This function block computes the logical OR of up to 8 input BIT signals. This means the output is logical 1 if any of the input signals is logical 1. All input signals, as well as the output signal can be negated.


Name I/O Type(s) Function
P0 I BIT First input signal
Pn I BIT Other input signals (n=1 to 7)
Q O BIT Result


The parameter dialog can be used to define the number of input signals, as well as the selection of negated signals.


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