Mark,

I put together a quick example for you of a way to get a variable pulse width output (I assumed that this is what you wanted):

With a combi time table of:

This gives the variable pulses:

Note that I chose "ConstantSegments" under smoothness and "HoldLastPoint" under extrapolation to make the table easier to construct.

My table entries are frequency in hertz (0.2 hz, followed by 0.4hz, 1hz, etc.) but you can change that easily to period if that helps your model. Attached is the model.

Regards,

Neil

I have pruned this down to its most basic example. Please see attached.

This shows the example where I want to vary the period of the Boolean pulse generator based on a parameter or variable. I did try changing the output of the table to a "variable" but that made no difference.

When I attempt to compile, it gives this error message:

I have used the Boolean pulse generator where I set the period to some parameter and that works as expected. The ability to dynamically change the period is what I have not been able to figure out.
