HPE8884MR Network I/O Expansion, Modbus RTU 485
FW4.02
28 point network point expansion unit for Modbus 485 networks. The large I/O count enables remote
monitoring and control of numerous points over the Modbus network.
Universal inputs may be locally scaled and tagged according to engineering units, calibrated and/or
filtered to adjust for cabling or sensor characteristics. Digital inputs and UI’s may be configured as pulse
counters. Digital outputs may have short-cycle timers set.
Typical Applications
 Digital/analogue inputs such as alarms, operation statuses, high/low level, water & air flow
proving, environmental conditions such as temperature, humidity or pressure, and other
auxiliary contacts.
 Digital/analogue outputs for switching of fans, pumps, lighting or remote status indication, and
modulating control of actuators, speed or load controllers and remote analogue gauges.
 Universal inputs and digital inputs may be used as counting inputs for metering of energy and
volume and instantaneous load calculation at the Master controller
Feature Summary
 8 Digital Inputs (DI n/o or n/c, flip/flop, pulse-counting up to 10Hz)
 8 Digital Outputs (DO) with power-up presetting & short-cycle timers
 8 Universal Inputs (UI - user configurable analogue [AI] or digital [DI n/o or n/c], flip/flop, pulse-

Operation Overview
The inputs and outputs are numerically represented as a Function Block ‘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.
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. Earlier versions of FuncProg may be used
but the latest feature settings will not be directly available in those earlier versions.
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
 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.

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 25 is IEEE register 1050 (45 x 2 + 1000 = 1050)
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 25 is by writing to register 525 (25 + 500 = 525)
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 25, used as a valve position:
 Change position to a value of 22%
o 1050=22
o Being an analogue value we have used the IEEE Floating Point register range, based
on the formula 25 x 2 +1000 = 1050
 Write current value as a manual override
o 525=0
 Lock current value
o 525=1
 Release current value for future change
o 525=17

Terminal Mode
The HPECOMU data cable with USB connection is used for terminal mode between the device and a
PC running a terminal program. HyperTerminal is recommended. The driver for the HPECOMU cable
may be downloaded from www.hrw.hk, Resources / Tools, section.
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:
4800

HRW HPE8884MR V402 Manual 150622.docx E. & O. E. / Subject to change without notice Page 8 of 24
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)
Changing Baud Rate
After changing to a new baud rate the controller will not start running at the new baud rate until the
change has been Written (W). If setting a new baud rate via text file application download the new baud
rate will be applied immediately the download is completed (auto-Write).
In either case, after the Write action, you will need to reconnect the terminal program at the new baud
rate if you wish to continue the terminal session.

HRW HPE8884MR V402 Manual 150622.docx E. & O. E. / Subject to change without notice Page 9 of 24
Break in to Terminal Mode
When HyperTerminal is running and the HPECOM cable is connected to the powered device the initial
terminal screen will be blank. If the device power is reset “Hello” will appear on the screen. If Hello does
not appear on the screen after a power reset then it is likely that the HyperTerminal baud rate setting is
incorrect.
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 device will display the default user screen.
