Hi, I enclosed the error list of S7-400 that make EXTF error appear. Please help me to find out which the root cause that make EXTF active. The existing program is the old one, before the machine shutdown for not operation. I have the back up program but is it neccessary to download it to the cpu. indra Attachments7error.zip (597 Downloads) |

Hello isurya please check what firmware version you have in your CPU, it could very well bethat you"suffer" from the problem described in the link below: Why does the EXTF LED light continuously on a CPU 300 (V1.0.0)/CPU 400 (V1.1.0) after occurrence of a diagnostics alarm? If it is not that, it would be wise to update the firmware to the latest version for your particular CPU anyhow. I hope this helps |
Cheers |
