Simulate part frequencies with time

[Pablo Muñoz]

 Hello everyone, I've only been using jaamsim for a short time. I've encountered a problem that I don't know how to simulate. In a process, we have a machine that, depending on the number of parts produced, needs to be stopped and a tool replaced, and this operation is performed periodically. I've tried doing this with a DowntimeEntity, but it always relates downtime to frequency (time). However, this distorts the model when simulating by modifying other variables. How could I simulate it?
Thank you very much for the help.
