Introduction
The 32MP Gateway is a component of the Carrier Comfort Network
(CCN) CHILLERVISOR system. The 32MP Gateway integrates a
centrifugal chiller into the Carrier Comfort Network (CCN). The
chiller must be equipped with a 3200MP Controller and an ESP-II
Expanded Services Panel. The 32MP Gateway can be used with both
single and dual compressor chillers. A single 32MP Gateway provides interface functions for one chiller.
A CCN Building Supervisor communicating through a 32MP Gateway can be used to configure certain ESP-II and 3200MP Controller
parameters, and to display current operating conditions of the chiller
connected to them. The Building Supervisor also annunciates alarms
and displays alarm messages generated by the 32MP Gateway.
BEST, Carrier’s custom programming language, can access points
and decisions in a 32MP Gateway. BEST programs, which reside in
a FID, can read data from 32MP Gateway parameters displayed on
the points, service configuration, configuration, and maintenance
screens.
32MP Gateway
Hardware
The 32MP Gateway is a CCN CIO (Communications Input/Output)
Module equipped with specialized software that enables it to perform
its interface functions. The 32MP Gateway is shown in Figure 1.
COMM1 is the 32MP Gateway’s connection to the CCN Communication Bus. The bus can operate at 1200, 2400, 4800, or 9600 bits
per second (bps). It typically operates at 9600 bps. A 32MP Gateway can reside on any CCN Communication Bus, 0-239, and can be
assigned any system element number, 1-239. The 32MP Gateway’s
default address is Bus 0, System Element 85.
COMM2 is the Gateway’s connection to the 3200MP Controller
Communication Bus. The 3200MP Controller Communication Bus
operates at 1200 bps. For this reason, COMM2 also operates at 1200
bps.
2
The Network Configuration Tool (NCT) may be used to change the
32MP Gateway’s bus and system element numbers and the baud rate
of COMM1 if necessary.

32MP Gateway
Functions
The 32MP Gateway’s primary function is to integrate a centrifugal
chiller equipped with a 3200MP Controller and an ESP-II panel into
the Carrier Comfort Network II. Other 32MP Gateway functions
include:
•
•
•
•
•
•
Program enable/disable
Elapsed on-time tracking
Remote Contacts Start/Stop
Shutdown and communication alarms
BEST program access
CHILLERVISOR System Manager (CSM) support
Each function is described in detail below.
Program Enable/
Disable
On initial power up, the 32MP Gateway automatically determines
whether it is connected to a single or dual compressor chiller.
Because of this, a Building Supervisor cannot display 32MP Gateway data if the gateway is not connected to a functional 3200MP
Controller Communication Bus.
Two switches on the 3200MP Controller allow the user to enable
and disable the 32MP Gateway manually. The two switches are the
Local/Remote switch on the 3200MP’s Setpoint/Display Board, and
the Panel/Remote switch on the ESP-II panel. The 32MP
Gateway’s ability to write to the 3200MP/ESP-II software is disabled when either switch is not in the Remote position. If the
switches are in the Local or Panel modes, chiller parameters can be
displayed, but configuration changes cannot be made.
4
Elapsed On-time
Tracking
The 32MP Gateway accumulates up to 32,767 hours of elapsed ontime for its chiller. The accumulated on-time value is displayed on
the Building Supervisor’s points screen, and may be modified by an
operator using the Building Supervisor.
Remote Contact
Start/Stop
The 32MP Gateway and the ESP-II panel each include a remote
contact option that, when enabled, allows the chiller to be stopped
and started by contact closure input from a field-installed remote
start relay. Because the gateway supercedes the ESP-II panel in
initiating the chiller's starts and stops, it automatically disables the
panel's remote contacts option. The panel's option can be enabled,
but it will be disabled by the gateway as soon as the panel is returned to remote mode. Because of this, when enabling, disabling,
or checking the status of the remote contact option the user should
do so at the 32MP Gateway, not at the ESP-II panel.
Shutdown and
Communication Alarms
The 32MP Gateway generates two types of alarms. A CHILFAIL
alarm is generated if a 3200MP Controller shutdown fault occurs.
The 3200MP status code is included in this alarm message. A
CHILCOMM communication error alarm is generated in the event
of a communication failure between the 32MP Gateway and the
3200MP Controller/ESP-II. If the communication failure is with the
3200MP within the chiller or with the cable from the chiller to the
32MP Gateway, a code value of 1 is included with this alarm message. If the communication failure is with the ESP-II within the
chiller, a code value of 2 is included with this alarm message.
When alarms occur, they are annunciated at the Building Supervisor
and the alarm messages are placed into its alarm file.
BEST Program Access
BEST programs, which reside in a FID, can access 32MP Gateway
points and decisions. BEST can read data from 32MP Gateway
parameters displayed on the points, service configuration, configuration, and maintenance screens through the appropriate tables. BEST
IV can write data only to those points that are accessible by the Data
Transfer function. To see the list of point names that are accessible
by Data Transfer, refer to Table #1 on Page 9.
CHILLERVISOR System
Manager Support
The CHILLERVISOR System Manager (CSM) is a device that
coordinates chillers equipped with 32MP Gateways. It can coordinate the operation of up to eight centrifugal chillers. The 32MP
Gateway contains a dedicated internal data structure that can be
accessed by the CSM. For specific information regarding the CSM,
refer to the CSM Overview and Configuration Manual (808-625).
Operator
Interface
The Building Supervisor is the primary operator interface to the
32MP Gateway. Once a 32MP Gateway is connected to a 3200MP
Controller Communication Bus and a CCN Communication Bus, an
operator at a Building Supervisor can add it to the Carrier Controls
List and upload the data from the 32MP Gateway to the Building
Supervisor’s database.
5
An operator working at a Building Supervisor can then:
•
display a list of 32MP Gateway points that shows current conditions at the chiller and the last five shutdown codes.
•
modify selected points and return them to local control.
•
display configuration and maintenance screens and change
3200MP Controller configuration data.
•
create graphics.
There are eight screens associated with the 32MP Gateway:
•
•
•
•
•
•
•
•
Points screen
Service configuration screen
Configuration screen (CONFIG1)
Maintenance screen
Alarm configuration screen (ALRM-CFG)
Runtime Equipment Part Configuration screen (RUN-POC1)
Consumable Equipment Part Configuration screen (CONSPOC1)
Controller Identification screen (CTLR-ID)
The Points screen displays the current status of chiller parameters
such as status codes, setpoints, and operating temperatures. The
status of selected points can be modified by the operator using the
Building Supervisor’s Force function. The force can be removed
using the Auto function. Note that the Auto function removes only
the SUPVSR force message from the Building Supervisor screen.
The value entered remains in effect at the 3200MP/ ESP-II. From
the Points screen, an operator can modify the values of the following points:
•
•
•
•
•
6
Chiller Start/Stop
Leaving Chilled Water (LCW) Control Point
Demand Limit
Compressor On-time
Remote Contact Input
Note:
Due to the nature of communications between the 32MP
Gateway and the 3200MP Controller/ESP-II combination,
it can take up to thirty seconds for the modified value to
be displayed on the Building Supervisor screen.
The Service configuration screen displays service parameters read
by the 32MP Gateway from the configuration (DIP) switches located on the 3200MP Controller. Service parameters include machine, starter, and sensor types.
The Configuration screen allows an operator to enter data used by
the 3200MP’s reset, restart, and remote contacts options. The table
named CONFIG1 is selected to display this screen.
The Maintenance screen displays the current status of the 3200MP
Controller’s inputs and outputs.
The Alarm configuration screen is displayed by selecting the table
named ALRM-CFG. This screen is a listing of 32MP Gateway
alarm configuration decisions such as Alarm System Name and ReAlarm Time.
Specific information on each item displayed on the Points, Service
Configuration, Configuration, Maintenance, and Alarm Configuration screens is provided in the Configuration section beginning on
Page 11.
The Runtime and Consumable Equipment Part Configuration
screens are displayed by selecting the tables named RUN-POC1 and
CONS-POC1. If 32MP Gateway points are to be used in conjunction with the Runtime and Consumable supervisory parts of a CCN
Data Collection Option, this is where the point names and types of
those points are entered. See Page 8 for more information on Data
Collection.
The Controller Identification screen lists 32MP Gateway controller
parameters such as device name, description and location, and
software and assembly part numbers. The table named CTLR-ID is
selected to display this screen.
7
The 32MP Gateway can display units in either imperial or metric
format when used with the Building Supervisor III. Data from
gateways used with the Building Supervisor II can be displayed in
imperial units only.
Network Functions
The CCN network functions that are relevant to a 32MP Gateway
are the Data Collection and Data Transfer Options, and BEST
programs.
Data Collection
The CCN Data Collection Option can be used to collect data from
the 32MP Gateway points listed in Table 1.
Points must be specified by name and type when configuring the
Data Collection Option’s supervisory part. Consumable and Runtime point names and types must also be configured in the 32MP
Gateway’s equipment parts (CONS-POC1 and RUN-POC1).
For more information on the Data Collection Option, refer to the
Data Collection Option Overview and Configuration Manual (808556). Consumable and Runtime equipment part configuration
sheets can also be found in that manual.
Data Transfer
The CCN Data Transfer Option can be used to transfer data from or
to the 32MP Gateway points listed in Table 1.
To transfer data from the 32MP Gateway, the point names given in
Table 1 must be configured in the Source Variable Name decisions
at the Data Transfer Option.
These point names must also be used when transferring data to the
Gateway. A data transfer to a point results in a controller force on
that point. For this reason, it is recommended that caution be used
when transferring data to the 32MP Gateway. Data should not be
transferred to the spare sensor points.
For more information on the Data Collection Option, refer to the
Data Transfer Option Overview and Configuration Manual (808557).

BEST programs, which reside in a FID, can access 32MP Gateway
points and decisions. BEST can read data from 32MP Gateway
parameters displayed on the points, service configuration, configuration, and maintenance screens.
Each item displayed is indexed by a table number corresponding to
the screen on which it appears, and by point or decision number.
Section 3 of this manual contains a complete list of table, point, and
decision numbers.
Note:
With the exception of the points listed in Table 1 above,
the points listed in Section 3 can only be accessed by table
and index number.
In BEST programs the CONNECT statement is used to access
32MP Gateway parameters. Use the following format to read any
32MP Gateway point or decision:
CONNECT var AS A DECISION TO table, index IN number
where var is a user-defined name for the point or decision.
table is a number corresponding to the 32MP Gateway
screen on which the point or decision appears.
index is a number corresponding to the 32MP Gateway point
or decision.
9
number is a 32MP Gateway’s system element number on a
CCN Communication Bus.
BEST IV can write data to only those points that are accessible to
the Data Transfer function. To see the list of point names that Data
Transfer can access, refer to Table 1 on Page 9.
When using BEST IV to write to points, use this statement format to
connect to variables:
CONNECT var AS A type TO point IN element USING SAFETY LIMITS low, high
Note:
The format shown above can only be used for the points
listed in Table 1. All other points must use the format
shown on the previous page. Remember that the other
points can only be read by BEST, not written to by BEST.
For more information on BEST, refer to the CCN BEST IV Programmer's Reference Manual (808-699).

Points Screen
The Points menu item is used to select the Points screen. The Points
screen displays current conditions at the chiller and the last five
shutdown codes.
The Building Supervisor or Service Tool’s force operation can be
used to modify the values of selected 32MP Gateway points.
Transmitting a force command to one of these points causes its value
to change and the SUPVSR force message to be displayed on screen
with the point.
Using the Auto operation removes the SUPVSR force message from
the screen. The point does not return to the value it had before being
forced. Of the 32MP Gateway points that can be modified, only
Compressor On-time displays a dynamic value. The other modifiable
points only change their values when commanded to. The commands
can come from an operator, or from other devices on the CCN, such
as CHILLERVISOR System Manager, Data Transfer, or BEST IV.

Reference: 3200MP Expanded Services Panel Start-up, Operation,

The 32MP Gateway and the ESP-II panel each include a remote
contacts option that, when enabled, allows the chiller to be stopped
39
and started by contact closure input from a field-installed remote
start relay. Because the gateway supercedes the ESP-II panel in
initiating the chiller's starts and stops, it automatically disables the
panel's remote contacts option. The panel's option can be enabled,
but it will be disabled by the gateway as soon as the panel is returned to remote mode. Because of that, when enabling, disabling,
or checking the status of the remote contacts option the user should
do so at the 32MP Gateway, not at the ESP-II panel.

Screen
The alarm configuration screen is displayed by the operator at a
Building Supervisor to configure alarm parameters such as system
names and re-alarm times. The table named ALARM-CFG is selected to display this screen.
The alarm configuration screen is shown in Figure 10. Specific
decision information follows.
Alarm Control
This decision defines the CCN system elements that will process
32MP Gateway alarms.

Priority
This is used to define the priority of 32MP Gateway alarms. A
priority of 0 is the highest priority and a priority of 7 is the lowest
priority.
A priority of 4 is reserved for chiller alarms. It is therefore recommended that you do not change the value of this decision.
Allowable Entries
Communication Failure
Retry Time
This decision defines the interval between alarm retries. If an alarm
sent by the 32MP Gateway is not acknowledged by a network alarm
acknowledger, the same alarm will be sent again following the
amount of time entered in this decision.
Allowable Entries
Re-alarm Time
1 to 240 minutes
This is the interval between re-alarms sent by the 32MP Gateway.
As long as the alarm condition that initially caused an alarm exists,
the 32MP Gateway will continue to retransmit the alarm at regular
intervals. The interval between retransmissions is the amount of
time entered in this decision. Re-alarming will stop when the alarm
condition returns to normal.
Allowable Entries
Alarm System Name
0 to 7 priority numbers
1 to 255 minutes
This decision is used to identify the system element generating an
alarm. In the case of the 32MP Gateway, the default name
32MPGTWY will appear in the alarm message displayed at Building Supervisors. In a multiple chiller system this name can be
changed to identify the gateway serving each individual chiller.
32MPGW-1 and 32MPGW-2 might be used, for example.
Allowable Entries
Up to 8 alphanumeric characters
