    Andover Continuum to AX

    I have a school that has Andover Native BACnet controllers in 17 of the new classrooms. We just took over the rest of the school, ver. AX 3.6.31 and I am trying to talk to these controllers to allow the owner to view the whole building from one graphic. I found all the devices after numerous discover, they can in a few at a time. When I went to discover the proxy points it took 20 min. but they did come in. Problem is they are all stale or in fault. This is the repeating error I am receiving.

    I have done a few integrations but never to Andover and I have never seen these errors.
    Any ideas?

    I'm not 100% sure on this, but it may be a BACnet routing issue due to duplicate network numbers? It's been a while but I had the same error a while back with some other controllers if I'm remembering correctly.
