S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
BMOV instruction transfers "n" points of data from to at one time.
• 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.
Operand Type Description Data Type
Transfer source data or device number storing data 16-bit binary
Transfer destination device number 16-bit binary
n Number of transferred points (including file registers) [n ≤ 512] 16-bit binary
