y Note:

1. If S

, S

and D are used in device F, only 16-bit instruction is

applicable.

16-bit instruction (7 Steps)

WAND

Continuous

execution

32-bit instruction (13 Steps)

DAND

Continuous

execution

y Flags: None

Operands:

: Source data device 1

: Source data device 2

: Operation result

Explanations:

1. This instruction conducts logical AND operation of S

and S

and stores the result in D.

2. Operation rule: The corresponding bit of the operation result in

D will be “0” if any of the bits in S

“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).
