Command
input
FNC 26
WAND
• While the command input is OFF, the data of the transfer destination
• While the command input is ON, the data of the transfer sources
• When a constant (K) is specified in the transfer sources
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).
