discrete symbolic,
I/O variable
No
Bit reference in
a non-BOOL
variable
R, P, L, AI, AQ, W,
non-discrete
symbolic, I/O
variable
IN
The source of the data to copy into the output
Q. This can be either a constant or a variable
whose reference address is the location of the
first source data item to move.
IN must have the same data type as the
variable in the Q parameter.
If IN is a BOOL variable or a bit reference, an
%I, %Q, %M, or %T reference address need not
be byte-aligned, but 16 bits beginning with the
reference address specified are displayed
online.
DINT, DWORD,
INT, REAL,
LREAL, UINT,
WORD, or bit
reference in a
non-BOOL
variable
All. S, SA, SB, SC
allowed only for
WORD, DWORD,
BOOL types.
No
LEN
The length of IN; the number of bits to move.
If IN is a constant and Q is BOOL:
1  LEN  16;
If IN is a constant and Q is not BOOL:
1  LEN  256.
All other cases: 1  LEN  32,767
LEN is also interpreted differently depending
on the data type of the Q location. For details,
see discussion under Move Data.
Constant
Constant
No
ENO
Indicates whether the operation was
successfully completed.
If ENO = ON (1), the operation was initiated.
Results of the operation are indicated in the FT
output.
If ENO = OFF (0), the operation was not
performed. If EN was ON, the FT output
indicates an error condition. If EN was OFF, FT
is not changed.

variable
Q
The location of the first destination data item.
Q must have the same data type as the
variable in the IN parameter.
If Q is a BOOL variable or a bit reference, an %I,
%Q, %M, or %T reference address does not
need to be byte-aligned, but 16 bits beginning
with the specified reference address are
displayed online.
