    Kai,

    If one of the RS-485 node is physically damaged, I don't think there is a good way to keep communication work until you get rid of the bad IC. You can prevent this from happening by applying better protection (higher ESD level/fault voltage IC, or more robust external components). It is also a challenge to nail down the bad node fast on a multi-node bus.

    Regards,
