Description

One event is generated Delay after an event enters the unique input event port. Block may also generate an initial output event. The event date of that block is computed by the formula :

$$\begin{eqnarray} t_{i}&=&t_{\rm {init}} + i * T_{\rm {delay}}, \end{eqnarray}$$

where t_init the date of initial output event, T_delay the delay and i and internal integer discrete counter.

Dialog box

• Delay
  scalar. Time delay between input and output event.
  Properties : Type 'vec' of size 1

• Date of initial output event
  scalar. If Auto-exec>=0 block initially generates an output event at dateAuto-exec.
  Properties : Type 'vec' of size 1
