Dear friends, Here is my ordeal now, I have a costumer who has a simatic touch panel controlling a CPU224 CN, and after a brief start the "STOP" and "SF" leds are on, so I tried to connect with the CPU and I have successfully uploaded the project and I tried to start the "online status" it showed me a message (please see attached), then I referred to the online "information" and it showed me a fatal error code 9, which seems to be a memory problem, then I referred to the manual and failed to get a solution. Please I need help. Regards. Tomy.

Hello Tomy, Looks like a memory problem indeed. Since you have a backup you can try a Clear PLC and download the program again. If that not works, use wipeout. exe to clear the PLC. If that doesn't work there is a big memory problem and no other option then to replace the CPU. Possible cause could be to many write actions on the internal eeprom, so check your backup program for these actions. See link how to write data on internal eeprom and the risk of doing that at high frequency : http://support.automation.siemens.com/WW/view/en/17471561 Good luck, regards Marcjan |

Dear friend, If the problem is about EEPROM writing, I think we should take a look to the code it self, so please look at network (11) and (12) in the "MAIN". (see attached) Could it be SMB31 value setting, please help Regards. Tomy.
