Allocating First Words to Racks
I/O Allocations to CPU Bus Units
Unit
Note The first words for Racks cannot be set at the same time as the first words for
Each CPU Bus Unit is allocated 25 words in the CPU Bus Unit Area
(CIO 1500 to CIO 1899) according the unit number set on the Unit. CPU Bus
Units can be mounted to the CPU Rack or CS-series Expansion Racks.
The following table shows which words in the CS-series CPU Bus Unit Area
are allocated to each Unit.
CS-series CPU Bus Units are ignored during I/O allocation to Basic I/O Units.
Slots containing CS-series CPU Bus Units are treated as empty slots and
aren’t allocated any words in the I/O Area.
The following example shows the I/O word allocation to Basic I/O Units, Spe-
cial I/O Units, and CS-series CPU Bus Units in the CPU Rack of a Single CPU
System.
In the CS-series PLCs, the first word allocated to each Rack can be set with
the CX-Programmer’s I/O table edit operation. For example, the CPU Rack
can be set to be allocated words starting with CIO 0000; the next Rack, words
starting with CIO 0100; the next Rack, words starting with CIO 0200; etc. This
can make it easier to check word allocations to Units without calculating all the
way from the CPU Rack.
