Ngezinhlelo zamandla, ukuqapha isikhathi sangempela kubalulekile. Kodwa-ke, njengoba ukusebenza kohlelo lwamandla kuncike enanini elikhulu lemishini ekhona, ukuqapha isikhathi sangempela kuyinselele kakhulu kubasebenzi abasebenza kanye nokunakekela. Yize amasistimu amaningi anamandla anenguquko nezinhlelo zokuthuthukisa, zivame ukungakwazi ukuzisebenzisa ngenxa yezabelomali eziqinile. Okokufakazelwa kwesabelomali esilinganiselwe, isisombululo esifanelekile ukuxhuma ingqalasizinda ekhona kwinethiwekhi ye-IEC 61850, enganciphisa kakhulu ukutshalwa kwemali okudingekayo.
Izinhlelo ezikhona zamandla ezisetshenzisiwe zamashumi eminyaka zifake amadivaysi amaningi ngokususelwa ezinkonzweni zokuxhumana zokuxhumana, futhi zikubuyise zonke izinketho ezingezenzeki kakhulu. Uma ufuna ukuthuthukisa uhlelo lwe-automation yamandla futhi usebenzise uhlelo lwesimanje lwe-Ethernet-based Scada ukuqapha amadivayisi wensimu, ukuthi ungafinyelela kanjani izindleko eziphansi kakhulu futhi okuphansi kokungumuntu kungukhiye. Usebenzisa izixazululo zokuxhumana ezinjengeseva yedivaysi eqondile, ungasungula kalula ukuxhumana okusobala phakathi kohlelo lwakho lwe-IEC 61850 olususelwa ku-Scada yamadivayisi wenkambu ye-Protocol esekwe. Idatha yephrothokholi yokuphathelene yamadivayisi wensimu ifakwe emaphaketheni wedatha ye-Ethernet, futhi uhlelo lwe-scada luyakwazi ukuqaphela kwangempela kwalawa madivayisi wensimu ngokuvula.
I-MGate's MGate 5119 Uchungechunge lwe-Expase-grade Amatende Amandla Amateaway kulula ukuyisebenzisa futhi ngokushesha asungule ukuxhumana okubushelelezi. Lolu chungechunge lwamasango alusizi kuphela ukubona ukuxhumana okusheshayo phakathi kwe-Modbus, i-DNP3, i-IEC 60870-5-1050, kepha futhi isekela i-NTPIME Synchronication Network ukuze uqinisekise ukuthi idatha inesitembu sesikhathi esibumbene. I-MGate 5119 Series ibuye ibe ne-generator yefayela le-SCL eyakhelwe ngaphakathi, okulungele ukukhiqiza amafayela aphezulu wesango le-SCL, futhi awudingi ukuchitha isikhathi nemali ukuthola amanye amathuluzi.
Ngokuqapha kwangempela kwamadivayisi wensimu kusetshenziswa amaphrothokholi okuphathelene, amaseva we-M9000 e-NOPPA's errial amaseva angahle athunyelwe ukuxhumanisa i-IEDS ye-Ethernet ukuthuthukisa izingane zendabuko. Lolu chungechunge luxhasa amachweba afinyelela kwa-16 ngokulandela kanye namachweba ama-4 ethernet ashintsha, angapakisha idatha yephrothokholi ephathelene namaphakethe we-Ethernet, futhi axhuma kalula amadivayisi wensimu ezinhlelweni zeScada. Ngaphezu kwalokho, uchungechunge lwe-NOPT S9000 lusekela i-NTP, i-SNTP, i-158VV2 PTP, kanye nemisebenzi yokuvumelanisa yesikhathi se-Irig-B, engavumelanisa nokuvumelanisa amadivayisi wensimu akhona.
Njengoba uqinisa ukuqapha kwakho nokulawula inethiwekhi yokufaka esikhundleni, kufanele uthuthukise ukuphepha kwedivayisi yenethiwekhi. Amaseva we-Serial Difports we-Serial Difports kanye ne-Protocol Gateways angabasizi abalungile nje ukubhekana nezinkinga zokuphepha, bakusize ukuxazulula izingozi ezahlukahlukene ezicashile ezibangelwa ukuxhumeka kwensiza yasensimini. Womabili amadivaysi ahambisana namazinga we-IEC 62443 nama-NECREL CRESS, futhi abe nemisebenzi eminingi yokuphepha eyakhelwe ngaphakathi ekuvikelekeni okuphelele kwezinyathelo ezinjengokuqinisekiswa komsebenzisi, ukucushwa kwensiza okusekelwe ekuvikelekeni kwe-HTTPS kanye ne-TLS V1.2 Ukuphepha kwe-Protocol kusuka ekufinyelelekeni okungagunyaziwe. Isixazululo sikaMoxa futhi senza njalo ukuskena ubungozi bokuphepha futhi kuthatha izindlela ezidingekayo ngesikhathi esifanele sokuthuthukisa ukuphepha kwemishini yenethiwekhi yokuphepha ngendlela yezokuphepha.
Ngaphezu kwalokho, amaseva we-serial wedivaysi e-Moxa kanye nama-protocol amasango ahambisana ne-IEC 61850-3 futhi amazinga angu-1613, aqinisekisa ukusebenza kwenethiwekhi ngaphandle kokuthi athintwe yindawo enokhahlo.
