6FX1121-4BM03模块6FX1121-4BM03模块PLC的容量选择PLC的容量包括I／O点数和用户存储容量两个方面。1．I／O点数PLC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I／O点***少，但必须留有一定的备用量。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％的备用量来确定。2．用户存储容量用户存储容量是指PLC用于存储用户程序的存储器容量。需要的用户存储容量的大小由用户程序的长短决定。一般可按下式估算，再按实际需要留适当的余量（20％－30％）来选择。存储容量=开关量I／O点总数X10十模拟量通道数X100绝大部分PLC均能满足上式要求。应当要注意的是：当控制系统较复杂。数据处理量较大时，可能会出现存储容量不够的问题，这时应特殊对待。NIBTEXASINSTRUMENTS305-25NINPUTMODULETexasInstruments500-50017MT-1504TexasInstrumentsTIThermocouple7MT1504G309ASEABROWNBOVERI29089124USPP29089124SIEMENS/TEXASINSTRUMENTS/CT​I505-7354PEERLINK***XLNT***TEXASINSTRUMENTSPLC530C-1104USPP530C1104SIEMENS1HU3104-0AD01-​ZUSPP1HU31040AD01ZTEXASINSTRUMENTSPLCPM550-116USPPPM550116PanasonicDV83020LE201ACServoMotorDriverwith60daywarrantyASEABROWNBOVERI58422177USPP58422177ASEABROWNBOVERI3HAB2242-1USPP3HAB22421ASEABROWNBOVERI264C901A07NSFP264C901A07GRACEINTERNATIONALCORP421421-3NSFP4214213SHARPLMCH5322NTKFNFPLMCH5322NTKALLENBRADLEY8600-2158SUSPP86002158SPanasonicLenze***MA40GBK4W1501229/1***GA10BServoMotor3Phase220V50HzTEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C1102MODICON140-CPU-113-02NSPP140CPU11302PanasonicACServoMotorMFA100LB2BSA#5927ASEABROWNBOVERIYB560103-CB/10USPPYB560103CB10GEFANUCIC3600SBMA1USPPIC3600SBMA1SimaticTI330DirectLogicPLCcompleteWithprogrammerASEABROWNBOVERI57520001-BZUSPP57520001BZTELP-8PanasonicMSD011P1EA03ACServoDriverSetMSD021P1EA03workingPANASONICACSERVOMOTORMUMS041A1F0SSSECSERVOCONTROLLERTEXASINSTRUMENTSPLCPFS-3606-ANSFPPFS3606ATEXASINSTRUMENTSPLC505-5190USPP5055190TEXASINSTRUMENTS500-5035PROGRAMMABLEBASICMODULE5005035NSDV8T22-51NSPPV8T2251TEXASINSTRUMENTSPLC575-2103NSFP5752103ASEABROWNBOVERIDCS502-B025051​21USPPDCS502B0250512​1PanasonicACServoMotorM***Z042B1EFreeShipASEABROWNBOVERISPAD-346-C3NSPPSPAD346C3ASEABROWNBOVERI289B943A30NSFP289B943A30ASEABROWNBOVERI283-012USPP283012DELTATAUDATASYS3A0-602804-108NSPP3A0602804108ASEABROWNBOVERIEHDB520M2P-1LNSFPEHDB520M2P1LTEXASINSTRUMENTSPLC5TI-4000USPP5TI4000FISHERROSEMOUNT3051-CD3A02A1A​E5S5NSFP3051CD3A02A1AE​5SAseaBrownBoveriABBDriveACS501-050-4-0​0P2460VACACS501050400P2TELEMECANIQUETPMXP57102USPPTPMXP57102TEXASINSTRUMENTSTI500-5038NETWORKINTERFACEMODULETEXASINSTRUMENTSPLCPM550-KEYPADUSPPPM550KEYPADASEABROWNBOVERIS4L250EWUSPPS4L250EWTexasInstrumentsPM550-200USEDPerceptron147SerialBoard495-0102-01093097-003TEXASINSTRUMENTSPLC500-5848USPP5005848Perceptron912-0008TricamSurfaceSensorDEMAG502001USPP502001PanasonicACServoDriverMBDDT2210053FreeShipASEABROWNBOVERI3BHB002916R010​1USPP3BHB002916R010​1ASEABROWNBOVERI57520001-CNUSPP57520001CNCUTLERHAMMERS20K11S10NUSPPS20K11S10NTEXASINSTRUMENTSPLC505-7101USPP5057101INDRAMATFWA-CLM1.3-LA1​-03VRS-MSUSPPFW***M13LA103V​RSTexasInstruments2493295-0003KEYENCECORPPI-C92NSFPPIC92TexasInstruments500-5023ASEABROWNBOVERI2668-184-227/2USPP26681842272ASEABROWNBOVERIEH175C-1NSFPEH175C1ASEABROWNBOVERI1923RA00140000​0STDUSPP1923RA00140000​0SLENZEBFK458-25ENSFPBFK45825ETEXASINSTRUMENTSPLC500-5062USPP5005062CTI2572forTexasInstruments/Si​emensTI2572TexasInstrumentsPM550-210PowerSupplyPM550210(UGC)ASEABROWNBOVERIEH250C-YUSPPEH250CYASEABROWNBOVERI3BSE004940R1NSPP3BSE004940R1TEXASINSTRUMENTSPLC500-5030NSPP5005030TEXASINSTRUMENTSPLC505-6516NSPP5056516PanasonicMSD083A1XACServoDriverFreeShipPanasonicMCDDT3520053ACServoDriverFreeShipTEXASINSTRUMENTSSiemensTIPN560-2136)
