Mokhoa oa ho Lekola Tshebetso le Botšepehi ba Likhoele tsa PROFINET?

1. Ke Hobane'ng ha ho Leka Lithapo tsa PROFINET ho le Bohlokoa

PROFINET ke maemo a Ethernet a liindasteri a amoheloang ka bongata a lumellang puisano ea nako ea nnete lipakeng tsa lisebelisoa libakeng tsa tlhahiso. Ha mekhatlo e ntse e tsoela pele ho itšetleha ka thekenoloji ena ho matlafatsa khokahanyo le mekhoa e metle, bohlokoa ba ho netefatsa hore boleng le ts'ebetso ea lithapo tsa PROFINET li ke ke tsa fetisoa. Ho lekola likhoele tsena ha se feela mokhoa oa ho thibela - ke mohato oa bohlokoa oa ho sireletsa lisebelisoa tsohle tsa marang-rang.

Ho lekola likhoele tsa PROFINET ho netefatsa melemo e mene e meholo:

1. Phetiso ea data e tsitsitsengka ho thibela tahlehelo ea liphutheloana le mefokolo ea puisano.

2. Botšepehi ba marang-rang, ho fokotsa nako e sa lebelloang ea ho theoha.

3. Ho latela litekanyetso, e netefatsang ho khomarela litlhoko tsa IEC 61158 le PROFINET.

4. Ho boloka litšenyeheloka ho lemoha liphoso pele li fetela ho hloleha ha sistimi.

2. Lintlha tsa Ts'ebetso ea Bohlokoa ho Lekoa

Ha u leka lithapo tsa PROFINET, lintlha tse latelang li lokela ho hlahlojoa:

• Botšepehi ba lets'oao– e netefatsa phetiso e hloekileng, e se nang khopamo ea data.

• Tšitiso ea boiphetetso- PROFINET hangata e hloka 100Ω Cat5e/Cat6 cabling.

• Crosstalk (E LATELANG le FEXT)- e thibela tšitiso lipakeng tsa li-cable pair.

• Khatholoho- e lekanya tahlehelo ea lets'oao ho feta bolelele ba cable.

• Khutlisetsa tahlehelo- e lekola maikutlo a bakoang ke ho felloa ke nako hantle.

• Tšireletso e sebetsang hantle- ea bohlokoa maemong a lerata a indasteri.

• Tšenyo 'meleng- ho khaola, ho khumama, kapa kinks ho ka theola ts'ebetso.

Mohlala oa cable:
PROFINET mofuta oa B/C oa indasteri Cat5e Ethernet cable, IP67-rated D-coded M12 e motona ho ea ho mosali, SF/UTP e sirelelitsoeng habeli 22AWG li-conductors, boemo bo phahameng ba indasteri ea kantle, PLTC e lekantsoe, baki ea TPE e tala.

3. Mekhoa ea ho Lekola Lithapo tsa PROFINET

1) Tlhahlobo ea Pono

Tlhahlobo e phethahetseng ea pono ke mohato oa pele oa ho hlahloba botšepehi ba cable. Sheba lihokelo tsohle bakeng sa matšoao a tšenyo, kutu, kapa lithakhisa tse kobehileng. Lekola bolelele ba thapo bakeng sa khatello ea maikutlo, ho kobeha ho tiileng, kapa tšireletso e pepeneneng. Ka kakaretso, boloka sebaka se fokolang sa ho koba se lekanang le bophara ba cable ka makhetlo a robeli ho thibela tšenyo e ka hare ea conductor.

2) Teko ea Tsoelo-pele

Teko ea ho tsoela pele e netefatsa hore li-conductors tsohle tse robeli li hokahane hantle ho tloha qetellong. Sena se supa li-circuits tse bulehileng, marikhoe a makhutšoane kapa lithapo tse tšelang tse ka sitisang puisano. Sesebelisoa se bonolo sa cable tester kapa multimeter se ka netefatsa tsoelo-pele ea mantlha nakong ea licheke tsa ho kenya kapa tsa tlhokomelo.

3) Teko ea Wiremap

Teko ea Wiremap e netefatsa likabelo tse nepahetseng tsa phini ho latela maemo a TIA-568A kapa TIA-568B. E supa lipara tse arohaneng tse ka 'nang tsa se hlahe tekong ea ho tsoelapele empa li ka senya boleng ba matšoao haholo. Ho netefatsa sebopeho sa wiring ho thusa ho boloka ts'ebetso e tsitsitseng le ho latela maemo.

4) Tlhahlobo ea Botšepehi ba Letšoao

Teko ea ponts'o ea mats'oao e lekola bokhoni ba thapo ea ho fetisa data ntle le ho senyeha ka ho lekanya ho fokotseha, ho fetella le ho sitisa. Lisebelisoa tse kang Fluke Networks DSX CableAnalyzer hangata li sebelisetsoa ho netefatsa lithapo bakeng sa ho latela litekanyetso tsa ts'ebetso tsa Ethernet le PROFINET.

5) Tšireletso le ho Fana ka Tiiso

Teko ena e tiisa hore ts'ireletso e tsoela pele ho pholletsa le thapo le likhokahano, 'me e supa mathata a motheo a ka eketsang ts'oaetso ho EMI. Ho sireletsa le ho thea fatše ho bohlokoa libakeng tse lerata tsa indasteri.

6) Teko ea Sekhahla sa Phoso ea Bit (BERT)

BERT e lekanya liphoso tsa phetisetso ea data ea nnete tlas'a mojaro. Ka ho lekola litekanyetso tsa liphoso tse nyane nakong ea ts'ebetso, tlhahlobo ena e fana ka tlhahlobo ea 'nete ea ts'ebetso ea cable ts'ebelisong ea lefats'e ea nnete-e bohlokoa bakeng sa marang-rang a hlokang ho ts'epahala ho hoholo le latency e tlase.

7) Teko ea Khatello ea Tikoloho

Teko ea tikoloho e pepesetsa likhoele mochesong o feteletseng, ho thothomela, mongobo le maemo a mang a thata ho netefatsa ho tšoarella libakeng tsa indasteri kapa tsa kantle. Likhoele tsa PROFINET tse nang le maemo a kantle hangata li sebelisa lijakete tsa PUR kapa PE ho hanela mahlaseli a UV le ho pepesehela lik'hemik'hale.

Mohlala oa cable:
Thapo ea PROFINET ea mofuta oa B/C ea indasteri ea Cat5e Ethernet, e nang le khoutu ea D ea M12 e nang le tekanyo ea IP67, li-conductor tse sirelelitsoeng habeli tsa SF/UTP tse 22AWG, tsa boemo bo phahameng ba kantle, tse nang le tekanyo ea PLTC, jase e tala ea TPE.

4. Lisebelisoa tsa Teko tse khothalelitsoeng

Mehato e fapaneng ea lisebelisoa tsa tlhahlobo e netefatsa botšepehi ba cable ea PROFINET le ho latela:

• Bahlahlobi ba motheo- Bakeng sa tsoelo-pele e potlakileng le licheke tsa wiremap.

• Bahlahlobi ba setifikeiti ba tsoetseng pele (mohlala, Fluke, Softing)- Netefatsa ho latela melao ea PROFINET le Ethernet ka ho lekanya ho nyenyefatsa, ho fetelletsa litaba, ho sitisa, le tse ling.

• Bahlahlobisisi ba marang-rang- Lekola ts'ebetso ea marang-rang ea nako ea nnete, hlokomela boleng ba puisano, 'me u bone litaba tsa ts'ebetso.

5. Litlhahiso tsa Tlhahlobo e Tšepahalang

• Kamehla leka pele u kenya ho qoba nako e theko e boima le ho sebetsa hape.

• Ngola lithapo tsohle tse lekiloeng le litlaleho tsa setifikeiti sa lebenkele bakeng sa ho hlaka nakong ea lihlahlobo kapa tlhokomelo.

• Sebelisa likhokahano tse sirelelitsoeng libakeng tse phahameng tsa EMI ho boloka botšepehi ba matšoao.

• Kenya sebaka sa mohala ofe kapa ofe ka tahlehelo ea matšoao e fetang meeli e tloaelehileng (mohlala,> 3 dB) ho netefatsa ts'epo ea nako e telele ea marang-rang.

6. Liphoso Tse Tloaelehileng Tsa ho Etsa liteko tseo u lokelang ho li Qoba

Liphoso tse tloaelehileng tse sitisang ho nepahala ha liteko li kenyelletsa:

• Ho tlola netefatso ea tšireletso libakeng tse nang le maemo a holimo a leholimo.

• Ho itšetleha ka bahlahlobi ba maemo a bareki ho fapana le lisebelisoa tse netefalitsoeng ke PROFINET.

• Ho iphapanyetsa litataiso tsa ho kenya moetsi.

• Ho hloleha ho lekola likhoele tlas'a mojaro oa 'nete, ho thibela ho lemoha litaba tsa ts'ebetso tse etsahalang feela nakong ea ts'ebetso.

7. Litlhahiso tsa ho Tšepahala ha nako e telele

• Sebelisa Cat6 kapa lithapo tsa boleng bo holimo tsa PROFINET bakeng sa lisebelisoa tsohle tse ncha.

• Theha moralo oa tlhokomelo ea thibelo ka tlhahlobo ea cable ea nako le nako ho bona ho senyeha ha pele.

• Khetha lithapo tsa LSZH kapa PUR-jacket bakeng sa tikoloho e thata kapa e boima.

• Boloka le ho tšoara lithapo hantle, ho qoba ho kobeha ho feteletseng kapa khatello ea mochine ho thibela mapetsong a manyenyane a senyang tšebetso ea motlakase ha nako e ntse e ea.

8. Lipotso Tse Botsoang Khafetsa Mabapi le Teko ea Cable ea PROFINET

P1: Likhoele tsa PROFINET li lokela ho lekoa hangata hakae?
A: Teko nakong ea ho kenya le likhoeli tse ling le tse ling tse 12-18 e le karolo ea tlhokomelo ea thibelo.

Q2: Na liteko tse tloaelehileng tsa Ethernet li ka sebelisoa bakeng sa likhoele tsa PROFINET?
A: Ba ka etsa liteko tsa mantlha, empa bahlahlobi ba netefalitsoeng ba PROFINET ba khothaletsoa hore ba tšepahale ka botlalo.

Q3: Ke bolelele bofe ba cable bo tšehetsoeng bakeng sa PROFINET?
A: limithara tse 100 ka karolo ka 'ngoe bakeng sa likhoele tsa koporo; fiber-optic PROFINET e ka atolosa hole.

Q4: Nka netefatsa joang hore ho sireletsa ho sebetsa?
A: Ka ho etsa ts'ebetso ea ts'ireletso le liteko tsa motheo.

Q5: Na ho lekola likhoele tsa ka ntle tsa PROFINET li fapane?
A: Ho joalo. Ntle le liteko tsa motlakase, khanyetso ea UV, mamello ea mocheso le ts'ireletso ea mongobo le tsona lia hlahlojoa.
