Zero Devices Selected for Download


When trying to download application and parameters in the TAC Vista System Plug-In, the message in the Output pane says 0 device(s) selected for download. The download window in the system plug-in does not open.


  • Vista
  • NL220
  • LonMaker
  • System Plug-in


When the system plug-in displays zero devices selected for download, it is seeing the Xenta controller as a LonWorks device. There are a couple of possible causes for this issue.

  • The neuron ID set for this device may be wrong.
  • The correct device template was not browsed in when the node was created in NL220/LonMaker.


First check the neuron ID of the controller and verify that it is correct. If it is correct, follow these steps.

  1. In the System Plug-in, on the TAC Network side, select the Xenta controller that is not being recognized and delete it. Take note of which group the controller belonged too.
  2. Update the TAC network. 
  3. The previously deleted controller will be added back into a newly created group. Move the controller out of this new group to the correct, desired group.
  4. Delete the empty group and update Vista database.
  5. Now select the controller and download application and parameters.
