Hi Otto, This is just what I was wanting. Thank you! I was unfamiliar with the "pre" block and the triggered sampler and the combination of those does give me just what I want.

It would be nice if the functionality you provided in your example was a native part of the timer (suggestion for SystemModeler team).

Thanks again,

Mark

Hi Neil

Thank you for asking.

Ideally I want to have an element that monitors the time a state machine is in a particular state and when that state exits I would like a system variable that another block may read. The block in question is going to be a controller and the time is used by that controller.

By way of an example, a ramp slope converter could use the time for a current source to remove the charge from a sample-and-hold capacitor in order to know the voltage. It must know the time for that voltage to reach a known state.

I hope this makes sense.

Regards

Mark
