Variable NJ_X Structure Y
To align the memory configurations in the NJ-series and CJ-series CPU Units, offsets are set in the Sysmac Studio.
Here, the following offsets are set for member c of data type Y of the structure variable NJ_X.

Set a byte offset of 6 and a bit offset
of 0 (no offset) for variable c.
