WAND, WANDP: 7 steps
DWAND, DWANDP: 9 steps
Operands:
S
1
: Source data device 1 S
2
: Source data device 2 D: Operation result
Explanations:
1. WAND instruction conducts logical AND operation of S
1
and S
2
and stores the result in D
2. When WAND is used as 16-bit instruction, Z device cannot be adopted; when WAND is used as 32-bit
instruction, V device cannot be adopted.
Program Example 1:
When X0 = ON, the 16-bit source D0 and D2 are analyzed and the operation result of the logical AND operation is
stored in D4.

Program Example 2:
When X0 = ON, the 32-bit source (D11, D10) and (D21, D20) are analyzed and the operation result of the logical
AND operation is stored in (D41, D40).
