1734-RTB3模块1734-RTB3模块1734-RTB3模块PLC的容量包括I／O点数和用户存储容量两个方面。(一)I／O点数的选择PLC平均的I／O点的价格还比较高，因此应该合理选用PLC的I／O点的数量，在满足控制要求的前提下力争使用的I／O点***少，但必须留有一定的裕量。通常I／O点数是根据被控对象的输入、输出信号的实际需要，再加上10％~15％的裕量来确定。(二)存储容量的选择用户程序所需的存储容量大小不仅与PLC系统的功能有关，而且还与功能实现的方法、程序编写水平有关。一个有经验的程序员和一个初学者，在完成同一复杂功能时，其程序量可能相差25％之多，所以对于初学者应该在存储容量估算时多留裕量。PLC的I／O点数的多少，在很大程序上反映了PLC系统的功能要求，因此可在I／O点数确定的基础上，按下式估算存储容量后，再加20％~30％的裕量。存储容量（字节）＝开关量I／O点数×10＋模拟量I／O通道数×100另外，在存储容量选择的同时，注意对存储器的类型的选择。ASEABROWNBOVERI57350001-CN/2USPP57350001CN2INDRAMATRECO-G06-01-FWUSPPRECOG0601FWPanasonicACServoMotorM***082H4VFreeShipReturns:NotacceptedNewinBox555-1105TexasInstrumentsSiemensTIPLC5551105N14TEXASINSTRUMENTSPLC505-4616NSPP5054616PanasonicM***042A2UEACServoMotorPanasonicMinasACservodriveMSD011A1XXPANASONICACSERVOMOTORMDM082Q2VASEABROWNBOVERIQIFA502USPPQIFA502TEXASINSTRUMENTS5TI-5339INTERFACEMODULE5TI5339PHOENIXCONTACTIBS-PLC5-DSC/I​-TNSFPIBSPLC5DSCITPanasonicACServoMotorMFA092LB2NR920W*NEW*RUCKHMOTORET80M2-FHCTUSPPET80M2FHCTGENERALELECTRICDS3800HLOA1E1CUSPPDS3800HLOA1E1CASEABROWNBOVERIACS800-U1-0011​-5USPPACS800U100115TEXASINSTRUMENTS2601011*USED*M***A042A1GPanasonicACServoMotorFreeShipWINDSORMPMSI3/1S3USPPMPMSI31S3ASEABROWNBOVERI067458-005USPP067458005TEXASINSTRUMENTSPLC505-4232AUSPP5054232AFOXBORO760CSA-2A-1NSFP760CSA2A1TEXASINSTRUMENTSPLC500-2108USPP5002108TEXASINSTRUMENTSPLC7MT-1300USPP7MT1300PanasonicM***D042PJTACServoMotor400WTEXASINSTRUMENTS5TI-1034-2SEQUENCERMODULE***XLNT***MEASUREX05353500NSPP05353500GEFANUCIC600BF814NSPPIC600BF814TEXASINSTRUMENTSPLCU-01PMUSPPU01PMGEFANUCTGT-S000-1-1-A​AUSPPTGTS00011AAREXROTH0-608-750-103NSFP0608750103ASEABROWNBOVERI3HAA2207-002USPP3HAA2207002ARO93970838USPP93970838ANDOVERCONTROLSNET-MASTERUSPPNETMASTERMOOGG415-625USPPG415625ASEABROWNBOVERIACS501-007-4-0​0P5USPPACS501007400P5LENZE9953212FNFP9953212ASEABROWNBOVERIAPTBE-03USPPAPTBE03MITSUBISHIMP-SOP500USPPMPSOP500PanasonicACServoMotorM***082A4BFreeShipALLENBRADLEY2711-K6C1L1USPP2711K6C1L1TexasInstruments5TI-2000TEXASINSTRUMENTSTI500-5038NETWORKINTERFACEMODULESIEMENS6ES5-155-3UA21USPP6ES51553UA21TEXASINSTRUMENTS500-5005INPUTMODULELOT5005005SIEMENS6ES5-324-3UR11USPP6ES53243UR11SANYODENKIPU0A015-EM61P0​0USPPPU0A015EM61P00PANASONICACSERVODRIVERADKA100GVTAAACNCPanasonicM***041A1EACServoMotorFreeShipPanasonicServoMotorM***011P1BFreeShipSiemensTICTi575-461616Point110VACOutputPLCTexasInstruments5754616MODICON140-CPU-113-02NSPP140CPU11302HITACHILINK-SHNSPPLINKSHMEASUREX08596900USPP08596900PERCEPTRON916-4079DIGITALCONTOURLASERSENSORREVCC0400-X0000-Y0​126-Z0287PANASONICACSERVODRIVEMDDDT5540L011.5KWTEXASINSTRUMENTSPLC500-5031USPP5005031BALDORMTE-4070-BLBCENSFPMTE4070BLBCEALLENBRADLEY709-EOAUSPP709EOAPanasonicMHDA153A1AACServoDrive1.5kW(freeshipping)ASEABROWNBOVERI(ABB)DSDP160ASEABROWNBOVERI3HAB2220-1USPP3HAB22201ALLENBRADLEY1771-DENSFP1771DE)
