Tso siab tau TMR Processor Product Overview

Trusted® Processor yog cov khoom tseem ceeb hauv kev ntseeg siab.Nws yog lub zog muaj zog, tus neeg siv-configurable module muab tag nrho cov kev tswj hwm thiab saib xyuas cov chaw thiab cov txheej txheem tawm tswv yim thiab cov ntaub ntawv tau txais los ntawm ntau yam analogue thiab digital Input / Output (I / O) modules thoob plaws TMR Inter-Module Communications Bus.Qhov ntau ntawm cov ntawv thov rau TMR Trusted Processor sib txawv hauv qib kev ntseeg siab thiab suav nrog kev tswj hluav taws thiab roj, kev kaw thaum muaj xwm txheej ceev, kev saib xyuas thiab tswj, thiab kev tswj xyuas turbine.

Nta:

• Triple Modular Redundant (TMR), ua haujlwm tsis raug cai (3-2-0).• Hardware Implemented Fault Tolerant (HIFT) architecture.• Dedicated hardware and software test regimes uas muab ceev heev ua txhaum thiab lub sij hawm teb.• Tsis siv neeg ua txhaum cai yam tsis muaj teeb meem.• Time-stamped txhaum historian.• Kub hloov (tsis tas yuav rov thauj cov kev pab cuam).• Cov lus tag nrho ntawm IEC 61131-3 programming languages.• Pem hauv ntej vaj huam sib luag ntsuas uas qhia module noj qab haus huv thiab raws li txoj cai.• Pem hauv ntej vaj huam sib luag RS232 serial diagnostics chaw nres nkoj rau system xyuas, configuration thiab programming.• IRIG-B002 thiab 122 lub sij hawm synchronization signals (muaj nyob rau ntawm T8110B nkaus xwb).• Active thiab Standby processor txhaum thiab tsis ua hauj lwm tiv tauj.• Ob lub RS422 / 485 configurable 2 lossis 4 xaim txuas (muaj nyob ntawm T8110B nkaus xwb).• Ib qho RS485 2 hlau txuas (muaj nyob ntawm T8110B nkaus xwb).• TϋV Certified IEC 61508 SIL 3.

1.1.Txheej txheem cej luam

Tus Txheej Txheem TMR Trusted yog qhov ua txhaum kev tsim qauv raws li Triple Modular Redundant (TMR) architecture ua haujlwm hauv kev ntsuas xauv-kauj ruam.Daim duab 1 qhia tau hais tias, hauv cov ntsiab lus yooj yim, cov qauv yooj yim ntawm TMR Processor Module.Lub module muaj peb qhov chaw ua haujlwm txhaum cai (FCR), txhua qhov muaj Motorola Power PC series Processor thiab nws cov cim xeeb cuam tshuam (EPROM, DRAM, Flash ROM, thiab NVRAM), nco mapped I / O, cov neeg pov npav thiab cov nplaum logic circuits.Txhua Tus Txheej Txheem FCR tau pov npav ob-tawm-ntawm-peb (2oo3) nyeem nkag mus rau lwm tus Processor FCR lub cim xeeb kom tshem tawm cov haujlwm sib txawv.Lub module peb tus Txheej Txheem khaws cia thiab ua tiav daim ntawv thov kev pab cuam, luam theej duab thiab hloov kho I / O modules thiab kuaj xyuas qhov ua tsis raug.Txhua Tus Txheej Txheem ua tiav daim ntawv thov kev pab cuam ntawm nws tus kheej, tab sis nyob rau hauv xauv-kauj ruam synchronization nrog rau lwm ob.Yog tias ib qho ntawm Cov Txheej Txheem sib txawv, cov txheej txheem ntxiv tso cai rau tus txheej txheem ua tsis tiav los rov ua kom sib txuas nrog lwm ob.Txhua Tus Txheej Txheem muaj qhov sib cuam tshuam uas muaj cov neeg pov npav tawm suab, qhov sib txawv ntawm qhov ntsuas qhov ntsuas, nco, thiab qhov tso zis tsav tsheb sib txuas rau Inter-Module Bus.Cov zis ntawm txhua tus processor yog txuas nrog lub module txuas mus rau ib qho chaw sib txawv ntawm lub tsheb npav triplicated Inter-Module.

3. Daim ntawv thov

3.1.Module Configuration Tus Trusted TMR Processor yuav tsum tsis muaj kho vajtse configuration.Txhua qhov Trusted System yuav tsum muaj System.INI configuration file.Cov ntsiab lus ntawm yuav tsim qhov no li cas yog muab rau hauv PD-T8082 (Trusted Toolset Suite).Cov kev teeb tsa muaj tus Txheej Txheem tau muab rau sab laug ntawm tus processor chassis los ntawm lub neej ntawd.Qhov System Configurator tso cai rau kev xaiv cov kev xaiv ntawm cov chaw nres nkoj, IRIG thiab cov haujlwm ua haujlwm.Kev siv System Configurator tau piav qhia hauv PD-T8082.Cov kev xaiv tau piav qhia hauv qab no.

3.1.1.Updater Section Yog xaiv Auto Protect Network Variables, qhov no configures Trusted System siv ib tug txo Modbus raws tu qauv daim ntawv qhia.Saib cov khoom piav qhia PD-8151B (Trusted Communication Interface Module) kom paub meej ntxiv.Inter Group ncua sijhawm sib npaug rau Modbus hloov tshiab lub voj voog.Qhov no yog lub sijhawm tsawg kawg ntawm cov lus hloov tshiab Modbus txuas ntxiv mus rau txhua qhov kev sib txuas lus Interface Modules.Tus nqi pib (raws li qhia) yog 50 ms uas muab kev cuam tshuam ntawm latency thiab kev ua haujlwm.Kev hloov kho yog ua nyob rau hauv 32 integer ms increments, piv txwv li tus nqi ntawm 33 yuav sib npaug 64 ms raws li yuav 64.Qhov no tej zaum yuav nce los yog txo raws li qhov yuav tsum tau, tab sis txij li thaum tsuas yog ib qho kev hloov tshiab yog xa mus rau ib daim ntawv thov scan, thiab daim ntawv thov scan feem ntau yuav yog. ntau tshaj 50 ms, tsis muaj txiaj ntsig zoo hauv kev kho qhov hloov pauv no.

3.1.2.Kev Ruaj Ntseg Cov zaub saum toj no kuj tseem siv los teeb tsa tus password uas tso cai rau tus neeg siv los nug lub Trusted System siv lub Windows-based HyperTerminal facility los yog cov kev pab cuam zoo sib xws.Tus password raug teeb tsa los ntawm kev xaiv tus password tshiab khawm thiab nkag mus rau tus password tshiab ob zaug hauv lub thawv sib tham.

3.1.3.ICS2000 Seem Tshooj lus no tsuas yog siv rau Trusted Systems txuas los ntawm Trusted to ICS2000 Interface Adapter rau ICS2000 system.Qhov no tso cai rau cov ntaub ntawv qhov chaw rau peb lub rooj sib tw yuav raug xaiv.Thov xa mus rau koj tus neeg muag khoom ntseeg siab yog xav paub ntxiv.
