Simultaneous and parallel engineering
The host applications can be designed using the tag
names of the PLC and PT. Parallel development will
shorten the design time.
EtherNet/IP
Support for data structures
This special feature is made possible by combining an
OMRON CJ2 PLC with an NS-series PT. The data
structures that you define on the Programming Tool can be
used on the CX-Designer simply by dragging and dropping
them.
Minimize side effect of address changes
It is possible to access memory with tags, so the PT and
host application are not affected even if the address of
data in the PLC is changed.

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
physical address.

2. For example, create screens with tag names without typing the physical address.
1. Tag names are managed at the PLC with the CX-Programmer.
FROMTO
By simply setting tag names,
PLC and Programmable
Terminal programming can be
performed in parallel.
Case 1
Previously, the PLC program was first
created, and then the ladder program was
referenced to create the screens.
Case 2
The screen graphics are created in
advance, and then addresses are allocated
and checked after the ladder program is
completed.
Design time is
shortened.
Addresses are determined
while creating the ladder
program.

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

Programmable Terminal
With the CX-Programmer, the address for the tag named
Number_produced” is changed from D100 to H200.
Specific Example
Applications and the PT are accessed using tags, and so
changes do not need to be made at other devices.
Even after the change, the number of items produced is
acquired correctly from H200.
