Multiple Controllers

Multiple controllers

Art-Net allows and supports multiple controllers on a network. When there are multiple controllers, Nodes will receive ArtPolls from different controllers which may contain conflicting diagnostics requirements. This is resolved as follows:

  • If any controller requests diagnostics, the node will send diagnostics. (ArtPoll->TalkToMe->2).
  • If there are multiple controllers requesting diagnostics, diagnostics shall be broadcast. (Ignore ArtPoll->TalkToMe->3).
  • The lowest minimum value of Priority shall be used. (Ignore ArtPoll->Priority).
