Hi,
After this I went in diagnostic to see what is the problem and I discovered this (the message I'm sending you in attach). As I understood, the I/O access error, writing message I received when the black out happened (time ~07:17). After that the PLC recovered (time ~07:31). I have no problems with the SW, everything is working just fine, but I still have this EXTF on. Just not to confuse you, I have EXTF also before the Balck out, but I couldn't find out what is it. Does someone has any idea looking the file message? Thanks, AttachmentDiagnose_2807.txt (319 Downloads) |

hi drozerce, I had a behavior like this on a older S7-400-CPU. The EXTF-LED was on all the time, without a failure. It was a firmware-bug. A FW-Update fixed it. I was looking in the firmware-notes of your PLC, but I didn´t find anything about that problem. I was searching further and found a FAQ, that may helps: The LED "DP EXTF" glows, although no PROFIBUS-net is connected to the integrated DP-interface hope this helps, regards, |

New question published by Ryan_Ryan is split to a separate thread with the subject Replace 414-2 CPU, does it affect the other modules connected. Best regards |
