ZBuilder will not open on certain commissioned Xenta 121s in Lonmaker


ZBuilder will not open on certain commissioned Xenta 121s in Lonmaker. It will open on others in the same network.


  • ZBuilder
  • LonMaker


Incorrect or corrupted configuration parameters prevent the ZBuilder plug-in from opening on specific Xenta 121s.


  1. Right-click on the device in LonMaker and choose Browse
  2. Take a screen capture of the various settings that will need to be re-entered
  3. Re-commission the Xenta 121 controller with default values (this will erase any configurations that have been made)
  4. ZBuilder will now work correctly.
  5. Re-enter any previously configured parameters
