Product Overview

I-Trusted® Communications Interface (CI) yimodyuli ekrelekrele ebonelela ngoluhlu lweenkonzo zonxibelelwano kuMlawuli othembekileyo, ukunciphisa ukulayishwa konxibelelwano lwe-Triple Modular Redundant (TMR) Processor. Imodyuli elungiselelwe ngumsebenzisi, i-CI inokuxhasa imidiya yonxibelelwano emininzi. Ukuya kuthi ga kwiiNxibelelwano zoNxibelelwano ezine (CIs) zinokuxhaswa yiNkqubo ethembekileyo.

Iimbonakalo:

• Inkqubo yokuSebenza ethembekileyo. • I-Ethernet ephindwe kabini kunye nezibuko ezine ezilandelelanayo. • Inkxaso yoluhlu olubanzi lwemigaqo yonxibelelwano. • Ukhuseleko, unxibelelwano oluthembekileyo ngokusebenzisa amakhonkco onxibelelwano olusebenza kakhulu. • Ikhoboka leModbus. • Ukuzikhethela kweModbus Master (ene-T812X Trusted Processor Interface Adapter). • Ulandelelwano loKhetho lweMisitho (SOE) Ngaphezu kwe-Modbus. • I-Front Panel serial diagnostic port, fault and status indicators.

1.3. Isishwankathelo

I-CI eThenjiweyo ibonelela ngeNkqubo eThenjiweyo ngeNxibelelwano yoNxibelelwano olukrelekrele, esebenza njenge-relay phakathi kweProsesa, ezinye iiNkqubo eziThenjiweyo, i-Engineering Workstation kunye nezixhobo zeqela lesithathu.

1.3.1. Hardware

Imodyuli ineMotorola Power PC Processor. Isoftware ye-Bootstrap igcinwe kwi-Erasable Programmable Read only Memory (EPROM). I-firmware esebenzayo igcinwe kwimemori ye-flash kwaye inokuphuculwa nge-Front Panel Port. Inkqubo yokuSebenza eThenjiweyo isetyenziswa kuzo zombini iProsesa yeTMR kunye neCI. I-kernel yexesha langempela sisantya esiphezulu, i-kernel ephezulu yokusebenza eyenzelwe iinkqubo ezisasazwayo zokunyamezela iimpazamo. I-kernel inikezela ngeenkonzo ezisisiseko (ezifana nolawulo lwememori) kunye nokuphazamiseka kwemekobume zesoftware. I-module watchdog ibeka iliso ekusebenzeni kweprosesa kunye neyunithi yokubonelela ngombane (PSU) imveliso yombane. Imodyuli ibonelelwa nge-dual redundant +24 Vdc feed power from the chassis backplane. Iyunithi yonikezelo lwamandla ebhodini ibonelela ngokuguqulwa kwamandla ombane, ukulungiswa kokubonelela kunye nokukhusela. I-CI eThenjiweyo inxibelelana ne-Trusted TMR Processor nge-triplicated InterModule Bus. Xa iphononongwa yi-Trusted TMR Processor, ujongano lwebhasi yemodyuli ivota idatha yesi-2 kwi-3 (2oo3) ukusuka kwi-Inter-Module Bus kwaye ithumela impendulo yayo ngazo zontathu iindlela ze-Inter-Module Bus. Intsalela yesiNxibelelwano soNxibelelwano ilula. Zonke ii-transceivers zonxibelelwano zihlukaniswe ngombane omnye komnye kunye nemodyuli kwaye zinemilinganiselo eyongezelelweyo yokukhusela okwethutyana. Ubonelelo lwangaphakathi lwemodyuli lubekwe lodwa kwi-dual 24 Vdc feeds.

1.3.2. Unxibelelwano

I-Ethernet Media Access Control (MAC) uqwalaselo lwedilesi lubanjwe yi-CI njengenxalenye yolwazi lwayo lokucwangcisa. Olunye ulwazi malunga nezibuko kunye noqwalaselo lweprothokholi lufunyenwe kwiProsesa yeTMR, njengenxalenye yefayile yeSistim.INI. Idatha ikhutshelwa phakathi kweProsesa yeTMR kunye noNxibelelwano lweNdibaniselwano kusetyenziswa ujongano oluqhelekileyo olubizwa ngokuba nguMphathi oGuquguqukayo weNethiwekhi. Xa idatha ifundwa kwiNkqubo ethembekileyo, idatha ifunyenwe kwikopi yendawo egcinwe kwiNxibelelwano yoNxibelelwano, inika impendulo ngokukhawuleza. Idatha ibhala inzima ngakumbi. Ukuba idatha ibhala ihlaziywe nje ikopi yasekhaya kwaye emva koko yathunyelwa kumqhubekekisi, ezinye iiNdibaniselwano zoNxibelelwano kwinkqubo ziya kuthwala idatha eyahlukileyo. Oku kunokubangela iingxaki kwiikhonkco ezingafunekiyo. Ukuze unqobe le ngxaki, xa idatha ibhaliwe kwiNxibelelwano yoNxibelelwano, idluliselwa kuqala kwiProsesa yeTMR kwaye ukubhala kuvunywe ngokukhawuleza kwiNxibelelwano yoNxibelelwano (ukuphepha ukulibaziseka konxibelelwano). Iprosesa ihlaziya idatabase yayo kwaye emva koko ithumela idatha kuzo zonke iiNxibelelwano zoNxibelelwano ukuze zonke zibe nedatha efanayo. Oku kungathatha isicelo esinye okanye ezimbini zokuskena. Oku kuthetha ukuba ukufundwa okulandelayo kuya kufumana idatha endala ngokukhawuleza emva kokubhala, de kube idatha entsha isasazwe. Zonke iinguqu kwi-CI .INI iiparamitha zingalayishwa kwi-intanethi kwaye ziya kusebenza ngokukhawuleza; isiNxibelelwano soNxibelelwano luqhawula lonke unxibelelwano luze luqalise kwakhona. Unxibelelwano luphinda luqaliswe kuhlaziyo lwe-intanethi yesicelo kwaye luyavalwa xa usetyenziso luyekisiwe.
