1 INTRODUCTION
1.1 Purpose
This guide describes the BACnet option for 30XA/XW chillers. It is intended for Building
Management System (BMS) engineers inside or outside the Carrier Corporation.
IMPORTANT
Some parameters can be configured only by Carrier service.
1.2 BACnet
BACnet is a data communication protocol for building automation and control networks.
It is an ISO global standard recognised in more than 30 countries across the world.
BACnet makes it possible to expand and upgrade controls using technology from different
vendors.
BACnet is based on a client-server model and BACnet messages are referred to as
"service requests". The client machine ("user interface") sends the request to the server
machine ("field device") that reports the result. For example, when the "ReadProperty"
service request is sent, the server machine locates the requested property of the
requested object and sends its reading back to the client.
1.3 Definitions, Abbreviations and Acronyms
Acronym/
Abbreviation Definition
BMS
Building Management System
It is a computer-
based control system installed in buildings. BMS
controls and monitors t
he building’s mechanical and electrical
equipment such as ventilation, lighting, power systems
, fire systems
and security systems. BMS consists of software and hardware.
BACnet/IP
Building Automation and Controls Network
Open
Protocol for the controlled exchange of data between two or
more intelligent control devices or BMS. BACnet is used over IP.
BBMD
BACnet Broadcast Management Device
Broadcast management is accomplished by defining the capabilities of
the new device.
BIBBS
BACnet Interoperability Building Blocks
BIBBS are combined to build the BACnet functional requirements for a
specific device.
COV
Change Of Value
A COV notification is sent any time the object's value changes by an
amount specified as a default pa
rameter, or in the subscription
request. Devices wishing to receive the notice of change need to
"subscribe" to the COV by sending a subscription request to the device
from which a COV notification is desired.

Additional information: BACnet/IP
BACnet/IP network is a collection of one or more IP subnetworks (IP domains)
that are assigned to a single BACnet network number.
BACnet devices are defined on the network as a collection of objects, each of which has
a set of properties defined. Two types of BACnet objects can be distinguished, i.e.
analogue and binary objects.
The most frequently referenced property for ANALOGUE /BINARY OBJECT is PRESENT VALUE,
which typically means data derived from a sensor or physical device. Other properties
associated with an object may include fault status, reliability, object name, minimum
and maximum limits, etc.
BACnet stack is an application layer that may function both as a server and a client.
The stack is the transport layer providing the following capabilities:
•The generation of limited alarm and event notifications and the ability to direct them
to recipients.
•The tracking acknowledgments of alarms from human operators.
•The adjustment of alarm parameters.
•The read/write property multiple services.
•Optional properties as COV, Intrinsic Reporting properties, Commandable properties
on some objects.
Term Definition
Device Controller/user interface or PC. The BACnet device contains a
collection of information about the device, i.e. objects and properties.
Network type Physical communication method, e.g. BACnet/IP.
Objects Information point (i.e. temperature reading, flow setpoint or
equipment schedule). The BACnet object defines certain device
information such as the device object identifier or instance number.
Every object has a collection of properties that define the object.
Note: The BACnet device object instance number must be unique
across the entire BACnet network.
Properties Information point. Properties convey information about a BACnet
object. Properties may be defined as read-only or read/write
properties.
Service Request for information or modifications (read a temperature, change
a flow setpoint, edit an equipment schedule, send an alarm). Services
defined in the BACnet network are used to take an action on objects
or properties (read-only or read/write).

2 HOW TO TRANSFORM A NON-BACNET CHILLER TO A
BACNET CHILLER
2.1 Prerequisites
The BACnet option requires the installation of the BACnet dongle. The BACnet dongle can
be mounted during manufacturing or on site.
It is strongly recommended to disconnect the main power supply before any work.
Disconnect the power supply to the chiller Touch Pilot control.
CAUTION
The power supply must be switched off before any work is begun.
Only personnel qualified in accordance with IEC 60364 recommendations (International
Electrotechnical Commission) and trained to install the BACnet option may have access to
electrical components.
The chiller controller includes electronic components that may generate or be
damaged by electromagnetic interference, e.g. Electrostatic Discharge (ESD).
ADVICE
Use an antistatic wrist strap (ESD wrist strap) when handling electrical
components. The ESD wrist strap prevents the build-up of static electricity
which may result in electrostatic discharge.
If you do not have access to an ESD wrist strap on site, please take into consideration
the following recommendations in order to reduce the risk of ESD:
Zero Potential Make sure you are at Zero Potential by touching an unpainted metal
surface of the electrical box.
Clothes Do not to wear any clothes that conduct a lot of Electrical Charge, e.g.
a wool sweater.
Accessories Remove all jewellery to reduce the risk of ESD.
Weather Electrical storms can increase the ESD risk; unless absolutely
necessary, do not to work on the chiller controller during an electrical
storm.

3 BACNET FOR 30XAXW CHILLER
The 30XAXW chiller supports the BACnet protocol as BACnet B-AAC equipment (BACnet
Advanced Application Controller).
3.1 BACnet stack
The BACnet stack includes the following options:
•COV (Change of Value), Intrinsic Reporting and Commandable properties.
•The generation of alarm notifications sent to a set of predefined recipients.
•Tracking acknowledgments of alarms raised by human operators.
•The adjustment of alarm parameters.
•Read Property Multiple services.
•Write Property Multiple services.
IMPORTANT
This option can be installed during manufacturing or on site.
3.2 BACnet settings
The BACnet option can be enabled/disabled on the Touch Pilot user interface. In order to
modify BACnet parameters, the user must be logged in at service access level.
IMPORTANT
BACnet settings can be modified only by Carrier service.
In order to enable/disable the BACnet
option, navigate to the Configuration
menu and select BACnet Parameters.
After a power up, if the BACnet dongle is detected and BACnet is enabled (BACNET ENABLE),
the chiller objects will be created (see also section 4).
Metric and imperial units are supported. By default, BACnet data is given in metric units
(METRIC UNIT =YES).

4 BACNET OBJECTS
4.1 BACnet chiller objects
The 30XAXW chiller contains up to 700 BACnet objects. These objects are of
ANALOG_VALUE (AV) or BINARY_VALUE (BV) type.
There is one Notification Class object for alarm reporting and one Device object.
Some AV and BV objects support options such as COV, Intrinsic Reporting, Commandable
properties (e.g. the Present_Value of an analog-output object). These objects are
predefined and cannot be deleted. At the same time, new objects cannot be added.
Objects names consist of the menu name (table name) and the point name.
For example:
Menu name (table name) Point name Object name
GENCONF off_on_d GENCONF_off_on_d
General Configuration Unit Off to On Delay Unit Off to On Delay
4.2 Optional properties
Change of Value is an event that occurs when a measured or calculated analogue value
changes by a predefined amount.
For the CHANGE OFVALUE option (COV) the increment value can be configured.
Intrinsic reporting is the detection and reporting of an alarm or event, based on
algorithm defined as part of the object type specification.
For the INTRINSIC REPORTING option (IR) the alarm configuration and the configuration of
the equipment to be notified are required. Otherwise, the option will not be active.
The Commandable option reflects the state of the output.
Objects with the COMMANDABLE option are named with the _wr suffix.
For example: GENUNIT_CTRL_PNT_wr (GENUNIT – General Parameters, Control Point).

BACnet Option Rev G March 2017 14 OF 56
Back to Beginning of Chapter – Table of Contents
4.3 Priority assignment
Commanding entities have their priority level assigned. The BACnet priority level
corresponds to the CCN override level.
If the Local Operating Type is set to Network, then it is possible to control the unit from
the BACnet writing these objects:
The highest priority value of the commandable object will be copied to the present
value of the object using the same name with the _rd suffix
(e.g., GENUNIT_CTRL_PNT_wr highest priority value copied to
GENUNIT_CTRL_PNT_rd present value).
If the Local Operating Type is set to Local or Remote, then the Priority value won’t be
applied and the value determined by the controller will be applied:
The present value of the object name with the _rd suffix will still reflect the
current software value (e.g., GENUNIT_CTRL_PNT_rd).
The BACnet priority level corresponds to the CCN override level (1:1). If this BACnet
priority level is removed, the first non-NULL value in Priority_array property will be
applied to the corresponding CCN point (CCN "Auto" command will be applied first). *
When the CCN override level is applied from the CCN, the CCN override level will be
the BACnet priority level.
BACnet priority level 16 (the lowest) has no CCN equivalent and does not correspond
to the CCN override. This priority level should not be used.
*The Priority_Array consists of an array of commanded values in order of decreasing priority. The first value
in the array corresponds to priority 1 (highest prority), the second value corresponds to priority 2, etc. The
sixteenth value corresponds to priority 16 (lowest prority).
4.4 Present Value property access
Writing AV and BV "Present Value" is authorized by the BACnet protocol for all objects.
However, the Present value regarding the access object parameters (read-only or
read/write) may or may not be authorised by the chiller application.
If the "present value" property with an access parameter equal to RO is written, then the
present value will be overwritten by the chiller application with the previous value.
Objects with "present value" in read-only access are all objects used for chiller
configuration and status.
Objects with "present value" in read/write access are objects used for setpoint
configuration, i.e. objects with names with the SETPOINT_ prefix (e.g., SETPOINT_csp1)
and Commandable objects with the _wr suffix (e.g., GENUNIT_CTRL_PNT_wr).
4.5 Notification class object
The notification class object can notify up to 5 BACnet devices. These devices are listed
in the Recipient List property.
IMPORTANT
You must enter the IP address of the device to notify (see also section 6).
Device Name and instance are not yet supported.
4.6 Savings
COV increment property, Intrinsic Reporting properties, Priority values, Notification class
and Trend log properties are saved in files and restored automatically on power-up.
