delay
xod/core/delay
Delays triggering of an incoming pulse by specified time
delay
@/delay
Delays triggering of an incoming pulse by specified time
Tnumber
Time to delay in seconds
SETpulse
Resets current countdown, starts new countdown
RSTpulse
Resets current countdown, i.e. cancels the delay
ACTboolean
Outputs true when delay is in progress
DONEpulse
Pulses once the delay is over
