Ku bijyanye n'amashanyarazi, kugenzura mu buryo bufatika ni ingenzi cyane. Ariko, kubera ko imikorere y'amashanyarazi ishingiye ku bikoresho byinshi bihari, gukurikirana mu buryo bufatika ni imbogamizi ikomeye ku bakozi bakora n'ababungabunga amashanyarazi. Nubwo amashanyarazi menshi afite gahunda zo guhindura no kuvugurura amashanyarazi, akenshi ntashobora kuyashyira mu bikorwa bitewe n'ingengo y'imari nto. Ku mashanyarazi afite ingengo y'imari nto, igisubizo cyiza ni uguhuza ibikorwa remezo bihari n'umuyoboro wa IEC 61850, bishobora kugabanya cyane ishoramari rikenewe.
Sisitemu z'amashanyarazi zisanzweho zimaze imyaka ibarirwa muri za mirongo zikora zashyizeho ibikoresho byinshi bishingiye kuri protocole z'itumanaho bwite, kandi kuzisimbuza byose icyarimwe si bwo buryo buhendutse cyane. Niba ushaka kuvugurura sisitemu y'amashanyarazi ikoresha ikoranabuhanga rigezweho rya SCADA ikoresha Ethernet kugira ngo ukurikirane ibikoresho byo mu murima, uburyo bwo kugera ku giciro gito cyane n'uburyo bworoshye bwo kwinjiza ni ingenzi. Ukoresheje ibisubizo byo guhuza nka seriveri z'ibikoresho bya serial, ushobora gushyiraho byoroshye isano igaragara hagati ya sisitemu yawe ya SCADA ikoresha amashanyarazi ya IEC 61850 n'ibikoresho byawe byo mu murima bishingiye kuri protocole. Amakuru ya protocole y'ibikoresho byo mu murima ashyirwa mu mapaki ya data ya Ethernet, kandi sisitemu ya SCADA ishobora gukurikirana ibyo bikoresho byo mu murima mu buryo bwihuse binyuze mu kubipakurura.
Inzira z'amashanyarazi zo mu bwoko bwa Moxa za MGate 5119 Series zoroshye gukoresha kandi zituma habaho itumanaho rigenda neza vuba. Uru ruhererekane rw'inzira ntirufasha gusa mu gutumanaho byihuse hagati y'ibikoresho bya Modbus, DNP3, IEC 60870-5-101, IEC 60870-5-104 n'umuyoboro w'itumanaho wa IEC 61850, ahubwo runashyigikira imikorere ya NTP yo guhuza igihe kugira ngo amakuru abe afite ikimenyetso cy'igihe kimwe. Inzira ya MGate 5119 ifite kandi icyuma gitanga dosiye za SCL, cyoroshye gukora dosiye za SCL zo mu bwoko bwa substation, kandi ntukeneye gukoresha umwanya n'amafaranga kugira ngo ushake ibindi bikoresho.
Kugira ngo habeho igenzura ry’ibikoresho byo mu kibuga mu buryo bwihuse hakoreshejwe protocole za nyirabyo, seriveri za Moxa za NPort S9000 series device serial zishobora no gushyirwa mu guhuza serial IEDs n’ibikorwa remezo bishingiye kuri Ethernet kugira ngo havugururwe substations zisanzwe. Uru rukurikirane rushyigikira serial ports zigera kuri 16 na Ethernet switching ports 4, zishobora gushyira amakuru ya protocole muri paki za Ethernet, kandi zigahuza byoroshye ibikoresho byo mu kibuga na sisitemu za SCADA. Byongeye kandi, NPort S9000 series ishyigikira imikorere ya NTP, SNTP, IEEE 1588v2 PTP, na IRIG-B time synchronize, zishobora kwihuza no guhuza ibikoresho byo mu kibuga bisanzwe.
Uko ukomeza umuyoboro wawe wo kugenzura no kugenzura imiyoboro ya sitasiyo, ugomba kunoza umutekano w'ibikoresho bya interineti. Seriveri za Moxa zo guhuza ibikoresho na porogaramu ni zo zigufasha gukemura ibibazo by'umutekano, zigufasha gukemura ibibazo bitandukanye byihishe biterwa n'imiyoboro ya sitasiyo. Ibikoresho byombi byubahiriza amahame ya IEC 62443 na NERC CIP, kandi bifite imirimo myinshi y'umutekano yo kurinda ibikoresho by'itumanaho binyuze mu ngamba nko kwemeza abakoresha, gushyiraho urutonde rwa IP rwemewe kwinjiramo, imiterere y'ibikoresho no kubicunga hashingiwe ku mutekano wa HTTPS na TLS v1.2 protocol kuva ku bantu batabifitiye uburenganzira. Igisubizo cya Moxa kandi gihora gisuzuma ibibazo by'umutekano kandi gifata ingamba zikenewe ku gihe kugira ngo cyongere umutekano w'ibikoresho bya sitasiyo mu buryo bw'ibikoresho by'umutekano.
Byongeye kandi, seriveri za Moxa zikoresha ibikoresho bya seriveri n'inzira za protocole zujuje ibisabwa na IEC 61850-3 na IEEE 1613, bigamije gutuma imikorere y'umuyoboro ihora ihagaze neza nta ngaruka mbi ziterwa n'ibidukikije bibi bya sitasiyo.
