Cause and
correction
Assumed cause Correction Prevention
A Unit model or Special Unit unit num-
ber in the Unit Configuration in the
CPU Unit is different from the Unit
model or the Special Unit unit number
of the Unit that is mounted in the Con-
troller.
Correct the Unit Configuration in the
CPU Unit or the physical Unit configu-
ration so that there are no inconsis-
tencies.
Make sure that the Unit Configuration
in the CPU Unit and the physical Unit
configuration are consistent.
