Isishwankathelo
Isetyenziselwa 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.
