Method 2: Changing the Memory Configuration of the Structure Variable in
the Remote Device
You can insert a member into the structure variable of the remote device to change it to match the
memory configuration of the structure variable in the NJ/NX-series CPU Unit.
Both the memory configuration and the data types must be the same between the two structure
variables. You therefore need to create the same members in both the remote device and the
NJ/NX-series CPU Unit.
Example: The following example shows how the memory configuration of the structure variable in
the CJ-series CPU Unit is changed to match the memory configuration of the structure variable in
the NJ/NX-series CPU Unit.

(2) Add the dummy variable b2 that you created in the
CJ-series CPU Unit to the NJ/NX-series CPU Unit as well.
(1) Add a dummy member variable b2 that matches the
unused memory location on the NJ/NX-series CPU Unit.
Make the following changes to align the memory
configurations in the NJ/NX-series and CJ-series CPU Units.
