1794-OB16P1794-OB16P1794-OB16P可编程控制器的工作过程包括两部分：自诊断及通信响应的固定过程和用户程序执行过程，如图5-1所示。PLC在每次执行用户程序之前，都先执行故障自诊断程序、复位、监视、定时等内部固定程序，若自诊断正常，继续向下扫描，然后PLC检查是否有与编程器、计算机等的通信请求。如果有与计算机等的通信请求，则进行相应处理。当PLC处于停止（STOP）状态时，只循环进行前两个过程。而在PLC处于运行（RUN）状态时，PLC从内部处理、通信操作、输入扫描、执行用户程序、输出刷新五个工作阶段循环工作。每完成一次以上五个阶段所需要的时间称为一个扫描周期。◆企业名称：厦门泰尼电气有限公司◆主营业务：DCS,PLC◆经营模式：贸易◆贸易地区：***◆联系人：小黄《女士》◆电话：0592-6809319◆手机：18950191386◆***:2917675397◆传真：0592-6890859（备注“01006”收）◆E-mail：2917675397@***.comAPPLIEDMATERIALSENDURA5500PWRDISTMOD.,0205-00782APPLIEDMATERIALSENDURA5500PWRDISTMOD.,0170-20398APPLIEDMATERIALS8300PARTSAppliedMaterialsPromBoard670774APPLIEDMATERIALSCLAMPBLADDER0020-79092NEW,SEALEDAppliedMaterialsSupportCassette0020-28435RevPBAppliedMaterialsSeriplexSensorBusAPPLIEDMATERIALSHOUSING,EXT.INTPWB-0100-00045AMATAppliedMaterialsRFCable0620-00499newAppliedMaterials0020-34742CenteringPlate150MMNewAppliedMaterialsPWBAssyPromTriplePage670794APPLIEDMATERIALSCABLEINT.FARADYCAP70512332100AppliedMaterialsAMATCoverPlateExhaust0020-37817AMATAPPLIEDMATERIALSCHAMBEREXHAUSTPOCKETSHIELDNEWAMATAPPLIEDMATERIALSVALVEGATESEAL35x336mmAppliedMaterialsHDPESCChuck200MMNEW-APPLIEDMATERIALSDIOLOADINGBOARD200113D01NEWAMATAPPLIEDMATERIALSGASDISTRIBUTIONPLATE,133AMATAPPLIEDMATERIALS0021-25014DISKSHUTTERBESCPINAppliedMaterialsCapacitancePiraniGaugeCDG/PiAppliedMaterialsAMATH2/N2/HEGasLine0050-25218NewAppliedMaterialsPraxairAmpouleBubbler,0195-02636AMATAppliedMaterialsHeatExchangerAMAT0workingAMATAppliedMaterialsHeatExchanger0010-70027AppliedMaterialsHDPCH.ESC200MM,CompleteAssy.AMATAppliedMaterialsP5000MarkIICVDReactor200mm12AssortedAppliedMaterialsCableAssembliesNEWAPPLIEDMATERIALSBOARD5-CHANNELHPRE70512710000NEWAppliedMaterialsSystemElectronicsPCB0100-20001AppliedMaterials1270-90086SwitchFlow1/2"NPTAppliedMaterialsCoverRing300MM0021-16783NEWAppliedMaterialsAMAT0020-00249SlitSapphireAppliedMaterialsRFFixedMatchAppliedMaterialsTurboPumpCableAssy0150-36038NEWAppliedMaterialsAMAT0040-33998ChamberUpperLinerAFC550AppliedMaterialsGasMassFlowControllerNewAppliedMaterials0150-04244CableAssyMirraWaferAppliedMaterialsElectrostaticChuckCover9999-00178AppliedMaterials0200-00402IsolatorPumpingRingAppliedMaterialsAMAT0150-70002CableFlatAssySCSIAppliedMaterialsSlitValve0020-20340AMATVMECounterBd.Board0100-00012AppliedMaterialsAMATAPPLIEDMATERIALSSHOWERHEADPERFPLATE0021-35869AMAT0040-02609SuperELowerLinerAppliedMaterialsAffinityChillerAppliedMaterialsAMATCWA100KMP21CBD2AppliedMaterialsCoverRing300MM0021-16783NEWAppliedMaterials50'CableFUPStoACRack0150-088767AppliedMaterialsBallBearingsCleanRoom3060-01183APPLIEDMATERIALSSEALCTRRINGASSY3700-01626(LOT-4)AppliedMaterialsAMAT0021-09104CathodeLowerLinerAppliedMaterialsVMEBoardFOLC0660-90093AppliedMaterials0020-09618Bushing,PlugAppliedMaterialsDynamicSeal3700-02333AMATAPPLIEDMATERIALSSPINSCANCONTROLLER0090-91494XR80AppliedMaterialsProducerFaceplate0021-03637AMAT0020-05384BESCShutterDiskAppliedMaterialsAppliedMaterials0200-10191CommonSilaneShieldAppliedMaterialsAMAT3710-01095ShaftHSGRollerAssyAppliedStrengthofMaterialsbyFa-HwaChengAMATAPPLIEDMATERIALS0010-20098CHASSISASSYNEWAppliedMaterials/AMATShieldBowlPN:0020-2716020AppliedMaterialsCleanRoomLensSupport0020-21697AppliedMaterialsAMAT950812MonitorPlugAssyAppliedMaterials0200-00403IsolatorPumpingMiddleAppliedMaterialsAMAT0010-70131Position58"ChamberAppliedMaterialsAMAT0021-10223ChamberUpperLinerAppliedMaterialsGreentweed9217-SC513O-RingAMATEllipsometerIIbyAppliedMaterialsNEWAppliedMaterials/AMATShieldBowlPN:0020-29347AppliedMaterialsAMAT0020-09374LargeFaceSealAppliedMaterialsAMATBallBearing0190-00763(Qty2)APPLIEDMATERIALSWAFER,8"ALN,NOTCHWxZ-NEWAppliedMaterialsAMAT0020-97794SpacerBlade100-150AppliedMaterials0010-22161EnduraE-CleanESCMatchAppliedMaterials2PositionDPSDataSwitch1270-01686AppliedMaterialsADOAutomaticDoorOpener0190-02751AppliedMaterialsAMATP-5000,MarkII,DualchamberAppliedMaterialsDualDiodeDetector0190-10025ADP22AppliedMaterials0020-38061CathodetoLANInsuatorAppliedMaterials0020-20114DCBiasIsolatorAppliedMaterialsBrooksAutomationFixload25LoadportLEYBOLDMAG400CTAPPLIEDMATERIALSAMAT0190-71355AnalogPCBAppliedMaterialsAMATSeriplexAPPLIEDMATERIALS0200-09347A,AMATCOLLAR150MMFLAT)
