He kawa whakawhitiwhiti kōrero ahumahi a Profinet e ahu mai ana i te Ethernet, e whakamahia whānuitia ana i roto i ngā pūnaha whakahaere aunoa, ko ngā whakaritenga motuhake o te taura Profinet e aro nui ana ki ngā āhuatanga ā-tinana, te mahi hiko, te urutau taiao me ngā whakaritenga tāutanga. Ka arotahi tēnei tuhinga ki te taura Profinet mō te tātari taipitopito.
I. Ngā Āhuatanga ā-Tinana
1, momo taura
Takirua Miro Ārai (STP/FTP): E taunakihia ana te Takirua Miro Ārai hei whakaiti i te wawaotanga hikohiko (EMI) me te whakawhitiwhiti kōrero. Ka taea e te takirua miro ārai te ārai i te wawaotanga hikohiko o waho, me te whakapai ake i te pumau me te pono o te tuku tohu.
Te Takirua Miro Kore-Pare (UTP): Ka taea te whakamahi i te Takirua Miro Kore-Pare i roto i ngā taiao he iti ake te pokanoa hikohiko, engari kāore i te tūtohutia mō te whakamahi i roto i ngā taiao ahumahi.
2, hanganga taura
E whā ngā takirua taura takirua-whiri: Ko te taura Profinet he maha ngā takirua taura takirua-whiri, ko ia takirua he waea e rua ngā waea hei tuku raraunga me te tuku hiko (mēnā e tika ana).
Te Diameter Waea: Ko ngā diameter waea he 22 AWG, 24 AWG, 26 AWG rānei, i runga i te tawhiti tuku me ngā whakaritenga kaha tohu. He pai te 24 AWG mō ngā tawhiti tuku roa, ā, he pai te 26 AWG mō ngā tawhiti poto.
3、Hononga
Hononga RJ45: Ka whakamahia e ngā taura Profinet ngā hononga RJ45 paerewa hei whakarite i te hototahitanga ki ngā taputapu Profinet.
Tikanga Maukati: E taunakihia ana ngā hononga RJ45 me te tikanga maukati mō ngā taiao ahumahi hei ārai i ngā hononga koretake, hei whakarite hoki i te pono o te hononga.
Tuarua, te urutau ki te taiao
1, Awhe pāmahana
Hoahoa pāmahana whānui: Me taea e te taura Profinet te mahi tika i roto i te whānuitanga pāmahana whānui, me te nuinga o te wā e hiahiatia ana hei tautoko i te whānuitanga pāmahana -40°C ki te 70°C.
2, taumata tiaki
Te taumata tiaki teitei: Kōwhiria ngā taura me te taumata tiaki teitei (hei tauira, IP67) hei ārai i te urunga mai o te puehu me te kohu wai mō ngā taiao ahumahi kino.
3, ātete wiri me te ru
Kaha ā-ringa: Me pai te ātete o ngā taura Profinet ki te wiri me te ru, kia tika ai mō ngā taiao wiri me te ru.
4, ātete matū
Ātete ki te hinu, te waikawa me te kawakore: Kōwhiria ngā taura he ātete matū pēnei i te hinu, te waikawa me te kawakore kia urutau ki ngā taiao ahumahi rerekē.
III. Ngā Whakaritenga Tāutanga
1, Ara waea
Āraia te pokanoa hiko kaha: me karo te whakatakotoranga whakarara o ngā waea hiko me ngā raina hiko ngaohiko teitei, ngā motuka me ētahi atu taputapu hiko kaha i roto i te waea hei whakaiti i te pokanoa hikohiko.
Te tahora whaitake: Te whakamahere whaitake o te ara waea, kia kore ai e piko rawa, e pēhia rānei te taura, kia mau ai te āhua o te taura.
2. Tikanga whakatika
Taupoki pumau: Whakamahia te taupoki pumau me te taputapu e tika ana hei whakarite kia mau te taura hei ārai i te wiri, i te nekehanga rānei e puta mai ana i ngā hononga ngoikore.
Te awa waea me te paipa: I roto i ngā taiao uaua, e taunakihia ana kia whakamahia te awa waea, te paipa rānei hei tiaki taura hei ārai i ngā kino ā-mīhini me ngā pānga ki te taiao.
IV. Te Tiwhikete me ngā Paerewa
1. Ngā paerewa tutuki
IEC 61158: Me tutuki ngā taura Profinet i ngā paerewa o te International Electrotechnical Commission (IEC), pērā i te IEC 61158.
Tauira ISO/OSI: Me tutuki ngā taura Profinet ki ngā paerewa paparanga ā-tinana me te paparanga hononga raraunga o te tauira ISO/OSI.
V. Tikanga whiriwhiri
1. Aromatawai i ngā whakaritenga tono
Tawhiti tuku: E ai ki te whakamahinga tuturu o te tawhiti tuku, me whiriwhiri te momo taura e tika ana. Ka taea te whiriwhiri i te taura 24 AWG mō te tuku tawhiti poto, engari ko te taura 22 AWG mō te tuku tawhiti roa.
Ngā āhuatanga taiao: Tīpakohia te taura e tika ana kia rite ki te pāmahana, te haumākū, te wiri me ētahi atu āhuatanga o te taiao tāutanga. Hei tauira, tīpakohia te taura ātete pāmahana teitei mō te taiao pāmahana teitei me te taura ātete wai mō te taiao haumākū.
2, whiriwhiria te momo taura tika
Taura takirua-whiri kua āraia: E taunakihia ana te whakamahi i te taura takirua-whiri kua āraia i roto i te nuinga o ngā taiao ahumahi hei whakaiti i te pokanoa hikohiko me te whakawhitiwhiti kōrero.
Taura takirua-whiri kāore i te āraihia: ko te taura takirua-whiri kāore i te āraihia anake i roto i te taiao o te pokanoa hikohiko.
3, whakaarohia te urutau taiao
Te awhe pāmahana, te taumata tiaki, te ātete wiri me te ru, te ātete matū: whiriwhiria ngā taura ka taea te mahi pumau i roto i te taiao tono tūturu.
