Multi-Vendor Interface (MVI): Yana goyan bayan daidaitattun ka'idojin masana'antu irin su RCOM, MODBUS, Siemens 3964 (R), da dai sauransu (ta hanyar C1532Vxx ko C1534Vxx submodules), kazalika da aikace-aikacen aikace-aikacen kyauta don ƙayyadaddun ka'idojin mai amfani (ta C1538 submodules).
Raba Load ta hanyar CPU na gida: Wannan shine babban fa'idar SC520. Don wasu ayyuka masu ɗaukar nauyi ko mahimmancin lokaci mai mahimmanci (misali, sadarwar cibiyar sadarwa na MasterBus 300/300E), zaɓin akwai zaɓi don aiwatar da sarrafa tarin tsarin sadarwa akan CPU na gida na SC520 maimakon babban mai sarrafa CPU (PM511). Wannan yanayin 'wanda aka aiwatar a cikin bawa CPU' yana iya rage nauyi sosai akan babban CPU (takardun yana nuna ƙananan babban nauyin CPU don aikawa da karɓa lokacin amfani da SC520 idan aka kwatanta da mai ɗaukar SC510 ba tare da CPU na gida ba). Wannan yana 'yantar da manyan albarkatun CPU don aiwatar da dabaru masu mahimmanci, algorithms, da aiwatar da I/O, don haka inganta aikin tsarin gabaɗaya.
Taimakon Sadarwa Mai Sauƙi: Ana iya saita SC520 da ƙananan na'urorin sa a matsayin wani ɓangare na hanyoyin haɗin yanar gizo, kamar gina sabbin hanyoyin sadarwa na MasterBus 300 ko cibiyoyin sadarwa Advant Fieldbus 100, haɓaka amincin tsarin sadarwa.
3. Haɗin Tsari da Ayyukan Bincike:
Haɗin Tsarin Tsari mara Sumul: A matsayin wani ɓangare na daidaitaccen tsarin gine-ginen Advant OCS, SC520 ya dace da software na tsari (misali, samfuran shirye-shirye kamar QC07-BAS41). Ana gane ƙayyadaddun ƙayyadaddun tsarin sa da kuma daidaita su ta atomatik a cikin tsarin. Ana iya tsara ayyukan sadarwa cikin sauƙi da samun dama ta hanyar abubuwan PC masu dacewa a cikin AMPL (ABB Master Programming Language), kamar COM-STAT , DSP-R , DSP-S , MFB-IN , MFB-OUT , da sauransu.

III. Ƙa'idar Aiki da Gine-gine
Ƙa'idar aiki na SC520 ta dogara ne akan ingantaccen gine-ginen sarrafawa da aka rarraba da falsafar ƙirar ƙira. Hanyoyin aiki da tsarin haɗin gwiwar ciki sune kamar haka:
1. Hardware Architecture da Bus Interaction:
Shi kansa SC520 wani hadadden allon da'ira ne, wanda asalinsa shine hadedde microprocessor na gida (CPU). An haɗa wannan na'ura mai mahimmanci zuwa babban samfurin PM511 ta hanyar bas mai sauri mai sauri (dangane da ma'aunin Futurebus + a cikin Advant Controller 450). Wannan bas shine ' babbar hanya' don bayanai da musayar umarni.
Musanya Bayanai: Babban CPU (PM511) yana amfani da wannan bas don rubuta fakitin bayanai, umarni masu sarrafawa, ko sigogin daidaitawa waɗanda aka keɓance don cibiyoyin sadarwa na waje zuwa cikin yankin ƙwaƙwalwar ajiyar da aka raba na SC520 da ƙananan kayan aikin sa. Sabanin haka, CPU na gida akan SC520 yana rubuta bayanai, bayanin matsayi, ko rahotannin taron da aka karɓa daga cibiyoyin sadarwa na waje zuwa wuraren ƙwaƙwalwar ajiya waɗanda babban CPU ke samun dama ta hanyar bas iri ɗaya.
Katsewa da Haɗin kai: Dukan ɓangarorin biyu za su iya sanar da juna sabbin ayyuka ko bayanan da ke jiran aiki ta hanyoyin katsewa, ba da damar ingantaccen aikin haɗin gwiwa.
2. Matsayin CPU na gida da 'Load Sharing' Ka'ida:
CPU na gida na SC520 yana aiki azaman 'kofar sadarwa' ko 'teway na hankali.' Yanayin aiki da farko ya dogara da nau'in submodule na sadarwa da aka shigar da tsarin tsarin:
Yanayin Gudanar da Yarjejeniya: Don wasu ƙananan tsarin sadarwa (misali, CS513 MasterBus 300 da aka saita don 'wanda aka aiwatar a cikin bawa CPU' yanayin), ana sarrafa sarrafa ƙasa zuwa tsakiyar yadudduka na tarin ka'idar sadarwa (misali, firam encapsulation/decapsulation, sarrafa hanyar haɗin gwiwa, gano kuskure, ikon samun damar watsa labarai20) ana sarrafa dukkan CPU na gida. CPU na gida da kansa yana sarrafa hanyar sadarwa ta hanyar sadarwa, yana aiwatar da danyen bayanai akan hanyar sadarwar, kuma yana wuce ingantaccen bayanan-Layer na aikace-aikace (ko abubuwan da suka faru) zuwa babban CPU ta hanyar bas ɗin baya. Akasin haka, yana tattara bayanan aikace-aikacen da aka karɓa daga babban CPU zuwa cikin firam ɗin da suka dace da ka'idar cibiyar sadarwa kuma tana watsa su. Amfanin wannan yanayin shine:
Rage Babban Load ɗin CPU: Yana saukar da ayyukan sarrafa ka'idojin sadarwa na lokaci-lokaci da na lokaci-lokaci daga babban CPU, yana ba shi damar mai da hankali kan zagayowar ɗawainiya tare da ƙayyadaddun ƙayyadaddun buƙatun.
Ingantattun Ayyukan Aiki na Gaskiya: CPU na gida na iya ba da amsa ga abubuwan da ke faruwa a cibiyar sadarwa da sauri, rage jinkirin sadarwar da ke haifar da cunkoson babban aikin CPU.
Ingantattun Ayyukan Tsari: Yana ba da damar tsarin don sarrafa zirga-zirgar sadarwar cibiyar sadarwa mai yawa ba tare da tasirin aikin sarrafawa ba.
Gudanar da Interface/Mai-wucewa-Ta Yanayin: Don wasu ƙananan ƙwayoyin cuta (misali, C1531 RS-232 dubawa), CPU na gida na iya ɗaukar farawar fara dubawa, saitin siga, buffer bayanai, da sarrafa kwarara. Ana iya yin nazarin abubuwan da ke cikin bayanai ta software (misali, direbobin EXCOM) masu gudana akan babban CPU. Duk da haka, kasancewar CPU na gida yana sauƙaƙa nauyin direba akan babban CPU.
3. Haɗin kai tare da Submodules:
SC520 yana ba da daidaitaccen tsarin lantarki da ma'ana don kowane ramin ƙaramin abu. CPU na gida yana sadarwa tare da kowane ƙaramin abu ta hanyar bas na ciki ko keɓaɓɓen keɓancewa don farawa, sarrafawa, da saka idanu na matsayi.
Ƙaddamarwa da Haɓakawa: Yayin farawa tsarin, babban CPU yana ba da umarnin CPU na gida na SC520 ta hanyar bas na baya don kunnawa, yin gwaje-gwajen kai, da kuma saita sigogi don kowane ƙaramin abu.
Rarraba Aiki da Gudanar da Bayanai: Gidan CPU na gida yana bibiyar bayanai zuwa madaidaicin ƙaramin abu dangane da wurin sadarwa. Misali, bayanan da aka ƙaddara don hanyar sadarwa ta MasterBus 300 ana miƙa su ga CS513 submodule, yayin da aka aika da bayanai don firinta na serial zuwa ƙaramin tsarin C1531.
Warewa Laifi: Idan ƙaramin na'ura ya gaza, CPU na gida na SC520 na iya ganowa da ware shi, yana hana laifin yin tasiri ga wasu ƙananan ƙwayoyin cuta ko bas ɗin baya, kuma su kai rahoto ga babban CPU ta hanyoyin ganowa.
4. Role in System Redundancy:
A cikin tsarin da aka daidaita tare da raka'a 450 Advant Controller (dual PM511) ko cibiyoyin sadarwa maras amfani, SC520 na iya tallafawa sakewa don hanyoyin sadarwa masu mahimmanci.
Hanyoyin Sadarwar Sadarwa: Za a iya shigar da ƙananan tsarin sadarwa guda biyu (misali, C1522A guda biyu don Advant Fieldbus 100), kowannensu yana da alaƙa da cibiyoyin sadarwa na jiki masu zaman kansu. CPU na gida na SC520 na iya sarrafa matsayi na musaya biyu, ta atomatik ko canzawa da hannu zuwa hanyar haɗin yanar gizo idan na farko ya gaza.
Haɗin kai tare da CPUs masu yawa: A cikin saitunan sarrafawa, manyan CPUs PM511 guda biyu yawanci suna raba mahimman albarkatun sadarwa. Dole ne SC520 da ƙananan na'urorinsa su kasance masu isa da sarrafa su ta manyan CPUs guda biyu, tabbatar da cewa duk hanyoyin sadarwar waje za a iya canja su ba tare da wata matsala ba ko kuma a sake kafa su cikin sauri yayin jujjuyawar firamare/ajiyayyen.
5. Haɗin software da Firmware:
Ayyukan SC520 da CPU na gida sun dogara da firmware da tallafin software na tsarin. Wannan software yawanci ana haɗa shi cikin tsarin tsarin tsarin tushen Advant Controller 450 (QC07-BAS41). A lokacin fara tsarin, yayin da ake loda nata software na tsarin, babban CPU kuma yana loda firmware da direbobi a cikin CPU na gida na SC520. A matakin shirye-shiryen aikace-aikacen, injiniyoyi ba sa tsara SC520 kai tsaye. Maimakon haka, suna amfani da ƙarfin sadarwa mai ƙarfi da SC520 ke bayarwa a kaikaice ta hanyar daidaita bayanan tsarin mai sarrafawa da tsara abubuwan da suka dace da PC na sadarwa.
