Controllers
Allocations to Basic I/O Unit Groups
Allocated words in the CIO Area: CIO 0000 to CIO 0079
Basic I/O Units can be mounted to the CPU Rack and Expansion Racks.
Allocation Methods
1. CPU Rack
Basic I/O Units on the CPU Rack are allocated words left to right (i.e.,
from the Unit nearest the CPU Unit) starting from CIO 0000. Units are
allocated as many words as required in word units. Words can be reser-
ved using the CX-Programmer.
Note: Units with between 1 and 16 I/O points are allocated 1 word (16
bits) and Units with between 17 and 32 I/O points are allocated
2 words (32 bits). For example, 8-point Relay Units are allocated
1 word, with bits 00 to 07 actually allocated to the I/O points.
2. Allocations to Expansion Racks
I/O allocation to Basic I/O Units continues from the CPU Rack to the
Expansion Racks. Words are allocated from left to right and each Unit
is allocated as many words as it requires in word units, just like Units in
the CPU Rack. A Rack’s first word setting can be changed set to any
word from CIO 0000 to CIO 9999 using a Programming Device.
Allocations to Special I/O Units
Each of these Units is allocated ten words in the Special I/O Unit Area
(CIO 2000 to CIO 2959).
Special /O Units can be mounted to the CPU Rack and Expansion
Racks.
Each Unit is allocated 10 words in the Special I/O Unit Area according
to its unit number, as shown in the following table.
Note: Special I/O Units are ignored during I/O allocation to Basic I/O
Units. Slots containing Special I/O Units are treated as empty
slots.
Allocations to CPU Bus Units
Each CPU Bus Unit is allocated 25 words in the CPU Bus Unit Area
(CIO 1500 to CIO 1899).
CPU Bus Units can be mounted to the CPU Rack or Expansion Racks.
Each Unit is allocated 25 words in the CPU Bus Unit Area according to
its unit number, as shown in the following table.
Note: CPU Bus Units are ignored during I/O allocation to Basic I/O
Units. The same unit numbers can be used for Special I/O Units
and CPU Bus Units.
Programming Consoles
Windows-based Programming Software: CX-One
Omron's integrated software for programming and configuration of all
control system components, including PLCs, HMI, drives, temperature
controllers and advanced sensors.
Note: CX-One includes the PLC programming tool CX-Programmer,
previously released as a separate package. CX-Programmer
Version 2.04 or higher is required to program CJ-series PLCs.
Up to 10 Units can be mounted.
