Overview
The BACnet™ Communication Interface for Chillers (BCI-C) is comprised of a Tracer™ UC400
controller with interface software. It is a non-programmable communications module that allows
heating, ventilation, and air-conditioning (HVAC) equipment to communicate on a BACnet
communications network.
This guide provides:
•
A brief overview of the BACnet protocol
•
Flowchart to setup the BCI-C
•
Getting started
•

A glossary of terms
Note: Users of this guide should have basic knowledge of BACnet protocol. For more detailed
information about this protocol, visit the company web site listed under “Additional
Resources,” p. 31.
BACnet Protocol
The Building Automation and Control Network (BACnet and ANSI/ASHRAE Standard 135-2004)
protocol is a standard that allows building automation systems or components from different
manufacturers to share information and control functions. BACnet provides building owners the
capability to connect various types of building control systems or subsystems together for a variety
of reasons. In addition, multiple vendors can use this protocol to share information for monitoring
and supervisory control between systems and devices in a multi-vendor interconnected system.
The BACnet protocol identifies standard objects (data points) called BACnet objects. Each object
has a defined list of properties that provide information about that object. BACnet also defines a
number of standard application services that are used to access data and manipulate these objects
and provides a client/server communication between devices. For more information on BACnet
protocol, refer to “Additional Resources,” p. 31.
BACnet Testing Laboratory (BTL) Certification
The BCI-C supports the BACnet communication protocol and has been designed to meet the
requirements of the application-specific control profile. For more details, refer to the BTL web site
at www.bacnetassociation.org.

Set device addresses on the BCI-C rotary switches (see following section).
•
Select either wired or wireless communication using the link select switch on the BCI-C.
•
Configure the BCI-C by using either the Tracer BACnet Setup Tool (BST) or Tracer TU.
– The default baud rate is 76,800 bps.
– The default software device ID is the MAC address.
– The device units do not have defaults; the BST or Tracer TU will display the device units of
the controller to which it is connected.
Configuring the BCI-C
The BCI-C can be configured using either the Tracer™ BACnet Setup Tool or the Tracer™ TU service
tool.
Note: The BCI-C controller is configured from the factory for use with a typical Tracer SC based
systems. Additional configuration is necessary if a baud rate, device ID, or engineering units
are needed with the BACnet system being used. Additionally, the BCI-C self-configures its
BACnet points to match the unit type upon initial power-up.
Using the BACnet Setup Tool
This section describes how to configure the BCI-C controller using the Tracer BACnet Setup Tool.
Online help is available by clicking the help
icon located in upper right portion of the screen.
1. Open the Tracer BACnet Setup Tool and the Controller Settings screen appears (Figure 1).

Understanding the MAC Address and BACnet Device ID
MAC Address
The MAC address is the rotary dial address. For Trane systems, this address must be between 1 and
127. Although “0,0,0,” is a valid BACnet address, Trane reserves this address for the Tracer SC
controller. All devices on the BACnet MS/TP link must be unique. For non-Trane SC systems, see
“Rotary Dial Address Settings for Non-Trane SC Systems,” p. 10.
BACnet Device ID
Tracer SC uses the rotary dial settings (MAC address) to create the BACnet device ID. The Tracer
SC adds an SC rotary dial address and a link number to artificially create a unique BACnet Device
ID for each node. To manually set rotary dial settings, refer to the section, “Rotary Switches and
LEDs,” p. 12.
Figure 3 shows how Tracer TU displays the rotary dial settings and the resulting BACnet device ID:
•
The rotary dials on the BCI-C are set to 30 (0,3,0), which is also the MAC address.
•
The Tracer SC created a BACnet device ID of 101030.
•
The Tracer SC address is “0,1,0”.
•
The BCI-C is installed on link 1.

Configuring the BCI-C
Rotary Dial Address Settings for Non-Trane SC Systems
For non-Trane SC systems, the Max Master value must be greater than the unique address settings
from the rotary dials. Although 999 is possible from the dials, the maximum allowed number by
BACnet is 127.
The Max Master is not adjustable in Trane SC systems. For example, if the MAC address is 101 and
the front-end system has a Max Master value of 100, the device will not be discovered.
Many systems have a minimum BACnet Device ID value. Ensure that the Device ID is greater than
this value.
What To Do After Adding Options or Equipment to the Unit
Restoring the BCI-C controller to factory defaults is necessary if the unit setup has changed after
the initial self-configuration process. This process is called clearing the controller.
For example, an economizer is added to the machine after the initial installation. In order for the
BCI-C controller to recognize the economizer, it must be restored to factory defaults.
The BCI-C controller self-configures upon initial power-up to match the connected equipment type.
This configuration is then permanently stored in the memory of the controller. Through this
process, the controller generates the correct list of BACnet points.
Clearing the Controller and Restoring Factory Defaults to the BCI-C
Clearing the controller is necessary to collect equipment information and reinstall the
configuration.
Using the BACnet Setup Tool to Clear the Controller and Restore to Factory
Defaults
1. Navigate to the Controller Settings screen.
2. Click within the light gray area at the bottom left of the screen just above the Connected
indicator. The Clear Controller button appears at the top right of the screen.
3. Click Clear Controller and amessage box appears stating that the configuration will be reset
(deleted).
4. Click OK. When the controller is cleared, the Select Device Units message box appears.
5. Click OK and then expand the Controller Units box on the Controller Settings screen.
6. Select the units (SI, IP, or Custom). The controller defaults to Custom after clearing the
controller. To use Custom, ensure that all unit options are set correctly.
7.
Click Save.
Using Tracer TU to Clear the Controller and Restore to Factory Defaults
1. Establish the connection between Tracer TU and the BCI-C controller.
2. Select the Controller Settings Utility tab from the vertical tab set located on the right side of the
TU window.
3. On the controller settings page, there is a gray bar at the bottom with the Save/Cancel buttons.
Move the cursor near the left edge of the gray bar, keeping the cursor inside the bar; click on
this area. A Clear Controller button will appear in the upper right portion of the screen display.
4. Click the Clear Controller button and a pop-up window will appear with a message that asks for
confirmation to reset the device. Click Yes.
5. A pop-up window will appear confirming that the controller has been reset and that the
controller will be restarted. Click OK. The BCI-C controller is restored to its factory default state
after it restarts.

BAS-SVP05E-E4 • BCI-C Integration Guide
Configuring the BCI-C
6. Follow the steps in “Using Tracer TU,” p. 8 to reconfigure the BCI-C controller.
Updating the Application Code
The application code in the BCI-C controller can be upgraded in the field by using Tracer TU. Follow
the instructions in Tracer TU to upgrade the application code.
Managing Device Units on the Controller Units Screen
The BCI-C device units can be viewed and managed on the Controller Units screen from either the
BACnet Setup Tool or Tracer TU.
When the BCI-C first powers up, or after the controller has been cleared, a list of points (the role
document) is created from the information supplied to the BCI-C from the CH530 module through
the Modbus link.
Note: The BCI-C creates the role document immediately (often within one second).
Immediately after the points are created, the device units are set and saved and appear on the
Controller Units screen. The values that correspond to the device units are set to default to SI
values. In some cases, the Custom radio button may be selected; however, the device units will still
default to SI.
Best Practice: When using Tracer TU to change the Device Units to IP by clearing the controller,
it is best to either unplug the Modbus cable to the BCI-C, or to power down the entire unit (the BCIC). By doing this, the BCI-C will not see Modbus traffic. This method will enable the Device Units
radio button selection, which allows you to make changes.

Rotary Switches and LEDs
This section provides information about the BCI-C rotary switches and LED displays.
Rotary Switches
There are three rotary switches on the front of the BCI-C device that are used to define a three-digit
address when the BCI-C is installed on a BACnet communications network. The three-digit address
setting is the BACnet MAC address.
Note: All devices are MSTP masters with valid MAC addresses of 001 to 127 for BACnet.

Object and Diagnostic Data Points and Corresponding
Chiller Models
For quick reference, the following tables are listed and sorted two different ways. Tables 3 through
8 are listed by input/output type and sorted by object identifier. These tables provide the user with
the units type for each object type. Table 9, p. 27 is sorted by object name and provides a complete
list of object names, types, values/ranges, and descriptions. Not all points are available to the user.
The available data points are defined during self-configuration and are dependent on the type of
equipment. Listed at the bottom of tables 3 through 8 are specific footnotes that correspond to
either specific chiller models or object states that are identified by a larger dot or boldface text.
Note: The last four columns in each table identifies which chiller model corresponds with each
object name.

BCI-C Alarming
The BCI-C unit has three binary input points that are used for communicating alarms and one binary
output point that is used to reset alarms remotely. Those inputs and output points are:
•
BI 23; Alarm Present– This object indicates if any alarms are active regardless of severity. A
notification will be sent to any recipients of the Information Notification Class object when the
point transitions from No Alarm to Alarm.
•
BI 24; Shutdown Alarm Present– This object indicates if any alarms that result in the
shutdown of the chiller are active. A notification will be sent to any recipients of the Critical
Notification Class object when the point transitions from No Alarm to Alarm.
•
BI 25; Last Diagnostic– The active text of this object will reflect the description of the last
diagnostic to occur on the chiller.
•
BO 2; Remote Diagnostic Reset Command– This object is used to remotely reset
diagnostics on the chiller. Immediately after commanding this point value to 1, the BCI-C will
send the reset command to the chiller and set this point value back to 0 and clear the priority
array.
Note: Not all diagnostics are able to be reset remotely. Some will require local reset at the chiller
front panel.

advocates BACnet protocol for use in system-level control
devices.
Device
A device is a standard BACnet object as defined by
ASHRAE Standard 135-2004.The Tracer UC800 contains
the BACnet object.
Device ID
The Device ID is used to uniquely identify each BACnet
Device and it can be in the range of 0 to 4194302. There
cannot be more than one device using the same Device
ID. Each of the sample applications operate as a device
and requires its own device id which defaults to zero.

Interoperability
The ability to integrate equipment from different vendors
into a comprehensive automation and control system. In
addition, digital communications between products
designed independently, but designed to the same
communication standard.
BACnet Interoperability Building Blocks
A block of BACnet application services that tells vendors
what BACnet services must be implemented to provide
specific device functionality. The BIBBs are grouped
together into BACnet device profiles.
BACnet Object
An abstract representation of the physical point or points
where data is input from or output to an I/O device. Each
object may have several BACnet properties that describe
the status of that object.
P
Protocol
A set of rules (language) that governs the exchange of
data over a digital communications system.
Baud Rate
The number of signaling elements that occur each second
during electronic data transmission. At slow speeds, baud
indicates the number of bits per second that are
transmitted. For example, 500 baud means that 500 bits
are transmitted each second (abbreviated 500 bps). At
higher speeds, multiple bits may be encoded with each
electrical change. For example, 4,800 baud may allow
9,600 bits to be sent each second. Data transmission
rates at high speeds are generally expressed in bits per
second (bps) rather than baud. For example, a 9,600 bps
modem may operate at only 2,400 baud.
