Kakaretso ea Sehlahisoa

Trusted® Communications Interface (CI) ke mojule o bohlale o fanang ka lits'ebeletso tse ngata tsa puisano bakeng sa Molaoli ea Tšeptjoang, o fokotsang phallo ea puisano ea Triple Modular Redundant (TMR) Processor.Mojule o lokisehang ke mosebelisi, CI e ka ts'ehetsa mecha ea puisano e mengata.Ho fihla ho tse 'ne tsa li-Communications Interfaces (CIs) li ka tšehetsoa ke Tsamaiso e Tšeptjoang.

Likaroloana:

• Sistimi ea Ts'ebetso e Tšeptjoang.• Dual Ethernet le likou tse 'nè tsa serial.• Tšehetso bakeng sa mekhoa e mengata ea puisano.• Lipuisano tse sireletsehileng, tse ka tšeptjoang ka lihokelo tsa puisano tse sebetsang hantle.• Mohlanka oa Modbus.• Optional Modbus Master (e nang le T812X Trusted processor Interface Adapter).• Ho Ikhethela Tatelano ea Liketsahalo (SOE) Over Modbus.• Front Panel serial diagnostic boemakepe, phoso le matšoao a boemo.

Mojule ona o na le processor ea Motorola Power PC.Software ea Bootstrap e bolokiloe ho Erasable Programmable Read Only Memory (EPROM).Firmware ea ts'ebetso e bolokiloe mohopolong oa flash mme e kanna ea ntlafatsoa ka Front Panel Port.The Trusted Operating System e sebelisoa ho bobeli TMR Processor le CI.Nako ea 'nete ea kernel ke lebelo le phahameng, kernel ea ts'ebetso e phahameng e etselitsoeng litsamaiso tse ajoang tse mamellang liphoso.Kernel e fana ka lits'ebeletso tsa mantlha (joalo ka taolo ea memori) le tikoloho ea mahala ea software.Setsi sa li-module watchdog se lekola ts'ebetso ea processor le li-voltage tsa phano ea motlakase (PSU).Mojule o fanoa ka phepelo ea matla a mabeli +24 Vdc e tsoang mokokotlong oa chassis.Setsi sa phepelo ea motlakase se ka har'a board se fana ka phetolo ea motlakase, boemo ba phepelo le ts'ireletso.The Trusted CI e buisana le Trusted TMR Processor ka InterModule Bus e likarolo li tharo.Ha ho etsoa lipatlisiso ke Trusted TMR Processor, sebopeho sa libese sa module se voutela data 2 ho tse 3 (2oo3) ho tsoa ho Inter-Module Bus mme e fetisetsa karabo ea eona ka likanale tse tharo tsa Inter-Module Bus.Karolo e setseng ea Sehokelo sa Lipuisano ke simplex.Li-transceivers tsohle tsa puisano li arohane ka motlakase ho tloha ho tse ling le module mme li na le mehato e meng ea ts'ireletso ea nakoana.Lisebelisoa tsa kahare tsa mojule li arotsoe ho li-feed tsa 24 Vdc tse peli.

1.3.2.Lipuisano

Tokiso ea aterese ea Ethernet Media Access Control (MAC) e ts'oaroa ke CI e le karolo ea tlhaiso-leseling ea eona.Lintlha tse ling mabapi le phetisetso ea boema-kepe le liprothokholo li fumaneha ho TMR Processor, e le karolo ea faele ea System.INI.Lintlha li fetisetsoa lipakeng tsa TMR Processor le Litšebelisano tsa Lipuisano ho sebelisoa sebopeho se tloaelehileng se bitsoang Network Variable Manager.Ha data e baloa ho tsoa ho Sistimi e Tšeptjoang, lintlha li fumanoa ho tsoa kopi ea lehae e bolokiloeng ho Sehokelo sa Khokahano, e fanang ka karabelo e potlakileng.Lintlha tse ngolang li rarahane ho feta.Haeba mongolo oa data o nchafalitse kopi ea lehae ebe o fetisetsoa ho processor, li-interfaces tse ling tsa likhokahano tsamaisong li ne li tla ba le data e fapaneng.Sena se ka baka mathata ho li-link tse sa hlokahaleng.Ho hlōla bothata bona, ha data e ngolloa ho Communications Interface, e qala ho fetisetsoa ho TMR Processor 'me mongolo o amoheloa hang-hang ke Communications Interface (ho qoba tieho ea puisano).Motlakase o nchafatsa polokelong ea ona ebe o khutlisetsa data ho Litšebelisano tsohle tsa Khokahano e le hore kaofela ba be le data e tšoanang.Sena se ka nka sesebelisoa se le seng kapa tse peli.Sena se bolela hore litlaleho tse latelang li tla fumana data ea khale hang ka mor'a ho ngola, ho fihlela data e ncha e abuoe.Liphetoho tsohle ho li-parameter tsa CI .INI li ka kenngoa inthaneteng 'me li tla sebetsa hang-hang;Sehokelo sa Lipuisano se hakolla likhokahano tsohle ebe se qala bocha.Lipuisano li boetse li qalisoa bocha ho ntlafatso ea inthaneteng 'me lia koaloa ha ts'ebeliso e emisoa.
