This function block computes the logical XOR of 2 input BIT signals. This means the output is logical 1 if the two input signals are different. All input signals, as well as the output signal can be negated.


Name I/O Type(s) Function
P0 I BIT First input signal
P1 I BIT Second input signal
Q O BIT Result


The parameter dialog can be used to select the negated signals.


If the output Q is logical 1, the function block will be highlighted.
