2. 32-bit operation (DAND and DANDP)
The logical product (AND) operation is executed to the contents of [
+1,
] and [
+1,
] in units of
bit, and the result is transferred to [
+1,
].
• While the command input is OFF, the data of the transfer destination [
+1,
] does not change.
• While the command input is ON, the data of the transfer source [
+1,
] [
+1,
] do not
change.
• When a constant (K) is specified in the transfer source [
+1,
] [
+1,
], it is automatically
converted into 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
