mr.adi Posts: 112 Rating: (0)	Hello guys. i have installed cpu 315-2DP. It works well, but sometimes it goes to STOP mode and turn on the SF led. If i change the key from RUN mode to STOP mode and than from STOP to RUN, it works well again. I check all module and looks fine. Can you help me how can i find a solution for this case please? My HW configuration is like in a photo. Thanks Adi ------------------------------------------------------------------------------------------ Split from cpu 315-2DP only SF and BF LED Flashing..

To see where the problem is exactly the complete diagnostic buffer log is needed. You can save it to textfile with the button "save as" and attach this file here, so why should this be a problem? Regards Christoph

Why its important to create now this OB? hi, you can export the diagnostic buffer with the button "save as" The CPU don´t get in Stop because off the error. It goes in Stop because it wants to call an OB when the error occurs. If this OB is not loaded, the CPU can not call this OB and goes into Stop. hope this helps, regards,
