4 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 4 QUANTUM IDENTIFICATION Frick Controls has over the years, strived to remain on the cutting edge of microprocessor technology and development. Because of the ever-increasing speed, memory, features, and power of microprocessors, Frick Controls will continue to introduce the latest advancement in microprocessor control technology. Our microprocessor family has shared the name Quantum, over the past five years. There are currently four controllers within this family. The first two of these controllers (known as Quantum 1 and Quantum 2) are no longer in production, and as such, will not be further mentioned in this manual. The two current members in production of the Quantum family are the Quantum 3, and the Quantum 4. It is critical to the end user to be able to identify the differences between these controllers. Refer to the section in this manual entitled Quantum 3 Main Board History and Identification and Quantum 4 Main Board History and Identification for additional information as to how to identify the particular Quantum controller that you have. Throughout this manual, the two different controllers will be talked about for the most part as one (as they do function the same). Where there is a difference between these boards, as in jumpers or wiring, the different models will be identified by name. This is why it is important for you to be aware of which Quantum board you have. Quantum 3 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 master computer via either RS-422, RS-232, or RS-485 connections to the Quantum Com-2 port. Reference the Main Board Communications section for the correct jumpering of RS- 422, RS-232, or RS-485. Also, reference the drawing of the Quantum Main Board section to identify wiring configurations for Com-2. COM-2 PINOUTS FOR QUANTUM 3 Following is the RS-422, RS-485, and the RS-232 pin descriptions for communications port 2 (also referred to as Com-2 or Comm-2): RS-422 Pinout (4-Pin Connector) RS-485 Pinout (4-Pin Connector) 1 - RX (Receive) 1 - RX / - TX 2 + RX (Receive) 2 + RX / + TX 3 - TX (Transmit) 4 + TX (Transmit) RS-232 Pinout (10-Pin Connector) 1 Data Communication Device 2 Data Set Ready 3 Received Data 4 Request to Send 5 Transmit Data 6 Clear to Send 7 Data Terminal Ready 8 Ring Indicator 9 Ground 10 Not Used COM-2 PINOUTS FOR QUANTUM 4 Following is the RS-422, RS-485, and the RS-232 pin descriptions for communications port 2 (also referred to as Com-2 or Comm-2): RS-422 Pinout (4-Pin Connector) RS-485 Pinout (4-Pin Connector) 1 - RX (Receive) 1 - RX / - TX 2 + RX (Receive) 2 + RX / + TX 3 - TX (Transmit) 4 + TX (Transmit) RS-232 Pinout (3-Pin Connector) 1 Transmit Data 2 Received Data 3 Ground Quantum 4

Following is the pin positions of the 10-Pin connector: 9-Pin Connector 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. QUANTUM 4 Reference the drawing of the main processor board for the location and positioning of the 3-Pin RS-232 connector. Following is the pin positions of the 3-Pin connector: 9-Pin Connector RXD TXD COM RXD TXD COM RXD TXD COM COM RXD TXD Quantum 3 10-Pin Connector 1 2 Quantum 4 3-Pin Connector Converting an RS-232 Serial Port to RS-422 or RS-485 In order to communicate to the Quantum controller via RS-422 (or RS-485), you will need to convert the RS-232 signal 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 a standard RS-232 signal to either RS-422 or RS-485. The AC7A card is powered from a 115 VAC source, while the AC7B card is powered from a 220 VAC source. They can be used in a standalone panel along with an Allen Bradley SLC 5/04 or 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 NOTE: Refer to the manual that comes with the AC7A/B card for specific jumper information (as the configuration shown is only a suggestion that has worked in most applications). Once jumpers on the converter card have been verified, you will need to verify the jumper settings of the Quantum controller. Refer to the following diagrams for the Quantum 3 and Quantum 4: LK19 COM-1 RS-422 RS-485 COM-2 RS-422 RS-485 COM-2 RS-232 TB1 TB2 B A B A B A LK1 TB3 COM-2 RS-232 LK10 LK9 LK8 LK7 RX1 TX1 LK16 RX2 TX2 LK17 RX3 TX3 LK18 LK6 LK5 LK4 LK3 B A LK1 LK2 LK3 LK4 LK5 LK6 LK7 LK8 LK9 LK10 LK11 LK12 LK13 LK14 LK15 PORT D3 D2 COM-1 RS-422/RS COM-2 RS-422/RS-485 COM-3 (Future Use) Quantum 3 LK16 D1 D4 D5 D7 D8 D10 D11 D12 D13 LK17 B A Quantum 4 Verify the jumpers in this location. NOTE: Some of these jumper settings may need to be modified to ensure optimum communications performance. Typically, the termination jumper should be installed in the last Quantum in the communications daisy chain only (Link 7 for the Quantum 3, Link 1 for the Quantum 4).

8 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 8 Software Setup For The Communications Loopback Test On the Change Communications screen (shown above), ensure that the settings are as follows: ID Number: 0-99 (does not matter) Comm 1 Baud Rate: (does not matter, but it must be set the same as Comm 2 Baud Rate) Comm 2 Baud Rate: (does not matter, but it must be set the same as Comm 1 Baud Rate) Communication Protocol: Frick (must be Frick ) Performing the Communications Loopback test Upon properly setting up the Change Communications screen, access the Service Screen. The center of the screen will initially appear blank. The bottom key on the right side of this screen is the Comms Loopback Test key. Pressing the key will initiate the test. The blank center of the screen will be replaced by one of three word lines: Testing - This will appear as the test is running. NOTE: The test occurs so quickly that It may be possible that the word Testing will not appear if the test passes. Passed - If the test passes, the word Passed will appear. Failed - If the test does not pass, this will appear.

9 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 9 PROTOCOL DESCRIPTION The use of communication protocols, permits data transmission between devices. Protocol determines how contact is established and how the query (question) and response (answer) takes place. The information in a message command requires an identity of the intended receiver (ID #), what the receiver is to do (read or write to a setpoint, etc.), data needed to perform an action (the value of a setpoint to be changed), and a means of checking for errors (checksum). When using Com-2 for communication, check what communication protocol, if any has been selected, from the Panel Setup Change Communications screen. For example, [A-B Comm] should be selected when using Allen-Bradley s communication protocol. The baud rate of Com-2 and the panel ID number are also changed from this screen, 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 Controls for the exact details on your particular unit(s) before developing system software to interface with the panel. Protocols Quantum Communications Protocols The Quantum controller has the capability of communicating to the outside world through four software protocols: Frick Allen-Bradley DF-1 serial ModBus ASCII serial YORK ISN Note: When using Modbus protocol, a [Comm. 2 Advanced] key will appear. Pressing this key will allow the user to modify the number of Data and Stop bits, as well as Parity. This only applies to Modbus. Modbus cannot be changed from ASCII to RTU however. Refer to the section on Modbus for further information. 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 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 screen. For example, [A-B Comm] should be selected when using Allen-Bradley s communication protocol. 4. Setup the baud rate of Com-2 to coincide with the setup of the your device s communication port. 5. Enter the Quantum 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 Com-2 port. If you are communicating to more than one panel, then you will not be able to use RS 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.

10 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 10 Reference the drawing of the Quantum Main Board in this manual to identify wiring and jumpering locations for Com-2. Reference the Main Board Communications Com-2 section in this manual for the correct jumpering of RS-232, RS-422, or RS Send a single command to read data from this Quantum using its ID. 8. Check if you received a data response at your device. 9. Troubleshooting when you don t receive a data response: Check if Com-2 on the Operating Status screen 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 steady lit RX2 LED or one that isn t lighting, are signs of improper wiring. If the TX2 is not blinking then check the communication protocol setup at the panel, the panel s ID and the Com-2 baud rate setting. If the TX2 is blinking, then check that the Com-2 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 to see what is being received and transmitted from Com-2. Note: A useful tool for troubleshooting is Windows HyperTerminal. Using HyperTerminal can help you determine if you are wired OK. Reference the HyperTerminal Setup 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. To prevent noise feedback which is possible when communicating over a long distance, only the last panel should have the termination for long communications lines jumpered. If the RX2 LED is properly blinking, then check if the TX2 LED is blinking in response.

11 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 11 Frick Protocols All commands for Frick protocols must be in ASCII to be recognized (see the Conversion Chart For Decimal / Hexadecimal / ASCII, located later in this manual). The data should be setup as an 8 bit Word with no 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 # Protocol Specifications Frick # protocol consists of commands that are available for most other existing models of Frick control panels. The Frick # protocol does not utilize a checksum. It is better to use Frick Quantum ($) protocol when only communicating to Quantum panels. When there is more than one panel, a Quantum can be wired from it s Com-2 to another panels Com-2 or can be wired from it s Com-2 to Port 1 of a RWB, RDB, RXB or RXF Micro Plus panel. Frick RWB, RDB, RXB, or RXF Panel Frick # Communications Port #1 RS-422 Pinout 9 - TX (Transmit) 8 + TX (Transmit) 5 - RX (Receive) 4 + RX (Receive) The following is a complete list of available Frick Protocol # commands: COMMAND CODE and DESCRIPTION I = Returns compressor status information. R = Compressor start control. S = Compressor stop control. V = Slide Valve/Slide stop control. 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 is 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 returned in the current temperature units as 3 characters with no decimal position (i.e. 032 would represent 32 degrees Fahrenheit if the panel temperature units are in Fahrenheit, or it would represent 32 degrees Celsius, if the panel temperature units are in Celsius). Suction Temperature is returned as 4 characters with a + or - as the leading character (i.e. 010 would represent 10 degree). Pressure data is usually returned in the current pressure units. However, the Filter differential reading is always returned in PSIA. When in PSIG or in PSIA, the pressure data is returned as 3 characters with no decimal position. However; 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 characters 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: RETURN COMPRESSOR STATUS INFO: #01I # Start of command sequence. 01 Compressor ID code. I Return Status information command. RETURNED ANSWER, ie: 090RRRN340 Character Position Description of returned data 1, 2, 3 Slide Valve position. 4 Remote, Auto, Manual (Slide Valve) 5 Delay-recycle, Running, Off, Slide Valve too high, Permissive Start not enabled, d(i)fferential Pressure too high, s(t)opping, au(x) not energized 6 Rem, M Keypad, Auto (Compressor mode) 7 Cutout (Shutdown), Alarm, Normal 8, 9, 10 Suction in PSIA.

15 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 15 Quantum $ Protocol Specifications Quantum ($) 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 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 that it is in. For example, a is sent if it is in manual, or a is sent if it is in automatic, or a is sent if it is in remote. The value zero is used to represent an OFF status and a DISABLED option. The value one , 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. Reference the Frick Quantum Control Panel Maintenance publication S M for the setpoints default settings and ranges. 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 (refer to the Data Packet section for more information). If the Quantum detects a checksum error, a N (Not Acknowledged), the Compressor ID code, 02, Carriage return, and Linefeed are returned. This document will demonstrate how to communicate to the Quantum panel using the tables that appear on the following pages. Data Packet If you were interested in viewing the information that is displayed on the Operating Status - Page 1 screen (Home screen), you would want to refer to the table entitled RETURN OPERATING STATUS Page 1 data: $01D1 table on the next page. The quickest and easiest way to demonstrate this protocol is through Hyperterminal (see the section entitled Hyperterminal later in this manual). After setting up Hyperterminal and ensuring that all wiring and jumper configurations are correct, type a $ symbol. This is the character that will alert all of the Quantum panels on the communications line that data is on its way. Following the $ symbol, type the ID code of the Quantum that you wish to query (for instance 01 for the first Quantum ). After the ID number, type a D1. The protocol code in the Quantum recognizes this portion of the data packet as a request for the data that is displayed on the Operating Status - Page 1 screen. Up to now you have typed the following information: $01D1. The next thing that must be done is to enter a checksum value. You may elect to type in a?? as a wildcard if you do not have the time to figure the correct checksum, however, the information that is returned may or may not always be reliable. The checksum will ensure reliability. To arrive at the checksum value for the command you have just typed, you will need to convert each ASCII digit into hexadecimal (do not include the $ symbol). For this example, you will need to take the first digit 0, and referring to the Conversion Chart at the end of this section, look down the ASCII column until you find 0. You will notice that the Hexadecimal equivalent for ASCII 0 is 30 hex. Repeat the process of looking up each digit in the ASCII column, and finding its equivalent in the Hexadecimal column, and write each value down. When all four digits (01D1) have been converted to hexadecimal, you will need to add the four values together. Remember, the values are in hexadecimal format, not decimal. If you are not familiar with hexadecimal math, you may wish to utilize the calculator that comes with Microsoft Windows. Look at the following chart: ASCII Value of Data Packaet Hexadecimal Equivalent D Hex Total = D6 The answer that is arrived at from the previous chart is D6. This will become the checksum for the data packet, and is appended to the end of the data that has so far been typed in. NOTE: For any calculation that results in an answer of more than two digits, use only the right most two digits, and disregard all digits to the left. The result should look like this: $01D1D6 Press the [Enter] key. You should see an immediate response. The format of this response should resemble something (but not necessarily exactly) like: A B6 Referring to the RETURN OPERATING STATUS Page 1 data: $01D1 table on the next page, we find that the first line of the response, A01, indicates that an Acknowledgement (A) was received from device 01 (01). This is followed by (Suction Pressure). The plus (+) symbol indicates a positive value, followed by Since there are two decimal positions assumed, equals PSIA. Using the +/- symbols as a delimiter in the above example, each section of 8 digits can be interpreted by comparing it with the Operating Status table. The B6 value at the very end of the response is the checksum value that the Quantum returned, not actual data.

24 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 24 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 Master / Slave multi-drop communication method. The Quantum talks Allen-Bradley SLC protocol and is programmed to resemble an Allen-Bradley SLC500 slave station. The customer s PLC or DCS must be setup to 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 its 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 with 3 address fields and protected typed logical write requests with 3 address fields to a Quantum. Fifty (50) data elements can be read with one read. The most desired data (information on the Operating Status screen) exists in a fifty (50) element data area. Setpoints are changed by sending a write command to one element. Changing a setpoint causes the Quantum to save the new setpoint to Flash memory (non-volatile memory). Be careful not to continuously request a setpoint change. It is to be expected that communications may slow down during the process of writing setpoints or clearing alarms. Both of these processes involve writing to either EEPROM or Flash Memory and does take some time. If communication requests are being sent faster than once every couple of seconds, there will be temporary slowdowns during these processes. Additionally, keeping the Quantum busy writing to Flash memory will interfere with the Quantum communicating to it s I/O Boards. A communication failure to an I/O board will cause the compressor to shutdown. Control commands such as starting the compressor 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 DF1 Protocol and Command Set Reference Manual. Because overrun can occur, the baud rate and commands should 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 Error Detect set for BCC or CRC. 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 Master to give each of them polling permission to transmit in a timely manner. As the number of Quantum slaves increase on the link, the time between when each 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. 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 master station will wait after receiving an ACK (to a master-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 the instruction timed out. A timeout of 0 seconds means that there is no timer and the message will wait indefinitely for a reply. Valid range seconds. Note: Make sure the Allen-Bradley PLC and the programming software is the most recent software revision. Some revisions have been made that do not allow the SLC Typed Logical Read/Write Message Command.

31 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 31 MODBUS Protocol Since Modbus protocol is a messaging structure, it is independent of the underlying physical layer. It is traditionally implemented using RS-232, RS-422, or RS- 485 communications hardware. The Quantum controller is setup to communicate on standard Modbus networks using ASCII (American Standard Code for Information Interchange). NOTE: With the Quantum Controller, ONLY Modbus ASCII (7 or 8 data bits) is recognized, and all references to Modbus protocol in this document will be as they relate to ASCII. The mode and serial parameters must be the same for all devices on a Modbus network, therefore, ensure that your network is utilizing the Modbus ASCII protocol before attempting to try to communicate to the Quantum portion of the network. Additionally, typical Modbus protocols allow for network broadcasting, whereby a single message can be sent to all devices simultaneously. This Broadcasting is NOT allowed or supported by the Quantum Controller. The Quantum provides the capability to interface with other devices that support serial data communications using the Modbus ASCII protocol. This is a Master / Slave multi-drop communication method whereby the Quantum is setup to be a Modbus ASCII Slave. The customer s PLC (Programmable Logic Controller) or DCS (Data Communications System, such as a desktop or laptop computer) must be setup as a Modbus ASCII Master. The Master initiates the reading and writing of data (queries) to a Quantum. The Quantum does not generate its own data, it will only reply from a request by the Master. The Quantum ID number is used as the Modbus Slave address. The Master uses Function Code 3 (Read Holding Registers) to send a request to read data from the Quantum. The Master uses Function Code 6 (Load Register) to request to change a setpoint or to send a command such as starting the compressor. Up to fifty (50) data elements can be read with one read request. The most desired data (information on the Operating Status screen) exists in a 50 (fifty) element data area. The address references are numbered relative to the Frick addresses in the Quantum Data Table (see MODBUS Addressing Note in the Quantum Data Table section of this manual for additional information). The Quantum only accepts one value with a Load Register request. Changing a setpoint causes the Quantum to save the new setpoint to nonvolatile memory. Be careful not to continuously request a setpoint change. Keeping the Quantum busy writing to memory will interfere with the Quantum communicating to its 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 of this manual. For details about the actual protocol, reference the Modicon website at Port Configuration of The Master 7 or 8 Bits per Character (Data Bits) Odd, Even or No Parity 1 or 2 Stop Bits No Handshake Data Packet The Modbus protocol establishes the format for the Master's query by creating a message (data packet) as follows: Assign the device address (Quantum panel ID #). The address field of a message frame contains two characters (ASCII). Valid Quantum device addresses are in the range of decimal. A master addresses a Quantum by placing the Quantum address in the address field of the message. When the Quantum sends its response, it places its own address in this address field of the response to let the Master know which Quantum is responding. A function code defining the requested action (Query): Function Code 3 - to read holding registers (sends a request to read data from the Quantum ). - OR Function Code 6 to load a register (to request to change a setpoint or to send a command such as starting the compressor). Any data to be sent (Response). The data field is constructed using sets of two hexadecimal digits, in the range of 00 to FF hexadecimal. These are to be made from a pair of ASCII characters. The data field of messages sent from a Master to the Quantum devices contains additional information which the Quantum must use to take the action defined by the function code. This can include items like discrete and register addresses, the quantity of items to be handled, and the count of actual data bytes in the field. If no error occurs, the data field of a response from a Quantum to a Master contains the data requested. If an error occurs, the field contains an exception code that the Master application can use to determine the next action to be taken. An error-checking field.

32 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 32 The Query The function code in the query tells the addressed Quantum what kind of action to perform. The data bytes contain any additional information that the Quantum will need to perform the function. For example, function code 03 will query the Quantum to read holding registers and respond with their contents. The data field must contain the information telling the Quantum which register to start at and how many registers to read. The error check field provides a method for the Quantum to validate the integrity of the message contents. The Response If the Quantum makes a normal response, the function code in the response is an echo of the function code in the query. The data bytes contain the data collected by the Quantum, such as register values or status. If an error occurs, the function code is modified to indicate that the response is an error response, and the data bytes contain a code that describes the error. The error check field allows the master to confirm that the message contents are valid. Data Field The data field is constructed using sets of two hexadecimal 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 the Quantum devices contains additional information which the Quantum must use to take the action defined by the function code. This can include items like discrete and register 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 read a group of holding registers (function code 03), the data field specifies the starting register and how many registers are to be read. If no error occurs, the data field of a response from a Quantum to a Master contains the data requested. If an error occurs, the field contains an exception code that the Master application can use to determine the next action to be taken. Error Checking When data is transmitted to and from the Quantum Controller, each message has an Error Checking value appended to the end of the message. Because the Quantum utilizes Modbus ASCII protocol, Longitudinal Redundancy Check, or LRC, is used as the method for verifying that the message sent from the transmitting device, was properly received by the receiving device. excluding the CRLF pair at the end of the message. The LRC is then appended to the message as the last field preceding the CRLF (Carriage Line Feed) characters. Each new addition of a character that would result in a value higher than 255 decimal simply rolls over the field's value through zero. Because there is no ninth bit, the carry is discarded automatically. The receiving device recalculates an LRC during receipt of the message, and compares the calculated value to the actual value it received in the LRC field. If the two values are 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 are hexadecimal 0-9, A - F. All Quantum panels connected to the network monitor the network bus continuously for the colon character. When one is received, each Quantum decodes the next field (the address field) to find out if it is the addressed device. A Modbus message is placed by the transmitting device into a frame that has a known beginning and ending point. This allows receiving devices to begin at the start of the message, read the address portion and determine which device is addressed, and to know when the message is completed. Partial messages can be detected and errors can be set as a result. A typical message frame as sent by the Master is shown below. START ADDRESS FUNCTION DATA LRC CHECK END : CRLF 1 CHAR 2 CHAR 2 CHAR 8 CHAR 2 CHAR 2 CHAR Where : = Start of Message 01 = Quantum ID 03 = Read Function 00 = H.O. address (hex) 87 = L.O. address (hex) 00 = H.O. # of Data Registers 01 = L.O. # of Data Registers 74 = Error Correction Code CRLF = Carriage Return Line Feed The Longitudinal Redundancy Check (LRC) field is one byte, containing an eight-bit binary value. The LRC value is calculated by the transmitting device, by adding together successive eight-bit bytes of the message, discarding any carries, and then two's complementing the result. It is performed on the ASCII message field contents excluding the colon character that begins the message, and

Using the address tables found later in this manual, locate the address for Discharge Pressure. In this case, it would be Frick Address 135 (decimal). Since this is the only address we are interested in obtaining the value of, send the following message: Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed Look at this message on a more basic level, to understand how the address that we are requesting is arrived at.

This represents a heads up alert that data is coming down the line. : CRLF } Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed : CRLF 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, all panels will look at the first byte following the Colon ( : ). If this byte equals the Panel ID # of the particular Quantum being queried, it will immediately finish reading the remainder of the message. If the byte does not equal its ID #, the message will be ignored. } Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed : CRLF In this particular example, we are strictly looking to request to view a data value, so we will be performing a read function (03): } Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed : CRLF 135 decimal equals 87 hex. Looking at our example, we see that we need a H.O. (High Order) address and a L.O. (Low Order) address. Since all data sent and received is in ASCII Hex Byte format, we need to look at 87 Hex as the Low Order portion of the address. The High Order portion is 00. Now our decimal 135 is formatted as 0087 Hex. } : CRLF Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed

34 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 34 Since we are only looking for this one address, and no other, we can say that we are only looking for one Data Address. Our Data Address part of the data packet is also looking for a High and a Low Order value. Fortunately, the number one (1) is the same in decimal as it is in Hex, therefore, the Low Order Address is 01 (hex). The High Order Address is 00 (hex), so our decimal 1 is formatted as 0001 (hex). Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed In order to ensure that the Quantum in question receives the data request accurately, we must append an Error Check byte to the end of the message. This is accomplished by adding each of the byte pairs (hex) that we have generated thus far: = 8C hex Next, subtract 8C (hex) from 100 (hex): Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed 100 (hex) - 8C (hex) = 74 (hex) After the entire data packet has been created, simply press the [Enter] key, a Line Feed will automatically be sent also. : CRLF Where: Start of Message Quantum ID # Read Function H.O. address (hex) L.O. address (hex) H.O. # of Data Registers L.O. # of Data Registers Error Correction Code Carriage Return Line Feed } : CRLF } : CRLF } Write Example: To demonstrate how an address within the Quantum may be written to, the following test can be performed using Windows HyperTerminal: As an example, a Modbus command will be created, and sent to set the Quantum to set the Suction Pressure Control Point 1 to PSIA. First, be aware that data sent to and received by the Quantum has one decimal place assumed. This means that to send the value of 100.0, you actually need to send Using the address tables found later in this manual, locate the address for the Suction Pressure Control Point 1. In this case, it would be Frick Address 277 (decimal). Since this is the only address we are interested in writing to, send the following message: : E8 F8 CRLF Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed Look at this message on a more basic level, to understand how the address that we are writing to is arrived at. We want to send the value of 1000 (100.0) to the Suction Pressure Control Point 1, Frick Address 277 (decimal). The first part of the message will be a Colon (:). This represents a heads up alert that data is coming down the line. } Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed : E8 F8 CRLF 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, all panels will look at the first byte following the Colon (:). If this byte equals the Panel ID # of the particular Quantum being queried, it will immediately finish reading the remainder of the message. If the byte does not equal its ID #, the message will be ignored.

35 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 35 In this particular example, we are strictly looking to write a data value, so we will be performing a write function (06): } Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed 277 decimal equals 115 hex. Looking at our example, we see that we need a H.O. (High Order) address and a L.O. (Low Order) address. Since all data sent and received is in ASCII Hex Byte format, we need to look at 15 Hex as the Low Order portion of the address. The High Order portion is 01. Now our decimal 277 is formatted as 0115 Hex. Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed : E8 F8 CRLF } : E8 F8 CRLF The value that we wish to send is (1000). Our Data Value part of the data packet is looking for a High and a Low Order value. The number 1000 (dec) must be converted to hexadecimal. This conversion results in 03E8 (hex). Separating 03E8 into two bytes results in the Low Order Value of E8 (hex) and the High Order Value of 03 (hex): } : E8 F8 CRLF In order to ensure that the Quantum in question receives the data request accurately, we must append an Error Check byte to the end of the message. This is accomplished by adding each of the byte pairs (hex) that we have generated thus far: E8 = 108 hex Normally, we would subtract 108 (hex) from 100 (hex), as in the previous read example. However, in this case we see that 108 hex is greater than 100 hex. Since the math in this particular example would yield a negative number (FFFFFFF8), we need to modify the value of 108 in order to provide a positive result. This is accomplished quite simply by dropping the most left hand digit (108 becomes 08), and then subtracting 8 hex from 100 hex: Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed 100 (hex) - 08 (hex) = F8 (hex) } : E8 F8 CRLF After the entire data packet has been created, simply press the [Enter] key, a Line Feed will automatically be sent also. : E8 F8 CRLF Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed } Where: Start of Message Quantum ID # Write Function H.O. address (hex) L.O. address (hex) H.O. # of Data Value L.O. # of Data Value Error Correction Code Carriage Return Line Feed

In the Query Response (read function) example used earlier, a response of : D025 (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 the Quantum to the Master this time, the Master will accept it. } Where: Start of Message Quantum ID # Read Function Number of Bytes Returned Data Error Correction Code : D0 25 After having received the Colon (:), the Master will look at the two bytes that follows it, so that it may determine from which Quantum the message is coming from. The next byte tells the Master how many bytes of information are being returned as a response. In this case, there are two (2) bytes of valid data. Where: Start of Message Quantum ID # Read Function Number of Bytes Returned Data Error Correction Code The next two bytes (in this case) are the actual data in response to our original request. Where: Start of Message Quantum ID # Read Function Number of Bytes Returned Data { : D0 25 : D0 25 Error Correction Code } Where: Start of Message Quantum ID # Read Function Number of Bytes Returned Data Error Correction Code : D0 25 Now that the Master knows which panel is responding, it needs to known which function the panel is responding to. In this case, it sees that it is a read function, and the Quantum is merely returning a value that was previously requested. Where: Start of Message Quantum ID # Read Function Number of Bytes Returned Data { : D0 25 We need to know what this value means. To break it down, we must convert the pair of bytes from Hex to Decimal: 05DO (hex) = 1488 (decimal) Data 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. From the previous paragraph, we can assume that there is one decimal place to be applied to the data value that was returned. Therefore: 1488 (decimal) = (decimal) All temperatures are in degrees C and all pressures are in PSIA unless the command is sent to select the units of the panel. Therefore: (decimal) = PSIA Error Correction Code

37 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 37 MODBUS NOTES: This has been an example of how the Quantum Controller uses the Modbus Protocol. It is hoped that the information provided here will assist the end user in writing applications that will allow the Quantum to be implemented into networks that the customer may already have in use. This information is subject to change at any time, and is provided as a reference only. Not all areas of the Modbus Protocol can be handled in this document. Some additional information regarding Modbus Protocol that the end user should be aware of: There are many versions of Modbus Protocol that is available, and an application that works properly on one system, may not function identically on another. Some versions of Modbus Protocol may require the user to increment any referenced addresses by 1 (one). For instance, if you wanted to look at Frick Address 135, you may need to actually look at address 136. The Quantum addressing begins at 0 (zero), whereas some Modbus Protocols begin at 1 (one), therefore, you may need to compensate. DO use Modbus ASCII. DO NOT use Modbus RTU. 7 or 8 Data bits may be used. 1 or 2 Stop bits may be used. Parity can be set to None, Odd or Even Follow the Frick specifications for data communications requirements. NOTE: Be careful not to continuously request a setpoint change. It is to be expected that communications may slow down during the process of writing setpoints or clearing alarms. Both of these processes involve writing to either EEPROM or Flash Memory and does take some time. If communication requests are being sent faster than once every couple of seconds, there will be temporary slowdowns during these processes.

38 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 38 YORK ISN DATA ACCESS ISN Revision 7 The Quantum panels Com-2 serial port is connected to a ISN s RS-485 serial port that is configured for York Talk communications. Wire the ISN s RX / -TX to the Quantum P12 pin 1 (-RX / -TX) and wire the ISN s +RX / +TX to the Quantum P12 pin 2 (+RX / +TX). Check that the ISN communication protocol has been selected from the Panel Setup Change Communications screen and that the baud rate of Com-2 and the panel ID number coincide with the setup of the ISN device. The Quantum ID number is used for the ISN Node number. The data exchanged with the ISN is found on pages (P) in feature (F) 54 of the ISN. All temperatures are in degree C and all pressures are in PSIA. 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 1 is sent if it is in automatic, or a 2 is sent if it is in remote. When changing a setpoint, the setpoint range is checked to see if the received value is an allowed setting. If it is not allowed, the setting is not changed. If the compressor is to be remotely controlled and the settings being sent from the ISN are not wanted to be used for control, then two digital bytes must be set to a one (1) to tell the Quantum to ignore the control settings being sent to it from the ISN. Sending a one (1) in the Start/Stop Enable digital byte from the ISN will signal the Quantum to ignore the Start/Stop digital value received from the ISN. Sending a one (1) in the Change Setpoints Enable digital byte from the ISN will signal the Quantum to ignore the setpoint values received from the ISN. If the compressor is to be remotely controlled from the ISN settings, then the compressor must be in remote to accept the start and stop commands that are sent through serial communication and the Start/Stop Enable received from the ISN must equal zero (0).

41 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 41 HYPERTERMINAL HyperTerminal is a terminal emulation program which resides in the MicroSoft Windows environment, and as such, will normally be found on any computer that is running Microsoft Windows. HyperTerminal provides a method by which the end user may verify conclusively that their Quantum controller is functioning properly, and as designed, with respect to external communications to remote devices. Many times, the Quantum controller will be installed into an environment whereby the end user wishes to communicate to it, either through a PLC (Programmable Logic Controller), a desktop computer for the purpose of monitoring/controlling plant operations through HMI (Human Machine Interface), or any number of other communications applications. The purpose of this desired communications typically involves viewing and changing setpoints, starting and stopping a compressor, viewing alarm and shutdown information, and viewing current operating conditions. When first connecting a Quantum panel to a communications network, it would be highly desirable to determine that all necessary parameters (jumper settings, panel setup, and cabling) are properly met so that communications may be established quickly with the Quantum, so that time is not lost in trying to troubleshoot a potentially simple problem. A modem or direct connection from a Comm port of a computer running Microsoft Windows can be used to connect to Com-2 of the Quantum. Setting up Hyperterminal You will need to locate either a lap top or desktop computer, that has Hyperterminal installed. Turn on the power for the lap top. After the laptop has fully booted, locate the Hyperterminal program. (Hyperterminal is usually found in the Accessories folder). If Hyperterminal can't be found there, try using the Find File command, and search the entire hard drive. Be aware that the screens that are actually shown on the test computer may or may not appear exactly as shown here. Various versions of Windows can affect the appearance, as well as whether or not the screen has been maximized, or if it has been scaled to a smaller size. Regardless of how the screen work appears, the function of the screen work is what is important, and that function is not affected by the way the screen looks. Once Hyperterminal has been located, execute it. A dialog box will appear. You will be prompted to enter a name for the New Connection. Type in whatever name you would like to use, Frick was used in this example. This name will also create a file once you are finished, saving all of the setup parameters for future use. It is recommended that a name be chosen to reflect the type of Protocol that you will be using as you may wish to setup for various protocols. Once you have entered a name, click [OK].

42 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 42 A new dialog box will be shown asking to select a Com port (choose the Com port that your communications cable is attached to, this will normally be Com-1). The phone number box should be blank. Click on [OK]. The Com-1 properties dialog box will now appear. The parameters in this box must match the requirements of the protocol that you are wishing to use. The one box that normally would need to be changed from one protocol to the next is the Data Bits box. For Modbus, you would want to use 7 data bits, for Frick and Quantum protocols, use 8 data bits. NOTE: Allen-Bradley protocol cannot be tested using Hyperterminal. For the purpose of this document, Frick # protocol will be used. Refer to the Modbus section of this manual for information on Modbus. Set the five boxes as follows, then click [OK]. Bits per second: 9600 (must match the Quantum ) Data bits: 8 Parity: None Stop Bits: 1 Flow Control: None

43 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 43 The following screen will appear. This is the screen whereby all communications (out of the computer, and into it) will be shown. When valid data is typed in here, then sent, the connected device recognizes and responds to that data, and a response will be shown below the sent data. Click on [File]. A pull down menu will appear. From this menu, locate and click on [Properties]. You will once again see the following screen. This time, click on the [Settings] tab.

44 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 44 The computer will need to be set up to match the documentation as presented here, for everything to look and work as shown later. To do this, click on the [ASCII Setup ] button. On the ASCII Setup screen, for best results, check the boxes 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, then click on [OK].

45 The Properties screen will once again be shown. Click on the [OK] button to proceed. FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 45 You will now be back to the main Hyperterminal communications screen. This screen will be blank. All communications, both from the computer, and to the computer (from the Quantum ), will appear on this screen. Proceed to the Testing Communications section.

46 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 46 Testing Communications Set the keyboard for CAPS (so that all capital letters will be typed). Type in the following command: #01I, then press [ENTER]. (This command will request the Quantum with ID 01 to send a packet of Information.) If the communications is working properly, there should be an immediate response from the first Quantum. The response should look something (but not necessarily exactly) like #01I000AOMN609. Go to the first Quantum in line, and check the Show Comms screen that was described earlier. You should see your message (and the Quantum reply) displayed there. If this portion of the test has passed, you can try to communicate to the next (or any Quantum, by changing the value that you type into the HyperTerminal screen as follows: Instead of [#01], replace the 01 portion with the ID that you would like to access. For instance, if you wanted to talk to a fourth Quantum (ID 4), type in [#04]. This should return a message from that Quantum. This has been just a brief description of how to check your communications and verify that it is working. Greater detail can be found by consulting tables for each of the protocols in this manual. General Notes: Ensure that the Quantum is set for the correct ID number, BAUD rate and type of communications protocol that is to be used. This setup can be found by pressing the [Menu] key on the keypad, then pressing the [Panel Setup] key that will appear at the right side of the display. When the panel setup appears, look at the information at the CHANGE COMMS line of the screen. This info must match the communications that you are trying to establish at the other end. There are two red LED s associated with the Com-2 port on the Quantum (TX2 & RX2). Ensure that neither of these LED s are on continuously. If one or the other (or both) are on constantly, disconnect the Com cable. If the status of the LED s does not change, check the wiring connections to the communications port. Ensure that the wiring is not backwards. If the wiring is correct, power the Quantum down, then back up. If either or both of the LED s is still on, a bad driver chip may be suspected on the Quantum, and the board should be replaced. Once everything has been inspected (cables, jumpers, and setup), try to develop communications from the master. You should see the LED s on the Com-2 port flickering as the Quantum talks to the master. If nothing happens, it would be best to consult the HyperTerminal section of this memo for more detailed troubleshooting. If you do see the LED s flickering, but data at the master device does not look correct, you can verify what is being sent and received at the Quantum by: Pressing the [Menu] key on the keypad, then when the Main Menu screen appears, find and press the [MORE ] button. A second Main Menu screen will appear. Find and press the [Service Screen] key

47 FRICK QUANTUM COMPRESSOR CONTROL PANEL S CS Page 47 The Service Screen will appear. Press the [Show Comms] key at the top right of the screen to view the communications information. You will now be viewing all of the communications information that Com-2 is receiving and transmitting. This screen will require you to update it manually be pressing the [Show Comms] key periodically. This screen will display all data that is coming through the Com ports. At the left of each line, you should see whether the 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 Hexadecimal format). 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 the communications data. If no data appears, or if the data does not match the specific protocol requirements that you are using, then one of the following things can be the problem: Quantum Panel Setup is wrong. Access the Panel Setup screen and verify that the Quantum ID is set to the same value that you are trying to access. Also, check that the baud rate matches that of the setup in the properties section of the Hyperterminal example. entitled Quantum 3 Communications Jumpers for the Quantum 3, or entitled Quantum 4 Communications 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 followed exactly. Repeat the process if necessary. If you are using a converter card (to convert the RS-232 signal from the computer to RS-422 or RS-485), then either verify that the converter card is working properly with a different piece of known functioning equipment, or eliminate it completely by tying into the Quantum directly through RS-232. The Communications port on the computer is bad. Try to verify this by communicating to a different piece of known good equipment. The Communications port on the Quantum is bad. Quantum jumpers. Verify the position of the jumpers by comparing them with the section

48 S CS FRICK QUANTUM COMPRESSOR CONTROL PANEL Page 48 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 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 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 Maintenance S M for the setpoints default settings and ranges. Reference the Quantum Data Table in this manual 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. Modbus Addressing Note: When using Modbus protocol (other than the Hyperterminal example shown earlier), it is necessary to use the Modbus Address as shown in the following tables. These addresses should work for most applications.

Note 2: The Compressor sequence De-Activate command that is sent through communications will only work if the Compressor sequence Activate command was last sent through communications. Note 3: A Capacity Control can only be made Active if it was enabled for capacity control and Setback is not Active and Input Module Capacity Control is not enabled. Note 4: A write message for more than one element is allowed for the Allen Bradley N55:0 address. A maximum size of 14 elements can be written to. An invalid setting sent with a Write Message is ignored. Note 5: Command Values need tenths field added. For example, to start the compressor, the table above states that 1 = Start. However, being that one decimal place is assumed, a value of 10 actually needs to be sent.

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. The maximum number of alarms that can be requested is 19. The message size value determines how many alarms are returned. 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 19 alarms is desired, set the message size to 57. Reference the numerical listing of the alarm codes in this manual. An alternate way to access the alarm data is to utilize Frick Addresses Each alarm is accessible independently. For instance, reading Frick Address 2602 will return the value of the most recent alarm code. This code value will correspond to the ALARMS/SHUTDOWNS MESSAGE CODE near the back of this manual. Reading the next address (2603) will return the hours integer (0 to 24) and the following address (2604) will give the minutes integer (0 to 59). It should be pointed out that an alarm value of zero indicates that although no alarm is present, there is a still a time stamp returned. Simply ignore this time stamp. The High and Low Order Date values sent with the Alarm information define a 32-bit number that describes the number of seconds that have passed since January 1, The High Order Date holds the upper 16-bits of this number, while the Low Order Date holds the lower 16-bits. To combine these values into one number, the High Order value must be multiplied by 2 16 or 65,536. The resulting value should then be added to the Low Order Value. We can use the following values as an example: Alarm # 1 Date High Order = 14423, and Alarm # 2 Date Low order = First, we multiply x 65,536 = 945,225,728. Then we add this value to and get 945,286,388. This value represents the number of seconds that have passed from January 1, 1970 to the time that Alarm # 1 occurred. A quick calculation will confirm that this number does describe a date in late 1999: 945,286,388 sec. * 60 sec. * 60 min. * 24 hr. = 10, days 10, days * 365 days = yr = indicates that the alarm occurred in 1999 and 97/100 s. If you take 97/100 * 365 yr. the answer would be (or just 354). This would equate to the 354 th day of 1999, or December 20 th, Of course, to use this value to define an exact date and time, more precise calculations must be used, including accounting for Leap years. We realize that this is a rather involved calculation which is why the Alarm s Hour and Minute values are provided. Only if Date and Time information is required beyond Hours or Minutes, should the Date High Order and Low order values be used. These addresses have been provided in order to assist the end user with their applications. Note 2: A read request to Frick Address 2501 return two values for the number of hours the machine has run. The first value is the number of hours greater than 1000 and the second value is the number of hours less than The size of the read message must be set to two to properly receive this data. An alternate way to access the Run Time Hours is to utilize Frick Address 2600 and Address 2600 now contains the hours greater than 1000, and address 2601 contains the hours less than As an example, if the Quantum Run Time hours displays 3,456 hours, this would break down as follows: Frick Address 2600 = 003 Frick Address 2601 = 456 If the Quantum Run Time hours displays 32 hours, this would break down as follows: Frick Address 2600 = 000 Frick Address 2601 = 032 These addresses have been provided in order to assist the end user with their applications.

73 FRICK QUANTUM COMPRESSOR CONTROL PANEL QUANTUM 3 MAIN BOARD HISTORY AND IDENTIFICATION The processor board shown on this page is known as the Quantum 3 and has been in production since January Frick Company developed this board as the successor to the Quantum 1 & 2 and it is based on the Pentium microprocessor platform. The Quantum 3 board can be identified by the presence of a piggy-backed daughter board mounted to the main board. This daughter board can be easily identified by the presence of a large black heat sink mounted on the main processor chip. There are also a number of jumpers (or links) present on this smaller board. It is NOT advised to modify these jumpers. The main board (communications board) has a 2-digit LED display (which during normal operation, will display a constantly changing pattern of values), an 8 position DIP switch pack on the main board, and a number of jumpers (or links). The links on this main board MAY need to be modified by factory qualified personnel to configure the Quantum for specific applications. Refer to the next page for more details on the settings of these Links. S CS Page 73 Unlike the Quantum 1 & 2, which utilized EPROMS for the Operating Software, the Quantum 3 utilizes Flash Card technology. There is a Flash Card socket located on this main board. The Operating System has been preloaded at the factory, so this Flash Card feature will primarily be utilized for future program updates. When calling Frick Company for service or help, it will greatly assist us if the type of board is known, either Quantum 1, 2, 3 or 4 (Quantum 1 & 2 is described in the Communications Manual S CS Version 3.5x/4.0 and previous versions). Additionally, Frick will request the Sales Order number, and the Operating System version number (this can be found on the Menu About screen). The more information you have at the time of the call, the better able we will be to assist you. The information that follows will primarily describe the jumper configuration for communications settings, as well as wiring diagrams for the different types of communications that are possible with the Quantum 3.
