Hi all.
About a week ago my CPU went to stop mode with error 494D. I belive that IO error means not signal modules (i have all OBs needed for error handling), but internal communication. After that CPU doesn't start until power off. Siemens support said, that this problem caused by defective module and/or backplane bus. Futher information is not avaiblу so they adviced to check every module. The problem is - i can't check every module (2 racks ~approx. 30 modules). Problem first appeared after 2 weeks of uninterrupted work - so it would take more than a year to check out what module should be removed. I have 7-9 days only because system must be started in that time and we can't also order new modules due to delivery time.
In attachement you can see station confuguration and diagnostic buffer.

I have all OBs, but in fact no OB is called on STOP. |

Cause unknown, was solved by replacing CPU. Sorry, cant remember details - it was nearly 10 years ago |
