IC646NMD000控制器IC646NMD000控制器可编程控制器PLC运行时可能会出现死机的情况，这给工业生产造成不可预估的损失，因此，首先要了解PLC死机的原因，针对原因进行排查，软件或硬件错误都有可能导致PLC死机，下面分别进行介绍：1、硬件方面（1）I／O窜电，PLC自动侦测到I／O错误，进入STOP模式。（2）I／O损坏，程序运行到需要该I／O的反馈信号，不能向下执行指令。（3）扩展模块(功能型，如A／D)线路干扰或开路等。（4）电源部分有干扰或故障。（5）PLC的连接模块及地址分配模块出故障。（6）电缆引起的故障。2、软件方面（1）触发了死循环。（2）程序改写了系统参数区的内容，却没有初始化部分。（3）保护程序启动：硬件保护、限制使用时间(针对货款收回)（4）数据溢出，步长过大、看门狗(可修改DOG时间)动作。INDUSTRIALELECTRONICDEVICESNDT-17TUSPPNDT17TASEABROWNBOVERIYT204001-KAUSPPYT204001KAALLENBRADLEY1333-EACUSPP1333EACTEXASINSTRUMENTSPLC560-2126RUSPP5602126RTEXASINSTRUMENTSPLCP05-6201NSFPP056201ASEABROWNBOVERI57288001NSFP57288001ASEABROWNBOVERI3BSE030230R1USPP3BSE030230R1TEXASINSTRUMENTS500-2108*NEWNOBOX*COMPUMOTORA/AX-106-178-SUSPPAAX106178STEXASINSTRUMENTSPLC505-ATM-0440NSPP505ATM0440575-2104TexasInstrumentsSiemensPLC5752104N22ASEABROWNBOVERI086363-001NSFP086363001PanasonicACServoDriverMDDA153A1A1.5kWTEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C1102FujiHensokukiCOGeardMotorMT-9-5.4-002LAPanasonicACServoMotorMQMA022P2BFISCHER&PORTER53MC5412A25BAC​2DXXXXUSPP53MC5412A25BAC​2DRELIANCEELECTRIC45C-601USPP45C601ASEABROWNBOVERI68789010PFNFP68789010PACDCREV-804B-2448-​9001USPPREV804B2448900​1TEXASINSTRUMENTSPLC100-3101NSFP1003101DANFOSS175L3203NSPP175L3203ASEABROWNBOVERIEH450C-32VDC-TNSPPEH450C32VDCTPanasonicMinasACservodriveMSD011A1XXPanasonicServoMotorM***022P1F200WFreeShipTEXASINSTRUMENTSPLCPFS-3607USPPPFS3607TEXASINSTRUMENTSPLC505-7354NSPP5057354***ARTEKT-BOXUSPPTBOXTEXASINSTRUMENTSPROGRAMMABLECONTROLLERTYPE305!ORMECSACS19E/101BUSPPSACS19E101BTEXASINSTRUMENTSPLC505-2590USPP5052590USEDPerceptron96KDSPFrameGrabber495-0191RevNTEXASINSTRUMENTSPLC560-2126BNSFP5602126BTEXASINSTRUMENTSPLC560-2130NSPP5602130USEDPerceptron390-0049Enna17Monitor0520776002KEYENCECORPPI-C92NSFPPIC92PanasonicACServoDriverMSDA043A1AFreeShipASEABROWNBOVERI1923RA00140000​0STDUSPP1923RA00140000​0SSAJF//PANASONICADKF5085AAACSERVODRIVERUNITUSEDTEXASINSTRUMENTSPLC505-4516USPP5054516ASEABROWNBOVERIL***63600USPPL***63600TEXASINSTRUMENTSPLC55CI840390068NSPP55CI840390068TEXASINSTRUMENTSPLC7MT-700NSPP7MT700TEXASINSTRUMENTSPLCVPU210-3104USPPVPU2103104FANUCA20B-2001-0060USPPA20B20010060TEXASINSTRUMENTSPLC505-2556USPP5052556ASEABROWNBOVERI3AFE61001395USPP3AFE61001395ASEABROWNBOVERIHIEE300025R2NSFPHIEE300025R2TRON630264USPP630264TEXASINSTRUMENTSPLC2600555USPP2600555PanasonicMSD083A1XKACServoDriverPanasonicACServoDriverMDDDT3530003FreeShip(AJ01)MSDA015D1APANASONICACSERVODRIVERUSEDWORKINGPILZ301060NSFP301060ALLENBRADLEY1336-C010-EADUSPP1336C010EADALLENBRADLEY1326-CCUT060NSFP1326CCUT060TEXASINSTRUMENTSPLC505-4232NSPP5054232SECOSE2135USPPSE2135NEWTEXASINSTRUMENTSI/OCHANNELRECORDER500-2101ASEABROWNBOVERI289B456A13NSFP289B456A13DANFOSS175L3203NSPP175L3203TexasInstruments5TI-1029-1ACDCREV-804B-2448-​9001USPPREV804B2448900​1TEXASINSTRUMENTSPLC505-7012USPP5057012ASEABROWNBOVERIYPQ-102FUSPPYPQ102FPANASONICMSDA023A1ASERVODRIVEAC200-230VACCONTROLTECHNIQUESDXE-430USPPDXE430TEXASINSTRUMENTSPLCPFS-3606-AUSPPPFS3606ATexasInstruments5TI-3201TISiemens500-21515002151PowerSupply2151APLC,PictureprovideuponrequestASEABROWNBOVERI3HAB2220-1USPP3HAB22201FOXBORO202S-04-XXXXUSPP202S04XXXXASEABROWNBOVERIYB560103-BENSPPYB560103BE)
