1. Overview

1.1. Introduction

The eNodeIV, Grouter4 (GR4) router supports two open standard protocols, namely ANSI/EIA

709.1 and ANSI/EIA 852. Both the ANSI/EIA 709.1 and ANSI/EIA 852 are defined by the

Consumer Electronics Association Technology & Standards R7.1 HCS1 Subcommittee. For more

details see http://ce.org/. For the sake of brevity the remainder of the document will refer to

the standards as 709.1 and 852. The 709.1 is also known by its trademarked name, LonTalk®. A

709.1 network is also commonly referred to as a Local Operating Network or LON. This

document will use 709.1 network and LON interchangeably.

The 852 protocol acts as the transport service to convey 709.1 messages over Internet Protocol

(IP) networks. This technique of using another protocol (i.e. 852) to transport a message over

an alternate media is often referred to as tunnelling. In 852 parlance the tunnelled protocol is a

Component Network (CN) protocol. The 852 protocol is a generic tunnelling protocol and is not

limited to 709.1. However, a particular implementation of the 852 protocol may only support

the tunnelling of a single CN protocol. The tunnelled CN messages have no information or

awareness of the tunnelling process. Although some of the figures in this document use CN or

CN/IP to represent a component network or component network to internet protocol

connection, the only CN currently supported by the eNodeIV device is 709.1

A component network protocol is often called a field bus due to its use for machine to machine

networking and control in the field. This document, however, will only use the term component

network or CN.

852 not only provides the vehicle to transport ANSI 709.1 messages across IP, but it also

provides management of these connections or routes. A logical grouping of 852 devices that

exchange packets is called an 852 channel. One may think of an 852 channel as a kind of virtual

LAN on an IP network.

An eNodeIV device forwards 709.1 packets to or from an IP channel (using an Ethernet or WiFi

transceiver) and a CN channel (using twisted pair FT-10 or RS-485 transceivers). The eNodeIV

device has a presence on, or physical connection to, both channels. The router takes 709.1

messages from the component network, wraps them in an 852 packet and sends them over the

IP network. The eNodeIV device also receives 852 packets on its IP interface, un-wraps them

and puts the 709.1 messages on the CN channel. The virtual 852 channel looks like a CN channel

to CN nodes. The IP element is transparent. This enables a flat network and is more easily

managed and scaled than using CN to IP interfaces that do not hide the IP element from the CN

nodes. The important thing is not what the CN to IP device is called but how transparent it

makes the IP network appear to the CN nodes.

Network connection devices can operate at different layers of particular networks protocol

stack. 709.1 is an OSI 7 Layer type protocol. Whereas, the Internet Protocol has only 4 layers.

(See Figure 1.1 for a diagram of the different layers of the two protocols.)

September 2011 6 V1.44

Fig.1.1: Network Layers

A network connector is a device that joins different parts of a network. Connectors have a

specific name that is dependent on the layer at which the connector operates. For example a

router operates at the network layer and a gateway at the application layer. Because higher

layers of the protocol do not have access to some of the information stripped away by lower

layers, network connectors operating at different layers have different capabilities. There is also

some abuse of terminology so that the descriptions of network connectors from different

manufacturers may be confusing. For example, a repeating router may be called a repeater for

short. Although a repeating router acts similarly to a physical layer repeater, it operates at the

network layer and is not equivalent. It is usually best to find out at which layer a network

connector operates.

Fig.1.2: Network Connector Types and Associated Layers

September 2011 7 V1.44

The eNodeIV device is a more complex connector because is connects two different protocols

and also connects the protocols at different layers. On the IP side the eNodeIV device operates

at the application layer and so is appropriately called an IP Gateway. On the 709.1 side the

eNodeIV device operates at the network layer and is appropriately called a 709.1 router. So

depending on the user’s perspective the eNodeIV could be called a gateway or router or a

router/gateway. (See Figure 1.3)

Fig.1.3: CN to IP Router/Gateway Architecture

The eNodeIV device also employs a web server for configuration purposes. (See Figure 1.4)

Fig.1.4: eNodeIV Architecture

September 2011 8 V1.44

1.2. Configuration Parameters

The information required for successful ANSI/EIA 709.1 transport can be broken up into the

following two categories: device parameters and channel parameters.

Device parameters include information such as: IP address, IP port, Name, and Address of

configuration server.

A channel is a logical grouping of LON to IP routers. The minimum requirement for tunneling

ANSI/EIA 709.1 data is the use of two routers. Router A sends data to Router B and vise versa.

However, routers can also send data to more than one router. In such a case, Router A sends

data to Routers B, C, and D, which in turn send data back.

A channel, then, is defined as a group of routers that all send information to each other. The

lines of communication are open in both directions and to all members—a complete mesh of

connections.

Typically, channels are managed through the use of a configuration server (called Normal mode

see below). The configuration server informs all members in the channel about the channel

information, which includes the adding and removing of channel members. Configuration

servers are capable of managing multiple channels, while routers belong to only one channel at

a time.

Lon to IP routers can also be managed manually by configuring each device uniquely (called

Manual mode, see below). In such a manual configuration, for proper operation, devices must

have mutual membership in each other’s channel lists. That is if Device A is in Device B’s

channel list then Device B must be in Device A’s channel list. However if Device C is in Device B’s

channel list, Device C does not have to be in Device A’s channel list.

1.3. Modes of Operation

The eNodeIV device can operate in one of two modes: (1) Manual, (2) Normal.

1.3.1. Manual Mode

In Manual mode the user has control over the eNodeIV device's configuration only. The user

can change the eNodeIV device's operating information and determine to whom the router will

send information. In Manual mode the eNodeIV device will honour read requests from other

devices or configuration servers, but it will block requests to write or change internal

parameters. This is a more secure mode and may be preferred on open networks. This mode is

also preferable with non-standard configurations such as Flood Mode or DDNS.

1.3.2. Normal Mode

Normal mode allows the user to view configuration data and channel data set by a remote

configuration server such as an i.LON® configuration server. The configuration server sets some

September 2011 9 V1.44

of the operating parameters of the eNodeIV device. Configuration servers mostly manage the

device's channel. The channel is made up of other devices to which the eNodeIV device will

tunnel or send ANSI/EIA 709.1 data. In Normal mode the adding and deleting of devices is

managed exclusively by the assigned configuration server. The configuration server provides a

single interface to add and delete devices. Finally, Normal mode permits read access to

information by other devices and write access to information for the assigned configuration

server.

Note: Echelon’s LNS based VNI interface (LonMaker) only works in Normal mode. In order for a

eNodeIV device to communicate directly over an IP channel to a VNI interface requires that the

eNodeIV device be in Normal mode.

1.4. Applications of the eNodeIV Device

1.4.1. Multi-site building automation networks

The interfaces described here provide the management necessary for the ANSI/EIA 852 to

tunnel ANSI/EIA 709.1 packets successfully over IP. This ability provides wide area network

(WAN) support to ANSI/EIA 709.1 networks. This allows multi-building or multi-site connection

of automation networks.

Fig.1.5: Multi-site building automation network with internet connectivity

1.4.2. IP backbones for LON traffic aggregation

Furthermore, since the IP networks can support much higher traffic capacity, eNodeIV devices

can also be used to aggregate 709.1 traffic from several LON channels over one IP channel. The

ability to aggregate larger traffic volumes allows several eNodeIV devices and other 709.1 to IP

routers to be used as network backbones for 709.1 networks.

September 2011 10 V1.44

Fig.1.6: Example Hybrid Network

Fig.1.7: Example WiFi Ad Hoc Network

1.4.3. Roaming Connections

Finally, LON to IP gateways may be connected to specialised IP applications instead of to other

gateways. Connecting an IP application to a eNodeIV device provides these specialised

applications with roaming capabilities which would be difficult if these applications were

required to be directly connected to the 709.1 network e.g., LonMaker etc. An example of how

several eNodeIV devices can be interconnected to support an IP backbone for several LON

September 2011 11 V1.44

networks is show in Figures 1.6 and 1.7.

1.5. IP Addressing Modes

The eNodeIV device uses one of two forms of IP addressing: unicast and multicast. Multicast

currently only works when in manual mode.

The advantage of multicast is that for networks with multiple Gateways (especially in flood

mode), multicast may be more efficient. The disadvantage of multicast is that some internet

routers do not support it. Multicast mode can reduce the IP traffic relative to unicast when

there are a large number of 852 devices in the channel. Up to 255 devices per IP domain are

supported with multicast. Some older IP routers do not support multicast and therefore you

will not be able to route 852 packets across a unicast only router with multicast addressing. IP

router support for Multicast is not a concern when all the 852 devices share the same subnet.

The following figures illustrate the differences between multicast and unicast.

Fig.1.8: Unicast

Fig.1.9: Multicast

1.6. System Requirements and Connections

1.6.1. System Requirements

To configure the eNodeIV device, you will need a web browser such as Internet Explorer,

Mozilla, Safari, or Firefox.

The eNodeIV device will communicate with any of the following:

•GRouter4, eNodeIII, or eNode 852 router

•Echelon i.LONTM router or LNS VNI based tool such as LonMakerTM. The supported versions

of LonMaker are versions 3.1 or later including turbo version 3.2x. The supported versions of

LNS Server are versions 3.0x or later including 3.2x.

•Coactive Router-LL router

•Any 852-A, 852-B or later compliant node

To operate in normal mode an 852 configuration server is required such as the Echelon i.LON

Configuration Server (ILCS). Manual mode does not require a configuration server. The

supported version of the ILCS is version 2.x or later.

Note: The eNodeIV and Router-LL routers can interoperate in either Manual mode or with the

Router-LL configuration server.

The eNodeIV device also needs the following hardware:

•Cat 5 Ethernet Cable (for Ethernet versions).

•Regulated 5V DC power supply.

•Twisted pair cable for 709.1 (LON) port.

Up to date documentation is available at www.contol-network-solutions.co.uk

To find out what version of ILCS you are using, select the help>about menu. To find out what

version of LonMaker you are using, click on the icon in the upper left hand corner of the

window and select the about ... menu. This will also show the version of LNS Server. To see

what version of LNS server you are using when you don't have LonMaker, use the Windows

Control Panel, Add or Remove Programs, the Echelon LNS Server item, Click here for support

1.6.3. Wiring

The standard configuration for the eNodeIV4 has a 4 pin 5.0 mm spaced screw terminal block.

The pins from top to bottom are labelled A, B, (logic ground), and 5VDC. To use the terminal

block unscrew the terminal screws on the block and insert the ends of the appropriate wires

into each opening. Tighten the terminal screws. Pins A and B are the 709.1 LON channel port

September 2011 14 V1.44

pins. For FTT-10 transceivers, use the A and B pins. The pins are polarity insensitive. For

RS-485 transceivers use the A and B pins appropriately and insert the RS-485 ground lead into

the terminal block pin with the (ground) symbol next to the pin labelled A. There are two

power input pins labelled (logic ground) and 5VDC. The eNodeIV requires regulated 5 Volt DC

positive on the 5VDC pin. Attach the ground pin from the power supply to the pin labelled .

The power input is polarity sensitive but does have reverse polarity protection. If after

powering up the 5V input, the power LED does not light up, disconnect power and check the

polarity of the input power wires before recycling power. Applying a reverse voltage for an

extended time period may damage the eNodeIV.

2. Web Configuration

The Web-based eNodeIV device interface allows the user to access and change configuration

data on the eNodeIV device by using any http Web browser attached to the network. This

allows users to make changes to the eNodeIV device remotely. This chapter familiarises the

user with the various pages of the Web-based Interface and describes the steps necessary to

changing configuration data.

2.1. Default IP Configuration

The eNodeIV device is configured through a web browser such as FireFox, Internet Explorer,

Safari, or others. In order to connect to the eNodeIV device from a web browser, the eNodeIV

device and the computer running the web browser must be connected to the same IP network.

The factory default IP host address of the eNodeIV device is 10.0.2.40 with subnet mask of

255.255.255.0. The router's web server is serving http on port 80. The computer running the

web browser must be able to access the eNodeIV device's subnet.

Default Internet Configuration

IP Host Address 10.0.2.40

IP Subnet Mask

255.255.255.0

Web HTTP Port 80

2.1.1. Ethernet

For Ethernet equipped eNodeIV devices, first configure the host computer to add an IP

interface on subnet 10.0.2.0/255. Connect one end of a Cat5 Ethernet cable to the RJ-45 on

the eNodeIV device and the other end to an Ethernet hub or switch or directly to a computer

with a crossover cable or straight through if the computer’s Ethernet port supports auto

crossover (Auto MDIX). The eNodeIV Ethernet port is MDI only. In cases where the LAN does

not support the default subnet, a direct connection between the ENodeIV device and the web

browser host computer will be needed.

September 2011 16 V1.44

Fig.2.1: Ethernet setup with hub or switch

Fig.2.2: Ethernet with direct connect crossover cable

2.1.2. Wi-Fi (802.11b)

For WiFi equipped eNodeIV devices, an 802.11b WiFi access point or ad hoc connection must

be setup between the web browser host computer and the eNodeIV device. First configure the

host computer to add an IP interface on subnet 10.0.2.0/255. Instructions for setting up

Windows XP are in the next section. Then setup the WiFi configuration. The default WiFi

configuration for the ENodeIV device is as follows:

Wireless SSID: "Adept"

Wireless Mode: Any Type (Ad hoc or Infrastructure)

Channel: Search

Encryption: None

The access point or ad hoc connection must be set up to allow a connection on a network with

SSID of Adept or Any. There are many different topologies that may be employed for

connecting to the eNodeIV (eNodeIV) WiFi version. The following figures show some of the

more common ones.

Fig.2.6: WiFi setup with access point and WiFi card on PC

September 2011 18 V1.44

2.1.3. Wi-Fi Setup in Windows XP

•Go to the network connections control panel. Right click wireless connection and select

properties.

•Select the general tab. Set the IP address to one that is in the same subnet as the

eNodeIV’s default IP of 10.0.2.40 with a subnet mask of 255.255.255.0. For example you

could use 10.0.2.41.

•Go to network properties and select the connection tab. Select “manual connect” to an

available wireless network not automatically connect.

•In the main network connections control panel, create a new wireless network by selecting

"add new network". Use the following settings the network:

In the Association Tab set the following fields:

SSID: "Adept"

Network Auth: open

Data Encryption : Disabled

Check the "this is a computer to computer network (ad-hoc)” box.

In the Authentication Tab leave the settings at the defaults.

In the Connection Tab set the following:

Check the "connect when this network is in range” box.

•Click Ok, then Ok again to save the settings.

•After a minute or two the computer will automatically connect to the eNodeIV

•You can now access the eNodeIV's configuration web pages through a web browser using a

url of "http://10.0.2.40".

September 2011 19 V1.44

2.2. Establishing a Connection (Ethernet or WiFi)

Once the IP connection (WiFi or Ethernet) is setup, power up the eNodeIV device. It takes about

60 seconds for the eNodeIV device to boot up. On an Ethernet device Boot-up is completed

when the yellow link light flashes off once and then back on solid and the green traffic light

starts flashing.

On a WiFi device, boot-up has completed when the green traffic light starts flashing.

Depending on the type of connection, the yellow WiFi link light may or may not flash.

In infrastructure mode the yellow light is on solid.

In Ad Hoc mode is flashes 5 seconds on, and 1 second off.

If no connection, it flashes one second on, and one second off.

2.2.1. Ping to Verify

For either Ethernet of WiFi, to verify that the IP connection has been made send an IP ping to

the eNodeIV device at its default IP host address (10.0.2.40). In Linux, Windows 2k+, or Mac OS

X a ping can be sent from the command line as follows:

ping 10.0.2.40

Then type enter or return. This will ping 4 times.

ping -t 10.0.2.40

This will ping continuously until a break control-c is typed.

If there is no response, double check all network connections and cables and device setup.

Make sure you can ping out by pinging some other computer on your network. Once you can

successfully ping the eNodeIV device, establish a web connection from a web browser window

as follows:

http://10.0.2.40

Then type enter or return.

Note: Sometimes when configuring multiple routers in quick succession using the same

computer, IP communications will fail temporarily for the next router. The reason for this is that

the IP stack on the computer caches the MAC address of each device in an ARP table, indexed

to the IP address. The first router that responds on 10.0.2.40 will have its MAC address

associated with 10.0.2.40 in the ARP table. Because we ship every router with the same default

address, the first time each router is accessed it is on the same IP address. The next router that

uses 10.0.2.40 will have a different MAC address and when the computer tries to communicate

with it, the computer may use a stale cached MAC address instead. To clear the ARP table entry

for 10.0.2.40, in Windows, Linux, or OS X, enter on the command line (or DOS prompt):

arp -d 10.0.2.40

September 2011 20 V1.44

2.2.2. User Name and Password

The eNodeIV device web interface will prompt for a user name and password. The default user

name is CNS and the default password is eNode . The user name and password are case

sensitive so make sure to use a capital CNS and capital N respectively. Click OK. You will now be

shown the home or status page for the eNodeIV device web based Configuration Tool. To

navigate the various pages in the Tool, simply click the buttons on the left side of the page to

link to the appropriate page. The button corresponding to the page that is currently displayed

will be highlighted in pink. Each of the pages in the web based Configuration Tool will be

explained in the following sections.

Fig.2.7: User Name and Password Authentication

Once communications have been established, new IP or WiFi parameters may be entered. The

procedure is as follows:

•Set up IP and/or WiFi interface between host computer and eNodeIV device using default

network settings

•Reconfigure the eNodeIV device to use new network settings

•Reconfigure the IP and or WiFi network to use new settings

•Reboot eNodeIV device and re-establish communications using new settings

•If communications with new settings cannot be established because of lost or incorrect

settings then revert eNodeIV device to factory defaults and start over.

2.3. Restoring Factory Defaults

The web Tool allows customization of the IP address, net mask, WiFi SSID and security settings,

HTTP port, web user name, and password. Should any of these settings be forgotten or setup

incorrectly, communication with the eNodeIV device may not be possible. In this event, the IP

settings on the eNodeIV device can be restored to factory defaults so that a known set of IP,
