Polling External Network Variables
You can use the SmartServer Web interface to copy the network variables of external devices managed
with OpenLNS CT, OpenLNS tree, or another OpenLNS application (formerly referred to as NVEs) to
the SmartServer. The SmartServer’s internal data server will then poll the external data point at the
rate specified in the data point’s Setup – LON Data Point Driver Web page. You can then add the
data points to the SmartServer’s built-in applications and to your custom SmartServer Web pages.
To copy network variables from OpenLNS CT to the SmartServer and set their poll rates, follow these
steps:
1. Verify that you have installed the Echelon i.LON Enterprise Services from the SmartServer 2.2
DVD. See Installing Echelon i.LON Enterprise Services in Chapter 2 for more information on
how to do this.
2. Verify that you have added an OpenLNS Server to the LAN that contains the OpenLNS network
database in which the network variable or configuration property is stored. See Adding an
OpenLNS Server to the LAN in Chapter 3 for more information on how to do this.
3. Verify that you have synchronized the target SmartServer with the OpenLNS network database
containing the external network variables or configuration property you are copying. See
Synchronizing the SmartServer to an OpenLNS network database in Chapter 5 for more
information on how to do this.
4. Expand the LNS Server icon, and then, if prompted, enter the User Name and Password for
logging in to the OpenLNS Server via the Echelon Enterprise Services 2.2. You initially specified
the user name and password in the Echelon Enterprise Services 2.2 installer. If you forgot the user
name and password, you can right-click the Echelon Enterprise Services 2.2 tray icon in the
notification area of your computer, and then click Options on the shortcut menu..
5. In the OpenLNS tree, expand the OpenLNS network database, channel, device, and functional
block containing the network variable to be copied to the local SmartServer, right-click the
network variable, and then select Create External NV on the shortcut menu. To copy multiple
