ACN /artnet failover

I always do it like that:

When Using ACN:
* Clone DP to the backup console
* Set the backup console to a lower priority on the ACN Outputs
* Done ;-)

When using Art-Net:
* Clone DP to the backup console
* Depending on the Art-net Node you are using, you can now give priorities to IPs or Universes. If IPs is possible you can send on the same subnet/universes, if only a priority is possible set the first DP eg. to send on subnet 0 and the backup DP to send on subnet 1. Set your Artnet Node to these settings.

if your art-net node not supporting priorities you simply can use kind of backup-switch (e.g. rockswitch 4n)
