Once started, you use the Lon Device Manager to discover, add, and upload Lon devices, examine nvs and ncis as Lon components, and even perform writes and perform other
tasks (make bindings between devices, commission devices, etc.).
Figure 2. Lonworks Service tool in
Workbench
CAUTION: Any configuration you perform is not stored (persisted) in a station database, as this is station-less access (modeled completely
in RAM). When you close
Workbench, all modeling is lost—consider the Lonworks Service like a hand held device in this respect. 
For this reason, do not use
this tool to access a Lonworks network already managed by a station, but instead open that station, and access itsLonNetwork component.
