Operands:
S
1
: Source data device 1 S
2
: Source data device 2 D: Operation result
Explanations:
1. Logical double word (32-bit) OR operation.
2. This instruction conducts logical OR operation of S
1
and S
2
in 32-bit mode and stores the
result in D.
3. If operands S
1
, S
2
,
D use index F, then only a 16-bit instruction is available.
Program Example:
When X1 is ON, the 32-bit data source (D11, D10) and (D21, D20) are analyzed and the operation
result of the logical OR is stored in (D41, D40).
