How to change block sample time using a trigger

Could someone point me in the direction of which block I need to to use?

I have my Simulink model running at a fixed TimeStep of 0.001s. I have successfully created a TCP link using the TCP Client and TCP Send blocks. I do not want to pass the data to the TCP Send block every 0.001s, I only want to the pass the data to the TCP Send block when there is a trigger signal. The attached image shows what I would like to do:

I have tried the enabled/triggered subsystems but the output sample rate is the same as the input sample rate, i.e. 0.001s. For information, I am using Real-Time Simulation.

Is there any Simulink block that will change the output sample rate based on a trigger?

Hi Thomas,

I would simply move the TCP Send block inside of the triggered / enabled subsystem, this should do the trick :)

Best,

Thanks, that worked perfectly :)
