The Powerline adapter is just creating the low level physical connection (at layer 2 on the OSI model). All Powerline adapters will see all others if the electrical circuitry allows them to. Powerlines use the HomePlug standard which means you can connect up to 64 devices together at your home and they act line a big network switch. To do what you want, you'd need the Homeplug standard to support VLANs, which they don't currently.

many thanks.I have just come across this the FAQ on Powerline adapters which confirms taht you can have separate Powerline networks on a domestic power circuit pointing to useful guidenec on setting up.

Hi - the link didn't come up.

I'd be interested to see what information you have as I've never been able to do this without using equipment external to the Powerlines i.e. managed switches that support VLAN tagging or something similar (extra cost).

I am having difficulty copying links onto this webmail. This one was www.tp-link.com/uk/support/faq406 and there is a helpful one about set up of separate networks on https://weakwifisolutions.com.
