Note4.3 Note4.3
The number of slots of base units is set in Base mode.(
(a) In Auto mode
The number of slots is determined as the available number of modules mounted
to each base unit.
5 slots are assigned to a 5-slot base unit, and 12 slots are assigned to a 12-slot
base unit.
(b) In Detail mode
The number of slots set in the I/O assignment setting of the PLC parameter dialog
box is used.
The I/O numbers are assigned to the modules from left to right consecutively, starting
from 0 assigned to the module on the right of the CPU module in the main base

POINT
One Redundant CPU occupies 2 slots.
Hence, the I/O number of Slot 1 (on the right of the Redundant CPU) is X/Y0.
Main base unit (5 slots)
I/O No. on right of Redundant CPU (Slot 1) is X/Y0.
