Operands:
S
: Source of data
m
1
: Start digit to be moved of the source data
m
2
: Number of digits (nibbles) to be moved of the
source data
D
: Destination device
n
: Start digit of the destination position for the moved digits
Explanations:
1. This instruction is able to re-allocate or combine data. When the instruction is executed,
m
2
digits of contents
starting from digit
m
1
(from high digit to low digit) of
S
will be sent to
m
2
digits starting from digit
n
(from high digit
to low digit) of
D
.
2. Range:
m
1
= 1 ~ 4;
m
2
= 1 ~
m
1
;
n
=
m
2
~ 4
3. See the specifications of each model for their range of use.
4. M1168 is designated by SMOV working mode. When M1168 = On, the program is in BIN mode. When M1168 =
Off, the program is in BCD mode.
Program Example 1:
1. When M1168 = Off (in BCD mode) and X0 = On, the 4
th
(thousand) and 3
rd
(hundred) digit of the decimal value
in D10 start to move to the 3
rd
(hundred) and 2
nd
(ten) digit of the decimal value in D20. 10
3
and 10
0
of D20
remain unchanged after this instruction is executed.
2. When the BCD value exceeds the range of 0 ~ 9,999, PLC will determine an operation error and will not execute
the instruction. M1067, M1068 = On and D1067 records the error code OE18 (hex).

Before the execution, assume D10 = K1234 and D20 = K5678. After the execution, D10 will remain unchanged and
D20 will become K5128.
