Important Case Examples

When you exchange structure variable data between an NY-series Controller and a remote device, you
must align the memory configuration of the structure variable members with those of the remote device.
This section describes what to do in either the NY-series Controller or in the remote device.
Additional Information
This is not necessary when you exchange data between NY-series Controllers.
Aligning the Memory Configuration with a Remote Device
There are two methods that you can use to align the memory configuration with a remote device.
For example, the differences in the memory configuration for structure variables between an NY-
series Controller and a CJ-series CPU Unit are shown below.
This section describes how to align the memory configuration for these Units.
