• Confirm that the Unit is connected properly.
• Check the I/O table with the I/O Table Verification operation
and correct it if necessary. After correcting it, perform the I/O
Table Create operation.
• The CPU Bus Unit model registered in the I/O tables does
not match the model of CPU Bus Unit actually mounted.
Check the I/O tables with the I/O Table Verification operation
and correct it if necessary.
After correcting the I/O tables, perform the I/O Table Create
