I/O Allocations
In CS1 PLCs, part of the I/O memory is allocated to each Unit. Units are divided into the following 3 groups for allocations.
• Basic I/O Units
• Special I/O Units
• CS1 CPU Bus Units
Basic I/O Units
Special I/O Units
CS1 CPU Bus Units
Allocations to Basic I/O Unit Groups
Basic I/O Units include CS1 Basic I/O Units, C200H Basic I/O Units,
and C200H Group-2 High-density I/O Units.
Allocated words in the CIO Area: CIO 0000 to CIO 0319
Basic I/O Units can be mounted to the CPU Rack, CS1 Expansion
Racks, and C200HX/HG/HE Expansion I/O Racks.
Note: CS1 Basic I/O Units cannot be mounted to C200HX/HG/HE
Allocation Methods
1. CPU Rack
Basic I/O Units on the CPU Rack are allocated words left to right; Units
are allocated as many words as required in word units. With CPU Ver.
2.0 and higher it is possible to specify start addresses per rack or per
slot.

Note
CIO Area:
CIO 0000 to CIO 0319 (See Note 1.)
(Memory is allocated in word units in order of mounting position in the Racks.)
Allocations
CS1 CPU Bus Unit Area:
CIO 1500 to CIO 1899
(Each Unit is allocated 25 words based on its unit number.)
Allocations
Special I/O Unit Area:
CIO 2000 to CIO 2959
(Each Unit is allocated ten words based on its unit number.)

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.
The Rack's first word setting can be changed from the default setting
(CIO 0000) to any word from CIO 0000 to CIO 9999. The first word
setting can be changed only with a Programming Device other than a
Programming Console.
Some Units classified as I/O Units (namely C200H High-density I/O
Units) are actually treated as Special I/O Units.
Although there are 96 unit number settings, a maximum of 80 Units
can actually be mounted to a PLC because that is the maximum
number of slots possible.
