 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 NY-series Controller. Both the memory configu-
ration 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 NY-series Controller.
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 NY-series Controller.

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