word devices starting from S are moved to the
vacant word devices in the word devices starting from D .

Generally, the pulse instruction WSFLP is used.

If KnM/KnS is used, it is suggested that M device numbers/S device
numbers should start from a number which is a multiple of 16 in the
decimal numeral system, e.g. K1M0 and K4S16 (decimal numeral
system).

When X0.0 is turned from OFF to ON, the values in the sixteen word
devices starting from D20 are divided into groups (four values as a
group), and these groups are moved leftwards.
