Pa makina amagetsi, kuyang'anira nthawi yeniyeni ndikofunikira kwambiri. Komabe, popeza magwiridwe antchito a makina amagetsi amadalira zida zambiri zomwe zilipo, kuyang'anira nthawi yeniyeni kumakhala kovuta kwambiri kwa ogwira ntchito ndi kukonza. Ngakhale makina ambiri amagetsi ali ndi mapulani osinthira ndikusintha, nthawi zambiri sangathe kuwagwiritsa ntchito chifukwa cha bajeti yochepa. Pa malo osinthira omwe ali ndi bajeti yochepa, yankho labwino ndikulumikiza zomangamanga zomwe zilipo ndi netiweki ya IEC 61850, zomwe zingachepetse kwambiri ndalama zomwe zimafunika.
Makina amphamvu omwe alipo omwe akhala akugwira ntchito kwa zaka zambiri ayika zida zambiri kutengera njira zolumikizirana, ndipo kusintha zonse nthawi imodzi si njira yotsika mtengo kwambiri. Ngati mukufuna kukweza makina oyendetsera magetsi ndikugwiritsa ntchito makina amakono a SCADA ozikidwa pa Ethernet kuti muwone zida zam'munda, momwe mungapezere ndalama zochepa komanso kugwiritsa ntchito anthu ochepa ndiye chinsinsi. Pogwiritsa ntchito njira zolumikizirana monga ma seva azipangizo zotsatizana, mutha kukhazikitsa mosavuta kulumikizana kowonekera pakati pa makina anu a IEC 61850 ozikidwa pa mphamvu ya SCADA ndi zida zanu zam'munda zozikidwa pa protocol. Deta ya protocol yazipangizo zam'munda imayikidwa mu mapaketi a data a Ethernet, ndipo makina a SCADA amatha kuyang'anira zida zam'munda nthawi yeniyeni potsegula.
Zipata zamagetsi za Moxa's MGate 5119 Series substation-grade ndizosavuta kugwiritsa ntchito ndipo zimakhazikitsa kulumikizana kosalala mwachangu. Zipata izi sizimangothandiza kulumikizana mwachangu pakati pa zida za Modbus, DNP3, IEC 60870-5-101, IEC 60870-5-104 ndi netiweki yolumikizirana ya IEC 61850, komanso zimathandizira ntchito yolumikizirana nthawi ya NTP kuti zitsimikizire kuti deta ili ndi nthawi yogwirizana. MGate 5119 series ilinso ndi jenereta ya mafayilo a SCL yomangidwa mkati, yomwe ndi yosavuta kupanga mafayilo a substation gateway SCL, ndipo simuyenera kuwononga nthawi ndi ndalama kuti mupeze zida zina.
Kuti zigwiritsidwe ntchito nthawi yeniyeni poyang'anira zida za m'munda pogwiritsa ntchito ma protocol a eni ake, ma seva a chipangizo cha Moxa's NPort S9000 series angagwiritsidwenso ntchito kulumikiza ma IED a serial ku zomangamanga zochokera ku Ethernet kuti akonze malo osinthira achikhalidwe. Mndandanda uwu umathandizira ma serial ports 16 ndi ma Ethernet switching ports anayi, omwe amatha kulongedza deta ya protocol ya eni ake mu mapaketi a Ethernet, ndikulumikiza mosavuta zida za m'munda ku machitidwe a SCADA. Kuphatikiza apo, mndandanda wa NPort S9000 umathandizira ntchito za NTP, SNTP, IEEE 1588v2 PTP, ndi IRIG-B time synchronist, zomwe zimatha kudzigwirizanitsa ndikugwirizanitsa zida za m'munda zomwe zilipo.
Pamene mukulimbitsa netiweki yanu yowunikira ndikuwongolera ma substation, muyenera kukonza chitetezo cha zida za netiweki. Ma seva olumikizirana a zida za Moxa ndi zipata za protocol ndi othandizira oyenera kuthana ndi mavuto achitetezo, kukuthandizani kuthetsa zoopsa zosiyanasiyana zobisika zomwe zimayambitsidwa ndi ma network a zida zam'munda. Zipangizo zonsezi zimagwirizana ndi miyezo ya IEC 62443 ndi NERC CIP, ndipo zimakhala ndi ntchito zambiri zachitetezo zomwe zimamangidwa mkati kuti ziteteze zida zolumikizirana mokwanira kudzera munjira monga kutsimikizira kwa ogwiritsa ntchito, kukhazikitsa mndandanda wa IP wololedwa kulowa, kasinthidwe ka chipangizo ndi kasamalidwe kutengera chitetezo cha protocol cha HTTPS ndi TLS v1.2 kuchokera ku mwayi wosaloledwa. Yankho la Moxa nthawi zonse limachitanso ma scan ofooka achitetezo ndipo limatenga njira zofunikira munthawi yake kuti liwongolere chitetezo cha zida za netiweki za substation mu mawonekedwe a ma patch achitetezo.
Kuphatikiza apo, ma seva a chipangizo cha Moxa ndi zipata za protocol zimagwirizana ndi miyezo ya IEC 61850-3 ndi IEEE 1613, zomwe zimapangitsa kuti netiweki igwire bwino ntchito popanda kukhudzidwa ndi malo ovuta a malo osinthira magetsi.
