1794-IB16XT输出模块1794-IB16XT输出模块1794-IB16XT输出模块日常维护PLC的日常维护和***比较简单,主要是更换丝和锂电池,基本没有其它易损元器件。由于存放用户程序的随机存储器(RAM)、计数器和具有保持功能的辅助继电器等均用锂电池保护,锂电池的寿命大约为5年,当锂电池的电压逐渐降低到一定程度时,PLC基本单元上电池电压跌落到指示灯亮,提示用户注意有锂电池所支持的程序还可保留一周左右,必须更换电池,这是日常维护的主要内容。调换锂电池的步骤为:■在拆装前,应先让PLC通电15秒以上(这样可使作为存储器备用电源的电容器充电,在锂电池断开后,该电容可对PLC做短暂供电,以保护RAM中的信息不丢失);■断开PLC的交流电源;■打开基本单元的电池盖板;■取下旧电池,装上新电池;■盖上电池盖板。注意更换电池时间要尽量短,一般不允许超过3分钟。如果时间过长,RAM中的程序将消失。此外,应注意更换丝时要采用型号的产品。I/O模块的更换若需替换一个模块,用户应确认被安装的模块是同类型。有些I/O系统允许带电更换模块,而有些则需切断电源。若替换后可解决问题,但在一相对较短时间后又发生故障,那么用户应检查能产生电压的***负载,也许需要从外部其电流尖峰。如果丝在更换后易被烧断,则有可能是模块的输出电流超限,或输出设备被短路。PLC的故障诊断是一个十分重要的问题,是保证PLC控制系统正常、可靠运行的关键。本文对常用的故障诊断方法进行了探讨。在实际工作过程中,应充分考虑到对PLC的各种不利因素,定期进行检查和日常维护,以保证PLC控制系统安全、可靠地运行。TEXASINSTRUMENTSPLC505-6851BUSPP5056851BGUTICOR100G-1M1R0USPP100G1M1R0GETTYS110-0108USPP1100108PanasonicACSERVODRIVERMADDT1207003200WfreeshipPanasonicMSD083A2XXACSERVODRIVERADEPTTECH10300-15520NSFP1030015520NEWPERCEPTRON495-0191FRAMEGRABBERPROCESSOR500-0192REVB96KDSPTISiemens500-50545005054RedundantTiwayPeerlinkPLCASEABROWNBOVERI1SDA054335R1USPP1SDA054335R1OMRONAMD-SL1AC100/110USPPAMDSL1AC100110TEXASINSTRUMENTS5TI-1034-2USEDSEQUENCERMODULE5TI10342ASEABROWNBOVERIDSSB-110USPPDSSB110CONVERGENTENERGY409600PNSPP409600PSIEMENS6ES5-927-3KA12USPP6ES59273KA12ASEABROWNBOVERI57310001-CC/4USPP57310001CTEXASINSTRUMENTSPLC500-5018USPP5005018TEXASINSTRUMENTSPLC505-2571NSPP5052571PERCEPTRON911-0007TEXASINSTRUMENTS520C-1102**TexasInstruments500-5037FOXBORO138SP-4-EUSPP138SP4ETEXASINSTRUMENTSPLCVPU500-3104USPPVPU5003104XYCOMXVME-661NSFPXVME661EMHART600-560-3NSFP6005603TEXASINSTRUMENTSPLC575-4616NSFP5754616TEXASINSTRUMENTSPLC500-5021NSPP5005021ALLENBRADLEY160-AA18PS1-AF-DS-PICNSPP160AA18PS1AFDSPITEXASINSTRUMENTS500-5062**RELIANCEELECTRIC801429-5SBUSPP8014295SBTEXASINSTRUMENTSPLC505-4916AUSPP5054916ATEXASINSTRUMENTSPLC5TI-1021-1USPP5TI10211STI42619-0200USPP426190200PanasonicACServoMotorM***A402D1AFreeShipTexasInstrumentsRTU-AOT-1AnalogOutputBoard520-066ASEABROWNBOVERIDSQC236AUSPPDSQC236AFORCECOMPUTERSSYS68K/RR-3USPPSYS68KRR3ExpeditedshippingailableASEABROWNBOVERIGNT2009421R0001NSPPGNT2009421R0001TEXASINSTRUMENTSPLC505-4317NSFP5054317GOSSWH715214-HNSPPWH715214HGENERALELECTRICCR193C110L007080UNSFPCR193C110L007080ITESIEMENSCED63B015LNSFPCED63B015LALLENBRADLEY1775-AD1USPP1775AD1SIEMENSTI505-4316APLCNEWFISHERROSEMOUNT895CNSPP895CTEXASINSTRUMENTSPLC2587716-8001NSFP25877168001ASEABROWNBOVERI3ADT220026R0001USPP3ADT220026R0001TISiemens500-58405005840ControllerAdapterBaseGrnPLC(AB02)DV8C150SDDBPANASONICSERVODRIVERUSEDWORKINGTEXASINSTRUMENTSPLC505-6860NSFP5056860TEXASINSTRUMENTSPLC500-7111USPP5007111ASEABROWNBOVERIYB161102-BKUSPPYB161102BKASEABROWNBOVERIDSDX-110NSPPDSDX110PanasonicACServoAmplifierMUDB042AADnewASEABROWNBOVERIYTE-102CUSPPYTE102CTEXASINSTRUMENTSPLC530C-1108USPP530C1108TEXASINSTRUMENTSPLC530-6202NSFP5306202PanasonicACServoDriverMDD103A1VVFreeShipPERCEPTRONCAMERATRICAMSURFACESENSOR912-0014FOXBOROD3005PK-BBNSPPD3005PKBBTEXASINSTRUMENTS500-5047-A**ASEABROWNBOVERIP1040QNSFPP1040QPERCEPTRON912-0008)
