9.4.5.2. MONOSTABLE_B
Using this operator an output of "1" (TRUE) is generated by the rising/
falling edge on the input. This state is retained for the time t set.
Parameter
Time: The delay can be set to a value between 10 ms and 1098.3 s.
Rising Edge: If selected, the output is set to "1" (TRUE) by a rising
edge on the input signal and remains in this state for the time set.

If not selected, the logic is reversed, i.e. the output is set to "0" (FALSE) by a falling edge on the input signal and remains
in this state for the time set.

Unlike the MONOSTABLE operator, the OUT output on the MONOSTABLE_B is not retained beyond the maximum time t
set at "1" (TRUE).
Retriggerable: If selected, the time is reset on each status change on the input.
