1738-IB8M12输出模块1738-IB8M12输出模块可编程控制器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。OMRONAMD-SL1AC100/1​10USPPAMDSL1AC100110ASEABROWNBOVERI3ASD573001A1USPP3ASD573001A1NewinBox530T-1112Siemens/TexasInstrumentsTIPLCProcessor530T1112N787TEXASINSTRUMENTSPLC2490683-U13USPP2490683U13TEXASINSTRUMENTSPLC505-CP1434TFNSFP505CP1434TFASEABROWNBOVERI3BSE018283R1NSFP3BSE018283R1ALLENBRADLEY20AD027F0AYNAN​C0USPP20AD027F0AYNAN​C0TEXASINSTRUMENTSPLC430-CPUNSPP430CPUNEWPERCEPTRON495-0191FRAMEGRABBERPROCESSOR500-0192REVB96KDSPSIEMENSSIMATICTI505PLCWESTINGHOUSEA202K3CAUSPPA202K3CAASEABROWNBOVERIL***63600USPPL***63600ASEABROWNBOVERITWK-G033055NSPPTWKG033055ASEABROWNBOVERIOES400J3NSFPOES400J3ALLENBRADLEY284D-FHD6P0D-2​5-CR-3-DB1-SB-​OCNSFP284DFHD6P0D25C​RASIEMENS6ES5-312-5AA31USPP6ES53125AA31(AG01)PANASONICM***A042A1BACSERVOMOTORWORKINGTISiemens500-50545005054RedundantTiwayPeerlinkPLCTEXASINSTRUMENTSPLC500-5606NSPP5005606TEXASINSTRUMENTSPLC500-9912USPP5009912SIEMENSTIVMEPLC575-2102ALLENBRADLEY810-A10CNSFP810A10CHONEYWELLR7510A-1005USPPR7510A1005SIEMENS1FT6081-8AF71-​4TB0NSPP1FT60818AF714T​B0ASEABROWNBOVERIYB161102-BUNSPPYB161102BUASEABROWNBOVERIHIEE300024R4NSFPHIEE300024R4PanasonicMFA075LD5NSJACServoMotor750WPanasonicACServoMotorMHMD042P1UFreeShipReturns:NotacceptedASEABROWNBOVERIACH550-BD-180A​-4NSFPACH550BD180A4LAMARCHEA12B-20-48VUSPPA12B2048VSANYODENKIPU0B015-EML1P0​0USPPPU0B015EML1P00GEFANUCIC600BF945USPPIC600BF945ASEABROWNBOVERIEH550C-1USPPEH550C1SANYODENKIP80B22350HBV27USPPP80B22350HBV27TEXASINSTRUMENTSPLC5TI-3101USPP5TI3101ARO93970309USPP93970309SIEMENS6SE3-216-8CB40NSFP6SE32168CB40SEWEURODRIVEMDV60A0015-5A3​-4-00USPPMDV60A00155A34​00TexasInstrumentPM550-100TEXASINSTRUMENTSPLC530-1102NSFP5301102MEMOTEC30033107-000USPP30033107000TOHNICHILC2000USPPLC2000NEXENGROUP912743NSFP912743TexasInstrumentsTI140Controller140-1111TexasInstruments505-6870TEXASINSTRUMENTSPLC500-5040USPP5005040PANASONICACSERVODRIVERMSDA043A1A200/230VH1.8AUSEDSANYODENKIRS1L03AZ082USPPRS1L03AZ082TEXASINSTRUMENTSPLC500-2153USPP5002153SIEMENSTI575-2102VMEPLCPanasonic2.5kWACServoDriverMDDA253A1ATEXASINSTRUMENTS500-5019WORDOUTPUTMODULENEW5005019PanasonicACServoMotorM***A012S1AFreeShipRELIANCEELECTRIC0-51831-5NSFP0518315TEXASINSTRUMENTSPLC2497435USPP2497435TEXASINSTRUMENTSPLC535-1212USPP5351212WEINIG1LA5131-2FB90-​ZX51USPP1LA51312FB90ZX​51(AG01)PANASONICM***021ABFACSERVOMOTORWORKINGTEXASINSTRUMENTSPLC575-4916NSFP5754916ASEABROWNBOVERIDSRF-171USPPDSRF171SIEMENSTI6ES5453-4UA12PLCNEWASEABROWNBOVERI57360001-ELUSPP57360001ELORMECSACS19E/101BUSPPSACS19E101BTexasInstruments500-2109Panasonic/NaisServoMotorM***D082P1UNIB!ASEABROWNBOVERIYB161101-GKUSPPYB161101GKFISHERROSEMOUNT895CNSPP895CSQUAREDATV-58NU90N4KUUSPPATV58NU90N4KUPERCEPTRONFRAMEGRABBER4950191PERCEPTRON9110017USPP9110017TEXASINSTRUMENTSPLC500-5884USPP5005884)
