1753-OB161753-OB161753-OB16PLC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。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————SVG/A***L859-0158-002#4SegmentMirrorAssyA***L4022.437.1455BoardSVGA***L/SVG4022.4022.456.2​982.2EirHeatExchangeA***L4022.436.2801SVGBoard/CardA***L4022.470.8125RHOptionSupplyRackROSRTECSEC-4400SeriesMassFlowControllerSEC-4400MTECSEC-4400SeriesMassFlowControllerSEC-4400MOpticalBeamSplitterCubePri***A***L/SVGOpticalItem854-0141-001A***LLithographyB.V.4022.502.25208BlueMirror/40ZeissBeleuchtungStarlith400A***L4022.455.84271ZeissBeleuchtungStarlith400A***L4022.455.84291HorizSituationINDModelRd.7004033169-902SperryKLATencorExtenderCard710-711345-00A***L4022.430.1800MotorAssy.TECSEC-4400SeriesMassFlowControllerSEC-4400MN2A***L4022.486.55123PressurizedGlassSVGTokyoElectronWZ10-100360-11TeachingJigWindowTELSVG/A***L879-0008-003OpticalAssy.A***L4022.431.3185.1LampOpticsLens106524-8007A***L4022.470.8825ModuleCardSVGA***L/SVG923-8244-001PowerSupply***CA***L4022.480.0101AWHGripperWristLPAssemblySVGTECSEC-4400SeriesMassFlowControllerSEC-4400MHeA***L4022.430.1422PowerPLModuleSVGA***L4022.430.6602BrushlessServomotorSVGA***L4022.471.68294ChannelAmpControlPPCAA***L/SVG4022.471.5027TCBSyncbusTriggZeissBeleuchtungStarlith500A***L4022.454.54492SVGA***L/SVG4022.502.29089EmissionDetectionAssyV.LSVG302-13393-00-1SpinChuckA***LSVGSpinChuckA***LA***L4022.471.4706SVGT.MeasurmentA***L4022.437.0218LEV.SENS.DEMONewLAM810-017004-1/81​0-017004R001SolenoidInterlockA***L4022.486.19531ABRUnitAT/XTPrecisionCryogenicLiquidNitrogenReservoirVesselNewLAM810-17016-001EtcherStepperMotorDriveMDCVacuumProductsCorp.K075-SBLM-4Global-Wulfsber​gSystemsDTU43000-01-01-3SVG/A***L859-9404-003VacuumChuckSVG/A***L879-0014-002VacuumChuckNewLAM605-017016-100PCBStepperMotorDriveChipLambdaAlpha1500WH07019PowerSupplyEZIDry20DryCompact2.0LamResearchWaferChuckKeyenceCorpPHOTOELECTRICSETLX-130RANDLX-130TA***L4022.436.46005Wafer&ReticleStageRackSVGManualGateValveHeliumLeakTestedHTEA***L4022.631.46912Bale1400ServoAssemblySVGKachinaSemiconductor16-3029-0012Plenum-ShowerTELA***L4022.484.72232AWHGripperWristLPAssemblySVGA***L4022.486.57153ATRSXT2SSYCoilAssemblySVGNikonOptistation3MSTPCB2S700-55(2S015-064-4)A***L/SVGModule4022..436.1064TokyoElectronSuscepter16-0126-007SUSC150mmon200A***L4022.486.5364OpticmirrorandsensorSVG)
