Automatic User Memory Recovery
Finer memory production processes have been
accompanied by problems such as bit corruption
caused by cosmic rays. With the CJ2 CPU Units,
corruption in the user program is detected and the
program recovered in real time before program
execution. This reduces equipment down time by
minimizing the number of times that operation is
stopped due to memory errors.

Networks Are More Open
EtherNet/IP is an open network that uses the TCP/IP protocol on EtherNet networks, which are widely used
in offices 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.
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.
Create a Seamless Data Flow in a Single Network System.
Because it is based on the world-standard CIP open protocol, a seamless data flow can be achieved between
control lines and information monitoring lines in a single network system. From here on, EtherNet/IP will be
increasingly used in multi-vendor environments (such as robotics and safety devices).

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.
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
NEW
The screens are created
Addresses are determined while
creating the ladder program.
The screens are created with no need
to pay attention to addresses.
» Simultaneous Development for Programmable
Terminal and CJ2 CPU Unit
Programmable Terminal screens can be designed
using tag names defined in the CJ2 CPU Unit. There
is no need to adjust address allocations in post-
processing.
» 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 ad-
dresses in the network interface specifications.
» 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 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.

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 specification 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.

No change required.
Even after the change, the
number of items produced
is acquired correctly from
H200.

dress for the tag named “Number

to H200.

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