各位大神，能否给我详细讲讲MOVE指令的用法

V_M00001 and V_M00033 are both WORD arrays of length 3, for a total of 48 bits in each array. Since Controllers do not recognize arrays, the Length operand has to be set to 3, for the total number of WORDs to be moved. When enabling input V_Q0014 is ON, MOVE_WORD moves 48 bits from the memory location %M00001 to memory location %M00033. Even though the destination overlaps the source for 16 bits, the move is done correctly, except on Series 90-30 CPU351, CPU352, and CPU36x CPUs, which do not allow overlapping.
