Hi Muneeb, After power down and power on you might be reaching the CPU again and read out the Diagnostic Buffer. There will be given some error codes that might be pointing in the direction of the problem. It could be that a update of the firmware is possible and the DEFECTIVE status will never come again. But there fore is a diagnostic buffer and the MLFB number of your CPU 414 necessary.... [:o] The DEFECTIVE status is coming when there is no solution for something that is called, going further could be dangerous....[;)] So please place the diagnostic buffer on the forum so I could look to it. You may also look for yourself at Operating System Updates for S7-414-CPUs |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
