1762-OW161762-OW161762-OW164）程序执行根据PLC梯形图程序扫描原则，按先左后右，先上后下的步序，逐句扫描，执行程序。但遇到程序跳转指令，则根据跳转条件是否满足来决定程序的跳转地址。若用户程序涉及到输入输出状态时，PLC从输入映象寄存器中读出上一阶段采入的对应输入端子状态，从输出映象寄存器读出对应映象寄存器的当前状态。根据用户程序进行逻辑运算，运算结果再存入有关器件寄存器中。5）输出处理程序执行完毕后，将输出映象寄存器，即元件映象寄存器中的Y寄存器的状态，在输出处理阶段转存到输出锁存器，通过隔离电路，驱动功率放大电路，使输出端子向外界输出控制信号，驱动外部负载。（3）PLC的运行方式：1）运行工作模式当处于运行工作模式时，PLC要进行从内部处理、通信服务、输入处理、程序处理、输出处理，然后按上述过程循环扫描工作。在运行模式下，PLC通过反复执行反映控制要求的用户程序来实现控制功能，为了使PLC的输出及时地响应随时可能变化的输入信号，用户程序不是只执行一次，而是不断地重复执行，直至PLC停机或切换到STOP工作模式。注：PLC的这种周而复始的循环工作方式称为扫描工作方式。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！！！————————————————————————————————AllenBradley1771-ESServoExpanderModule1771ESUsedReliance0-49001-5CardpakPowerSupply0490015NewGiddings&Lewis502-03840-23-R0ServoEnc502-03840-23BOSCH1070075698-104PROFIBUS-WS-MOD​ULEDIN19245T1+2FoxboroD0130FH-CControlBoardToyotaCorolla8910IA091222000​5S60N***igationEntertaiRELIANCEELECTRIC0-48675DV/DTNETWORKFIELDCARDRELIANCEELECTRIC0-51831-6CVTGCURRENTVOLTAGECARDRelianceElectric8647511RStackRectifier86475-11RHoneywellW7100G1001ChillerDischargeWaterControlDanfossVLT3000VFDACVaribleSpeedDrive175H1730YokogawaADMAGAM11-ASA1A--000MagneticFlowConverterBaldorID15H201-EACVFDSpeedDrive230VID15H201EGEFanucIC500-CB524MArithControlIC500CB524MNewButlerAutomaticDC23947-558ControlBoardDC23947558RelianceElectric2GU21001ACVFDSpeedDriveGP-2000Liebert4D10286ControlCardNewRELIANCEELECTRIC0-52002-2RELAYCARD0520022NEWQuatroAutomationGroupServoMotor210-2019-001QA03BGiddings&Lewis502-03417-03ServoControl5020341703GEFanuc44A719348-104-R​04AX503Axis44A719348104ABBA145-30-22-80Contactor220-240V3PA16302280NewMagnetrolTA1-0201-110MassFlowTran***itterTA10201110CooperCrouse-HindsETH2703ProjectorHorn120VNewAllenBradley1747-L20CProcessor1747L20CNewOmronR88M-H20030-G25​BJS1ACServoMotorNewAllenBradley1333-AABVFDACSpeedDrive1333AABNewRelianceElectric0-52850IRFADriveCardNewRelianceElectric0-52851CSSADigiCardSequencingNewAllenBradley50387-002ModulatorLogic50387002New***CVV5Q41-0703NSG-​CDWMFLDPLUG-INVV5Q410703NSGCD​WRELIANCEELECTRIC0-51847-4VLDEVOLTAGEDETECTORCARDRelianceElectric0-52862-CDriveBoard052862CNewGiddings&Lewis502-03417-03572-03417-09M.1017.6009Giddings&Lewis502-03417-02ServoControl5020341702AllenBradley1771-HSN/BServoController1771HSNNewFoxboroD0130FR/CControlBoardD0130FRNewRelianceElectric0-51811-3TesterCardPCBoardNewMonarch9460SierraSport2ThermalPrinterM09460MJRAdvancedMicroControls1531InterfaceResolverModuleALLENBRADLEY22DJ9-4000TIMEDELAYCONTROLMODULE-NEWAllenBradley1794-OF4IIsolatedAnalogOutput1794OF4IAdept30400-20000SignalInterfaceBoxforRobotAllenBradley1771-IKEncoder/CounterModule1771IKNewRelianceElectric0-51849-1GateDriverControl0518491OmronC200HW-SLK23SymacLinkUnitC200HWSLK23HBMMC-01***01-120/07AmplifierCardMC01NewGETJJ436225CircuitBreaker225AMP3P600VoltNewAllenBradley1771-DCM/BCommunicationModule1771DCM/BAllenBradley1771-KRFBroadbandCommModule1771KRFEdwa***5520D-AWSignalingDuotronicHorn/SirenNewABB10D1475SN04PF29​KC51C1112C1DigitalFlowMeter1/4"LiftMasterLA40024VDCLinearGateOpenerLiftMasterFisher39A8571X042-79SerialInterface39A8571X04279FisherRosemount41B5229X052PowerConvertCP6701X1-A4)
