Ni ibihe bisabwa byihariye ku nsinga za Profinet?

Profinet ni protocole y'itumanaho ry'inganda ishingiye kuri Ethernet, ikoreshwa cyane muri sisitemu zo kugenzura imikorere y'ikoranabuhanga, ibisabwa byihariye bya Profinet cable byibanda ahanini ku miterere y'umubiri, imikorere y'amashanyarazi, kwihuza n'ibidukikije n'ibisabwa mu kuyishyiraho. Iyi nkuru izibanda ku muyoboro wa Profinet kugira ngo ikore isesengura ryimbitse.

I. Imiterere y'umubiri

1, ubwoko bw'insinga

Ihuriro ry’amashanyarazi rishobora gukumira ihungabana ry’amashanyarazi riturutse hanze no kunoza uburyo bwo kohereza ibimenyetso mu buryo buhamye no mu buryo bwizewe.

Unshielded Twisted Pair (UTP): Unshielded Twisted Pair ishobora gukoreshwa ahantu hadafite amashanyarazi menshi, ariko ntibyemewe gukoreshwa mu nganda.

2, imiterere y'insinga

Impande enye z'insinga zizunguruka: Insinga ya Profinet ubusanzwe iba irimo impande enye z'insinga zizunguruka, buri nsinga igizwe n'insinga ebyiri zo kohereza amakuru n'amashanyarazi (niba bibaye ngombwa).

Umurambararo w'insinga: Ubusanzwe umurambararo w'insinga ni 22 AWG, 24 AWG, cyangwa 26 AWG, bitewe n'intera yo kohereza n'imbaraga z'ikimenyetso. 24 AWG ikwiriye intera ndende yo kohereza, naho 26 AWG ikwiriye intera ngufi.

3, Umuhuza

Umuhuza wa RJ45: Insinga za Profinet zikoresha imihuza isanzwe ya RJ45 kugira ngo zihuze neza n'ibikoresho bya Profinet.

Uburyo bwo Gufunga: Ibikoresho bya RJ45 bifite uburyo bwo gufunga birasabwa ku nganda kugira ngo hirindwe ko imiyoboro idafite aho ihuriye kandi bigenzure ko imiyoboro ikora neza.

Icya kabiri, kwihutisha ibidukikije

1. Ingano y'ubushyuhe

Igishushanyo cy'ubushyuhe bunini: Insinga ya Profinet igomba kuba ishobora gukora neza mu bushyuhe bunini, akenshi isabwa kugira ngo ishyigikire ubushyuhe bwa -40 ° C kugeza kuri 70 ° C.

2. Urwego rw'uburinzi

Uburinzi buri hejuru: Hitamo insinga zifite uburinzi buri hejuru (urugero: IP67) kugira ngo wirinde ko ivumbi n'umwuka w'amazi byinjira mu nganda zikomeye.

3. Kudahusha no kurwanya guhungabana

Imbaraga za mekanike: Insinga za Profinet zigomba kuba zifite umuvuduko mwiza kandi zirwanya umuvuduko, zikwiriye ahantu hatembera no mu muvuduko.

4, kurwanya imiti

Ubudahangarwa bw'amavuta, aside na alkali: Hitamo insinga zifite ubudahangarwa bw'imiti nka peteroli, aside na alkali kugira ngo zihuze n'ibidukikije bitandukanye by'inganda.

III. Ibisabwa mu gushyiraho

1, Inzira yo gufunga insinga

Irinde ko amashanyarazi yangirika cyane: mu nsinga ugomba kugerageza kwirinda gushyiramo insinga z'amashanyarazi zifite ingufu nyinshi, moteri n'ibindi bikoresho by'amashanyarazi bikomeye kugira ngo ugabanye ko amashanyarazi yangirika cyane.

Imiterere ikwiye: Gutegura neza inzira y'insinga, kugira ngo hirindwe kunama cyangwa gukanda cyane ku nsinga, kugira ngo hamenyekane ko insinga ikora neza.

2, Uburyo bwo gukosora

Agakingirizo gahamye: Koresha agakingirizo gahamye n'icyuma gikwiye kugira ngo urebe neza ko insinga ihamye neza kugira ngo wirinde guhinda cyangwa kugenda bitewe n'imiyoboro idakora neza.

Umuyoboro w'insinga n'umuyoboro: Mu bidukikije bigoye, ni byiza gukoresha umuyoboro w'insinga cyangwa umuyoboro mu kurinda insinga kugira ngo hirindwe kwangirika kwa mekanike n'ingaruka ku bidukikije.

IV. Impamyabushobozi n'amahame ngenderwaho

1. Amahame ngenderwaho yo kubahiriza amategeko

IEC 61158: Insinga za Profinet zigomba kubahiriza amahame ya Komisiyo Mpuzamahanga y’Ubuhanga mu by’Ikoranabuhanga (IEC), nka IEC 61158.

Icyitegererezo cya ISO/OSI: Insinga za Profinet zigomba kubahiriza amahame ngenderwaho y’urwego rw’ifatizo n’uruhererekane rw’amakuru bya ISO/OSI.

V. Uburyo bwo guhitamo

1. Isuzuma ry'ibisabwa mu gusaba

Intera yo kohereza: Hakurikijwe ikoreshwa ry’intera yo kohereza, hatoranywa ubwoko bw’insinga ikwiye. Kohereza mu ntera ngufi bishobora guhitamo insinga ya 24 AWG, kohereza mu ntera ndende ni byiza guhitamo insinga ya 22 AWG.

Imiterere y'ibidukikije: Hitamo insinga ikwiye hakurikijwe ubushyuhe, ubushuhe, gutigita n'ibindi bintu by'aho ishyirwa. Urugero, hitamo insinga irinda ubushyuhe bwinshi ku bidukikije bishyuha cyane n'insinga idapfa amazi ku bidukikije bishyuha.

2, hitamo ubwoko bukwiye bw'insinga

Insinga zizungurutse zifite uburinzi: Insinga zizungurutse zifite uburinzi zisabwa gukoreshwa mu nganda nyinshi kugira ngo bigabanye ingaruka mbi z'amashanyarazi n'imivugire.

Insinga zidafite uburinzi: ni mu kirere cy’aho amashanyarazi ahurira n’urumuri, ni ntoya cyane ku buryo insinga zidafite uburinzi zikoresha urumuri.

3, tekereza ku bijyanye no guhuza ibidukikije

Ingano y'ubushyuhe, urwego rw'uburinzi, ukunyeganyega no kudahungabana, kurwanya imiti: hitamo insinga zishobora gukora neza mu buryo buhamye mu buryo nyabwo bwo gukoreshwa.
