A:正确B:错误答案:错误ThetransistoroutputPLCcanonlycontrolthelow-voltageDCcircuitof24VDC×300mA,withsmalldrivingcurrent,highoperationfrequencyandlongservicelife.（）

A:错误B:正确答案:错误Theconnectionofrotaryencoderusedinsortingunitisasfollows:①thewhiteoutgoinglineisphasealine,greenoutgoinglineisphaseBline.②Thepositivepowerlead(red)oftheencodermustbeconnectedtothe+24Vregulatedpowersupplyterminalofthedevicesideconnectionport,whichisnotbeconnectedtothepowerterminalVccwithinternalresistance.（）

A:错误B:正确答案:错误ThewritingorforcedoutputofsoftcomponentstatusmayleadtothechangeofPLCcontrol.Safetymustbeconfirmedbeforeimplementation.Takingthistrainingactivityasanexample,itisrequiredtocleartheworkpieceinthefeedingunitsilobeforethetest,otherwise,whenthelowerpushingcylinderisforcedtoextend,thepistonrodwillbestuckbytheworkpieceafteritisextended.（）

A:错误B:正确答案:正确TheFX3UandH2UseriesPLCbasicunitswithtransistoroutputhavebuilt-inpositioning（）

A:正确B:错误答案:正确Thedistancesettingphotoelectricswitchismainlybasedontrigonometricdistancemeasurementandhastwodetectionmodes:BGSandFGS.BGSmodeisusedtodetecttheowingandshortageofmaterials.Inthismode,thematerialsbetweenthesensorandthesetdistancecanbedetected,andthebackgroundmaterialsbeyondthesetdistancecannotbedetected,soastorealizethepurposeofdetectingtheworkpieceinthetransparentplasticpipe.（）

A:正确B:错误答案:正确Theairfilter,pressurereducingvalveandoilatomizerareoftencombinedIntheindustrialpneumaticsystem.Thecomponentsareconnectedbymodularcombinationtoformapneumatictripleunit,whichisusedastheairsourcetreatmentdevice.（）

A:错误B:正确答案:正确PLCofFXH2Userieshavebuilt-in21pointhigh-speedcounteRC235-C255,whichareall32-bitcounters.Comparedwiththeordinarycounter,thehigh-speedcounterisusedtocounttheexternalpulsewhosefrequencyishigherthantheinternalscanningfrequency.Duetothehighfrequencyofthecountingsignal,FX3Uuseshardwarecountingorinterruptmodetocount,whichisindependentofthescanningcycle.H2Uiscountedininterruptmode.（）

A:错误B:正确答案:错误Beforeprogramming,atestprogramshouldbewrittenandruntotestthepulsenumberofeachspecificpositionontheconveyorbelt(includingthecenterpositionofeachpushercylinderandtheexitpositionofthedetectionarea)toobtainthecoordinatevalueofeachspecificpointtothefeedinletcenterpointasthereferenceorigin.Whenthecontrolprogramisfurthercompiled,thecoordinatevaluedataobtainedfromthetestisstoredastheknowndatafortheprogramtocall.（）

A:错误B:正确答案:错误Fromtheworkingprocessofsortingunit,theprogrammingofhigh-speedcounteronlyrequiresthatitcanreceivethepulsesignalofrotaryencoderforcounting,providethedisplacementinformationofworkpieceontheconveyorbelt,andresetthehigh-speedcounterused.Themorecomplexfunctionsofhigh-speedcounter,suchasinterruptprocessingwhenpresetvalueisreached,arenotneeded.（）
