HPD0440BNMR Controller, Logger, Gateway
BACnet MS/TP with Modbus RTU integration
FW4.01
The HPD0440BNMR may be used as a BACnet networked HVAC device or standalone; as an HMI for
control and display of multiple controllers on a local network, as a controller with high flexibility for user
configuration to suit a wide variety of control applications or as a network manager including multi-zone
annual time scheduling.
Two key features of this device:
32 register Modbus RTU 485 gateway port to allow Modbus device data to be gathered for
display, used in control applications and/or for network integration in to the wider BACnet
system
Eight channel data logger for local retrieval of user selected operating parameter history.
Logger channels may be individually started/stopped by local or network events (clock
schedule, function block output state, remote network object state via NIO)
The display is programmable to indicate user specific text and dynamic data points. Data points may be
adjusted directly at the LCD (parameters such as set-points, fan-speeds and manual overrides). The
text and dynamic values for each of the 32 user lines may be set as small font size or large font size.
The user push-buttons, indication LED’s and an audible sounder may be independently programmed to
suit the user application. Physical I/O points may be used in the system independently or, subject to the
version, by the internal control loops and logic blocks.
Predefined logic function blocks enable easy configuration of a variety of functions including Economy
Changeover (temperature or enthalpy), VAV Volume, Hours Run monitoring, Lead/Lag changeover and
instantaneous Power calculation (kW, BTU).
The time clock features a 365 day clock/calendar with four channel time-switch, 20 holidays (one-off or
annually recurring) and summer/winter time.
Typical Applications
Temperature, humidity, pressure, IAQ, universal
On/off, 3-point modulating, PWM (Pulse Width Modulation), step control, DX
Equipment and space monitoring (chillers, AHU’s, controlled environments)
Local User Interface, network interface, networked or standalone controller
Modbus RTU master / gateway for BACnet
Time-clock & calendar / time-switch, networked or standalone

Operation Overview
All physical inputs, outputs and internal logic & control function blocks, and critical control loop
parameters are numerically represented as an ‘Object’. The object is a function block’s output value.
Depending on the purpose of a function block the object may have a range of sub-parameters available
for defining the block’s function and the operational features & limitations of the function. In the case of
control loops the active set point, the proportional band and the integral time sub-parameters are also
represented as objects for network access and remote tuning of a control loop if required.
In this document the term ‘Objects’ will mainly be used in the context of BACnet networks but will
otherwise be referred to as a ‘point’ or ‘points’ when discussing specific control applications.
The process of setting up function blocks and connecting function blocks to form an application uses
simple text lines therefore it is not necessary to learn a complex programming language. The settings
may be manually typed in to the device or, using the FUNCPROG 110601 programming tool which
provides a visual representation of each block, an application text file may be created, saved and
downloaded to the device as a complete group of settings.
The ability to make single setting changes directly at the device makes for easy debugging and
commissioning.
The function blocks comprise:
Physical I/O for connection of input switches, sensors and output control devices
Virtual inputs for taking over external commands and values from other network devices or for
manual settings and overrides
Logic blocks for event based reactions and influences
PI Control Loop blocks for set point based control reactions
In all cases points may be manually overridden for testing & commissioning purposes or for service
override. In respect of BACnet priority arrays manual overrides are Priority 9 (factory default = Null /
internal program control = 16).
Connection to the device for programming and service is via a terminal program such as HyperTerminal
(recommended). While on-line to the device it is possible to view point statuses and where applicable,
any dependent or influencing point’s connections. Statuses are updated live to the terminal screen
every 10 seconds or manually refreshed any time by pressing the enter key.
In additional to the predefined point displays a user-defined display is available for a customised point
summary related to an application. The user display may contain up to 32 lines of user text with or
without dynamic points included.
The user has the freedom to specify own display text in up to 32 lines with or without dynamic object
displays. Text lines may be programmed to be invisible until a specific object (or group of objects) met a
predefined criteria at which time the text will ‘pop-up’ at the top of the display. When the predefined
criteria is no longer true then the text will no longer be displayed. This feature is designed for use as
alarm indication and can be used together with the programmable LED’s and audible beeper to raise
attention to an alarm situation.

HRW HPD0440BNMR V401 Manual 111116.doc E. & O. E. / Subject to change without notice Page 6 of 43
BACnet Object Instances
Up to 110 function blocks exist in the device depending on the version. Because many objects may be
Binary or Analogue, and may be seen as an Input, an Output or a Value, the final total of discoverable
and device relevant object instances may be up to 124.
A physical universal input (UI) may be an AI (Analogue Input) or AV (Analogue Value) but
when used as a digital input then it’s object instance would be a BV (Binary Value)
A Virtual Universal Input (VUI) is seen as an AV (Analogue Value)
A physical digital output is a BO (Binary Output) by default but if programmed for PWM control,
which has a control value of 0…100%, then it is seen as an AV (Analogue Value)
Using UI3 as an example:
Description: Physical universal input
Object #: 19
Object Instance when binary DI: BV19
Object Instance when analogue sensor: AI19 or AV19
Using AL1 as an example:
Description: Analogue Logic block
Object #: 53
Object Instance when Digital function: BV53
Object Instance when Analogue function: AV53
The common reference in all cases is the object # therefore during device Object Discovery over the
network the option of Input, Output or Value is decided based on the programmed application use of the
object in question.
BACnet Priority Array
The BACnet protocol utilises a Priority Array for each object to enable various network devices to take
control of a device’s object based on the level of need. Priority 16 is the least significant level and may
be considered normal ‘Auto’ operating level. Priority 1 is the highest control level, generally used for
emergency control under fire condition or similar events.
In respect of this device:
The objects are null priority by default
Commands from the internal control program of the device are at priority level 16
Manual commands via terminal mode operate at priority level 9
Release of a manual results in an object reverting to next lowest and still valid priority level
Commands from the network to DO, AO, VUI and VDI objects are remembered after a power
reset if priority 1…8
Commands from the network to Proportion Band & Integral Time points of Control Loops are
written to those objects if other than null priority

Output Minimum when applied to an Output OR and Output Maximum when applied to an Output AND.
LED 3 & 4 and the audible beeper have a fixed 5sec PWM cycle time with 1sec resolution. Therefore
if digital 1 or 100% is applied then the LED/beeper will be on continuously. If 60% applied then the
LED/beeper will be on for 3sec, off 2sec, on 3sec, and so on. The minimum applied value for an output
reaction is 20% (1sec on, 4sec off). In HPD0460BN these outputs may be driven by peer-to-peer
controllers on the network or via the internal NIO’s reading in object values from other controllers on the
network. HPD0460BNC, T or CT can control objects 25…27 directly using their own internal function
blocks.

Terminal Mode
The HPECOM serial data cable is used for terminal mode between the device and a PC running a
terminal program. HyperTerminal is recommended. A USB port <> Serial comm port (DB9) converter
may be required if the PC being used does not include a Com 1 serial port.
HyperTerminal Settings
For successful communication between HyperTerminal and the device, initial Properties setup of
HyperTerminal should be as per the screen prints below.
‘Connect to’ Comm Configuration: ‘Settings’ General:
‘Settings’ ASCII Setup:
9600

HRW HPD0440BNMR V401 Manual 111116.doc E. & O. E. / Subject to change without notice Page 16 of 43
Additional Settings
Some PC platforms may need keyboard response adjustment for initial Terminal Mode success. These
settings may be done via the PC Control Panel >> Keyboard Settings:
Fastest Repeat rate
Shortest Delay time
Fastest Cursor Blink rate
Connecting at 76800 Baud Rate
Because HyperTerminal does not support 76800 baud then after setting to 76800 the device baud rate
will remain at 9600 baud for HyperTerminal communication and switch to 76800 after Writing the new
baud rate and eXiting terminal mode.
To allow later terminal communication a device set with 76800 baud will operate at 9600 baud for the
first 5 seconds after a power-up. If no attempt to connect the terminal at 9600 baud is made within 5
seconds of a power-up then the device will automatically switch to 76800 for normal network operation.
Saving HyperTerminal Settings
For ease of connection it is recommended to save the HyperTerminal setup for each baud rate you may
wish to use with an easily recognised configuration name. For example:
HPECOM 24 (2400)
HPECOM 48 (4800)
HPECOM 96 (9600)
HPECOM 19.2 (19200)
HPECOM 38.4 (38400)
HPECOM 57.6 (57600)
Break in to Terminal Mode
When HyperTerminal is running and the HPECOM cable is connected to the device the initial terminal
screen will be receiving an ASCII character dump which is the BACnet transmission from the device.
The ASCII dump will appear differently with different device address setting and if HyperTerminal baud
rate is different to the baud rate set in the device. Below is an illustration of how the ASCII dump will
look for a device at default settings; address 98 and 9600 baud.
To break in to terminal mode set Caps Lock on and hold the ‘T’ character key continuously
(TTTTTTT…). After five (5) T’s have been sent to the device it will switch to terminal mode. At this point
the BACnet activity on the network will be halted and the device will display the default user screen.

value. The BACnet priority level = 9
Manualled physical inputs (points 1…4 & 17…20) will revert to ‘Auto’ after being Released or after a
power reset. Physical outputs will retain the Manual setting after a power reset if the Manual state is
Written (W) before being released, thereby making the Manual state the power-up default state.
