2. Ukucaciswa Okucacisiwe kwamamojula we-Series-8 I/O kukhonjisiwe ngezansi. 2.1. Okokufaka Kwezinga Eliphansi Le-Analog (Izinga Lokushisa) - Umsebenzi we-LLMUX Imojula ye-LLMUX IOP isekela amashaneli angama-64 okokufaka kwezinga lokushisa. Okokufaka kwezinga eliphansi kusebenzisa i-Honeywell PMIO LLMUX FTA. I-FTA ngayinye isekela iziteshi eziyi-16. Izinhlobo ezimbili ze-LLMUX FTA ziyasekelwa. Eyodwa inikeza okokufaka kwe-RTD okungu-16. Enye inikeza okokufaka okungu-16 TC noma kwe-MV. Noma iyiphi inhlanganisela yama-FTA ingase isetshenziselwe ukuhlinzeka ngenhlanganisela yamaphoyinti e-TC, mV noma e-RTD adingekayo. Izici Eziphawulekayo • Ukusebenza kwe-TC ne-RTD • Amandla okuhlanganisa abandayo akude • Ukuskena kwe-PV yesibili oku-1 ngokuvikelwa kwe-OTD • Ukuvikelwa kwe-OTD Okulungisekayo (Bheka ngezansi) • Amaphuzu okushisa angengezwa ngamaphoyinti angu-16 akhuphukayo Usekelo Lwezinga Lokushisa Okokufaka Kwezinga lokushisa I-LLMUX isekela isimo esikhona esiqinile se-PMIO LLMUX FTA. I-PMIO LLMUX FTA isekela okokufaka kwe-RTD kanye ne-Thermocouple (TC). Ukushintshashintsha kwezinga lokushisa kuqoqwa kuwo wonke amaphuzu ngesilinganiso esingu-1 sesekhondi. Ukubuyekezwa kwesekhondi elingu-1 kufaka phakathi isheke elilungisekayo le-Open Thermocouple Detection (OTD) (bona ngezansi) ngaphambi kokusatshalaliswa kokuhlukahluka kwezinga lokushisa. Konke okokufaka kwe-TC kunxeshezelwa kusetshenziswa idivayisi ye-Cold Junction Compensation (CJT). Isampula ne-Open Sensor Thola I-Temperature multiplexer isekela i-RTD kanye ne-Thermocouples Nge-Open Sensor Detect ngaphambi kokuba i-PV ilethwe uma imisiwe. Njengoba ukulungiselelwa kwe-OTD kusebenza, i-PV ithathwa njengesampula futhi ibanjwe ngenkathi umjikelezo we-OTD wenziwa ngaphakathi kwewindi lokulinganisa elifanayo. Uma i-OTD inegethivu, i-PV isakazwa ngesistimu. Uma i-OTD ivuma, i-PV isethelwe ku-NAN futhi ukwehluleka okuthambile kweshaneli yokufaka kusethiwe. Ngale ndlela, asikho isenzo sokulawula esingalungile esenzeka kumanani e-PV angavumelekile ngenxa ye-thermocouple evulekile. Ukusampula/ukubika kwe-PV akulethi ukubambezeleka okwengeziwe kusukela ekucutshungulweni kwe-OTD.
