[kepler-users] Kepler-users Digest, Vol 90, Issue 10

Thu Nov 15 06:24:43 PST 2012

Alvin,

One simple way to get your desired results is to use the PN director.
You'll need to control the number of firings by setting the
firingCountLimit in your constant (array) actor.
I've attached an example.

Good luck!

Jon
