Uhlolojikelele Lomkhiqizo

I-Trusted® TMR 24 Vdc Digital Output Module ixhuma kumadivayisi enkambu angama-40. Ukuhlolwa kokuxilonga okuphindwe kathathu kwenziwa kuyo yonke Imojuli okuhlanganisa ukukalwa kwamanje, kanye ne-voltage engxenyeni ngayinye yesiteshi esiphumayo esivotelwayo. Izivivinyo ziphinde zenzelwe ukuhluleka nokunamathela. Ukubekezelela amaphutha kufinyelelwa ngokwakhiwa kwe-Triple Modular Redundant (TMR) ngaphakathi kweMojuli kushaneli ngayinye ephumayo engama-40. Ukuqapha komugqa okuzenzakalelayo kwedivayisi yasensimini kunikezwa. Lesi sici sivumela Imojula ukuthi ithole kokubili ukwehluleka kokuvula nokufushane kwesekethe kumadivayisi ezintambo zasensimini kanye nokulayisha. Imojuli ihlinzeka ngokulandelana kwezehlakalo okusebhodini (i-SOE) yokubika ngokulungiswa okungu-1 ms. Ukushintsha okukhiphayo kwesimo kubangela ukungena kwe-SOE. Izimo zokuphumayo zinqunywa ngokuzenzakalelayo amandla kagesi kanye nezilinganiso zamanje ebhodini leMojula. Le Module ayigunyaziwe ukuthi ixhumeke ngqo ezindaweni eziyingozi futhi kufanele isetshenziswe ngokuhambisana namadivayisi we-Intrinsic Safety Barrier.

Izici

• 40 amaphuzu okukhiphayo we-Triple Modular Redundant (TMR) Imojula ngayinye. • Ukuxilongwa okuphelele, okuzenzakalelayo kanye nokuzihlola. • Ukuqapha umugqa okuzenzakalelayo ngephuzu ngalinye ukuze kutholwe isekethe evulekile kanye nezintambo zensimu yesifunda esifushane kanye namaphutha okulayisha. • 2500 V impulse imelana ne-opto/galvanic isolation barrier. • Ukuvikelwa kwamanje okuzenzakalelayo (ngeshaneli ngayinye), awadingi amafuse angaphandle. • Ukulandelana kwezehlakalo okusebhodini (i-SOE) ebika ngokulungiswa okungu-1 ms. • Imojula ingashintshwa ngokushisa ku-inthanethi kusetshenziswa ukulungiselelwa kwe-Companion (eduze) okuzinikele noma i-SmartSlot (isikhala esisodwa samamojula amaningi).

Isimo sokuphuma kwephaneli yangaphambili I-Light Emitting Diodes (Ama-LED) endaweni ngayinye ibonisa isimo sokuphumayo kanye namaphutha ezintambo zenkambu. • Ama-LED wesimo Semojuli Yephaneli Yangaphambili abonisa Imojuli yezempilo kanye nemodi yokusebenza (Iyasebenza, Ilindile, Ifundisiwe). • I-TϋV Certified IEC 61508 SIL 3. • Imiphumela inikwa amandla ngamaqembu angawodwa ayisishiyagalombili. Iqembu ngalinye elinjalo yi-Power Group (PG).

I-TMR 24 Vdc Digital Output Module iyilungu lebanga eliThenjiwe lamamojula Okokufaka/Okukhiphayo (I/O). Wonke Amamojula Athenjwayo e-I/O abelana ngokusebenza okufanayo kanye nefomu. Ezingeni elijwayelekile, wonke amamojula e-I/O asebenzelana ne-Inter-Module Bus (IMB) enikeza amandla futhi evumela ukuxhumana ne-TMR Processor. Ukwengeza, wonke Amamojula anesixhumi esibonakalayo senkambu esisetshenziselwa ukuxhuma kumasiginali athile emojuli ensimini. Wonke amamojula ayi-Triple Modular Redundant (TMR).

1.1.I-Field Termination Unit (FTU)

I-Field Termination Unit (FTU) yisigaba se-I/O Module exhumanisa ama-FIU amathathu kusixhumi esibonakalayo senkambu eyodwa. I-FTU ihlinzeka nge-Group Fail Safe Switches kanye nezingxenye zokungenzi lutho ezidingekayo ukuze kulungiswe isignali, ukuvikela i-over-voltage, kanye nokuhlunga kwe-EMI/RFI. Uma ifakwe ku-Trusted Controller noma ku-Expander Chassis, isixhumi senkambu ye-FTU sixhuma ku-Field I/O Cable Assembly enamathiselwe ngemuva kwe-Chassis. Isixhumanisi se-SmartSlot sidluliswa sisuka ku-HIU siye ekuxhumekeni kwenkundla nge-FTU. Lawa masignali aya ngqo kusixhumi sensimu futhi agcine ukuhlukaniswa namasignali e-I/O ku-FTU. Isixhumanisi se-SmartSlot siwukuxhumana okuhlakaniphile phakathi kwamamojula Asebenzayo kanye Namamojuli abekwe eceleni ukuze axhumaniswe ngesikhathi sokushintshwa kweMojula.

1.2.Field Interface Unit (FIU)

I-Field Interface Unit (FIU) yisigaba Semojuli equkethe amasekhethi athile adingekayo ukuze kuxhunyanwe nezinhlobo ezithile zamasignali enkambu ye-I/O. Imojula ngayinye inama-FIU amathathu, eyodwa ngocezu ngalunye. Kumojula ye-TMR 24 Vdc Digital Output, i-FIU iqukethe isigaba esisodwa sesakhiwo sokushintsha okukhiphayo, kanye nesekethe yokuphumayo ye-sigma-delta (ΣΔ) kumphumela ngamunye wenkambu engu-40. Amasekhethi amabili engeziwe e-ΣΔ ahlinzeka ngokuqapha kokuzithandela kwenkambu yangaphandle ye-voltage ye-I/O.

I-FIU ithola amandla angawodwa ku-HIU ngomqondo. I-FIU ihlinzeka ngezimo zamandla ezengeziwe zama-voltage okusebenza adingwa yi-FIU circuitry. Isixhumanisi somkhiqizo esingasodwa esingu-6.25 Mbit/sec sixhuma i-FIU ngayinye kwesinye sezingcezu ze-HIU. I-FIU iphinda ilinganise uhla lwezimpawu "zokugcinwa kwendlu" ebhodini ezisiza ekuqapheni ukusebenza nezimo zokusebenza zeMojuli. Lezi zimpawu zihlanganisa ama-voltage okuphakelwa kukagesi, ukusetshenziswa kwamanje, ama-voltage ereferensi asebhodini kanye nezinga lokushisa lebhodi.

1.3. Iyunithi ye-Host Interface (HIU)

I-HIU iyindawo yokufinyelela ku-Inter-Module Bus (IMB) ye-Module. Iphinde inikeze ukusatshalaliswa kwamandla namandla okucubungula ahlelekayo endawo. I-HIU ukuphela kwengxenye ye-I/O Module ukuxhuma ngokuqondile ku-IMB Backplane. I-HIU ivamile ezinhlotsheni eziningi ze-I/O ezinobuqotho obuphezulu futhi inohlobo oluncike kanye nemisebenzi evamile yomkhiqizo. I-HIU ngayinye iqukethe izingcezu ezizimele ezintathu, ezivame ukubizwa ngokuthi A, B, kanye no-C. Konke ukuxhumana phakathi kwezingcezu ezintathu kufaka ukuhlukaniswa ukuze kusize ukuvimbela noma yikuphi ukusebenzisana kwephutha phakathi kwezingcezu. Ucezu ngalunye lubhekwa njengeFault Containment Region (FCR), njengoba iphutha kucezu olulodwa lingenawo umthelela ekusebenzeni kwezinye izingcezu. I-HIU ihlinzeka ngalezi zinsizakalo ezilandelayo ezivamile kumamojula emndenini: • Ukuxhumana Okubekezelela Amaphutha Esivinini Esiphezulu ngeProsesa ye-TMR ngesixhumi esibonakalayo se-IMB. • I-FCR Interconnect Bus phakathi kwezingcezu zokuvota idatha ye-IMB engenayo nokusabalalisa idatha ye-I/O Module ephumayo ku-IMB. • Isixhumi esibonakalayo sedatha ye-serial esihlukaniswe nge-galvanically kuzingcezu ze-FIU. • Ukwabelana kwamandla okungadingekile we-dual 24 Vdc chassis supply voltage kanye nokulawulwa kwamandla wamandla anengqondo kumjikelezo we-HIU. • Amandla ahlukaniswe ngozibuthe ezingcezu ze-FIU. • Isixhumi esibonakalayo sedatha ye-serial ku-FPU yama-LED wesimo semojuli. • Isixhumanisi se-SmartSlot phakathi kwamamojula Asebenzayo kanye Namamojuli abekwe eceleni ukuze ahlanganiswe ngesikhathi sokushintshwa kweMojuli. • Ukucutshungulwa Kwesiginali Yedijithali ukwenza ukwehlisa idatha yendawo kanye nokuzihlonza. • Izinsiza zememori yasendaweni yokugcina ukusebenza kweMojuli, ukumisa, kanye nedatha yenkambu ye-I/O. • Ukugcinwa kwendlu ebhodini, okuqapha ama-voltage ereferensi, ukusetshenziswa kwamanje kanye nezinga lokushisa lebhodi.
