3. Aikace-aikace da Kanfigareshan a cikin S800 I/O System
CI840A shine ainihin bangaren gina tashar S800 I/O. Cikakken tashar I/O ta ƙunshi sassa masu zuwa:
Filin Sadarwar Sadarwar Fieldbus (FCI): Tsarin CI840A (biyu ko ƙari), aiki azaman 'kwakwalwa' na tashar.
Module Termination Unit (MTU): Ƙungiyar tushe don hawa FCI, samar da wutar lantarki, haɗin ModuleBus, da gyarawa. An zaɓa bisa ga buƙatun sakewa na I/O:
TU847: An yi amfani da shi don daidaitawar I/O module ɗin maras nauyi, yana ba da haɗin ModuleBus guda ɗaya.
TU846: An yi amfani da shi don daidaitawar I/O module, samar da haɗin ModuleBus guda biyu, yana tabbatar da hanyoyin sadarwa masu zaman kansu guda biyu don ƙarin nau'ikan nau'ikan nau'ikan I/O module.
I/O Modules: Modules waɗanda ke yin takamaiman aikin shigarwar analog/dijital/fitarwa, waɗanda aka ɗora akan MTU nasu.
ModuleBus Network: ModuleBus bas na ciki mai sauri wanda ke haɗa FCI zuwa duk nau'ikan I/O, an raba su zuwa ModuleBus na Wutar Lantarki (a cikin majalisar, max. tsayin mita 2.5) da ModuleBus na gani (wanda aka haɓaka ta hanyar fiber optic modules kamar TB842, ana amfani da su don gungu masu nisa).
Matsayin Tsarin Gine-gine:
Rukunin Tushe: Ya ƙunshi FCI (CI840A) da samfuran I/O waɗanda aka haɗa kai tsaye da shi ta ModuleBus na Lantarki. Tarin tushe na iya ɗaukar har zuwa 12 waɗanda ba a sake su ba ko kuma nau'ikan nau'ikan I/O guda 6.

Kowane reshe na fiber yana haɗi zuwa TB820V2 ko TB840A ModuleBus Modem, yana samar da gungu na I/O mai nisa. CI840A guda ɗaya na iya sarrafa har zuwa 7 irin waɗannan gungu na I/O masu nisa.
Tashar I/O: FCI ɗaya (ko nau'i-nau'i masu yawa) da duk nau'ikan I/O da ke sarrafa su (ciki har da gungu na tushe da gungu na I/O) sun zama cikakkiyar tashar I/O, tare da matsakaicin matsakaicin iya aiki na 24 I/O kayayyaki.
Tsare-tsare Tsare-tsare na Ragewa:
CI840A tana goyan bayan daidaitawar sakewa don dacewa da matakai daban-daban na buƙatun samuwa:
FCI Redundancy Kawai: Biyu na CI840Kamar yadda aka ɗora su akan TU846/TU847, suna raba ModuleBus iri ɗaya. Idan FCI na farko ya gaza, FCI na jiran aiki zai karɓi sadarwa.
Cikakken Redundancy (FCI & I/O Modules): Biyu na CI840Kamar yadda aka ɗora akan TU846, an haɗa su da na'urori na I/O waɗanda aka saita a cikin redundancy (suna bayyana a nau'i-nau'i, kowane nau'i-nau'i da aka ɗora akan MTUs maras amfani kamar TU842/TU843). Wannan saitin yana ba da cikakkiyar hanyar da ba ta dace ba daga hanyar haɗin sadarwa mai sarrafawa zuwa tashar I / O ta ƙarshe, ta cimma matsayi mafi girma na samuwa.
4. Abubuwan Shigarwa da Kulawa
Zane na CI840A da tsarin S800 I / O sun yi la'akari da dacewa da aiwatar da aikin injiniya da sauƙi na kulawa daga baya.
Shigarwa: Tsarin yana amfani da daidaitaccen hawan dogo na DIN kuma ana iya hawa shi a kwance ko a tsaye (lura da tsananin zafin yanayi don hawa tsaye). Tsarin kulle injina yana tabbatar da amintaccen haɗi. Share masu nuna halin LED (Gudun, Laifi, Matsayin Sadarwa, da sauransu) suna sauƙaƙe bincike cikin sauri. Wutar wuta da haɗin bas suna amfani da tashoshi masu toshewa don sauƙin wayoyi.
Grounding da Garkuwa: Don tabbatar da Daidaituwar Wutar Lantarki (EMC) da amincin sigina, yana da mahimmanci a bi cikakkun jagororin jagorar don saukar da majalisar ministoci da ƙarewar garkuwar kebul na sigina.
Kulawa:
Yin amfani da fasalin Hot Swap, za a iya maye gurbin CI840A ko I/O mara kyau yayin da tsarin ke aiki, yana rage raguwar lokacin da ba a shirya ba.
Ana iya loda wadatattun bayanan bincike zuwa tsarin sarrafawa ta hanyar PROFIBUS, yana taimakawa ma'aikatan kulawa da sauri nuna tushen tushen al'amura, daga matakin ƙirar har zuwa matakin tashar.
Tsarin yana goyan bayan gano ƙirar kan layi da maidowa sanyi, yana ba da damar saukewa ta atomatik ko na hannu bayan maye gurbin module, sauƙaƙe sarrafa kayan gyara.
5. Biyayya da Takaddun shaida
Tsarin CI840A yana bin manyan ka'idojin masana'antu da ka'idojin aminci a kasuwannin duniya kuma ya sami takaddun shaida masu yawa. Wannan yana tabbatar da yarda da aminci ga masu amfani da ke tura samfurin a duk duniya. Waɗannan sun haɗa da alamar CE ta EU (wanda ke rufe EMC da Dokokin Ƙarfin wutar lantarki), EN/UL 61010 jerin ma'auni don amincin lantarki a cikin mahallin masana'antu, takaddun shaida na ATEX da CUlus don wuraren haɗari, da takaddun shaida na ruwa daga manyan ƙungiyoyin rarrabawa (ABS, BV, DNV-GL, LR). Wannan ya sa ya dace da aikace-aikace da yawa a cikin tsire-tsire masu sarrafawa, dandamali na teku, jiragen ruwa, da sauran munanan yanayin masana'antu.
