1. IntroductionThe MACO 4000, 5000 and 6000 Series systems provide a host communicationoption using either an RS-232 or RS-485 host communication module to link thecontrol system to a host computer, allowing full Supervisory Control and DataAcquisition (SCADA) over a standard network platform. When fitted with a MACORS-485 host communication module, a MACO controlled machine can be at-tached to a network of up to 32 devices on a single serial port of a host computerCommunications can be used to collect, display and store operating data, as wellas transmit setpoints or change control relays in the MACO controllers.

1.1 Multi-Chassis AddressingEach controller of a multi-chassis system has its own set of control relay (CR)system addresses. The control relay addresses shown in this manual reflect theaddresses used for Controller 1 (the “primary” controller).

Almost all control relays repeat in a multi-chassis system. The few exceptionsrelate to recipes, some SPC items (data handler modfile), print CRs, switch LEDCRs (sequence modfile), status CRs from the display processor, data handler, RS-232 host communications, and RS-485 host communications modfiles. Refer tothe control relay tables for a complete list of control relays.

The control relay table contains a column headed “Multi-Chassis Addressing?”.Those control relays which have a “Yes” entry in that column can be written intothe RLD if a multi-chassis system is being utilized. With the exception of controlrelay addressing, multi-chassis operation is transparent to the RLD. All download-ing and recipe storage is to Controller 1. “Enabling” relays which relate to systemoperation (recipe saving and reading, setpoint change, etc.) must be enabled inEACH chassis. Machine function keys and RS-232/Printer/RS-485 functions areonly in Controller 1.

Note: When counting boards in multi-chassis systems (for switch settings, RLD/screen programming) count each control rack separately. For example, if a multi-chassis system consists of two control racks, each with two temperature boards,EACH controller would have a Temperature Board #1 and a Temperature Board#2. The same numbering scheme holds true for all types of boards (including Inputand Output boards).

Note: Currently the host communications can only communicate with Controller#1 (the primary chassis).

2. MACO Serial Communication SetupThe MACO serial communications setup screen (Figure 2.0) is used for settingbaud rates and enabling communications. This controller can have as many asthree separate external devices connected for use with serial communications.Daughterboards purchased for the communications motherboard determine whattype of device can be connected. The COMM numbers correspond to daughterboardlocations on the motherboard:

COMM 3 Upper SlotCOMM 2 Middle SlotCOMM 1 Bottom Slot

Examine the communications motherboard and determine the type and location

1640-IN-025-A-05 of 56



of whatever daughterboards are present (numbers are plainly marked on theboard). You may be using one or all of the communication modules listed below.

A-13405-00X RS-232 for communications(File Transfer and Host Communications)

A-13405-10X RS-232 for communications as well as printer functionsA-60055 (Screen Printouts and SPC Reports)

A-13404-20X RS-485 for communications to a hostA-60062

2.1 COMM SetpointsCOMM setpoints (Figure 1) allow the user to enable the communicationdaughterboards located in COMM slot 1, 2 or 3. To enable RS-232 hostcommunications enter a "1" in the correct COMM slot location. To enable an RS-232 printer enter a "2" in the correct COMM slot location. To enable RS-485 hostcommunications enter a "9" in the correct COMM slot location.

Note: Only ONE of EACH DEVICE is allowed (i.e., two RS-232 printers or two RS-232 PCs, etc. are not allowed).

2.2 Baud Rate SetpointsBaud rate is set by entering a baud rate setpoint on the serial communicationssetup screen. The baud rate must match that of the host. The serial communica-tions setup screen is pre-configured for RS-232. If the RS-485 communicationmodule is being used, an RS-485 baud rate setpoint can be added using theOptiGrafix™ screen editor. Enter a baud rate setpoint for each device:

0 = 9600 3 = 12001 = 4800 4 = 192002 = 2400

If the baud rate setpoint is not programmed on a screen it defaults to 9600 baud.

Figure 1. Serial Communications Setup Screen

1640-IN-025-A-05 of 56



2.3 Port Control Relay StatusThe port control relays listed at the bottom of the communication setup screenindicate the status of any ongoing communications. For an RS-232 device anasterisk will indicate the status of each line. The asterisk will indicate if data isbeing transmitted or received (these are not “real time” indicators - they are meantonly to show that communication is taking place).

3. RS-232 Host CommunicationsThe MACO RS-232 host communication module allows you to attach your MACOcontrolled machine to a single serial port of a host computer that will collect, displayand store operating data, as well as transmit setpoints to the MACO controllers.

3.1 Hardware RequirementsThe RS-232 host communication module (daughterboard) resides in one of theslots of the communication motherboard. There are no hardware jumpers orswitch settings used with the RS-232 host communication module. Simply mountthe host communication module to the motherboard.

The communications motherboard must be installed in Primary Chassis 1 in a slotwhich has a control data bus connector (the middle connector on the back-planeof the MACO controller).

3.2 Control RelaysBefore attempting to establish communications between the Host and the MACO,make certain to enable or disable the CRs appropriate for your application. If theCRs listed below are not set correctly, change them in the RLD logic using the RLDEditor software program.

3.2.1 Inhibit Remote Access (CR 649)Control relay 649 is used to inhibit remote access such as from a personalcomputer to the MACO controller. With this relay energized, the MACO controllerwill not accept any changes from a remote device.

3.2.2 Enable Remote Setpoint Change (CR 650)Control relay 650 is used to enable remote setpoint changes. This control relaymust be energized (and control relay 649 must be de-energized) in order to makesetpoint changes from a remote device.

3.2.3 Enable Remote CR Change (CR 651)Control relay 651 is used to enable remote control relay changes. This controlrelay must be energized (and control relay 649 must be de-energized) in order tomake control relay changes from a remote device.

3.3 WiringThe standard cables shown in Figure 3 are available in 10 to 50 foot lengths.

3.4 Establishing Data AcquisitionThe Host begins with:

<DLE><ENQ>

The MACO will respond (within 10 milliseconds) with:

<DLE<ACK><NUL> (if it is ready)or:<DLE<NAK><SOH> (if it is NOT ready) (retry at least three times before aborting)

The Host continues with:

<DLE><SOH><DLE><STX>

followed immediately by a Request Data Command or a Send Data Command.

3.5 Request Data CommandsA Request Data Command sent from the Host must consist of the following bytes:

<BC><ST><PB><AD><FN><TYU><TYL><CK>

where:

<BC> Byte Count (from <BC> thru <TYL>) (always 07H for a Request Data)

<ST> Status Byte (always 00H for Request Data)

<PB> Primary Control Byte (always 45H for a Request Data)

<AD> Function Address - Each controller of a multi-chassis system has its ownset of system addresses, where 1, 2, 3, and 4 identify the Controllerchassis in which the function board is located.

Controller #1 (Primary) 1XHController #2 2XHController #3 3XHController #4 4XH

The "X" indicates the board number of a function (i.e., the first tempera-ture board of a primary system would be 11H; the second board wouldbe 12H; the first board in the Controller #2 would be 21H).

Note: Currently the RS-232 can only communicate with the Controller #1chassis (primary).

<FN> Function Number - MACO functions are identified as follows:

01H Sequence02H Temperature03H Hydraulic04H Parison05H Accel/Decel30H RS-232 Communications38H RS-485 SPI Communications3AH RS-485 Host Communications40H Data Handler

1640-IN-025-A-05 of 56



<TYU> Type, Upper - The Type Upper Byte identification of specific Values,Setpoints, Control Relays or ASCII Strings found in the tables undertheir corresponding tabs of this manual. The first number of the MACOtypes are defined as follows:

0XH is a Value1XH is a Setpoint2XH is a Control Relay4XH is an ASCII String5XH is a Module Alterable Setpoint6XH Is a System Command

The Type Upper Byte corresponds to the two left-most digits of "ty"and is in hexadecimal. <TYU> together with <TYL> form the entry.

<TYL> Type, Lower - The Type Lower Byte completes the identification ofspecific Values, Setpoints, CRs or ASCII Strings (corresponds to thetwo right-most digits of "ty"). This entry is in hexadecimal. <TYU>together with <TYL> form the entry.

<CK> Checksum Byte - The bytes from <BC> through <TYL> are addedtogether and their 2's complement is taken. The sum of all the data plusthe checksum should be zero.

Note: Refer to examples to learn how to calculate a 2's complement.

3.6 Error Reply to Request Data CommandIf for some reason, the MACO does not understand the request (invalid functionaddress, invalid function number, etc.), it will respond as follows:

<UID><BC><ST><PB><01><EC><CK>

where:

<UID> Unit ID - Unit address of MACO system (always 01H for RS-232communications).

<BC> Byte Count (from <BC> through <EC>) (always 05H for an error replyto Request Data).

<ST> Status Byte (always XXH (don't care) for error reply).

<PB> Primary Control Byte (always 83H for error reply).

<EC> Error Code (see Error Code explanation).

<CK> Checksum Byte - The bytes from <UID> through <EC> are addedtogether and their 2's complement is taken. The sum of all the data plusthe checksum should be zero.

1640-IN-025-A-05 of 56



3.7 Reply to Valid Request Data CommandIf the data request is valid and received properly, the MACO responds as follows:

<UID><BC><ST><PB><DAT1><DAT2>...<DATX><CK>

where:


<BC> Byte Count (all bytes from <BC> through <DATX>).

<ST> Status Byte (always XXH (don't care) for a reply to Request Data).

<PB> Primary Control Byte (dependent on byte count - see 3.15 PrimaryControl Byte definition.

<DAT1> Data Byte 1.

<DAT2> Data Byte 2.

<DATX> Data Byte X.

The contents of the data bytes depend on whether the data requested is a setpoint,value, control relay or ASCII string:

Setpoints must be sent WITHOUT decimal points. Decimal placement is deter-mined by the column identified as "dec". For example, refer to the "Setpoint" tabof this manual and find the Cooling Output Limit (Section 2.23). A setpoint of 100.0is translated as "1000" (03E8H) and sent as (E8H)(03H), least significant byte first.

Note: In some setpoints and values the number of decimal places can be changedusing the OptiGrafix Screen Editor Program. The proper decimal place (dec) mustbe verified from the screens installed in the control system.

Setpoints<DAT1> is the Least Significant Byte<DAT2> is the Most Significant Byte

Unipolar Setpoints have a range from (0000H) to (FFFFH) or (0 to 65,535decimal). They are returned as unsigned (positive) numbers.

Bipolar Setpoints have a range from (8000H) to (7FFFH) or (-32,768 to 32,767).

If the Most Significant Bit of <DAT2> is set, the number is NEGATIVE.

Values<DAT1> is the Least Significant Byte.<DAT2> is the Most Significant Byte.

Unipolar Values have a range from (0000H) to (FFFFH) or (0 to 65,535 decimal).They are returned as unsigned (positive) numbers.

Bipolar Values have a range from (8000H) to (7FFFH) or (-32,768 to 32,767).

If the Most Significant Bit of <DAT2> is set, the number is NEGATIVE.

1640-IN-025-A-05 of 56



Control RelaysControl relays are read back in groups of 16.

<DAT1> Each of the 8 bits of <DAT1> represents the status of a single CR.

<DAT2> Each of the 8 bits of <DAT2> represents the status of a single CR.The group of 8 CRs represented in <DAT1> is determined by <TYL> of the RequestData Command.

The "X" digit of <TYU> completes the determination of a single CR. "X" can be anynumber from zero to seven and corresponds to the bit number in <DAT1>.

For example, suppose the operator wishes to read the Retune Zone 2 CR (ofTemperature). <TYU> and <TYL> of the request would be used to identify thatparticular control relay (2100H).

The MACO responds with the status of eight control relays (from 2000 to 2700)in <DAT1>.

2000 is bit 0 of <DAT1> (the LSB)2100 is bit 1 of <DAT1>2200 is bit 2 of <DAT1>2300 is bit 3 of <DAT1> 0=Off2400 is bit 4 of <DAT1> 1=On2500 is bit 5 of <DAT1>2600 is bit 6 of <DAT1>2700 is bit 7 of <DAT1> (the MSB)

<DAT2> will contain the status of eight more control relays (from 2001 to 2701).

2001 is bit 0 of <DAT2> (the LSB)2101 is bit 1 of <DAT2>2201 is bit 2 of <DAT2>2301 is bit 3 of <DAT2> 0=Off2401 is bit 4 of <DAT2> 1=On2501 is bit 5 of <DAT2>2601 is bit 6 of <DAT2>2701 is bit 7 of <DAT2> (the MSB)

<DAT2> is determined by <TYL> plus 1. (If <DAT1> represents the last eightcontrol relays of a function, then <DAT2> will be set to zero.

Selector Switches are a special case of control relays. Each nibble of the two databytes represents the status of a selector switch.

20XX is bit 0 of <DAT1 or 2> Pos. 1 (the LSB)21XX is bit 1 of <DAT1 or 2> Pos. 222XX is bit 2 of <DAT1 or 2> Pos. 323XX is bit 3 of <DAT1 or 2> Pos. 424XX is bit 4 of <DAT1 or 2> Pos. 125XX is bit 5 of <DAT1 or 2> Pos. 226XX is bit 6 of <DAT1 or 2> Pos. 327XX is bit 7 of <DAT1 or 2> (the MSB) Pos. 4

If the entire nibble is set to zero (all 4 bits), the selector switch is in Position Zero(turned OFF).

1640-IN-025-A-05 of 56



ASCII StringsASCII strings are used by the MACO to display titles, counter values, hour metervalues, etc.

MACO ASCII strings can be a maximum of 29 characters in length. See theMessage File and System Command tab section in this manual.

3.8 Send Data CommandsA Send Data Command to the MACO consists of the following bytes:

<BC><ST><PB><AD><FN><TYU><TYL><DAT1><DAT2><CK>

where:

<BC> Byte Count. The number of bytes sent from the Host (from <BC>through <DAT2> inclusive).

<ST> Status Byte (always 00H for a Send Data).

<PB> Primary Control Byte (<BC> minus 2 for a Send Data).

<AD> Function Address - Each controller of a multi-chassis system has itsown set of system addresses, where 1, 2, 3, and 4 identify thecontroller chassis in which the function board is located.


The "X" indicates the board number of a function (i.e., the first tempera-ture board of a primary system would be 11H; the second board wouldbe 12H; the first board in the Controller #2 would be 21H).

Note: Currently the RS-232 can only communicate with the Controller #1 chassis (Primary).

<FN> Function Number. MACO functions are identified as follows:


<TYU> Type, Upper - The Type Upper Byte identification of specific Values,Setpoints, Control Relays or ASCII Strings (corresponds to the tworight-most digits of "ty"), found in the tables under the correspondingtabs of this manual. The first number of the MACO types is defined asfollows:

1XH is a Setpoint2XH is a Control Relay

1640-IN-025-A-05 of 56



5XH Is a Module Alterable Setpoint6XH is a System Command

<TYL> Type, Lower - The Type Lower Byte completes the identification ofspecific Setpoints, Control Relays or System Commands (correspondsto the two right-most digits of "ty"). This entry is in hexadecimal formatfor host communications. <TYU> together with <TYL> form "ty."

<DAT1> Data Byte 1<DAT2> Data Byte 2

The contents of the data bytes depend on whether the data sent is a setpoint orcontrol relay.

Setpoints must be sent WITHOUT decimal points. Decimal placement is deter-mined by the column identified as "dec". For example, refer to the "Setpoint" tabof this manual and find the Cooling Output Limit (Section 2.23). A setpoint of 100.0is translated as "1000" (03E8H) and sent as (E8H)(03H), least significant byte first.

Ninety-nine point nine would be translated as "999" (03E7H) and sent as (E7H)(03H).

Note: In some setpoints and values the number of decimal places can be changedusing the OptiGrafix Screen Editor Program. The proper decimal place (dec) mustbe verified from the screens installed in the control system.

Setpoints<DAT1> is the Least Significant Byte<DAT2> is the Most Significant Byte

Unipolar Setpoints range from (0000H) to (FFFFH) or (0 to 65,535 decimal). Theyare sent as unsigned (positive) numbers.

Bipolar Setpoints range from (8000H) to (7FFFH) or (-32,768 to 32,767). Con-vert the decimal number to a 16-bit 2's complement binary equivalent.

Control RelaysNote that it is STRONGLY recommended NOT to use digital communications tochange the state of any Control Relay which may effect machine performance.

Use extreme caution when changing ANY control relay from a Host computer. Inmay applications, it is desirable to only enable the write CR's when the machineis in the idle state.

CR Send Data Commands are sent from the Host using a single data byte.

Only Operator control relays, Setup control relays, and Selector Switches can bechanged through digital communications.

Operator Control Relays (1657 - 1752) can be turned off (by sending a zero); canbe turned on (by sending a one); or can be toggled (by sending a two).

Momentary CRs (1753-1784 & 1913-1944) are NEVER to be energized usingdigital communications. If the momentary CRs are energized from the host they willturn ON and stay ON until turned OFF by an operator at the display.

Setup CRs (1785-1848) can be turned off (by sending a zero); can be turned on(by sending a one); or can be toggled (by sending a two).

1640-IN-025-A-05 of 56



Selector Switches (1849-1912) can be turned off (by sending a zero); can be setto Position 1 (by sending a one); can be set to Position 2 (by sending a two); canbe set to Position 3 (by sending a three); or can be set to Position 4 (by sendinga four).

System CommandsSystem Commands are sent from the Host without the use of a data byte. All thatis necessary in order to invoke a system command is to send the proper<TYU><TYL> bytes. See System Commands.

<CK> Checksum Byte - The bytes from <BC> through <DAT1 or 2> (<TYL>in the case of system commands) are added together and their 2'scomplement is taken. The sum of all the data plus the checksum shouldbe zero.

3.9 MACO Error Reply to Send Data CommandIf for some reason, the MACO does not understand the command (invalid functionaddress, invalid function number, corrupt data, etc.), it will respond as follows:

<UID><BC><ST><PB><01><EC><CK>

where:


<BC> Byte Count (from <BC> through <EC>) (always 05H for an error replyto Send Data Command).

<ST> Status Byte (always XXH (don't care) for error reply).

<PB> Primary Control Byte (always 83H for error reply).

<EC> Error Code (see Error Code explanation).

<CK> Checksum Byte - The bytes from <UID> through <EC> are addedtogether and their 2's complement is taken. The sum of all the data plusthe checksum should be zero.

3.10 Reply to Valid Send Data CommandIf the data sent is valid and is received properly, the MACO will respond as follows:

<UID><BC><ST><01><CK>

where:


<BC> Byte Count (from <BC> through <01>) (always 03H for a valid reply toSend Data.

<ST> Status Byte (always XXH (don't care) for a valid reply to a Send DataCommand).

1640-IN-025-A-05 of 56



<CK> Checksum Byte - The bytes from <UID> through <01> are addedtogether and their 2's complement is taken. The sum of all the data plusthe checksum should be zero.

3.11 Changing to the File Transfer ModeTo change from the Data Acquisition Mode to the File Transfer Mode, the Hostmust send ten sets of <DLE><EOT> characters.

To change from the File Transfer Mode to the Data Acquisition Mode, follow theprocedure for establishing the command mode.

3.12 Insertion of <DLE>If for any reason, a Request Data string or a Send Data string contains a <DLE>character (10H), an additional <DLE> character must be sent.

The byte count will be unaffected.

Only one of the <DLE>'s will be used in the checksum.

3.13 Determining Error Code DefinitionsThere are only two errors that relate directly to a problem with the RS-232communications. They are:

81H File Checksum Error

8DH File Data Handler Communications Error

If a Checksum Error (81H) occurs, retry at least three times before resetting oraborting communications.

A Data Handler Communications Error (8DH) is fatal.

Any other error codes relate to problems within the MACO. To determine themeaning of whatever error code appears, convert the two bytes following <PB>(83H) to decimal and locate the resulting number in the printout of the MessageFile. For example, if a checksum error occurred, the MACO would respond with:

<UID><BC><ST><PB><01><EC><CK>or:

<01H><05H><00H><83H><01H><81H><CK>

The two bytes following <PB> are <01H><81H>. 181hex equals 385 decimal.Message Number 385 is "File Checksum Error."

4. RS-485 Host CommunicationsThe MACO RS-485 Host communications module provides the capability to linkyour MACO 4000, 5000 and 6000 series control systems to a host computer. Thisallows full Supervisory Control and Data Acquisition (SCADA) over a standardnetwork platform. A single serial port on a computer can communicate with up to32 MACO controlled machines on a single cable. The host computer can collect,display and store operating data, as well as transmit setpoints and change controlrelay states to the MACO controllers.

Data can be read or written to MACO in blocks or as individual values or setpoints.Up to ten blocks can be defined. Each block can have as many as 60 values and/or setpoints. The module scans the menu of data items requested by the hostcomputer, starting with block “0” and proceeds until it encounters a blank block.There can be no blank fields within a block so be sure to construct a contiguousmenu when setting up your data acquisition routine at the host computer.

The buffer holds up to five blocks of data. The BUFFER MODE setpointdetermines the number of blocks to be gathered on a zero to 1 transition of theTRIGGER CR. If the BUFFER MODE setpoint = 0, the module collects datacontinuously. If the BUFFER MODE setpoint = 1, 2, 3, 4 or 5, data collection startswhen the TRIGGER CR goes high. The trigger does not have to be held high forthe entire gathering cycle. The DATA VALID CR (3765) is set when the specifiednumber of blocks has been collected and transferred to the output buffer.(Additional blocks, if requested, are gathered continuously).

4.1 Hardware RequirementsThere are two hardware jumpers and a bank o f 8 switches that must be manuallyset before installing the RS-485 host communications module (daughterboard)onto the communications motherboard.

Jumpers J1 and J2 are used to terminate the RS-485 data lines of your network.If you have three machines equipped with MACO's, the node located farthest fromhost would have the jumpers in the "IN" position and the other nodes would havethe jumpers in the "OUT" position.

The first 6 (1 - 6) switches of S1 are used to establish a node address for the card.Switches 7 and 8 determine some data transfer parameters (see next page).

The RS-485 host communication module can be used with Data Handler V20.76or newer and Sequence V03.46 or newer.

4.1.1 Editor RequirementsThe following versions of screen and RLD editors are required:

OptiGrafix V3.04 or newerRLD V4.5 or newer

Note: If all the switches (1-6) are in the ON position or a node address is greaterthan 32, the host communications module address will default to "0" and commu-nications will be disabled.

4.1.2.2 Switch 7 Save ConfigurationSwitch 7 ON: With switch 7 in the "ON" position, the table of parameters is savedin EEROM (on the RS-485 card). If the controller resets or powers down/powersup, the table will be read from the RS-485 card and does not need to be resent fromthe computer.

Switch 7 OFF: With switch 7 in the "OFF" position, the table of parameters is not

saved on the RS-485 card. If the controller resets or powers down/ powers up, thetable will have to be resent from the host.

4.1.2.3 Switch 8 Data UpdateWhen new data blocks are loaded, all setpoints and then all values are updatedduring the first pass through the new data. A block of data will not be sent to thehost until all setpoints and values have been updated (an error code of <NAK><46H>is sent until the data is ready).

Switch 8 ON: With switch 8 in the "ON" position, after the first update, values andsetpoints are updated at a ratio of 8 to 1 (values to setpoints, respectively).

Switch 8 OFF: With switch 8 in the "OFF" position, all setpoints and then all valuesare continuously updated.

4.1.3 Communication Board LocationThe RS-485 host communications module (daughterboard) mounts into anyposition on the communications motherboard.

The communications motherboard must be installed in a slot which has a controldata bus connector (the middle connector on the back-plane of the MACO controller.

4.2 General Setup ProcedureThe setup procedure consists of: setting the module node address (UID); installingthe MACO RS-485 host communications module; wiring each module to the hostcomputer; enabling the data handler (COMM SETPOINT = 9); and selecting abaud rate compatible with the host computer.

4.2.1 Control RelaysBefore attempting to establish communication between the host and MACO, makecertain the following CRs are properly set in the RLD.

The following control relays should be energized as required:

CR 650 Enable Remote Setpoint ChangeCR 651 Enable Remote Control Relay ChangeCR 652 Enable Other Remote Functions (needed for Command #15)CR 653 Enable Remote Recipe SaveCR 654 Enable Remote Recipe ReadCR 655 Enable Remote Recipe Delete

CR 642 Inhibit Local Setpoint Change

4.3 WiringThe RS-485 module uses a four pin connector to communicate with the host.Connector E23-1134-004 is provided with screw terminals for field wiring.

The RS-485 cabling must run on the low voltage side of the MACO controller'scable tray located at the bottom of each chassis.

4.4 Module Setpoints

4.4.1 Baud Rate SetpointThe MACO RS-485 host communications module baud rate can be set by placingthe baud rate setpoint on a user screen using the OptiGrafix screen editor. Baudrate setpoints available are listed below;

0 = 9600 3 = 12001 = 4800 4 = 192002 = 2400

If the baud rate setpoint is not programmed on a screen, it defaults to 9600 baud.

4.4.2 COMMODE SetpointThis setpoint determines the mode of operation for monitoring data (triggered orcontinuous). The user must to add the COMMODE setpoint to a user screen inorder to allow access to this setpoint. The COMMODE setpoint listing is found inthe "Setpoint" section of this manual, Section 6.2. If the COMMODE setpoint is setto "0," monitored data is scanned continuously. If the COMMODE setpoint is notset to "0," the data gathering is in the triggered mode. The number of blocks (1 to5) are scanned when the TRIGGER control relay is energized.

Note: Only value parameters are triggered. Setpoints are monitored continuously.

4.4.3 Clear Data Valid TimerThis setpoint is used to enter the time delay after which the Data Valid ControlRelay (CR 3765) will be cleared by the module after it goes high. Valid only if theHost Control Relay (CR 3743) is low (logic 0). If the Host Control Relay (CR 3743)is high (logic 1), the module does not clear the Data Valid Timer (instead it wouldbe cleared by the Host using Command #7). Setpoint range is 3 to 20 seconds.If the setpoint is not included on any screen, it will default to 3 seconds.

4.5 Module Values

4.5.1 Block Value 1 - Block Value 10These values are used to display the number of parameters (setpoints plus values)in a specific data block. Note that early modfile versions may show these asReserved Value 2 - Reserved Value 11, respectively).

4.5.2 Number of SetpointsThis value is used to display the total number of setpoints in all of the data blocks(formerly labeled "reserved value 12").

1640-IN-025-A-05 of 56



4.5.3 Number of ValuesThis value is used to display the total number of values in all of the data blocks(formerly labeled "reserved value 13").

4.5.4 Switch ValueThis value is used to display the settings of switch 1 (formerly labeled "reservedvalue 16").

4.6 Module Control RelaysThe RS-485 Host communications module has three control relays that can beaddressed by the Relay Ladder Diagram (RLD). They are TRIGGER (CR #3753),HOST CONTROL (CR #3754) and DATA VALID (CR #3765).

The HOST CONTROL relay should be set high in the RLD if the host will be usedto clear the DATA VALID CR. After the host has read the last block, the DATAVALID control relay will be cleared when the host sends the COMMAND #7"CLEAR DATA VALID COMMAND". If the HOST CONTROL relay is not set high,the DATA VALID control relay will be cleared by the module 3 to 20 seconds afterit is set.

4.6.1 TRIGGER Control Relay (CR 3753)This is a "Sequence to Module" (STM) control relay which initiates gathering oftriggered monitor data when it is energized by logic (1). Recommend holding highfor at least two line cycles. The CR does not have to be held high while data is beinggathered. The CR must be de-energized (logic 0) after the DATA VALID controlrelay is energized (logic 1) and then re-energized (logic 1) to initiate the next cycle.

4.6.2 HOST Control Relay (CR 3754)This is a "Sequence to Module" (STM) control relay. When de-energized (logic 0),it causes the module to clear the DATA VALID according to the Clear Data ValidTimer setting (3 to 20 seconds). See Section 4.4.3.

Note: DATA VALID can still be cleared by the host.

If energized (logic 1), DATA VALID is cleared by the host using command #7.

4.6.3 DATA VALID Control Relay (CR 3765)this is a "Module to Sequence" (MTS) control relay. When the COMMODE setpointis zero (the non-triggered mode) CR 3765 is set high when data gathering.

When the COMMODE setpoint is 1-5 (the triggered mode), CR 3765 is set highwhen all data has been collected. It is cleared according to status of the HOSTCONTROL relay.

4.7 Module Error CodesThe RS-485 Host communication module will return one or more of the followingerror codes if it detects a communication error:

31H LRC checksum error32H Invalid number of parameters34H Invalid command parameters35H Setpoint limit error3AH Data command error3BH Time-slot running and remote access control relay not enabled3FH Invalid host command40H Time-out waiting for data handler44H Triggered Data Block Request and Data Valid not set.

4.7.1 Data Handler Error Code MessagesThe RS-485 host communication module will return one or more of the DataHandler Error Code Messages (0100H to 01FFH) listed in the System MessageDefinitions section (1640-IN-051-0-xx) of this manual.

The RS-485 host communication module removes the first byte of the two bytecode and transmits messages using the last byte (00H to FFH).

4.8 Command StructureCommands and responses are transmitted between the host computer and theRS-485 Host communications module in code bytes (< >). Commands areinitiated at the host and the RS-485 Host communications module responds.Unique code bytes are defined in the following paragraphs corresponding to thecommand in which they are used. Common code bytes include:

Mnemonic Definition

<AD> Function AddressEach controller of a multi-chassis system has its own set ofsystem addresses where 1, 2, 3, and 4 identify the chassisin which the function board is located.


The "X" identifies the board number of a function (i.e., the firsttemperature board of a primary system would be 11H; thesecond board would be 12H).

5.12 Command #14 – Request Host Monitor Error TableThe purpose of this command is to request the host monitor error table.

Command format from the host computer:<EOT><UID><UID><CC><CC><ETX><LRC>

where:

<EOT> Start of transmission (04H)<UID><UID> Node address of MACO controlled machine<CC><CC> Command code<ETX> End of text (03H)<LRC> Longitudinal redundancy check

Response from the module:<STX><UID><UID><128 bytes of daata><ETX><LRC> if successful, or<NAK><Error code> if not successful.

5.12.1 Example Command #14This is an example of a request host monitor error table.

Command format from the host computer:<EOT><UID><UID><CC><CC><ETX><LRC><04H><30H><31H><31H><34H><03H><03H>


<STX><UID><UID><128 bytes of data><ETX><LRC>

Data format:Each error consists of 8 bytes:<Block number byte><Parameter number byte>< ID (4 bytes)><Error code (2 bytes)>

The Block number is the number of the block (0-9, downloaded from the host) that
