When I tried to wire two switches I can’t get them both to work on the same input, only one.  I tried every combo in all the posts I found.  How should pnp’s be wired so each can trip independently?

You may need have an "EXCLUSIVE-OR" IC on a PCB.

Or buy EX-OR Module to test first (see attached)

normaly your Limit Switches have three wires:
Brown -> 24v
blue -> 0V
black -> Output

so if you want two (NC) Switches in series you have to wire:

Switch 1
Brown -> 24v
blue -> 0V
black -> to Brown of Switch 1

Switch 2
Brown -> from black of Switch 1
blue -> 0V
black -> to input

He is using semiconductor (non-contact) sensors and not mechanical switches.
I do not think you can connect those electronic PNP sensors in series and in NC mode. I may be wrong.
