1
: First data source
S
2
: Second data source
D
: Operation result
Description:
1. Logical Double word AND operation.
2. A logical AND 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 AND is stored in the destination device (
D
).
3. For 16-bit operation please refer to the WAND instruction.
Program Example:
When X1 = ON, the 32-bit source (D11, D10) and (D21, D20) are analyzed and the result of the
logical DAND (Double word AND) is stored in (D41, D40).
