Rau cov tshuab hluav taws xob, kev saib xyuas lub sijhawm yog qhov tseem ceeb heev. Txawm li cas los xij, txij li kev ua haujlwm ntawm lub zog hluav taws xob tso siab rau ntau cov khoom siv uas twb muaj lawm, kev saib xyuas lub sijhawm tiag tiag yog qhov nyuaj heev rau kev ua haujlwm thiab kev saib xyuas cov neeg ua haujlwm. Txawm hais tias feem ntau lub tshuab hluav taws xob muaj kev hloov pauv thiab hloov kho cov phiaj xwm, feem ntau lawv tsis tuaj yeem siv tau vim yog cov peev nyiaj nruj. Rau cov chaw nres tsheb uas muaj peev nyiaj tsawg, qhov kev daws teeb meem zoo tshaj plaws yog los txuas cov txheej txheem uas twb muaj lawm rau IEC 61850 network, uas tuaj yeem txo qhov peev txheej xav tau.
Cov tshuab hluav taws xob uas twb muaj lawm uas tau ua haujlwm tau ntau xyoo tau teeb tsa ntau yam khoom siv raws li cov txheej txheem kev sib txuas lus, thiab hloov tag nrho lawv ib zaug tsis yog qhov kev xaiv zoo tshaj plaws. Yog tias koj xav hloov kho lub zog automation system thiab siv Ethernet-based SCADA system niaj hnub los saib xyuas cov khoom siv hauv teb, yuav ua li cas kom tau txais tus nqi qis tshaj plaws thiab cov khoom siv tib neeg tsawg yog qhov tseem ceeb. Siv cov kev sib txuas sib txuas xws li cov khoom siv sib txuas sib txuas, koj tuaj yeem yooj yim tsim kom muaj kev sib txuas pob tshab ntawm koj IEC 61850-raws li lub zog SCADA system thiab koj cov khoom siv raws tu qauv raws tu qauv. Cov ntaub ntawv pov thawj ntawm cov khoom siv hauv teb tau ntim rau hauv Ethernet cov ntaub ntawv pob ntawv, thiab SCADA system tuaj yeem paub txog kev saib xyuas lub sijhawm ntawm cov khoom siv hauv teb no los ntawm kev tshem tawm.
Moxa's MGate 5119 Series substation-qib lub rooj vag hluav taws xob tau yooj yim siv thiab tsim kom muaj kev sib txuas lus yooj yim. Cov rooj vag no tsis tsuas yog pab kom paub txog kev sib txuas lus ceev ceev ntawm Modbus, DNP3, IEC 60870-5-101, IEC 60870-5-104 cov cuab yeej thiab IEC 61850 kev sib txuas lus network, tab sis kuj txhawb NTP lub sij hawm synchronization muaj nuj nqi kom paub meej tias cov ntaub ntawv muaj sijhawm sib koom ua ke stamp. MGate 5119 series kuj tseem muaj lub tshuab hluav taws xob ua SCL cov ntaub ntawv, uas yooj yim rau kev tsim cov ntaub ntawv substation gateway SCL, thiab koj tsis tas yuav siv sijhawm thiab nyiaj txiag los nrhiav lwm yam cuab yeej.
Rau kev saib xyuas lub sijhawm ntawm cov khoom siv hauv thaj chaw siv cov txheej txheem tsim khoom, Moxa's NPport S9000 series serial device servers kuj tuaj yeem raug xa mus rau txuas serial IEDs rau Ethernet-based infrastructure los txhim kho cov chaw ua haujlwm ib txwm muaj. Cov koob no txhawb nqa txog li 16 qhov chaw nres nkoj thiab 4 Ethernet hloov chaw nres nkoj, uas tuaj yeem ntim cov ntaub ntawv raws tu qauv rau hauv Ethernet pob ntawv, thiab yooj yim txuas cov khoom siv rau SCADA systems. Tsis tas li ntawd, NPPort S9000 series txhawb NTP, SNTP, IEEE 1588v2 PTP, thiab IRIG-B lub sijhawm synchronization ua haujlwm, uas tuaj yeem ua tus kheej synchronize thiab synchronize cov khoom siv uas twb muaj lawm.
Thaum koj ntxiv dag zog rau koj txoj kev saib xyuas thiab tswj cov chaw nres tsheb hauv lub network, koj yuav tsum txhim kho kev ruaj ntseg network ntaus ntawv. Moxa's serial device networking servers thiab protocol gateways tsuas yog cov neeg pab tsim nyog los daws cov teeb meem kev nyab xeeb, pab koj daws ntau yam kev phom sij uas tshwm sim los ntawm kev sib tham hauv teb. Ob lub cuab yeej ua raws li IEC 62443 thiab NERC CIP cov qauv, thiab muaj ntau yam kev ruaj ntseg ua haujlwm los tiv thaiv kev sib txuas lus los ntawm kev ntsuas xws li kev lees paub tus neeg siv, teeb tsa IP daim ntawv tso cai nkag mus, kev teeb tsa thiab kev tswj hwm raws HTTPS thiab TLS v1. 2 raws tu qauv kev ruaj ntseg los ntawm kev siv tsis tau tso cai. Moxa cov kev daws teeb meem tseem niaj hnub ua kev soj ntsuam kev ruaj ntseg tsis zoo thiab siv cov kev ntsuas tsim nyog raws sijhawm txhawm rau txhim kho kev ruaj ntseg ntawm cov khoom siv hauv substation network hauv daim ntawv kev ruaj ntseg thaj ua rau thaj.
Tsis tas li ntawd, Moxa cov khoom siv serial servers thiab cov rooj sib tham raws tu qauv tau ua raws li IEC 61850-3 thiab IEEE 1613 cov qauv, ua kom muaj kev ruaj ntseg network tsis raug cuam tshuam los ntawm ib puag ncig hnyav ntawm substations.
