Maitiro Ekuedza Kushanda Uye Kuvimbika kweProfinet Cables?

1. Sei Kuedza PROFINET Cables Kunokosha

PROFINET ndeye yakagamuchirwa yakawanda maindasitiri Ethernet chiyero chinogonesa chaiyo-nguva kutaurirana pakati pemidziyo munzvimbo dzekugadzira. Sezvo masangano ari kuramba achivimba neiyi tekinoroji kuti awedzere kubatana uye kugadzirisa maitiro, kukosha kwekuona kunaka uye kushanda kwePROFINET tambo hazvigone kuwedzeredzwa. Kuedza tambo idzi haingori nhanho yekudzivirira - inhanho yakakosha mukuchengetedza yese network network.

Kuedza PROFINET tambo kunovimbisa mana makuru mabhenefiti:

1. Consistent data transmissionnekudzivirira kurasikirwa kwepaketi uye kukundikana kwekukurukurirana.

2. Network kuvimbika, kuderedza nguva yekumbomira basa isingatarisirwi.

3. Kutevedzera mitemo, kusimbisa kutevedzera IEC 61158 uye PROFINET zvinodiwa.

4. Kuchengetedza marinekuona zvikanganiso zvisati zvawedzera mukutadza kwehurongwa.

2. Key Performance Parameters kuti Muedze

Paunenge uchiyedza PROFINET tambo, zvinotevera zvinhu zvinofanirwa kuongororwa:

• Chiratidzo chekuvimbika- inochengetedza kuchena, kusakanganiswa-isina kutapurirana data.

• Impedance kuenzanisa- PROFINET inowanzoda 100Ω Cat5e/Cat6 cabling.

• Crosstalk (NEXT uye FEXT)- inodzivirira kukanganisa pakati petambo dzetambo.

• Attenuation- inoyera kurasikirwa kwechiratidzo pamusoro pehurefu hwetambo.

• Dzorera kurasikirwa- inoongorora kufungidzira kunokonzerwa nekutadza kupera.

• Kudzivirira kushanda zvakanaka- yakakosha munzvimbo dzine ruzha dzeindasitiri.

• Kukuvadzwa mumuviri- kuchekwa, kubhenda, kana kinks kunogona kukanganisa kuita.

Muenzaniso tambo:
PROFINET mhando B/C indasitiri Cat5e Ethernet tambo, IP67-yakatemerwa D-coded M12 murume-kune-mukadzi, SF/UTP yakapetwa kaviri-yakavharirwa 22AWG yakasungwa conductors, yakakwira-flex yekunze maindasitiri giredhi, PLTC yakayerwa, yegirini TPE bhachi.

3. Nzira dzekuedza PROFINET Cables

1) Kuongorora Kwekuona

Kunyatsoongorora kwekuona ndiyo danho rekutanga pakuongorora kutendeseka kwetambo. Tarisa zvese zvinobatanidza zviratidzo zvekukuvara, ngura, kana mapini akabhenda. Ongorora kureba kwetambo nekuda kwekushushikana kwemuviri, kubhenda kwakasimba, kana kudzivirirwa kwakafumurwa. Kazhinji, chengetedza diki bend radius yakaenzana nekasere dhayamita yetambo kudzivirira mukati kondakita kukuvara.

2) Kuedzwa Kuenderera Mberi

Kuenderera mberi kuyedza kunoita kuti ese maconductor masere anyatsobatanidzwa kumagumo kusvika kumagumo. Izvi zvinozivisa maseketi akavhurika, zvikabudura, kana waya dzakayambuka dzinogona kukanganisa kutaurirana. Yakareruka tambo tester kana multimeter inogona kuonesa kuenderera kwekutanga panguva yekuisa kana kugadzirisa macheki.

3) Wiremap Testing

Wiremap kuyedzwa kunosimbisa epini inopihwa zvinoenderana neTIA-568A kana TIA-568B zviyero. Inotaridza kupatsanurwa maviri maviri anogona kusaoneka muyedzo yekuenderera mberi asi anogona kukanganisa zvakanyanya kunaka kwechiratidzo. Kusimbisa iyo wiring dhizaini kunobatsira kuchengetedza kuita kwakafanana uye kutevedzera zviyero.

4) Chiratidzo cheKutendeseka Kuedzwa

Signal kutendeseka kuyedzwa inoongorora kugona kwetambo kufambisa data pasina kushatisa nekuyera attenuation, crosstalk, uye impedance. Zvishandiso zvakaita seFluke Networks DSX CableAnalyzer zvinowanzo shandiswa kusimbisa tambo dzekutevedzera Ethernet uye PROFINET maitiro ekuita.

5) Kudzivirira & Grounding Verification

Muedzo uyu unosimbisa kuti kudzivirira kunoenderera mukati metambo uye majoini, uye inotaridza nyaya dzekudzika dzinogona kuwedzera kubatwa neEMI. Kudzivirira kwakaringana nekudzika pasi kwakakosha munzvimbo dzine ruzha dzemaindasitiri.

6) Bit Error Rate Testing (BERT)

BERT inoyera chaiyo zvikanganiso zvekufambisa data pasi pemutoro. Nekuongorora chiyero chekukanganisa panguva yekushanda, iyi bvunzo inopa kuongororwa kwechokwadi kwekuita kwetambo mukushandiswa kwepasirese-yakakosha kune network inoda kuvimbika kwakanyanya uye yakaderera latency.

7) Environmental Stress Testing

Kuyedzwa kwezvakatipoteredza kunofumura tambo kune tembiricha yakanyanyisa, vibration, mwando, uye mamwe mamiriro akaomarara kuratidza kusimba munzvimbo dzeindasitiri kana dzekunze. Kunze-yakatemerwa PROFINET tambo dzinowanzoshandisa PUR kana PE jaketi kuramba UV mwaranzi uye kuratidzwa kwemakemikari.

Muenzaniso tambo:
PROFINET mhando B/C indasitiri Cat5e Ethernet tambo, IP67-yakatemerwa D-coded M12 murume-kune-murume, SF/UTP yakapetwa kaviri 22AWG stranded conductors, yakakwirira-flex yekunze giredhi, PLTC yakayerwa, yegirini TPE bhachi.

4. Zvishandiso zveKuedza Zvinokurudzirwa

Akasiyana mazinga emidziyo yekuyedza anovimbisa PROFINET tambo kutendeseka uye kutevedzera:

• Basic testers-Kukurumidza kuenderera mberi uye wiremap cheki.

• Yepamberi certification testers (semuenzaniso, Fluke, Kupfava)-Simbisa kuteedzera kuzere nePROFINET uye Ethernet zviyero nekuyera attenuation, crosstalk, impedance, nezvimwe.

• Network analyzers-Ongorora chaiyo-nguva network kuita, tarisisa kunaka kwekutaurirana, uye kuona nyaya dzekushanda.

5. Mazano eKuedzwa kwakavimbika

• Gara uchiyedza usati waisa kuti udzivise kudhura nguva uye kushandazve.

• Nyora tambo dzese dzakaedzwa uye mishumo yekuchengetera zvitupa zvekuteedzera panguva yekuongorora kana kugadzirisa.

• Shandisa zvibatanidza zvakavharidzirwa munzvimbo dzakakwirira-EMI kuchengetedza chiratidzo chekuvimbika.

• Tsiva chero tambo nekurasikirwa kwechiratidzo kudarika miganho yakajairwa (semuenzaniso,> 3 dB) kuve nechokwadi chekuvimbika kwetiweki kwenguva refu.

6. Common Testing Mistakes to Dzivisa

Zvikanganiso zvakajairika zvinokanganisa chokwadi chekuyedza zvinosanganisira:

• Kusvetuka kuchengetedzwa kwekudzivirira munzvimbo dzakakwirira-EMI.

• Kuvimba nevatengi-giredhi testers pane PROFINET-yakasimbiswa michina.

• Kuregeredza nhungamiro yekuisa mugadziri.

• Kukundikana kuyedza tambo dziri pasi pemutoro chaiwo, zvichidzivirira kuonekwa kwematambudziko ekushanda anoitika panguva yekushanda chete.

7. Kuvimbika Kwenguva Yakareba Mazano

• Shandisa Cat6 kana yepamusoro-yakatemerwa PROFINET tambo kune ese matsva ekuisa.

• Gadzira chirongwa chekudzivirira chekuchengetedza ne periodic tambo yekuongorora kuti uone kuderera kwekutanga.

• Sarudza LSZH kana PUR-jaketi tambo dzenzvimbo dzakaomarara kana dzinoda.

• Chengeta uye bata tambo nemazvo, uchidzivisa kukotama zvakanyanya kana kumanikidzwa kwemagetsi kudzivirira kutsemuka kudiki kunokanganisa mashandiro emagetsi nekufamba kwenguva.

8. Mibvunzo Inowanzo bvunzwa Nezve PROFINET Cable Testing

Q1: Kangani tambo dzePROFINET dzinofanira kuedzwa?
A: Edzai panguva yekuisa uye yega yega 12-18 mwedzi sechikamu chekudzivirira kuchengetedza.

Q2: Ko yakajairwa Ethernet testers inogona kushandiswa kune PROFINET tambo?
A: Vanogona kuita bvunzo dzepakutanga, asi vanoedza vane certification yePROFINET vanokurudzirwa kuti vavimbike zvizere.

Q3: Ndeipi yakakura yakatsigirwa tambo urefu hwePROFINET?
A: 100 mamita pachikamu chetambo dzemhangura; fiber-optic PROFINET inogona kuwedzera kure.

Q4: Ndingaona sei kuti kudzivirira kunoshanda?
A: Nekuita kudzivirira kuenderera uye bvunzo dzepasi.

Q5: Kuedza kunze PROFINET tambo dzakasiyana here?
A: Hongu. Pamusoro pekuyedzwa kwemagetsi, UV kuramba, tembiricha kutsungirira, uye hunyoro kuchengetedzwa kunoongororwawo.
