1, Txheej txheem cej luam ntawm PROFINET Cable
Cov kab hluav taws xob siv hauv PROFINET tes hauj lwm feem ntau yog muab faib ua ntau hom, xws li tooj liab Ethernet cables, fiber ntau optic (FO) cables, thiab fais fab ntawm Ethernet (PoE) cables. Kev xaiv ntawm cov cables no feem ntau yog nyob ntawm qhov hnyav ntawm ib puag ncig thiab seb PROFINET IRT (real-time) muaj nuj nqi siv.
2, Copper Ethernet cable
Copper Ethernet cables yog hom kab ntau tshaj plaws hauv PROFINET tes hauj lwm. Lawv feem ntau muaj cov khoom siv ruaj khov thiab tiv thaiv lub tes tsho kom hloov mus rau qhov chaw ua haujlwm hnyav.
Standard Ethernet cable thiab PROFINET cable
Standard Ethernet cables, xws li Cat-5e, feem ntau ua haujlwm zoo hauv chaw ua haujlwm yooj yim. Txawm li cas los xij, nyob rau hauv ib puag ncig kev lag luam hnyav dua, cov cables no yuav tsis tuaj yeem tiv taus siab torsion thiab electromagnetic cuam tshuam (EMI). Yog li ntawd, PROFINET cables tau kho kom zoo dua qub los txhim kho lawv cov kav ntev thiab muaj peev xwm tiv thaiv kev cuam tshuam.
Hom PROFINET tooj liab cables
PROFINET tooj liab cables feem ntau muab faib ua plaub hom: Hom A, Hom B, Hom R, thiab Hom C.
A-hom cable: haum rau kev txhim kho ruaj khov, yuav tsum tsis txhob muaj kev txav tom qab kev debugging.
B-hom cable: haum rau kev teeb tsa uas yuav muaj qhov khoov thiab tuaj yeem tiv taus qee lub sijhawm lossis kev co.
R-hom cable: tailor-made rau neeg hlau daim ntaub ntawv, nrog ntau dua durability thiab yooj.
C-hom cable: siv rau lwm yam tshwj xeeb daim ntawv thov xws li rotating machinery, muaj peev xwm ntawm withstanding motion thiab dynamic ib puag ncig.
Cable qauv thiab cov yam ntxwv
PROFINET tooj liab cables feem ntau txais yuav ib tug 4-hlau los yog 8-core qauv. A 4-hlau cable tuaj yeem txhawb nqa 100 Mbps ceev Ethernet kis tau tus mob thiab tswj cov teeb liab ruaj khov nyob rau hauv qhov deb ntawm 100 meters. Ib qho 8- tub ntxhais cable tuaj yeem siv rau kev sib kis ntawm 1 Gbps. Cov cables no feem ntau tuaj nrog cov sheaths ntsuab thiab ua raws li cov kev qhia tshwj xeeb uas tsim los ntawm PROFIBUS thiab PROFINET International (PI).
Hais txog cov qauv cable, PROFINET cables tau ntxiv aluminium foil shielding txheej thiab braided shielding txheej los tiv thaiv electromagnetic cuam tshuam. Cov cuab yeej txhawb nqa no ua rau PROFINET cables kom muaj kev ruaj ntseg dua thiab kev ntseeg siab hauv cov cheeb tsam hnyav.
3, fiber ntau optic cable
Fiber optic cables yog lwm qhov kev xaiv tseem ceeb rau PROFINET tes hauj lwm. Lawv muaj kev sib kis ntev dua thiab muaj peev xwm tiv thaiv kev cuam tshuam ntau dua, ua rau lawv haum rau cov xwm txheej uas xav tau kev xa mus ntev lossis kev xav tau siab bandwidth.
Hom Fiber Optic Cables
PROFINET fiber optic cables feem ntau muab faib ua ob hom: B-hom thiab C-hom. B-hom cables tsim nyog rau kev siv ruaj khov lossis hloov tau yooj yim, thaum C-hom cables tau tsim tshwj xeeb rau kev siv tshwj xeeb xws li kev txav mus tas li, kev vibration, lossis torsion.
Fiber optic qeb thiab cov yam ntxwv
PROFINET fiber optic cables tuaj yeem siv plaub hom fiber ntau: yas fiber ntau optic (POF), multimode iav fiber ntau, ib hom iav fiber ntau, thiab tawv coated fiber ntau optic (HCF) lossis photonic siv lead ua fiber (PCF) nrog cov tsho yas.
Yas fiber ntau optic: Tus nqi qis, tab sis txwv kev sib kis deb thiab bandwidth.
Multimode iav fiber ntau: haum rau luv luv kis tau tus mob, nrog bandwidth siab.
Ib hom iav fiber ntau: haum rau kev sib kis mus ntev, nrog bandwidth siab dua thiab qis qis.
Hard coated optical fibers los yog photonic siv lead ua fibers: muaj ntau dua durability thiab corrosion kuj, haum rau hnyav ib puag ncig.
Transmission nrug thiab teeb liab refresh
Qhov kev ncua deb ntawm fiber ntau optic cables feem ntau yog ntev tshaj li ntawm cov tooj liab cables. Qee qhov xwm txheej, fiber ntau optic cables tuaj yeem khiav tshaj 100 mais yam tsis xav tau lub teeb liab tshiab. Txawm li cas los xij, nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom lub teeb liab tshiab, cov khoom siv network xws li cov keyboards tuaj yeem siv los txuas ntxiv qhov kev sib kis.
4, Lwm hom cables
Ntxiv nrog rau tooj liab Ethernet cables thiab fiber ntau optic cables, PROFINET kuj txhawb zog tshaj Ethernet (PoE) cables thiab wireless kis technology. PoE cables tso cai rau cov khoom siv kom tau txais lub zog thiab cov ntaub ntawv los ntawm Ethernet cables, ua kom yooj yim ntawm kev ua haujlwm thiab txo cov nqi. Kev xa xov hluav taws xob wireless muab kev yooj yim dua thiab yooj yim dua, tsim nyog rau cov xwm txheej uas kev xaim nyuaj lossis cov khoom siv txawb xav tau.
5, Kev xaiv Cable thiab kev ceev faj txog kev teeb tsa
Thaum xaiv thiab txhim kho PROFINET cables, ntau yam yuav tsum tau xav txog, suav nrog kev sib kis deb, tus nqi sib kis, ib puag ncig, kev cuam tshuam hluav taws xob, thiab lwm yam Nov yog qee qhov kev ceev faj tseem ceeb:
Xaiv hom kab tsim nyog raws li ib puag ncig: A lossis B cable tuaj yeem xaiv rau kev teeb tsa ruaj khov; Yooj yim los yog dynamic installation tuaj yeem xaiv B-hom, R-hom, lossis C-hom cables; Rau cov xwm txheej uas xav tau kev xa mus ntev los yog siab bandwidth, fiber ntau optic cables tuaj yeem xaiv.
Xav txog qhov cuam tshuam ntawm electromagnetic cuam tshuam: tooj liab cables raug cuam tshuam los ntawm electromagnetic cuam tshuam, yog li yuav tsum tau ceev faj thaum mus txog lub zog thiab cov ntaub ntawv cables. Fiber optic cables tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam thiab tsim nyog rau cov xwm txheej uas yuav tsum muaj peev xwm tiv thaiv kev cuam tshuam.
Kev Ntsuas thiab Kev Ntsuas: Thaum lub sijhawm teeb tsa, txhua lub cable yuav tsum tau sim thiab siv tau los xyuas kom meej tias nws ua tau zoo thiab ruaj khov. Qhov no suav nrog kev ntsuas ntsuas xws li kev sib txuas ntawm cable, attenuation, thiab bandwidth.
Kev cob qhia thiab kev txhawb nqa: Cov cables sib txawv yuav xav tau kev cob qhia sib txawv thiab kev txhawb nqa. Yog li ntawd, thaum xaiv cov cables, cov neeg muag khoom lossis cov kws tshaj lij yuav tsum tau sab laj rau kev pab tsim nyog thiab kev taw qhia.
