Mndandanda ndi masiwichi osayendetsedwa amakampani omwe, ngakhale ndi kuphweka kwawo, ali ndi ntchito zingapo zapamwamba. Zosinthazi zimaphatikizidwa mosavuta mudongosolo lililonse la SCADA chifukwa chothandizira ma protocol otseguka a Modbus TCP ndi SNMP, ali ndi chitetezo ku kusintha kolakwika ndikuwonetsa zolakwika pagawo lakutsogolo kuti muchotse mosavuta. Pali chithandizo cha protocol ya IEEE 802.3az, yomwe imachepetsa kugwiritsa ntchito mphamvu mpaka 60%, ndipo kugwira ntchito pa kutentha kwakukulu kuchokera -40 Β° C mpaka 75 Β° C kumapangitsa kuti masinthidwe agwiritsidwe ntchito m'madera ovuta kwambiri.
M'nkhaniyi, timvetsetsa momwe ma switch a mafakitale amasiyanirana ndi ma switch a SOHO apanyumba, yesani ntchito zamafakitale za chipangizocho, ndikuganiziranso njira yokhazikitsira.
Mawonekedwe a Industrial
Kusiyana kwakukulu pakati pa zosintha zamafakitale ndi zapakhomo ndizofunika kwambiri pakudalirika pogwira ntchito zilizonse. Mitundu yamafakitale imakhala ndi chitetezo chambiri, kusintha ntchito zoteteza zolakwika, komanso zida zowongolera zovuta komanso zovuta zosayina. Nyumba zamitundu yamafakitale zidapangidwa kuti zizitha kupirira katundu wamakina ndikukhala ndi njanji yokhazikika ya DIN.
EKI-2000 mndandanda
Mndandanda wa masinthidwewo umapangidwira malo ang'onoang'ono pomwe kukhazikitsa malamulo osinthira ndikugawa maukonde kukhala ma VLAN sikofunikira. Zosinthazi zilibe zoikamo ndipo ndi njira yotsika mtengo kwambiri kuchokera pamzere wosinthira wa EKI.
- imodzi mwazosintha zazing'ono kwambiri padziko lonse lapansi. M'lifupi mwake ndi 2.5 masentimita ndi kutalika kwa 8 masentimita amalola kuti akhazikike mosavuta mu ma switchboards osakanikirana kwambiri, ndipo thupi la chipangizocho limapangidwa ndi zitsulo ndipo lili ndi chitetezo cha IP40. ____________________________________________________________________________________
multifunctional gigabit PoE switch ndi mphamvu yotulutsa mpaka 30W padoko lililonse. Ili ndi ma doko a 4 SFP oyika ma module owoneka. Mtunduwu uli ndi satifiketi yotsata EN50121-4 muyezo waku Europe pakuyika pamayendedwe anjanji. ____________________________________________________________________________________
EKI-5000 mndandanda
Zipangizo za mndandandawu zili ndi zina zowonjezera kuti ziphatikizidwe mu machitidwe a SCADA. Ntchito ya ProView imakupatsani mwayi wowunika momwe doko lililonse liliri pogwiritsa ntchito ma protocol a Modbus ndi SNMP. Zosankha zapamwamba zodzizindikiritsa za chipangizochi zimathandizira kuzindikira zolakwika zosinthira, ndipo chiphaso chachitetezo chamagetsi chimalola kuti kusinthaku kuyikidwe m'malo owopsa.
- Sinthani ndi ma 4 optical ndi Ethernet madoko
Zolemba zamakono
- 4 madoko owoneka
- Kuwunika kudzera pa Modbus TCP ndi SNMP
- Kuthandizira kwa protocol yopulumutsa mphamvu ya Ethernet 802.3az
- Thandizo la chimango cha Jumbo
- Kuyika patsogolo kwa doko la QoS
- Kuzindikira lupu kuti mupewe mkuntho wa ARP
- Lowetsani mphamvu zosunga zobwezeretsera ndi chizindikiro cholephera mphamvu
- Kutentha kumasiyana -40 mpaka 75 Β° C
Kusinthaku kungagwiritsidwe ntchito ngati chosinthira media kuti muphatikize mizere ya kuwala ndi zingwe zopotoka pamasamba akutali. Palinso mitundu yokhala ndi chithandizo cha PoE cholumikizira kuwunika kwamavidiyo ndi makina owonera makina.
Zizindikiro zakutsogolo zikuwonetsa momwe mzere uliwonse wamagetsi ulili
Chitetezo chamagetsi ndi chitetezo chosokoneza
Zosintha za EKI-2000 zokhala ndi chitetezo chokhazikika kuti chisasokonezedwe kwakanthawi kochepa pazingwe zamagetsi mpaka ma volts 3, komanso chitetezo kumagetsi osasunthika pamizere ya Ethernet mpaka 4 volts.
5000 Series ndi ATEX/C1D2/IECEx yotsimikiziridwa ndi kuphulika ndipo ingagwiritsidwe ntchito pophulika ndi mafuta ndi gasi.
Kusunga mphamvu ndi chizindikiro cholakwika
Zida zonse pamndandanda zili ndi zolowetsa mphamvu ziwiri ndikukulolani kuti mulumikize gwero lamagetsi losunga zobwezeretsera, mwachitsanzo kuchokera ku batri. Kukanika mphamvu yayikulu, makinawo amasinthira ku gwero lamagetsi losunga zosunga zobwezeretsera popanda kuyimitsa ntchito, ndipo zowonetsa zolephera zidzagwira ntchito.
Pakachitika kusweka mu imodzi mwa mizere yamagetsi, relay imatsegulidwa
Ethernet 802.3az yogwira ntchito bwino
Muyezo wa IEEE 802.3az, womwe umatchedwanso Green Ethernet, wapangidwa kuti usunge mphamvu, zomwe ndizofunikira kwambiri m'malo omwe amadalira ma solar solar kapena mphamvu zosunga zobwezeretsera. Ukadaulo umangodziwikiratu kutalika kwa kulumikizana kwa zingwe ndikusinthira mphamvu yazizindikiro yopatsirana potengera izi. Chifukwa chake, pamalumikizidwe amfupi mphamvu yotumizira imachepetsedwa poyerekeza ndi mizere yayitali. Madoko osagwiritsidwa ntchito amakhala opanda mphamvu.
Smart PoE
Mitundu yomwe imathandizira PoE (Power over Ethernet) imakupatsani mwayi wowunika ma voliyumu ndi momwe mungagwiritsire ntchito padoko lililonse pogwiritsa ntchito protocol ya Modbus. Pogwiritsa ntchito kuwunika, mutha kuzindikira kusintha kwa katundu wokhazikika ndikuzindikira zolakwika za ogula, mwachitsanzo, kuwunikira kolephera kwa kamera yowonera kanema.
Mafelemu a Jumbo
Zida zonse pamndandanda zimathandizira mafelemu a Jumbo, omwe amakulolani kusamutsa mafelemu a Efaneti mpaka 9216 byte mu kukula, m'malo mwa ma byte 1500. Izi zimakupatsani mwayi wopewa kugawikana mukamasamutsa kuchuluka kwa data ndipo, nthawi zina, kuchepetsa kuchedwetsa kusamutsa deta.
Kuzindikira kwa loop
Masinthidwe okhala ndi loop kuzindikira amangozindikira cholakwika chosinthira pomwe madoko awiri amapanga lupu ndikutseka okha kuti apewe kusokonezeka kwa zida zina zolumikizidwa.
Madoko kumene kuzungulira kumapezeka amalembedwa ndi chizindikiro chapadera kuti athe kupezeka mwachiwonekere. Chitetezo chosavuta komanso chothandizachi chimagwira ntchito popanda protocol ya STP/RSTP.
Chiwonetsero cha ProView-ModBus ndi SNMP
Zosintha za EKI-5000 zimathandizira gawo la ProView, lomwe limawonjezera kuthekera kowunika thanzi la ma switch osayendetsedwa. Ndi chithandizo cha ma protocol otseguka a Modbus TCP ndi SNMP, njirayi imakulolani kuti muphatikize chosinthira mu dongosolo lililonse la SCADA kapena gulu lowunikira maukonde. Chipangizocho chimagwirizana ndi dongosolo la Advantech ndi network management system .
Zomwe zikupezeka kudzera pa SNMP ndi Modbus:
β’ Chitsanzo cha chipangizo ndi kufotokozera kosankha
β’ Mtundu wa firmware
β’ Efaneti MAC
β’ IP adilesi
β’ Ziwerengero zamadoko: mawonekedwe, liwiro, zolakwika
β’ Kuchuluka kwa deta yofalitsidwa ndi madoko
β’ Kufotokozera mwamakonda doko
β’ Kauntala yochotsa madoko
β’ Mkhalidwe wa PoE/kagwiritsidwe kake ndi mphamvu yamagetsi (yamitundu yokhala ndi PoE)
kusintha
Kukonzekera koyamba kungathe kuchitika kudzera .
Kukhazikitsa Adilesi ya IP
Pa System tab, mukhoza kukhazikitsa dzina la chipangizo ndi ndemanga (dzina ili ndi kufotokozera zidzapezeka kudzera pa SNMP ndi Modbus), ikani nthawi yopuma ya mapaketi a modbus, ndikupeza mtundu wa firmware.
Pomaliza
Sinthani mndandanda ndi njira yosavuta komanso nthawi yomweyo yogwira ntchito pamasamba ang'onoang'ono akutali. Chiwonetsero cha gulu lakutsogolo limakupatsani mwayi wozindikira mavuto mwachangu popanda kukhudzidwa ndi ogwira ntchito oyenerera. Kugwiritsa ntchito kutentha kwambiri komanso nyumba zosagwira ntchito zimalola kuti zidazo zizigwiritsidwa ntchito m'malo ovuta.
