Introduction

This chapter provides an overview of the capabilities of the i.LON 600 and the terminology used in this document.

i.LON 600 User’s Guide

Introduction

The i.LON 600 LONWORKS/IP Server is a Layer 3 LonTalk® router that offers fast throughput for process control, building automation, utility, transportation, and telecommunications applications.

The i.LON 600 LONWORKS/IP Server improves on the performance of the i.LON 1000 with a new generation processor and package that provides reliable, secure Internet access to virtually any electrical device including lights, appliances, switches, thermostats, motors, meters, valves, HVAC, elevators, and security access products. The i.LON 600 lets you communicate with devices to monitor, adjust, and reconfigure them as needed.

The i.LON 600’s LonTalk router application allows IP to be used as a standard LONWORKS channel. Here, the term “router” is used to signify a LONWORKS router, not an IP router. From the LONWORKS perspective, the router application has all of the characteristics of a LONWORKS router with one side connected to a twisted pair LONWORKS channel and the other side connected to a LONWORKS/IP channel. The router application can be configured as any of the four standard LONWORKS router types: configured, learning, configured, bridge, or repeater.

The performance of the i.LON 600 is derived from a powerful 32-bit RISC processor and Echelon's LONWORKS/IP software architecture. The result is very high packet throughput in networks with large numbers of nodes and/or fast monitoring and display requirements.

The i.LON 600:

•Allows the millions of Internet-ready LONWORKS® devices to be monitored, controlled, or configured over the Internet.

•Transforms the Internet (or any IP-based LAN or WAN) into a pathway for carrying LONWORKS control information locally, nationally, or around the world.

•Includes MD5 authentication for secure access.

•Provides Layer 3 routing of LONWORKS control packets.

•Supports TCP/IP, UDP, DHCP, ICMP, SNTP, HTTP and FTP.

•Supports LONWORKS/IP channels with up to 256 devices.

•Supports multiple units behind NAT gateways/firewalls.

•Complies with EIA-852 & ANSI/EIA 709.1.

•Comes in 8TE DIN packaging.

•Available in a 24VAC/DC or 110/240 VAC power input.

•Is CE Mark, U.L. Listed, cUL Listed, TÜV Certified.

CAUTION

The high-voltage models (72601 and 72602) of the i.LON 600 are intended to be mounted inside of a suitable, safety-agency approved enclosure that is mounted in a restricted access area. High-voltage wiring must be performed only by a qualified service person.

The i.LON 600 mounts to a 35mm × 7.5mm or 35mm × 15mm DIN rail. The rear of the i.LON 600 enclosure contains a spring-loaded DIN rail lock, which securely attaches the DIN rail onto a permanent fixture. To release the enclosure from the DIN rail, insert a flathead screwdriver into the DIN rail locking tab and gently pull the tab down and away from the enclosure.

The following diagram shows the dimensions of the i.LON 600. All units are in millimeters:

Section 1: Setting Up and Using the i.LON 600 LONWORKS/IP Server

Wiring Connections

The i.LON 600 is available in two versions, depending on the type of LONWORKS channel you are using. Models 72601 and 72603 support the FT-10 free topology channel, while models 72602 and 72604 support the TP/XF-1250 channel.

The i.LON 600 has two rows of screw terminal wiring connections, an RJ-45 (Ethernet) data connection, and a DB-9 D-connector for connection to a console port. Figure 3 shows the locations of all i.LON 600 connectors.

Figure 3. i.LON 600 Server Data and Console Connections

Screw Terminal Connectors

The screw terminals are located on the top and bottom edges of the enclosure, and are numbered 1 to 4 (ascending from left to right) on the bottom, and from 5 to 6 (ascending from right to left) on the top.

The screw terminals accept 0.34 – 4.0mm2 (22 – 12AWG for the power connector and 16

– 26AWG for the LonTalk connector) gauge solid wire. The optimum tightening torque for the screw terminals is 9.217 kg/cm (8 lbs. in.) maximum. For the LonTalk connector, the optimum tightening torque is 6.913 kg/cm (6 lbs. in.). The ideal flathead screwdriver tip width is 3mm (0.12”). Wires should be stripped to a length of 7mm (0.28”). Although not required, it may be useful to use a soldering iron to tin the stripped lengths of any stranded wires to prevent fraying and inadvertent contact with adjacent terminals.

The screw terminal connections can be divided into two groups:

•Power

•LonTalk

8	Mounting, Cabling and Connections

Section 1: Setting Up and Using the i.LON 600 Internet Server

The RJ-45 10/100 BaseT Ethernet Port

The RJ-45 connector must be used with an RJ-45 male connector and a suitable Category 5 or Category 6 Ethernet cable connected to a 10BaseT or 100BaseT channel. The i.LON 600 automatically adjusts to the speed of the data port. If a 100BaseT network connection is established, the i.LON 600 illuminates the “100” LED indicator on the front panel. The i.LON 600 automatically detects whether it is connected to an Ethernet hub or directly to a computer and will switch the connection polarity as appropriate, so there is no need to use a crossover Ethernet cable.

The DB-9 Console Port

The i.LON 600 contains a console application that is accessed using a terminal emulation program, such as Windows HyperTerminal, via the EIA-232 DB-9 console port. This application allows you to set parameters such as the IP address, subnet mask, and FTP user name and password. The DB-9 is designed to be used with a DB-9 null-modem crossover cable with female connectors on both ends. Connect the cable to the i.LON 600 and an available COM port on a computer running the terminal emulation program. The connector pins on the DB-9 console are aligned as shown in Figure 4:

LONWORKS Network

The i.LON 600 is provided with one of two types of LONWORKS channels: TP/FT-10 free topology twisted pair (Models 72601 and 72603), or TP/XF-1250 (models 72602 and 72604). The twisted pair interfaces are polarity-insensitive and require connecting the twisted pair to terminals 5 and 6.

The screw terminals accept 0.34 – 4.0mm2 (22 – 12AWG) gauge solid wire. The optimum tightening torque for the screw terminals is 0.75mm (6 lbs. in.) maximum. The ideal flathead screwdriver tip width is 3mm (0.12”). Wires should be stripped to a length of 7mm (0.28”). Although not required, you should use a soldering iron to tin the stripped lengths of any stranded wires to prevent fraying and inadvertent contact with adjacent terminals

LONWORKS/IP Channels

Background & Definition

Traditionally, LONWORKS networks operate over dedicated network wiring such as twisted pair. A given segment of wiring is referred to as a channel. With the introduction of LNS 3.01 and the i.LON 1000 Internet Server (and now the i.LON 600 LONWORKS/IP Server), a new kind of channel has been created, the LONWORKS/IP channel.

16	LONWORKS/IP Channel Background & Definition

Section 1: Setting Up and Using the i.LON 600 Internet Server

Introduction to the LONWORKS/IP Channel

Unlike traditional LONWORKS channels that use a dedicated physical wire, a LONWORKS/IP channel uses a shared IP network, and is defined by a group of IP addresses. These addresses form a “virtual” wire. i.LON 600s and PCs running LNS (version 3.01 or better) use this virtual wire in the same way they use traditional dedicated twisted pair wiring.

The concept is similar to a Virtual Private Network (VPN). Each i.LON 600 in the system is aware of its peers and each i.LON 600 keeps peer information in its routing tables so it can forward “tunneled” LONWORKS packets to the correct IP address. Figure 9 shows a typical channel configuration.

The i.LON 600 routing engine is designed to deal with the potentially large latencies introduced by large IP networks such as the Internet. Without this intelligent routing engine, certain LONWORKS network services, such as the ability to detect duplicate packets, could be compromised.

Note that in Figure 9 or Figure 10, a PC running LNS 3.01, MIP, or other mechanism could be attached to any of the FT-10 channels.

PCs running LNS 3.01 incorporate the same routing intelligence as an

i.LON 600. Therefore, PCs running LNS version 3.01 or better can be directly connected as a member of the LonMaker/IP channel side of any i.LON 600. This allows topologies like the one shown in Figure 12:

A complete installation may contain many i.LON 600s and PCs – all sharing a LONWORKS/IP channel. Because the LONWORKS/IP channel can exist on any IP network, a system may now span the entire globe as easily as it once spanned a single building, as shown in Figure 13.

Note: A single LONWORKS/IP channel may contain up to 256 LONWORKS/IP devices. If your installation requires more than 256 LONWORKS/IP devices, you must create multiple LONWORKS/IP channels and bridge the IP channels using i.LON 600s (models 72602 or 72604) configured as repeaters.

IP Resources Required to Create LONWORKS/IP Channels

Before you install an i.LON 600 on an existing IP network, you will need to work closely with the IP network administrator to gather a list of the resources. You must also provide information about your i.LON 600 to the network administrator so they can adjust intervening firewalls to allow bi-directional communication with the outside world.

Information/Resources to be Acquired From the Network Administrator

To install one or more i.LON 600s on an existing IP network, you must obtain the following information and resources from the network administrator:

•IP Address (preferably static)

•Subnet Mask

•Default Gateway

•DNS Servers

•SNTP Server (optional, but recommended for high latency networks like WANs or the Internet)

In return, you must provide the network administrator with information about your i.LON 600s.

•Your i.LON 600s, by default, communicate on ports 1628 (UDP), and they respond to FTP and HTTP protocols. The Configuration Server, by default, uses port 1629 (UDP). See the TCP/IP Configuration section in this chapter for more information.

•Depending on your setup, your i.LON 600 may also contact an SNTP server (by default on port 123).

If the LONWORKS/IP channel spans a firewall or NAT router, it is important that these ports are open or forwarded to the i.LON 600. See Chapter 6 for more information.

The Internet Assigned Numbers Authority (IANA) defines default ports 1628 and 1629 for LONWORKS/IP channels. For more information, visit www.iana.org. You may also want to allow FTP and HTTP traffic to pass through your i.LON 600s.

Section 1: Setting Up and Using the i.LON 600 LONWORKS/IP Server

Use a table similar to the one below to plan your installation. The IP address of members within a LONWORKS/IP channel should be static. You can use IP addresses that are not static, but this requires additional configuration (see Appendix A). Addresses may be translated using Network Address Translation (NAT), though this also requires additional configuration.
