1754-BAT***1754-BAT***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。ASEABROWNBOVERIDCS502-B025051​21USPPDCS502B0250512​1FISHERROSEMOUNTDPR-960NSFPDPR960PROFACEGP577R-T1-24​VPNSPPGP577RT124VPBAYNETWORKSCG1001D05USPPCG1001D05PanasonicACServoMotorM***A021A1UFreeShipALLENBRADLEY2755-T4NSFP2755T4PanasonicMUDS5A5A1AACSERVODRIVEMUDS5A5A1A50W200ASEABROWNBOVERIGNT0137111P000​2USPPGNT0137111P000​2SAFTRONICSCIMR-H11G2-E-1​0USPPCIMRH11G2E10PanasonicACServoMotorM***021A1AXw/60daywarrantyExpeditedshippingailableTEXASINSTRUMENTSPLC500-5030USPP5005030TEXASINSTRUMENTSPLCPFS-3606-ANSFPPFS3606ATEXASINSTRUMENTSPLC510NSFP510FLUIDCOMPONENTSLT81A-A1D00000​1CA001240BB075​3C2A201A1A1B1A​10002B1AUSPPLT81AA1ALLENBRADLEY1326AB-B520E-2​1USPP1326ABB520E21PanasonicServoMotorM***011P1BFreeShip(AG01)PANASONICMQMZ022A1FACSERVOMOTORABLEVRKF-15C-200-ZWORKINGASEABROWNBOVERIACS800-U1-0011​-5USPPACS800U100115PanasonicACServoMotorM***022A1BEFreeShipJOSLYNCLARKA10162266ANSFPA10162266APanasonicACServoDriverMUDS083A1MFreeShipRELIANCEELECTRIC1SU44010USPP1SU44010SICKOPTICELECTRONICODC100-P120USPPODC100P120PANASONICACSERVODRIVEADKF50B5AN60W,80WFUJIELECTRICB128C-2ANSFPB128C2AASEABROWNBOVERI283-012USPP283012PanasonicMFA020LE2NSCACServoMotorwith60daywarrantyPanasonicACServoDriverMCDDT3520052750WFreeShipTEXASINSTRUMENTSPLCP05-6201NSFPP056201TexasInstruments500-5035CustomPID/Basic5005035PanasonicACServoDriverMSD021A1X04FreeShipASEABROWNBOVERI05MA21USPP05MA21ASEABROWNBOVERIACH501-015-4-0​0P2USPPACH501015400P2AUTOMATEDLOGICSE6104NSFPSE6104PANASONICACSERVODRIVERADKA100GVTAAACNCTELP-8PanasonicMSD011P1EA03ACServoDriverSetMSD021P1EA03workingTEXASINSTRUMENTS500-5047-A5005047AALLENBRADLEY1336S-BRF50-AA​-EN-L6USPP1336SBRF50AAEN​LAPanasonicLenze***MA40GBK4W1501229/1***GA10BServoMotor3Phase220V50HzPanasonicM***D082PJAACServoMotorASEABROWNBOVERIYB161101-GKUSPPYB161101GKTexasInstrumentsTISiemens16MODULEI/OBASE500-5828APanasonicServoMotorM***022P1F200WFreeShipTEXASINSTRUMENTSPLC100-3103USPP1003103ASEABROWNBOVERIACS401601132NSFPACS401601132ASEABROWNBOVERI57275707NSPP57275707TEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C1102PanasonicACServoDriverMSDA041A1A100-115V400W(J)YASKAWAELECTRICJRMSP-P7011NSFPJRMSPP7011ALLENBRADLEY8000-LBNSFP8000LBTexasInstrumentVPU200-3102TexasInstruments500-5055EECAEG029147614USPP029147614TEXASINSTRUMENTSPLC505-6851USPP5056851ELECTROCRAFT9101-2161USPP91012161ASEABROWNBOVERIAPIOS-02USPPAPIOS02ASEABROWNBOVERI3BSE008546R1USPP3BSE008546R1TEXASINSTRUMENTSPLCPM550-200USPPPM550200ASEABROWNBOVERINF327-4PNSFPNF3274PPERCEPTRON911-0025USPP9110025PanasonicACServoMotorM***A102A1G1kW220VFreeShipSTEARNS108778105007NSFP108778105007PANASONICACSERVODRIVERMDD203A1W200V50/60HZ2.0KW2500P/RHASESICKOPTICELECTRONICCLV-295-0012USPPCLV2950012TEXASINSTRUMENTSPLC2493295-0002USPP24932950002ASEABROWNBOVERI3HAC-17484-2/0​0NSPP3HAC17484200PanasonicACServoMotorMDMS022C2D1SFreeShipASEABROWNBOVERI57310001-BYUSPP57310001BY(AB01)ACSERVODRIVERPANASONICMATSUSHITAELECTRICMSD011A1XX18WORKINGTEXASINSTRUMENTSPLC120-1112NSFP1201112(AB01)ACSERVOMOTORPANASONICMATSUSHITAELECTRICM***Z042B1EWORKING)
