IsishwankatheloIsetyenziselwa ukudibanisa i-PROFIBUS iinqununu kwintambo yebhasi ye-PROFIBUS Ufakelo olulula
Iiplagi zeFastConnect ziqinisekisa amaxesha amafutshane kakhulu endibano ngenxa yetekhnoloji yokufuduka
I-resistors edibeneyo yokuphelisa (kungekhona kwimeko ye-6ES7972-0BA30-0XA0)
Iziqhagamshelo ezineesokethi ze-D-sub zivumela uqhagamshelo lwe-PG ngaphandle kofakelo olongezelelweyo lweenodi zenethiwekhi
Isicelo
Izixhumi zebhasi ze-RS485 ze-PROFIBUS zisetyenziselwa ukuqhagamshela iindawo ze-PROFIBUS okanye iinxalenye zenethiwekhi ze-PROFIBUS kwintambo yebhasi ye-PROFIBUS.
Yila
Iinguqulelo ezininzi ezahlukeneyo zesiqhagamshelo sebhasi ziyafumaneka, nganye ilungiselelwe izixhobo eziza kudityaniswa:
Isidibanisi sebhasi esine-axial cable outlet (180 °), umz. iiPC kunye nee-SIMATIC HMI OPs, kumazinga othumelo ukuya kuthi ga kwi-12 Mbps kunye ne-resistor edibeneyo yokuphelisa ibhasi.
Isinxibelelanisi sebhasi esinentambo ethe nkqo yokuphuma (90°);
Esi sidibanisi sivumela intambo yokuphuma ethe nkqo (enonxibelelwano lwePG okanye ngaphandle kwayo) kumazinga othumelo ukuya kuthi ga kwi-12 Mbps kunye nesixhasi sokuphelisa ibhasi. Kwizinga lokudluliselwa kwe-3, i-6 okanye i-12 Mbps, i-SIMATIC S5 / S7 i-plug-in cable iyadingeka ukudibanisa phakathi kwekhonkco yebhasi kunye ne-PG-interface kunye nesixhobo sokucwangcisa.
Isidibanisi sebhasi esine-30 ° yokuphuma kwentambo (uguqulelo oluphantsi kwexabiso eliphantsi) ngaphandle kojongano lwePG kumazinga othumelo ukuya kuthi ga kwi-1.5 Mbps kwaye ngaphandle kwebhasi edibeneyo yokuphelisa isixhasi.
I-PROFIBUS FastConnect isinxibelelanisi sebhasi RS 485 (90 ° okanye 180 ° intambo yokuphuma) kunye namazinga othumelo ukuya kuthi ga kwi-12 Mbps yokudityaniswa ngokukhawuleza nangokulula usebenzisa itekhnoloji yoqhagamshelo lwe-insulation displacement (kwiingcingo eziqinileyo neziguquguqukayo).
Umsebenzi
Ikhonkco yebhasi ifakwe ngqo kwi-interface ye-PROFIBUS (i-9-pin Sub-D socket) yesikhululo se-PROFIBUS okanye icandelo lenethiwekhi ye-PROFIBUS.
Intambo ye-PROFIBUS engenayo nephumayo iqhagamshelwe kwiplagi isebenzisa ii-terminals ezi-4.
Ngokusebenzisa ukutshintshwa okufikeleleka ngokulula kubonakala ngokucacileyo ngaphandle, i-terminator yomgca edibeneyo kwikhonkco yebhasi inokudibaniswa (kungekhona kwimeko ye-6ES7 972-0BA30-0XA0). Kule nkqubo, iintambo zebhasi ezingenayo neziphumayo kwikhonkco ziyahlukana (umsebenzi wokwahlula).
Oku kufuneka kwenziwe kuzo zozibini iziphelo zecandelo le-PROFIBUS.
