64 Using the LNS Proxy Web Service
Automatically Synchronizing the SmartServer to an LNS Network Database
You can synchronize the SmartServer to an LNS network database using LNS Auto mode. In LNS
Auto mode, the SmartServer independently initiates communication with an LNS network database
via the LNS Proxy Web service, and automatically sends network configuration changes made in the
SmartServer tree to the LNS network database. This mode requires the port on the LNS Server
computer selected for the LNS Proxy Web service (port 80 by default) to also be opened on any
firewalls blocking the SmartServer’s access to the LNS Server computer. The following graphic
illustrates how the SmartServer communicates with the LNS network databases in LNS Auto mode.
If you are using LNS Auto mode and other LNS clients make changes to the LNS network database
that are not propagated to the SmartServer over the LonTalk channel, network objects in the
SmartServer tree may lose synchronization with the LNS network database. In this case, you need to
manually synchronize the SmartServer as described in the next section, Manually Synchronizing the
SmartServer to an LNS Network Database.
To use LNS Auto mode to automatically synchronize the SmartServer to an LNS network database,
follow these steps:
1. Verify that the SmartServer is connected to both the TCP/IP network and the L ON W ORKS network.
2. Commission the SmartServer with the LonMaker tool, LNS tree, or another LNS application. For
more information on installing the SmartServer, see Installing the SmartServer with the LonMaker
Tool in Chapter 12 of the i.LON SmartServer 2.0 User’s Guide.
a. Verify that EES 2.0 and LNS Server Service Pack 5 have been installed on your computer.
See Installing EES 2.0 and Installing LNS Server Service Pack 5 in Chapter 2 for how to
perform these installations.
b. Verify that you have added an LNS Server (running LNS Turbo Server [version 3.25] or
newer) to the LAN that contains the LNS network database in which the network variable or
configuration property is stored. See Using the LNS Proxy Web Service earlier in this chapter
for how to do this.
3. Click Driver at the top of the navigation pane on the left side of the SmartServer Web interface,
and then click the Net network near the top of the SmartServer tree.
4. The Setup - LON Network Driver Web page opens.
