Xenta programmable in SmartStruxure: Application Download Failure


Downloading a Xenta Programmable controller under a SmartStruxure Automation Server LON channel fails with message: "Application Download Failure."

Viewing error details, the Progress view window shows "Wrong device version."

Product Line

EcoStruxure Building Operation


  • Automation Server LON channel
  • Xenta Programmable Controllers


Right click on the Xenta controller in StruxureWare Building Operation Workstation. Go to the Xenta tab. Check the Software version. If this is below 3.6, then the controller's .MOT file is out of date and must be updated.


The controller's software version must be at least 3.6 to be compatible with SmartStruxure.

Use the Download Wizard to load an updated .MOT file into the controller. See Download an .MOT file into a Xenta Programmable controller for further instructions.
