Mawonekedwe Odalirika a TMR Processor Product

The Trusted® Processor ndiye gawo lalikulu lokonzekera mu Trusted System. Ndi gawo lamphamvu, losinthika ndi ogwiritsa ntchito lomwe limapereka kuwongolera kwamakina onse ndikuwunikira ndikuwongolera zomwe zalandilidwa ndi zotuluka kuchokera kumitundu yosiyanasiyana ya analogi ndi ma module a Digital Input / Output (I/O) kudutsa Mabasi Odalirika a TMR Inter-Module Communications. Mitundu yosiyanasiyana ya mapulogalamu a Trusted TMR Processor amasiyana mu umphumphu ndipo amaphatikizapo kulamulira moto ndi gasi, kuzimitsa mwadzidzidzi, kuyang'anira ndi kulamulira, ndi kulamulira kwa turbine.

Mawonekedwe:

• Katatu Modular Redundant (TMR), kulekerera zolakwika (3-2-0). • Zomangamanga za Hardware Implemented Fault Tolerant (HIFT). • Ma hardware odzipatulira ndi machitidwe oyesera mapulogalamu omwe amapereka chidziwitso chachangu kwambiri komanso nthawi yoyankha. • Kusamalira zolakwika zokha popanda vuto lowopsa. • Wolemba mbiri ya zolakwika wolembedwa ndi nthawi. • Kusintha kotentha (palibe chifukwa choyikanso mapulogalamu). • Mndandanda wathunthu wa zinenero za IEC 61131-3. • Zizindikiro zakutsogolo zomwe zikuwonetsa thanzi la gawo ndi momwe alili. • Front panel RS232 serial diagnostics port for system monitoring, configuration and programming. • IRIG-B002 ndi zizindikiro za nthawi 122 (zikupezeka pa T8110B kokha). • Yogwira ndi Standby purosesa cholakwika ndi kulephera kulankhula. • Mawaya awiri a RS422 / 485 osinthika 2 kapena 4 (akupezeka pa T8110B kokha). • Kulumikiza waya kumodzi kwa RS485 2 (kukupezeka pa T8110B kokha). • TϋV Wotsimikizika wa IEC 61508 SIL 3.

1.1. Mwachidule

The Trusted TMR Processor ndi kamangidwe kolekerera zolakwika kutengera kamangidwe ka Triple Modular Redundant (TMR) komwe kumagwira ntchito potseka masitepe. Chithunzi 1 chikuwonetsa, m'mawu osavuta, mawonekedwe oyambira a Trusted TMR processor module. Mutuwu uli ndi zigawo zitatu za processor zolakwitsa (FCR), iliyonse ili ndi Motorola Power PC series processor ndi kukumbukira kwake (EPROM, DRAM, Flash ROM, ndi NVRAM), kukumbukira mapu a I / O, ovota ndi mabwalo omveka a glue. Prosesa iliyonse ya FCR yavotera awiri mwa atatu (2oo3) kuti awerenge mwayi wofikira kumakina ena awiri a processor a FCR kuti athetse magwiridwe antchito osiyanasiyana. Ma module atatu a processors amasunga ndikugwiritsa ntchito pulogalamuyo, sankhani ndikusintha ma module a I/O ndikuwona zolakwika zamakina. Purosesa iliyonse imagwiritsa ntchito pulogalamu yodziyimira payokha, koma polumikizana ndi ena awiriwo. Ngati mmodzi wa Ma processor asiyanitsidwa, njira zowonjezera zimalola purosesa yolephera kuti ilumikizanenso ndi ena awiriwo. Purosesa iliyonse ili ndi mawonekedwe omwe amakhala ndi ovota, malingaliro ozindikira kusiyana, kukumbukira, ndi mawonekedwe amabasi oyendetsa kupita ku Inter-Module Bus. Zotulutsa za Purosesa iliyonse zimalumikizidwa ndi cholumikizira cha module kunjira ina ya Triplicated Inter-Module Bus.

3. Kugwiritsa ntchito

3.1. Kukonzekera kwa Module Purosesa yodalirika ya TMR imasowa kasinthidwe ka hardware. Dongosolo Lililonse Lodalirika limafunikira fayilo yosinthira ya System.INI. Tsatanetsatane wa momwe mungapangire izi zaperekedwa mu PD-T8082 (Trusted Toolset Suite). Kukonzekera kuli ndi Purosesa yoperekedwa kumanzere kwa processor chassis mwachisawawa. System Configurator imalola kusankha zosankha pamadoko, IRIG ndi ntchito zamakina. Kugwiritsa ntchito System Configurator kumafotokozedwa mu PD-T8082. Zosankha zafotokozedwa pansipa.

3.1.1. Gawo Lowonjezera Ngati Auto Protect Network Variables yasankhidwa, izi zimakonza Trusted System kuti igwiritse ntchito mapu ochepetsedwa a Modbus Protocol. Onani kufotokoza kwazinthu PD-8151B (Trusted Communication Interface Module) kuti mumve zambiri. Inter Group Delay ikufanana ndi kusintha kwa Modbus. Iyi ndi nthawi yochepa pakati pa mauthenga otsatizanatsatizana a Modbus omwe amatumizidwa ku iliyonse ya Communications Interface Modules. Mtengo wokhazikika (monga momwe zasonyezedwera) ndi 50 ms zomwe zimapereka kusagwirizana pakati pa latency ndi ntchito. Kusintha kumapangidwa mu 32 integer ms increments, mwachitsanzo, mtengo wa 33 udzakhala wofanana ndi 64 ms monga 64. Izi zikhoza kuonjezedwa kapena kuchepetsedwa monga momwe zimafunira, komabe popeza uthenga umodzi wokha umatumizidwa pa sikani ya pulogalamu, ndipo jambulani pulogalamu nthawi zambiri ikhoza kukhala kuposa 50 ms, palibe phindu pakusintha kusinthaku.

3.1.2. Gawo la Chitetezo Chowonetsera pamwambapa chimagwiritsidwanso ntchito kukonza mawu achinsinsi omwe amalola wosuta kuti afunse mafunso pa Trusted System pogwiritsa ntchito Windows-based HyperTerminal Center kapena pulogalamu yofananira. Mawu achinsinsi amakonzedwa posankha batani la New Password ndikulowetsa mawu achinsinsi kawiri mubokosi la zokambirana lomwe likuwonetsedwa.

3.1.3. Gawo la ICS2000 Gawoli likugwira ntchito ku Trusted Systems yolumikizidwa kudzera pa Trusted to ICS2000 Interface Adapter kupita ku ICS2000 system. Izi zimalola magwero a deta kuti asankhe matebulo otsanzira atatu. Chonde tumizani kwa Wodalirika sapulani wanu kuti mudziwe zambiri.
