Closing and Opening a processor input depending on a queue's size

Hello,

I've modified an example posted in another forum that has a similar purpose. The only difference is that I am using a processor in place of a transporter

https://answers.flexsim.com/questions/43479/refill-a-rack-or-queue-depending-its-level.html

Just to be clear, I want to close the input of the processor when the inventory increases to a certain value, and open that same input when inventory drops below a certain value, but my changes to the triggers don't seem to work. Do you have any idea as to how I can fix my issue?

Your "On Exit" trigger is currently opening "Processor1"'s input port every time an item exits the queue. I think if you change this trigger's logic, you will be able to control the inventory as you would like.

Close Input of Process.fsm


The example you provided does almost exactly what I want it to do. How could I close the input of the processor preceding the queue with that same trigger in the queue? Here is a model where I use some custom code to try and close the input of the processsor when the queue's inventory is above a certain value. I try to open that same input, but my code doesn't seem to have any effect.
