Note 1 When specifying Expansion Operation Data, be sure that the area does not overlap with other
areas that are in use.
If areas overlap, the memory may be overwritten and unexpected operation may occur.
2 These contents are the same as those output to device variables for CJ-series Unit
*_PVAlmSta, *_Ch#_L_PVAlmSta, and *_Ch#_H_PVAlmSta for Operation Data.
3 The CJ1W-AD04U does not have structure data types for Expansion Operation Data.
