Explanation of function and operation

all at once.
• If the device number range is exceeded, data is transferred within the possible range.
Transfer is enabled even if the transfer number range is overlapped.
To prevent overwriting before transfer of source data, data is automatically transferred in the order "[1]
→ [2] → [3]"
according to the number overlap status.
