Faster and Higher-capacity CPU Units

High-capacity data memory is in demand to meet the need for quality control for equipment and
products and to provide real-time processing and collection of measurement data. Large program
capacity is also in demand due to the need for improving program reusability through modularization
and structured programming.

Great Expanded Program Capacity and Data Memory Capacity

Ample capacity is provided for the data required for control operations.

The High-capacity CJ2H-CPU68-EIP Is Now Available.

» Program capacity: 400 Ksteps (1.6 times larger than before)
» Data memory capacity: 832 Kwords (2 times larger than before)
» Basic Instructions (0.016 µs)

Networks Are More Open

EtherNet/IP is an open network that uses the TCP/IP protocol on EtherNet networks, which are widely used
in offi ces and factories throughout the world. The CJ2 CPU Units support EtherNet/IP as a standard feature.
Because EtherNet/IP uses TCP/IP, it provides the many advantages of EtherNet technology.

Universal EtherNet and FA Data Links Can Be Used at the Same Time.

NEW

With EtherNet/IP, One Port Is Enough.

FTP Communications, Data Links, and Support Software Can Be Used Simultaneously through
a Single Port.

The CJ2 CPU Units provide as standard equipment a multifunctional EtherNet port that supports EtherNet/
IP. There is no need to add an EtherNet Unit, because universal EtherNet communications, such as data links
between PAC’s, message communications between PAC’s, and FTP transfers, are all enabled simultaneously
through this one port while Support Software is connected.

The memory size of the EM Area for automatic
address allocation in CX-Programmer symbol tables
has been expanded to a maximum of 240 Kwords.
When a tag is automatically allocated, data link
design and access from the host are enabled with
no need to be conscious of addresses. Moreover,
bits can be force-set/reset in the areas in which
data is automatically allocated.

No Need for Memory Map Control.

The CJ2 CPU Units introduce a new feature called tag access, to reduce your TCO (Total Cost of Ownership)
for systems that use Programmable Terminals, multiple PAC’s, and host applications. Tags allow freedom from
memory maps.

Simultaneous Development Takes the Stress Out of Short Deadlines.

NEW

No Need for Address Allocation Adjustments in Post-processing.

The various Controllers do not depend on addresses, so parallel development at each Controller is enabled
by first simply determining the tag names. There is no need for subsequent address allocation.

Example: Programmable Terminal and CJ2 Development

Previously

By simply setting tag names, PAC and
Programmable Terminal programming
can be performed in parallel.

The PLC program is first
created, and then the ladder
program is referenced to
create the screens.

The screen graphics are
created in advance, and
then addresses are allocated
and checked after the ladder
program is completed.

Programmable Terminal screens can be designed
using tag names defined in the CJ2 CPU Unit. There
is no need to adjust address allocations in post­processing.

» Data Links between CJ2 CPU Units

Simply setting tag names allows development to
proceed simultaneously among multiple designers
and multiple vendors. It is then easy to subsequently
change the sizes of data links.

The screens are created with no need
to pay attention to addresses.

» Simultaneous Development for Host Application
and CJ2 CPU Unit

Designing can be carried out simply by setting tag
names in the information section and the control
design section. There is no need for physical ad­dresses in the network interface specifications.

The Ease of Changing Designs Makes It
Simple to Add or Upgrade Equipment.

There is little effect on address changes.
Previously, when data was exchanged by
address specifi cation and addresses were
changed, the program had to be changed at
other Controllers and various operations, such as
memory checks, had to be performed. Now, tag
names eliminate the dependence on a memory
map and the need for checking items affected
by changes. This allows equipment to be easily
added or upgraded.

Assurance of Quality, Free from Mistakes.

Tags can be shared among the CJ2 CPU Units,
NS-series PTs and Middleware. Tag names can
be shared among controllers that exchange
data using the CX-One or Excel import/export
functions. Because redundant address entry and
address allocation are not needed, checking is
also not required. This makes it easy to construct
high-quality systems.

What is Tag Access?

NEW

A tag is a name given to an address. Tags are
managed in the CJ2 CPU Unit, where they are
defi ned as network symbols. The common user­defi ned tag names are used from Programmable
Terminals and host applications to access memory
in a CJ2 CPU Unit without knowing the actual
memory address.

More Flexible Programming

The Greatest Program Diversity in the industry. A programming environment has been created that is highly
readable and can flexibly support changes in specifications, to enable efficient design and program entry
with few mistakes.

Highly Readable Programming

Programs are easy to see and easy to understand.

Bit Addresses can be used in the DM Area and EM Area.

NEW

DM and EM Area bits could not be specified with the previous
SYSMAC PLCs, but they can with the CJ2 CPU Units.

Examples
D100.05: Bit 05 of D100

E0_100.05: Bit 03 of E0_100

BCD and Binary Timer Instructions can be used Together.

NEW

With the CJ1 CPU Units, it was necessary to select in the initial setup of the CPU Unit whether BCD or binary
was to be used as the data format for timer instructions. With the CJ2 CPU Units, BCD or binary can be
selected individually for each instruction by setting the data format of the timer set value.

Address Offsets can be Specified

NEW

An offset can be specified in brackets after a starting
address to offset the starting address. If an address
in I/O memory is specified as the offset, the final
address can be dynamically specified according to
the contents of the specified memory address.

Example
D100[W100]: D100 is the starting address and the contents of W100
is the offset. If W100 is &5, then D105 is specified.

Array Variables make Data Specification Easier to Understand.

By using array variables, any data in a string of
data can be expressed using a subscript, making
programming easy to understand. Array variables
can also be used for data stacks and function block
I/O variables. Because they can be set for network
symbols, the exchange of multiple data items

14

with external devices can be easily programmed.
(Usable languages: Ladder, ST, SFC).

Note 1. “Packets per second” is the number of communications packets that can be processed per second.

2. Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the data size. Application is supported between CS/CJ-series PLCs.
When connecting to devices from other manufacturers, make sure that the devices support the Large Forward Open specification.

3. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.

4. When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a timeout will temporarily occur at the other node that was
communicating with that port, and it will then recover automatically.

5. The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using a switching hub that supports IGMP snooping.

Performance Specifications

International Standards

• The standards indicated in the “Standards” column are

those current for UL, CSA, cULus, cUL, NK, and Lloyd
standards and EC Directives as of the end of May 2008.
The standards are abbreviated as follows: U: UL, U1: UL
Class I Division 2 Products for Hazardous Locations, C:
CSA, UC: cULus, UC1: cULus Class I Division 2 Products
for Hazardous Locations, CU: cUL, N: NK, L: Lloyd, and CE:
EC Directives.

• Ask your OMRON representative for the conditions under

which the standards were met.

● EC Directives

The EC Directives applicable to PAC’s, PLC’s include the
EMC Directives and the Low Voltage Directive. OMRON
complies with these directives as described below.

● EMC Directives Applicable Standards
EMI: EN61000-6-4, EN61131-2
EMS: EN61000-6-2, EN61131-2
PAC’s, PLC’s are electrical devices that are incorporated
in machines and manufacturing installations. OMRON
PAC’s, PLC’s conform to the related EMC standards so
that the devices and machines into which they are built
can more easily conform to EMC standards. The actual
PAC’s, PLC’s have been checked for conformity to EMC
standards. Whether these standards are satisfied for
the actual system, however, must be checked by the
customer.
EMC-related performance will vary depending on the
configuration, wiring, and other conditions of the equipment
or control panel in which the PAC, PLC is installed. The
customer must, therefore, perform final checks to confirm
that the overall machine or device conforms to
EMC standards.

● Low Voltage Directive
Applicable Standard:EN61131-2
VDC must satisfy the appropriate safety requirements.
With PAC’s, PLC’s, this applies to Power Supply Units and
I/O Units that operate in these voltage ranges.
These Units have been designed to conform to
EN61131-2, which is the applicable standard for PAC’s
and PLC’s.

After selecting a Power Supply Unit based on considerations such as the power supply voltage, calculate the current and power
requirements for each Rack.

Condition 1: Current Requirements
There are two voltage groups for internal power consumption: 5 V and 24 V.
Current consumption at 5 V (internal logic power supply)
Current consumption at 24 V (relay driving power supply)
Condition 2: Power Requirements

For each Rack, the upper limits are determined for the current and power that can be provided to the mounted Units. Design the
system so that the total current consumption for all the mounted Units does not exceed the maximum total power or the maximum
current supplied for the voltage groups shown in the following tables.
The maximum current and total power supplied for CPU Racks and Expansion Racks according to the Power Supply Unit model
are shown below.

Note 1. For CPU Racks, include the CPU Unit current and power consumption in the calculations. When expanding, also include the current and power consumption

of the I/O Control Unit in the calculations.

2. For Expansion Racks, include the I/O Interface Unit current and power consumption in the calculations.
