 Note: The instruction supports V devices and Z devices. (If the 16-bit
instruction is used, Z devices can not be used. If the 32-bit
instruction is used, V devices can not be used.)
Please refer to specifications for more information about device
ranges.
If KnX/KnY/KnM/KnS is used, it is suggested that X/devices/Y
devices/M device numbers/S device numbers should start from a
number which is a multiple of 16 in the octal numeral system or in the
decimal numeral system, e.g. K1X0 (octal numeral system), K4SY20
(octal numeral system), K1M0 (decimal numeral system), and K4S16
(decimal numeral system).

Explanation
 S: Initial word device which is moved; D: Initial word device which is moved; n
1
:
Number of values which are moved; n
2
: Number of values forming a group
 The values in the n
1
word devices starting from D are divided into groups (n
2
values as a group), and these groups are moved leftwards. The values in the
n
2
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 the operand S is KnX/KnY/KnM/KnS, the operand D can be a counter, timer,
or a data register. If the operand D is KnY/KnM/KnS, the operand S can be a
counter, timer, or a data register.
 If the operand S is KnX/KnY/KnM/KnS, and the operand D is KnY/KnM/KnS,
Kn in KnX/KnY/KnM/KnS which is S and Kn in KnY/KnM/KnS must be the
same.

Example
 When X0 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.
 The values in the word devices are moved leftwards in the order ~ during a
scan cycle.
