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. |

Thanks Late, There is at least an old version of firmware in CP443-1 (&GK7 443-1EX11-0XE0), which in now V2.3. Quite an old one! There is no routing used, at least not in the situation when the fault occurred. The chain of events was the following: - small changes to the existing FC blocks was downloaded, no problems - suddenly, when downloading again a small change (FDB programming, in function CMP>I, theconstant value in IN2 was changed to another constant) the fault occurred. I will open a service request to Siemens Finland. Here You can also find a zip file of installed software. Thanks, Rauno AttachmentInstalled software 20070120.zip (669 Downloads) |
