Functional description
The 0 to 1 signal transition at input Trg triggers the current time T
a
. LOGO! sets output Q
when T
a
= T. A further signal at input Trg does not influence the time T
a
.
LOGO! resets the output and the time T
a
with the next 1 signal at input R.
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.
