Ungakuhlola Kanjani Ukusebenza Nokuthembeka Kwezintambo ze-PROFINET?

1. Kungani Ukuhlola Amakhebula e-PROFINET Kubalulekile

I-PROFINET iyindinganiso ye-Ethernet yezimboni eyamukelwa kabanzi evumela ukuxhumana kwesikhathi sangempela phakathi kwamadivayisi ezindaweni zokukhiqiza. Njengoba izinhlangano zithembela kakhulu kulobu buchwepheshe ukuthuthukisa ukuxhumana nokwenza lula izinqubo, ukubaluleka kokuqinisekisa ikhwalithi nokusebenza kwezintambo ze-PROFINET akunakuphikiswa. Ukuhlola lezi zintambo akuyona nje indlela yokuvimbela—kuyisinyathelo esibalulekile ekuvikeleni yonke ingqalasizinda yenethiwekhi.

Ukuhlola izintambo ze-PROFINET kuqinisekisa izinzuzo ezine ezinkulu:

1. Ukudluliswa kwedatha okuhlala njalongokuvimbela ukulahleka kwephakethe kanye nokwehluleka kokuxhumana.

2. Ukuthembeka kwenethiwekhi, ukunciphisa isikhathi sokungasebenzi esingalindelekile.

3. Ukuthobela amazinga, eqinisekisa ukunamathela ezidingweni ze-IEC 61158 kanye ne-PROFINET.

4. Ukonga izindlekongokuthola amaphutha ngaphambi kokuba akhule abe ukwehluleka kwesistimu.

2. Amapharamitha Okusebenza Okubalulekile Okufanele Uwahlole

Uma kuhlolwa izintambo ze-PROFINET, kufanele kuhlolwe izici ezilandelayo:

• Ubuqotho besiginali– kuqinisekisa ukudluliswa kwedatha okuhlanzekile, okungenasiphazamiso.

• Ukufaniswa kwe-Impedance– I-PROFINET ngokuvamile idinga izintambo ze-100Ω Cat5e/Cat6.

• I-Crosstalk (NEXT kanye ne-FEXT)– kuvimbela ukuphazamiseka phakathi kwama-cable pairs.

• Ukuncipha– kulinganisa ukulahleka kwesiginali ngaphezu kobude bekhebula.

• Ukulahlekelwa yimbuyiselo– ihlola ukucabanga okubangelwa ukuqeda okubi.

• Ukusebenza kahle kokuvikela– kubalulekile ezindaweni zezimboni ezinomsindo.

• Umonakalo ongokwenyama– ukusikeka, ukugoba, noma ukugoba kungalimaza ukusebenza.

Isibonelo sekhebula:
Ikhebula le-Profinet B/C le-industrial Cat5e Ethernet, i-M12 enekhodi ye-D enesilinganiso se-IP67, ama-conductor angu-22AWG avikelwe kabili e-SF/UTP, izinga lezimboni langaphandle eliguquguqukayo kakhulu, i-PLTC enesilinganiso, ijakethi ye-TPE eluhlaza.

3. Izindlela Zokuhlola Amakhebula E-PROFINET

1) Ukuhlolwa Okubonakalayo

Ukuhlola okubonakalayo okuphelele kuyisinyathelo sokuqala sokuhlola ubuqotho bekhebula. Hlola zonke izixhumi ukuze ubone izimpawu zomonakalo, ukugqwala, noma izikhonkwane ezigobile. Hlola ubude bekhebula ukuze ubone ukucindezeleka ngokomzimba, ukugoba okuqinile, noma ukuvikela okuveziwe. Ngokuvamile, gcina irediyasi yokugoba encane elingana nobubanzi bekhebula obuphindwe kasishiyagalombili ukuze uvimbele umonakalo wangaphakathi womqhubi.

2) Ukuhlolwa Kokuqhubeka

Ukuhlolwa kokuqhubeka kuqinisekisa ukuthi wonke ama-conductor ayisishiyagalombili axhunywe kahle kusukela ekuqaleni kuya ekugcineni. Lokhu kuhlonza amasekethe avulekile, ama-short, noma izintambo ezihlanganisiwe ezingaphazamisa ukuxhumana. Umhloli wekhebula olula noma i-multimeter ingaqinisekisa ukuqhubeka okuyisisekelo ngesikhathi sokuhlolwa kokufakwa noma kokugcinwa.

3) Ukuhlolwa kwe-Wiremap

Ukuhlolwa kwe-Wiremap kuqinisekisa ukwabiwa kwephini okulungile ngokwezindinganiso ze-TIA-568A noma ze-TIA-568B. Kuhlonza ama-split pair angase angabonakali ekuhlolweni okuyisisekelo kokuqhubeka kodwa angalimaza kakhulu ikhwalithi yesignali. Ukuqinisekisa ukwakheka kwezintambo kusiza ukugcina ukusebenza okuhambisanayo kanye nokuhambisana nezindinganiso.

4) Ukuhlolwa Kobuqotho Besignali

Ukuhlolwa kobuqotho besiginali kuhlola ikhono lekhebula lokudlulisa idatha ngaphandle kokuwohloka ngokulinganisa ukuncishiswa, ukuxoxa nge-crosstalk, kanye ne-impedance. Amathuluzi anjenge-Fluke Networks DSX CableAnalyzer ngokuvamile asetshenziselwa ukuqinisekisa izintambo zokuhambisana nezindinganiso zokusebenza ze-Ethernet kanye ne-PROFINET.

5) Ukuqinisekiswa Kokuvikela Nokumisa Isisekelo

Lokhu kuhlolwa kuqinisekisa ukuthi ukuvikela kuyaqhubeka kuyo yonke ikhebula nezixhumi, futhi kukhomba izinkinga zokusekela phansi ezingase zandise ukuthambekela kwe-EMI. Ukuvikela nokusekela kahle kubalulekile ezindaweni zezimboni ezinomsindo.

6) Ukuhlolwa Kwezinga Lephutha Le-Bit (BERT)

I-BERT ilinganisa amaphutha okudlulisa idatha angempela ngaphansi komthwalo. Ngokuhlola amazinga amaphutha e-bit ngesikhathi sokusebenza, lokhu kuhlola kunikeza ukuhlolwa okungokoqobo kokusebenza kwekhebula ekusetshenzisweni kwangempela—okubalulekile kumanethiwekhi adinga ukuthembeka okuphezulu kanye nokubambezeleka okuphansi.

7) Ukuhlolwa Kokucindezeleka Kwemvelo

Ukuhlolwa kwemvelo kuveza izintambo emazingeni okushisa aphezulu, ukudlidliza, umswakama, kanye nezinye izimo ezinzima ukuqinisekisa ukuqina ezindaweni zezimboni noma zangaphandle. Izintambo ze-PROFINET ezilinganiselwe ngaphandle zivame ukusebenzisa amajakethi e-PUR noma e-PE ukuze zimelane nemisebe ye-UV kanye nokuchayeka kwamakhemikhali.

4. Amathuluzi Okuhlola Anconyiwe

Amazinga ahlukene emishini yokuhlola aqinisekisa ubuqotho kanye nokuhambisana kwekhebula le-PROFINET:

• Abahloli abayisisekelo– Ukuze kuqhutshekwe ngokushesha kanye nokuhlolwa kwemephu yentambo.

• Abahloli bezitifiketi ezithuthukisiwe (isb., i-Fluke, i-Softing)- Qinisekisa ukuhambisana ngokugcwele nezindinganiso ze-PROFINET ne-Ethernet ngokulinganisa ukuncishiswa, ukuxoxa nge-crosstalk, impedance, nokuningi.

• Abahlaziyi benethiwekhi- Hlola ukusebenza kwenethiwekhi ngesikhathi sangempela, qapha ikhwalithi yokuxhumana, futhi uthole izinkinga zokusebenza.

5. Amathiphu Okuhlola Okuthembekile

• Hlola njalo ngaphambi kokufaka ukuze ugweme isikhathi esibizayo sokungasebenzi kanye nokulungisa kabusha.

• Faka amalebula kuzo zonke izintambo ezivivinyiwe kanye nemibiko yesitifiketi sesitolo ukuze kutholakale ukuthi ziyalandeleka yini ngesikhathi sokuhlolwa noma ukulungiswa.

• Sebenzisa izixhumi ezivikelwe ezindaweni ezine-EMI ephezulu ukuze ugcine ubuqotho besiginali.

• Shintsha noma iyiphi ikhebula ngokulahlekelwa yisignali okungaphezu kwemingcele ejwayelekile (isb., >3 dB) ukuqinisekisa ukuthembeka kwenethiwekhi yesikhathi eside.

6. Amaphutha Okuhlola Okuvamile Okufanele Uwagweme

Amaphutha avamile abeka engcupheni ukunemba kokuhlolwa afaka:

• Ukweqa ukuqinisekiswa kokuvikela ezindaweni ezine-EMI ephezulu.

• Ukuthembela kubahloli bezinga labathengi kunemishini eqinisekiswe yi-PROFINET.

• Ukungayinaki imithethonqubo yokufaka abakhiqizi.

• Ukwehluleka ukuhlola izintambo ngaphansi komthwalo wangempela, okuvimbela ukutholakala kwezinkinga zokusebenza ezenzeka ngesikhathi sokusebenza kuphela.

7. Izincomo Zokuthembeka Kwesikhathi Eside

• Sebenzisa izintambo ze-Cat6 noma ze-PROFINET ezinesilinganiso esiphezulu kuzo zonke izinto ezintsha ezifakiwe.

• Hlela uhlelo lokulungisa oluvimbela ukonakala ngokuhlolwa kwekhebula njalo ukuze kutholakale ukubola kusenesikhathi.

• Khetha izintambo ezinejakethi ze-LSZH noma ze-PUR ukuze uthole izindawo ezinzima noma ezidinga amandla amaningi.

• Gcina futhi uphathe izintambo ngendlela efanele, ugweme ukugoba ngokweqile noma ukucindezeleka komshini ukuze uvimbele imifantu emincane eyonakalisa ukusebenza kukagesi ngokuhamba kwesikhathi.
