iimveliso

I-Redundant PROFIBUS Communication Module (FBM222) inikezela nge-interface phakathi kwenkqubo ye-Foxboro Evo kunye ne-PROFIBUS-DP / PA izixhobo zekhoboka, kubandakanywa iimoto zokuqhuba, iimodyuli ze-I / O, kunye nezixhobo ze-I / O zentsimi. I-FBM222, enokusetyenziswa kuqwalaselo olunye okanye olungafunekiyo, ixhasa amakhonkco amabini e-PROFIBUS ngobuninzi bezixhobo zamakhoboka ali-125 kwizibuko ngalinye xa abaphindayo besetyenziswa. I-FBM222 idibanisa izixhobo zekhoboka kwinkqubo yolawulo eguquguqukayo kunye neyomeleleyo yeFoxboro Evo ngokusebenzisa iibhloko zeDistributed Control Interface (DCI). I-Physical PROFIBUS-DP i-wiring ihambelana ne-Electronic Industrial Association (EIA) umgangatho we-RS485. Kukho iindlela ezininzi zokudibanisa i-FBM222s efakwe njengesibini esingafunekiyo kwinethiwekhi ye-PROFIBUS-DP. Xa amacandelo e-PROFIBUS amanethiwekhi omnye njengoko kuboniswe kwi-Figure 1, i-FBM228 / FBM222 i-Redundant Adapter (P0922RK) idibanisa ikhebula elilodwa lokuphelisa kwisibini esingafunekiyo. Esinye isiphelo sekhebula sifakwe kwindibano yokuphelisa (TA), ebonelela ngokudibanisa kumacandelo amabini enethiwekhi (Umfanekiso 1).
