iimveliso

9.3 I-PROFIBUS DP Isishwankathelo IPROFIBUS DP yinkosi/ikhoboka, itoken passing network, esebenzisa inkqubo yesicelo/yempendulo. Imisebenzi yokutshintshiselana ngedatha esisiseko iqinisekisa ukuba ngamaxesha athile, inkosi ithumela umyalezo ophumayo kwikhoboka ngalinye, eliphendula ngokulandelelanayo ngomyalezo wegalelo. IPROFIBUS DP idla ngokusetyenziswa njengenethiwekhi ye-I/O. Njengoko kuthelekiswa ne-architecture ye-I / O yenethiwekhi yendabuko efuna i-wiring ezinikeleyo phakathi kwemodyuli nganye ye-I / O kunye nesixhobo somlawuli, i-PROFIBUS inikeza inzuzo yenethiwekhi enye / ibhasi apho zonke izixhobo ze-peripheral ze-I / O zihlala khona. I-Fiber Optic Ekubeni i-interface ebonakalayo kwi-Experion isebenzisa uxhulumaniso lombane ngoku, ukusetyenziswa kwe-fiber optic media akuyi kuxoxwa kolu xwebhu. Kulindeleke nangona kunjalo ukuba iimveliso ezahlukeneyo ezithengiswayo zinokusetyenziswa kunye nenkqubo ye-Experion, eya kuvumela ukusetyenziswa kombane, kunye ne-fiber optic media kwinethiwekhi ye-PROFIBUS DP. I-Bus Wiring (yombane) I-PROFIBUS DP isebenzisa i-"daisy-chain" i-topology yebhasi, kunye nentambo enye ye-PROFIBUS exhunywe kwi-master ukuya kwikhoboka lokuqala kunye nekhoboka ngalinye kuthungelwano. "Amasebe" anokuxhaswa ngokusetyenziswa kwamacandelo, ahlukaniswe ngabaphindaphindayo, achazwe ngokufutshane apha ngezantsi. Usasazo lweengcingo zombane olusetyenziselwa iPROFIBUS lukhuselo olujijekileyo iperi (iikhondaktha ezi-2 kunye nekhaka). Intambo ekhethekileyo edibana nesicelo sePROFIBUS iyafumaneka ngokurhweba. Izixhumi ezisetyenzisiweyo ngokuqhelekileyo ziyi-9 pin Sub-D ikhonkco, kunye nezikhonkwane ze-3 kunye ne-8 ezisetyenziselwa iimpawu zedatha ezilungileyo / ezimbi. Jonga kwimizobo yocingo yesixhobo esisetyenziswayo kwiinkcukacha ezongezelelweyo. Izixhobo ezisekupheleni kwecandelo ngalinye zifuna ukupheliswa okusebenzayo, i-circuitry echazwe ngokubanzi kwisiseko se-perdevice. Ngenye indlela, i-PROFIBUS izixhumi ezinesekethe edibeneyo yokuphelisa ziyafumaneka ngokurhweba. Jonga kumaxwebhu obugcisa besixhobo ukuze ufumane iinkcukacha ezongezelelweyo malunga nocingo kunye nokupheliswa. Iiprofayili zeSixhobo Ngenxa yokunqongophala kwengcaciso kuleko lwenkcazo-ntetho, iPROFIBUS Trade Organisation (PTO) ichaze iseti yeeprofayili zesixhobo ezibonelela ngenqanaba elithile lokumiselwa komgangatho wezixhobo ezithile ezinzima. Ezi profayili aziyonxalenye ngokusesikweni yenkcazo yeprotocol ye-PROFIBUS, ngoko ke azithathwa njengenxalenye yemodeli yonxibelelwano ye-PROFIBUS eboniswe ngasentla. Nangona kunjalo, kwizixhobo ezithile ezi nkcukacha zesixhobo zibonelela ngeqondo elithile lokumiselwa komgangatho kuluhlu lolawulo lwedatha. Qaphela ukuba abathengisi besixhobo abanyanzelekanga ukuba basebenzise ezi profayili. Isethi yeeprofayili ezikhoyo zibandakanya oku kulandelayo:  Iprofayili yonxibelelwano phakathi kwabalawuli  Iprofayili yezixhobo zolawulo lwenkqubo  Iprofayili ye-NC/RC controllers (robhothi)  Iprofayili yee-variable speed drives  Iprofayili yee-Encoders  Iprofayili yeesistim ze-HMI  Iprofayili yokhuseleko.
