vim yog txoj kev loj hlob ntawmCov Ntaub Ntawv Tshuab, kev sib txuas lusTau dhau los ua tus yuam sij rau kev tswj hwm lub sijhawm tiag tiag, qhov xav tau tsim kev sib koom ua ke, qhib kev sib txuas lus, tab sis tus teb tsis tau muaj ua tiav qhov kev thov no.
Txawm hais tias tib daim teb zoo tib yam tau hloov tau thiab cuam tshuam nrog kev sib txuas lus nyuaj, nruab nrab kuj xav tau txoj kev sib txuas lus los ntawm ob txoj kev cai. Qhov no ua rau cov nqi siab, cov cuab yeej siv nyuaj thiab qhov tsis yooj yim zoo.
Muaj Ethernet tau yog li yug!
Raws li peb txhua tus paub, kev lag luam Ethernet los ntawm ethernet. Feem ntau, ethernet yog siv nyob rau hauvKev Tswj Xyuas Lub Tshuab, thiab qhov nolub networkyog hu ua Ethernet. Yuav kom muaj kev tshaj lij ntau dua thiab tshwj xeeb, kev lag luam Ethernet yog faib cov qauv kev tswj hwm lub sijhawm thiab cov khoom siv kis tau loj.
Nws tau txais CSMA / CD raws tu qauv thiab tau sib haum nrog TCP / IP raws tu qauv tib lub sijhawm. Piv nrog rau ib yam dab tsi ethernet, muaj Ethernet Ethernet yuav tsum daws ntau yam teeb meem xws li qhib siab, tiag tiag, synchronization, kev ntseeg tau, tiv thaiv kev cuam tshuam, kev tiv thaiv, tiv thaiv kev cuam tshuam, kev tiv thaiv, tiv thaiv kev cuam tshuam, kev tiv thaiv, tiv thaiv kev cuam tshuam, kev tiv thaiv, tiv thaiv kev cuam tshuam, kev tiv thaiv, tiv thaiv kev cuam tshuam, kev tiv thaiv, tiv thaiv kev cuam tshuam, kev tiv thaiv kev tiv thaiv, kev tiv thaiv thiab kev tiv thaiv kev tiv thaiv. Yog li ntawd, nws tau txais ntau dua thiab ntau dua hauv kev hloov kho tau.
2. Peb hom ntawm cov ntsiab lus ethernet
Muaj ntau ntau lub ntsiab lus ethernet nyob hauv cov teb tam sim no, xws li: ProCinet, Ethernet / ip, ethercat, sercosiii thiab lwm yam. Kab lus no tsuas yog qhia peb hom.
1) ethercat:Lub ntsiab tseem ceeb ntawm ethercat yog tias txhua tus qhev tau sib koom tes muaj peev xwm rho tawm cov ntaub ntawv cuam tshuam nrog cov ntaub ntawv cuam tshuam tau los ntawm cov ntaub ntawv tsim nyog los ntawm cov ntaub ntawv eternet, txiav txim siab rau lawv, thiab Tom qab ntawv luam cov txheej txheem cov ntaub ntawv rau cov khoom siv tom qab. Nws muaj tus tswv-qhev cov ntsiab lus sib pauv cov ntsiab lus, uas yuav tsum tau tus tswv thiab qhev los ua haujlwm ua ke, ua rau ethercat zoo tagnrho rau kev sib txuas lus ntawm tus tswv thiab qhevCov Sawv dawsCov. Nws txhim kho lub sijhawm ua haujlwm tiag tiag ntawm cov kab ke thiab cov tolyology yooj yim tib lub sijhawm, tus nqi tsis yog siab dua tus nqi ntawm kev siv cov teb.
2) Ethernet / IP:Siv cov txheej ntawm lub cev ntawm eternet, cov ntaub ntawv txuas txheej thiab TCP / IP raws tucocol. Nws yog qhov siv dav siv-txheej muaj ethernet raws tu qauv muaj feem ntau los ntawm rockwell automation. Tso cai rau cov khoom siv muaj kev hloov pauv sijhawm-tseem ceeb thov cov ntaub ntawv xws lisensors, actuage,tus hlau, etc. Nws tuaj yeem txhawb nqa tus naj npawb tsis muaj nqis uas yog vim nws tus qauv Ethernet hloov. Nws lub luag haujlwm tseem ceeb yog peb, ib qho yog kev tswj lub sijhawm tiag tiag: raws li cov ntaub ntawv teeb tsa khaws cia hauv tus tswj hwm lossistxawj ntsentaus ntawv, kev tswj lub sijhawm tiag tiag tuaj yeem pom tau los ntawm lub xeev kev hloov pauv hauvKev Sib Txuas Lus Sib Tw; Qhov thib ob yog network configuration: los ntawm lub tsheb npav tuaj yeem paub qhov teeb tsa ntawm tib txheej txheej network, tab sis kuj tuaj yeem paub qhov teeb tsa ntawm cov txheej qis dua; Qhov thib peb yog cov ntaub ntawv tau txais: tuaj yeem yog ua raws li tsim los yog daim ntawv thov yuav tsum tau yooj yim kom paub cov ntaub ntawv tau txais.
(3) profinet:yog siv rau profibus sib xyaw ua ke, qhib, sib koom ua tiav cov kab ke cov kev daws teeb meem los ntawm ethernet thiab enterned cov ntaub ntawv pabcuam kev tswj hwm kev siv automation rau ib. Nws muaj peev xwm ua tau raws li cov neeg siv cov khoom tshiab thiab cov khoom siv uas tau xav tau, hloov kho lub sijhawm tiag tiag, faib cov cuab yeej siv, muaj kev nyab xeeb, thiab Cyber-kev ruaj ntseg, uas yog qhov kubcov ntsiabNyob rau hauv cov tshuab automatation teb tam sim no. Ntxiv rau, nws tau tshaj nrog Ethernet muaj Ethernet thiab cov teb chaws Ethernet (piv txwv li Profibus) thev naus laus zis, tiv thaiv kev nqis peev uas twb muaj lawm.
