Mubikorwa bigezweho byinganda, insinga za PROFINET zigize itumanaho ryizewe ryitumanaho rihuza abagenzuzi, ibikoresho bya I / O, nibikoresho byumurima. Mugihe guhitamo umugozi wiburyo ari ngombwa, kugerageza imikorere yayo no kwizerwa ni ngombwa kimwe.
Mugihe inganda zikomeje gukoresha automatike kugirango zongere imikorere nubushobozi, uruhare rwinsinga rugenda rugaragara cyane. Guhitamo umugozi mwiza wa PROFINET ntabwo ari uguhuza gusa; ni ngombwa gusuzuma ibintu nkuburebure bwa kabili, gukingira, nibidukikije kugirango tumenye neza imikorere. Umugozi watoranijwe neza urashobora kunoza umuvuduko wo kohereza amakuru no kugabanya ubukererwe, bigira uruhare muri rusange sisitemu yitabira kandi ikora neza.
Ariko, akamaro ko guhitamo insinga ya PROFINET ikwiye karenze guhitamo ibicuruzwa bikwiye; isuzuma rikomeye ni ingenzi kugira ngo hemezwe imikorere yayo n'uburyo ikora mu buryo bufatika. Kunanirwa kwa insinga bishobora guteza imbogamizi zikomeye mu mikorere, harimo no kudakora neza mu buryo butunguranye no gukora amakosa mu itumanaho rimwe na rimwe, amaherezo bigatera gusana bihenze bigahungabanya umusaruro kandi bigagira ingaruka ku nyungu.
1. Impamvu gupima PROFINET Cables ari ingenzi
PROFINET ni inganda yemewe ya Ethernet yinganda ituma itumanaho ryigihe hagati yibikoresho mubidukikije bikora. Mugihe amashyirahamwe agenda yishingikiriza kuri tekinoroji kugirango atezimbere kandi yorohereze inzira, akamaro ko kwemeza ubuziranenge n’imikorere yinsinga za PROFINET ntishobora kuvugwa. Kugerageza insinga ntabwo ari ingamba zo gukumira gusa - ni intambwe ikomeye yo kurinda ibikorwa remezo byose.
Gupima insinga za PROFINET zitanga inyungu enye zingenzi:
-
Kohereza amakuru mu buryo buhorahomukurinda gutakaza paki no kunanirwa gutumanaho.
-
Umuyoboro wizewe, kugabanya igihe gitunguranye.
-
Kubahiriza ibipimo, byemeza kubahiriza ibisabwa na IEC 61158 na PROFINET.
-
Kuzigamamugushakisha amakosa mbere yuko yiyongera muburyo bwa sisitemu.
2. Ibyingenzi byingenzi byerekana ibipimo
Mugihe cyo kugerageza insinga za PROFINET, hagomba gusuzumwa ibintu bikurikira:
-
Ubunyangamugayo- iremeza kohereza amakuru neza, atagoretse.
-
Guhuza- PROFINET mubisanzwe isaba 100Ω Cat5e / Cat6 cabling.
-
Crosstalk (GIKURIKIRA na FEXT)- irinda kwivanga hagati ya kabili.
-
Kwitonda- gupima gutakaza ibimenyetso hejuru yuburebure.
-
Garuka igihombo- gusuzuma ibitekerezo biterwa no kurangiza nabi.
-
Gukingira neza- ingenzi mubidukikije byuzuye urusaku.
-
Kwangirika kumubiri- gukata, kunama, cyangwa kinks birashobora gutesha agaciro imikorere.
Urugero rw'umugozi:
Ubwoko bwa PROFINET B / C inganda Cat5e Ethernet umugozi, IP67-yerekana D-code ya M12 yumugabo-ku-gore, SF / UTP ikingiwe kabiri 22AWG imiyoboro ihagaze, urwego rwo hejuru rwinganda zo hanze, PLTC yagenwe, ikoti ryatsi rya TPE.
3. Uburyo bwo gupima insinga za PROFINET
1) Kugenzura Amashusho
Gusuzuma neza amaso ni intambwe ya mbere mu gusuzuma ubuziranenge bw'insinga. Reba ibimenyetso byose by'uko insinga zangiritse, zangiritse, cyangwa za pin zigonze. Suzuma uburebure bw'insinga kugira ngo urebe niba hari stress ifatika, zigonze cyane, cyangwa niba hari uburinzi bugaragara. Muri rusange, komeza urebe ko insinga zigonze zingana n'inshuro umunani z'umurambararo kugira ngo wirinde kwangirika kw'imbere mu muyoboro w'amashanyarazi.
2) Kwipimisha Gukomeza
Kwipimisha ubudahwema byemeza ko abayobora umunani bose bahujwe neza kugeza kumpera. Ibi birerekana imiyoboro ifunguye, ikabutura, cyangwa insinga zambutse zishobora guhagarika itumanaho. Ikigereranyo cyoroshye cyogupima cyangwa multimeter irashobora kugenzura ubudahwema mugihe cyo kwishyiriraho cyangwa kugenzura.
3) Kwipimisha Wiremap
Ikizamini cya Wiremap kigenzura neza pin umukoro ukurikije TIA-568A cyangwa TIA-568B. Irerekana ibice bibiri bidashobora kugaragara mubizamini bikomeza ariko bishobora kubangamira ubwiza bwibimenyetso. Kwemeza imiterere ya wiring bifasha gukomeza imikorere ihamye no kubahiriza ibipimo.
4) Ikizamini cyo Kwerekana Ubunyangamugayo
Ikizamini cyubunyangamugayo cyerekana ubushobozi bwumugozi wo kohereza amakuru nta kwangirika mugupima attenuation, kwambukiranya, hamwe na impedance. Ibikoresho nka Fluke Networks DSX CableAnalyser ikoreshwa muburyo bwo kwemeza insinga kugirango zubahirize ibipimo bya Ethernet na PROFINET.
5) Kugenzura uburinzi n'ubutaka
Iki kizamini cyemeza ko gukingira bikomeje muri kabili no guhuza, kandi bikagaragaza ibibazo byashingirwaho bishobora kongera kwandura EMI. Gukingira neza hamwe nubutaka nibyingenzi mubidukikije byurusaku.
6) Kwipimisha Ikosa Rito (BERT)
BERT ipima amakosa yukuri yohereza amakuru munsi yumutwaro. Mugusuzuma ibipimo byamakosa mugihe cyo gukora, iki kizamini gitanga isuzuma rifatika ryimikorere ya kabili mumikoreshereze yisi-ikomeye - imiyoboro isaba kwizerwa cyane nubukererwe buke.
7) Kwipimisha Ibidukikije
Igeragezwa ryibidukikije ryerekana insinga kubushyuhe bukabije, kunyeganyega, ubushuhe, nibindi bihe bibi kugirango hamenyekane igihe kirekire mubidukikije cyangwa hanze. Umugozi wa PROFINET washyizwe hanze akenshi ukoresha ikoti rya PUR cyangwa PE kugirango urwanye imirasire ya UV hamwe n’imiti.
Urugero rw'umugozi:
Ubwoko bwa PROFINET B / C inganda Cat5e Ethernet umugozi, IP67-yerekana D-code ya M12 yumugabo-wumugabo, SF / UTP ikingiwe kabiri 22AWG imiyoboro ihagaze, urwego rwohejuru rwimbere rwo hanze, PLTC yagenwe, ikoti ryatsi rya TPE.
4. Ibikoresho bisabwa
Inzego zitandukanye zipima ibikoresho byemeza uburinganire bwa PROFINET no kubahiriza:
-
Abapima ibanze- Kubikomeza byihuse no kugenzura wiremap.
-
Abapima ibyemezo byambere (urugero, Fluke, Korohereza)- Kugenzura niba byubahirijwe byuzuye na PROFINET na Ethernet mugupima attenuation, kwambukiranya, inzitizi, nibindi byinshi.
-
Abasesenguzi b'urusobe- Suzuma imikorere yigihe-nyacyo, ukurikirane ireme ryitumanaho, kandi umenye ibibazo byimikorere.
5. Inama zo Kwipimisha Kwizewe
-
Buri gihe gerageza mbere yo kwishyiriraho kugirango wirinde igihe gito kandi wongere ukore.
-
Andika insinga zose zapimwe kandi ubike raporo zemeza ibyemezo kugirango bikurikiranwe mugihe cyo kugenzura cyangwa kubungabunga.
-
Koresha imiyoboro ikingiwe mukarere ka EMI kugirango ukomeze ubudakemwa bwibimenyetso.
-
Simbuza umugozi uwo ariwo wose hamwe no gutakaza ibimenyetso birenze imipaka isanzwe (urugero,> 3 dB) kugirango umenye neza igihe kirekire.
6. Amakosa rusange yo Kwipimisha Kwirinda
Amakosa asanzwe abangamira ibizamini byukuri harimo:
-
Kureka gukingira igenzura mugace ka EMI hejuru.
-
Kwishingikiriza kubaguzi-bipimisha aho kuba ibikoresho byemewe na PROFINET.
-
Kwirengagiza amabwiriza yo kwishyiriraho.
-
Kunanirwa kugerageza insinga munsi yumutwaro nyirizina, kubuza gutahura ibibazo byimikorere bibaho mugihe gikora.
7. Ibyifuzo birebire byiringirwa
-
Koresha Cat6 cyangwa urwego rwohejuru rwa PROFINET insinga zose zishyirwaho.
-
Shiraho gahunda yo kubungabunga ibidukikije hamwe nogupima insinga buri gihe kugirango umenye kwangirika hakiri kare.
-
Hitamo insinga za LSZH cyangwa PUR-jacketed kugira ngo zikoreshwe mu buryo bugoye cyangwa busaba imbaraga nyinshi.
-
Bika kandi ukoreshe insinga neza, wirinde kunama bikabije cyangwa guhangayikishwa nubukanishi kugirango wirinde micro-crack zangiza imikorere yamashanyarazi mugihe.
8. Ibibazo Bikunze Kubazwa Kubijyanye na PROFINET Yipimishije
Q1: Ni kangahe insinga za PROFINET zigomba kugeragezwa?
Igisubizo: Gerageza mugihe cyo kwishyiriraho kandi buri mezi 12-18 murwego rwo kubungabunga ibidukikije.
Q2: Ikizamini gisanzwe cya Ethernet gishobora gukoreshwa mumigozi ya PROFINET?
Igisubizo: Bashobora gukora ibizamini byibanze, ariko PROFINET yemewe-ibizamini birasabwa kwizerwa byuzuye.
Q3: Ni ubuhe burebure ntarengwa bushyigikiwe na PROFINET?
Igisubizo: metero 100 kuri buri gice cyinsinga z'umuringa; fibre-optique PROFINET irashobora kwaguka cyane.
Q4: Nigute nshobora kugenzura ko gukingira bifite akamaro?
Igisubizo: Mugukora ikingira ikomeza no kugerageza ibizamini.
Q5: Ese kugerageza insinga za PROFINET hanze biratandukanye?
Igisubizo: Yego. Usibye ibizamini by'amashanyarazi, kurwanya UV, kwihanganira ubushyuhe, no kurinda ubushuhe nabyo birasuzumwa.
