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

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

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.
Specific Example
1. With the CX-Programmer, the address for the tag named
“Number_produced” is changed from D100 to H200.
Tag name
Number_produced
Address
D100
Change
Number_produced H200
2. 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.
No change required.
Host application
Number_produced
Number_produced
Accessed using a tag.
