Description
Enable parameter, see section Often used parameters
(Page 252).
When there is an edge change 0 → 1 the time of On
delay is started.
With the setting "True" the trigger is always active.
With the setting "False" the block is never processed.
When there is an edge change 0 → 1 at the "Reset" input
after the On delay ( = 1) has elapsed the output is reset
to 0.
With the setting "True" the input is always active and the
output is set to 0 immediately. The function is therefore
actually turned off.
With the setting "False" the input is never active.
On delay in milliseconds
After the time of the On delay has elapsed, the output is
set to 1.
