The X-IRI Communication Gateway is designed to
in
terface the Intellisys Controllers on Ingersoll Rand
Compressors with a Distributed Control System (DCS),
Programmable Logic Controller (PLC), or any other
device that is capable of communicating using the
MODBUS RTU communications protocol.
SECTION 3 SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
The X-IRI provides MODBUS connectivity to Ingersoll
Rand controllers that do not have built-in MODBUS
capability. The X-IRI also provides address filtering and
communication buffering capabilities to protect the
integrity of the serial data network.
The X-IRI is designed to be DIN Rail mounted within the
compressor control gear enclosure but can alternatively
be mounted remotely within a separate enclosure.
3
MAINTENANCE AND REPAIR
M
aintenance, repairs or modifications must only
•
be carried out by competent personnel under
qualified supervision.
If replacement parts are required, use only genuine
•
parts from the original equipment manufacturer, or
an alternative approved source.
Carry out the following operations before opening
•
or removing any access panels or carrying out any
work on the X-IRI GATEWAY:
Isolate the X-IRI GATEWAY from the main
i.
electrical power supply. Lock the isolator in the
“OFF” position and remove the fuses.
Attach label to the isolator switch and to the
ii.
unit stating “WORK IN PROGRESS - DO NOT
APPLY VOLTAGE”. Do not switch on electrical
power or attempt to start the X-IRI GATEWAY if
such a warning label is attached.
Make sure that all instructions concerning
•
operation and maintenance are strictly followed
and that the complete unit, with all accessories and
safety devices, is kept in good working order.
The accuracy of sensor devices must be checked
•
on a regular basis. They must be calibrated when
acceptable tolerances are exceeded. Always ensure
any pressure within the compressed air system is
safely vented to atmosphere before attempting to
remove or install a sensor device.
•
The X-IRI GATEWAY must only be cleaned with a
damp cloth, using mild detergents if necessary.
Avoid the use of any substances containing
corrosive acids or alkalis.
Do not paint the control faceplate or obscure any
•
indicators, controls, instructions or warnings.

SECTION 4 COMPRESSOR CONNECTION AND CONTROL
Setting a MODBUS polling rate of less than 500
milliseconds will not cause a quicker response from X-IRI.
The PLC or DCS communicates to the X-IRI Gateway via
a two wire, RS-485 network utilizing the MODBUS RTU
protocol.
The X-IRI Gateway module is installed within the
compressor control cabinet and connected to the PLC or
DCS using Belden 9841 or equivalent RS-485 cable.
INTELLISYS SOFTWARE REQUIREMENTS
Each Intellisys controller must have its controller
software revision at or above a certain minimum level
to work with the IRI.
The machine types and required software EPROM
minimum version levels are listed below. Check the
machine to be connected to an IRI for the appropriate
EPROM. If the EPROM is not of the correct minimum
version level, the appropriate EPROM may be ordered
from your local Ingersoll Rand Distributor or Air Center.
Machine Type EPROM Minimum Version Level
SSR 50-450 Horsepower - 1 stage (Red Eye) 2.3
SSR 50-450 Horsepower - 2 stage (Red Eye) 2.3
SSR SG 1.0
15-50 Horsepower 1.4
Sierra 50-100 Horsepower (SE) 1.2
Sierra 100-200 Horsepower (Red Eye) 2.5
Sierra 125-400 HP SG 1.0

Pegasus 1.0
ESA SE 22-150 KW 1.6
When monitoring compressor data only, no options
are required to be installed in the Intellisys controller. If
machine control is desired, the Remote Start/Stop and
Sequence options must be installed and turned “On”.
COMPRESSOR CONNECTION AND CONTROL
T
he X-IRI Gateway module is designed to interface to
any Ingersoll Rand Intellisys controlled compressor. All
Ingersoll Rand compressors equipped with Intellisys
controllers must use this interface when communicating
with MODBUS masters.
The X-IRI gateway prevents the compressor controller
from seeing any communications that aren’t directed
toward the controller’s network address. Additionally, the
X-IRI will buffer communications so that the compressor
controller will not receive a command greater than once
every 500 milliseconds.

MODBUS RTU
A pause longer than 1.5 byte-times will render the
message invalid and it will be ignored.
Message data format is dependent on function and will
consist of a combination of the following elements:
1) Destination address (slave network address)
2) Function Code
3) Data start address (slave register start address)
4) Number of registers, number of bytes of data
5) Message data
6) CRC checksum
Message Destination Address
The ‘destination address’ must be correct for the ‘slave’
controller device for which the message is intended. An
address can be from 1 to 127 decimal (01Hex to 7FHex).
The SMG Box is transparent and addresses must be for the
destination ‘slave’ controller or unit. Each controller or unit
must be set with a unique address.

Message Function Codes
The message function code defines the required data
processing operation of the slave controller. Although
several types of message function codes are defined by
the MODBUS standard, only the message function code
types working directly with registers are implemented on
controller units:

an EXCEPTION response.
This document discusses generic MODBUS
communications and how to implement the software
specific ‘MODBUS Table’ information. MODBUS
communication formatting may differ from controller to
controller and you may require more than one ‘MODBUS
Table’.
Always check the software variant identification and
version number for a controller with the variant and
version of the ‘MODBUS Table’ supplied. In some instances
the information contained in a ‘MODBUS Table’ may not
be applicable to a controller installed with the same
software variant but a different version number.
General
MODBUS RTU (Remote Terminal Unit) is a master-slave
type protocol. An Intellisys Controller functions as the
slave device. Information requests or commands are
communicated from master to slave only through the
X-IRI.
The X-IRI will always respond to communications from a
remote master device in accordance with the MODBUS
RTU protocol standard.
The MODBUS protocol is used to communicate with
personal computers (PC), Programmable Logic Controllers
(PLC’s), or Distributed Control Systems (DCS) over the
Network port. The X-IRI only responds to two MODBUS
commands, Read Holding Register 03 (03 Hex) and Preset
Single Register 06 (06 Hex). (See Modicon MODBUS
Protocol Reference Guide, PI-MBUS-300 Rev. J or later, for
more details on MODBUS).
Communication Link
MODBUS is implemented using a two-wire RS485
industry standard communications link operating in
master-slave mode.
RS485 Serial Data Format
The RS485 MODBUS port is a 2-wire operating with an
asynchronous serial data format: 8 data bits / no parity / 1
or 2 stop bits (8,N,1 or 8,N,2) - transmitted at 9600 baud.
Message Data Format
The bytes of the MODBUS RTU message must be sent
in one message package. The RTU protocol allows for a
maximum pause of 1.5 byte-times between 2 consecutive
bytes of a message.

Message Data
The message data content depends on the message
function code type.
03H Read Holding Register(s)
The Number of Registers designates the 16bit integer
value that determines the size (in 16bit ‘word’ registers)
of the message data being requested. This is the number
of 16bit registers to read. This information is contained in
the ‘MODBUS Table’.
A maximum of 32 registers can be read at one time.

The CRC (Cyclical Redundancy Check) is a check-sum
generated by means of ‘A001H polynomial’.
Slave
Address
Function
Code

Address
DATA
byte 0 byte 1
CRC Check
Sum
22 06 00 6F 00 5F FE BC
The CRC is two bytes containing a 16-bit binary value
(word). The CRC value is calculated by the transmitting
device that appends the CRC to the end of the message.
The receiving device recalculates the CRC value prior
to processing of a received message and compares the
result to the actual CRC value appended to the message.
If the two values do not match the message is regarded
as invalid.
The CRC is initiated by first preloading a 16bit register
to all 1’s (FFFF Hex). Then a process begins of applying
each consecutive 8bit byte of the message to the register
contents using an exclusive ‘OR’ calculation. The result is
shifted one bit in the direction of the least significant bit
(LSB), with the most significant bit (MSB) set at ‘0’. The LSB
is then examined; if ‘1’ the register content is applied to
the polynomial value ‘A001’ Hex (1010 0000 0000 0001)
using an exclusive ‘OR’ calculation - if ‘0’ no exclusive OR
takes place.
This process is repeated until eight ‘bit’ shifts have
been performed. After the eighth bit shift, the next 8bit
message byte is applied to the register contents using an
exclusive ‘OR’ calculation. The bit shift and re-calculation
process is then repeated again. When all message bytes
have been processed the final content of the 16bit
register is the message CRC value.
Only the 8bits of ‘data’ in each message character is used
for generating the CRC; start, stop and parity bits are
ignored.
When the 16bit CRC value is appended to a message,
the low order byte must be transmitted first followed by
the high order byte. An incorrect or byte reversed check
sum will render the message invalid and it will be ignored.
Slave Response Timeout
A slave controller may not answer immediately. Ensure
the ‘slave timeout’ setting of the ‘master’ device is set
to a value no less than 500ms. If the ‘slave’ device fails
to receive a valid message due to a communication
disruption, parity error, CRC error or other reasons, no
response is given and the master must process a timeout
condition in this instance. If the ‘slave’ receives a valid
message that cannot be processed an exception response
will be returned.
T
he message data start address (16bit word) designates
the initial register address location in the controller from
which the data is processed. Start address information is
contained in the ‘MODBUS Table’.

Exception Response
If the ‘slave’ device receives a request that cannot be
processed an ‘exception response’ is given. An exception
response message consists of the following elements:
Slave Network Address (1 byte): Slave address
identification
Function Code (1 byte): In a normal response, the
slave repeats the function code of the original
master request. All function codes have an MSB
(most significant bit) of 0 (values are all below 80
hexadecimal). In an exception response, the slave
sets the MSB of the function ‘code’ to 1. This makes
the ‘code’ value 80 Hex greater than the received
‘code’ value from the master.
Data (1 byte): The ‘data’ response will contain a ‘1
byte’ value exception code.
CRC Checksum (2 byte).

Troubleshooting
Problem:
No ‘slave’ response or corrupt MODBUS message
Solution:
Check that the ‘slave’ controller is set for the
anticipated slave address
Check that all ‘slave’ controllers are set with a unique
system address
Check that the controller is set for MODBUS RTU
mode (if applicable)
Check that the ‘master’ is operating in MODBUS RTU
mode
Check that the ‘master’ baud rate, parity bit and
number of stop bits are correct
Check that the ‘master ‘response timeout is set for a
minimum of 500ms
Check that the ‘master’ is implementing the specified
CRC check sum process
Check RS485 wiring polarity and security of
connections
Problem:
Last character of MODBUS message is corrupted
Solution:
Add a delay of 2ms after last character received
before releasing RTS signal
Problem:
The MODBUS master message is reflected in the
slave answer
Solution:
Inhibit RX/TX echo on ‘master’ device
communications port

T
he format of the ‘slave’ controller answer is similar to the
original master request format; the message data content
depends on the message function code type.
The ‘address’ and ‘code’ of the slave answer is identical
to the original request message; the address is the ‘slave’
device address and the ‘code’ is a repeat of received
function code type from the master. The remainder of the
message is dependent on the requested function code
type. The CRC checksum is re-calculated for the answer
message characters using the specified CRC process.

RS485 NETWORK
RS-485 data communications and other low
voltage signals can be subject to electrical interference.
This potential can result in intermittent malfunction
or anomaly that is difficult to diagnose. To avoid this
possibility always use earth shielded cables, securely
bonded to a known good earth at one end. In addition,
give careful consideration to cable routing during
installation.
1) Never route an RS-485 data communications or low
voltage signal cable alongside a high voltage 3-phase
power supply cable. If it is necessary to cross the path of a
power supply cable(s), always cross at a right angle.
2) If it is necessary to follow the route of power supply
cables for a short distance (for example: from a
compressor unit to a wall along a suspended cable tray)
attach the RS- 485 or signal cable on the outside of an
earthed cable tray such that the cable tray forms an

3) Where possible, never route an RS-485 or signal cable
near to equipment or devices that may be a source of
electrical interference (for example: 3-phase power
supply transformer, high voltage switchgear unit,
frequency inverter drive module, radio communications
antenna).

MODBUS ADDRESS SELECTION
Each compressor connected to the MODBUS network will
have a unique assigned address, starting at compressor
1 increasing sequentially to the number of compressors
connected to the MODBUS network. The MODBUS
address is selected by using DIP switches 1, 2, 3, and 4
on SW1, and switches 1, 2, and 3 on SW2 on the X-IRI
Gateway.
SW1, 1 to4 and SW2, 1 to 3: Address Selection
The addresses are selected as shown in the following
table: (Note: ON = 1, OFF = 0 )

MODBUS PORT SETUP SELECTION
SW1 SW2
SW3
The MODBUS port setup is determined by means of DIP
switch 4 on SW2 and DIP switches 2,3 and 4 on SW3. The
selectable items are: baudrate and number of stop bits.
Parity is not selectable and fixed at “no parity”
SW2-4: Stop Bit Selection
1 stop bit
2 stop bits
SW3-2...4: Baudrate Selection
1200 baud 2400 baud

When DIP Switch 1 on SW3 is set to the ‘on’ possition the
LED indicators (LED 2 to 9) will show the software version:

To establish the software version number (01 to 255) add
together the ‘value’ associated with each illuminated LED.
LED # Value
6 =1
7 =2
8 =4
9 =8
2 =16
3 =32
5 =64
4 =128
Ignore LED 1 (power on indicator), located adjacent
to X01; this LED will always be on when power is applied.
For example:
1) LED 6 and 8 = ON; all others off
LED 6 = 1
LED 8 = 4
total = 5
Software Version = ‘E05’
2) LED 7 and 8 = ON; all others off
LED 7 = 2
LED 8 = 4
total = 6
Software Version = ‘E06’
3) LED 6, 7, 9 and 2 = ON; all others off
LED 6 = 1
LED 7 = 2
LED 9 = 8
LED 2 = 16
total = 27
Software Version = ‘E27’
The LED indicators will continue to display the the
software version, regardless of operation, until switch 1
on SW3 is set to the ‘off’ possition.
DIP Switch 1 on SW3 must always be set to the ‘off’
position for normal operation.
DIP Switch 1 on SW3 has no function with earlier
software versions; if the LED indicators continue to
operate normally when SW3-1 is switched on, the
software is an earlier version; update the software.
Please refer to the table on the following page to assist in
decoding the software version number.

COMMISSIONING PROCEDURE
1) B
efore applying power to the X-IRI Gateway ensure:
a)
Version
The MODBUS address is set to the correct value
(switches 1-4 on SW1 and switches 1- 3 on SW2)
b)
The MODBUS port setup matches the MODBUS
master’s requirements. Switches 4 on SW2 and
switches 2-4 on SW3.
c)
The communication link wires from the Gateway
to the compressor controller and the MODBUS
master are connected, secure and the wire
polarities are correct (L1, L2).
2) Apply power to the X-IRI Gateway
3) Ensure communications with the compressor controller
is established – ensure indicator (9) is ON permanently.
4) Once the IR-BUS compressor controller communication
link is established the MODBUS master unit can start
operating. Any attempt from the MODBUS master to
communicate before the IR-BUS link is established will
simply result in the gateway not responding to the
MODBUS master.
5) Once the MODBUS master communicates with the
compressor controller through the gateway it should
keep on doing so at least once every 10 seconds to keep
indicator (6) from flashing.
6) In case the MODBUS master does not communicate at
least once every 10 seconds the communication link is
considered inactive: indicator (6) flashes and any earlier
commands for the compressor controller to operate in
“Host” mode are cancelled => the machine reverts back
to local start/stop and load/unload control mode.
