Kwiinkqubo zamandla, ukubeka iliso ngexesha lokwenyani kubalulekile.Nangona kunjalo, ekubeni ukusebenza kwenkqubo yamandla kuxhomekeke kwinani elikhulu lezixhobo ezikhoyo, ukubeka iliso ngexesha lokwenyani kulucelomngeni olukhulu ekusebenzeni nasekulondolozweni kwabasebenzi.Nangona uninzi lweenkqubo zamandla zinezicwangciso zenguqu kunye nokuphucula, zihlala zingakwazi ukuziphumeza ngenxa yohlahlo lwabiwo-mali olungqongqo.Ukufumana i-substations kunye nohlahlo lwabiwo-mali olulinganiselwe, isisombululo esifanelekileyo kukudibanisa iziseko ezikhoyo kwinethiwekhi ye-IEC 61850, enokunciphisa kakhulu utyalo-mali olufunekayo.
Iisistim zamandla ezikhoyo ezisebenza kangangamashumi eminyaka zifakele izixhobo ezininzi ezisekelwe kwiiprothokholi zonxibelelwano lobunikazi, kwaye ukuzitshintsha zonke ngaxeshanye asilokhetho olungabizi kakhulu.Ukuba ufuna ukuphucula inkqubo ye-automation system kwaye usebenzise inkqubo ye-SCADA esekelwe kwi-Ethernet yanamhlanje ukujonga izixhobo zentsimi, indlela yokufikelela kwindleko ephantsi kunye neyona nto encinci igalelo lomntu ngundoqo.Ukusebenzisa izisombululo zoqhagamshelwano ezifana neeseva zesixhobo sothotho, unokuseka ngokulula unxibelelwano olucacileyo phakathi kwenkqubo yakho ye-SCADA esekwe kwi-IEC 61850 yamandla kunye nezixhobo zakho ezisekelwe kwiprotocol esekwe kwintsimi.Idatha yeprotocol yobunikazi yezixhobo zentsimi zipakishwe kwiipakethi zedatha ye-Ethernet, kwaye inkqubo ye-SCADA inokuqonda ukubeka iliso ngexesha langempela kwezi zixhobo zentsimi ngokukhupha.
I-Moxa's MGate 5119 Series yamasango ombane akwinqanaba elisezantsi kulula ukuyisebenzisa kwaye ikhawuleze iseke unxibelelwano olugudileyo.Olu chungechunge lwamasango aluncedi nje ukuqonda unxibelelwano olukhawulezayo phakathi kwe-Modbus, i-DNP3, i-IEC 60870-5-101, izixhobo ze-IEC 60870-5-104 kunye ne-IEC 61850 inethiwekhi yonxibelelwano, kodwa ixhasa umsebenzi wokuvumelanisa ixesha le-NTP ukuqinisekisa ukuba idatha inexesha elidibeneyo. isitampu .Uthotho lwe-MGate 5119 lukwanalo nejenereyitha yefayile ye-SCL eyakhelwe-ngaphakathi, elungele ukuvelisa iifayile ze-SCL zesango lesikhululo, kwaye akukho mfuneko yokuba uchithe ixesha kunye nemali ukuze ufumane ezinye izixhobo.
Ukujongwa kwexesha lokwenyani lezixhobo zentsimi kusetyenziswa iiprothokholi zobunikazi, i-Moxa's NPort S9000 iiseva zesixhobo se-serial nazo zingasetyenziselwa ukudibanisa ii-IED ze-serial kwiziseko ezisekelwe kwi-Ethernet ukuphucula izitishi zemveli.Olu chungechunge luxhasa ukuya kuthi ga kwi-16 izibuko ze-serial kunye ne-4 Ethernet yokutshintsha izibuko, ezinokupakisha idatha yeprotocol yobunikazi kwiipakethi ze-Ethernet, kwaye zidibanise ngokulula izixhobo zentsimi kwiinkqubo ze-SCADA.Ukongeza, uchungechunge lwe-NPort S9000 luxhasa i-NTP, i-SNTP, i-IEEE 1588v2 PTP, kunye ne-IRIG-B imisebenzi yongqamaniso lwexesha, enokuthi ikwazi ukuzilungelelanisa kunye nokulungelelanisa izixhobo ezikhoyo zentsimi.
Njengoko uqinisa esweni kunye nokulawula inethiwekhi yesitishi esincinci, kufuneka uphucule ukhuseleko lwesixhobo sothungelwano.Iiseva zenethiwekhi zothungelwano zesixhobo se-Moxa kunye namasango eprothokholi ngabancedi abafanelekileyo ukujongana nemiba yokhuseleko, ukunceda ukusombulula iingozi ezahlukeneyo ezifihliweyo ezibangelwa kuthungelwano lwesixhobo sentsimi.Zombini izixhobo zihambelana nemigangatho ye-IEC 62443 kunye ne-NERC CIP, kwaye zinemisebenzi emininzi yokhuseleko eyakhelwe-ngaphakathi ukukhusela ngokubanzi izixhobo zonxibelelwano ngemilinganiselo efana nokuqinisekiswa komsebenzisi, ukuseta uluhlu lwe-IP oluvunyelwe ukufikelela, ukucwangciswa kwesixhobo kunye nolawulo olusekelwe kwi-HTTPS kunye ne-TLS v1. 2 ukhuseleko lweprotocol ukusuka ekufikeleleni okungagunyaziswanga.Isisombululo se-Moxa siphinda senza rhoqo ukuskena komngcipheko wokhuseleko kwaye sithatha amanyathelo ayimfuneko ngexesha elifanelekileyo lokuphucula ukhuseleko lwezixhobo zenethiwekhi ye-substation ngendlela yeepatches zokhuseleko.
Ukongezelela, iiseva ze-serial device ze-Moxa kunye namasango eprotocol zihambelana ne-IEC 61850-3 kunye nemigangatho ye-IEEE 1613, iqinisekisa ukusebenza kwenethiwekhi ezinzileyo ngaphandle kokuchatshazelwa yimeko enzima ye-substations.
