: Second data source
D
: Operation result
Description:
1. A logical OR operation is performed on the bit patterns of the contents of the two source
addresses (
S
2
and
S
1
). The result of the logical OR is stored in the destination device (
D
).
2. For 32-bit operation please refer to the DOR instruction.
Program Example:
When X0 = ON, the 16-bit data source D0 and D2 are analyzed and the result of the logical WOR
is stored in D4.
