Kodi zofunikira zapadera za zingwe za Profinet ndi ziti?

Profinet ndi njira yolumikizirana yamafakitale yochokera ku Ethernet, yomwe imagwiritsidwa ntchito kwambiri mumakina owongolera odziyimira pawokha, zofunikira zapadera za chingwe cha Profinet zimayang'ana kwambiri mawonekedwe akuthupi, magwiridwe antchito amagetsi, kusinthasintha kwa chilengedwe ndi zofunikira pakuyika. Nkhaniyi iyang'ana kwambiri chingwe cha Profinet kuti chiwunikidwe mwatsatanetsatane.

I. Makhalidwe Athupi

1, mtundu wa chingwe

Chipinda Chopindika Chotetezedwa (STP/FTP): Chipinda Chopindika Chotetezedwa chimalimbikitsidwa kuti chichepetse kusokoneza kwa maginito (EMI) ndi kulankhulana mozungulira. Chipinda chopindika chotetezedwa chingalepheretse bwino kusokoneza kwa maginito akunja ndikukweza kukhazikika ndi kudalirika kwa kutumiza kwa maginito.

Unshielded Twisted Pair (UTP): Unshielded Twisted Pair ingagwiritsidwe ntchito m'malo omwe mulibe kusokoneza kwa maginito, koma sikuvomerezeka kugwiritsidwa ntchito m'malo opangira mafakitale.

2, kapangidwe ka chingwe

Mawiri anayi a chingwe chopindika: Chingwe cha Profinet nthawi zambiri chimakhala ndi mawiri anayi a chingwe chopindika, mawaya awiri aliwonse opangidwa ndi mawaya awiri otumizira deta ndi magetsi (ngati pakufunika).

Chipinda cha Waya: Ma waya nthawi zambiri amakhala 22 AWG, 24 AWG, kapena 26 AWG, kutengera mtunda wotumizira ndi mphamvu ya chizindikiro. 24 AWG ndi yoyenera mtunda wautali wotumizira, ndipo 26 AWG ndi yoyenera mtunda waufupi.

3, cholumikizira

Cholumikizira cha RJ45: Zingwe za Profinet zimagwiritsa ntchito zolumikizira za RJ45 kuti zitsimikizire kuti zikugwirizana ndi zipangizo za Profinet.

Njira Yotsekera: Zolumikizira za RJ45 zokhala ndi njira yotsekera zimalimbikitsidwa m'malo opangira mafakitale kuti zipewe kulumikizana kosakhazikika ndikuwonetsetsa kuti kulumikizanako kuli kodalirika.

Chachiwiri, kusinthasintha kwa chilengedwe

1, Kutentha kwapakati

Kapangidwe ka kutentha kwakukulu: Chingwe cha Profinet chiyenera kugwira ntchito bwino pa kutentha kwakukulu, nthawi zambiri chimayenera kupirira kutentha kwa -40 ° C mpaka 70 ° C.

2, Chitetezo cha mlingo

Chitetezo chapamwamba: Sankhani zingwe zokhala ndi chitetezo chapamwamba (monga IP67) kuti fumbi ndi nthunzi yamadzi zisalowe m'malo ovuta a mafakitale.

3, kugwedezeka ndi kukana kugwedezeka

Mphamvu ya makina: Zingwe za Profinet ziyenera kukhala ndi kugwedezeka bwino komanso kukana kugwedezeka, zoyenera kugwedezeka komanso malo ogwedezeka.

4, kukana mankhwala

Kukana mafuta, asidi ndi alkali: Sankhani zingwe zokhala ndi kukana mankhwala monga mafuta, asidi ndi alkali kuti zigwirizane ndi malo osiyanasiyana amafakitale.

III. Zofunikira pa Kukhazikitsa

1, njira yolumikizira mawaya

Pewani kusokoneza magetsi mwamphamvu: mu mawaya muyenera kuyesa kupewa kuyika pamodzi ndi zingwe zamagetsi zamphamvu, ma mota ndi zida zina zamagetsi zolimba kuti muchepetse kusokoneza kwa magetsi.

Kapangidwe koyenera: Kukonzekera bwino njira yolumikizira mawaya, kuti mupewe kupindika kwambiri kapena kukakamiza chingwe, kuti muwonetsetse kuti chingwecho chili bwino.

2, njira yokonza

Bulaketi yokhazikika: Gwiritsani ntchito bulaketi yokhazikika ndi cholumikizira choyenera kuti muwonetsetse kuti chingwecho chakhazikika bwino kuti chisagwedezeke kapena kuyenda komwe kumachitika chifukwa cha kulumikizana kosakhazikika.

Chitoliro cha waya ndi chitoliro: M'malo ovuta, ndi bwino kugwiritsa ntchito chitoliro cha waya kapena chitoliro kuti muteteze chingwe kuti mupewe kuwonongeka kwa makina ndi kuwonongeka kwa chilengedwe.

IV. Satifiketi ndi miyezo

1, miyezo yotsatizana

IEC 61158: Zingwe za Profinet ziyenera kutsatira miyezo ya International Electrotechnical Commission (IEC), monga IEC 61158.

Chitsanzo cha ISO/OSI: Zingwe za Profinet ziyenera kutsatira miyezo ya layer physical ndi data link layer ya chitsanzo cha ISO/OSI.

V. Njira yosankha

1. Kuwunika zofunikira pa ntchito

Mtunda wotumizira: Kutengera ndi momwe chingwecho chikugwiritsidwira ntchito, sankhani mtundu woyenera wa chingwecho. Mtunda wotumizira wautali ukhoza kusankha chingwe cha 24 AWG, ndipo mutu wautali umalimbikitsidwa kusankha chingwe cha 22 AWG.

Mkhalidwe wa chilengedwe: Sankhani chingwe choyenera malinga ndi kutentha, chinyezi, kugwedezeka ndi zinthu zina zomwe zili pamalo oyika. Mwachitsanzo, sankhani chingwe cholimba kutentha kwambiri cha malo otentha kwambiri ndi chingwe chosalowa madzi cha malo ozizira.

2, sankhani mtundu woyenera wa chingwe

Chingwe chopindika chotetezedwa: Chingwe chopindika chotetezedwa chikulimbikitsidwa kuti chigwiritsidwe ntchito m'malo ambiri amafakitale kuti muchepetse kusokonezeka kwa maginito ndi kulankhulana molunjika.

Chingwe chopindika chosatetezedwa: kokha pamene pali kusokonezeka kwa maginito, chingwe chopindika chosatetezedwa ndi chochepa.

3, ganizirani za kusinthasintha kwa chilengedwe

Kuchuluka kwa kutentha, mulingo wa chitetezo, kugwedezeka ndi kukana kugwedezeka, kukana mankhwala: sankhani zingwe zomwe zingagwire ntchito mokhazikika pamalo enieni ogwiritsira ntchito.
