Product Overview

Lub Trusted® Communications Interface (CI) yog ib qho kev txawj ntse uas muab ntau yam kev pabcuam kev sib txuas lus rau Trusted Controller, txo qis kev sib txuas lus ntawm Triple Modular Redundant (TMR) Processor. Tus neeg siv-configurable module, CI tuaj yeem txhawb nqa ntau yam kev sib txuas lus. Txog li plaub qhov Kev Sib Txuas Lus Sib Txuas (CIs) tuaj yeem txhawb nqa los ntawm Trusted System.

Nta:

• Trusted Operating System. • Dual Ethernet thiab plaub qhov chaw nres nkoj. • Txhawb rau ntau yam kev sib txuas lus raws tu qauv. • Kev ruaj ntseg, kev sib txuas lus tau zoo los ntawm kev sib txuas lus zoo. • Modbus qhev. • Xaiv Modbus Master (nrog T812X Trusted Processor Interface Adapter). • Kev Xaiv Ib Ntus Ntawm Cov Txheej Txheem (SOE) Tshaj Modbus. • Pem hauv ntej vaj huam sib luag serial diagnostic chaw nres nkoj, txhaum thiab cov xwm txheej ntsuas.

1.3. Txheej txheem cej luam

Lub Trusted CI muab cov Trusted System nrog kev sib txuas lus ntse ntse, ua haujlwm ntawm kev sib txuas ntawm cov txheej txheem, lwm cov Trusted Systems, Engineering Workstation thiab cov cuab yeej thib peb.

1.3.1. Kho vajtse

Lub module muaj Motorola Power PC Processor. Bootstrap software yog khaws cia ntawm Erasable Programmable Read Only Memory (EPROM). Kev ua haujlwm firmware khaws cia rau hauv lub cim xeeb flash thiab tuaj yeem hloov kho dua tshiab ntawm Pem Hauv Ntej Vaj Huam Sib Luag Chaw nres nkoj. Lub Trusted Operating System yog siv rau ntawm TMR Processor thiab CI. Lub sijhawm tiag tiag kernel yog qhov kev kub ceev, kev ua haujlwm siab kernel ua rau kev ua txhaum kev sib faib tshuab. Lub kernel muab cov kev pabcuam yooj yim (xws li kev tswj hwm nco) thiab cuam tshuam tsis pub dawb software ib puag ncig. Lub module watchdog saib xyuas cov haujlwm ua haujlwm thiab cov khoom siv hluav taws xob (PSU) tso zis voltages. Lub module yog muab nrog ib tug dual redundant +24 Vdc fais fab noj los ntawm lub chassis backplane. Lub tshuab hluav taws xob on-board muab kev hloov pauv hloov hluav taws xob, muab cov khoom txias thiab kev tiv thaiv. Lub Trusted CI sib txuas lus nrog TMR Tus Txheej Txheem Trusted ntawm triplicated InterModule Bus. Thaum xaiv tsa los ntawm TMR Processor Trusted, lub module lub tsheb npav interface pov npav cov ntaub ntawv 2 tawm ntawm 3 (2oo3) los ntawm Inter-Module Bus thiab xa rov qab nws cov lus teb los ntawm tag nrho peb Inter-Module Bus raws. Qhov seem ntawm Kev Sib Txuas Lus Interface yog simplex. Tag nrho cov kev sib txuas lus transceivers yog hluav taws xob cais los ntawm ib leeg thiab cov module thiab muaj kev tiv thaiv kev tiv thaiv ntxiv. Cov khoom siv sab hauv module raug cais tawm ntawm dual 24 Vdc pub.

1.3.2. Kev sib txuas lus

Ethernet Media Access Control (MAC) chaw nyob configuration yog tuav los ntawm CI ua ib feem ntawm nws cov ntaub ntawv teeb tsa. Lwm cov ntaub ntawv hais txog qhov chaw nres nkoj thiab kev teeb tsa raws tu qauv tau txais los ntawm TMR Processor, ua ib feem ntawm System.INI cov ntaub ntawv. Cov ntaub ntawv raug xa mus ntawm TMR Processor thiab Kev Sib Txuas Lus Sib Txuas siv ib qho kev sib txuas hu ua Network Variable Manager. Thaum cov ntaub ntawv raug nyeem los ntawm Trusted System, cov ntaub ntawv tau txais los ntawm cov ntawv luam hauv zos khaws cia ntawm Kev Sib Txuas Lus, muab cov lus teb ceev ceev. Cov ntaub ntawv sau yog qhov nyuaj dua. Yog tias cov ntaub ntawv sau yooj yim kho cov ntawv theej hauv zos thiab tom qab ntawd xa mus rau lub processor, lwm qhov kev sib txuas lus hauv lub cev yuav nqa cov ntaub ntawv sib txawv. Qhov no tej zaum yuav ua rau muaj teeb meem rau redundant links. Txhawm rau kov yeej qhov teeb meem no, thaum cov ntaub ntawv sau rau hauv Kev Sib Txuas Lus Sib Txuas, nws yog thawj zaug dhau mus rau TMR Processor thiab kev sau ntawv tau lees paub tam sim ntawd los ntawm Kev Sib Txuas Lus (kom tsis txhob muaj kev sib txuas lus qeeb). Lub processor hloov kho nws tus kheej cov ntaub ntawv thiab tom qab ntawd xa cov ntaub ntawv rov qab mus rau txhua qhov kev sib txuas lus sib txuas kom lawv txhua tus muaj cov ntaub ntawv tib yam. Qhov no tuaj yeem siv ib lossis ob daim ntawv thov scans. Qhov no txhais tau tias tom qab nyeem ntawv yuav tau txais cov ntaub ntawv qub tam sim tom qab sau, kom txog thaum cov ntaub ntawv tshiab tau muab faib. Tag nrho cov kev hloov pauv rau CI .INI tsis tuaj yeem thauj khoom hauv online thiab yuav muaj txiaj ntsig tam sim; Communications Interface disconnects tag nrho cov kev sib txuas lus thiab restarts. Kev sib txuas lus kuj tseem rov pib dua ntawm daim ntawv thov online hloov tshiab thiab raug kaw thaum daim ntawv thov raug tso tseg.
