IZINDABA ZOKUSEBENZA OKUSEBENZA Ukushintsha izinkinobho ezinezindawo ezine kuphaneli engaphambili ye-Parallel Link Driver Module inquma imodi yokusebenza kwephrosesa. I-620-25/35 ihlanganisa izindlela ezine zokusebenza: PROGRAM, RUN, RUN/PROGRAM. kanye KHUBAZA. INDLELA YOHLELO Isistimu ingase ibekwe kumodi yoHLELO ngokushintsha ukhiye wephaneli yangaphambili. I-Processor Module ayisebenzisi uhlelo lokulawula. I-RUN LED ku-Parallel Link Driver Module (PLDM) IVALIWE lapho isistimu ikumodi yoHLELO. Uma iphrosesa ikumodi ye-PROGRAM, isignali idluliselwa Kusistimu ye-I/O evumela ama-rack e-I/O angawodwana ukuthi akhethwe ukuze amise noma asule okuphumayo. Oxhumana nabo bangase baphoqwe uma i-Force Vuliwe Ukushintshwa (SW2 switch 4) ku-PLDM IVALIWE/VULIWE. Idatha yesibali-sikhathi/ikhawunta egcinwe Kumojuli Yokubhalisa ingase ishintshwe kungakhathaliseki ukuthi isiphi isimo Sokushintsha Kwedatha Vumela Ukushintsha (i-SW2 switch 5) njengoba iphrosesa isivele ikumodi ye-PROGRAM. Ukushintshela ukushintsha okhiye kwenye imodi yokucubungula kususa iphrosesa kumodi ye-PROGRAM. Uma isistimu ibekwe kumodi ye-PROGRAM yi-Loader/Terminal noma i-CIM, isicelo semodi ye-PROGRAM yesofthiwe kufanele sisuswe kusicubungula okubangela ukuthi isistimu ibuyele kumodi yokusebenza ecaciswe indawo yokushintsha ukhiye. INDLELA YOHLELO LOKUSEBENZA Uhlelo lungafakwa Kumodi YoHLELO Lwesofthiwe nguMlayishi/Itheminali noma i-CIM. Isilawuli esihlelekayo kufanele sibe kumodi ethi RUN/PROGRAM noma DISABLE, kanye nomsebenzi wokuhlela oku-inthanethi unikwe amandla ngokuya nge-SW2 switch 6 ku-PLDM. Uhlelo lungena kumodi ye-Software PROGRAM kuphela ngemva kokuthi ukuskena sekuqediwe. Lapho Isilayishi sisusa isicelo Semodi yoHLELO Lwesofthiwe, iphrosesa ishiya imodi ye-PROGRAM yesofthiwe bese ibuyela kumodi yasekuqaleni, ngemva kokuba uhlelo lusisebenzise ngempumelelo ukuskena okubuyiswayo nokuzihlola. Izinguquko zemodi ye-Software PROGRAM zenziwa nge-LOADER/TERMINAL yokushintsha imenyu yokusiza. Lo msebenzi uwusizo ikakhulukazi esigabeni sokususa iphutha sohlelo lwezinguquko ezibanzi. Umsebenzisi angase aqaphe ukusebenza kohlelo, athole iphutha, alishintshe, futhi asebenzise uhlelo kusukela kukhibhodi. RUN MODE Uhlelo lukumodi ethi RUN uma inkinobho yephaneli yangaphambili isendaweni ethi RUN noma RUN/PROGRAM. Imodi ye-RUN iyindlela yokulawula eyinhloko yephrosesa. Isistimu yenza ukuskena okubuyiswayo uma iqala ingena kumodi ye-RUN. Ngesikhathi sokuskena kokugcina konke okuphumayo okungagciniwe kusuka ku-0 kuye ku-4095 KUVALIWE. Imiphumela egciniwe igcina isimo ebikuso ngesikhathi sokuskena kokugcina okwenziwa ngaphambi kokukhishwa kumodi ye-RUN. Ngemuva kokuthi ukuskena okubuyiswayo sekuqediwe, ukuskena kohlelo lomsebenzisi kuqala ngokuqinisekisa ukuthi umyalelo we-Input Status Scan (ISS) utholakala endaweni yenkumbulo yokuqala yohlelo lomsebenzisi. Ngenkathi isimo sokufakwayo siqoqwa ohlelweni lwe-I/O, iphrosesa ihlola ukuphazamiseka kwephutha lekhadi. Uma kutholwa noma yimaphi amaphutha ekhadi ohlelweni lwe-I/O, ulwazi olunephutha lufakwa Kuthebula Lesimo Sesistimu.
