imikhiqizo

9.3 I-PROFIBUS DP Uhlolojikelele I-PROFIBUS DP iyinhloko/isigqila, inethiwekhi yokudlulisa amathokheni, esebenzisa iphrothokholi yesicelo/yempendulo. Imisebenzi yokushintshana kwedatha eyisisekelo iqinisekisa ukuthi ngezikhathi ezithile, inkosi ithumela umlayezo ophumayo esigqileni ngasinye, esiphendula ngokushintshana ngomlayezo wokufaka. I-PROFIBUS DP ivamise ukusetshenziswa njengenethiwekhi ye-I/O. Njengoba kuqhathaniswa nesakhiwo senethiwekhi ye-I/O yendabuko edinga izintambo ezizinikele phakathi kwemojuli ngayinye ye-I/O nedivayisi yesilawuli, i-PROFIBUS inikeza inzuzo yenethiwekhi/ibhasi eyodwa okuhlala kuyo wonke amadivaysi e-I/O e-peripheral. I-Fiber Optic Njengoba isixhumi esibonakalayo se-Experion njengamanje sisebenzisa uxhumano lukagesi, ukusetshenziswa kwe-fiber optic media ngeke kuxoxwe ngakho kulo mbhalo. Kulindeleke nokho ukuthi imikhiqizo ehlukahlukene etholakala ngokwentengiso ingasetshenziswa nohlelo lwe-Experion, oluzovumela ukusetshenziswa kukagesi, kanye ne-fiber optic media kunethiwekhi ye-PROFIBUS DP. I-Bus Wiring (ekagesi) I-PROFIBUS DP isebenzisa i-topology yebhasi "ye-daisy-chain", enentambo ye-PROFIBUS eyodwa exhunywe kunkosi kuya kusigqila sokuqala futhi ngesigqila ngasinye kunethiwekhi. "Amagatsha" angasekelwa ngokusebenzisa izingxenye, ahlukaniswe abaphindaphindayo, abachazwe kafushane ngezansi. Imidiya yokufaka izintambo zikagesi esetshenziselwa i-PROFIBUS iyipheya esontekile evikelekile (amakhondaktha ama-2 kanye nesihlangu). Ikhebula elikhethekile elihlangabezana nohlelo lwe-PROFIBUS liyatholakala ngokwentengiso. Izixhumi ezisetshenziswayo ngokuvamile ziyi-9 pin Sub-D isixhumi, esinamaphinikhodi 3 no-8 asetshenziselwa amasignali edatha amahle/abi. Bheka imidwebo yezintambo zezinto ezisetshenziswayo ukuze uthole imininingwane eyengeziwe. Amadivayisi asekupheleni kwesegimenti ngayinye adinga ukunqanyulwa okusebenzayo, ukujikeleza okuvame ukucaciswa ngesisekelo sedivayisi. Kungenjalo, izixhumi ze-PROFIBUS ezinomjikelezo ohlanganisiwe wokunqamula ziyatholakala ngokwentengiso. Bheka imibhalo yobuchwepheshe yedivayisi ukuze uthole imininingwane eyengeziwe mayelana nezintambo nokunqanyulwa. Amaphrofayili Edivayisi Ngenxa yokuntuleka kwencazelo kusendlalelo sephrezentheshini, i-PROFIBUS Trade Organization (PTO) ichaze isethi yamaphrofayela edivayisi ahlinzeka ngezinga elithile lokumiswa kumadivayisi athile ayinkimbinkimbi. Lawa maphrofayela awayona ingxenye ngokusemthethweni yencazelo yephrothokholi ye-PROFIBUS, ngakho-ke awathathwa njengengxenye yemodeli yokuxhumana ye-PROFIBUS evezwe ngenhla. Nokho, kumadivayisi athile lawa maphrofayela edivayisi ahlinzeka ngezinga elithile lokumiswa kusendlalelo sokuphatha idatha. Qaphela ukuthi abathengisi bedivayisi abadingeki ukuthi basebenzise lawa maphrofayili. Isethi yamaphrofayili atholakalayo ihlanganisa lokhu okulandelayo:  Iphrofayili yokuxhumana phakathi kwabalawuli  Iphrofayili yamadivayisi okulawula inqubo  Iphrofayili yezilawuli ze-NC/RC (amarobhothi)  Iphrofayili yamadrayivu esivinini aguquguqukayo  Iphrofayili yama-Encoder  Iphrofayili yezinhlelo ze-HMI  Iphrofayili yokuphepha
