There are "Auto" and "Detail" modes to assign the number of modules of the main and
extension base units of Basic model QCPU.
(1) Auto mode
In Auto mode, the number of slots is assigned to the base units according to that
of the installed main and extension base units.
The I/O numbers are assigned according to the modules which can be installed
to the current base unit.
Since the AnS series main and extension base units were fixed to eight slots, a
three/five-slot base unit occupied eight slots.
The Basic model QCPU, which occupies only the installable slots of a base unit,
occupies only three slots when a three-slot base unit is used.
