UVavanya njani ukuSebenza kunye nokuthembeka kweeCables zePROFINET?

1. Kutheni kubalulekile ukuvavanya i-PROFINET Cables

I-PROFINET yimigangatho eyamkelwe ngokubanzi ye-Ethernet yezoshishino eyenza unxibelelwano lwexesha langempela phakathi kwezixhobo kwiindawo zokuvelisa. Njengoko imibutho ithembela ngakumbi kule teknoloji ukunyusa uqhagamshelwano kunye nokulungelelanisa iinkqubo, ukubaluleka kokuqinisekisa umgangatho kunye nokusebenza kweentambo ze-PROFINET azikwazi ukugqithiswa. Ukuvavanya ezi ntambo akuyona nje indlela yokukhusela-linyathelo elibalulekileyo ekukhuseleni yonke iziseko zenethiwekhi.

Ukuvavanya iintambo ze-PROFINET kuqinisekisa izibonelelo ezine eziphambili:

1. Ukuhanjiswa kwedatha okuhambelanayongokuthintela ukulahleka kwepakethi kunye nokungaphumeleli konxibelelwano.

2. Ukuthembeka kwenethiwekhi, ukunciphisa ixesha lokungasebenzi elingalindelekanga.

3. Ukuthotyelwa kwemigangatho, eqinisekisa ukuthotyelwa kwe-IEC 61158 kunye neemfuno zePROFINET.

4. Ukongiwa kweendlekongokufumanisa iziphene phambi kokuba zinyuke ziye kukusilela kwenkqubo.

2. IiParamitha zokuSebenza eziPhambili zoVavanyo

Xa uvavanya iintambo zePROFINET, le miba ilandelayo kufuneka ivavanywe:

• Ingqibelelo yomqondiso- iqinisekisa ukuhanjiswa kwedatha okucocekileyo, okugqwethekileyo.

• Ukuthelekisa i-impedance-I-PROFINET idla ngokufuna i-100Ω Cat5e/Cat6 ikhowuli.

• I-Crosstalk (Elandelayo kunye ne-FEXT)– kuthintela ukuphazanyiswa phakathi kweeperi zentambo.

• Ukuthotywa- ukulinganisa ilahleko yesignali ngobude bekhebula.

• Buyisela ilahleko- Uvavanya imbonakalo ebangelwa kukupheliswa kakubi.

• Ukukhusela ukusebenza-ibaluleke kakhulu kwiindawo ezinengxolo yemizi-mveliso.

• Umonakalo womzimba- ukusika, ukugoba, okanye i-kinks kunokunciphisa ukusebenza.

Umzekelo wentambo:
Intambo ye-PROFINET yohlobo lwe-B/C ye-industrial Cat5e Ethernet, i-M12 eneekhowudi ze-D ezilinganiswe nge-IP67, ii-SF/UTP ezikhuselwe kabini ze-22AWG ezifakwe isikhuselo, uhlobo oluphezulu lwe-industrial yangaphandle, i-PLTC elinganiswe, ijakethi ye-TPE eluhlaza.

3. Iindlela zoVavanyo lwePROFINET Cables

1) Ukuhlolwa okubonakalayo

Ukuhlolwa okubonakalayo okucokisekileyo kuyinyathelo lokuqala lokuvavanya ukuthembeka kwentambo. Jonga zonke izihlanganisi iimpawu zomonakalo, umhlwa, okanye izikhonkwane ezigobileyo. Jonga ubude bentambo yoxinzelelo lomzimba, ukugoba okuqinileyo, okanye ukukhuselwa okuvezwayo. Ngokubanzi, gcina i-radius ye-bend encinci elingana namaxesha asibhozo ububanzi bekhebula ukukhusela umonakalo wangaphakathi we-conductor.

2) Uvavanyo oluqhubekayo

Uvavanyo oluqhubekayo luqinisekisa ukuba bonke abaqhubi abasibhozo badityaniswe ngokuchanekileyo ekupheleni ukuya ekupheleni. Oku kuchonga iisekethe ezivulekileyo, iifutshane, okanye iingcingo ezinqamlezileyo ezinokuphazamisa unxibelelwano. I-cable tester elula okanye i-multimeter inokuqinisekisa ukuqhubeka okusisiseko ngexesha lofakelo okanye ukuhlolwa kokugcinwa.

3) Uvavanyo lweWiremap

Uvavanyo lwe-Wiremap luqinisekisa ukunikezelwa kweephini ngokuchanekileyo ngokwemigangatho ye-TIA-568A okanye ye-TIA-568B. Luchonga ii-split pairs ezisenokungabonakali kuvavanyo olusisiseko lokuqhubeka kodwa zinokuphazamisa kakhulu umgangatho wesiginali. Ukuqinisekisa ulwakhiwo lwe-wiring kunceda ukugcina ukusebenza okulinganayo kunye nokuthobela imigangatho.

4) Uvavanyo loBulungisa beSignali

Uvavanyo lwengqibelelo yomqondiso luvavanya ukukwazi kwentambo ukusasaza idatha ngaphandle kokuthotywa ngokulinganisa ukuthomalalisa, i-crosstalk, kunye ne-impedance. Izixhobo ezifana neFluke Networks DSX CableAnalyzer ziqhele ukusetyenziselwa ukuqinisekisa iintambo zokuthotyelwa kwe-Ethernet kunye nePROFINET imigangatho yokusebenza.

5) UkuKhusela kunye nokuQinisekisa ukuQinisekisa

Olu vavanyo luqinisekisa ukuba ukhuselo luyaqhubeka kuyo yonke intambo kunye nezihlanganisi, kwaye ichonge imiba esisiseko enokunyusa ukuchaphazeleka kwi-EMI. Ukukhuselwa okufanelekileyo kunye nokubekwa phantsi kubalulekile kwindawo enengxolo yemizi-mveliso.

6) UVavanyo lweNyingeko yeBit (BERT)

I-BERT ilinganisa iimpazamo ezichanekileyo zothumelo lwedatha phantsi komthwalo. Ngokuvavanya imilinganiselo yempazamo encinci ngexesha lokusebenza, olu vavanyo lubonelela ngovavanyo oluyinyani lwentsebenzo yentambo kusetyenziso lwehlabathi lokwenyani-lubalulekile kuthungelwano olufuna ukuthembeka okuphezulu kunye ne-latency ephantsi.

7) Uvavanyo loxinzelelo lwendalo

Uvavanyo lwendalo esingqongileyo lubhentsisa iintambo kumaqondo obushushu agqithisileyo, ukungcangcazela, ukufuma, kunye nezinye iimeko ezirhabaxa ukuze kuqinisekiswe ubukho bexesha elide kwindawo yoshishino okanye yangaphandle. Iintambo ze-PROFINET ezilinganiswe ngaphandle zihlala zisebenzisa i-PUR okanye iibhatyi ze-PE ukuxhathisa imitha ye-UV kunye nokuvezwa kweekhemikhali.

Umzekelo wentambo:
PROFINET uhlobo B / C ishishini Cat5e Ethernet cable, IP67-rated D-coded M12 indoda-to-indoda, SF/UTP kabini shielded 22AWG abaqhubi stranded, high-flex ibakala langaphandle, PLTC rated, TPE ibhatyi eluhlaza.
