Kuri sisitemu yingufu, gukurikirana-igihe ni ngombwa. Ariko, kubera ko imikorere ya sisitemu yamashanyarazi ishingiye kumubare munini wibikoresho bihari, kugenzura igihe nyacyo biragoye cyane kubakozi no kubungabunga. Nubwo sisitemu nyinshi zamashanyarazi zifite gahunda zo guhindura no kuzamura gahunda, akenshi ntizishobora kubishyira mubikorwa kubera ingengo yimari idahwitse. Kubisimbuza ingengo yimishinga mike, igisubizo cyiza nuguhuza ibikorwa remezo bihari numuyoboro wa IEC 61850, bishobora kugabanya cyane ishoramari risabwa.
Sisitemu y'amashanyarazi iriho imaze imyaka mirongo ikora yashyizeho ibikoresho byinshi bishingiye kuri protocole y'itumanaho nyirizina, kandi kuyisimbuza icyarimwe ntabwo aribwo buryo buhendutse cyane. Niba ushaka kuzamura sisitemu yo gukoresha amashanyarazi no gukoresha sisitemu igezweho ya Ethernet ishingiye kuri SCADA kugirango ukurikirane ibikoresho byumurima, uburyo bwo kugera kubiciro buke kandi byibuze abantu binjiza nurufunguzo. Ukoresheje ibisubizo bihuza nkibikoresho byuruhererekane rwibikoresho, urashobora gushiraho byoroshye guhuza mucyo hagati ya sisitemu ya IEC 61850 ishingiye kuri sisitemu ya SCADA hamwe nibikoresho byawe bishingiye kuri protocole. Ibyerekeye protocole yihariye yibikoresho byo murwego byapakiwe mumapaki yamakuru ya Ethernet, kandi sisitemu ya SCADA irashobora kumenya igihe nyacyo cyo kugenzura ibyo bikoresho byo murwego rwo gupakurura.
Moxa's MGate 5119 Urukurikirane rwamashanyarazi-urwego rwamashanyarazi rworoshye gukoresha kandi rushyiraho itumanaho ryoroshye. Uru ruhererekane rw'amarembo ntirufasha gusa kumenya itumanaho ryihuse hagati ya Modbus, DNP3, IEC 60870-5-101, ibikoresho bya IEC 60870-5-104 hamwe numuyoboro witumanaho wa IEC 61850, ariko kandi ushyigikira imikorere ya NTP igihe cyo guhuza kugirango amakuru afite igihe kimwe kashe. MGate 5119 ikurikirana kandi yubatswe muri generator ya dosiye ya SCL, yorohereza kubyara amarembo ya SCL amarembo ya SCL, kandi ntukeneye gukoresha igihe n'amafaranga kugirango ubone ibindi bikoresho.
Kugirango ukurikirane igihe nyacyo ibikoresho byumurima ukoresheje protocole yihariye, seriveri ya seriveri ya NPort S9000 ya Moxa nayo irashobora koherezwa guhuza IED ikurikirana nibikorwa remezo bishingiye kuri Ethernet kugirango izamure insimburangingo gakondo. Uru ruhererekane rushyigikira ibyambu bigera kuri 16 hamwe n’ibyambu 4 byo guhinduranya Ethernet, bishobora gupakira amakuru ya porotokole yihariye mu bikoresho bya Ethernet, kandi bigahuza byoroshye ibikoresho byo mu murima na sisitemu ya SCADA. Mubyongeyeho, urukurikirane rwa NPort S9000 rushyigikira NTP, SNTP, IEEE 1588v2 PTP, na IRIG-B igihe cyo guhuza ibikorwa, gishobora kwikora-guhuza no guhuza ibikoresho bihari byo murwego.
Mugihe ushimangira kugenzura no kugenzura imiyoboro isimbuza, ugomba kunoza umutekano wibikoresho byurusobe. Ibikoresho bya seriveri bya Moxa bihuza seriveri hamwe na amarembo ya protocole nabafasha gusa kugirango bakemure ibibazo byumutekano, bigufasha gukemura ibyago bitandukanye byihishe biterwa no guhuza ibikoresho byumurima. Ibyo bikoresho byombi byujuje ubuziranenge bwa IEC 62443 na NERC CIP, kandi bifite ibikorwa byinshi byubatswe mu mutekano byo kurinda byimazeyo ibikoresho byitumanaho binyuze mu ngamba nko kwemeza abakoresha, gushyiraho urutonde rwa IP rwemerewe kugera, iboneza ry’ibikoresho n’ubuyobozi bishingiye kuri HTTPS na TLS v1. Umutekano wa protocole 2 uhereye kuburenganzira butemewe. Igisubizo cya Moxa nacyo gikora buri gihe isuzuma ry’umutekano muke kandi kigafata ingamba zikenewe mugihe gikwiye kugirango umutekano wibikoresho byumuyoboro wogusimbuza muburyo bwumutekano.
Byongeye kandi, seriveri ya seriveri ya seriveri ya Moxa hamwe n’amarembo ya protocole yubahiriza ibipimo bya IEC 61850-3 na IEEE 1613, bigatuma imikorere y'urusobekerane rudahungabana itabangamiwe n’ibidukikije bikaze bya sitasiyo.
