question

Milo,

the way you ask your question shows, that you still need to gain some basic understanding about how FlexSim works. I suggest to go through the Basic Tutorials in FlexSim´s User Manual and after take a look at the general functionality for the SendToPort field in the Output panel and the Separator object to see, how it behaves:

https://docs.flexsim.com/en/23.0/Reference/3DObjects/FixedResources/Separator/Separator.html

With this information you should easily be able to figure it out by yourself.
