In CS-series PLCs, memory must be allocated to the Units mounted in the
PLC. I/O tables containing the models and locations of all Units and the allo-
cations made to each must be created and these I/O tables must be regis-
tered in the CPU Unit. When the power supply is turned ON to the CPU Unit,
the I/O tables are compared against the mounted Units to verify their accu-
racy.
Memory is allocated differently to Basic I/O Units, Special I/O Units, and CS-
series CPU Bus Units.
Allocation
Note
I/O Area
CIO 0000 to CIO 0319 (See note 1.)
(Memory is allocated in one-word
units based on mounting position in
the Racks.)
1. The Rack's first word setting can be
changed from the default setting (CIO 0000)
to any word from CIO 0000 to CIO 0999.
The first word setting can be changed only
with a Programming Device other than a
Programming Console.
2. The unit number setting on the front of
C200H Group-2 High-density I/O Units is
ignored. Words are allocated to these Units
based on their location in the Rack, just like
Basic I/O Units.
