Timing diagram
Functional description
A 0 to 1 signal transition at input Trg sets output Q. The next 1 to 0 transition at Trg
retriggers the current time T
a
, and output Q remains set.
LOGO! resets output Q when T
a
= T. You can output a warning signal before the off-delay
time (T - T
!
) expires to reset Q for the time of the pre-warning period T
!L
.
A further one-shot at input Trg during T
a
retriggers the time T
a
.
If the block is retentive, LOGO! resets output Q and the expired time to the values before a
power failure; if the block is not retentive, LOGO! resets output Q and the expired time to
defaults after a power failure.

Note the defaults specified in topic Time response (Page 128).
Note
All times must have the same timebase.
