I/O number assignment example without no extension base on the 1st extension stage
I/O numbers are assigned assuming that every base unit has 8 slots.
If a 5-slot type base unit is used, an I/O number obtained by adding points equivalent
to 3 slots (48 points) to the final I/O number of the 5-slot base unit is assigned to the
next extension base unit.
