1746-OA161746-OA161746-OA16尽管梯形图与继电器电路图在结构形式、元件符号及逻辑控制功能等方面相类似，但它们又有许多不同之处，梯形图具有自己的编程规则。1）每一逻辑行总是起于左母线，然后是触点的连接，***后终止于线圈或右母线（右母线可以不画出）。注意：左母线与线圈之间一定要有触点，而线圈与右母线之间则不能有任何触点。2）梯形图中的触点可以任意串联或并联，但继电器线圈只能并联而不能串联。3）触点的使用次数不受限制。4）一般情况下，在梯形图中同一线圈只能出现一次。如果在程序中，同一线圈使用了两次或多次，称为“双线圈输出”。对于“双线圈输出”，有些PLC将其视为语法错误，***不允许；有些PLC则将前面的输出视为无效，只有***后一次输出有效；而有些PLC，在含有跳转指令或步进指令的梯形图中允许双线圈输出。5）对于不可编程梯形图必须经过等效变换，变成可编程梯形图。6）有几个串联电路相并联时，应将串联触点多的回路放在上方，如图5-2a所示。在有几个并联电路相串联时，应将并联触点多的回路放在左方，如图5-2b所示。这样所编制的程序简洁明了，语句较少。★厦门泰尼电气有限公司★★联系人：小黄★★QQ：2917675397★★电话：0592-6809319★★手机：18950191386★★传真：0592-6890859（注小黄收）★★邮箱：2917675397@***.com★★地址：厦门市海沧区海沧街道滨湖一里7号2008室★InstekPR-6030LaboratoryDCPowerSupplyVicorMegaPACMP5-75549PowerSupplywith4InputsE49EMGEUPSSystemsPulsarEXB1000/150068185KOLLMORGENSERVOMOTOR160VDCWandel&GoltermannW&GBN9305/00.10LineInterfaceE2GRANVILLEPHILLIPS275CONVECTIONGAGEDIGITALGRANVILLEPHILLIPS275CONVECTIONGAGEANALOGSusumuTFL0816-5N65000PCSAlcoADF05s300PCSAMPCrimpingTool90131-1TypeF#46POWERTECHDRIVE-AXMOTORTYPE56.05(40/02/18)HP/Agilent37722ADigitalTelecomAnalyzeropt005TYCOAMP42037CONNRING18-22AWG#6TINCRIMP5375PCSLEITCHRC2000ES2000/3000EXPANSIONSYSTEMSCHNEIDERMODICONPC-A984-1418KMEMCPUMODULESquareDHe***yDutySafetySwitchSeriesE1Tektronix7T11SamplingSweepPlugInUnit3M/HitachiWL-201WideAngleConversionLensWL201AlphaWireTinnedCopperTubularBraiding#2173100ftAmrelPPS-10710ProgrammableDCPowerSupply3COMSuperStack34400Switch3C1720324-portSwitchParker1/4"ComboUnit#06A11A13ABRCGEFanucIC692CPU211CCPUModule+IC692MDR541CNECTC5000EX10VIDEOCONVERTERGELinkPDGELPDA024D01A***artDistributedSystemLCoselPowerSupplyPAA300F-2424V14A100-240VAC4.4AKulicke&SoffaControllerModel4322BaldorDodgeTigear217Q30L56GearReducer30:1Dayton4Z134APermanentMagnetDCGearmotor18RPM90VHP1660ASLogicAnalyzer/OscilloscopeE4EABC121NMNanomotionAB1ADriverBoxAB1A-2-HR-E16NCNor-Cal030905-2-14+SS-4H-TW+31E1VacuumWandel&GoltermannW&GBN9305/90.46DS3ATMInterfaceLambdaLPT-7202-FMTripleOutPowerSupply0-7/0-20V5APower-OneSPM5A2A1L5VDC35A/5VDC150APowerSupplyEMitsubishiCC-LinkMELSECAJ65SBTC1-32D1InputUnitAccu-Sort10BarCodeScanner10Z30-05-ZZLambdaUltraFlexUBZ2HHXXX-2075PowerSupply5V60AOmronD5M-5BContactLinearDisplacementSensorLocLambdaLQD-421DualPowerSupply0-20V1.7AAMP45707-2CrimpingTool#47Tektronix475OscilloscopeE44DABC1058Racal-DanaSeries9000MicroprocessingTimer/Counter***CPneumaticsMSX16-125PneumaticSlide125mm0.15-0.7Keithley70674-Wire10-ChScannerCardMKS244CONTROLLERSencoreVA62AUniversalVideoAnalyzerEdmundIndustrialOptics45200BSCube20mmBeamSplitSpectralDynamicsSD105AAmplitudeServoMonitorE26BAHalcyon548ADataTestSet+front&backcoverSquareDSYMAX5-SlotRack8030RRK1008030-RRK-100E47DBrowning207SCA-S207SCASReducerAdvancedMotionControlsDQ111EE15A40LDCServoDriveION5810SAlphaCriticalEnvironmentIonizerBlowerLHResearchMMAX63Mighty-Mite-APowerSupply15V33ASuperiorElecPowerstat126VariableAutotransformerMurataGRM43RR72A224KA?01L1000PCSOaktonColeParmerHygrothermograp?hEW-37250-00Macom7N264-S03325PCSPanasonicECJ1VC1H101J3280PCSVWR35519-020Hygrometer/Thermometer/dewpt.w/ProbeDanaherKollmorgenS20630-VTSServoAmplifierS200E44DSOLASLR-10H-480-3Line/driveReactor14AAnorad5413KeyboardAND/PurdyAND-TFT-8PA-KIT8"LCDPROTOTYPINGKITTENMA72-7260SoundLevelMeterCalibratorKEMET494D475K050AT500PCSLEYBOLDQUADREX100SCU901-200-G6MASSFILTERCONTROLMKSBarartronType141141AA-00002CB2TORRE31AMPC-ABSTACO1020CTVariableautotransformer240V50/60HZ,ABCMotorola/***emiMMDF7N02ZR2500PCSCTI30ftHeliumHose8043074G360260PSI8043074G360Allen-Bradley1606-XL60DRAC/DCRedundantPowerSupplyAllenBradleyModel1785-L30BAPLC-5/30ProcessorModABAllenBradleyPLC5/11Processor1785-L11BSeriesCBeckmanDU70DU-70Spectrophotomet?erforParts/orRepaNationalInstruments777854-044-chRS232185729D-01E3CTIGroundMasterCTC065/CTC065RTJFFluke801HDifferentialDCVoltmeterEmersonUSElectricalMotorsE871ProcessTran***issionBarber-ColmanMF-482-105-1/71?7498-11Actuator120V28WTektronix465OscilloscopeAMP90123-2-GCrimpingToolTypeF#352AcopianVA3-3NT220M13241850-02PowerSupplyNarrowKeithley7001SwitchingSystem+7017Card7017-102-02BAlphaWireTinnedCopperBraidSleeving#2174100ftSquare-DSeriplex9001AEQ343B24VDCControllerF.W.BellUM-77001000AClampOnCurrentPowerProbeE3LeyboldQuadrex-100SCU901-200-G6MassFilterControlEAMP18-1646216Crimper602LessonIronManGearBox#W8213010.00HP400EL400-ELACVoltmeter1mW600ohmRMSVoltsSquareDVigirexRH99PGround-FaultRelay220/240VSchneiderDEP218/AS-BDEP-?218InputModule115VAC16ptTTCJDSUActernaBoard80-44808-01MeanWellMWPSP-1000-1212V-75A12V-66.4ACiscoC***3015SeriesConcentrator***3000E24DABC13AT&TLucentDDM-2000OC-3ShelfAssemblyMainframeAMP59459CrimpingToolTypeC#619E49CABC5131Tektronix7S11SamplingUnitAMPCrimpingTool47907TypeC#434AMPCrimpingTool90331-1-BTypeF#358AMPCrimpingTool90269-1#384HP3488ASwitchControlUnitE33CABC1425OmronS3D8-CKF-USSensorControllerS3DCKFUSRemovedfr***CPneumaticsN***2000-N02-5DZ/NAW2000-N02-C/NVHS20Yokogawa235410-700211DPM/12354-101ph2wireE27AABXPPowerfleXPowerXM7-3W3W2P-1200?02PowerSupply48VFluke8200ADigitalVoltmeterPhoton,IncBeamScan1080ControlUnitE44DABC260GEMotor5KH35KG430E
