The Or function block generates a discrete output value based on the logical OR of two to sixteen discrete inputs. When one or more of the inputs is True (1), the output is set to True.
The block supports signal status propagation. There are no modes or alarm detection in the Or function block.
IN_D1 through IN_D[n] are the discrete input values and statuses (as many as 16 inputs).
OUT_D is the discrete output value and status.
The following figure shows the internal components of the Or function block:
