How can input port be open only when queue is empty ?

[ FlexSim 24.0.0 ]

Hello,

I can't seem to find a solution for opening the input port from the source to the first queue only when the queue is empty. I have set the trigger on the queue exit port to close the input port and that's how it should be, but I would still like to set the input port to open when all items are taken from the queue.

Please Help

Getting the timing right for opening/closing ports can sometimes be a bit finicky. If you use the Entry/Exit trigger, a 0s delay (by sending a message and only closing/opening the port in the message trigger) can often help.
