LON is supported for SmartServer Pi 4.3 and higher, with the exception of LON PL.

For LON devices, the SmartServer provides two network management modes called LON Device Management Mode (DMM) and LON Independent Management Mode (IMM). In LON DMM, the SmartServer manages the configuration of all LON devices provisioned by the SmartServer. In LON IMM, the SmartServer acts as an independent device in the LON network, and you must provide a network management tool such as the IzoT Commissioning Tool (CT) to manage the network configuration of the LON devices. DMM is the default setting where the SmartServer manages the LON devices in the network. When operating in DMM, all the internal LON routers in the SmartServer are configured by the SmartServer and function as repeaters. In IMM, the SmartServer does not configure its internal routers and they must be configured with the independent network management tool.

If you will be using your SmartServer on a LON network managed by another network manager such as the IzoT Net Server or LNS Server, or if you will be using your SmartServer solely as an IP-852 router or an LNS Remote Network Interface (RNI), switch to LON Independent Management Mode (IMM) as described on this page. Example network management tools include the IzoT CT and LonMaker tool.

Switching LON Management Mode

To set the LON management mode, perform the following steps:

1. If you defined any LON device interfaces or LON devices prior to switching from LON management mode, delete the interface and device definitions as described in Provisioning, Deprovisioning, and Replacing Devices or delete all definitions as described in Resetting the SmartServer IoT to Factory Defaults.
   
   
2. Open the Devices widget.
   
   
   
   
3. Click the SEGMENT CONTROLLERS tab.
   
   
   
   
4. Click the Action button () and select the Switch to LON Device Management Mode or Switch to LON Independent Management Mode action as appropriate for your system.
   
   
   
   The CMS dashboard displays the LON management mode as well as a message indicating that the LON mode change occurred.
