REDUNDANT ANALOG OUTPUTS Ib qho rov ua haujlwm analog tso tawm ua haujlwm thaiv, AOUTR, yog siv rau txhua khub ntawm cov khoom tawm. Lub AOUTR thaiv tswj cov ntaub ntawv sau tawm thiab pib cov logic rau cov channel tsis tu ncua. Nyob rau txhua lub voj voog ua tiav cov ntawv sau tau zoo ib yam raug xa mus rau ob lub modules, tag nrho kev siv lub fieldbus thiab logic circuitry ntawm txhua module. Thaum kuaj pom qhov tsis ua haujlwm hauv ib qho ntawm cov modules, nws cov zis tau tsav mus rau 0 mA thiab cov channel sib txuas hauv cov qauv zoo tau txuas ntxiv muab cov khoom siv tam sim no. Txhua qhov tso zis channel tsav ib qho kev thauj khoom sab nraud. Transmitter hwj chim los ntawm txhua lub module yog diode LOSSIS ua ke nyob rau hauv lub redundant adapter kom paub tseeb tias redundant zog. Lub microprocessor ntawm txhua qhov module ua tiav cov analog tso tawm daim ntawv thov kev pab cuam, ntxiv rau cov txheej txheem kev nyab xeeb uas siv tau rau kev noj qab haus huv ntawm lub module. Configurable options in the modules include Fail-Safe Action (Tuav/Fallback), Analog Output Fail-Safe Fallback Data (ntawm ib lub hauv paus channel), Fieldbus FailSafe Enable, thiab Fieldbus Fail-Safe Delay Time. Analog Output Fail-Safe Fallback Data xaiv yuav tsum tau teem rau 0 mA tso zis. Qhov no tshem tawm ib qho ntawm ob khub ntawm cov khoom tso tawm los ntawm kev pabcuam rau cov teeb meem tshawb pom xws li module tsis tau txais cov ntawv sau tau zoo, lossis tsis dhau qhov kev ntsuam xyuas kev ruaj ntseg ntawm FBM microprocessor sau rau cov ntawv tso tawm. Kev teeb tsa ntawm Analog Output Fail-Safe Fallback Cov Ntaub Ntawv xaiv rau 0 mA cov zis kuj txo qis qhov ua tau ntawm qhov tshwm sim "tsis ua haujlwm siab". PHYSICAL DESIGN FBM237 muaj cov qauv tsim qauv, nrog rau cov rugged extruded aluminium sab nrauv rau kev tiv thaiv lub cev ntawm cov circuits. Enclosures tshwj xeeb uas tsim los rau mounting FBMs muab ntau theem ntawm kev tiv thaiv ib puag ncig, mus txog ib puag ncig hnyav (Class G3), raws li ISA Standard S71.04. HIGH RELIABILITY Lub redundancy ntawm module khub, ua ke nrog cov kev pab them nqi siab ntawm faults, muab ib tug heev subsystem muaj sij hawm. Ob lub module nyob rau hauv lub redundant khub tej zaum yuav raug hloov yam tsis muaj kev ntxhov siab nyob rau hauv lub teb tso zis teeb liab mus rau lub zoo module. Lub module tuaj yeem raug tshem tawm / hloov pauv yam tsis tau tshem tawm cov khoom siv hluav taws xob tshem tawm, lub zog, lossis kev sib txuas lus cable. VISUAL INDICATORS Lub teeb-emitting diodes (LEDs) muab tso rau hauv pem hauv ntej ntawm lub module muab kev pom zoo qhia txog kev ua haujlwm ntawm fieldbus module. FIELDBUS Kev Sib Txuas Lus A Fieldbus Communications Module lossis Tus Txheej Txheem Tswjhwm cuam tshuam rau qhov rov ua dua 2 Mbps module Fieldbus siv los ntawm FBMs. FBM237 lees txais kev sib txuas lus los ntawm ob txoj hauv kev (A lossis B) ntawm 2 Mbps Fieldbus - yog tias ib txoj hauv kev tsis ua haujlwm lossis raug hloov mus rau theem system, lub module txuas ntxiv kev sib txuas lus ntawm txoj kev nquag. MODULAR BASEPLATE MOUNTING Lub module mounts ntawm Standard Modular baseplate, uas haum mus txog yim Fieldbus Modules. Lub Modular baseplate yog DIN rail mounted los yog khib mounted, thiab muaj xws li cov teeb liab connectors rau redundant Fieldbus, redundant ywj siab dc zog, thiab txiav cables. Cov khoom siv rov ua dua yuav tsum nyob rau hauv ib sab PSS 31H-2Z37 Page 3 odd/txuas txoj hauj lwm khub ntawm lub hauv paus (txoj hauj lwm 1 thiab 2, 3 thiab 4, 5 thiab 6, los yog 7 thiab 8). Txhawm rau kom ua tiav cov txiaj ntsig rov qab, ib qho kev hloov pauv hloov pauv hloov pauv tau muab tso rau ntawm ob qho tib si hauv qab lub hauv paus kev txiav tawm cable txuas los muab ib qho kev txiav cable txuas (saib daim duab 1). Ib qho kev txiav tawm ib leeg txuas los ntawm cov khoom siv rov qab mus rau qhov txuas TA. Rau cov ntawv thov configurator thiab rau lwm lub tshuab saib xyuas los ntawm SMON, System Manager, thiab SMDH, redundant FBM237 modules zoo nkaus li cais, tsis muaj kev cuam tshuam. Kev ua haujlwm rov ua haujlwm rau cov modules no yog muab los ntawm lawv cov kev tswj hwm cuam tshuam. TERMINATION ASSEMBLIES (TA) Field I/O signals txuas mus rau FBM subsystem ntawm DIN rail mounted termination assemblies. Cov TAs siv nrog FBM237 tau piav qhia nyob rau hauv "TSHIAB ASSEMBLIES THIAB CABLES" ntawm nplooj 7.
