Hi, First step should be checking PLC manual for troubleshooting and LED codes and then check diagnostic buffer. Also you can try to reset PLC and MMC http://support.automation.siemens.com/WW/view/en/29801950 |

The cpu doesn't respond. The cpu is around 9 years old, i think the warranty is not. Have you got the same problem with another s7 300 CPU ? Thanks |
