IC600CR620控制器IC600CR620控制器IC600CR620控制器日常维护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。ASEABROWNBOVERIYB560103-ANUSPPYB560103ANTEXASINSTRUMENTSPLC505-5041NSFP5055041OKUMABL-MC100E-20TBUSPPBLMC100E20TBTEXASINSTRUMENTS2461449**SIEMENSTI505-4332PLCNEWExpeditedshippingailableALLENBRADLEY512-BJB-1-5R-6​P-24RNSFP512BJB15R6P24RPanasonicACSERVOMOTORM***A082A1GUSEDANDGOODINCONDITIONASEABROWNBOVERI3BSE006065SR1USPP3BSE006065SR1ASEABROWNBOVERIOETL-NF800ASWNSFPOETLNF800ASWALLENBRADLEY1336-B015-EDE-​L3USPP1336B015EDEL3TEXASINSTRUMENTSPLCVPU210-3104USPPVPU2103104TEXASINSTRUMENTSPLC7MT-300NSFP7MT300TEXASINSTRUMENTSPLC55CI840390068NSPP55CI840390068GEFANUCIC650AEM000USPPIC650AEM000TexasInstruments500SystemPLCSeriesRack11ModulesASEABROWNBOVERI3DDE-300-400USPP3DDE300400TEXASINSTRUMENTSPLC565-1101USPP5651101PanasonicLenze***MA40GBK4W1501229/1***GA10BServoMotor3Phase220V50HzPACIFICSCIENTIFICSRF55704483848​2BCNSFPSRF55704483848​2BPanasonicACServoDriverMSDA103A1AFreeShipTEXASINSTRUMENTSPLC530-1108USPP5301108BYSTRONIC702109USPP702109TEXASINSTRUMENTSPLC500-5037AUSPP5005037AFANUCA06B-6057-H001NSPPA06B6057H001GEFANUC44A398714-G02USPP44A398714G02SIEMENSTIPLCDRIVEINTERFACEMODULE6SE31900XX878B​F0PanasonicACServoDriverMSDA043A1ANewinBoxFreeShip(AG01)PANASONICM***021ABFACSERVOMOTORWORKINGPanasonicACServoMotorM***152A2D200V9.4AASEABROWNBOVERI57772280USPP57772280TEXASINSTRUMENTSPLC560-2122USPP5602122PANASONICMSDA5A3A1AACSERVODRIVERNEWFANUCA20B-1001-0551USPPA20B10010551TexasInstruments(Siemens)Mdl:5TI-1082-2Sequencer505-6850ATexasInstrumentsSiemensSimaticTI505-6850-AR100TEXASINSTRUMENTSPLC305-04BUSPP30504BSEIKICOLTDINO-11-10-07-0​4-01BUSPPI***110070401BPanasonicMGMA092A1GACSERVOMOTORFreeShipTexasInstrumentVPU200-3102GETTYSM313A-B00-102USPPM313AB00102BURGMASTER0242109-01ANSFP024210901AALLENBRADLEY1494V-DS600USPP1494VDS600MITSUBISHISP031J027NSFPSP031J027ALLENBRADLEY634978-9004USPP6349789004PanasonicACServoAmplifierMUDB042AADnewNewinBox530T-1112Siemens/TexasInstrumentsTIPLCProcessor530T1112N787TISiemensCTi500-2151-A5002151PowerSupply2151APLCPanasonicACServoMotorM***D042S1SFreeShipTEXASINSTRUMENTSPLC505-4317NSFP5054317ASEABROWNBOVERIDSSR-110USPPDSSR110(AS01)MSDA083D1APANASONICACSERVODRIVEUSEDWORKINGASEABROWNBOVERIYB560103-AMUSPPYB560103AMBAYSIDERA115-010USPPRA115010LEYBOLDCM31USPPCM31PanasonicACServoDriverMDDHT5540FreeShipTEXASINSTRUMENTSPLC555-1102USPP5551102ASEABROWNBOVERI3ADT306200R1NSPP3ADT306200R1PARKERLA470617U001FNFPLA470617U001RUCKHMOTORET80M2-FHCTUSPPET80M2FHCTTEXASINSTRUMENTSPLC505-4308NSFP5054308TEXASINSTRUMENTSPLC505-7016USPP5057016ASEABROWNBOVERINAA214154512NSPPNAA214154512)
