ʻO ka Trusted® Communications Interface (CI) he module naʻauao e hāʻawi ana i nā lawelawe kamaʻilio no ka Trusted Controller, e hōʻemi ana i ka hoʻouka kamaʻilio ʻana o ka Triple Modular Redundant (TMR) Processor. ʻO kahi module hiki ke hoʻohana ʻia, hiki i ka CI ke kākoʻo i nā media kamaʻilio lehulehu. Hiki ke kākoʻo ʻia a hiki i ʻehā mau Interfaces Communications (CI) e kahi Pūnaehana hilinaʻi.

Nā hiʻohiʻona:

• Pūnaehana lawelawe hilinaʻi. • ʻElua Ethernet a me ʻehā mau awa. • Kākoʻo no ka laulā o nā protocols kamaʻilio. • Paʻa, hilinaʻi kamaʻilio ma o ka hana kiʻekiʻe ka launa pū loulou. • Kauā Modbus. • Koho Modbus Master (me T812X Trusted Processor Interface Adapter). • koho koho o nā hanana (SOE) ma luna o Modbus. • Front Panel serial diagnostic port, hewa a me nā hōʻailona kūlana.

1.3. Nānā nui

Hāʻawi ka Trusted CI i ka Pūnaehana Trusted me kahi Interface Communications naʻauao, e hana ana ma ke ʻano he relay ma waena o ka Processor, nā ʻōnaehana hilinaʻi ʻē aʻe, ka Hana Hana Hana a me nā mea hana ʻekolu.

1.3.1. Lako lako

He Motorola Power PC Processor ka module. Mālama ʻia ka polokalamu Bootstrap ma Erasable Programmable Read Only Memory (EPROM). Mālama ʻia ka firmware hana i ka hoʻomanaʻo flash a hiki ke hoʻonui ʻia ma o ka Front Panel Port. Hoʻohana ʻia ka Pūnaehana Hana Pono ma ka TMR Processor a me CI. ʻO ka kernel manawa maoli he kīkī kiʻekiʻe, hana kiʻekiʻe i hana ʻia no nā ʻōnaehana hoʻomanawanui hewa. Hāʻawi ka kernel i nā lawelawe maʻamau (e like me ka hoʻokele hoʻomanaʻo) a me nā kaiapuni polokalamu manuahi ʻole. Mālama ka ʻīlio kiaʻi module i ka hana ʻana o ka mea hana a me ka mana lako mana (PSU). Hāʻawi ʻia ka module me kahi pālua ʻelua +24 Vdc power feed mai ka chassis backplane. Hāʻawi kahi ʻāpana lako mana ma luna o ka papa i ka hoʻololi ʻana i ka uila, hoʻolako ʻana a me ka pale. Ke kamaʻilio nei ka Trusted CI me ka Trusted TMR Processor ma o ka Bus InterModule triplicated. Ke koho ʻia e ka Trusted TMR Processor, koho ke kikowaena kaʻa o ka module i ka ʻikepili 2 mai ka 3 (2oo3) mai ka Inter-Module Bus a hoʻihoʻi i kāna pane ma o nā alahele ʻekolu Inter-Module Bus. ʻO ke koena o ka Interface Communications he simplex. Hoʻokaʻawale ʻia nā transceiver kamaʻilio a pau mai kekahi i kekahi a me ka module a loaʻa iā ia nā hana pale transient hou. Hoʻokaʻawale ʻia nā lako i loko o ka module mai nā meaʻai pālua 24 Vdc.

1.3.2. Nā kamaʻilio

ʻO ka Ethernet Media Access Control (MAC) ka hoʻonohonoho helu wahi e mālama ʻia e ka CI ma ke ʻano he ʻāpana o kāna ʻike hoʻonohonoho. Loaʻa nā ʻike ʻē aʻe e pili ana i ke awa a me ka hoʻonohonoho protocol mai ka TMR Processor, ma ke ʻano o ka faila System.INI. Hoʻololi ʻia ka ʻikepili ma waena o ka TMR Processor a me nā Communications Interfaces me ka hoʻohana ʻana i kahi kikowaena maʻamau i kapa ʻia ʻo Network Variable Manager. Ke heluhelu ʻia ka ʻikepili mai kahi Pūnaehana Trusted, loaʻa ka ʻikepili mai ke kope kūloko i mālama ʻia ma ka Interface Communications, e hāʻawi ana i ka pane wikiwiki. ʻOi aku ka paʻakikī o ka kākau ʻikepili. Inā hōʻano hou ka palapala ʻikepili i ke kope kūloko a laila hoʻouna ʻia i ka mea hana, e lawe ʻia nā ʻikepili ʻē aʻe i loko o ka ʻōnaehana. Hiki paha kēia i nā pilikia no nā loulou hou. No ka lanakila ʻana i kēia pilikia, ke kākau ʻia ka ʻikepili i kahi Interface Communications, e hāʻawi mua ʻia i ka Processor TMR a e ʻae koke ʻia ka palapala e ka Communications Interface (e pale i ka hoʻopaneʻe kamaʻilio). Hoʻopau ka mea hana i kāna waihona ponoʻī a laila hoʻouna i ka ʻikepili i nā Interfaces Communications āpau i loaʻa iā lākou ka ʻikepili like. Hiki i kēia ke lawe i hoʻokahi a ʻelua paha noiʻi scan. 'O ia ho'i, e loa'a koke mai ka 'ikepili kahiko ma hope o ka heluhelu 'ana, a hiki i ka manawa i puunaue 'ia ai ka 'ikepili hou. Hiki ke hoʻouka ʻia nā hoʻololi a pau i nā ʻāpana CI .INI ma ka pūnaewele a e hoʻokō koke ʻia; hoʻopau ka Interface Communications i nā kamaʻilio āpau a hoʻomaka hou. Hoʻomaka hou ʻia ke kamaʻilio ʻana ma kahi palapala noi pūnaewele a pani ʻia ke pani ʻia ke noi.
