HPD0460MR Multi-Function Room Units, Modbus RTU 485
FW4.02
The HPD0460MR devices may be used as Modbus 485 networked HVAC devices or standalone; as an
HMI for control and display of multiple controllers via the field panel, 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.
The display may be programmed to indicate user specific text, data points and settable parameters
such as set-points, fan-speeds and manual overrides. The user push-buttons, indication LED’s and an
audible sounder may be independently programmed to suit the user application. Unused physical I/O
points may be used in the system independently of the control loops.
The time clock version features a 365 day clock/calendar with four channel time-switch, 20 holidays
(one-off or annually recurring) and summer/winter time.
Depending on the version, predefined logic function blocks enable easy configuration of a variety of
functions including Economy Changeover (temperature or enthalpy), VAV Volume, Hours Run
monitoring, Minutes Run monitoring, Lead/Lag changeover, instantaneous Power calculation (kW, BTU)
and a wide array of hysteresis & dead-band/live-band choices (Compare function).

Operation Overview
All physical inputs, outputs and internal logic & control function blocks, and critical control loop
parameters are numerically represented as a ‘point’. The point is a function block’s output value.
Depending on the purpose of a function block the point 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 points for network access and remote tuning of a control loop if required.
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 141101 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
 Network settings
In all cases points may be manually overridden for testing & commissioning purposes or for service
override.
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.
In the base HPD0460MR version which is without PI controller or time clock functions, the physical
inputs may be read from other controllers on the network and the outputs may be driven by other
controllers on the network. This means the HPD0460P1 may be used as a user interface to multiple
controllers in a system utilising the field panel as the router.
The HPD0460MRC, T and CT versions feature control and/or logic and/or time-switching capabilities
which enable them to work as controllers in their own right, either locally or providing control to remote
controllers and I/O expansion devices via the field panel. Note that the time switch function blocks
utilise points 101…104 therefore they must be connected to other function blocks such as Digital Logic
blocks for their status to be read by a field panel which may only read or command points from 1…99.
In all versions 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 point (or group of
points) 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.

Register Address Ranges
All points are available in three separate address ranges.
 Unsigned Integer
o Point number as represented by the function block numbers
o Typically used for digital values
o DI (Discretes) & VDI, DL, DO (Coils)
 IEEE Floating Point
o Point number x 2 + 1000
o Example: point 45 is IEEE register 1090 (45 x 2 + 1000 = 1090)
o Recommended range for any analogue values, because linearization table scaling is
automatically applied
o UI/AI, (Input Registers) & VUI, AL, CL, AO (Holding Registers)
 Priority level setting: Point number + 500
o Priority setting for point 45 is by writing to register 545 (45 + 500 = 545)
o In this register range you may read the active priority level, as well as for writing a
priority level
 Some point types may be configured as digital or analogue action and so, may have
alternative Modbus Function types available

Priority Levels
A priority level is possible for each register to enable local or master override, and setting of start-up
defaults.
 Registers are Null priority by default, signified by a value of 17, read in the 500’s register range
 Manual commands via terminal mode operate at prio. level 9 and are remembered after a
power reset if written (W) during terminal mode
 In terminal mode, Release (R) of a manual results in a register reverting to Null priority
 Commands from the network are at prio. 8
 Setting a point’s priority to a value of 0 (zero) will Write the point’s current value as the start-up
default
 Setting a point’s priority to a value from 1…7 will lock the point’s current value so that it cannot
be changed
 Setting a point’s priority to Null (17) will unlock the point so future changes to the point’s value
may be made
Example, based on point 45, used as a temperature set point:
 Change set point to a value of 22.5 °C
o 1090=22.5
o Being an analogue value we have used the IEEE Floating Point register range, based
on the formula 45 x 2 +1000 = 1090
 Write current value as a start up default
o 545=0
 Lock current value
o 545=1
 Release current value for future change
o 545=17

Interface Operation
After download of an application text-file
the HPD0460 screen may appear as in
the following example:
Press the down navigation button (D) to
scroll down to see up to 32 lines of user
display:
D
Press the up or down button to scroll through display lines. A press of the right button (R) makes cursor aligned point
available for adjustment (A) via the up and down buttons (U/D). To save the change press and hold the right button (R)
until a beep is heard. To exit adjustment mode without saving the change press the left button (L).
Exiting a set point adjustment without saving the change will result in the start up default being retained after a power
reset. If an output is being manualled via the LCD and the change is to be a start-up default then after making the
adjustment press and hold the right button until the a beep is heard. To release a M (Manualled) point back to auto
align the cursor with the point and press the left button.
