Issue
Communications with other Lon network devices are lost after the IC-Lon/IC3-Lon has cold-started.
Product Line
Satchwell Sigma
Environment
Sigma
IC-Lon Integration controllers
IC3-Lon Integration controllers
Cause
The controller has been cold-started either manually or through the automatic process.
Resolution
The final part of the engineering process of the IC-Lon/IC3-Lon, is for the file named NVConfig.bin to be uploaded from the IC-Lon/IC3-Lon to the Sigma server. If this file is not uploaded, then the IC-Lon/IC3-Lon reverts to its non-bound state.
The NVConfig.bin file contains information about the Lon bindings and is modified during the binding process when using LonMaker.
To upload the NVConfig.bin, carry out the following:
- Open "System Diagnostics" on the Sigma server.
- Select the correct controller number.
- From the "Options" menu select "Upload Files" and NVConfig.bin
This file will now be uploaded and overwrite the existing file in the controller folder, and therefore when the controller next cold-starts, the correct file will be downloaded to it.

The Sigma system is now out of its support period, consideration should be given to transitioning or upgrading to
SpaceLogic - EcoStruxure Building Operation.
