1775-S4A输出模块1775-S4A输出模块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。505-6660TexasInstrumentsSiemensTI5056660SIEMENS6SE9212-1CA40NSFP6SE92121CA40PHOENIXCONTACTIBS-PLC5-DSC/I​-TNSFPIBSPLC5DSCITTexasInstruments5TI-3000ExpeditedshippingailablePERCEPTRON912-0010USPP9120010ASEABROWNBOVERI1913JA00210000​0USPP1913JA00210000​0IMPCO14339ANSFP14339AASEABROWNBOVERI58114791USPP58114791ALLENBRADLEY1333-EACUSPP1333EACNSKEE1410A05-24.1USPPEE1410A05241TEXASINSTRUMENTSPLC500-5052USPP5005052METRAINSTRUMENTS611-0011-000USPP6110011000TEXASINSTRUMENTSPLC545-1106USPP5451106TEXASINSTRUMENTSPLC7MT-1504NSPP7MT1504PanasonicMQDB011AAD03ACServoDriver0190-19214workingPANASONICSERVOMOTORM***022Q8VGEFANUCIC646NMP000NSFPIC646NMP000(AB01)PANASONICADKB400BPFADAACSERVODRIVEUNITWORKINGALLENBRADLEY2711-K6C8USPP2711K6C8PanasonicACServoDriverMSD011A0XXTEXASINSTRUMENTSPLC24-901-30-000NSPP2490130000MITSUBISHIMR-J2S-500BUSPPMRJ2S500BTEXASINSTRUMENTSPLC500-2161NSFP5002161TexasInstrumentsTI164(164-1111)PanasonicServoDriveADKA500BPFADHworkingTexasInstruments2493295-0003TEXASINSTRUMENTSPLC505-6516NSPP5056516ASEABROWNBOVERI3HAB6182-1USPP3HAB61821ASEABROWNBOVERIDSQC-236DUSPPDSQC236DFISCHER&PORTER53MC5412A25BAC​XDXFXXUSPP53MC5412A25BAC​XDTAYLORELECTRONICS6215BZ10000AUSPP6215BZ10000AOnePanasonicServoDriverMADDT1207+OneMotorM***D022S1TFreeShipWorldwideNEWPANASONICServoMotorM***A041A1ACNC/ROUTERBURGMASTER0282028-02ANSFP028202802ATexasInstruments330-07MODICONMM-PMAB001NSFPMMPMAB001ACCURAY18383-004USPP18383004APWMCLEAN28-0226-003USPP280226003ASEABROWNBOVERIDSQC-236TUSPPDSQC236TXYCOM3300ACTUSPP3300ACTASEABROWNBOVERIPP07512HSFNFPPP07512HSTEXASINSTRUMENTSPLC505-4432USPP5054432TEXASINSTRUMENTSPLC500-9940NSFP5009940TexasInstrument500-584814ModuleI/Obase5005848A+TEXASINSTRUMENTSPLC505-5190NSFP5055190TEXASINSTRUMENTSPLCMON-4614-***NSFPMON4614***SIEMENS6ES5-923-3UA11NSFP6ES59233UA11ASEABROWNBOVERIMEM86-192KNSPPMEM86192KTEXASINSTRUMENTS505-CP5434-FMSUSPP505CP5434FMSLENZE9953212FNFP9953212HAYSSEN10717A0605USPP10717A0605PanasonicMSD021A1XXACservodriverASEABROWNBOVERIACS601-0011-4-​000B1500801USPPACS60100114000​B2ASEABROWNBOVERIACS401604135USPPACS401604135TexasInstrumentsRTU-8450P1CommunicationBoardASEABROWNBOVERI58116076USPP58116076ASEABROWNBOVERIACS501-020-4-0​0P2USPPACS501020400P2LUCENTTECHNOLOGIESD-CI-B2USPPDCIB2TEXASINSTRUMENTSPLC505-CP2572USPP505CP2572TEXASINSTRUMENTSMODEL500-5053PEERLINKINTERFACEPanasonicACServoMotorMFA100MB5NSA_MFA100MB5NSATEXASINSTRUMENTSPLC55PL8312000328USPP55PL8312000328TexasInstrumentsPM550-102TEXASINSTRUMENTS500-5005INPUTMODULELOT5005005PERCEPTRON911-0010ASEABROWNBOVERIACH501-015-2-0​0P2USPPACH501015200P2TEXASINSTRUMENTSPLC500-5828USPP5005828PANASONICNACHIACSERVOMOTORMFMMFM552Q3V5.5KWALLENBRADLEY1771-OF05NSFP1771OF05ASEABROWNBOVERIACS501-025-4-0​0P5USPPACS501025400P5ASEABROWNBOVERIDSQC266AUSPPDSQC266A)
