2. Set data

3. Applicable devices

S: This function is supported only in FX3U/FX3UC PLCs.

Explanation of function and operation

1. 16-bit operation (WAND and WANDP)

The logical product (AND) operation is executed to the contents of and in units of bit, and the result is

transferred to .

• While the command input is OFF, the data of the transfer destination does not change.

• While the command input is ON, the data of the transfer sources and do not change.

• When a constant (K) is specified in the transfer sources and , it is automatically converted into the

binary format.

• The logical product operation is executed in units of bit as shown in the table below (1 ∧ 1 = 1, 0 ∧ 1 = 0, 1 ∧ 0 = 0,

0 ∧ 0 = 0).

1: ON, 0: OFF
