S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
1. 16-bit operation (WXOR and WXORP)
The exclusive logical sum (XOR) 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 exclusive 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
