1794-IA16模块1794-IA16模块1794-IA16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。TEXASINSTRUMENTSPLC505-4132NSPP5054132ASEABROWNBOVERIDSSB-110USPPDSSB110COMPUMOTORPK-130USPPPK130TEXASINSTRUMENTSPLC560-2127BUSPP5602127BPerceptron495-0092PCBoardVMEgrapherVGAGraphicsHONEYWELL51309148-175NSPP51309148175TexasInstruments5TI-1034-1NEWTEXASINSTRUMENTS500-5056DIGITALOUTPUTMODULE5005056TEXASINSTRUMENTS520-1101USPP5201101TexasInstrumentsiManVMEInterfaceII01-31073-104ABoard*60DAYSWARRANTY!*PanasonicACServoDriverMUDS083A1MFreeShipASEABROWNBOVERI57770163NSPP57770163ASEABROWNBOVERI1923RA00140000​0STDUSPP1923RA00140000​0STELEMECANIQUELD5LC130BDNSFPLD5LC130BDTEXASINSTRUMENTSPLC505-4232AUSPP5054232A545-1101TexasInstrumentsSimaticPLCTI545TI5451101N300ALLENBRADLEY150-A35NB-NANSFP150A35NBNAFANUCA20B-2001-0060USPPA20B20010060TEXASINSTRUMENTSPLC425DC-CPUUSPP425D***UTEXASINSTRUMENTSPLC505-5516USPP5055516TEXASINSTRUMENTSPLC2238675-0002USPP22386750002ASEABROWNBOVERI57771682USPP57771682PanasonicMSD023A1XXVACServoDriverFOXBORO280H-SBBA-TSA-​GUSPP280HSBBATSAGPanasonicACServoMotorMHMD082P1C750WFreeShipTEXASINSTRUMENTSPLC2493295-0002USPP24932950002TEXASINSTRUMENTSPLCPM550-5040NSPPPM5505040TORKT930LNSFPT930LASEABROWNBOVERI086370-001NSFP086370001TEXASINSTRUMENTSPLC505-4432USPP5054432TEXASINSTRUMENTSPLC5TI-3100USPP5TI3100TEXASINSTRUMENTSPLC500-5027NSPP5005027PanasonicACServoDriveMCDCT3312B12PanasonicDV451S075ACServoDriveASEABROWNBOVERIYTE-102CUSPPYTE102CTISiemensCTi500-2151-A5002151PowerSupply2151APLCBARBERCOLMANMP-9910USPPMP9910PANASONICNACHIACSERVOMOTORMFMMFM552Q3V5.5KWTEXASINSTRUMENTSPLCPM550-5040USPPPM5505040NEWPANASONICServoMotorMQMA022A1ACNC/ROUTERASEABROWNBOVERI3HAB5957-1NSPP3HAB59571ASEABROWNBOVERILC820TL-R0639USPPLC820TLR0639SIEMENS6SE3290-0DC87-​0FA4USPP6SE32900DC870F​A4SICKOPTICELECTRONICODC100-P120USPPODC100P120ASEABROWNBOVERID***B-127USPPD***B127PanasonicACServoMotorM***A152P1GFreeShipASEABROWNBOVERIYT213001-ABUSPPYT213001ABASEABROWNBOVERIDS-112USPPDS112PanasonicACServoDriverMDDA303A1AFreeShipNewinBox505-7028TexasInstruments/Si​emens5057028N741TEXASINSTRUMENTSPLC2360013-0001USPP23600130001PanasonicMDD153A1VVACServoDriverTexasInstruments2461553-0001ALLENBRADLEY1771-E2CNSPP1771E2CTexasInstruments500-5030PanasonicACServoMotorM***3AZA2AXFreeShipFISCHER&PORTER686B608U01NSPP686B608U01GETTYSN360-33809MUSPPN36033809MTEXASINSTRUMENTSPLC500-5056USPP5005056#TEXASINSTRUMENTS505ALLENBRADLEY512-BJB-1-5R-6​P-24RNSFP512BJB15R6P24RPanasonicACServoMDDDT55401.5KWDriverASEABROWNBOVERIYT212001-AEUSPPYT212001AE)
