Hi Aero, When the CPU have a command or situation thats not described in his internal program, then the CPU gives the blinking LEDs for the situation "DEFECTIVE". As Dec described you need some more information by reading out the diagnostic buffer and save that one and place it on the forum. On the internet you can check also which version of the firmware {FW} is the mewest for your CPU414: Operating System Updates for S7-414-CPUs[8)] The newest FW-version is V4.1.0, because you didn't mention the version of your CPU, there might be found some trouble what is "repaired".... [:P] When the FW is uptodate then please try to download a diagnostic buffer and send that to Siemens A&D. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
