During >= '0.0s
During is in two parts [t1:t2]. With t1 of During a positive value (say 5.0s) and
t2= 'Rising edge', the logic switch becomes True (for the period specified in
'Duration') 5 seconds after the 'Trigger On condition' transitions from False to
True. Any additional 'spikes' during the t1 period are ignored.
Falling edge option
During = '0.0s'
During is in two parts [t1:t2]. With During t1=0.0s and t2= '---' (Falling edge),
the logic switch becomes True (for the period specified in 'Duration') the instant
the 'Trigger On condition' transitions from True to False.
During >= '0.0s
During is in two parts [t1:t2]. With t1 of During a positive value (say 3.0s) and
t2= '---' (Falling Edge), the logic switch becomes True (for the period specified
in 'Duration') when the 'Trigger On condition' transitions from True to False,
having been True for at least 3 seconds.

During is in two parts [t1:t2]; if values are entered for both t1 and t2, then a pulse
