IC200MDD840模块IC200MDD840模块IC200MDD840模块PLC的编址就是对PLC内部的元件进行编码，以便程序执行时可以地识别每个元件。PLC内部在数据存储区为每一种元件分配一个存储区域，并用字母作为区域标志符，同时表示元件的类型。如：数字量输入写入输入映象寄存器（区标志符为I），数字量输出写入输出映象寄存器（区标志符为Q），模拟量输入写入模拟量输入映象寄存器（区标志符为AI），模拟量输出写入模拟量输出映象寄存器（区标志符为AQ）。除了输入输出外，PLC还有其他元件，V表示变量存储器；M表示内部标志位存储器；***表示特殊标志位存储器；L表示局部存储器；T表示定时器；C表示计数器；HC表示高速计数器；S表示顺序控制存储器；AC表示累加器。掌握各元件的功能和使用方法是编程的基础。下面将介绍元件的编址方式。存储器的单位可以是位（bit）、字节（Byte）、字（Word）、双字（DoubleWord），那么编址方式也可以分为位、字节、字、双字编址。1.位编址位编址的方式为：（区域标志符）字节号�位号，如I0.0；Q0.0；I1.2。2.字节编址字节编址的方式为：（区域标志符）B（字节号），如IB0表示由I0.0～I0.7这8位组成的字节。3.字编址字编址的方式为：（区域标志符）W（起始字节号），且有效字节为起始字节。例如VW0表示由VB0和VB1这2字节组成的字。4.双字编址双字编址的方式为：（区域标志符）D（起始字节号），且有效字节为起始字节。例如VD0表示由VB0到VB3这4字节组成的双字。PanasonicACServoMotorM***D022PJTFreeShipASEABROWNBOVERI3BSE006065SR1USPP3BSE006065SR1ASEABROWNBOVERI3HAB2214-1/1USPP3HAB221411TOHNICHILC2000USPPLC2000TEXASINSTRUMENTSPLC2497284USPP2497284ASEABROWNBOVERIYTE-102AUSPPYTE102ASimaticTI330DirectLogicPLCcompleteWithprogrammerASEABROWNBOVERI3BHT300040R1NSPP3BHT300040R1TexasInstruments520C-1102Series500ControllerPANASONICSERVODRIVERMfDDTA390L013KWALLENBRADLEY2705-EM11J1396​35USPP2705EM11J13963​5TEXASINSTRUMENTSPLC545-1102USPP5451102USEDPerceptron912-0045EMinicamSurfaceSensorBURGMASTER0282028-02ANSFP028202802AASEABROWNBOVERIYB560103-BENSPPYB560103BENEWPANASONICServoMotorM***A102A1CCNC/ROUTERASEABROWNBOVERIDCS401-0610USPPDCS4010610DV80X220MR5PANASONICACSERVODRIVERDV80XINPUT200VOUTPUT2.2KW2500ENCODERTEXASINSTRUMENTSPLC565-1101USPP5651101AMETEKZF2-480-60-UB-​01USPPZF248060UB01ALLENBRADLEYMPL-B430P-MJ22​AANSFPMPLB430PMJ22AATexasInstrument560-2128TEXASINSTRUMENTSPLC7MT-300NSFP7MT300PULSECONTROLBOARDASEABROWNBOVERILSB-6-3-600-LU​M2USPPLSB63600LUM2PANASONICMSDA5A3A1AACSERVODRIVERNEWASEABROWNBOVERIYTE-102BUSPPYTE102BTEXASINSTRUMENTSPLC505-2595USPP5052595ASEABROWNBOVERIYT221001-LSUSPPYT221001LSTEXASINSTRUMENTSPLC505-6108USPP5056108ASEABROWNBOVERI57775840NSFP57775840SQUAREDMAL36450-8041NSFPMAL364508041ASEABROWNBOVERIS6D630W4NSFPS6D630W4PANASONICMSDA023A1ASERVODRIVEAC200-230VACASEABROWNBOVERIACS501-007-4-0​0P5USPPACS501007400P5ALLENBRADLEY1336F-BRF100-A​N-ENUSPP1336FBRF100ANE​NALLENBRADLEY1336-B003-EAD-​FA2-L2USPP1336B003EADFA2​L2ASEABROWNBOVERIYT204001-BNUSPPYT204001BNASEABROWNBOVERIACH501-050-4-0​0P2USPPACH501050400P2SimaticTI330DirectLogicPLCcompleteWithprogrammer505-6840TexasInstruments/Si​emensTI5056840R31REXROTHLTE-45USPPLTE45XYCOM3406-000001000​0000NSFP34060000010000​00TEXASINSTRUMENTSPLC555-1101USPP5551101SIEMENS6ES5-095-8MB02USPP6ES50958MB02SAJF//PANASONICDV80X250MF5ACSERVODRIVERUSEDKEBCOMBIVERT17.F5.B1G-350ANSFP17F5B1G350AALLENBRADLEY1784-PCMK/BUSPP1784PCMKBCTICRYOGENICS8112105NSPP8112105ASEABROWNBOVERIACH501-030-4-0​0P2USPPACH501030400P2TEXASINSTRUMENTS505-7012NSFP5057012ACCUSORT22NSPP22ASEABROWNBOVERI57120001-DPUSPP57120001DPPanasonicACServoMotorMAMR042R1A1NewinBoxFreeShipRELIANCEELECTRICS-12011-1TUSPPS120111TPanasonicServoMSDA041D1A&MotorM***A041C1C400WLNCTexasInstruments8SlotPLCRack405U-20TU-15TU-25NGENERALELECTRIC9L10MAL334USPP9L10MAL334TexasInstrumentsPM550-111ControllerPM550111BAUMANN54R-25000NSFP54R25000FISHERROSEMOUNT8732CT12N0M4USPP8732CT12N0M4ASEABROWNBOVERI1SDA054335R1NSPP1SDA054335R1PanasonicACServoDriveMCDCT3312B12)
