Daim ntawv no yuav ua kom muaj kev sib piv thiab kev tsom xam ntawm ob lub thev naus laus zis no los ntawm ntau qhov kev xav, ua rau cov neeg nyeem tau nkag siab tob txog lawv qhov sib txawv.
II. Lus Txhais thiab Txheej Txheem
Muaj Ethernet
Industrial Ethernet yog thaj chaw muaj zog thiab chav tsev sib koom ua ke raws li IEEE 802.3 (Ethernet), tshwj xeeb tsim los rau cov ntaub ntawv sib txuas lus thiab xa mus rau hauv kev lag luam automation thiab tswj cov tshuab. Nws sib txuas cov kev ua tau zoo ntawm cov cuab yeej siv Ethernet ib txwm muaj- xws li cov bandwidth siab, muaj kev ntseeg siab, thiab yooj yim scalability-thaum ua kom zoo dua qub thiab txhim kho kom tau raws li qhov tshwj xeeb xav tau ntawm kev lag luam automation. Los ntawm cov qauv kev sib txuas lus raws tu qauv thiab kho vajtse interfaces, Industrial Ethernet enables interconnection thiab kev sib pauv ntaub ntawv ntawm pab kiag li lawm, li no pab tau ntau lawm efficiency thiab txo nqi txij nkawm.
Industrial Fieldbus
Industrial fieldbus yog kev sib txuas lus network raws tu qauv siv hauv kev lag luam automation, feem ntau rau kev sib pauv ntaub ntawv thiab kev sib txuas lus ntawm cov khoom siv. Nws txuas thiab tswj ntau yam khoom siv hauv kev lag luam thiab cov sensors, xws li PLCs (Programmable Logic Controllers), sensors, thiab actuators, yooj yim rau kev xa cov ntaub ntawv thiab kev tswj ntawm cov khoom siv. Lub hom phiaj ntawm kev lag luam fieldbus yog txhawm rau txhim kho kev ua tau zoo, kev ntseeg tau, thiab kev hloov pauv ntawm cov tshuab automation thaum txo cov nqi txhim kho thiab tu. Cov txheej txheem kev lag luam muaj xws li PROFINET, Modbus TCP, thiab EtherNet/IP.
III. Technical Feature Sib piv
Txoj kev sib txuas lus
Industrial Ethernet:Siv lub hnub qub, nplhaib, lossis tsob ntoo topologies los txuas ntau yam khoom siv los ntawm cov keyboards, ua kom muaj kev sib txuas lus thiab kev sib pauv ntaub ntawv. Cov qauv no muab superior scalability thiab kev ntseeg tau.
Industrial Fieldbus:Ua haujlwm ib lub tsheb npav, txuas ntau yam khoom siv ntawm ib lub npav rau kev sib txuas lus thiab kev sib pauv ntaub ntawv. Txawm hais tias yooj yim heev, cov qauv no muaj kev txwv scalability.
Kev sib txuas lus ceev
Industrial Ethernet:Siv cov cuab yeej siv siab - kis tau tus mob ceev, feem ntau ua haujlwm ntawm 100Mbps lossis siab dua, thiab tuaj yeem ncav cuag 1Gbps lossis dhau ntawd. Qhov no ua rau muaj Ethernet ua tau raws li qhov xav tau ntawm cov ntawv thov uas xav tau cov ntaub ntawv sib kis ceev.
Industrial Fieldbus:Feem ntau siv cov kev sib txuas lus sib txuas nrog cov ntaub ntawv qis dua, feem ntau qis dua 10Mbps. Thaum txaus rau cov txheej txheem kev lag luam automation tswj kev xav tau, nws poob qis hauv siab - ceev cov ntaub ntawv kis tau tus mob.
Tiag -Lub Sijhawm Muaj Peev Xwm
Industrial Ethernet:Kev sib tw tsis muaj zog hauv lub sijhawm tiag tiag, tab sis tuaj yeem ua tau raws li lub sijhawm yuav tsum tau nruj los ntawm cov thev naus laus zis tshwj xeeb thiab cov txheej txheem (xws li lub sijhawm synchronization thiab kaw-loop tswj).
Industrial Fieldbus:Feem ntau muaj zog tiag tiag - lub sijhawm ua haujlwm, ua tau raws li qhov tiag - lub sijhawm tswj kev xav tau ntawm kev lag luam automation.
Cov ntaub ntawv ntim
Industrial Ethernet:Haum rau cov xwm txheej uas muaj cov ntaub ntawv loj, muaj peev xwm tuav tau ntau yam ntawm ob qho tib si tiag - sijhawm thiab tsis yog - tiag - cov ntaub ntawv sijhawm.
Industrial Fieldbus:Feem ntau haum rau cov xwm txheej nrog cov ntaub ntawv me me, feem ntau xa cov cim tswj thiab cov ntaub ntawv xwm txheej hauv cov ntaub ntawv luv luv.
Topology
Industrial Ethernet:Txhawb ntau lub topologies, xws li lub hnub qub, lub nplhaib, lossis cov qauv ntoo, kom haum rau cov kev lag luam sib txawv ntawm cov nplai sib txawv thiab qhov nyuaj.
Industrial Fieldbus:Feem ntau ntiav cov qauv tsheb npav, uas muaj qhov yooj yim topology.
Kev ruaj ntseg thiab kev ntseeg siab
Industrial Ethernet:Hais txog kev ruaj ntseg cov ntaub ntawv thiab kev tiv thaiv network los ntawm kev encryption, authentication, thiab kev tswj xyuas kom muaj kev ruaj ntseg network. Redundancy mechanisms thiab txhim khu kev qha network topologies lav cov ntaub ntawv xa mus kev ntseeg tau thiab ruaj khov.
Industrial Fieldbus: Muaj qee qhov kev ruaj ntseg thiab kev ntseeg tau, txawm tias muaj zog me ntsis piv rau Industrial Ethernet.
IV. Daim ntawv thov Domain sib piv
Ob leeg Industrial Ethernet thiab Industrial Fieldbus nrhiav kev siv dav hauv kev lag luam automation, txawm tias txhua tus ua haujlwm tshwj xeeb.
