Smallest, Most Powerful Solution for
Tomorrow’s Advanced Production Systems
We shrank our most powerful programmable controller by 40% to fit industry’s
most space-confined cabinets. All of Omron’s outstanding performance was
retained in the process: That includes the mix of standard and special I/O
available, options for system expansion, and standardized programming across

High-Speed Processing
Seamless Communications
Cost and Space Savings
With separate communications and
processing bus structures, the CJ1 delivers
the fastest throughput for both advanced
and basic instructions for reliable sequential
action. Simultaneously, data queries of
various sizes and in locations across the
entire network can be processed without
delaying the cycle time.
The CJ1 delivers transparent communications across a variety of network types
and protocols: Ethernet, DeviceNet,
Controller Link and Serial communications.
This capability can allow a user to load
programs or acquire data from any location
in the facility.
With no rack to purchase and slim modules
that are easy to configure and assemble,
the CJ1 lowers overall system cost, takes
up little space and leaves you room for
future growth.

Five Reasons to Design CJ1 PLCs into Your Application
Ultra-compact Size
■
Approx. 40% smaller than mid-size controllers such as
CS1 and C200H
■
Measures just 90 mm H x 65 mm D; width depends on
modules selected. Modules are either 20 mm or 31 mm wide
■
Shallow 65 mm depth allows thinner control panels
■
Modules lock together to create a flexible “through plane”
eliminating the need for a backplane
Speed
■
Three CJ1 PLC part
numbers combine to
form a powerful 4-axis
motion controller that
can fit in the palm of
your hand
Control up to 2560 local I/O, plus 32,000 DeviceNet I/O using
multiple DeviceNet masters
■
Instructions to facilitate every application
❏
PID with auto-tuning ideal for multi-loop temperature control
and analog process I/O
❏
Floating-point decimal math operations ensure precise
positioning with X-Y tables
❏
Conversion between floating-point decimal and ASCII
character string data allows measuring device data to be used
in operations
❏
High-resolution line approximation allows conversion from a
level measurement in mm to tank capacity in liters according
to the shape of the tank
■
Built-in flash memory backup protects user program and
parameter areas
■
Optional Omron flash memory cards hold up to 64 MB of data to
transfer program modifications, load recipes for quick production
changeover or store logged data values from the CPU
One Platform Can Meet
All Your Control Needs
Standardizing on the CJ1 platform means that you have chosen a
control solution that can be scaled for systems from simple to the
most sophisticated. It all starts with choosing the CPU to fit your
needs. From there every application will use the same
Communications, Specialty, and Basic I/O modules. This versatility
preserves your hardware and training investment while delivering the
same look and programming feel for every application.

machine unit for flexible reconfiguration.
Manage production using data transferred
via network from the PLCs on each
machine to a personal computer.
• Use CJ1 in the multi-pouch weighing
unit to handle high-speed load cell
weight measurements and coordinate
transfer operations.
• Form-fill-seal machines 1 and 2 use CJ1
or CJ1M controllers to create two
different colored bags of product then
transfer it to the case packaging unit.
• The small box packager machine forms
flat stock into a box that holds multiple
bags of product. CJ1M coordinates
fabrication and gluing activities.
• Inspection, sealing and date/lot code
marking equipment are controlled by
CJ1. Data transferred to the PC for
finished packages gets archived for
production optimization and regulatory
record keeping.

Configuring a CJ1 System
This section provides tools to configure a CJ1G/H or CJ1M system. Included in this section are:
Basic Configuration
A CJ1 Series basic configuration consists of a CPU, power supply
unit, and up to 10 basic I/O, special I/O and bus units, and an end
cover. Add up the current consumption for all the modules and the
CPU according to the chart shown on page B-9, then select the
power supply unit suitable for the application.

If the number of modules per rack exceeds 10 or the current
consumption is greater than the capacity of the power supply units,
use the CPU and expansion rack configuration. This divides the load
from the modules across two power supply units. To allow
communication and automatic channel assignment in programming,
order an I/O control module for the CPU rack and an I/O interface
module on each expansion rack.

Where are ratings to calculate overall current consumption?
All the current consumption ratings for the CPU, basic I/O, special and CPU bus units are collected in tables on pages B-110 to B-111.
Which power supply is right?
Compare the current consumption total of basic I/O and special I/O modules, and CPU bus units to determine which power
supply to use. If more than 10 modules are required or the current consumption exceeds the output capacity of the power
supplies, configure the system using CPU and I/O expansion racks.
