Kwa machitidwe amagetsi, kuyang'anira nthawi yeniyeni ndikofunikira.Komabe, popeza ntchito yamagetsi imadalira zida zambiri zomwe zilipo, kuyang'anira nthawi yeniyeni ndizovuta kwambiri kwa ogwira ntchito ndi kukonza.Ngakhale machitidwe ambiri amagetsi ali ndi mapulani osintha ndi kukweza, nthawi zambiri amalephera kuwagwiritsa ntchito chifukwa cha bajeti yolimba.Pazigawo zazing'ono zomwe zili ndi bajeti yochepa, njira yabwino ndiyo kulumikiza zida zomwe zilipo ku netiweki ya IEC 61850, yomwe ingachepetse kwambiri ndalama zomwe zimafunikira.
Makina amagetsi omwe alipo omwe akhala akugwira ntchito kwa zaka zambiri ayika zida zambiri potengera njira zolumikizirana ndi eni ake, ndipo kusintha zonse nthawi imodzi si njira yotsika mtengo.Ngati mukufuna kukweza makina opangira mphamvu ndikugwiritsa ntchito makina amakono a Ethernet a SCADA kuti ayang'ane zipangizo zam'munda, momwe mungakwaniritsire mtengo wotsika kwambiri komanso kuyikapo kwa anthu ndikofunika kwambiri.Pogwiritsa ntchito njira zolumikizirana monga maseva a chipangizo cha serial, mutha kukhazikitsa mosavuta kulumikizana kowonekera pakati pa dongosolo lanu la IEC 61850-based power SCADA system ndi zida zanu zakumunda zotengera protocol.Deta ya proprietary protocol ya zida zam'munda zimayikidwa m'mapaketi a data a Ethernet, ndipo dongosolo la SCADA limatha kuzindikira kuwunika kwanthawi yeniyeni kwa zida zam'munda mwa kumasula.
Zipata zamagetsi za Moxa's MGate 5119 Series ndizosavuta kugwiritsa ntchito ndikukhazikitsa kulumikizana kosalala.Mndandanda wa zipatawu sikuti umangothandiza kuzindikira kulumikizana mwachangu pakati pa Modbus, DNP3, IEC 60870-5-101, zida za IEC 60870-5-104 ndi netiweki yolumikizana ya IEC 61850, komanso imathandizira ntchito yolumikizira nthawi ya NTP kuonetsetsa kuti deta ili ndi nthawi yolumikizana. sitampu .Mndandanda wa MGate 5119 ulinso ndi jenereta ya fayilo ya SCL, yomwe ndi yabwino kupanga mafayilo a SCL pachipata cha substation, ndipo simuyenera kuwononga nthawi ndi ndalama kuti mupeze zida zina.
Pakuwunika kwenikweni kwa zida zam'munda pogwiritsa ntchito ma protocol eni ake, ma seva a Moxa's NPort S9000 angapo atha kutumizidwanso kuti alumikizane ndi ma IED amtundu wa Ethernet kuti akweze masiteshoni achikhalidwe.Mndandandawu umathandizira mpaka ma 16 ma serial ports ndi ma 4 Ethernet switching ports, omwe amatha kunyamula deta ya proprietary protocol mu mapaketi a Ethernet, ndikulumikiza mosavuta zida zakumunda ku machitidwe a SCADA.Kuphatikiza apo, mndandanda wa NPort S9000 umathandizira NTP, SNTP, IEEE 1588v2 PTP, ndi IRIG-B ntchito zolumikizana nthawi, zomwe zimatha kudzigwirizanitsa zokha ndikugwirizanitsa zida zomwe zilipo kale.
Pamene mukulimbitsa kuwunika kwanu ndikuwongolera maukonde a substation, muyenera kukonza chitetezo pazida zama netiweki.Ma seva ochezera pa intaneti a Moxa's serial device ndi zipata za protocol ndi othandiza okhawo kuthana ndi zovuta zachitetezo, kukuthandizani kuthana ndi zoopsa zosiyanasiyana zobisika zomwe zimayambitsidwa ndi intaneti yazida zam'munda.Zida zonsezi zimagwirizana ndi IEC 62443 ndi NERC CIP miyezo, ndipo zimakhala ndi ntchito zambiri zotetezedwa kuti ziteteze bwino zipangizo zoyankhulirana kudzera mumiyeso monga kutsimikizira kwa wogwiritsa ntchito, kukhazikitsa mndandanda wa IP wololedwa kuti upeze, kasinthidwe kachipangizo ndi kasamalidwe kochokera pa HTTPS ndi TLS v1. 2 chitetezo cha protocol kuchokera pakulowa kosaloledwa.Yankho la Moxa limachitanso nthawi zonse kuwunika kwachitetezo chachitetezo ndikuchitapo kanthu munthawi yake kuti apititse patsogolo chitetezo cha zida zapaintaneti za substation ngati zigamba zachitetezo.
Kuphatikiza apo, ma seva a serial device a Moxa ndi zipata za protocol zimagwirizana ndi miyezo ya IEC 61850-3 ndi IEEE 1613, kuwonetsetsa kuti ma netiweki azigwira ntchito mokhazikika popanda kukhudzidwa ndi malo ovuta a malo.
