Garkuwa Grounding: PROFIBUS DP garkuwar kebul dole ne a haɗa shi zuwa ƙasa mai aiki a duka ƙarshen kebul ɗin (ciki har da mai haɗin CI854BK01) don tabbatar da ingantaccen ƙarfin lantarki (EMC), kodayake CI854B/TP854 ya riga ya haɗa garkuwa zuwa ƙasa a ciki ta hanyar masu haɗin sa.
3. Hardware Composition & Architecture
Kit ɗin CI854BK01 ya ƙunshi manyan sassa na jiki guda biyu tare da ayyuka daban-daban:
1. TP854 Sadarwa Baseplate Expansion (CEB):
Wannan ɓangarorin 'passive' ne, wanda aka kafa akan layin dogo na DIN.
Babban aikinsa shi ne samar da mu'amalar haɗin kai ta zahiri, gami da:
* CEX-Bus shigar/masu haɗawa da fitarwa don haɗawa da na'ura mai sarrafa AC 800M.
* Ramin mai haɗa gefen gefen 80-pin don saka ƙirar CI854B.
* Mata biyu masu haɗin DB9 (A & B) don haɗa hanyoyin sadarwar PROFIBUS DP da yawa.
Da zarar an shigar da baseplate kuma an haɗa shi, ya kasance ba a taɓa shi ba yayin sauyawa ko kulawa, yana tabbatar da kwanciyar hankali na filaye.
2. CI854B Module Fadada Sadarwa (CEM):
Wannan shi ne tsarin 'hankali', abin toshewa wanda ya ƙunshi duk ainihin kayan lantarki.
Gine-gine na cikin gida ya dogara ne akan babban MPC880 CPU mai ƙarfi kuma yana haɗa mahimman abubuwan haɗin gwiwa:
* FPGA (Ƙofar Ƙofar Farko): Model Xilinx XC3S1000, yana haɗa na'ura mai laushi na NIOS wanda aka keɓe don sarrafa tari na PROFIBUS DP yarjejeniya don ingantaccen sadarwar lokaci-lokaci.
* Ƙwaƙwalwar ajiya: Ya haɗa da Flash, DDR2 RAM, da Serial Flash PROM don adana shirye-shirye, bayanai, da daidaitawa.
* Sashin Rage Layi: Yana sarrafa sauyawa da saka idanu tsakanin layukan PROFIBUS DP na zahiri guda biyu.
* Canjin DC/DC: Yana canza wutar +24V DC daga CEX-Bus zuwa nau'ikan wutar lantarki da ake buƙata a ciki (misali, +5V, +3.3V).
* Alamar Matsayin LED.
* Logic Interface CEX-Bus & Dual-Port Memory: Yana ba da damar musayar bayanai cikin sauri tare da mai sarrafa AC 800M.
Brief Workflow: Mai sarrafa AC 800M yana aika umarnin sarrafawa da bayanai zuwa CI854B ta hanyar CEX-Bus. CPU da PROFIBUS FPGA a cikin tsarin CI854B sun haɗu don haɗa wannan bayanan cikin telegram bisa ga ka'idar PROFIBUS DP kuma aika su zuwa cibiyar sadarwar filin bas ta hanyar masu haɗin kan TP854 baseplate. A lokaci guda, ana loda bayanan da aka karɓa daga na'urorin bayi akan hanyar sadarwa zuwa mai sarrafawa ta hanyar CEX-Bus. Sashin Redundancy Layin yana ci gaba da lura da ingancin layukan biyu kuma yana yin sauyawa idan ya cancanta.
4. Mabuɗin Shigarwa & Gudanarwa
Shigar da Injini: Da farko, gyara TP854 baseplate akan daidaitaccen layin dogo na DIN. Sannan, daidaita tsarin CI854B tare da ramin 80-pin baseplate kuma saka shi tare da hanyar dogo har sai ya kulle wuri. Tsarin kulle lambar yana tabbatar da ainihin nau'in module ɗin kawai za'a iya shigar dashi.
Haɗin Bus: Yi amfani da igiyoyin igiyoyi masu murɗaɗɗen garkuwa waɗanda suka dace da ƙayyadaddun PROFIBUS DP. Kebul waya A (kore, daidai da RxD/TxD-N) ya kamata a haɗa zuwa PIN 8 na DB9 connector, da kuma waya B (ja, m RxD/TxD-P) zuwa PIN 3. Yana da muhimmanci cewa na USB garkuwa yana da alaka da aiki duniya a duka iyakar na USB. Ko da yake mai haɗin CI854 yana ba da ƙasa na ciki, haɗin ƙasa na waje (misali, ta amfani da matsi na ƙasa) a wurin ƙarewa har yanzu ana buƙatar bin ƙa'idodi da samun ingantaccen rigakafin hayaniya.
Ƙarshen Bus: Dole ne a ƙare cibiyar sadarwa ta PROFIBUS DP tare da masu adawa a kuɗaɗen ƙarshen jiki guda biyu. Ana yin wannan yawanci ta amfani da matosai na DB9 tare da ginannen ciki, masu tsayayyar ƙarewa. A ƙarshen CI854BK01, idan ta kasance a ƙarshen bas ɗin, saita maɓallin ƙarewa a kan mahaɗin da ya dace zuwa 'ON'; idan yana tsakiyar cibiyar sadarwar, saita shi zuwa 'KASHE.'
Wurin Kanfigareshan Mai Ragewa:
Rage Layi: Haɗa kebul na PROFIBUS DP masu zaman kansu guda biyu zuwa tashoshin 'PROFIBUS A' da 'PROFIBUS B' akan TP854, bi da bi.
Babbar Jagora: Yana buƙatar nau'ikan CI854B guda biyu da aka sanya akan su na asali na TP854. PROFIBUS A tashoshin jiragen ruwa ya kamata a haɗa su a layi daya da hanyar sadarwa ta jiki iri ɗaya, da kuma tashoshin PROFIBUS B zuwa cibiyar sadarwa ta jiki iri ɗaya.
Kanfigareshan Software: A cikin ABB's engineering software Control Builder M (CBM), AC 800M hardware hardware dole ne a saita ta ƙara CI854B module da saita PROFIBUS DP master sigogi (misali, tashar tashar, baud rate), jerin bayin da za a leka, da I/O taswira. Fasalolin sakewa kuma suna buƙatar takamaiman saitunan sigar sakewa a cikin CBM. Bayan daidaitawa, zazzage shi zuwa mai sarrafawa.
5. Kulawa & Gyara matsala
CI854BK01 yana ba da cikakkun alamun LED da ƙididdigar tsarin don gano matsala cikin sauri:
Babu LEDs da aka kunna: Bincika idan an haɗa CI854B module a cikin saitin mai sarrafawa kuma an sauke shi; duba fuse CEX-Bus a cikin na'ura mai sarrafa PM8xx; ƙoƙarin bayar da siginar sake saiti (INIT) daga mai sarrafawa.
Laifi (F) LED Ja yana kunne: Zai iya kasancewa yayin farawa/daidaita module (jiran kammalawa), ko akwai kuskuren sanyi. Duba bayanan bincike a cikin CBM. Ƙoƙarin sake saiti; idan laifin ya ci gaba, yi la'akari da maye gurbin tsarin.
