Product Overview

The Trusted® Communications Interface (CI) imodule ine hungwaru inopa huwandu hwemasevhisi ekutaurirana kune Akavimbika Controller, ichideredza kurodha kwekutaurirana kweTriple Modular Redundant (TMR) processor. Mushandisi-inogadziriswa module, iyo CI inogona kutsigira akawanda ekukurukurirana midhiya. Anosvika mana Communications Interfaces (CIs) anogona kutsigirwa neTrusted System.

Features:

• Yakavimbika Operating System. • Dual Ethernet uye ina serial ports. • Rutsigiro rwezvakasiyana-siyana zvezvibvumirano zvekutaurirana. • Kukurukurirana kwakachengeteka, kwakavimbika kuburikidza nepamusoro pekuita zvekutaurirana zvinongedzo. • Modbus Muranda. • Optional Modbus Master (ine T812X Trusted processor Interface Adapter). • Optional Sequence Of Events (SOE) Pamusoro peModbus. • Front Panel serial diagnostic port, kukanganisa uye chimiro zviratidzo.

1.3. Overview

Iyo Yakavimbika CI inopa Yakavimbika Sisitimu ine hungwaru Yekukurukurirana Interface, ichiita senge relay pakati peProsesa, mamwe maSystem Akavimbika, Injiniya Workstation uye yechitatu-bato michina.

1.3.1. Hardware

Iyo module ine Motorola Power PC processor. Bootstrap software inochengetwa paErasable Programmable Read Only Memory (EPROM). Operational firmware inochengetwa muflash memory uye inogona kukwidziridzwa kuburikidza neFront Panel Port. Iyo Yakavimbika Operating System inoshandiswa pane ese ari maviri TMR processor uye CI. Iyo chaiyo nguva kernel ndeyekumhanya kwakanyanya, yakakwirira mashandiro kernel akagadzirirwa kukanganisa anoshivirira masisitimu akagoverwa. Iyo kernel inopa masevhisi ekutanga (senge memory manejimendi) uye kukanganisa yemahara software nharaunda. A module watchdog inotarisisa processor mashandiro uye iyo magetsi emagetsi unit (PSU) inobuda voltages. Iyo module inopihwa neaviri redundant +24 Vdc simba rekudya kubva kune chassis backplane. Iyo pane-bhodhi magetsi emagetsi unit inopa kutendeuka kwemagetsi, kugovera mamiriro uye kudzivirira. Iyo Yakavimbika CI inotaurirana neTrusted TMR Processor kuburikidza nekatatu InterModule Bhazi. Kana yakabvunzurudzwa neTrusted TMR processor, iyo module yebhazi interface inovhota iyo data 2 kubva pa3 (2oo3) kubva kuInter-Module Bhazi uye inodzosera mhinduro yayo kuburikidza ese matatu Inter-Module Bhazi chiteshi. Iyo yasara yeCommunication Interface iri simplex. Ese matransceivers ekutaurirana akaparadzaniswa nemagetsi kubva kune mumwe nemumwe uye module uye ane mamwe ekuwedzera ekudzivirira ekudzivirira matanho. Iyo module yemukati zvekushandisa zvakaparadzaniswa kubva kune mbiri mbiri 24 Vdc feed.

1.3.2. Communications

Ethernet Media Access Control (MAC) kero kumisikidzwa inobatwa neCI sechikamu cheruzivo rwayo rwekugadzirisa. Rumwe ruzivo nezve port uye protocol kumisikidzwa inowanikwa kubva kuTMR processor, sechikamu cheSystem.INI faira. Data inotamiswa pakati peTMR Processor neCommunication Interfaces vachishandisa yakajairwa interface inonzi Network Variable Manager. Kana data ikaverengwa kubva kuTrusted System, data racho rinotorwa kubva kukopi yeko inochengetwa paCommunication Interface, ichipa mhinduro inokurumidza. Zvinyorwa zvinyorwa zvakanyanya kuoma. Kana data rakanyorwa richingovandudza kopi yenzvimbo uye rozoendeswa kune processor, mamwe maCommunication Interfaces ari musystem anotakura data rakasiyana. Izvi zvinogona kukonzera matambudziko kune redundant links. Kuti ukunde dambudziko iri, kana data yakanyorerwa kuCommunication Interface, inotanga kupfuudzwa kuTMR Processor uye kunyora kunobvumwa nekukasira neCommunication Interface (kudzivisa kunonoka kutaurirana). Iyo processor inogadziridza dhatabhesi yayo uye yozotumira iyo data kumashure kune ese eCommunication Interfaces kuti vese vave nedata rakafanana. Izvi zvinogona kutora imwe kana maviri application scans. Izvi zvinoreva kuti kuverenga kunotevera kuchagamuchira data yekare pakarepo mushure mekunyora, kusvikira data itsva yagoverwa. Zvose zvinoshanduka kuCI .INI parameters inogona kutakurwa paIndaneti uye inotora simba pakarepo; iyo Communications Interface inobvisa kutaurirana kwese uye inotangazve. Nhaurirano inotangwa zvakare pane application online update uye inovharwa kana application yamira.
