/i
Likely cause
The PROFINET IO controller encountered an internal error and can not
continue.
IO Controller Unit response
The Unit will stop processing. Records the error in the errorlog.
CIO Area Flags allocated to the IO Controller Unit
None of the bits is set.
Correction
Restart the IO Controller. Replace the IO-Controller if the error recurs.

Correction
Restart the IO Controller. Replace the IO-Controller if the error recurs.
/i
Likely cause
The PROFINET IO controller encountered an error while aceesing the
backplane bus of the PLC.
IO Controller Unit response
The Unit will stop processing. Records the error in the errorlog.
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
