Rau cov tshuab fais fab, kev saib xyuas lub sijhawm tiag tiag yog qhov tseem ceeb heev. Txawm li cas los xij, vim tias kev ua haujlwm ntawm lub tshuab fais fab vam khom ntau yam khoom siv uas twb muaj lawm, kev saib xyuas lub sijhawm tiag tiag yog qhov nyuaj heev rau cov neeg ua haujlwm ua haujlwm thiab saib xyuas. Txawm hais tias feem ntau cov tshuab fais fab muaj cov phiaj xwm hloov pauv thiab txhim kho, lawv feem ntau tsis tuaj yeem siv lawv vim muaj nyiaj tsawg. Rau cov chaw hloov pauv uas muaj nyiaj tsawg, qhov kev daws teeb meem zoo tshaj plaws yog txuas cov khoom siv uas twb muaj lawm rau IEC 61850 network, uas tuaj yeem txo qhov kev nqis peev uas xav tau.
Cov tshuab fais fab uas twb muaj lawm uas tau ua haujlwm tau ntau xyoo lawm tau teeb tsa ntau lub cuab yeej raws li cov txheej txheem sib txuas lus tshwj xeeb, thiab hloov tag nrho lawv ib zaug tsis yog qhov kev xaiv pheej yig tshaj plaws. Yog tias koj xav hloov kho lub tshuab hluav taws xob automation thiab siv lub tshuab SCADA niaj hnub Ethernet los saib xyuas cov khoom siv hauv thaj chaw, yuav ua li cas kom ua tiav tus nqi qis tshaj plaws thiab cov neeg siv khoom tsawg tshaj plaws yog qhov tseem ceeb. Siv cov kev daws teeb meem sib txuas xws li cov servers ntaus ntawv serial, koj tuaj yeem tsim kom muaj kev sib txuas pob tshab ntawm koj lub tshuab SCADA IEC 61850 thiab koj cov khoom siv hauv thaj chaw raws li cov txheej txheem tshwj xeeb. Cov ntaub ntawv protocol tshwj xeeb ntawm cov khoom siv hauv thaj chaw tau ntim rau hauv cov ntaub ntawv Ethernet, thiab lub tshuab SCADA tuaj yeem paub txog kev saib xyuas lub sijhawm tiag tiag ntawm cov khoom siv hauv thaj chaw no los ntawm kev qhib.
Moxa's MGate 5119 Series substation-grade power gateways yooj yim siv thiab tsim kev sib txuas lus zoo sai. Cov series ntawm gateways no tsis yog tsuas yog pab kom muaj kev sib txuas lus sai ntawm Modbus, DNP3, IEC 60870-5-101, IEC 60870-5-104 khoom siv thiab IEC 61850 kev sib txuas lus network, tab sis kuj txhawb nqa NTP lub sijhawm synchronization function kom ntseeg tau tias cov ntaub ntawv muaj lub sijhawm sib koom ua ke. MGate 5119 series kuj muaj lub tshuab tsim cov ntaub ntawv SCL uas ua tiav, uas yooj yim rau kev tsim cov ntaub ntawv SCL ntawm substation gateway, thiab koj tsis tas yuav siv sijhawm thiab nyiaj txiag los nrhiav lwm yam cuab yeej.
Rau kev saib xyuas lub sijhawm tiag tiag ntawm cov khoom siv hauv thaj chaw siv cov txheej txheem tshwj xeeb, Moxa's NPort S9000 series serial device servers kuj tseem tuaj yeem xa mus rau txuas serial IEDs rau Ethernet-based infrastructure los txhim kho cov chaw hloov pauv ib txwm muaj. Cov koob no txhawb nqa txog li 16 lub chaw nres nkoj serial thiab 4 Ethernet switching ports, uas tuaj yeem ntim cov ntaub ntawv protocol tshwj xeeb rau hauv Ethernet packets, thiab yooj yim txuas cov khoom siv hauv thaj chaw rau SCADA systems. Tsis tas li ntawd, NPort S9000 series txhawb nqa NTP, SNTP, IEEE 1588v2 PTP, thiab IRIG-B lub sijhawm sib dhos ua haujlwm, uas tuaj yeem sib dhos tus kheej thiab sib dhos cov khoom siv hauv thaj chaw uas twb muaj lawm.
Thaum koj txhim kho koj txoj kev saib xyuas thiab tswj hwm lub network substation, koj yuav tsum txhim kho kev ruaj ntseg ntawm cov khoom siv network. Moxa cov servers networking thiab protocol gateways yog cov neeg pab zoo los daws cov teeb meem kev ruaj ntseg, pab koj daws ntau yam kev phom sij zais cia los ntawm kev sib txuas lus ntawm cov khoom siv hauv thaj chaw. Ob lub cuab yeej ua raws li IEC 62443 thiab NERC CIP cov qauv, thiab muaj ntau yam kev ruaj ntseg ua ke los tiv thaiv cov khoom siv sib txuas lus los ntawm kev ntsuas xws li kev lees paub tus neeg siv, teeb tsa daim ntawv teev npe IP uas tso cai nkag mus, kev teeb tsa khoom siv thiab kev tswj hwm raws li HTTPS thiab TLS v1.2 protocol kev ruaj ntseg los ntawm kev nkag mus tsis raug cai. Moxa txoj kev daws teeb meem kuj tseem ua qhov kev tshuaj xyuas qhov tsis muaj zog ntawm kev ruaj ntseg thiab siv cov kev ntsuas tsim nyog raws sijhawm los txhim kho kev ruaj ntseg ntawm cov khoom siv network substation hauv daim ntawv ntawm cov ntawv kho kom ruaj ntseg.
Tsis tas li ntawd xwb, Moxa cov serial device servers thiab protocol gateways ua raws li IEC 61850-3 thiab IEEE 1613 cov qauv, ua kom lub network ua haujlwm ruaj khov yam tsis raug cuam tshuam los ntawm qhov chaw nyob ib puag ncig hnyav ntawm cov chaw hloov hluav taws xob.
