Dear user,

The pictures you shared don't help that much to find out the entire scenario.Please save the diagnostics buffer of both CPUs as a text file and share them here to help you what is the exact cause of trouble.To do so, connect to each CPU,Select it in STEP 7 and CTRL+D.In the Diagnostics buffer tab , select Save as.

I hope it helps,
