WARNING!


Quantum™ IdentificationFrick® Controls has over the years, strived to remain onthe cutting edge of microprocessor technology anddevelopment. Because of the ever-increasing speed,memory, features, and power of microprocessors, Frick®

Controls will continue to introduce the latest advancementin microprocessor control technology.

Our microprocessor family has shared the nameQuantum™, over the past five years. There are currentlyfour controllers within this family. The first two of thesecontrollers (known as Quantum™ 1 and Quantum™ 2) areno longer in production, and as such, will not be furthermentioned in this manual. The two current members inproduction of the Quantum™ family are the Quantum™ 3,and the Quantum™ 4. It is critical to the end user to beable to identify the differences between these controllers.Refer to the section in this manual entitled Quantum™ 3Main Board History and Identification and Quantum™ 4Main Board History and Identification for additionalinformation as to how to identify the particular Quantum™controller that you have.

Throughout this manual, the two different controllers willbe talked about for the most part as one (as they dofunction the same). Where there is a difference betweenthese boards, as in jumpers or wiring, the different modelswill be identified by name. This is why it is important foryou to be aware of which Quantum™ board you have.

Quantum™ 3

Quantum™ 4

Setting Up the Quantum™ forCommunication

Data communication to and from the Quantum™ can bethrough a modem, remote data communications terminal,programmable controller, or master computer via eitherRS-422, RS-232, or RS-485 connections to theQuantum™ Com-2 port. Reference the “Main BoardCommunications” section for the correct jumpering of RS-422, RS-232, or RS-485. Also, reference the drawing ofthe “Quantum™ Main Board” section to identify wiringconfigurations for Com-2.

RS-232 Communications

Following is the pin connections showing how to wire astandard 9-Pin RS-232 connector directly to the 10-PinRS-232 connector on the Quantum™ 3, and the 3-pinconnector on the Quantum™ 4:

Quantum™ 3

Reference the drawing of the main processor board for thelocation and positioning of the 10-Pin RS-232 connector.Following is the pin positions of the 10-Pin connector:

Note: The TX2 and RX2 are I/O communication activitylamps on the Quantum™ Main Processor Board that canbe monitored to see if the Com-2 port is receiving (RX2)and transmitting (TX2) data.

Quantum™ 4

Reference the drawing of the main processor board for thelocation and positioning of the 3-Pin RS-232 connector.Following is the pin positions of the 3-Pin connector:

Converting an RS-232 Serial Port to RS-422or RS-485

In order to communicate to the Quantum™ controller viaRS-422 (or RS-485), you will need to convert the RS-232signal from the source.

One converter that has proven to be effective is the Opto-22 AC7A/B card. This card will allow the conversion from astandard RS-232 signal to either RS-422 or RS-485. TheAC7A card is powered from a 115 VAC source, while theAC7B card is powered from a 220 VAC source. They canbe used in a standalone panel along with an Allen BradleySLC 5/04 or along with an external modem. Keeping thejumpers installed the same way they are received from thefactory, it is easy to wire for either RS-422 or RS-485.

NOTE: Refer to the manual that comes with the AC7A/Bcard for specific jumper information (as the configurationshown is only a suggestion that has worked in mostapplications).

Once jumpers on the converter card have been verified,you will need to verify the jumper settings of theQuantum™ controller. Refer to the following diagrams forthe Quantum™ 3 and Quantum™ 4:

Quantum™ 3

Quantum™ 4

NOTE: Some of these jumpers settings may need to bemodified to ensure optimum communicationsperformance. Typically, the termination jumper should beinstalled in the last Quantum™ in the communicationsdaisy chain only (Link 7 for the Quantum™ 3, Link 1 forthe Quantum™ 4).

Protocol DescriptionThe use of communication protocols, permits datatransmission between devices. Protocol determines howcontact is established and how the query (question) andresponse (answer) takes place. The information in amessage command requires an identity of the intendedreceiver (ID #), what the receiver is to do (read or write toa setpoint, etc.), data needed to perform an action (thevalue of a setpoint to be changed), and a means ofchecking for errors (checksum).

When using Com-2 for communication, check whatcommunication protocol, if any has been selected, fromthe Panel Setup – “Change Communications” screen. Forexample, “A-B Comm” should be selected when usingAllen-Bradley’s communication protocol. The baud rate ofCom-2 and the panel ID number are also changed fromthis screen, and should coincide with the setup of theother device.

Note: The data communication protocols are continuouslybeing expanded and improved. Therefore, you shouldconsult Frick Controls for the exact details on yourparticular unit(s) before developing system software tointerface with the panel.

Quantum™ Protocols

The Quantum™ controller has the capability ofcommunicating to the outside world through three softwareprotocols:

• Frick

• Allen-Bradley DF-1 serial• Modbus ASCII serial

Checklist for Setting Up Communication1. Decide which Quantum™ protocol you can

communicate with and want to use.

2. Setup your device’s communication port for theQuantum™ protocol and select a baud rate.

3. Next, setup the Quantum™ for the desiredcommunication protocol. Select the protocol fromthe Panel Setup – “Change Communications”screen. For example, “A-B Comm” should beselected when using Allen-Bradley’scommunication protocol.

4. Setup the baud rate of Com-2 to coincide with thesetup of the your device’s communication port.

5. Enter the Quantum™ ID. This will be used toidentify commands that are sent to it.

6. Wire to the first panel via RS-232, RS-422, orRS-485 connections to the Quantum™ Com-2port.

• If you are communicating to more than onepanel, then you will not be able to use RS-232. You can however, convert RS-232 toeither RS-422 or RS-485 with an adaptercard. Reference the “Converting an RS-232Serial Port to RS-422 or RS-485” section forinformation about an adapter card.

• Reference the drawing of the “Quantum™Main Board” in this manual to identify wiringand jumpering locations for Com-2.

• Reference the “Main Board CommunicationsCom-2” section in this manual for the correctjumpering of RS-232, RS-422, or RS-485.

7. Send a single command to read data from thisQuantum™ using its ID.

8. Check if you received a data response at yourdevice.

9. Troubleshooting when you don’t receive a dataresponse:

• Check that the RX2 I/O communicationactivity lamp on the Quantum™ MainProcessor Board is blinking as it receives theinstruction from your device.

• A steady lit RX2 LED or one that isn’tlighting, are signs of improper wiring.

• If the RX2 LED is properly blinking, thencheck if the TX2 LED is blinking in response.

• If the TX2 is not blinking then check thecommunication protocol setup at the panel,the panel’s ID and the Com-2 baud ratesetting.

• If the TX2 is blinking, then check that theCom-2 communication jumpers are correct.

• If you are sure that the wiring andQuantum™ setup is correct, then select the[Show Comms] key from the “ServiceScreen” to see what is being received andtransmitted from Com-2.

Note: A useful tool for troubleshooting isWindows “Hyperterminal”. Using Hyperterminalcan help you determine if you are wired OK.Reference the “Hyperterminal Setup” section inthis manual.

10. If you properly receive data and you need tocommunicate to more than one panel, then setupand wire to another panel. Reference the wiringdiagram drawings in the back of this manual.Send a single command to read data from thisQuantum™ using it’s ID and troubleshoot asabove, if necessary. To prevent noise feedbackwhich is possible when communicating over along distance, only the last panel should have thetermination for long communications linesjumpered.


Frick® ProtocolsAll commands for Frick® protocols must be in ASCII to berecognized. The data should be setup as an 8 bit Wordwith either no Parity or even Parity, and a Stop Bit. Thecommands can be in upper or lower case letters. AnACUair® panel with an ID code of [00] is considereddisabled. ID codes from [01] through [99] are valid andrecognized by the microprocessor.

Quantum’s Protocol Specifications

Quantum’s (“$”) protocol commands have been addedspecifically for the Quantum. Unless otherwise shown, 9characters are returned from the Quantum for a datavalue. The data value includes two decimal fields and thefirst character position is either; “-“ if the value is negative,or it is “+” if the value is positive. For example, if thedata’s value is 25.5; then the value +00002550 is sent. Alltemperatures are in degrees C and all pressures are inPSIA. A mode such as “Current ACUair Mode” is returnedas an integer value that represents the mode it is in. Forexample, a +00000000 is sent if it is in “Process Mode” ora +00000100 is sent if it is in “Cleanup Mode”. The valuezero +00000000 is used to represent an “OFF” status anda “DISABLED” option. The value one +00000100, whichis received as a 1, is used to represent an “ON” status andan “ENABLED” option. Setpoints are only changed if thevalue sent is within the acceptable range. The checksumis the 2 byte hexadecimal sum of each character within thecommand or returned answer, excluding the commandtype identifier, ”$”. If the command’s checksum isreplaced with “??”, the Quantum returns a responsewithout using checksum error checking on the receivedcommand. 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 setpointsare stored at the GCU board and are only loaded to theQuantum panel as needed. As a result, delays will beencountered when reading or writing these setpoints asthe values are sent between the Quantum and GCUboard. To properly read or change setpoints it isnecessary to follow certain procedures. First, thecommand should be sent to change the Panel ControlStatus to Remote. The Quantum screen will immediatelymove to the Unit Overview screen and the Panel ControlStatus will be set to Remote. At this point, a commandmay be sent to read or write setpoint values. Expect towait a second or two while the required values aredownloaded from the GCU board. When reading valuesfrom the GCU that may change periodically, such as theAlarm List, send the Refresh Setpoints command beforereading the values to verify that current settings are beingread. Also be aware, if a person presses the "Login toUnit" button on the Quantum, the Panel Control Status willbe set to Manual. This will prevent a remote system fromreading or writing setpoints stored at the GCU board untilthe Panel Control Status is reset to Remote.

Allen-Bradley CommunicationTo provide for the reading and writing of data toQuantum™ panels using Allen-Bradley communication,the Quantum has an Allen-Bradley DF1 communicationdriver that recognizes both half-duplex and full duplex SLC500 protected typed logical read and write commands.This is a Master / Slave multi-drop communicationmethod. The Quantum™ talks Allen-Bradley SLC protocoland is programmed to resemble an Allen-Bradley SLC500slave station. The customer’s PLC or DCS must be setupto initiate the reading and writing of data to a Quantum™.The Quantum™ does not initiate any communications.The Quantum™ panels ID number is used as it’s stationaddress and the target node. With the AB PLC, the MSG(Message) instruction is used to send read and writerequests. A DCS (Distributed Control System) will use aSLC 500 DF1 protocol driver to send protected typedlogical read with 3 address fields and protected typedlogical write requests with 3 address fields to aQuantum™. Fifty (50) data elements can be read with oneread. Setpoints are changed by sending a write commandto one element. Be careful not to continuously request asetpoint change. Keeping the Quantum™ busy writing toan individual GCU board will interfere with the Quantum'spolling of all the GCU boards. Control commands are alsosent with a write command. For more detail and a list ofthe data, reference the “Quantum™ Data Table” section.For details about the actual protocol, reference the ABpublication 1770-6.5.16 “DF1 Protocol and Command SetReference Manual”.

The Quantum can be connected to the Data Highway (DH)by wiring the Quantum’s serial port (Com-2) to a serialdevice on the DH such as an internal port of a PLC thatsupports the Data Highway protocol like the SLC 5/04.Quantum's can be on a multi-drop link (wired to otherQuantum'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, the baud rate and commandsshould be setup to produce the most desired throughput.The master station should have the Stop Bit set to 1,Parity set to none, Duplicate Detect disabled, and ErrorDetect set for BCC or CRC.When communication is between either your programmingsoftware and a Quantum™ or an Allen-Bradley PLC and aQuantum™ on a multi-drop link, the devices depend on aDF1 Master to give each of them polling permission totransmit in a timely manner. As the number of Quantum™slaves increase on the link, the time between when theQuantum™ is polled also increases. This increase in timemay become larger if you are using low baud rates. Asthese time periods grow, the timeouts, such as themessage timeout, poll timeout, and reply timeout mayneed to be changed to avoid loss of communication.

ACK Timeout - The amount of time in 20 millisecondsincrements that you want the processor to wait for anacknowledgment to the message it has sent before theprocessor retries the message or the message errors out.

Reply Message Wait Time - Define the amount of time in20 millisecond increments that the master station will waitafter receiving an ACK (to a master-initiate message)before polling the remote station for a reply. Choose atime that is, at minimum, equal to the longest time that aremote station needs to format a reply packet. Some

remote stations can format reply packets faster thanothers.

Message Timeout - Defines the amount of time inseconds that the message will wait for a reply. If this timeelapses without a reply, the error bit is set, indicating thatthe instruction timed out. A timeout of 0 seconds meansthat there is no timer and the message will wait indefinitelyfor a reply. Valid range 0-255 seconds.

Note: Make sure the Allen-Bradley PLC and theprogramming software is the most recent softwarerevision. Some revisions have been made that affectdoing the SLC Typed Logical Read/Write MessageCommand.

NOTE: Channel 0 is optically-coupled (provides highelectrical noise immunity) and can be used with mostRS-422A equipment as long as:

• termination resistors are not used

• the distance and transmission rate are reduced tocomply 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.

MODBUS ProtocolSince Modbus protocol is a messaging structure, it isindependent of the underlying physical layer. It istraditionally implemented using RS-232, RS-422, or RS-485 communications hardware.

The Quantum™ controller is setup to communicate onstandard Modbus networks using ASCII (AmericanStandard Code for Information Interchange).

NOTE: With the Quantum™ Controller, ONLY ModbusASCII (7 data bits) is recognized, and all references toModbus protocol in this document will be as they relate toASCII. The mode and serial parameters must be the samefor all devices on a Modbus network, therefore, ensurethat your network is utilizing the Modbus ASCII protocolbefore attempting to try to communicate to the Quantum™portion of the network. Additionally, typical Modbusprotocols allow for network broadcasting, whereby a singlemessage can be sent to all devices simultaneously. ThisBroadcasting is NOT allowed or supported by theQuantum™ Controller.

The Quantum™ provides the capability to interface withother devices that support serial data communicationsusing the Modbus ASCII protocol. This is a Master / Slavemulti-drop communication method whereby theQuantum™ is setup to be a Modbus ASCII Slave. Thecustomer’s PLC (Programmable Logic Controller) or DCS(Data Communications System, such as a desktop orlaptop computer) must be setup as a Modbus ASCIIMaster. The Master initiates the reading and writing ofdata (queries) to a Quantum™. The Quantum™ does notgenerate its own data, it will only reply from a request bythe Master.

The Quantum™ ID number is used as the Modbus Slaveaddress. The Master uses Function Code 3 (Read HoldingRegisters) to send a request to read data from theQuantum™. The Master uses Function Code 6 (LoadRegister) to request to change a setpoint or to send acommand such as starting the compressor. Up to fifty (50)data elements can be read with one read request.

Address references are numbered relative to the Frick

addresses in the Quantum™ Data Table (see “MODBUSAddressing Note” in the “Quantum™ Data Table” sectionof this manual for additional information). The Quantum™only accepts one value with a Load Register request.Changing a setpoint causes the Quantum™ to save thenew setpoint to nonvolatile memory. Be careful not tocontinuously request a setpoint change. Keeping theQuantum™ busy writing to memory will interfere with theQuantum™ communicating to its I/O boards. Acommunication failure to an I/O board will cause thecompressor to shutdown. For more detail and a list of thedata, reference the “Quantum™ Data Table” section ofthis manual. For details and information about the actualprotocol, reference the Modicon website athttp://www.modicon.com.

The read (query) and write examples on the followingpages are executed using a terminal emulation packageknown as Hyperterminal. For more information onHyperterminal, refer to the Hyperterminal section in thismanual. When using Hyperterminal, use the Frickaddresses listed in the address tables, rather than theModbus addresses. This is because Hyperterminal does

not use a Modbus driver as a protocol, but rather a pureASCII data packet. The Quantum™ however, does needto be set to Modbus protocol to properly interpret theASCII data.

Port Configuration of The Master

7 Bits per Character (Data Bits)No Parity1 Stop BitNo Handshake

Data Packet

The Modbus protocol establishes the format for theMaster's query by creating a message (data packet) asfollows:

• Assign the device address (Quantum™ panel ID#). The address field of a message framecontains two characters (ASCII). ValidQuantum™ device addresses are in the range of01 – 99 decimal. A master addresses aQuantum™ by placing the Quantum™ address inthe address field of the message. When theQuantum™ sends its response, it places its ownaddress in this address field of the response tolet the Master know which Quantum™ isresponding.

• A function code defining the requested action(Query):

• Function Code 3 - to read holding registers(sends a request to read data from theQuantum™).

- OR -

• Function Code 6 to load a register (to request tochange a setpoint or to send a command such asstarting the compressor).

• Any data to be sent (Response). The data field isconstructed using sets of two hexadecimal digits,in the range of 00 to FF hexadecimal. These areto be made from a pair of ASCII characters. Thedata field of messages sent from a Master to theQuantum™ devices contains additionalinformation which the Quantum™ must use totake the action defined by the function code. Thiscan include items like discrete and registeraddresses, the quantity of items to be handled,and the count of actual data bytes in the field. Ifno error occurs, the data field of a response froma Quantum™ to a Master contains the datarequested. If an error occurs, the field containsan exception code that the Master applicationcan use to determine the next action to be taken.

• An error-checking field.

The Query

The function code in the query tells the addressedQuantum™ what kind of action to perform. The data bytescontain any additional information that the Quantum™ willneed to perform the function. For example, function code03 will query the Quantum™ to read holding registers andrespond with their contents. The data field must containthe information telling the Quantum™ which register to


start at and how many registers to read. The error checkfield provides a method for the Quantum™ to validate theintegrity of the message contents.

The Response

If the Quantum™ makes a normal response, the functioncode in the response is an echo of the function code in thequery. The data bytes contain the data collected by theQuantum™, such as register values or status. If an erroroccurs, the function code is modified to indicate that theresponse is an error response, and the data bytes containa code that describes the error. The error check fieldallows the master to confirm that the message contentsare valid.

Data Field

The data field is constructed using sets of twohexadecimal digits, in the range of 00 to FF hexadecimal.These can be made from a pair of ASCII characters.

The data field of messages sent from a master to theQuantum™ devices contains additional information whichthe Quantum™ must use to take the action defined by thefunction code. This can include items like discrete andregister addresses, the quantity of items to be handled,and the count of actual data bytes in the field.

For example, if the master requests a Quantum™ to reada group of holding registers (function code 03), the datafield specifies the starting register and how many registersare to be read.

If no error occurs, the data field of a response from aQuantum™ to a Master contains the data requested. If anerror occurs, the field contains an exception code that theMaster application can use to determine the next action tobe taken.

Error Checking

When data is transmitted to and from the Quantum™Controller, each message has an Error Checking valueappended to the end of the message. Because theQuantum™ utilizes Modbus ASCII protocol, LongitudinalRedundancy Check, or LRC, is used as the method forverifying that the message sent from the transmittingdevice, was properly received by the receiving device.

The Longitudinal Redundancy Check (LRC) field is onebyte, containing an eight-bit binary value. The LRC valueis calculated by the transmitting device, by adding togethersuccessive eight-bit bytes of the message, discarding anycarries, and then two's complementing the result. It isperformed on the ASCII message field contents excludingthe colon character that begins the message, andexcluding the CRLF pair at the end of the message. TheLRC is then appended to the message as the last fieldpreceding the CRLF (Carriage – Line Feed) characters.Each new addition of a character that would result in avalue higher than 255 decimal simply rolls over the field'svalue through zero. Because there is no ninth bit, the carryis discarded automatically.

The receiving device recalculates an LRC during receipt ofthe message, and compares the calculated value to theactual value it received in the LRC field. If the two valuesare not equal, an error results.

ASCII Framing

In ASCII mode, messages start with a colon ( : ) character(3A hex), and end with a carriage return-line feed (CRLF)pair (0D and 0A hex).

The allowable characters transmitted for all other fields arehexadecimal 0 - 9, A - F.

All Quantum™ panels connected to the network monitorthe network bus continuously for the colon character.When one is received, each Quantum™ decodes the nextfield (the address field) to find out if it is the addresseddevice.

A Modbus message is placed by the transmitting deviceinto a frame that has a known beginning and ending point.This allows receiving devices to begin at the start of themessage, read the address portion and determine whichdevice is addressed, and to know when the message iscompleted. Partial messages can be detected and errorscan be set as a result.

A typical message frame as sent by the Master is shownbelow.

Query (Read) Example:

To demonstrate how an address within the Quantum™may be read, the following test can be performed usingWindows HyperTerminal:

As an example, a Modbus command will be created, andsent to obtain the actual Outside Air Temperature value ofAir Handling Unit #1. Using the address tables found laterin this manual, locate the address for Unit 1 Outside AirTemperature Analog Input. In this case, it would be Frick

Address 158 (decimal). Since this is the only address weare interested in obtaining the value of, send the followingmessage:

Look at this message on a more basic level, to understandhow the address that we are requesting is arrived at.


The first part of the message will be a Colon ( : ). Thisrepresents a “heads up” alert that data is coming “downthe line”.

Any time that a message is sent, all of the Quantum™panels that are on the Modbus network will become active, communications wise, once the Colon appears. Next, allpanels will look at the first byte following the Colon ( : ). Ifthis byte equals the Panel ID # of the particularQuantum™ being queried, it will immediately finishreading the remainder of the message. If the byte does notequal its ID #, the message will be ignored.

In this particular example, we are strictly looking to requestto view a data value, so we will be performing a readfunction (03):

158 decimal equals 9E hex. Looking at our example, wesee that we need a H.O. (High Order) address and a L.O.(Low Order) address. Since all data sent and received is inASCII Hex Byte format, we need to look at 9E Hex as theLow Order portion of the address. The High Order portionis 00. Now our decimal 158 is formatted as 009E Hex.

Since we are only looking for this one address, and noother, we can say that we are only looking for one DataAddress. Our Data Address part of the data packet is alsolooking for a High and a Low Order value. Fortunately, thenumber one (1) is the same in decimal as it is in Hex,therefore, the Low Order Address is 01 (hex). The HighOrder Address is 00 (hex), so our decimal 1 is formattedas 0001 (hex).

In order to ensure that the Quantum™ in questionreceives the data request accurately, we must append anError Check byte to the end of the message. This isaccomplished by adding each of the byte pairs (hex) thatwe have generated thus far:

01 + 03 + 00 + 9E + 00 + 01 = A3 hex

Next, subtract A3 (hex) from 100 (hex):100 (hex) – A3 (hex) = 5D (hex)

Write Example:

NOTE: To perform write functions to the ACUair®

Quantum™, the Panel Control Status (Frick® address 31)must be set to Remote. This can be done at the panel, orthrough communications. The Panel Control Status is theonly ACUair® address that can be written to without thepanel having to already be in remote.

To demonstrate how an address within the Quantum™may be written to, the following test can be performedusing Windows HyperTerminal:

As an example, a Modbus command will be created, andsent to set the Quantum™ to set the “Unit 1 ProcessControl Setpoint” to 25.0° C. First, be aware that data sentto and received by the Quantum™ has one decimal placeassumed. This means that to send the value of 25.0, youactually need to send 250. Using the address tables foundlater in this manual, locate the address for the “Unit 1Process Control Setpoint”. In this case, it would be Frick

Address (decimal). Since this is the only address we areinterested in writing to, send the following message:

Look at this message on a more basic level, to understandhow the address that we are writing to is arrived at. Wewant to send the value of 250 (25.0) to the Unit 1 ProcessControl Setpoint, Frick Address 309 (decimal).

The first part of the message will be a Colon ( : ). Thisrepresents a “heads up” alert that data is coming “downthe line”.

Any time that a message is sent, all of the Quantum™panels that are on the Modbus network will become active,communications wise, once the Colon appears. Next, allpanels will look at the first byte following the Colon ( : ). Ifthis byte equals the Panel ID # of the particularQuantum™ being queried, it will immediately finishreading the remainder of the message. If the byte does notequal its ID #, the message will be ignored.

In this particular example, we are strictly looking to write adata value, so we will be performing a write function (06):

309 decimal equals 135 hex. Looking at our example, wesee that we need a H.O. (High Order) address and a L.O.(Low Order) address. Since all data sent and received is inASCII Hex Byte format, we need to look at 35 Hex as theLow Order portion of the address. The High Order portionis 01. Now our decimal 309 is formatted as 0135 Hex.

The value that we wish to send is 25.0 (250). Our DataValue part of the data packet is looking for a High and aLow Order value. The number 250 (dec) must beconverted to hexadecimal. This conversion results in 03FA(hex). Separating 00FA into two bytes results in the LowOrder Value of FA (hex) and the High Order Value of 00(hex):

In order to ensure that the Quantum™ in questionreceives the data request accurately, we must append anError Check byte to the end of the message. This isaccomplished by adding each of the byte pairs (hex) thatwe have generated thus far:

01 + 06 + 01 + 35 + 00 + FA = 137 hex

Normally, we would subtract 137 (hex) from 100 (hex), asin the previous read example. However, in this case wesee that 137 hex is greater than 100 hex. Since the mathin this particular example would yield a negative number(FFFFFFC9), we need to modify the value of 137 in orderto provide a positive result. This is accomplished quitesimply by dropping the most left hand digit (137 becomes37):

100 (hex) - 37 (hex) = C9 (hex)

After the entire data packet has been created, simplypress the [Enter] key, a Line Feed will automatically besent also.

Response Example:

Using the Query (Read) Message example used earlier, ifthe packet was properly received by the Quantum™, youshould see an immediate response in HyperTerminal. Inthe Query Response (read function) example used earlier,a response of :01030200DC1E (hex) was received.

Once again, the first part of the message will be a Colon( : ). This represents a “heads up” alert that data is coming“down the line”, but since the data is coming from theQuantum™ to the Master this time, the Master will acceptit.

After having received the Colon ( : ), the Master will look atthe two bytes that follows it, so that it may determine fromwhich Quantum™ the message is coming from.

Now that the Master knows which panel is responding, itneeds to known which function the panel is responding to.In this case, it sees that it is a read function, and theQuantum™ is merely returning a value that was previouslyrequested.

The next byte tells the Master how many bytes ofinformation are being returned as a response. In this case,there are two (2) bytes of valid data.

The next two bytes (in this case) are the actual data inresponse to our original request.

We need to know what this value means. To break itdown, we must convert the pair of bytes from Hex toDecimal:

00DC (hex) = 220 (decimal)

Data to and from the Quantum™ are integer values withone decimal field assumed unless shown otherwise or thecommand is sent to select two decimal fields.

From the previous paragraph, we can assume that there isone decimal place to be applied to the data value that wasreturned. Therefore:

220 (decimal) = 22.0 (decimal)

All temperatures are in degrees C and all pressures are inPSIA unless the command is sent to select the units of thepanel. Therefore:

22.0 (decimal) = 22.0 C

Therefore, the value of the Outside Air Temperature forUnit 1 is 22.0° C.

NOTES:

This has been an example of how the Quantum™Controller uses the Modbus Protocol. It is hoped that theinformation provided here will assist the end user in writingapplications that will allow the Quantum™ to beimplemented into networks that the customer may alreadyhave in use.

This information is subject to change at any time, and isprovided as a reference only. Not all areas of the ModbusProtocol can be handled in this document. Someadditional information regarding Modbus Protocol that theend user should be aware of:

• There are many versions of Modbus Protocol thatis available, and an application that worksproperly on one system, may not functionidentically on another.

• Some versions of Modbus Protocol may requirethe user to increment any referenced addressesby “1” (one). For instance, if you wanted to lookat Frick Address 135, you may need to actuallylook at address 136. The Quantum™ addressingbegins at 0 (zero), whereas some ModbusProtocols begin at 1 (one), therefore, you mayneed to compensate.

• DO use Modbus ASCII. DO NOT use ModbusRTU.

• Use 7 Data bits.

• Follow the Frick specifications for datacommunications requirements.

HYPERTERMINALHyperTerminal is a terminal emulation program whichresides in the MicroSoft Windows environment, and assuch, will normally be found on any computer that isrunning Windows 95 or NT. HyperTerminal provides amethod by which the end user may verify conclusively thattheir Quantum™ controller is functioning properly, and asdesigned, with respect to external communications toremote devices.

Many times, the Quantum™ controller will be installed intoan environment whereby the end user wishes tocommunicate to it, either through a PLC (ProgrammableLogic Controller), a desktop computer for the purpose ofmonitoring/controlling plant operations through HMI(Human Machine Interface), or any number of othercommunications applications.

The purpose of this desired communications typicallyinvolves viewing and changing setpoints, starting andstopping a compressor, viewing alarm and shutdowninformation, and viewing current operating conditions.

When first connecting a Quantum™ panel to acommunications network, it would be highly desirable todetermine that all necessary parameters (jumper settings,panel setup, and cabling) are properly met so thatcommunications may be established quickly with theQuantum™, so that time is not lost in trying totroubleshoot a potentially simple problem.

A modem or direct connection from a Comm port of acomputer running Windows 95, or NT can be used toconnect to Com-2 of the Quantum™.

Setting up Hyperterminal

You will need to locate either a lap top or desktopcomputer, that has Hyperterminal installed.

• Turn on the power for the lap top.

• After the laptop has fully booted, locate theHyperterminal program. (Hyperterminal is usuallyfound in the “Accessories” folder). IfHyperterminal can't be found there, try using the“Find File” command, and search the entire harddrive.

• Be aware that the screens that are actuallyshown on the test computer may or may notappear exactly as shown here. Various versionsof Windows, can affect the appearance, as wellas whether or not the screen has been“maximized”, or if it has been scaled to a smallersize. Regardless of how the screen workappears, the function of the screen work is whatis important, and that function is not affected bythe way the screen looks.

• Once Hyperterminal has been located, execute it.A dialog box will appear. You will be prompted toenter a name for the “New Connection”. Type inwhatever name you would like to use, “Frick”was used in this example. This name will alsocreate a file once you are finished, saving all ofthe setup parameters for future use. It isrecommended that a name be chosen to reflectthe type of Protocol that you will be using as youmay wish to setup for various protocols. Onceyou have entered a name, click [OK].


A new dialog box will be shown asking to select a Comport (choose the Com port that your communications cable

is attached to, this will normally be Com-1). The phonenumber box should be blank. Click on [OK].

The Com-1 properties dialog box will now appear. Theparameters in this box must match the requirements of theprotocol that you are wishing to use. The one box thatnormally would need to be changed from one protocol tothe next is the “Data Bits ” box. For Modbus, you wouldwant to use 7 data bits, for Frick and Quantum™protocols, use 8 data bits.

NOTE: Allen-Bradley protocol cannot be tested usingHyperterminal.

For the purpose of this document, Frick “#” protocol willbe used. Refer to the Modbus section of this manual forinformation on Modbus.

Set the five boxes as follows, then click [OK].

• Bits per second: 9600 (must match theQuantum™)

• Data bits: 8

• Parity: None

• Stop Bits: 1

• Flow Control: None


The following screen will appear. This is the screenwhereby all communications (out of the computer, and intoit) will be shown. When valid data is typed in here, then

sent, the connected device recognizes and responds tothat data, and a response will be shown below the sentdata. Click on [File].

A pull down menu will appear. From this menu, locate andclick on [Properties]. You will once again see the

following screen. This time, click on the [Settings] tab.


The computer will need to be set up to match thedocumentation as presented here, for everything to look

and work as shown later. To do this, click on the [ASCIISetup…] button.

On the ASCII Setup screen, for best results, check theboxes according to the following chart:

For Modbus:

• Send line ends with line feeds• Echo typed characters locally• Append line feeds to incoming line ends• Wrap lines that exceed terminal width

For Frick® protocols (# and $):

• Echo typed characters locally• Append line feeds to incoming line ends• Wrap lines that exceed terminal width

Leave everything else on this dialog box unchanged, thenclick on [OK].


The Properties screen will once again be shown. Click onthe [OK] button to proceed.

You will now be back to the main Hyperterminalcommunications screen. This screen will be blank. Allcommunications, both from the computer, and to the

computer (from the Quantum™), will appear on thisscreen. Proceed to the “Testing Communications” section.


Testing Communications

Set the keyboard for “CAPS” (so that all capital letters will

be typed). Type in the following command: #01I, thenpress [ENTER]. (This command will request theQuantum™ with ID 01 to send a packet of Information.)

If the communications is working properly, there should bean immediate response from the first Quantum™. Theresponse should look something (but not necessarilyexactly) like “#01I000AOMN609”

Go to the first Quantum™ in line, and check the "ShowComms" screen that was described earlier. You shouldsee your message (and the Quantum™ reply) displayedthere.

If this portion of the test has passed, you can try tocommunicate to the next (or any Quantum™, by changingthe value that you type into the HyperTerminal screen asfollows:

Instead of [#01], replace the “01” portion with the IDthat you would like to access. For instance, if youwanted to talk to a fourth Quantum™ (ID 4), type in[#04]. This should return a message from thatQuantum™.

This has been just a brief description of how to check yourcommunications and verify that it is working. Greater detailcan be found by consulting tables for each of the protocolsin this manual.

General Notes:

Ensure that the Quantum™ is set for the correct IDnumber, BAUD rate and type of communications protocolthat is to be used. This setup can be found by pressing the[Menu] key on the keypad, then pressing the [PanelSetup] key that will appear at the right side of the display.When the panel setup appears, look at the information atthe “CHANGE COMMS” line of the screen. This info mustmatch the communications that you are trying to establishat the other end.

There are two red LED’s associated with the Com-2 porton the Quantum™ (TX2 & RX2). Ensure that neither ofthese LED’s are on continuously. If one or the other (orboth) are on constantly, disconnect the Com cable. If thestatus of the LED’s does not change, check the wiringconnections to the communications port. Ensure that thewiring is not backwards. If the wiring is correct, power theQuantum™ down, then back up. If either or both of theLED’s is still on, a bad driver chip may be suspected onthe Quantum™, and the board should be replaced.

Once everything has been inspected (cables, jumpers,and setup), try to develop communications from themaster. You should see the LED’s on the Com-2 portflickering as the Quantum™ “talks” to the master. Ifnothing happens, it would be best to consult the“HyperTerminal” section of this memo for more detailedtroubleshooting.

If you do see the LED’s flickering, but data at the masterdevice does not look correct, you can verify what is beingsent and received at the Quantum™ by:

Pressing the [Menu] key on the keypad, then whenthe "Main Menu" screen appears, find and press the[MORE…] button.

A second "Main Menu" screen will appear. Find andpress the [Service Screen] key


The “Service Screen” will appear. Press the [ShowComms] key at the top right of the screen to view thecommunications information.

You will now be viewing all of the communicationsinformation that Com-2 is receiving and transmitting. Thisscreen will require you to update it manually be pressingthe [Show Comms] key periodically.

This screen will display all data that is coming through theCom ports. At the left of each line, you should see whetherthe data is “IN” or “OUT” (Receive or Send). Followed by“COMM X” (which com port of the Quantum™ is doing the“talking”). And lastly, the actual data (in Hexadecimalformat).

Ensure that this Hex data matched the data at the master.Refer to the “Conversion Chart For Decimal / Hexadecimal/ ASCII” in this manual for assistance in decoding thecommunications data.

If no data appears, or if the data does not match thespecific protocol requirements that you are using, then oneof the following things can be the problem:

• Wiring problem. (verify that the wiring matchesthat shown in the

• Quantum™ Panel Setup is wrong. Access thePanel Setup screen and verify that theQuantum™ ID is set to the same value that youare trying to access. Also, check that the baudrate matches that of the setup in the propertiessection of the Hyperterminal example.

• Quantum™ jumpers. Verify the position of thejumpers by comparing them with the sectionentitled “Quantum™ 3 Communications Jumpers”for the Quantum™ 3, or entitled “Quantum™ 4Communications Jumpers”, for the Quantum™ 4.

• Incorrect data is being entered in Hyperterminal.Ensure that the data that you have entered,exactly matches the example. Use capital letters.

• Go back through the “Setting up Hyperterminal”section, and ensure that it has been followedexactly. Repeat the process if necessary.

• If you are using a converter card (to convert theRS-232 signal from the computer to RS-422 orRS-485), then either verify that the converter cardis working properly with a different piece ofknown functioning equipment, or eliminate itcompletely by tying into the Quantum™ directlythrough RS-232.

• The Communications port on the computer isbad. Try to verify this by communicating to adifferent piece of known good equipment.

• The Communications port on the Quantum™ isbad.


Quantum™ Data Table

Allen-Bradley and Modbus Data Access

Data passed to and from the Quantum™ are integervalues with one decimal field assumed unless shownotherwise or the command is sent to select two decimalfields. For example, if the data’s value is 25.5 then thevalue 255 is sent. All temperatures are in degree C and allpressures are in PSIA unless the command is sent toselect the units of the panel. . A mode such as “CurrentACUair Mode” is sent as an integer value that representsthe 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” statusand a “DISABLED” option. The value one (1), which isreceived as a 10, is used to represent an “ON” status andan “ENABLED” option. Only data values that aredesignated as setpoints are modifiable. “Read Only” isused to help identify what data is not modifiable. Thesetpoint range is checked to see if it is an allowed setting.If it is not allowed, the setting is not changed. Referencethe “Frick ACUair Quantum™ Control PanelMaintenance” S90-500 M for the setpoints default settingsand ranges. Reference the “Quantum™ Data Table” in thismanual for the address listing and description of data.

A command has been provided that selects whether datato and from the Quantum™ will be integer values witheither one or two decimal fields assumed. Anothercommand has been provided that selects whether data toand from the Quantum™ will be returned in the units thatare the default (pressure in PSIA and temperature inDegree C) or in the units that are selected to display at thepanel.

With the ACUair® control system, all unit-specific setpointsare stored at the GCU board and are only loaded to theQuantum panel as needed. As a result, delays will beencountered when reading or writing these setpoints asthe values are transferred between the Quantum and GCUboard. 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 setpointsstored at the GCU, it is necessary to follow certainprocedures. First, a command should be sent to changethe Panel Control Status to “Remote”. The Quantumscreen will immediately move to the Unit Overview displayand the Panel Control Status will be set to Remote. At thispoint, a command may be sent to read or write setpointvalues.

When using the Modbus protocol, expect to wait a up toseveral seconds while the required values are downloadedfrom the GCU board. With the Allen-Bradley protocol, thefirst time a value or set of values are requested, no data isreturned, but the data is downloaded from the GCU board.The same data request should be sent several secondslater, and the downloaded data will now be returned.When setpoints are changed, the Quantum will reply to theAllen-Bradley or Modbus command and then write thechange to the GCU board. After sending a writecommand, wait approximately a second before sendingthe next command. These operational methods, whenused properly, allow a person to make a large number ofsetpoint changes without stalling communications.

When reading values from the GCU board that maychange periodically, such as the Alarm List, send theRefresh Setpoints command before reading the values toverify that current settings are being read. Also be aware,if a person presses the "Login to Unit" button at theQuantum, the Panel Control Status setting will be set toManual. This will prevent a remote system from reading orwriting the setpoints until the Panel Control Status is resetto Remote.

Modbus Addressing Note:

When using Modbus protocol (other than theHyperterminal example shown earlier), it is necessary touse the Modbus Address as shown in the following tables.These addresses should work for most applications.

4500 N25:0 Unit 1 Alarm list (See Following Note)




Alarm list Note: The read request returns three values for each alarm. The alarm code, the hour the alarm occurred,and the minutes after the hour the alarm occurred. If the alarm code is 0, the hour and minutes are not relative. Themaximum number of alarms that can be requested is 18. The message size value determines how many alarms arereturned. Multiply 3 times the number of alarms to be requested and enter this number as the size of the message.For example, if the data of 18 alarms is desired, set the message size to 54 Reference the numerical listing of thealarm codes in this manual.


Alarm List 2 (read only):Some systems cannot handle all alarms being returned under one address. To accommodate these systems, the Alarm List isalso broken down into individual addresses. (Refer to the address table below for the specific addresses.)

With regard to the Alarm List, the ACUair® Quantum™ is capable of displaying the most recent 18 alarms, as well as the hour,minute and date that each alarm occurred. Each alarm is now accessible independently. For instance, reading Frick® Address4600 will return the value of the most recent alarm code. This code value will correspond to the ALARMS/SHUTDOWNSMESSAGE CODE near the back of the Communications Setup manual. Reading the next address (4601) will return the hoursinteger (0 to 24) and the following address (4602) will give the minutes integer (0 to 59). It should be pointed out that an alarmcode of zero indicates that there is no alarm in that message slot. Although no alarm is present, there is a still a time stampreturned. Simply ignore this time stamp.

Quantum™ 3 Main Board History andIdentification

The processor board shown on this page is known as theQuantum™ 3 and has been in production since January2000. Frick® Company developed this board as thesuccessor to the Quantum™ 1 & 2 and it is based on thePentium microprocessor platform.

The Quantum™ 3 board can be identified by the presenceof a “piggy back” daughter board mounted to the mainboard. This “daughter board” can be easily identified bythe presence of a large black heat sink mounted on themain processor chip. There are also a number of jumpers(or links) present on this smaller board. It is NOT advisedto modify these jumpers.

The main board (communications board) has a 2-digit LEDdisplay (which during normal operation, will display aconstantly changing pattern of values), an 8 position DIPswitch pack on the main board, and a number of jumpers(or links). The links on this main board MAY need to bemodified by factory qualified personnel to configure the

Quantum™ for specific applications. Refer to the nextpage for more details on the settings of these “Links”.

Unlike the Quantum™ 1 & 2, which utilized EPROMS forthe Operating Software, the Quantum™ 3 utilizes FlashCard technology. There is a Flash Card socket located onthis main board. The Operating System has been pre-loaded at the factory, so this Flash Card feature willprimarily be utilized for future program updates.

When calling Frick Company for service or help, it willgreatly assist us if the type of board is known, eitherQuantum™ 1, 2 , 3 or 4. Additionally, Frick will requestthe Sales Order number, and the Operating Systemversion number (this can be found on the Menu “About…”screen). The more information you have at the time of thecall, the better able we will be to assist you.

The information that follows will primarily describe thejumper configuration for communications settings, as wellas wiring diagrams for the different types ofcommunications that are possible with the Quantum™ 3.

Quantum™ 4 Main Board History andIdentification

The processor board shown on this page is known as theQuantum™ 4 and has been in production since October2001. Frick Company developed this board as thesuccessor to the Quantum™ 3 and it is based on thePentium microprocessor platform.

The Quantum™ 4 board can be identified by the presenceof a “piggy back” daughter board mounted to the mainboard. This “daughter board” is the communicationsportion of the Quantum™, and it can be identified by thepresence of an 8 position DIP switch. There are also anumber of jumpers (or links) present on this smaller board,as well as three green connectors (RS-232, RS-422 andRS-485 ports). The jumpers are used to set up thecommunications parameters that are listed on the nextpage.

The main board (larger of the two) has a number ofjumpers (or links) also. The links on this main board MAYneed to be modified by factory qualified personnel toconfigure the Quantum™ for specific applications. Refer tothe ACUair® Maintenance Manual (S90-500 M) for moredetails on the settings of these “Links”.

Unlike the Quantum™ 1 & 2, which utilized EPROMS forthe Operating Software, the Quantum™ 4 utilizes FlashCard technology, as did the Quantum™ 3. There is aFlash Card socket located on the under side of this mainboard. The Operating System has been pre-loaded at thefactory, so this Flash Card feature will primarily be utilizedfor future program updates.

When calling Frick Company for service or help, it willgreatly assist us if the type of board is known, eitherQuantum™ 1, 2, 3 or 4 (Quantum™ 3 is described in theprevious section). Additionally, Frick will request theSales Order number, and the Operating System versionnumber (this can be found on the “About…” screen). Themore information you have at the time of the call, thebetter able we will be to assist you.
