Preface

You can use an IP-852 channel to implement a LONWORKS® control network over an IP

network, and you can use an IP-852 channel to integrate multiple native L

networks into one large network that uses a high-speed IP-852 channel as a backbone.

With an IP-852 channel, you can use a single LNS

the networks attached to the IP-852 channel remotely and use L

bind the devices on the networks together, regardless of the distance between the

networks. You just need to attach your IP-852 devices, LNS Server computer, and the

computer running the LNS application to the same IP-852 channel.

configuration of the IP-852 devices on the IP-852 channel.

You can install the Echelon IP-852 Configuration Server on any computer with IP
connectivity to the IP-852 devices to be configured. The IP-852 Configuration Server is
available as a free download from

Introduction

This chapter provides an introduction to IP-852 channels, and describes the devices you

can use to create and manage these channels.

IP-852 Channel User’s Guide 1

Introduction to the IP-852 Channel

An IP-852 channel carries ISO/IEC 14908-1 packets enveloped in ISO/IEC 14908-4
packets. Unlike traditional L
create connections between the devices on the channel, an IP-852 channel uses a shared
IP network to connect IP-852 devices and is defined by a group of IP addresses. These IP
addresses form a channel that connects IP-852 devices on a shared control network so
they can communicate with each other. IP-852 devices include the SmartServer Energy
Manager, i.LON 100 Internet Server, i.LON 600 L
computers, and LonMaker
with the L

ONMARK IP-852 channel definition can also be used as IP-852 devices. For

systems using an LNS server, an IP-852 channel enables an LNS remote full client to
connect directly to a L

ONWORKS network and perform monitoring and control tasks.

The concept of an IP-852 channel is similar to a Virtual Private Network (VPN). Each
IP-852 device in the system is aware of its peers and each IP-852 device keeps peer
information in its routing tables so it can forward L
address or addresses.

Figure 1.1 shows a typical channel configuration in which three SmartServers are used
to create an IP-852 channel connecting three TP/FT-10 channels, each of which contains
the devices installed on a different floor in a building. The circled portion of the diagram
represents the IP-852 channel connecting the three SmartServers. As a result of this
connection, a single application can connect to devices on all three of the TP/FT-10
channels in the building, and monitor and control the entire building.

Figure 1.1 shows the IP-852 Configuration Server inside the IP-852 channel. The IP-852
Configuration Server stores the configuration of the IP-852 channel, including the IP
addresses of all the devices and routers installed on the channel. You will initially
configure the IP-852 channel with the IP-852 Configuration Server, and the IP-852

2 Introduction

Configuration Server must be running anytime you modify the configuration of the
devices on the IP-852 channel. You can run the IP-852 Configuration Server on any
computer with access to the IP network containing the IP-852 channel. Chapters 2 and 3
of this document describe how to use the IP-852 Configuration Server. The IP-852
Configuration Server is available as a free download from

www.echelon.com/ilon, and a

version of the IP-852 Configuration Server is also included with many products including

®

Echelon’s SmartServer, i.LON, LonMaker

, and LNS products.

The IP-852 channel definition accounts for the potentially large latencies introduced by
large IP networks such as the Internet. This enables key control network services such
as duplicate packet detection to function correctly over a high-latency IP network.

A complete installation may contain many IP-852 devices and computers—all sharing a
single IP-852 channel. Because the IP-852 channel can exist on any IP network, a system
may span the entire globe as easily as it spans a single building, as shown in Figure 1.2.

Figure 1.2 Large L

ONWORKS Network using an IP-852 Channel

Note: A single IP-852 channel may contain up to 256 IP-852 devices. If your installation
requires more than 256 IP-852 devices, you must create multiple IP-852 channels.

Creating an IP-852 Channel

This chapter describes how to create an IP-852 channel with the Echelon IP-852

Configuration Server.

IP-852 Channel User’s Guide 5

Creating an IP-852 Channel

You can create an IP-852 channel by configuring the IP-852 devices that are to be
attached to the IP-852 channel, and entering information about each IP-852 device in the
IP-852 Configuration Server.

This section describes how create an IP-852 channel using an example network with two
devices on an IP backbone to illustrate the process. In Figure 2.1, a L
channel 1 is bound to a device on channel 2 across an IP-852 backbone. The computer
running the IP-852 Configuration Server resides on the IP-852 channel, and has access
to both IP-852 devices through an IP connection. The computer running the LonMaker
software is connected to channel 1. To simplify the network, you can run the LonMaker
software and the IP-852 Configuration Server software on a single computer.

ONWORKS device on

Figure 2.1 Setting Up an IP-852 Channel

To create a network like the one illustrated in Figure 2.1, follow the steps below:

1. If you do not already have an Echelon IP-852 Configuration Server installed on a

computer with access to the IP network, download it from
and install the IP-852 Configuration Server as described in the ReadMe document
that accompanies the download.

2. Set the IP address, subnet mask, and default gateway for all the IP-852 devices you

plan to use on the channel. In Figure 2.1, the two IP-852 devices are SmartServers,
although your network could contain any IP-852 devices. Consult the documentation
for your IP-852 device for instructions on how to perform this step.

3. Start the Echelon IP-852 Configuration Server application. To do this, click Start,

point to Programs, point to Echelon IP-852 Configuration Server, and then
select IP-852 Configuration Server. The IP-852 Configuration Server main dialog
opens.

4. Verify that the IP-852 Configuration Server is attached to your IP network. The

Network status box should indicate Enabled. If it does not, select Enabled from
the Network menu. The IP-852 Configuration Server should correctly detect and
display the IP address of your computer in the Channel Description window.

To verify the IP-852 Configuration Server computer’s IP address, click Network and
then click Settings. The Network Settings dialog opens. Confirm that the IP
address of the IP-852 Configuration Server is shown in the IP Address or Host
Name property as shown in Figure 2.3.

IP-852 Channel User’s Guide 7

Figure 2.3 IP-852 Configuration Server Network Settings

5. If your computer has more than one IP address assigned to it, you can click Local IP

and specify the IP address to be used by the IP-852 Configuration Server.

6. The defaults for the channel properties will work in cases where network delays are

low. If you anticipate large delays in the IP segment (many routers / hops, or slow
media segments), you can adjust the channel property settings and/or use SNTP time
servers to synchronize IP-852 Router member devices. See Chapter 3 for more
information on this.

7. To configure the channel mode, right-click the New Channel entry and select

Properties from the shortcut menu. Select Backward Compatible, Standard
EIA-852 or Extended Firewall Support mode. See the

Channel Mode section in

Chapter 3 for more detailed information on these settings.

8. From the IP-852 Configuration Server main dialog, right-click the new channel, and

select New Device from the shortcut menu. An icon representing an IP-852 device
is added to the channel.

9. Right-click on the new device and select Rename Device from the shortcut menu to

enter a name for the device.

10. Right-click the device and select Device Properties. The device properties dialog

opens.

11. Enter the IP address of the IP-852 device and click Apply. This is the same address

that you assigned to the IP-852 device using the setup Web pages.

If you use a host name, it must be registered in a DNS server that is available to the
IP-852 Configuration Server computer.

12. Click the SNTP tab, and then select the Use Channel Default check box.

13. Click the Protocol tab, and then select the Use Channel Default check box.
