Simulink - Triggered Subsystem - Initial Condition

Hi,

I can set the initial value of the output of a triggered subsystem. However, at step 2, the output is zero again as long as no trigger signal appears at the input. Is there a way to keep the value to the initial value until the first trigger occurs?

Thank you

This is the default behaviour usually. What is your trigger type?

Given just a default Triggered Subsystem block and a Step Input. I set the output port, "Out1", to have the "initial output" of 5.

The value of "Out1" stays 5 until the Triggered Subsystem block sees a rising edge.

This seems opposite from what you are seeing.

@ Chris: Rising Edge Trigger is what I am using. @ Ross: It is opposite to what I am seeing. My initial output disappears at time step 2, even though no trigger occurs.
