Pamene mafunde a Industry 4.0 ndi Industrial Internet of Things (IIoT) akufalikira padziko lonse lapansi, kugwirizana kwa Operational Technology (OT) ndi Information Technology (IT) sikungatheke. Ngakhale kugwirizana kumeneku kumabweretsa zokolola zambiri komanso chidziwitso cha deta, kumaphwanyanso nthano ya "kudzipatula" kwa Industrial Control Systems (ICS), kuwonetsa maukonde ofunikira opanga zinthu ku ziwopsezo zovuta kwambiri pa intaneti.
Monga mtsogoleri wazaka zana limodzi pa njira zothetsera ma signal ndi ma netiweki a mafakitale, Belden akukhulupirira kuti yankho lofunikira pa vutoli si "kukonza" dongosololi pambuyo pomanga, koma kubwerera ku mfundo zoyambira - kukhazikitsa mfundo zachitetezo kuyambira pachiyambi cha kapangidwe ka zomangamanga, kumanga chitetezo cholimba chokhala ndi mphamvu zodzitetezera.
Mavuto Apadera a Chitetezo cha OT: Chifukwa Chiyani Njira Zachitetezo cha IT Sizingasinthidwe Mwachindunji?
Tisanakambirane za mayankho, tiyenera kuzindikira bwino kusiyana kwa chilengedwe cha OT. Mosiyana ndi malo a IT omwe amaika patsogolo "chinsinsi" cha deta, zofunikira zazikulu za chilengedwe cha OT ndi "kupezeka" kwa kupanga ndi "kupitiriza." Nthawi iliyonse yopuma yomwe imabwera chifukwa cha njira zosakwanira zachitetezo ingayambitse kutayika kwachuma kapena ngozi zachitetezo.
Ma network a OT amakumana ndi mavuto apadera:
Kupezeka n'kofunika kwambiri: Zosintha zachitetezo kapena kusanthula sikuyenera kusokoneza njira zopangira.
Machitidwe akale odziwika: Zipangizo zambiri zakale (PLCs, HMIs) sizimathandizira njira zamakono zobisa ma protocol ndipo sizingasinthidwe.
Ma protocol a eni ake: Ma protocol a mafakitale (monga Modbus TCP, EtherCAT, EtherNet/IP, PROFINET) sanapangidwe ndi cholinga cha chitetezo ndipo ali pachiwopsezo choukiridwa.
Malo ovuta: Zipangizo ziyenera kugwira ntchito bwino kutentha kwambiri, chinyezi, komanso kugwedezeka.
Chifukwa chake, kungobwereza njira zachitetezo cha IT m'munda wa OT sikuthandiza. Mayankho achitetezo ayenera kusinthidwa mozama kuti agwirizane ndi zosowa za OT.
Belden Hirschmann: Kumanga Zomangamanga Zachitetezo kuchokera ku Zitatu
Gawo 1: Magawo ndi Ma Conduits - Kupatula Ma Network Olimba
Iyi ndi mfundo yaikulu ya chitetezo cha maukonde a mafakitale. Mwa kugawa maukonde m'malo osiyanasiyana achitetezo (Magawo), monga madera owongolera, madera owunikira, ndi madera opangira zinthu, ndikuletsa kulumikizana pakati pa madera kupita ku ma conduits omveka bwino, kuyenda kwa ziwopsezo kumbali kumatha kuchepetsedwa bwino. Ngakhale madera atakhala pachiwopsezo, kuwonongeka kumatha kuchepetsedwa pang'ono. Belden's Practice: Belden'sHirschmannMndandanda wa ma switch a mafakitale umapereka maziko olimba komanso odalirika a zida zopangira chitsanzo chomveka bwino cha "magawo ndi ma conduits" kudzera mu magawo amphamvu a VLAN (Virtual Local Area Network), Access Control Lists (ACLs), ndi kasamalidwe ka madoko ozungulira. Zimaonetsetsa kuti magalimoto ovomerezeka okha ndi omwe angayende pakati pa madera amitundu yosiyanasiyana yachitetezo.
Gawo 2: Chitetezo cha Malire – "Oyang'anira Zipata Anzeru"
Pambuyo pogawa netiweki m'magawo, malire a gawo lililonse amafunikira "mlonda wapachipata" wamphamvu kuti achite macheke achitetezo okhwima. Izi sizongoletsa magalimoto okha, koma zimafuna chitetezo chanzeru chomwe chimamvetsetsa chilankhulo cha mafakitale. Belden's Practice: Ma firewall achitetezo cha mafakitale a Eagle ndi maziko a gawoli. Si firewall yokha; ndi katswiri wa Deep Packet Inspection (DPI) wopangidwira makamaka malo a OT. Imatha "kumvetsa" ma protocol amakampani monga Modbus TCP, EtherNet/IP, ndi OPC, zomwe zimangolola malamulo ovomerezeka omwe amatsatira malamulo okonzedweratu, pomwe akukana ma paketi aliwonse olamula osazolowereka kapena oyipa, kupereka chitetezo kwa ma PLC omwe ali pachiwopsezo omwe sangasinthidwe.
Gawo lachitatu: Kulimba kwa Netiweki ndi Kuwonekera–
Kuonetsetsa Kuti Ntchito Ikugwira Ntchito Mosalekeza Ndi Kuyankha Mwachangu Maziko a chitetezo ndi kukhazikika. Netiweki yomwe nthawi zambiri imasiya kugwira ntchito bwino ndiyo yokha yomwe ili pachiwopsezo chachikulu cha chitetezo. Kuphatikiza apo, simungathe kuteteza zomwe simukuziwona. Kumvetsetsa bwino netiweki yonse ndikofunikira kuti muteteze mwachangu komanso kuti muyankhe mwachangu.
Machitidwe a Belden: Kulimba kwa Zipangizo Zamagetsi: Zingwe, zolumikizira, ndi ma switch a mafakitale a Belden adapangidwira malo ovuta a mafakitale, omwe ali ndi kukana kwakukulu ku kusokonezedwa ndi maginito amagetsi, kutentha kwakukulu kogwirira ntchito, komanso kudalirika kwambiri, kuonetsetsa kuti kulumikizana kwa netiweki kulipo pamlingo weniweni.
Kuwoneka kwa Netiweki:HirschmannPulogalamu yoyang'anira maukonde a Industrial HiVision imatha kuzindikira zokha zida zonse zomwe zili mu netiweki, zomwe zimakupatsani mwayi wowonera topology ya netiweki ndi momwe thanzi lilili. Dongosololi lidzapereka chenjezo nthawi yomweyo ngati chipangizocho chalephera kulowa kapena kulumikizana kwalephera, zomwe zimalola oyang'anira maukonde kumvetsetsa zomwe zikuchitika ndikuyankha mwachangu.
Chitetezo chapangidwa mwadongosolo, osati chowonjezera. Chitetezo cha maukonde a mafakitale ndi nkhondo yanthawi yayitali; palibe njira yabwino. Komabe, netiweki yokhala ndi kapangidwe ka chitetezo komwe kamayikidwa pamlingo wa zomangamanga idzakhala yolimba kwambiri ku zoopsa kuposa makina omwe amadalira mapulogalamu owonjezera chitetezo.
Malingaliro a Belden ndi omveka bwino komanso osasinthika: chitetezo sichiyenera kukhala lingaliro lokwera mtengo, koma chinthu chofunikira kwambiri pa netiweki. Mwa kuphatikiza mfundo monga kudzipatula kwa malo, chitetezo cha perimeter, kulimba kwa netiweki, ndi kuwonekera kwathunthu mu gawo lililonse lofunikira - ma switch, zipata, zingwe, ndi mapulogalamu oyang'anira - titha kupanga chitetezo champhamvu kwa makasitomala athu chomwe chingapirire zoopsa zakunja ndikuwonetsetsa kuti ntchito zopanga mkati mwa kampani zikuyenda bwino, motero zimawathandiza kuti azitha kuyenda bwino mu kusintha kwa digito mokhazikika komanso mosalekeza.
