(2) Detail mode
In Detail mode, the number of modules can be set for each base unit in the <<I/O
assignment settings>> tab of C Controller setting utility.
(a) Application
Since an empty slot occupies one slot if 0 point is assigned to it, this mode is used
to make unused slots unassigned.
(b) Precautions for setting the number of slots
Any number of slots can be set regardless of the number of modules used.
Set the number of slots for all base units used.
I/O assignment may not function properly if the setting is not performed for all
base units.
The following describes what happens if the set number of slots is different from
the actual number of slots used on a base unit.
1) When the set number of slots is greater than the number of slots used on the
base unit
The slots for the set quantity are occupied.
The slot numbers after the used ones are assigned as empty slots.
For example, using five slots in the 8-slot base unit setting will leave three slots
empty.
The number of empty slots is the one set in the <<System settings>> or <<I/O
assignment settings>> tab of C Controller setting utility.
(The default is 16 points.)
