The major difference between L ON W ORKS connections and Web connections is that L ON W ORKS
connections propagate data point updates over a L ON W ORKS channel via the LonTalk Protocol or the
LonTalk protocol tunneled through an IP-852 channel. Web connections propagate data point updates
via SOAP/HTTP over a TCP/IP network. Web connections provide an alternative solution to
L
ON W ORKS connections over an IP-852 channel for connecting devices over multiple networks;
however, Web connections are much slower (40 data point updates per second) than L ON W ORKS IP-
852 connections (1,000 updates per second).
To integrate your FPM applications with external devices stored in an LNS network database, you can
you can use L
ON W ORKS connections, which you can create with the LNS tree or an LNS application
such as the LonMaker tool. Alternatively, you can copy the data points from the LNS tree to the
SmartServer tree via the LNS Proxy Web service and then create Web connections between the data
points from the SmartServer tree.
Creating L
ON
W
ORKS
Connections
You can connect the data points in your FPM application using L ON W ORKS connections. You can
create L ON W ORKS connections using the LNS tree in the SmartServer Web interface (via the LNS
Proxy Web service) or using an LNS application such as the LonMaker tool. You can create two types
of L
ON W ORKS connections:
• Output data points on the SmartServer or external devices (the source data points) to the input data
points declared in the FPM application (the target data points).
• Output data points declared in the FPM application (the source data points) to the input data points
on the SmartServer, input data points in another FPM application, or the input data points on
external devices connected to the SmartServer (the target data points).
Note: If you are using the SmartServer in Standalone mode or your FPM devices are using the v40
XIF, you cannot create L
ON W ORKS connections with the LonMaker tool. In this case, you can create
Web connections from the SmartServer tree to connect the data points in your FPM applications. See
the next section, Creating Web Connections, for how to do this.
Connecting FPM Data Points with the LNS Tree
You can create L ON W ORKS connections with the data points declared in your FPM application from
the LNS tree. To do this, follow these steps:
1. Verify that you have completed the following steps:
a. Installed EES 2.0 and LNS Server Service Pack 5 on the i.LON SmartServer 2.0 DVD or the
i.LON SmartServer 2.0 Programming Tools DVD.
b. Added an LNS Server to the LAN.
c. Configured the SmartServer to use LNS network management services (LNS Auto or LNS
Manual) and synchronized the SmartServer to an LNS network database.
See Using LNS Network Management Services earlier in this chapter for how to do complete these
steps.
2. Verify that you have commissioned the FPM device using the SmartServer or an LNS application
such as the LonMaker tool. See Commissioning FPM Devices earlier in this chapter for how to do
this.
3. From the LNS tree in the left frame of the SmartServer Web interface, expand the LNS Server,
LNS network database, channel, device, and functional block containing the hub (source) network
variable.
4. Right-click a hub (source) network variable and then click Add Binding in the shortcut menu.
