Function and operation explanation
1. When a bit device is used
A device described in OUT instruction turns ON or OFF according to the driven contact status.
Parallel OUT instructions can be used consecutively as many times as necessary.
In the program example shown below, OUT M100 and OUT M101 are parallel.
If two or more OUT instructions are executed for a same device number, however, the double output (double
coil) operation is resulted.
2. Indexing
Devices used in OUT instruction can be indexed with index registers (V and Z).
(State relays (S), special auxiliary relays (M), or "D
.b" cannot be indexed.)
Applicable only to the FX
3U and FX3UC PLCs.
When a used devices is an input (X) or
output (Y), the value of an index register (V
or Z) is converted into an octal number, and
then added.
Example: When the value of Z0 is "20",
Y024 turns ON or OFF.
3. Bit specification of data register (D)
A bit in data register (D) can be specified as a device used in OUT instruction.
Applicable only to the FX
3U and FX3UC PLCs.
When specifying a bit in data register, input
"." after a data register (D) number, and then
input a bit number (0 to F) consecutively.
Only 16-bit data resister is applicable.
Specify a bit number as "0 1, 2, ..., 9, A, B,
..., F" from the least significant bit.
Example: In the example shown on the left,
the bit 3 of D0 turns ON or OFF
when X000 turns ON or OFF.
