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).
