2. IiNkcazelo zeNgcaciso zeemodyuli ze-Series-8 I / O ziboniswe ngezantsi. 2.1. Igalelo leNqanaba eliPhantsi le-Analog (Ubushushu) - Umsebenzi weLLMUX Imodyuli ye-LLMUX IOP ixhasa ukuya kuthi ga kwiitshaneli ezingama-64 zamagalelo obushushu. Amagalelo asezantsi asebenzisa i-Honeywell PMIO LLMUX FTA. I-FTA nganye ixhasa amajelo ali-16. Iintlobo ezimbini zeLLMUX FTA ziyaxhaswa. Enye ibonelela ngamagalelo e-RTD ali-16. Enye ibonelela nge-16 TC okanye i-MV inputs. Nayiphi na indibaniselwano yee-FTAs ingasetyenziselwa ukubonelela ngomxube we-TC, mV okanye amanqaku e-RTD afunekayo. Iimpawu eziqaphelekayo • Ukusebenza kwe-TC kunye ne-RTD • Ukukwazi ukudityaniswa okukude okubanda • Ukuskena kwe-PV yesiBini ye-1 ngokhuseleko lwe-OTD • Ukhuseleko lwe-OTD olulungisekayo (Jonga ngezantsi) • Amanqaku obushushu angongezwa ngeengongoma ezili-16 zokunyuswa koBubushushu Igalelo loBubushushu iLLMUX ixhasa imeko ekhoyo eqinileyo ye-PMIO LLMUX FTA. I-PMIO LLMUX FTA ixhasa i-RTD kunye ne-Thermocouple (TC) igalelo. Ukutshintsha kweqondo lokushisa kuqokelelwa kuwo onke amanqaku kwinqanaba le-1 yesibini. Uhlaziyo lwesibini lwe-1 lubandakanya isheke esilungelelanisiweyo se-Open Thermocouple Detection (OTD) (jonga ngezantsi) ngaphambi kokusasazwa kokutshintsha kweqondo lokushisa. Onke amagalelo eTC abuyekezwa kusetyenziswa isixhobo seCold Junction Compensation (CJT). Isampulu kunye neSensor evulekileyo yokubona i-Temperature multiplexer ixhasa i-RTD kunye ne-Thermocouples nge-Open Sensor yokubona phambi kokuba i-PV isiwe ukuba iqwalaselwe njalo. Ngoqwalaselo lwe-OTD olusebenzayo, i-PV isampula kwaye ibanjwe ngelixa umjikelo we-OTD wenziwa ngaphakathi kwefestile yomlinganiselo ofanayo. Ukuba i-OTD ayinayo, i-PV isasazwa ngenkqubo. Ukuba i-OTD ilungile, i-PV imiselwe kwi-NAN kwaye ukusilela okuthambileyo kwetshaneli kusetyenzisiwe. Ngale ndlela, akukho ntshukumo yolawulo engafanelekanga eyenzekayo kumaxabiso e-PV angasebenziyo ngenxa ye-thermocouple evulekileyo. Isampulu ye-PV/ukunika ingxelo akubanga kulibaziseka okongeziweyo ukusuka kuqhubekeko lwe-OTD.
