Operands:
S
1
: Source data device 1 S
2
: Source data device 2 D: Operation result
Explanations:
1. If
S
1
, S
2
and D are used in device F, only 16-bit instruction is applicable.
2.
See the specifications of each model for their range of use.
3.
This instruction conducts logical AND operation of S
1
and S
2
and stores the result in D.
4.
Operation rule: The corresponding bit of the operation result in D will be “0” if any of the bits in S
1
or S
2
is
“0”.
Program Example 1:
When X0 = On, the 16-bit D0 and D2 will perform WAND, logical AND operation, and the result will be stored in D4.

Program Example 2:
When X1 = On, the 32-bit (D11, D10) and (D21, D20) will perform DAND, logical AND operation, and the result will be
stored in (D41, D40).
