The Trusted® Communications Interface (CI) bụ modul nwere ọgụgụ isi nke na-enye ọtụtụ ọrụ nzikọrịta ozi maka onye njikwa ntụkwasị obi, na-ebelata ntinye nzikọrịta nke Triple Modular Redundant (TMR) Processor. Modul nwere ike ịhazi onye ọrụ, CI nwere ike ịkwado ọtụtụ mgbasa ozi nkwukọrịta. Sistemụ tụkwasịrị obi nwere ike ịkwado ihe ruru ihe ntanetị nkwukọrịta anọ (CI).

Atụmatụ:

• Sistemụ arụmọrụ ntụkwasị obi. • Dual Ethernet na ọdụ ụgbọ mmiri anọ. • Nkwado maka ọtụtụ usoro nzikọrịta ozi. • Ozi echekwara echekwabara, ntụkwasị obi site na njikọ nkwukọrịta arụmọrụ dị elu. • Modbus Ohu. • Nhọrọ Modbus Master (ya na T812X Trusted Processor Interface Adapter). Usoro mmemme nke nhọrọ (SOE) karịrị Modbus. • n'ihu Panel serial diagnostic ọdụ ụgbọ mmiri, mmejọ na ọkwa egosi.

1.3. Nchịkọta

CI a tụkwasịrị obi na-enye Sistemụ Ntụkwasị Obi na Interface Communications nwere ọgụgụ isi, na-eme dị ka nfegharị n'etiti Processor, Sistemụ Ntụkwasị Obi ndị ọzọ, Ọrụ Injinia na akụrụngwa ndị ọzọ.

1.3.1. Akụrụngwa

Modul ahụ nwere Motorola Power PC Processor. A na-echekwa sọftụwia bootstrap na Erasable Programmable Read Only Memory (EPROM). A na-echekwa faịlị na-arụ ọrụ na ebe nchekwa flash ma enwere ike ịkwalite ya site na ọdụ ụgbọ mmiri ihu. A na-eji sistemụ arụmọrụ ntụkwasị obi na TMR Processor na CI. Ezigbo kernel bụ oke ọsọ, kernel na-arụ ọrụ dị elu emere maka sistemụ na-anabata mmejọ nkesa. kernel na-enye ọrụ ndị bụ isi (dị ka njikwa ebe nchekwa) yana nnyonye anya gburugburu sọftụwia efu. Onye na-ahụ maka modul na-enyocha ọrụ nhazi yana voltaji mmepụta ike (PSU). A na-enye modul ahụ ya na ntanetị ike +24 Vdc sitere na chassis backplane. Otu ihe na-enye ọkụ na-enye ọkụ na-enye ntụgharị voltaji, nhazi ọkọnọ na nchebe. CI a tụkwasịrị obi na-ekwurịta okwu na TMR Processor tụkwasịrị obi site na ụgbọ ala InterModule atọ. Mgbe TMR Processor tụkwasịrị ntụkwasị obi gbara ajụjụ ọnụ, interface ụgbọ ala modul ahụ na-ahọpụta data 2 n'ime 3 (2oo3) site na Inter-Module Bus wee bufee nzaghachi ya site na ọwa ụgbọ ala Inter-Module atọ niile. Ihe fọdụrụ na Interface Nkwukọrịta bụ simplex. Ndị transceivers nkwukọrịta niile na-ekewapụ onwe ha na igwe eletriki na modul ma nwee usoro nchebe ndị ọzọ na-agafe agafe. Ngwa ime modul dịpụrụ adịpụ na ntanetịime 24 Vdc abụọ.

1.3.2. Nzikọrịta ozi

Ethernet Media Access Control (MAC) nhazi adreesị bụ nke CI na-ejide dịka akụkụ nke ozi nhazi ya. A na-enweta ozi ndị ọzọ gbasara nhazi ọdụ ụgbọ mmiri na protocol site na TMR Processor, dịka akụkụ nke faịlụ System.INI. A na-ebufe data n'etiti TMR Processor na Interfaces Communications site na iji otu interface a na-akpọ Network Variable Manager. Mgbe a na-agụ data site na Sistemụ Ntụkwasị Obi, a na-enweta data ahụ site na nnomi mpaghara echekwara na Interface Communications, na-enye nzaghachi ngwa ngwa. Edemede data dị mgbagwoju anya karị. Ọ bụrụ na ederede data emelitere nnomi mpaghara wee bufee ya na processor, Interfaces Communications ndị ọzọ dị na sistemụ ahụ ga-ebu data dị iche iche. Nke a nwere ike ịkpata nsogbu maka njikọ anaghị arụ ọrụ. Iji merie nsogbu a, mgbe edere data na Nkwukọrịta Nkwukọrịta, a na-ebufe ya na TMR Processor ma dee ya ozugbo site na Nkwukọrịta Nkwukọrịta (iji zere igbu oge nkwukọrịta). Onye nrụpụta ahụ na-emelite nchekwa data nke ya wee ziga data ahụ na ntanetị nkwukọrịta niile ka ha niile nwee otu data. Nke a nwere ike were nyocha otu ma ọ bụ abụọ. Nke a pụtara na ndị na-esote ga-enweta data ochie ozugbo edechara, ruo mgbe ekesara data ọhụrụ. Mgbanwe niile na parampat CI .INI nwere ike ibunye na ntanetị ma ga-enwe mmetụta ozugbo; Interface nzikọrịta ozi na-ewepụ nkwukọrịta niile wee malitegharịa. A na-amalitekwa nzikọrịta ozi na ngwa n'ịntanetị ma mechie ya mgbe akwụsịre ngwa ahụ.
