Matching devices
If you added devices to a Lon network while offline, you can go online, discover devices, and match them with their existing
database records. This copies discovered address data into the database record for the Lon device component. This procedure
works for both managed nodes (network nodes already configured with unique identifying information by an external Lon tool)
and unmanaged nodes (unconfigured network nodes, each of which may default to the same identifying information.)
Prerequisites: The device record(s) exists in the station database.
- Double-click the Lon network node in the Nav tree, and, if the Discovered pane is empty, click the Discover button.The system populates the Discovered pane with discovered devices.
This window has an available toggle in which you select whether to use the subnet-node address of the discovered (network) node, or have address management performed automatically by the Lon Device Manager.
- Select (highlight) a discovered device in the Discovered pane and its database record in the Database pane, click the drop-down control on the Match button and do one of the following:
- For a managed Lon network, click
Use Net Subnet/Node. - For an unmanaged Lon network, click
Use Db Subnet/Node.
This identifies which device to match with which database record. For managed networks it specifies to upload address data from the node. For unmanaged networks it specifies automatic assignment of subnet/node addresses. - For a managed Lon network, click
- Click the Match button.The system removes the device from the Discovered pane and leaves it selected in the Database pane.
- Right-click the device, select , and check all (recursive, transient, persistent).This configures the job to retrieve current configuration data from the device.
- Repeat this process for each device (previously-managed and previously-unmanaged).
- When all devices are matched, click the Learn Mode tool (
).This toggles out of learn mode.
- For managed networks, click to select (highlight) all the devices just matched, click the Quik Learn button, and click OK.
The system launches a learn links job, where it learns the Lon bindings for the devices from each device in the managed network. When complete, all devices should appear listed with a
Config Onlinestate, and with unique subnet/node addresses.
