Ithebula A-2: RS422/485 Isifinyezo sokucaciswa
Ukuze uvimbele ukubonakaliswa kwesignali kukhebula nokuthuthukisa ukwenqatshwa komsindo kuyo yomibili imodi ye-RS422 kanye ne-RS485, isiphetho somamukeli wekhebula kufanele sinqanyulwe ngokumelana okulingana nesici sekhebuli. (Okuhlukile kulokhu kuyisimo lapho ulayini ushayelwa khona umshayeli we-RS422 ongalokothi “anqunywe kathathu” noma anqanyulwe emugqeni. Kulokhu, umshayeli uhlinzeka ngokuvimba okuphansi kwangaphakathi okunqamula umugqa ngaleso sikhathi.)

Qaphela
Akudingeki ukuthi wengeze isinqamuleli ezintamboni zakho uma usebenzisa i-adaptha. Izinqamuli zokunqamula imigqa ye-RX+ ne-RX- zinikezwa ekhadini futhi zibekwe kumjikelezo lapho ufaka ama-RS 485 jumper. (Bheka ingxenye ethi Inketho Yokukhetha yaleli bhukwana.)

RS485 Data Transmission
I-RS485 Standard ivumela ulayini wokudlulisela olinganiselayo ukuthi wabelane ngemodi yeqembu leqembu. Amaphesenti angaba ngu-32 abashayeli/abamukeli angabelana ngenethiwekhi yomugqa wezinhlangothi ezimbili. Izici eziningi zabashayeli nabamukeli ziyafana neziku-RS422 Standard. Omunye umehluko ukuthi imodi evamile voltagUmkhawulo we-e unwetshiwe futhi ungu-+12V ukuya ku-7V. Njengoba noma yimuphi umshayeli enganqanyulwa (noma aphindwe kathathu) emugqeni, kufanele amelane nale modi evamile voltage ububanzi ngenkathi isesimweni se-tristate.
Umfanekiso olandelayo ubonisa inethiwekhi evamile ye-multidrop noma yephathi. Qaphela ukuthi ulayini wokudlulisela unqanyuliwe kuzo zombili iziphetho zomugqa kodwa hhayi ezindaweni zokulahla phakathi nomugqa.

I-RS485 Inethiwekhi Yezintambo Ezine Multidrop
Inethiwekhi ye-RS485 nayo ingaxhunywa ngemodi enezintambo ezine. Kunethiwekhi enezintambo ezine kuyadingeka ukuthi i-node eyodwa ibe yi-master node futhi bonke abanye babe yizigqila. Inethiwekhi ixhunywe ukuze inkosi idlulisele kuzo zonke izigqila futhi zonke izigqila zidlulisela enkosini. Lokhu kune-advantages kumishini esebenzisa ukuxhumana kwephrothokholi okuxubile. Njengoba izikhala zesigqila zingalokothi zilalele impendulo yesinye isigqila enkosini, indawo yesigqila ayikwazi ukuphendula ngokungalungile.

Iwaranti

Ngaphambi kokuthunyelwa, imishini ye-ACCES ihlolwa ngokucophelela futhi ihlolwe ngokwemininingwane esebenzayo. Kodwa-ke, uma kwenzeka ukungasebenzi kwemishini kwenzeka, i-ACCES iqinisekisa amakhasimende ayo ukuthi isevisi esheshayo nokusekelwa kuzotholakala. Zonke izinto zokusebenza ezakhiwe yi-ACCES okutholwe ukuthi zinephutha zizokhandwa noma zishintshwe kuncike kulokhu okulandelayo.

Imibandela
Uma iyunithi isolwa ngokwehluleka, xhumana nomnyango Wesevisi Yamakhasimende we-ACCES. Zilungiselele ukunikeza inombolo yemodeli yeyunithi, inombolo ye-serial, kanye nencazelo yezimpawu zokwehluleka. Singase siphakamise ukuhlola okulula ukuze siqinisekise ukwehluleka. Sizonikeza inombolo ye-Return Material Authorization (RMA) okufanele ivele kulebula yangaphandle yephakheji yokubuyisela. Wonke amayunithi/izingxenye kufanele zipakishwe ngendlela efanele ukuze ziphathwe futhi zibuyiswe nempahla ekhokhelwe kusengaphambili Esikhungweni Sesevisi esiqokiwe se-ACCES, futhi izobuyiselwa endaweni yekhasimende/indawo yomsebenzisi ekhokhelwa kusengaphambili kanye ne-invoyisi.

Ukuhlanganisa
Iminyaka Emithathu Yokuqala: Iyunithi/ingxenye ebuyiselwe izolungiswa futhi/noma ithathelwe indawo ngokhetho lwe-ACCES ngaphandle kwenkokhiso yomsebenzi noma izingxenye ezingafakwanga ngaphandle kwewaranti. Iwaranti iqala ngokuthunyelwa kwemishini.
Iminyaka Elandelayo: Kuso sonke isikhathi sokuphila kwemishini yakho, i-ACCES ime ngomumo ukuhlinzeka ngensizakalo esizeni noma esitshalweni ngamanani afanelekile afana nawabanye abakhiqizi embonini.

Izisetshenziswa ezingakhiqiziwe yi-ACCES
Izisetshenziswa ezihlinzekiwe kodwa ezingakhiqiziwe yi-ACCES ziqinisekisiwe futhi zizokhandwa ngokuvumelana nemigomo nemibandela yewaranti yomkhiqizi wezisetshenziswa ezifanele.

Okujwayelekile
Ngaphansi kwalesi Siqiniseko, isikweletu se-ACCES sikhawulelwe ekushintsheni, ekulungiseni noma ekukhipheni isikweletu (ngokubona kwe-ACCES) sanoma yimiphi imikhiqizo okubonakale sengathi ayinasici ngesikhathi sewaranti. Akunjalo uma i-ACCES inesibopho sokulimala okulandelanayo noma okukhethekile okuvela ekusebenziseni noma ukusetshenziswa kabi komkhiqizo wethu. Ikhasimende linesibopho sazo zonke izinkokhiso ezibangelwa ukuguqulwa noma ukwengezwa kwempahla ye-ACCES engagunyazwanga ngokubhaliwe i-ACCES noma, uma ngokombono we-ACCES okokusebenza kusetshenziswe ngendlela engavamile. “Ukusetshenziswa okungavamile” ngokwezinjongo zalesi siqinisekiso kuchazwa njenganoma yikuphi ukusetshenziswa okuvezwe kukho ngaphandle kwalokho okushiwo noma okuhlosiwe njengoba kufakazelwa ngokuthengwa noma ukumelwa kokuthengisa. Ngaphandle kwalokhu okungenhla, asikho esinye iwaranti, esiveziwe noma esishiwo, esiyosebenza kunoma iyiphi kanye nazo zonke izinto ezinjalo ezihlinzekwe noma ezithengiswa yi-ACCES.
