System Overview
1.0
SYSTEM OVERVIEW
SiteScan Web uses a network of microprocessor-based control modules to monitor and control Liebert
air, power, UPS and other critical equipment.
SiteScan Web enables the user to monitor and control equipment in a single building, an entire
campus or a network of facilities around the globe. A SiteScan Web system utilizes a Web-based
server running Windows XP, 2003 Server or 2000 and a conventional Web browser to gather
information, change operating parameters, run reports and perform similar functions on various
types of critical equipment.
A central Web-based server communicates with control modules and generates Web pages, which the
customer can access using a conventional Web browser. Through SiteScan Web, the customer can
gather information, change operating parameters, run reports and perform other critical monitoring
system functions on equipment in a single facility or in dozens of locations.
The Web server and Liebert gateway communicate over an Ethernet network. The Liebert gateway
communicates to the Liebert control modules using the Control Module network (CMnet) and the
ARCnet156 protocol. The control modules communicate with the Liebert environmental and power
equipment using the Information Gathering Network (IGMnet) or to contact closure equipment using
a signal cable.
Customers access the information presented as a result of these functions using a Web browser.
Internet Explorer is the browser supported by the SSWEB server.

Product Description
2.4
SiteLink Modules
A SiteLink module receives IGM protocol from Liebert environmental and power equipment and converts it to BACnet over ARCnet for communication to a Liebert gateway.
In this section you will have to determine the type of SiteLink needed to monitor the Liebert equipment. To do this, determine how many Liebert units you have and where are they located.
NOTE
Due to distance requirements of the IGM (EIA-422) cable, the location of the units being
monitored may affect the number of SiteLinks needed, more than the number of monitored
units themselves.
Consider the layout of the equipment. The Liebert units communicate over a twisted pair of
wire that is “home-run” between the unit and the SiteLink module. The distance of this wire
should not exceed 1500 ft. (457m). Consult 7.0 - Wiring Guidelines for wire specifications.
Each SiteLink features:
• Two serial ports—one EIA-232, DB-9 male, and one EIA-485/232, 2 / 4 wire screw terminal connector—both 38.4K/9600 bps selectable for third-party connections
• One access port for diagnostics and flash installation
• Four or twelve EIA-422, two-wire screw terminal ports for Liebert equipment connections
• One Control Module network port EIA-485 twisted pair, ARC156K/38.4K/9600 bps selectable,
optically isolated
NOTE
Each SiteLink unit requires a separate 24VAC power supply; use XFMR24 for U.S.
installations (see 2.7.3 - XFMR24 - 24V Transformer).

Module Accessories
2.7.1
GXEXP - Expander Cable
The Site I/O Expander Cable is an 18-inch long or 24-inch long expander cable used between the
Site I/O X8/0 modules. Because expander modules plug directly into the side of the adjoining module,
the grouping tends to become very long in the horizontal direction. Use only one (1) GXEXP cable to
break up this horizontal length.
2.7.2
RCM10PSKIT - Power Supply Kit
The 24VDC power supply kit to be used with the Site I/O modules and four-wire analog transducers
must be mounted outside the Site I/O module. This power supply is needed only when four-wire transducers are used. This power supply will accommodate a Site I/O 32/0 fully loaded with 4-20mA transducers.
2.7.3
XFMR24 - 24V Transformer
Each SiteLink, Site I/O and SiteTPI module requires a 24-volt transformer. This model requires a primary of 120VAC, 50-60Hz wall plug (American Duplex) to 24VAC @ 40VA secondary. The secondary

ARCnet Communication Enhancement Devices
In SiteScan Web systems, ARCnet, or ARC156, is the standard for module-to-module communications. Formerly, this was termed CMnet in SiteScan 2000/2W systems. The main difference is the control module network now operates at a faster baud rate (156K baud with ARCnet vs. 9600 or 38.4K
baud with CMnet). The increase in speed requires a low impedance / low capacitance wiring. Also, all
control modules must be wired in a daisy-chain configuration.
ARCnet enhancement devices can be used to control and maintain the proper biasing of the ARCnet
network.
2.8.1
ARC156-KIT - ARCnet Kit
The ARC156-Kit contains a PROT485 surge protection board and a DIAG485 diagnostic board within
the same site enclosure. This kit must be installed near the midpoint of each ARCnet segment.
Requires 24VAC supply (not included).
2.8.2
Other ARCnet Parts
ARCDIAG485 - ARCnet156 Diagnostics Board
The ARCnet156 diagnostics board in an enclosure provides visual indication of signal levels and adds
bias to reduce the effect of noise on a segment. More than one DIAG485 can be installed on a specific
ARCnet segment.
NOTE
Only one DIAG485 within an ARCnet segment should have its bias jumper in place.
ARCDIAG485WO - ARCnet156 Diagnostics Board Without Enclosure
The ARCnet156 Diagnostics Board is available without an enclosure. Requires 24VAC supply (not
included).
NOTE
Install one 120 ohm terminating resistor at the beginning and end of each segment unless the
segment is less than 10 ft. (3m) long (included with ARCDIAG485).
ARCPROT485 - ARCnet156 Surge Protection Board
The ARCPROT485 is an ARCnet device used for surge suppression. It is recommended that this
device be installed at every entrance and exit of a building.
ARCPROT485WO - ARCnet156 Surge Protection Board Without Enclosure
The ARCnet156 surge suppressor device is available without enclosure.
ARCREP485 - ARCnet156 Repeater Board (Signal Booster)
The ARCnet156 Repeater boosts the ARCnet156 network signals and extends the length of the network by joining one segment to another for EIA-485 networks running from 1200 bps to 156 Kbps.
Requires 24VAC supply (not included).
When designing your system, factor in the maximum wiring distance of 2,000 ft. (610m) per segment.
(A segment is up to 32 modules.) If your system requires more than 32 modules per segment or
exceeds the distance of 2,000 ft. (610m), install another gateway or, possibly, use an ARCREP485.
The signal becomes weaker as distance increases.
ARCREP485WO - ARCnet156 Repeater Board Without Enclosure
The ARCnet156 signal booster (repeater) is available without enclosure.

Upgrading SiteScan 2000 Systems to SiteScan Web
4.1
Upgrade Overview
SiteScan Web Upgrade comes with all the same basic functionality as SiteScan Web.
SS2000 or 2W serial numbers must be retired for a customer to qualify for upgrade pricing.
Where to Find Serial Numbers
The 10-digit software serial numbers can be found:
• On the original installation disks
• On the startup splash screen (log-in) of the software
• By choosing Help, then About from the drop-down menu within the software
Possible Additional Charges
Additional charges that may apply include:
• Each current SS2000 graphic will require a HIGRAPHICUP to upgrade the existing graphic for
use in SiteScan Web.
• The gateway module must be a SiteGate-E or SiteGate-ETH. The system will not operate with a
SiteGate-232.
• The DC12-i422 and DC4-i422 modules must be replaced with SiteLink modules.
What We Need From You or the Customer:
• A valid SS2000 / SS2W license is necessary for the upgrade. Software serial numbers must be
submitted and retired before the upgrade software will be shipped.
• A backup of the current SS2000 configuration files. Your local LGS Site Specialist may have a
current copy. Consult LGS as necessary.
Compatibility: CMnet vs. ARCnet
When a customer upgrades a SiteScan 2000W or 2W system, only the legacy SiteScan application is
upgraded.
Replacing a SiteGate-232 or DCLan with a SiteGate-E enables the SiteScan Web server to communicate with the modules on the CMnet. Essentially, it is a SiteScan Web front-end communicating with
SiteScan 2000W/2W hardware.
To upgrade the CMnet to ARCnet, all modules must be ARCnet-compatible. In most cases this will
require replacement of some modules. Also, the CMnet wire must be replaced with the Magnum cable
(A3-ARC-156-2). Currently the following devices are not ARCnet-compatible:
•

4.2.1
Target Application
A typical application for this upgrade might be:
• Customer wants to upgrade a SiteScan 2W system.
• Existing system uses a SiteGate-232 module.
4.2.2
Description
To upgrade a SS2W system that currently uses a SiteGate-232, replace the SiteGate-232 with a
SiteGate-E. Since the SS2W system does not support graphics, there is no need to order any upgrade
graphic parts. Simply upgrade the customer’s system to a SiteScan Web version of the SS2W system.
The system will be built as a text-only version of SiteScan Web.
NOTE
Customers may have to replace the computer running SS2W if it does not meet the minimum
operating requirements for SiteScan Web (see Table 1 in 2.1.1 - SSWEB - SiteScan Web
Base Product). In addition, that computer must be connected to an Ethernet network.

THIRD-PARTY AND BUILDING MANAGEMENT INTERFACES
SiteScan Web monitoring products can provide multiple paths for integrating to and with third-party
equipment and software. Through BACnet over IP, SiteScan Web software allows you to interface
with more than one building management system (BMS) at a time. The SiteLink hardware is designed
to communicate concurrently with SiteScan Web and a BMS using Modbus over EIA-232 or EIA-485.
5.1
SiteScan Web and BACnet/IP to BMS
5.1.1
Target Application
A typical application might be:
• Customer has a BMS front-end that is used by the facility manager.
• Two new computer rooms need to be monitored by BMS and IT Manager.
• Each computer room will have:
• 3 Liebert environmental units
• 1 STS2/PDU
• 2 NPower UPSs
• 4 analog sensors
• 2 strobe lights for alarm conditions
• One local user is allowed.
5.1.2
Description
This configuration is ideal for customers who have a current investment within their BMS and require
the IT Manager’s access to their business unit. SiteScan Web server natively communicates
BACnet/IP to its Ethernet-ready gateway modules. This same protocol is available to any BMS frontend that supports BACnet/IP.

BMS Front-End Interfacing to Liebert Equipment by EIA-485 Modbus
Modbus is an industry standard means of communicating between systems from different vendors. A
SiteScan Web system using Modbus allows a Third Party to request information from a SiteLink,
With SiteScan Web, single or multiple SiteLinks can communicate to other systems using Modbus on
either Port A or Port B.
Both ports send out Modbus information. They differ in that Port A is configurable for RS-232 or twoor four-wire RS-485 media access. Port B is DB-9 and RS-232 only.
5.3.1
Port A—RS-485 Modbus
When configured for RS-485, this allows Port A to be daisy-chained with multiple SiteLinks. In this
example, both the SiteLinks and the third-party device use a five-screw terminal to make the wiring
connection. When using RS-485 each SiteLink or the third-party equipment is between 1250 and
4,000 ft. (381-1219m) away depending on the baud rate being used. Make this connection with
shielded or unshielded twisted pair wiring.

ARCNET156
6.1
ARCnet156 CMnet Components
The SSWEB-Liebert gateways and control modules communicate using ARCnet156, a token-passing
protocol running at 156 Kbps. ARCnet156 requires network boards to properly terminate, bias, protect and repeat data transmitted over the twisted pair EIA-485 segment.
An ARC156-Kit should be used for every gateway module. The kit filters out some signal noise and
provides diagnostic information about the ARCnet156 network. Two 120 ohm terminators are
included with each ARC156-Kit.
6.2
Segment Requirements
An ARCnet156 segment is an arrangement of gateways, control modules and ARCnet156 devices up
to 2,000 ft. (610m) long.
A segment must:
•
•
•
•
•
•
Be wired in a daisy chain (see Figure 20).
Have an ARC156-KIT installed in the middle of the segment.
Have a PROT485 installed at each building entrance and exit.
Have one ARC156-KIT for every 32 modules and each 2,000 ft. (610m) of equipment and cabling.
Not exceed 50 modules including ARCnet enhancement devices.
Have a 120 ohm terminator at each end unless the segment is less than 10 ft. (3m) long.
NOTE
Each segment must use a Magnum ARC cable.

ARCnet156
6.3
Terminations
At 156 Kbps, a signal reaching the end of an unterminated cable can echo, or reflect back, creating a
distortion in the signal and degrading the quality of the communications. To prevent this, every segment on the ARC 156 network must have a 120 ohm terminator placed at each end of the segment.
To insert the 120 ohm terminator, make sure the module’s power is turned off and attach the terminator to the CMnet positive and negative terminals. The 120 ohm terminating resistors are included
with the ARC156-KIT.
6.4
Wiring Recommendations
If bare communication wire comes in contact with the cable’s foil shield, drain/shield wire or a metal
surface other than the connector, the module might not communicate. When connecting the wire, follow these guidelines:
• When stripping the outer jacket, take care not to nick the inner insulation. The wire’s outer jacket
is brittle enough to work free after being nicked or partially cut. Do not strip more than 1 in.
(25mm) of the outer jacket. See Figure 21.

6.5
Cable Shields
Connect the shields as shown in Figure 23. The shields should be connected at each module’s shield
connection terminal.
Do not ground the shield to earth ground or to the module’s power ground. The PROT485 and the
individual modules allow the shield to float a limited amount so that there are no ground loops. But if
the voltage on the shield becomes too great relative to the earth ground, then the excess voltage is
bled off with protective devices on the PROT485 or on the modules.
Figure 23 Using shielded cable

6.6
Noise
Do not run AC power wires or the module’s relay output wires next to the communication wires or
sensor input wires.
Table 21 lists common sources of noise that can affect signal quality. Try to avoid these sources of
noise when running communication or sensor wiring. If noise is a problem and it is not possible to
move the wiring, use ferrite clamp-on chokes on the cabling to help improve signal quality.

6.7
Upgrading to ARC156
Before upgrading a legacy CMnet to ARC156, you must:
• Ensure adequate wiring. See 6.4 - Wiring Recommendations for details.
• Verify the network configuration is acceptable. See 6.2 - Segment Requirements.
• Use the appropriate network accessories—for example, 120 Ohm terminators and REP485
repeaters.
• Make sure all modules are capable of using Exec 6.0 or later. Refer to the Technical Instructions
for each module or to the Technical Handbook to determine this.
Follow these steps to upgrade the CMnet to ARC156:
1. While the CMnet is running at 38.4 Kbps or 9600 bps, transfer an Exec 6.0 (or higher) driver into
every module.
This can be done over a Direct Connection through a gateway module, or by setting the module for
38.4 Kbps or 9600 bps and Direct Network connecting to the module’s Access Port using an APT
in 485 mode.
2. Add a 120 Ohm terminator to each end of the network segment.
3. Add at least one ARC156-KIT to the middle of the network segment. Set the bias jumper to add
bias.
You can have more than one ARC156-KIT per network segment, but no more than one
ARC156-KIT should have the bias jumper set to add bias.
4. Go to each module and set the CMnet baud rate jumper for 156 Kbps communication.
Once you change the module’s baud rate, the module can no longer communicate on the CMnet.
When all modules are set to use 156 Kbps communications, a network reconfiguration is required
to start the ARC156 CMnet.
5. To reconfigure the CMnet immediately, remove and then restore power to one of the modules.
Otherwise, wait up to 30 minutes for the modules to reconfigure themselves.
NOTE
A CMnet divided into segments may experience several reconfigurations until all the segments
are synchronized.
6. Add other devices (like a REP485 or PROT485) to the CMnet as necessary to improve the signal
quality.

Terminology
APPENDIX A - TERMINOLOGY
ARCnet
The protocol used for communications between the Liebert gateway and the Liebert control modules.
This is a token-passing protocol where each module transmits information to the gateway in turn
based on its physical address.
BACnet
Data communication protocol for Building Automation and Control Networks (BACnet). It uses IDs to
identify all points that are part of the configuration, such as the SSWEB server, BACnet and ARCnet
networks, gateways and control modules. Referred to as Object IDs, these IDs make sharing
information between devices a relatively simple task using BACnet. Developed under the auspices of
the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), BACnet
is now an American national standard, a European pre-standard, and a potential global standard.
ASHRAE Standing Standard Project Committee supports and maintains the protocol.
For details, go to:
www.bacnet.org
CMnet
The network connecting the Liebert gateway and the Liebert control modules. Daisy chain up to
50 control modules per Control Module net, or CMnet.
The CMnet can consist of any combination of the following: SiteLink-12-ARC, SiteLink-4-ARC,
SiteI/O 10/0-ARC, SiteI/O 16/16-ARC, SiteI/O 32/0-ARC, SiteI/O X8/0 and SiteTPI-M-ARC, Third
Party Interface (TPI) modules.
Control Module
A device connected to the CMnet. This includes Ethernet gateways, SiteLink modules and Site I/O
modules and TPI modules.
Ethernet Backbone
Wiring and communications equipment permitting multiple computers to share information and
resources using the Ethernet media access type.
LAN / WAN
Any Local Area Network or Wide Area Network using the Ethernet media access type.
Gateway
A device that performs protocol conversion between different types of networks or applications. The
Liebert gateway receives BACnet over ARCnet protocol from the Liebert control modules and converts it to BACnet over IP for protocol communication to the SSWEB server. The Liebert SiteLink
modules receive IGM protocol from the Liebert environmental and power equipment and convert it to
BACnet over ARCnet protocol for communications to the Liebert gateway.
HTTP
Rules for exchanging files (text, graphic images, sound, video, and other multimedia files) between
browsers. Your Web browser is a hypertext transfer protocol client, sending requests to the SiteScan
Web Sever. When the browser user enters file requests by either opening a Web file or clicking on a
hyperlink, the browser builds an HTTP request and sends it to the Web server. The Web server
receives the request and returns it after necessary processing.
IGMnet
Information Gathering Module Network is the protocol that SiteLinks use to communicate to the Liebert units over the EIA422 connection type. It is a point-to-point protocol, where one device connects
directly to another and only those two devices communicate with each other.
37
Terminology
Liebert Gateway
Also referred to as a router, the Liebert gateway routes information between the Web server and the
Liebert control modules. It uses an Ethernet network and the TCP/IP and BACnet protocols, also
referred to as BACnet over IP.
Half Router
A function of a Liebert gateway. If no Ethernet connection is available to the customer’s network, a
Liebert gateway can communicate using a modem to a second Liebert gateway and serve the function
of one Liebert gateway connected to the backbone.
Media
The physical substance that carries data. SiteScan Web media are Category 5 Ethernet cables and
various types of Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP) cables.
Media Access Types
Protocols used to access media. SiteScan Web media access protocols are Ethernet, RS-485, RS-422
and ARCnet156. Ethernet uses a Carrier Sense Multiple Access Collision Detection (CSMA/CD)
schemes where multiple devices sense signals on the media simultaneously, access the media when
they hear no signals and detect collisions that cause retransmission of information. RS-485 and
RS-422 are point-to-point protocols. Point-to-point protocols transmit information directly from one
device to another. ARCnet156 is a token-passing protocol. Token-passing protocols give each device a
designated period to transmit information after it receives permission (a token) based on its physical
address.
Modbus
A building management standard protocol for interfacing devices from different vendors. It provides
client/server communication between devices connected on different types of buses or networks. It is a
request-reply protocol and offers services specified by function codes. Modbus function codes are elements of Modbus request/reply PDUs.
For more information, go to:
www.modbus.org
Network Management System
Software system to track and configure equipment on a network. It displays information about
devices on the network that have IP addresses and also sends and receives information to SNMP protocol devices.
Point
Graphics in the SiteScan Web system. For example, a point is one value displayed from the Liebert
unit, such as temperature. The IGM reference library lists possible points for each Liebert unit. Point
also refers to any value obtained via a contact into the SiteScan system; for example, “Temperature”
from a thermistor is a point.
Protocols
Conventions governing the treatment and the formatting of data in an electronic communications system. SiteScan Web protocols are Transmission Control Protocol/Internet Protocol (TCP/IP), Building
Automation and Control networks (BACnet), Attached Resource Control Network (ARCnet), and
Information Gathering Module Network (IGMnet). TCP/IP establishes a connection between two
devices and controls the transmission of information using the IP address of each device. BACnet
broadcasts requests for information to devices based on a network or device number (network ID or
object ID) and the devices respond back. ARCnet transmits a token to devices based on their physical
address. IGM sends requests to Liebert equipment based on a set of codes for unit, status, alarm and
control information.

Terminology
Router
A device that forwards data packets from one local area network (LAN) or wide area network (WAN)
to another. Based on routing tables and routing protocols, routers read the network address in each
transmitted frame and send it based on the most expedient route. In SSWEB, the Liebert gateways
route BACnet over IP traffic from one segment to another.
SNMP
Simple Network Management Protocol; a protocol to manage devices. SNMP sends traps that signify
alarm conditions within a device. It uses other commands to allow control and to monitor a device.
STP
Shielded Twisted Pair cable is protected with an aluminum or copper sheet or stranding to reduce
electromagnetic interference. Twisted strands in the cable cancel out the effects of electromagnetic
frequency caused by current flowing through each wire in the cable.
STP Plenum Cable
is Shielded Twisted Pair with insulation that will not produce poisonous fumes if it burns, as national
codes require for cable installed in an air duct. STP Plenum cable also is protected with an aluminum
or copper sheet or stranding to reduce electromagnetic interference. Twisted strands in the cable cancel out the effects of electromagnetic frequency caused by current flowing through each wire in the
cable.
URL
Uniform Resource Locator, the global address of documents and other resources on the World Wide
Web. The first part of the address indicates what protocol to use, and the second part specifies the IP
address or the domain name where the resource is located. For example, the following URL specifies a
Web page that is be fetched using the HTTP protocol:
http://www.pcwebopedia.com/index.html
UTP
Unshielded Twisted Pair cabling is not shielded against electromagnetic interference. Twisted
strands in the cable cancel out the effects of electromagnetic frequency caused by current flowing
through each wire in the cable.
UTP Plenum Cabling
Unshielded Twisted Pair Plenum cabling has insulation that will not produce poisonous fumes if it
burns, as national codes require for cable installed in an air duct. The cabling is not shielded against
electromagnetic interference. Twisted strands in the cable cancel out the effects of electromagnetic
frequency caused by current flowing through each wire in the cable.
