Hello all, Yesterday I have noticed that the EXT FLT led is litting on the PLC 400. When I went diagnostic module information it says this message: 1. Module problem or maintenance necessary 2. Module OK I sent to you in attachment printscreen just to be more clear. The fault that I receive is for Temposonics (for measurement of trans movement) and they are working just fine. So in one case it says that the module has problem, and in the other hand it says that the module is OK. I don't understand. When I went ONLINE diagnostic module, it says that there is no problem. Please can you advise me what to do? Because the customer doesn't like red leds:) Thanks in advance, AttachmentModule problem.zip (614 Downloads) |

Hello, It is a really strange thing what is happening to the PLC. I had EXTF led on all the time. Few days ago I saw the message: "Module problem or maintenance necessary". Yesterday I put the PLC in STOP mode and RUN again, and after that I didn't have this message again, but I had "I/O access error, writing" (in attachment file Diagnose 2807_Morning). After couple of hours working I put the PLC in STOP mode and RUN again, and than again I had the message "Module problem or maintenance necessary" and nothing from the previous message "I/O access error, writing" (in attachment file Diagnose 2807_Evening). Otherwise everything works without problem. AttachmentDiagnose2807.zip (516 Downloads) |

Hi and thanks for your answer... I did download complete project (SW and HW) and the results were the same. Than I did memory reset, download again the SW and the results were the same, I still have the problem...Even I deleted those three modules from the HW and created a new ones, and now the error shows that the new ones are the problem. I don't know what to do, please help... |
