IC200MDL141输入模块IC200MDL141输入模块我厂KP8000t热模锻压力机铸造生产线,由5台OMRONC200H型可编程序控制器(PC)控制。下面介绍我们对PC一次CPU停机故障排除方法,以期同行指正。1.故障现象据值班电工反映,系统电源指示灯POWER亮,正常操作外部开关、按按钮时,CPU面板上ERROR报警指示灯亮,外部输出切断,当时刚好上午准备下班。下开机时,从CPU内部冒出一股浓烟,此时,PC交流电压为247V左右。2.故障分析及处理当PC控制出现下列优先级错误时会引起CPU停机:CPUWAIT’G(CPU等待)、MEMORYERR(存储器错误)、NOENDINST(无结束语句)、I/OBUSERR(I/O总线错误)、I/OSETERR(I/O设置错误)、I/OUNITERR(I/O单元错误)、SYSFAILFALS(系统出错)等。用编程器读出出错信息如下:COUWAIT’G、MEMORYERR。拆下该CPU,经查看内部线路,发现CPU内部电源部分一集成件SI-9510A已炸开,显然,CPU不能运行。可能原因是当时电源电压高于OMRON产品给定电压值(240Va.c)7V左右或该集成件本身质量欠佳造成的。更换同型号CPU,ERROR红灯仍亮,系统不能启动,用编程器读出的出错信息依然如故。为了防止意外和查看问题方便,我们将备用的存贮器换上,因其RAM中无用户程序。此时,能引发CPU等待的错误主要有两个方面:特殊I/O单元等待及扩展I/O单元等待。首先,我们查看了扩展单元的各部分,其电源供给正常,发现连接电缆插头松动,插好,试机,PCCPU依然停机,但无存贮器错误显示。由于系统未进行I/O地址登记,为查找原因方便,将扩展机架“离线”操作,直接检查主板特殊单元。存贮器中RAM为空白,只要拆下坏的模板后,CPU就应运行,其RUN指示灯亮(编程器置RUN或MONIT状态)。当拆下主板上OD215模板后,RUN亮,将备用的OD215进行状态设置,替换后也亮。此时,再将原来的存贮器换上,结果编程器上蜂鸣器马上声响,又出现MEMORYERR出错信息,可见存贮器也被烧坏。只能用备用的存贮器,重新输入原始用户程序,分段检查、试车,***后全部重新试车,系统正常,交付使用。直此,笔者认为引起这次停机故障的可能原因是特殊I/O单元OD215损坏,又由于偶然因素如电压偏高,使CPU烧坏及存贮器损坏。3.体会(1)PC控制系统设计时,其电源的稳压设计必须引起重视,以满足当地电压波动范围适合PC规范要求,为此,我们正着手改进原电源线路(2)程序需备份。设计者一般均有程序备份,用户手中也必须有正确的程序清单。(3)平时应当注意何处可以购买到备件,以便及时修复机器。TEXASINSTRUMENTSPLC5TI-5011NSFP5TI5011PanasonicACServoDriverMDDDT55401.5KWFreeShipMITSUBISHIMR-SO203SUSPPMRSO203SALLENBRADLEY150-A24NB-NANSFP150A24NBNAASEABROWNBOVERI57360001-ELUSPP57360001ELTEXASINSTRUMENTSPLC45AF9106000169USPP45AF9106000169OMRONCV1000-CPU01-ENSFPCV1000CPU01ETEXASINSTRUMENTSPLC500-5001NSFP5005001TEXASINSTRUMENTSPLC500-5027NSPP5005027GETTYSM313A-B00-102USPPM313AB00102ASEABROWNBOVERIEH550C-Q1NSPPEH550CQ1HAYSSEN10717A0605USPP10717A0605ASEABROWNBOVERIYT204001-FCUSPPYT204001FCGIDDINGS&LEWIS401-50326-00USPP4015032600PanasonicACServoDriverMSD013A1XXFreeShipASEABROWNBOVERI57120001-FGUSPP57120001FGTEXASINSTRUMENTSPLC505-4916AUSPP5054916ATEXASINSTRUMENTSPLC575-4616NSFP5754616TexasInstruments505-6108(A/B)PERCEPTRON912-0011USPP9120011TEXASINSTRUMENTSPLC945940-0001-ACUSPP9459400001ACPanasonicMatsushitaSERVOMOTORM***A012A1G100W60dayswarrantyTEXASINSTRUMENTSPLC505-6851AUSPP5056851APANASONICMSDA153D1AACSERVODRIVER1.5kwTEXASINSTRUMENTSPLC505-2557USPP5052557TEXASINSTRUMENTSPLC500-5022USPP5005022INDRAMATDDS02.2-W015-BEUSPPDDS022W015BETEXASINSTRUMENTSPLCVPU200-3101USPPVPU2003101ELECTROCRAFTPDM10USPPPDM10TEXASINSTRUMENTSPLC505-CP5434--L2-DPUSPP505CP5434L2DPSIEMENS6DS1332-8BCUSPP6DS13328BCASEABROWNBOVERIACH501-015-2-00P2USPPACH501015200P2INDRAMATMAC090B-0-PD-1-B/110-A-0/I01000USPPMAC090B0PD1B110CTEXASINSTRUMENTSPLC560-2124USPP5602124ExpeditedshippingailableSIEMENSSIMATICTI505PLCTEXASINSTRUMENTSPLC2490005-0001USPP24900050001ASEABROWNBOVERIEH550C-Q1NSPPEH550CQ1ALLENBRADLEY1336-B003-EAD-FA2-L3-S1USPP1336B003EADFA2L3SAJF//PANASONICMSD043A1XXACSERVODRIVEUSEDTITexasInstruments500-588412-SlotRackbase5005884OnePanasonicServoDriverMBDDT2210FreeShipPanasonicACServoMotorM***A102A1DFreeShipMODICON140-CPU-113-03USPP140CPU11303TEXASINSTRUMENTSPLC5TI-1013-1USPP5TI10131TEXASINSTRUMENTSPLC500-5828USPP5005828TEXASINSTRUMENTSPLC5TI-1013USPP5TI1013ASEABROWNBOVERI3BSE030230R1USPP3BSE030230R1TEXASINSTRUMENTSPLC500-5013NSPP5005013ALLENBRADLEY1336S-BRF05-AA-EN4-HA2NSFP1336SBRF05AAEN4HBARDEHWH24A-C06NSPPEHWH24AC06ASEABROWNBOVERIPSTB57060070USPPPSTB57060070ASEABROWNBOVERIYB560103-CB/10USPPYB560103CB10PanasonicNachiACServoMotorMFMA552D5V35.5kWNEWTEXASINSTRUMENTSPLC565-2820USPP5652820TEXASINSTRUMENTSPLC505-5041NSFP5055041ASEABROWNBOVERIS4L250EWUSPPS4L250EWPanasonicACServoMotorM***A082A1AFreeShipTEXASINSTRUMENTSPLC2360013-0001USPP23600130001TexasInstrumentsCUSTOMPIDMODULETEXASINSTRUMENTSPLC2497447USPP2497447PanasonicACServoDriverMDDHT5540FreeShipASEABROWNBOVERIDSDP-150USPPDSDP150WESTINGHOUSE15RBA4-PNMUSPP15RBA4PNMPanasonicMQMZ012A2UACSERVOMOTORNEWSiemensTICTi575-461616Point110VACOutputPLCTexasInstruments5754616PANASONICSERVOMOTORMDM202A1GASEABROWNBOVERIQK-190-0R6501USPPQK1900R6501SPECTRUMCONTROLS1756SC-IF8HNSFP1756SCIF8HTexasInstruments530-1104ALLENBRADLEY1770-SBUSPP1770SBGENERALELECTRICDS3800NPSF1D1EUSPPDS3800NPSF1D1E)
