1756-IR6I1756-IR6I1756-IR6IPLC控制系统的故障诊断方法PLC控制系统故障的宏观诊断故障的宏观诊断就是根据经验，参照发生故障的环境和现象来确定故障的部位和原因。PLC控制系统的故障宏观诊断方法如下：■是否为使用不当引起的故障，如属于这类故障，则根据使用情况可初步判断出故障类型、发生部位。常见的使用不当包括供电电源故障、端子接线故障、模板安装故障、现场操作故障等。■如果不是使用故障，则可能是偶然性故障或系统运行时间较长所引发的故障。对于这类故障可按PLC的故障分布，依次检查、判断故障。首先检查与实际过程相连的传感器、检测开关、执行机构和负载是否有故障：然后检查PLC的I/O模板是否有故障：***后检查PLC的CPU是否有故障。■在检查PLC本身故障时，可参考PLC的CPU模板和电源模板上的指示灯。■采取上述步骤还检查不出故障部位和原因，则可能是系统设计错误，此时要重新检查系统设计，包括硬件设计和软件设计。※推荐品牌：※推荐公司Allen-Bradley厦门泰尼电气有限公司Schneider联系人：小黄（销售代表）Triconex固定电话：0592-6809319FOXBORO***:2917675397ABB邮箱：2917675397@***.comSIEMENS传真：0592-6890859MOTOROLA网址：www.xmtaini.comXYCOM地址：厦门海沧街道滨湖一里7号RexrothIndramat邮编：361026手机：18950191386MOTOROLAETHERNETMODULE64-W5401C02AAMETEKGEMCOSHUTHEIGHTMONITOR100/240VAC50/60Hz2BARCOBC-56343-32-62STEAMROTARYJOINT260PSI370USMOTORS1.5HPVARITRACACGEARMOTOR5:11730RPMSTIBEAMSAFEIITRAN***ITTERBSXAC&RECEIVERBS2RAC100CMLODESTAR1/4TONELECTRICCHAINHOIST230/460VSQUARED100AMPFSAFETYSWITCHSERIESF3240VACSTERLINGSPEEDPICKUPUNITMODELNo.7490-00-972-50DEUBLINROTATINGROTARYUNION6300-007-164HONEYWELLTEMPERATURECONTROLLERT915C19362LAMBGRAYSHARBORCO.AIRACTUATEDCYLINDER0361614SQUAREDCIRCUITBREAKERENCLOSURE120VSHUNT80AFCL3GEMSSURESITESTAINLESSSTEELLEVELINDICATOR50-1/2LEPILZRELAYPNOZX2.7P24VAC/DC50/60HZKEYENCEULTRA-ACCURATECCDLASERDISPLACEMENTSENSOR24GFSIGNETTYPE2536STANDARDMOUNTPADDLEWHEEL3.3-ERIEZUN-115-6A-FVHI-VICOMPACTELECTROMAGNETICFEGRACO1-1/4"102-929REDALERTFILTERHIGHPRESSUREREFURBISHEDSIEMENSGEARREDUCER20TO1RATIO21/2"SABBREPLACEMENTCIRCUITBOARDFORACH401600612VFDDRIVABBREPLACEMENTCIRCUITBOARDFORACH401600612VFDDRIVBAILEYDIFFERENTIALPRESSURETRAN***ITTER1242VDC36SQUARED600AMPROTARYHANDLEBREAKERBLAP3660042MMTMTETHREEPHASEACDRIVELINEREACTORRL-08013480-FOXBOROCHARTDRIVE24HR-9DAYWINDMVT725R125SIEMENS5HPELECTRICMOTOR213TCFR.200RPMTYPDYNACODY3000DYNACODERMODULECURLEEHAZARDOUSLOCATIONOVERHEADDOOROPERATORCONTROFISHERBAUMANN32-84DIAPHRAGMCONTROLVALVE3/4"1FANUCSERVOAMPLIFIERA06B-6058-H011GOULDSCENTRIFUGALPUMP1HP3PH1BF11034SQUAREDOMEGAPAK5HPACVFDDRIVE8803P00CO4FERHARDTLEIMERFR5001SENSORHONEYWELLR7249A1003UVAMPLIFIERFLAMERESP***EJAMESBURYMILWAUKEE2"ACTUATEDVALVEML124VAJCRANEDUO-CHEKII3"SSCHECKVALVEG60CPFREBUILTSTERLINGELECTRICACMOTOR460VAC.87HP19ZFBALLUFFBNS813-B06-R12-61-A-22-06SLITTERLIMITSWSTATEINDUSTRIALMETERINGPUMP120VAC.35AMP.63GPHMINFICONPCG410PIRANICAPACITANCEDIAPHRAGMGAUGEPSIEMENSAPOGEEAUTOMATIONANALOGPOINTEXPANSIONW/HOASIEMENSAPOGEEAUTOMATIONDIGITALPOINTEXPANSION8DI4BETACLOCKBASEDCHEMICALFEEDSYSTEM115VAC0.1AARNOLDWEILBURGLINKSFINEGRINDINGWHEELFORZ4AXARNOLDWEILBURGLINKSFINEGRINDINGWHEELMODELD15ARNOLDWEILBURGFINEGRINDINGWHEELMODELD1571390ARNOLDWEILBURGFINEGRINDINGWHEEL10"ODX3"IDARNOLDWEILBURGRECHTSFINEGRINDINGWHEELFORZ3AARNOLDWEILBURGFINEGRINDINGWHEELFORZ3AXISMODARNOLDWEILBURGVORSCHLIFFFINEGRINDINGWHEELFORARNOLDWEILBURGSAUMSCHLIFFFINEGRINDINGWHEELFORRVSI002-CM4000CAMERAWITHPARKERDAEDALMANUALPOSITIAO***ITHADJUSTABLESPEEDDRIVEMOTOR1/4HP1725RPM90WESTINGHOUSECIRCUITBOARDMODEL7379A13MGWLAUDAM3WATERBATHMGWLAUDATYPEMSSQUAREDSIZE0FUSIBLECOMBINATIONMOTORSTARTER9BRISTOLAIRCONDITIONINGCOMP.H258B18QABCA230VABBKENTTAYLORSPRTRAN***ITTERX571TB01132A0100-0015DABBLOWVOLTAGEMOTOR480VOLT750RPM3GAA114001-AORMECSERVOMOTORMAC-DB100P/ADODGETIGEAR-2GEARREDUCER40:1RATIO0.6HP1750FISHERPROVOXDM6004X1-EA2MPUROMBOARDCRIMISCX1-A3ALLENBRADLEYPUSHBUTTONENCLOSURE800H-2HAD10R78SENSOTECLOADCELLMODEL#31/1434-02PART#060-14MERLINGERINNSF150N150AMPCIRCUITBREAKERDISCONNECCUTLERHAMMER30AMPFSAFETYSWITCH600VAC3PHASSQUAREDMAL364001021CIRCUITBREAKER400ASHUNTTRIPASHCROFTPRESSURESWITCHB722SX06PASABANELECTRONICAPOSITIONINGDISPLAYPG-4262WIN***ITHSEENCOREW/WINGUARDE35MSTS30:1RATIOFPALLHYDRAULICFILTER9660D22"LONGHANNIFINPNEUMATICCYLINDERBORE5CBB-A10CSTROKE12WARNERELECTRICUM210-3040CLUTCH90VDC5371-271-008GEFANUCVERSAMAXIC200MDL750E24VDC32PTIC200MDBALDOR1/2HPDCMOTOR90VDC1750RPM56CFRAMEMON-TRON305FX-STINDUSTRIALETHERNETSWITCHNTRON30ESILASERMATRIXCONTROLMODULECKA55116APVPUMPREPLACEMENTROTORLOBE30HX420146900218DEPRAGSTATIONARYSCREWDRIVERWITHTORQUESENSORHONEYWELLSERIALLINKMODULE621-99396219939OMEGAOMEGADYNEHIGHACCURACYL***02-500LOADCELL0-500TACZONECONTROLLERMR88R-CE-T-NCHAR-LYNN103-1004-010HYDRAULICMOTORABBYYT102GCIRCUITBOARDYT212001-AP/4ROSS466C79151LOCKOUTMONITORWESTINGHOUSE2D78548G04ELECTRONICMONITORIIW/IPONIIDECIZBARLIBR***102FMCPU&FANUCA058-2308-C041MTSTEMPOSONICSTTMRBM0650RLINEARDISPLACEMENTTRATOYOOKITOYO-OKIVARIABLEVOLUMEHYDRAULICPUMPHPP-VD2WEIDMULLER492-X.270PRECITECPREAMPLIFIERLASERMATSQUAREDLH36400CIRCUITBREAKER400AMPI-LINESQUAREDLH36400400AMPI-LINECIRCUITBREAKERINTERRUSQUAREDMOD5SIZE3STARTERMCC***ETFSWITCH)
