Dear experts I've encountered a problem with a S7-1510SP. According to the diagnostic buffer the CPU rebooted at 3:39AM and restarted on his own. But I can't figure out why the CPU state changed from RUN to OFF mode. What could be the cause of this state change? Thanks in advance.

Hi KilianDB, As you say, the event with reference "Event ID: 16# 02:400C" that appears in the diagnostic data of your CPU, simply indicates that the CPU has gone from START to RUN state. In order to find out possible causes of the behavior you are experiencing, and in order to gather as much information as possible, could you please attach the complete diagnostic buffer in .txt format? However, this kind of behavior can also be caused by a corruption of the internal FW of the CPU. Therefore, I recommend you to upgrade the FW of your CPU (6ES7 510-1DJ01-0AB0) to the latest available version which you can download from the following link: "Firmware upgrade for 1510SP-1 PN CPU" Best regards! |

I'll attach a printout off the diagnostic buffer. It seems in event 5 Event ID: 16# 02:4002 that there's a sudden shutdown. Thanks for the info about the firmware upgrade. Best regards AttachmentPLC_Diagnostics.txt (423 Downloads) |
