"Field Unit Not Configured" error during download


"Field Unit Not Configured" error during download


  • Vista System Plug-In
  • Xenta programmable controllers 
  • Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B


If trying to download the application and parameters in a Xenta controller and the error "Field Unit Not Configured" is received, one cause that has been found is when an Xenta base unit is placed in a LonWorks group (even if it appears to be a part of a Xenta group).


  1. The group in question should be deleted from the Vista database pane in the Vista System Plug-In.
  2. Update the Vista database and the controllers imported into the Vista Database should be created in proper groups.
  3. Verify that the group is tagged correctly and then update the Vista database once more.
  4. Verify for the final time in Vista Workstation that the group is a Xenta group before downloading to the controller in the Vista System Plug-In.
  5. You may also drag that Xenta unit into an existing Xenta group after it has been re-imported.
