Simultaneous and parallel engineering
The host applications can be designed using the tag names of the PLC and HMI. Parallel development will shorten the design time.

Case 
Previously, the PLC program was first
created and then the ladder program
was referenced to create the screens.
. With the CX-Programmer, the address
for the tag named “Number_produced” is
changed from D to H.
. Applications and the HMI 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 H.
Case 
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
HMI programming can be performed
in parallel.
Minimize side effect of address changes
It is possible to access memory with tags, so the HMI and host application are not aected even if the address of data in the
PLC is changed.
