How to connect components signal in one to one interface

Hello everyone,
Does anyone know how to use one to one interface to connect components signal?
I don’t know what the connection principle is?
Thanks in advance!

You find it in help file:

In eCat you can find examples in Pick-And-Place-Library, “PickAndPlace Controller” and “PickAndPlace Double Sensor Conveyor”

It’s helpful to me.
Thank you very much!
