2. 32-bit operation (DSWAP, DSWAPP)
In the case of 32-bit instruction, too, lower 8 bits and higher 8 bits are swapped individually.

1) When the continuous execution instruction is used, it must be noted that the swap takes place in every
operation cycle.
2) Some restrictions to applicable devices.
S1: The FX
3U and FX3UC PLCs only are applicable.
