Troubleshooting using the IO Controller indicators
Section 8-2

8-2-3-5 CPU Unit exchange
Backplane Bus error
/i
Likely cause
The PROFINET IO controller encountered an error while assessing the
backplane bus of the PLC.
IO Controller Unit response
The Unit will stop processing. Records the error in the error log.
CIO Area Flags allocated to the IO Controller Unit
None of the bits is set.
Correction
Restart the PLC. Check the PLC for faults in the backplane bus. Replace the
IO-Controller or other Units if the error recurs.
Unit number duplication
/i
Likely cause
At startup the PROFINET lO Controller detected that there is another Unit
having the same Unit number set.
IO Controller Unit response
The Unit will stop processing.
CIO Area Flags allocated to the IO Controller Unit
None of the bits is set.
Correction
Correct the Unit number of the IO Controller or the other Unit. Restart the PLC.
CPU Unit fault
/i
Likely cause
The PROFINET lO Controller detected that PLC CPU Unit is faulty.
IO Controller Unit response
The Unit will stop processing.
CIO Area Flags allocated to the IO Controller Unit
None of the bits is set.
Correction
Replace the CPU Unit if the error recurs when the CPU Unit is restarted.
