Setting Up the Quantum for
Communication
Data communication to and from the Quantum can be
through a modem, remote data communications terminal,
programmable controller, or leader computer via either
RS-422, RS-232, or RS-485 connections to the Quantum’s
Com-2 port. Reference the “Main Board Communications
Com-2” section for the correct jumpering of RS-422, RS-
232, or RS-485. Also reference the “Quantum Main
Board” section in this manual to identify wiring and
jumpering locations for Comm2.
Following is the RS-422, RS-485, and the RS-232 pin
descriptions for communications port 2 (also referred to as
Com-2 or Comm2):

Reference the “Quantum Main Board” section in this
manual for the location and positioning of the 10-pin RS-
232 connector.
Following is the pin connections showing how to wire a
standard 9-Pin RS-232 connector directly to the 10-Pin
RS-232 connector on the Quantum:
Note: The TX2 and RX2 are I/O communication activity
lamps on the Quantum Main Processor Board that can be
monitored to see if the Com-2 port is receiving (RX2) and
transmitting (TX2) data.
The use of communication protocols permit data
transmission between devices. Protocol determines how
contact is established and how the query and response
takes place. The information in a message command
requires an identity of the intended receiver, what the
receiver is to do, data needed to perform an action, and a
means of checking for errors.
When using Comm2 for communication, check what
communication protocol, if any, has been selected from
the Panel Setup – “Change Communications” display. For
example; “A-B Comm” should be selected when using
Allen-Bradley’s communication protocol. The baud rate of
Comm2 and the panel ID number are also changed from
this display and should coincide with the setup of the other
device.
Note: The data communication protocols are continuously
being expanded and improved. Therefore, you should
consult Frick Company for the exact details on your
particular unit(s) before developing system software to
interface with the panel.
Checklist for Setting Up Communication
1. Decide which Quantum protocol you can
communicate with and want to use.
2. Setup your device’s communication port for the
Quantum‘s protocol and select a baud rate.
3. Next, setup the Quantum for the desired
communication protocol. Select the protocol from the
Panel Setup – “Change Communications” display.
For example; “A-B Comm” should be selected when
using Allen-Bradley’s communication protocol.
4. Setup the baud rate of Comm2 to coincide with the
setup of the your device’s communication port.
5. Enter the Quantum’s ID. This will be used to identify
commands that are sent to it.
6. Wire to the first panel via RS-232, RS-422, or RS-485
connections to the Quantum’s Com-2 port.
•If you are communicating to more than one panel
then you will not be able to use RS-232. You can
however convert RS-232 to either RS-422 or RS-
485 with an adapter card. Reference the
“Converting an RS-232 Serial Port to RS-422 or
RS-485” section for information about an adapter
card.
•Reference the “Quantum Main Board” section in
this manual to identify wiring and jumpering
locations for Comm2.
•Reference the “Main Board Communications
Links” in this manual for the correct jumpering of
RS-232, RS-422, or RS-485.
7. Send a single command to read data from this
Quantum using it’s ID.
8. Check if you received a data response at your device.
9. Troubleshooting when you don’t receive a data
response:
•Check if Comm2 on the “Operating Status”
display is showing “ACTIVE” or “OFF”.
•“ACTIVE” is shown only when the Quantum
understands it is receiving a properly
composed message to itself.
•Check that the RX2 I/O communication activity
lamp on the Quantum Main Processor Board is
blinking as it receives the instruction from your
device.
•A steadily lit RX2 LED or one that isn’t
lighting are signs of improper wiring.

• If the RX2 LED is properly blinking, then check if
the TX2 LED is blinking in response.
• If the TX2 is not blinking, then check the
communication protocol setup at the panel,
the panel’s ID and the Comm2 baud rate
setting.
• If the TX2 is blinking, then check that the
Comm2 communication jumpers are correct.
• If you are sure that the wiring and Quantum
setup is correct, then select the [Show
Comms] key from the “Service Screen”
display to see what is being received and
transmitted from Comm2.
Note: A useful tool for troubleshooting is Windows
“HyperTerminal”. Using “HyperTerminal” can help you
determine if you are wired correctly. Reference the
“HyperTerminal Setup” (page 35) section in this
manual.
10. If you properly receive data and you need to
communicate to more than one panel, then setup and
wire to another panel. Reference the wiring diagram
drawings in the back of this manual. Send a single
command to read data from this Quantum using it’s ID
and troubleshoot as above, if necessary.
11. To prevent noise feedback which is possible when
communicating over a long distance, only the last
panel should have the transmit and receive pull-down
for long communications lines jumpered.
Frick Protocols
All commands for Frick protocols must be in ASCII to be
recognized. The data should be setup as an 8 bit Word
with either no Parity or even Parity, and a Stop Bit. The
commands can be in upper or lower case letters. An
ACUair panel with an ID code of [00] is considered
disabled. ID codes from [01] through [99] are valid and
recognized by the microprocessor.
Quantum’s Protocol Specifications
Quantum’s (“$”) protocol commands have been added
specifically for the Quantum. Unless otherwise shown, 9
characters are returned from the Quantum for a data
value. The data value includes two decimal fields and the
first character position is either; “-“ if the value is negative,
or it is “+” if the value is positive. For example, if the
data’s value is 25.5; then the value +00002550 is sent. All
temperatures are in degrees C and all pressures are in
PSIA. A mode such as “Current ACUair Mode” is returned
as an integer value that represents the mode it is in. For
example, a +00000000 is sent if it is in “Process Mode” or
a +00000100 is sent if it is in “Cleanup Mode”. The value
zero +00000000 is used to represent an “OFF” status and
a “DISABLED” option. The value one +00000100, which
is received as a 1, is used to represent an “ON” status and
an “ENABLED” option. Setpoints are only changed if the
value sent is within the acceptable range. The checksum
is the 2 byte hexadecimal sum of each character within the
command or returned answer, excluding the command
type identifier, ”$”. If the command’s checksum is
replaced with “??”, the Quantum returns a response
without using checksum error checking on the received
command. If the Quantum detects a checksum error, a
“N” (Not Acknowledged), the ACUair ID code, “02”,
Carriage return, and Linefeed are returned.
With the ACUair control system, all Unit-specific
setpoints are stored at the GCU board and are only loaded
to the Quantum panel as needed. As a result, delays will
be encountered when reading or writing these setpoints as
the values are sent between the Quantum and GCU
board. To properly read or change setpoints it is
necessary to follow certain procedures. First, the
command should be sent to change the Panel Control
Status to Remote. The Quantum screen will immediately
move to the Unit Overview screen and the Panel Control
Status will be set to Remote. At this point, a command
may be sent to read or write setpoint values. Expect to
wait a second or two while the required values are
downloaded from the GCU board. When reading values
from the GCU that may change periodically, such as the
Alarm List, send the Refresh Setpoints command before
reading the values to verify that current settings are being
read. Also be aware, if a person presses the "Login to
Unit" button on the Quantum, the Panel Control Status will
be set to Manual. This will prevent a remote system from
reading or writing setpoints stored at the GCU board until
the Panel Control Status is reset to Remote.

ACUair COMMUNICATIONS SETUP Page 9
Allen-Bradley Communication
To provide for the reading and writing of data to Quantum
panels using Allen-Bradley communication, the Quantum
has an Allen-Bradley DF1 communication driver that
recognizes both half-duplex and full duplex SLC 500
protected typed logical read and write commands. This is
a Leader / Follower multi-drop communication method.
The Quantum talks Allen-Bradley SLC protocol and is
setup to be an Allen-Bradley SLC500 follower station. The
customer’s PLC or DCS must be setup to initiate the
reading and writing of data to a Quantum. The Quantum’s
ID number is used as it’s station address and the target
node. With the AB PLC, the MSG (Message) instruction
is used to send read and write requests. A DCS
(Distributed Control System) will use a SLC 500 DF1
protocol driver to send protected typed logical read and
protected typed logical write requests to a Quantum.
Fifty (50) data elements can be read with one read.
Setpoints are changed by sending a write command to
one element. Be careful not to continuously request
a setpoint change. Keeping the Quantum busy
writing to an individual GCU board will interfere with
the Quantum's polling of all the GCU boards. Control
commands are also sent with a write command. For
more detail and a list of the data, reference the
“Quantum Data Table” section. For details about the
actual protocol, reference the AB publication 1770-6.5.16
“DF1 Protocol and Command Set Reference Manual”.
The Quantum can be connected to the Data Highway (DH)
by wiring the Quantum’s serial port (Com-2) to a serial
device on the DH such as an internal port of a PLC that
supports the Data Highway protocol like the SLC 5/04.
Quantum's can be on a multi-drop link (wired to other
Quantum's). If RS-422 or RS-485 is used as in a multi-
drop link, an adapter card can be used to convert an
RS-232 to an RS-422 or RS-485 serial port.
Because overrun can occur and result in the Quantum
periodically missing characters, the baud rate and
commands should be setup to produce the most desired
throughput. The leader station should have the Stop Bit
set to 1, Parity set to none, Duplicate Detect disabled, and
Error Detect set for BCC.
When communication is between either your programming
software and a Quantum or an Allen-Bradley PLC and a
Quantum on a multi-drop link, the devices depend on a
DF1 Leader to give each of them polling permission to
transmit in a timely manner. As the number of Quantum
followers increase on the link, the time between when
the Quantum is polled also increases. This increase, in
time, may become larger if you are using low baud
rates. As these time periods grow, the timeouts,
such as the message timeout, poll timeout, and
reply timeout may need to be changed to avoid loss of
communication.
ACK Timeout - The amount of time in 20 milliseconds
increments that you want the processor to wait for an
acknowledgment to the message it has sent before the
processor retries the message or the message errors out.
Reply Message Wait Time - Define the amount of time in
20 millisecond increments that the leader station will wait
after receiving an ACK (to a leader-initiate message)
before polling the remote station for a reply. Choose a
time that is, at minimum, equal to the longest time that a
remote station needs to format a reply packet. Some
remote stations can format reply packets faster than
others.
Message Timeout - Defines the amount of time in
seconds that the message will wait for a reply. If this time
elapses without a reply, the error bit is set, indicating that

that there is no timer and the message will wait indefinitely

PLC-5/30 - Suggested Setup
Channel 0 - 25-pin D-shell serial port; supports standard
EIA RS-232C and RS-423 and is RS-422A compatible.
NOTE: Channel 0 is optically-coupled (provides high
electrical noise immunity) and can be used with most
RS-422A equipment as long as:
•termination resistors are not used
•the distance and transmission rate are reduced to
comply with RS-423 requirements
The PLC-5’s switch 2 is used to select RS-232C, RS-
422A, or RS-423. Channel 0 can be wired for RS-422.
Following is the pin connections showing how to wire the
PLC-5 channel 0 connector to the Quantum for RS-422
communication:
PLC-5 CH0 Quantum Com-2
Pin 2 (TXD.OUT+) Pin 1 (-RX)
Pin 3 (RXD.IN+) Pin 3 (-TX)
Pin 14 (TXD.OUT-) Pin 2 (+RX)
Pin 16 (RXD.IN-) Pin 4 (+TX)
Channel 0 Setup:
Port Maximum Cable
length
RS-232C 15 m (50 ft)
RS-422A 61 m (200 ft)
RS-423 61 m (200 ft)
Important guidelines:
•When channel 0 is configured for RS-422A
compatibility, do not use terminating resistors
anywhere on the link.
•When channel 0 is configured for RS-422A
(compatible) and RS-423, do not go beyond 61 m
(200 ft). This distance restriction is independent from
the transmission rate.

Modbus Communication
The Quantum provides the capability to interface with
other devices that support serial data communications
using the Modbus ASCII protocol. This is a Leader /
Follower multi-drop communication method. The
Quantum is setup to be a Modbus ASCII Follower.
The customer’s PLC or DCS must be setup as a
Modbus ASCII Leader. The Leader initiates the
reading and writing of data to a Quantum. The
Quantum’s ID number is used as the Modbus
Follower address. The Leader uses Function Code 3
(Read Holding Registers) to read data from the
Quantum and Function Code 6 (Load Register) to change
a setpoint or to send a command such as the “Clear
Alarms” command. Fifty (50) data elements can be read
with one read request. The address references are
numbered relative to the Frick addresses in the Quantum
Data Table. For example, to reference Frick data address
128 enter the decimal value 128 for the Modbus
Follower Address. The Quantum only excepts one
value with a Load Register request. Be careful not to
continuously request a setpoint change. Keeping the
Quantum busy writing to an individual GCU board will
interfere with the Quantum's polling of all GCU boards.
For more detail and a list of the data, reference the
“Quantum Data Table” section. For details about the
actual protocol, reference the Gould publication PO-
MBUS-300 Gould Modbus Protocol Reference
Manual”.

7 Bits per Character

Quantum Data Table
Allen-Bradley and Modbus Data Access
Data passed to and from the Quantum are integer values
with one decimal field assumed unless shown otherwise or
the command is sent to select two decimal fields. For
example, if the data’s value is 25.5 then the value 255 is
sent. All temperatures are in degrees C and all pressures
are in PSIA, unless the command is sent to select the
units of the panel. A mode such as “Current ACUair Mode”
is sent as an integer value that represents the mode it is
in. For example, a 0 is sent if it is in “Process Mode”, or a
10 is sent if it is in “Cleanup Mode”. The value zero (0) is
used to represent an “OFF” status and a “DISABLED”
option. The value one (1), which is received as a 10, is
used to represent an “ON” status and an “ENABLED”
option. Only data values that are designated as
setpoints are modifiable. “Read Only” is used to help
identify what data is not modifiable. The setpoint range is
checked to see if it is an allowed setting. If it is not
allowed, the setting is not changed. Reference the “Frick
ACUair Quantum Control Panel Setpoints Data Sheets” for
the setpoint's default settings and ranges. Reference the
“Quantum Data Table” for the address listing and
description of data.
A command has been provided that selects whether data
to and from the Quantum will be integer values with either
one or two decimal fields assumed. Another command has
been provided that selects whether data to and from the
Quantum will be returned in the units that are the default
(pressure in PSIA and temperature in Degree C) or in the
units that are selected to display at the panel.
With the ACUair control system, all unit-specific setpoints
are stored at the GCU board and are only loaded to the
Quantum panel as needed. As a result, delays will be
encountered when reading or writing these setpoints as
the values are transferred between the Quantum and GCU
board. Setpoints whose Frick addresses are in the
following ranges should be considered unit-specific: 200-
569, 700-1069, 1200-1569 and 1700-2069.
To properly read or change the unit-specific setpoints
stored at the GCU, it is necessary to follow certain
procedures. First, a command should be sent to change
the Panel Control Status to “Remote”. The Quantum
screen will immediately move to the Unit Overview display
and the Panel Control Status will be set to Remote. At this
point, a command may be sent to read or write setpoint
values.
When using the Modbus protocol, expect to wait a up to
several seconds while the required values are downloaded
from the GCU board. With the Allen-Bradley protocol, the
first time a value or set of values are requested, no data is
returned, but the data is downloaded from the GCU board.
The same data request should be sent several seconds
later, and the downloaded data will now be returned.
When setpoints are changed, the Quantum will reply to the
Allen-Bradley or Modbus command and then write the
change to the GCU board. After sending a write
command, wait approximately a second before sending
the next command. These operational methods, when
used properly, allow a person to make a large number of
setpoint changes without stalling communications.
When reading values from the GCU board that may
change periodically, such as the Alarm List, send the
Refresh Setpoints command before reading the values to
verify that current settings are being read. Also be aware,
if a person presses the "Login to Unit" button at the
Quantum, the Panel Control Status setting will be set to
Manual. This will prevent a remote system from reading or
writing the setpoints until the Panel Control Status is reset
to Remote.
