SETTING UP THE QUANTUM

FOR COMMUNICATION

Data communication to and from the Quantum can be through

a modem, remote data communications terminal, program-

mable 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

Jump-ers” section for the correct jumpering of RS-422,

RS-232, or RS-485. Also reference the drawing of the

“Quantum Main Processor Board” (in publication S90-010

M) to identify wir-ing and jumpering locations for Comm2.

Following are the RS-422, RS-485, and RS-232 pin descrip-

tions for communications port 2 (also referred to as Com-2

or Comm2):

10 Not Used

Reference the drawing of the main processor board for the

location and positioning of the 10-Pin RS-232 connector.

Following is the pin connections showing how to wire a stan-

dard 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 transmis-

sion 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 com-

munication 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 continu-

ously being expanded and improved. Therefore, you

should consult Frick Company for the exact details on

your particular unit(s) before developing system soft-

ware 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 communica-

tion 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 adaptor card. Reference the “Convert-

ing an RS-232 Serial Port to RS-422 or RS-485”

section for information about an adapter card.

•Reference the drawing of the “Quantum Main Pro-

cessor Board”(in publication S90-010 M) to iden-

tify wiring and jumpering locations for Comm2.

•Reference the “Main Board Communications -

Com-2 Jumpers” section in this manual for the cor-

rect jumpering of RS-232, RS-422, or RS-485.

7. Send a single command to read data from this Quan-

tum using it’s ID.

8. Check if you received a data response at your device.

9. Troubleshooting when you don’t receive a data re-

sponse:

•Check if Comm2 on the “Operating Status” display

is showing “ACTIVE” or “OFF”.

FRICK QUANTUM CONTROL PANEL

COMMUNICATIONS SETUP

S90-010 CS

Page 4

•“ACTIVE” is shown only when the Quantum

understands it is receiving a properly com-

posed 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 steady 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 com-

munication 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

figure out if you are wired OK. Reference the

“HyperTerminal Setup” section in this manual.

10. If you properly receive data and you need to communi-

cate 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 trouble-

shoot as above, if necessary.

11. To prevent noise feedback which is possible when com-

municating over a long distance, only the last panel

should be jumpered for long distance communication.

J68, J89, and J90 on the main board should be jumpered

for RS-422/485 communication lines. J91 and J92

should be jumpered for RS-422 communication lines.

FRICK PROTOCOLS

All commands for Frick protocols must be in ASCII to be recog-

nized. 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. A compressor with an ID code of

[00] is considered disabled. ID codes from [01] through [99]

are valid and recognized by the microprocessor.

FRICK’S “#” PROTOCOL SPECIFICATIONS

Frick’s “#” protocol consists of commands that are available

for most other existing models of Frick control panels. It is

better to use Frick’s Quantum (“$”) protocol when only com-

municating to Quantum panels.

When there is more than one panel, a Quantum can be wired

from it’s Com-2 to another Quantum’s Com-2 or a Quantum

can be wired from it’s Com-2 to Port 1 of a RWB, RDB, RXB

or RXF panel.

The following is a complete list of available “#” commands:

COMMAND CODE and DESCRIPTION

I = Returns compressor status information.

R = Compressor start command.

S = Compressor stop command.

V = Slide valve/slide stop command.

P = Return Pressures information.

A = Return full load amps information.

T = Return Temperatures information.

Q = Query setpoints data.

C = Enter Change setpoints mode.

MC= Change compressor mode.

MV= Change slide valve mode.

KF = Clear Failures.

KR = Clear remaining recycle delay time.

X = Return digital I/O status.

F = Return Failures.

All data are returned as integer values. If decimal positions

are assumed, then divide the data by the proper multiple of

10 to get the actual value.

“Temperature” data, except for suction temperature, is re-

turned in the current temperature units as 3 characters with

no decimal position (i.e. 032 would represent 32 degree

Fahrenheit if the Quantum’s temperature units are in Fahr-

enheit or it would represent 32 degree Celsius if the

Quantum’s temperature units are in Celsius). Suction tem-

perature is returned as 4 characters with a “+” or “-” as the

leading character (i.e. -010 would represent -10 degrees).

“Pressure” data is usually returned in the current pressure

units. However, the Filter differential reading is always re-

turned in PSIA. When in PSIG or in PSIA, the pressure data

is returned as 3 characters with no decimal position. How-

ever; in order to show the full transducer range, the #IDPS

command returns 4 characters with one decimal position

assumed. The #IDI and #IDPA commands return 3 charac-

ters that assume one decimal position; therefore, 99.9 is the

highest value that can be returned. When in PSIG, suction

pressure is returned in PSIA. When in Bar and BarA, the

pressure data is returned as 4 characters with two decimal

positions assumed. When in KpaA, the pressure data is

returned as 4 characters with no decimal position.

The following is a detailed description of each command:

QUANTUM’S PROTOCOL SPECIFICATIONS

Quantum’s (“$”) protocol commands have been added spe-

cifically for the Quantum. Unless otherwise shown, 9 charac-

ters are returned from the Quantum for a data value. The data

value includes two decimal fields and the first character posi-

tion 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 degree C

and all pressures are in PSIA. A mode such as slide valve

mode is returned as an integer value that represents the mode

it is in. For example, a +00000000 is sent if it is in manual, or

a +00000100 is sent if it is in automatic, or a +00000200 is

sent if it is in remote. 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 repre-

sent an “ON” status and an “ENABLED” option. Setpoints are

only changed if the value sent is within the acceptable range.

Reference the “Frick Quantum Control Panel Setpoints Data

Sheets” publication S90-010 SD for the setpoints default set-

tings and ranges. The checksum is the 2 byte hexadecimal

sum of the each character within the command or returned

answer excluding the command type identifier, ”$”. If the

command’s checksum is replaced with “??”,the Quantum re-

turns a response without using checksum error checking on

the received command. If the Quantum detects a checksum

error, a “N” (Not Acknowledged), the Compressor ID code,

“02”, Carriage return, and Linefeed are returned.

ALLEN-BRADLEY COMMUNICATION

To provide for the reading and writing of data to Quantum

panels using Allen-Bradley communication, the Quantum has

a 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 a

Allen-Bradley SLC 500 follower station. The customer’s

PLC or DCS must be setup to initiate the reading and

writing of data to a Quan-tum. The Quantum’s ID number

is used as it’s station ad-dress and the target node. With

the AB PLC, the MSG (Mes-sage) 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 pro-tected typed logical

write requests to a Quantum. Fifty (50) data elements can

be read with one read. The most desired data (information

on the “Operating Status” display) exists in a fifty (50)

element data area. Setpoints are changed by sending a

write command to one element. Changing a set-point

causes the Quantum to save the new setpoint to

EPROM memory (nonvolatile memory). Be careful not to

continuously request a setpoint change. Keeping the Quan-

tum busy writing to EPROM memory will interfere with the

Quantum communicating to it’s I/O Boards. A communica-

tion failure to an I/O board will cause the compressor to

shutdown. Control commands such as starting the com-

pressor 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 de-

vice on the DH such as an internal port of a PLC that sup-

ports the Data Highway protocol like the SLC 5/04.

Quantums can be on a multidrop link (wired to other

Quantums). If RS-422 or RS-485 is used as in a multidrop

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 peri-

odically missing characters, the baud rate and commands

should be set up to produce the more 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 multidrop 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

in-crease 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 time-outs such as the message time-out,

poll time-out and reply time-out may need to be changed

to avoid loss of communication.

ACK Time-out - The amount of time in 20 milliseconds in-

crements that you want the processor to wait for an acknowl-

edgment 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) be-

fore 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 sta-

tions can format reply packets faster than others.

Message Time-out - Defines the amount of time in sec-

onds that the message will wait for a reply. If this time elapses

without a reply, the error bit is set, indicating that the instruc-

tion timed out. A time-out of 0 seconds means that there is

no timer and the message will wait indefinitely for a reply.

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 com-

munication:

PLC-5 CH0 Quantum Com2

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 dis-

tance 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

multidrop 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 send a request to read data from the Quantum

and Function Code 6 (Load Register) to request to change a

setpoint or to send a command such as starting the

compressor. Fifty (50) data elements can be read with one

read request. The most desired data (information on the

“Operating Status” display) exists in a fifty (50) element

data area. The address references are numbered relative to

the Frick addresses in the Quantum Data Table. For example,

to reference Frick’s data address 128 enter the decimal value

128 for the Modbus Follower Address. The Quantum only

ac-cepts one value with a Load Register request.

Changing a setpoint causes the Quantum to save the

new setpoint to EPROM memory (nonvolatile memory). Be

careful not to con-tinuously request a setpoint change.

Keeping the Quantum busy writing to EPROM memory will

interfere with the Quan-tum communicating to it’s I/O Boards.

A communication failure to an I/O board will cause the

compressor to shutdown. 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 odbus Protocol Reference Manual”.

PORT CONFIGURATION OF THE LEADER:

7 Bits per Character

No Parity

1 Stop Bit

No Handshake

HYPERTERMINAL SETUP

A modem or direct connection from a Comm port of a computer

running Windows 9x/NT can be used to connect to Com-2 of the

Quantum. From the HyperTerminal setup, select the type of con-

nection (i.e. Standard Modem, Direct to Com-1, etc.)

Setup the port settings to coincide with the Quantum’s Com-2

port settings:

Bits per second: (User changeable at Quantum)

Data Bits: 8

Parity: None

Stop bits: 1

Flow Control: None

Set up the function, arrow, and ctrl keys to act as: Terminal

Keys. And select ANSII emulation. If using the Frick “$” pro-

tocol, the check box to send line ends with line feeds should

not be checked. Check that the ID code used in a command

string coincides with the panel’s ID.

CONVERTING AN RS-232 SERIAL PORT TO

RS-422 OR RS-485

An adapter card can be used to convert an RS-232 serial

port to an RS-422 or RS-485 serial port. With RS-422 or

RS-485, the cable length can be extended to 5000 feet and

several Quantums can be multidropped. We have used both

an Opto 22 AC7A/B and an Opto 22 AC422 adapter card.

They can be wired to use either RS-422 or RS-485.

Opto 22 AC7A/B

The AC7A/B card is installed external to a computer and

requires wiring to a power supply. For example, it can be

used in a standalone panel along with a Allen Bradley SLC

5/04 or maybe along with an external modem. Keeping the

jumpers installed the same way they are received from the

factory, it is easy to wire for either RS-422 or RS-485.

Following is the pin connections showing how to wire a DB9

connector on this adapter card to the Quantum for RS-422

communication:

Following is the pin connections showing how to wire for

RS-485 to the terminal connections on this adapter card

pin RS-232 connector on this adapter card to a 9-Pin con-

nector of the SLC 5/04:

QUANTUM DATA TABLE

ALLEN-BRADLEY AND MODBUS DATA ACCESS

Data to and from the Quantum are integer values with one

decimal field assumed unless shown otherwise or the com-

mand is sent to select two decimal fields. For example, if the

data’s value is 25.5, then the value 255 is sent. All tempera-

tures are in degree C and all pressures are in PSIA unless

the command is sent to select the units of the panel. A mode

such as slide valve mode is sent as an integer value that

represents the mode it is in. For example, a zero 0 is sent if

it is in manual, or a 10 is sent if it is in automatic, or a 20 is

sent if it is in remote. 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

Quantum Control Panel Setpoints Data Sheets” publication

S90-010 SD for the setpoints default settings and ranges.

Reference the “Quantum Data Table” for the address listing

and description of data. NOTE: The Frick address is used

to reference the Modbus 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 Quan-

tum will be returned in the units that are the default (pres-

sure in PSIA and temperature in Degree C) or in the units

that are selected to display at the panel.
