The Not function block logically inverts a discrete input signal and generates a discrete output value. When the input is True (1), the output is False (0). When the input is False, the output is True.
The block supports signal status propagation. There are no modes or alarm detection in the Not function block.
IN_D is the discrete input value and status.
OUT_D is the discrete output value and status.
The following figure shows the internal components of the Not function block:
