About This Document

This document describes preparation, operation and maintenance of the XYR 400E Ethernet Modem. Mounting, installation and wiring are covered in other documents.

Honeywell does not recommend using devices for critical control where there is a single point of failure or where single points of failure result in unsafe conditions. XYR3000 is targeted at open loop control, supervisory control, and controls that do not have environmental or safety consequences. As with any process control solution, the end-user must weigh the risks and benefits to determine if the products used are the right match for the application based on security, safety, and performance. Additionally, it is up to the end-user to ensure that the control strategy sheds to a safe operating condition if any crucial segment of the control solution fails.

Chapter One INTRODUCTION

The XYR 400E Industrial WiFi Wireless Ethernet module provides wireless connections between Ethernet devices or Ethernet wired networks (LAN’s). It complies with the IEEE 802.11b standard. The XYR 400E has an internal 2.4GHz direct sequence spread spectrum (DSSS) wireless transceiver, which can be used without a radio license in most countries. Users can select one of 11 x 5 MHz wide channels, with the first channel centred at 2.412 GHz.

Note that regulations in North America and part of Europe permit all 11 channels to be used in these countries. Please check with your HONEYWELL representative for the permitted channel usage in your country.

The XYR 400E unit also provides two serial connections as well as the Ethernet connections. It is possible to use all three data connections concurrently, allowing the XYR 400E to act as a Device Server. Wireless connections can be made between serial devices and Ethernet devices, however appropriate driver applications are required in the host devices to handle the different data format. The XYR 400E does provide connection functionality between serial “Modbus RTU” devices and Ethernet “Modbus TCP” devices.

The XYR 400E is available in two models with different RF power:

XYR 400E-100 100mW of RF power

XYR 400E-300 300mW of RF power

Note that European regulations do not permit more than 100mW of RF power to be used. In USA, Canada and Australia, up to 1W of RF power may be generated. In other countries, please check with your HONEYWELL representative.

The XYR 400E has a standard RJ45 Ethernet connection which will operate at up to 100Mbit/sec. The module will transmit the Ethernet messages on the wireless band at rates between 1 and 11 Mbit/sec.

1.1 Network Topology

The XYR 400E is an Ethernet device, and must be configured as part of an Ethernet network. Each XYR 400E must be configured as:



an “Access Point” or a “Client”, and



a “Bridge” or a “Router”.

You can also connect to the XYR 400E via a RS232 or RS485 serial port using serial server or PPP (point-to-point) protocol. PPP allows the XYR 400E to connect serial communications into the Ethernet network.

Access Point vs Client

The Access Point unit acts as the “wireless master” unit. The Access Point sets up the wireless links to the Client units, and controls the wireless communications. The first diagram shows two Ethernet devices being linked. One XYR 400E is configured as an Access Point and one as a Client - in this example it doesn’t mater which unit is the Access Point.

The second diagram shows an existing LAN being extended using XYR 400E’s. In this example, the Access Point should be configured at the LAN end

- although the wireless link will still work if the Client is at the LAN end.

Bridge vs Router

Each XYR 400E is configured with an IP address for the Ethernet side, and another for the wireless side.

A Bridge connects devices within the same Ethernet network - for example, extending an existing Ethernet LAN. For a Bridge, the IP address for

In the above example, the wireless link is part of LAN A, with the Client unit acting as a Router between LAN A and LAN B. Alternately, the Access Point could be configured as a Router - the wireless link is then part of LAN B.

If more than two routers are required within the same radio network, then routing rules may need to be configured (refer section “3.11 Routing Rules” for further details). There is no limit to the number of Bridges in the same network - although there is a limit of 128 Client units linked to any one Access Point.

1.2 Getting Started Quickly

Most applications for the XYR 400E require little configuration. The XYR 400E has many sophisticated features, however if you don’t require these features, this section will allow you to configure the units quickly.

First, read Section 2, “Installation”. The XYR 400E requires an antenna and a power supply.



Power the XYR 400E and make an Ethernet connection to your PC (for further information on how to do this, refer to section 3.4)



Set the XYR 400E address settings as per section 3.4



Save the configuration - the XYR 400E is now ready to use.

Before installing the XYR 400E, bench test the system. It is a lot easier to locate problems when the equipment is all together.

There are other configuration settings which may or may not improve the operation of the system. For details on these settings, refer to section 3.

Chapter Two INSTALLATION

2.1 General

The XYR 400E module is housed in an rugged aluminium case, suitable for DIN-rail mounting. Terminals will accept wires up to 2.5 sqmm (12 gauge) in size.

All connections to the module must be SELV. Normal 110-250V mains supply should not be connected to any terminal of the XYR 400E module. Refer to Section 2.3 Power Supply.

Before installing a new system, it is preferable to bench test the complete system. Configuration problems are easier to recognize when the system units are adjacent. Following installation, the most common problem is poor communications caused by incorrectly installed antennas, or radio

11 XYR400E Ethernet Modem Version 1 5/1/08

interference on the same channel, or the radio path being inadequate. If the radio path is a problem (i.e. path too long, or obstructions in the way), then higher performance antennas or a higher mounting point for the antenna may rectify the problem. Alternately, use an intermediate XYR 400E Module as a repeater.

The foldout sheet XYR 400E Installation Guide provides an installation drawing appropriate to most applications. Further information is detailed below.

Each XYR 400E module should be effectively earthed via the "GND" terminal on the XYR 400E module - this is to ensure that the surge protection circuits inside the XYR 400E module are effective.

2.2 Antenna Installation

The XYR 400E module will operate reliably over large distances. The distance which may be reliably achieved will vary with each application - depending on the type and location of antennas, the degree of radio interference, and obstructions (such as buildings or trees) to the radio path.

The maximum range achievable depends on the regulated RF power permitted in your country, and whether you use separate transmit and receive antennas. With a single antenna, 5 km (3 miles) can be achieved in USA, Canada and Australia (4W ERP) and 1km in Europe (100mW ERP). With separate transmit and receive antennas, more than 10km (6 miles) can be achieved in USA, Canada and Australia and more than 5 km in Europe.

To achieve the maximum transmission distance, the antennas should be raised above intermediate obstructions so the radio path is true “line of sight”. The modules will operate reliably with some obstruction of the radio path, although the reliable distance will be reduced. Obstructions which are close to either antenna will have more of a blocking affect than obstructions in the middle of the radio path. The XYR 400E modules provide a diagnostic feature which displays the radio signal strength of transmissions (refer Diagnostics section).

Line-of-sight paths are only necessary to obtain the maximum range. Obstructions will reduce the range, however may not prevent a reliable path. A larger amount of obstruction can be tolerated for shorter distances. For short distances, it is possible to mount the antennas inside buildings. An obstructed path requires testing to determine if the path will be reliable - refer the section 6 of this manual.

Where it is not possible to achieve reliable communications between two XYR 400E modules, then a third XYR 400E module may be used to receive the message and re-transmit it. This module is referred to as a repeater. This module may also have a host device connected to it.

The XYR 400E unit has two antenna connections at the top of the module, allowing two antennas to be fitted to the unit. The left connector (looking at the front) labeled “RX” is connected only to the internal wireless receiver. The right connector labeled TX/RX is connected to both the transmitter and receiver.

Note: when only one antenna is used, it must be connected to the right TX/RX connector.

Version 1 XYR400E Ethernet Modem 12 5/1/08

Plant and factory installations

Most installations in industrial plants and factories use a single omni-directional antennas. Installations can suffer from “multi-path fading” effects where multiple reflected radio signals adversely affect the signal strength. This can be checked by moving the antenna a short distance (10 cm or 4 inches) - if the signal increases significantly then there are multi-path effects.

In a “static” installation, where the radio path is not changing, moving an antenna to the position of maximum signal solves this problem. However where the radio path changes because the XYR 400E is mounted on moving equipment, or if there is moving equipment in the area, then the solution is to use two antennas. Because the two connectors are separated, the RF signal at each connector will be different in the presence of multi-path fading. The XYR 400E unit will automatically select the higher RF signal.

Note that directional antennas are not normally used in plant and factory installations.

Line-of-sight installations

In longer line-of-sight installations, the range may be increased by using a high gain antenna on the TX/RX connector. However the gain should not cause the effective radiated power (ERP) to exceed the permitted value. A second higher gain antenna can be connected to the RX connector without affecting ERP - this will increase the operating range provided the background noise in the area is low.

Antennas

Antennas can be either connected directly to the module connectors or connected via 50 ohm coaxial cable (eg RG58 Cellfoil or RG213) terminated with a male SMA coaxial connector. The higher the antenna is mounted, the greater the transmission range will be, however as the length of coaxial cable increases so do cable losses.

The net gain of an antenna/cable configuration is the gain of the antenna (in dBi) less the loss in the coaxial cable (in dB). The maximum net gain of the antenna/cable configuration connected to the TX/RX connector is 0dB in Europe (100mW ERP). In USA, Canada and Australia (4W ERP), the maximum gain is 12dB for the XYR 400E-300 or 16dB for the XYR 400E-100. There is no gain restriction for antennas connected to the RX connector.

13 XYR400E Ethernet Modem Version 1 5/1/08

The gains and losses of typical antennas are

Antenna Gain (dBi)

Dipole 2

Collinear 5 or 8

Directional 10 - 28

Cable type Loss (dB per 10 m / 30 ft)

RG58 Cellfoil -6

RG213 -5

LDF4-50 -1.5

The net gain of the antenna/cable configuration is determined by adding the antenna gain and the cable loss. For example, a 5dBi antenna with 10 metres of Cellfoil has a net gain of -1 dB (5dB – 6dB).

Installation tips

Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture. Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the radio losses. We recommend that the connection be taped, firstly with a layer of PVC Tape, then with a vulcanizing tape such as “3M 23 tape”, and finally with another layer of PVC UV Stabilized insulating tape. The first layer of tape allows the joint to be easily inspected when trouble shooting as the vulcanizing seal can be easily removed.

Where antennas are mounted on elevated masts, the masts should be effectively earthed to avoid lightning surges. For high lightning risk areas, surge suppression devices between the module and the antenna are recommended. If the antenna is not already shielded from lightning strike by an adjacent earthed structure, a lightning rod may be installed above the antenna to provide shielding.

2.2.1 Dipole and Collinear antennas

A dipole or collinear antenna transmits the same amount of radio power in all directions - as such that are easy to install and use. The dipole antenna with integral 5 metres (15 feet) cable does not require any additional coaxial cable, however a cable must be used with the collinear antennas.

Collinear and dipole antennas should be mounted vertically, preferably 30 cm (1 foot) away from a wall or mast to obtain maximum range.

2.2.2 Directional antennas.

Directional antennas can be



a Yagi antenna with a main beam and orthogonal elements, or



a directional radome, which is cylindrical in shape, or



a parabolic antenna.

A directional antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to compensate for coaxial cable loss for installations with marginal radio path.

DIRECTIONAL

Yagi antennas should be installed with the main beam horizontal, pointing in the forward direction. If the Yagi is transmitting to a vertically mounted omni-directional antenna, then the Yagi elements should be vertical. If the Yagi is transmitting to another Yagi, then the elements at each end of the wireless link need to in the same plane (horizontal or vertical).

Directional radomes should be installed with the central beam horizontal and must be pointed exactly in the direction of transmission to benefit from the gain of the antenna. Parabolic antennas should be mounted as per the manufacturer’s instructions, with the parabolic grid at the “back” and the radiating element pointing in the direction of the transmission.

Ensure that the antenna mounting bracket is well connected to “ground/earth”.

2.3 Power Supply

The XYR 400E module can be powered from a 9 - 30VDC power supply. The power supply should be rated at 1 Amp. The positive side of the supply must not be connected to earth. The supply negative is connected to the unit case internally. The DC supply may be a floating supply or negatively grounded.

The power requirements of the XYR 400E unit is 240mA @ 12V or 150mA @ 24VDC. This is inclusive of radio and Ethernet ports active, & serial port plugged in. Transmission current is nominally 350mA at 12V (200mA at 24V)

2.4.2 RS485 Serial Port

The RS485 port provides for communication between the XYR 400E unit and its host device using a multi-drop cable. Up to 32 devices may be connected in each multi-drop network.

As the RS485 communication medium is shared, only one of the units on the RS485 cable may send data at any one time. Thus communication protocols based on the RS-485 standard require some type of arbitration.

RS485 is a balanced, differential standard but it is recommended that shielded, twisted pair cable be used to interconnect modules to reduce potential RFI. It is important to maintain the polarity of the two RS485 wires. An RS485 network should be wired as indicated in the diagram below and terminated at each end of the network with a 120 ohm resistor. On-board 120 ohm resistors are provided and may be engaged by operating the single DIP switch in the end plate next to the RS485 terminals. The DIP switch should be in the “1” or “on” position to connect the resistor. If the module is not at one end of the RS485 cable, the switch should be off.

2.5 Discrete (Digital) Input/Output

The XYR 400E has one on-board discrete/digital I/O channel. This channel can act as either a discrete input or discrete output. It can be monitored, or set remotely, or alternatively used to output a communications alarm status.

If used as an “input”, the I/O channel is suitable for voltage free contacts (such as mechanical switches) or NPN transistor devices (such as electronic proximity switches). PNP transistor devices are not suitable. Contact wetting current of approximately 5mA is provided to maintain reliable operation of driving relays.

The digital input is connected between the "DIO" terminal and common "COM". The I/O circuit includes a LED indicator which is lit when the digital input is active, that is, when the input circuit is closed. Provided the resistance of the switching device is less than 200 ohms, the device will be able to activate the digital input.

The I/O channel may also be used as a discrete output. The digital outputs are transistor switched DC signals, FET output to common rated at 30VDC 500 mA.

The output circuit is connected to the "DIO" terminal. The digital output circuit includes a LED indicator which is lit when the digital output is active.

attempt to establish a link with an Access Point whose beacon indicates a matching SSID. Access Points do not initiate link establishment.

“Client” Start-up

When a Client powers up, it scans for beacons from Access Points. While a link is not established, the Client cyclically scans all available channels for a suitable Access Point. The Client will attempt to establish a link with an Access Point only if it has matching SSID and other compatible capabilities as indicated by the beacon. If more than one suitable Access Point is discovered, the client will attempt to establish a link with the Access Point that has the strongest radio signal.

Link Establishment

Once a Client identifies a suitable Access Point for link establishment it attempts to establish a link using a two step process – “Authentication” and “Association”. During Authentication the Client and Access Point check if their configurations permit them to establish a link. Once the Client has been authenticated, it will then request an Association to establish a link.

Status of the wireless link is indicated via the Link LED. For an Access Point, the Link LED will be OFF while no links have been established. Once one or more links have been established, the Link LED is ON. For a Client, the Link LED will reflect the connection status to an Access Point. Link status is also displayed on the “Connectivity” page of the web interface.

After the link is established, data may be transferred in both directions. The Access Point will act as a master-unit and will control the flow of data to the Clients linked to it. Clients can only transmit data to the AP to which they are connected. When a Client transfers data to another Client, it first transmits the data to the AP which then forwards the data to the destined Client.

Presence of a “link” does not mean that the connected unit is authorized to communicate over radio. If the encryption keys are incorrect between units in the same system, or a dissimilar encryption scheme is configured, the LINK led will light, however data may not be passed over the wireless network.

A maximum of 255 Clients may be linked to an Access Point.

How a Link connection is lost

The Access Point refreshes the link status with a Client every time a message is received from that Client. If nothing is received from a Client for a period of 120 seconds, the Access Point sends a “link-check” message. If there is no response to the link-check a De-authenticate message is sent and the link is dropped.

A Client monitors beacons from an Access Point to determine whether the link is still present. If the Client can no longer receive beacons from the AP, the AP is considered to be out-of-range and the link is dropped. Whenever a Client is not connected to an AP, it will cyclically scan all available channels for a suitable AP.

Roaming

Clients may also roam between Access Points. If a Client receives a beacon from an AP with a stronger signal than the current AP (providing SSID is the same and capability information are compatible), it may disconnect from the first AP and establish a link with the second AP. This functionality permits a client to have mobility whilst maintaining a link with the most suitable AP.

The 100MB LED indicates that the connection is at 100 MBit/Sec. The 100MB LED will be off for 10MB/Sec connection.

Other conditions indicating a fault are described in Chapter Six Troubleshooting.

3.2 Selecting a Channel

The XYR 400E conforms to the IEEE 802.11 Wireless LAN specification. The XYR 400E supports 11 radio channels, each 5MHz wide, in the range 2412MHz to 2462MHz. Only one of these channels is used for a connection. The desired channel is selected and configured at the Access Point, and is then used for all beacon transmissions and connections. Clients scan all 11 channels for a suitable Access Point and then adopt the same channel as the AP when a connection

21 XYR400E Ethernet Modem Version 1 5/1/08

is established. Although each channel is only 5MHz wide, the radio transmission is a lot wider. Hence the channels overlap. The following diagram shows the RF energy distribution for a WiFi transmission:

f-33 f-22 f-11 f f+11 f+22 f+33

RF power distribution in a WiFi transmission with channel central frequency, f

Most of the energy is in a central 22 MHz wide “lobe”, centred around the channel frequency, however there are also side-lobes extending either side.

If we ignore the side lobes and consider each WiFi message as a 22MHz wide transmission, then the following diagram represents how transmissions in each channel overlaps.

If there is more than one WiFi AP within the same wireless range, then it is important that the AP’s are on channels as far apart as possible. If there are only two AP’s, then set them to 1 and 11. If there are three, set them to 1, 6, 11.

It is also important that correct channel is selected for region. Channels 1 to 11 are approved for North America (FCC), Europe (ETSI), Canada (IC) and Australia (ACMA). Channels 10 and 11 are approved for use in Spain and France. Refer to the relevant regulatory authority for the region as to which radio channels are approved for use.

3.3 Default Configuration

The default factory configuration of the XYR 400E is

• Client/Bridge/

• IP address192.168.0.1XX, where XX is the last two digits of the serial number (the default IP

address is shown on the printed label on the back of the module)

• netmask 255.255.255.0

• Username is “user” and the default password is “user”

The XYR 400E will temporarily load some factory-default settings if powered up with the Factory Default switch (on the end-plate of the module) in SETUP position. When in SETUP mode, wireless operation is disabled. The previous configuration remains stored in non-volatile memory and will only change if a configuration parameter is modified and the change saved.

Do not forget to set the switch back to the RUN position and cycle power at the conclusion of configuration for resumption of normal operation.

3.4 Configuring the Unit for the First Time

The XYR 400E has a built-in web server, containing webpages for analysis and modification of configuration. The configuration can be accessed using Microsoft® Internet Explorer. This program is shipped with Microsoft Windows or may be obtained freely via the Microsoft® website.

Configuration of IP address, gateway address and subnet mask may also be accessed via the RS-232 serial port.

Accessing Configuration for the first time

There are two methods for accessing the configuration inside a XYR 400E. The first method requires changing your computer settings so that the configuring PC is on the same network as the XYR 400E with factory default settings. This is the preferred method and is much less complicated than the second method. You will need a “straight-through” Ethernet cable between the PC Ethernet port and the XYR 400E. The factory default Ethernet address for the XYR 400E is

192.168.0.1XX where XX are the last two digits of the serial number (check the label on the back of the module).

The second method requires setting an IP address in the XYR 400E such that it is accessible on your network without having to change your network settings.

3.4.1 Set PC to same network as XYR 400E

Connect the Ethernet cable between unit and the PC configuring the module.

• Set the Factory Default Switch to the SETUP position. This will always start the XYR 400E

with Ethernet IP address 192.168.0.1XX, subnet mask 255.255.255.0, gateway IP 192.168.0.1 and the radio disabled. Do not forget to set the switch back to the RUN position and cycle power at the conclusion of configuration for resumption of normal operation.

23 XYR400E Ethernet Modem Version 1 5/1/08

• Power up the XYR 400E module.

• Open “Network Settings” on your

PC under Control Panel. The following description is for Windows XP - earlier Windows operating systems have similar settings.

address 192.168.0.1, Subnet mask 255.255.255.0, and default gateway 192.168.0.1.

Version 1 XYR400E Ethernet Modem 24 5/1/08

• Open Internet Explorer and ensure that settings will allow you to connect to the IP address

selected. If the PC uses a proxy server, ensure that Internet Explorer will bypass the Proxy Server for local addresses. This option may be modified by opening Tools -> Internet Options > Connections Tab -> LAN Settings->Proxy Server -> bypass proxy for local addresses.

• Enter the default IP address for the XYR 400E http://192.168.0.1XX where XX is the last two

digits of the serial number

• A welcome webpage should be displayed as illustrated below.

• Configuration and Diagnostics may be opened by clicking on any of the menu items, and

entering the username “user” and default password “user”. Configure the unit to your requirements (refer later sections of this manual).

When Configuration is complete, switch Factory Default dip-switch on XYR 400E to RUN position, and cycle power to resume normal configured operation.

3.4.2 Set XYR 400E to same network as PC

This is the alternate procedure to setting an IP address in the XYR 400E. Consult your network administrator for an IP address on your network, the gateway IP address, and network mask.

a) Switch Factory Default dip-switch on XYR 400E to SETUP position.

b) Connect the RS232 port on the XYR 400E to the RS232 port on the PC using a “straight-

through” serial cable.

c) Open a terminal package (such as Hyperterminal) with 19200bps data rate, 8 data bit, 1 stop, no

parity and no flow control. Make sure that no other programs have control of the serial port.

d) Power up XYR 400E. Basic network settings will be displayed on the terminal as illustrated

below. When prompted, hit enter key to stop automatic boot process. You have 5 seconds to abort the boot process.
