I used the #Px_CROSS_REF_0 successfully to link connectors in an interconnect to the schematic. In the schematic I used the #CROSS_REF also. Can someone clarify where and how I should use these?
#CROSS_REF is the normal way to use cross references. The software looks at if the symbol type is parent, child, or same level, and all of the different symbols for a single component reference each other in different ways depending on that type.
#Px_CROSS_REF_0 is used to cross reference specifically the symbol that uses the first pin of a component. #Px_CROSS_REF_1 would be the second pin of a component, and so on. These are used primarily to make connection labels for complicated parts. A connector with 50 pins that are scattered all throughout the schematic can have one of these connection labels made so you can generate easy to follow wiring diagrams.
The picture shows some part called SF2, and it is wired up normally. Then I threw a connection label on the page for an example. It shows each terminal of SF2, what wire is plugged into it, what component and terminal number that wire connects to, and a cross reference to where each terminal of SF2 shows up in the schematic, in case more information is needed.
Thanks Dan, excellent answer!
