Dear user,
Please tell us about all CPU LED status in Master and stand-by CPU.As the starting point, you can try checking the slave number #5 over PROFIBUS subnet connected to the "DP master system ID: 2" that is possibly on CPU on rack#1.If you have a faulty slave module or faulty connector, please rectify it.You can go online on HW Config editor with the hints from section 5.3 of THIS MANUAL for more root cause analysis. I hope it helps, hdhosseini |

Thank you for your reply hdhosseini I have checked HW in online and saw that the PS 407 is not available there. A few years ago someone has changed PS |
