Issue

Erroneous subnet/node ID mismatch warning on a LonWorks unit in the System Plug-in

Environment

  • System Plug-In
  • LonWorks Device

Cause

Subnet and node IDs have gotten mixed up in the Vista database and must be recreated from LNS. The error appears as subnet/node address mismatch in the system plug-in.

Resolution

  1. In the System Plug-in, on the TAC Network side, find the LonWorks unit(s) that are generating this message
  2. Taking note what LonWorks group they are a part of
  3. Delete the LonWorks units.
  4. Update the TAC network. 
  5. The previously deleted controllers will be added back into a newly created group. Move the controllers out of this new group to the correct, desired group.
  6. Delete the empty group and update Vista.
  7. The mismatch error message should not be displayed any more.
