Zowonetsa Zamalonda

The Trusted® Communications Interface (CI) ndi gawo lanzeru lomwe limapereka njira zingapo zoyankhulirana kwa Woyang'anira Wodalirika, kuchepetsa kulumikizana kwa Triple Modular Redundant (TMR) processor. Module yosinthika ndi ogwiritsa ntchito, CI imatha kuthandizira njira zambiri zolumikizirana. Mpaka ma Communications Interfaces anayi (CIs) atha kuthandizidwa ndi Trusted System.

Mawonekedwe:

• Odalirika Opaleshoni System. • Dual Efaneti ndi madoko anayi siriyo. • Kuthandizira njira zosiyanasiyana zoyankhulirana. • Kulumikizana kotetezeka, kodalirika kudzera pamalumikizidwe apamwamba kwambiri. • Kapolo wa Modbus. • Optional Modbus Master (ndi T812X Trusted processor Interface Adapter). • Kutsatizana Kosasankha Kwa Zochitika (SOE) Pa Modbus. • Front Panel siriyo diagnostic doko, zolakwika ndi udindo zizindikiro.

1.3. Mwachidule

The Trusted CI imapereka System Trust ndi Interface yanzeru Yolumikizirana, yomwe imagwira ntchito ngati njira yolumikizirana pakati pa Purosesa, Ma Trusted Systems ena, Engineering Workstation ndi zida za gulu lachitatu.

1.3.1. Zida zamagetsi

Module ili ndi Motorola Power PC processor. Mapulogalamu a Bootstrap amasungidwa pa Erasable Programmable Read Only Memory (EPROM). Firmware yogwira ntchito imasungidwa mu memory memory ndipo ikhoza kukwezedwa kudzera pa Front Panel Port. The Trusted Operating System imagwiritsidwa ntchito pa TMR processor ndi CI. Kernel ya nthawi yeniyeni ndi liwiro lalikulu, kernel yogwira ntchito kwambiri yomwe imapangidwira machitidwe omwe amagawira zolakwika. Kernel imapereka ntchito zoyambira (monga kasamalidwe ka kukumbukira) komanso kusokoneza mapulogalamu aulere. Module watchdog imayang'anira magwiridwe antchito a purosesa ndi ma voliyumu amagetsi amagetsi (PSU). Gawoli limaperekedwa ndi chakudya chambiri chowonjezera +24 Vdc kuchokera ku chassis backplane. Chigawo chamagetsi pa board chimapereka kutembenuka kwamagetsi, kuwongolera komanso chitetezo. The Trusted CI imalumikizana ndi Trusted TMR Processor kudzera pa InterModule Bus ya katatu. Ikafunsidwa ndi Trusted TMR Processor, mawonekedwe a bus a module amavotera deta 2 mwa 3 (2oo3) kuchokera mu Inter-Module Bus ndikubweza mayankho ake kudzera munjira zonse zitatu za Inter-Module Bus. Yotsalira ya Communications Interface ndi simplex. Ma transceivers onse olumikizirana amakhala olekanitsidwa ndi magetsi kuchokera kwa wina ndi mnzake komanso module ndipo ali ndi njira zina zodzitetezera kwakanthawi. Zothandizira zamkati za module ndizosiyana ndi ma feed a 24 Vdc.

1.3.2. Kulankhulana

Kusintha kwa adilesi ya Ethernet Media Access Control (MAC) kumagwiridwa ndi CI monga gawo lachidziwitso chake. Zambiri zokhuza kukhazikitsidwa kwa doko ndi protocol zimapezedwa kuchokera ku TMR processor, monga gawo la fayilo ya System.INI. Deta imasamutsidwa pakati pa TMR Processor ndi Communications Interfaces pogwiritsa ntchito mawonekedwe omwe amadziwika kuti Network Variable Manager. Deta ikawerengedwa kuchokera ku Trusted System, zomwe zimachokera ku kope lapafupi lomwe limasungidwa pa Communications Interface, zomwe zimayankha mwachangu. Zolemba za data zimakhala zovuta kwambiri. Ngati zolembedwa za data zidangosintha kopi yakumaloko ndikutumizidwa kwa purosesa, ma Communications Interfaces ena mudongosolo amanyamula deta yosiyana. Izi zitha kuyambitsa zovuta pamalumikizidwe osafunikira. Kuti muthane ndi vutoli, data ikalembedwa ku Communications Interface, imaperekedwa koyamba kwa TMR Processor ndipo zolembazo zimavomerezedwa nthawi yomweyo ndi Communications Interface (kupewa kuchedwa kwa kulumikizana). Purosesa imasinthanso nkhokwe yake ndikutumiza deta ku ma Communications Interfaces onse kuti onse akhale ndi data yofanana. Izi zitha kutenga sikani imodzi kapena ziwiri. Izi zikutanthauza kuti zowerengera zotsatila zidzalandira deta yakale nthawi yomweyo pambuyo polemba, mpaka deta yatsopano yagawidwa. Zosintha zonse pazigawo za CI .INI zitha kuikidwa pa intaneti ndipo zidzayamba kugwira ntchito nthawi yomweyo; Communications Interface imadula zolumikizana zonse ndikuyambiranso. Kulumikizana kumayambikanso pakusintha kwa pulogalamu yapaintaneti ndipo kumatsekedwa ntchito ikayimitsidwa.
