The And function block generates a discrete output value based on the logical AND of two to sixteen discrete inputs. The block supports signal status propagation. There are no modes or alarm detection in the And 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 And function block:
