mankhwala

NKHANI Mbali zazikulu za FBM233 ndi izi:  Redundant 10 Mbps kapena 100 Mbps Ethernet network transmission rate to/ from field devices  Imalumikizana ndi zida 64 za m'munda  I/O software driver is downloaded from the library of available protocols  Mpaka 2000 2000 Foxrobo device blocking DCI Evo control database pogwiritsa ntchito kulumikizana kwa Ethernet  Malo okhazikitsidwa  Malo a Gulu la G3 (zaukali). Oyendetsa I/O FBM iyi ndi gawo la generic Efaneti hardware momwe ma driver osiyanasiyana amapulogalamu amatha kuyika. Madalaivala awa amakonza FBM kuti izindikire protocol yomwe imagwiritsidwa ntchito ndi chipangizocho. Angapo madalaivala mapulogalamuwa ndi muyezo mankhwala zopereka. Madalaivala ena achizolowezi amatha kupangidwa kuti akwaniritse zosowa zenizeni. Madalaivalawa amatsitsidwa mwachangu ku FBM233 ndi pulogalamu yamapulogalamu yopangidwa kuti igwirizane ndi protocol ya chipangizo chachitatu. Njira zosinthira ndi zofunikira zamapulogalamu pa driver aliyense ndizosiyana ndi zida zomwe zikuphatikizidwa mudongosolo. ETHERNET LINK SETUP Kulumikizana kwa data pakati pa FBM233 ndi zida zam'munda ndi kudzera pa cholumikizira cha RJ-45 chomwe chili kutsogolo kwa gawo la FBM233. Cholumikizira cha RJ-45 cha FBM233 chitha kulumikizidwa kudzera pa ma hubs, kapena kudzera pa ma switch a Efaneti kupita ku zida zakumunda (onani ku “ETHERNET SWITCHES FOR USE WITH FBM233” patsamba 7). FBM233 imalumikizidwa ndi masiwichi a Efaneti kapena ma hubs kuti athe kulumikizana ndi chipangizo chimodzi chakunja kapena zida zakunja 64. CONFIGURATOR Wokonza FDSI amakhazikitsa doko la FBM233 ndi mafayilo a XML otengera kachipangizo kachipangizo. Zosintha zamadoko zimalola kukhazikitsidwa kosavuta kwa magawo olumikizirana padoko lililonse (monga, Dynamic Host Configuration Protocol (DHCP), ma adilesi a IP). Zosintha za chipangizocho sizofunikira pazida zonse, koma zikafunika, zimakonza zida zenizeni komanso mfundo zenizeni (monga, kuchuluka kwa scan, adilesi ya data yomwe ikuyenera kusamutsidwa, ndi kuchuluka kwa data yomwe ikuyenera kusamutsidwa pakachitidwe kamodzi). ZOCHITA Gulu lililonse la FBM233 litha kupeza zida zofikira 64 kuti muwerenge kapena kulemba zambiri. Kuchokera pa Foxboro Evo control station pomwe FBM233 imalumikizidwa (onani Chithunzi 1), mpaka 2000 Distributed Control Interface (DCI) kulumikizana kwa data kumatha kupangidwa kuti muwerenge kapena kulemba zambiri. Mitundu ya data yochirikizidwa imatsimikiziridwa ndi dalaivala yemwe wapakidwa pa FBM233, yomwe imatembenuza datayo kukhala mitundu ya data ya DCI yomwe yatchulidwa pansipa:  Kulowetsa kwa analogi kapena mtengo wotulutsa (chokwanira kapena IEEE poyandama molunjika chimodzi)  Kulowetsa kwa digito kumodzi kapena mtengo wotulutsa  Magulu angapo (odzaza) a digito kapena zotulutsa (zolowetsedwa m'magulu 32 olumikizana ndi mapointi a digito). Chifukwa chake malo owongolera a Foxboro Evo amatha kufikira milingo 2000 ya analogi I/O, kapena mpaka 64000 milingo ya digito ya I/O, kapena kuphatikiza kwa digito ndi analogi pogwiritsa ntchito FBM233. Mafupipafupi ofikira ku data ya FBM233 ndi malo owongolera amatha kukhala mwachangu ngati 500 ms. Kuchita kumadalira mtundu uliwonse wa chipangizocho komanso masanjidwe a data mu chipangizocho.
