Hi, The INTF led can be on for many reasons. Unless you save(and upload) the diagnostic buffer we can not tell you the reason(s). Have a look at this manual for info about your hardware and LED statuses: https://support.industry.siemens.com/cs/us/en/view/19538001 I hope I could help! |

Hi, No problem. Have a look at this link about diagnosing Profibus networks: https://support.industry.siemens.com/tf/ww/en/posts/19855/ By the way my favorite method is the visual inspection. Most of the cases the issue caused by a broken plug, loose wire, injured cable ... and POWER SUPPLY... This can be found by a good pair of eyes!

Hello Thanks microman Today we conducted testing of profibus communication by using profibus tester (Profi-TM Professional) during the testing it shows a good communication signal, i attached the recent diagnostic buffer i extracted in reference with the alarm happen recently. I suspected that it is lose its communication suddenly that is why there is an access error recorder and at the event 69 it stop already. I will check all the profibus connector and cables for visual problem and will update you again regarding the problem. Thanks AttachmentDiagnose1.rar (230 Downloads) |

And this is the last Diagnostic buffer i was able to save for some reference. The other diagnostic shows in other stations that's why it is difficult to trace the problem since it is jumping from one station to the other.
