Yes!

Thank you to the both of you, exactly what I was looking for.

Yes, you can only have character logistic slots if you have a character. If you create a character and attach your player to it, the slots will show up.

/c game.local_player.character=game.local_player.surface.create_entity{name="player", position={0,0}, force="player"}

Excellent! Thank you ...

Hello, I have researched all the way to Character Logistic Slots 4, but I don't have any character logistic slots. Is it because I am in sandbox mode? Is there any way to fix this?
