1762-MM1RTC1762-MM1RTC1762-MM1RTCPLC有两种基本的工作模式，即运行(RUN)模式与停止(STOP)模式。在运行模式，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。除了执行用户程序外，在每次循环过程中，PLC还要完成内部处理、通信处理等工作，一次循环可分为5个阶段（见图1-5）。PLC的这种周而复始的循环工作方式称为扫描工作方式。由于计算机执行指令的速度极高，从外部输入-输出关系来看，处理过程似乎是同时完成的。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！！！————————————————————————————————GENERALELECTRICDS3827BP6A2EFADUSPPDS3827BP6A2EFADGeneralElectricDS3820PSCC1D1BPowerSupplyGENERALELECTRICDS3810CLCBUSPPDS3810CLCBGeneralElectricDS3800HCVA1H1GCircuitBoardNEWGENERALELECTRICDS3815PMMA1F1BUSPPDS3815PMMA1F1BGeneralElectricDS3800HMPK1N1KCPUBoardNEWGENERALELECTRICDS3810MMACUSPPDS3810MMACGENERALELECTRICDS215SLCCG2AZZ0​1BNSPPDS215SLCCG2AZZ0GENERALELECTRICDS3860HUMBNSFPDS3860HUMBGENERALELECTRICDS3820PMMB1A1BUSPPDS3820PMMB1A1BGeneralElectricDS3800HLNE1B1BCircuitBoardUSEDGeneralElectricDS3810CLCB1A1ACircuitBoardUSEDGENERALELECTRICDS3800HMPC1F1DNSFPDS3800HMPC1F1DGENERALELECTRICDS215KLDCG1AZZ0​3BNSFPDS215KLDCG1AZZ0GeneralElectricDS3800HFPG1E1EDriveCPUBoardGENERALELECTRICDS3820MSAB1A1ANSPPDS3820MSAB1A1AGeneralElectricDS3800NDIDICircuitBoardGENERALELECTRICDS3820LIMAUSPPDS3820LIMAGENERALELECTRICDS200GDPAG1AKFNSFPDS200GDPAG1AKFGeneralElectricDS3800NMEA1P1KCircuitBoardNEWGENERALELECTRICDS3800HUMA1B1CUSPPDS3800HUMA1B1CGENERALELECTRICDS3860NVCDNSFPDS3860NVCDGENERALELECTRICDS3800NRTB1AUSPPDS3800NRTB1AGENERALELECTRICDS215SDCCG1AZZ0​1BUSPPDS215SDCCG1AZZ0GENERALELECTRICDS3800HCMBNSPPDS3800HCMBGENERALELECTRICDS3800HMPC1G1DUSPPDS3800HMPC1G1DGENERALELECTRICDS3800HPBDUSPPDS3800HPBDGENERALELECTRICDS215DMCBG1AZZ0​3BUSPPDS215DMCBG1AZZ0GeneralElectricDS3800HAIC1A1APCBoardUSEDGENERALELECTRICDS3800NMEA1G1EUSPPDS3800NMEA1G1EGENERALELECTRICDS3800NMEA1H1EUSPPDS3800NMEA1H1EGENERALELECTRICDS3800NMEA1P1KUSPPDS3800NMEA1P1KGENERALELECTRICDS3820MAUA-1B1AUSPPDS3820MAUA1B1AGEGeneralElectricDS200PCCAG9ACBPowerConnectCardGENERALELECTRICDS3800HRRBUSPPDS3800HRRBGeneralElectricDS200LDCCH1ANACircuitBoardNEWGENERALELECTRICDS3800HAIA1E1DUSPPDS3800HAIA1E1DGENERALELECTRICDS3800HLND1C1CUSPPDS3800HLND1C1CGENERALELECTRICDS3800HLND1B1BUSPPDS3800HLND1B1BGENERALELECTRICDS200IMCPG1AAAUSPPDS200IMCPG1AAAGENERALELECTRICDS200IMCPG1ADAUSPPDS200IMCPG1ADAGENERALELECTRICDS200IMCPG1AEAUSPPDS200IMCPG1AEAGENERALELECTRICDS200IMCPG1CBAUSPPDS200IMCPG1CBAGENERALELECTRICDS200IMCPG1CCBUSPPDS200IMCPG1CCBGENERALELECTRICDS3820MAUDNSPPDS3820MAUDGENERALELECTRICDS200PCCAG8ACBUSPPDS200PCCAG8ACBGeneralElectricDS3800HXPD1B1DCircuitBoardNEWGENERALELECTRICDS3800NHVEUSPPDS3800NHVEGENERALELECTRICDS3800NHVE1C1AUSPPDS3800NHVE1C1AGENERALELECTRICDS3800NHVE1C1CUSPPDS3800NHVE1C1CGENERALELECTRICDS3860DMPKNSFPDS3860DMPKGeneralElectricDS3815PAAA1D1ACircuitBoardUSEDGENERALELECTRICDS215SDCCG3AZZ0​1BUSPPDS215SDCCG3AZZ0GeneralElectricDS3800NEPA1D1CPCBoardNEWGeneralElectricDS3800NGRA1L1DCircuitBoardNEWGENERALELECTRICDS3800HLNC1A1ANSPPDS3800HLNC1A1AGeneralElectricDS3800NDID1M1DDriveInterfaceUSEDGeneralElectricDS3800DMPK1E1DPCBoredUSEDGENERALELECTRICDS3800HSCD1GUSPPDS3800HSCD1GGENERALELECTRICDS3800HSQD1E1BUSPPDS3800HSQD1E1BGENERALELECTRICDS3800HSQD1G1CUSPPDS3800HSQD1G1CGENERALELECTRICDS3800HSQD1G1DUSPPDS3800HSQD1G1DGENERALELECTRICDS3800HSQD1J1GUSPPDS3800HSQD1J1GGENERALELECTRICDS3820MAUDUSPPDS3820MAUDGENERALELECTRICDC2000SCRBRIDGEDS200SHVIG1A*NEW*GENERALELECTRICDC2000SCRBRIDGEDS200SHVIG1A*NEW*GENERALELECTRICDS3800NEPA1C1AUSPPDS3800NEPA1C1AGENERALELECTRICDS3800NEPA1C1BUSPPDS3800NEPA1C1BGENERALELECTRICDS3800NEPA1D1AUSPPDS3800NEPA1D1AGENERALELECTRICDS3800NEPA1D1BUSPPDS3800NEPA1D1BGENERALELECTRICDS3800NEPA1E1DUSPPDS3800NEPA1E1DGENERALELECTRICDS3800NEPA1F1EUSPPDS3800NEPA1F1EGENERALELECTRICDS3800HPTK1BUSPPDS3800HPTK1BGENERALELECTRICDS200PLIBG2ACANSFPDS200PLIBG2ACAGENERALELECTRICDS3800DGRC1B1CUSPPDS3800DGRC1B1CGeneralElectricDS3800NEPA1E1DExcitorBoardGENERALELECTRICDS200GSIAG1ACANSFPDS200GSIAG1ACAGENERALELECTRICDS3800NPSE1B1AUSPPDS3800NPSE1B1AGENERALELECTRICDS3800NPSE1B1BUSPPDS3800NPSE1B1BGENERALELECTRICDS3800NPSE1D1FUSPPDS3800NPSE1D1FGENERALELECTRICDS3800NPSE1E1GUSPPDS3800NPSE1E1GGENERALELECTRICDS3800NPSF1C1BUSPPDS3800NPSF1C1BGENERALELECTRICDS800NPSF1D1DUSPPDS800NPSF1D1DGENERALELECTRICDS3800NPSE1C1CUSPPDS3800NPSE1C1CGENERALELECTRICDS3800HPBCUSPPDS3800HPBCGeneralElectricDS3800NFCD1L1EFiringBoardUSEDGENERALELECTRICDS3800HLNC1A1AUSPPDS3800HLNC1A1AGeneralElectricDS3800NEPA1E1DExcitorBoardUSEDGENERALELECTRICDS3800HSCG1D1EUSPPDS3800HSCG1D1EGENERALELECTRICDS3800NFIBUSPPDS3800NFIBGeneralElectricDS3827ASBB01CellStackUSEDGENERALELECTRICDS3800NFCD1K1CUSPPDS3800NFCD1K1CGENERALELECTRICDS3800NFCD1K1DUSPPDS3800NFCD1K1DGENERALELECTRICDS3800NFCD1K1EUSPPDS3800NFCD1K1EGENERALELECTRICDS3800NFCD1L1EUSPPDS3800NFCD1L1EGENERALELECTRICDS3800NFCD1Q1HUSPPDS3800NFCD1Q1HGENERALELECTRICDS3800NFCD1S1JUSPPDS3800NFCD1S1JGENERALELECTRICDS3800NFCD1S1KUSPPDS3800NFCD1S1KGENERALELECTRICDS3800NFCD1S1LUSPPDS3800NFCD1S1LG
