2. 32-bit operation (DXOR and DXORP)
The exclusive logical sum (XOR) 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 exclusive logical sum operation is executed in units of bit as shown in the table below (1
∀ 1 = 0, 0 ∀ 0 = 0,
1
∀ 0 = 1, 0 ∀ 1 = 1).
1: ON, 0: OFF
Program example
By combining WXOR and CML (FNC 14) instructions, the exclusive logical sum not (XORNOT) operation can be
executed.
