 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 con-
figuration 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-series CPU Unit.

(2) Add the dummy variable b2 that you created in the
CJ-series CPU Unit to the NJ-series CPU Unit as well.
