2-2.5. DIOB Interface (SW1)

The QLC incorporates a standard DIOB interface. A single card-edge conne(P1) is used to connect the QLC to the Q-Crate backplane, providing the QLCinterface to the DIOB, as well as 13V DC power.

The QLC contains 2,048 words of dual port static RAM which is dedicated to Dcommunications. This static RAM maps to the QLC CPU memory (through oport) and to the DIOB interface (through the other port).

Two versions (or “groups”) of the QLC card are available. The Group 1 (G01) Qallows access to any of the 2,048 locations within the dedicated RAM, using speDPU algorithms. The Group 2 (G02) QLC can be programmed to emulate thDIOB interface of various Q-Line I/O cards. Depending on the configuration ofGroup 2 QLC, access is allowed to the first 8 or 16 words of the dedicated RA

2-2.6. Processors

The QLC is based on an 80C186 Central Processing Unit (CPU). The 80C186the same base architecture as the 8088 CPU used in IBM-PCs, and is complobject-code compatible with the 8088. However, the following differences shobe noted:

• The 80C186 has an external 16-bit data bus, where the 8088 has an 8-bitbus.

• The 80C186 incorporates a number of peripheral functions (which are locon peripheral ICs for the 8088).

• The 8088 BIOS does not support Flash Memory.

For these reasons, the IBM-PC BIOS was modified for use with the 80C186.

2-2.7. Memory

The QLC incorporates memory used for various purposes:

• 64 Kbytes EPROM containing the modified BIOS.

• 1 Mbyte DRAM including a 360-Kbyte RAM disk.

• 384 Kbytes CMOS flash (non-volatile) memory used to back up the RAM d

• 2 K X 16 dual port static RAM for DPU communications.


2-3. QLC Switch and Jumper Settings

The following switch and jumper settings should be verified prior to initializatiof the QLC:

• DIOB address DIP switch (SW1) (Section 2-3.1).

• Configuration DIP switch (SW3) (Section 2-3.2).

• DIOB Address Range jumpers (JS10 and JS16) for Group 2 QLC only(Section 2-3.3).

2-3.1. DIOB address DIP switch (SW1)

SW1 is a 7-position DIP switch (shown inFigure2-2) used to set the QLC’s DIOBaddress. Its use is equivalent to the DIOB address jumpers used on most Q-LO cards, as described in “Q-Line InstallationManual”(M0-0053). The DIP switchis provided because the QLC does not use the card-edge or half-shell terminconnectors (which contain the address jumpers).

Each DIOB address is a hexadecimal number in the range 08 through FB. Theaddresses depend on which group of the QLC is in use:

• The Group 1 QLC card uses two consecutive DIOB addresses. The first (“base”) address must end with an even hexadecimal digit (x0H, x2H, x4H, xxAH, xCH, or xEH, where x = any hexadecimal digit). For example, addres52H-53H could be assigned to the QLC G01 but 53H-54H could not.

• The Group 2 QLC card uses 8 or 16 consecutive DIOB addresses dependinthe settings of jumpers JS10 and JS16 (described inSection 2-3.3). When 8addresses are assigned to the QLC, the base address must end with ahexadecimal 0 or 8. When 16 addresses are assigned to the QLC, the baaddress must end with a hexadecimal 0.

Note

Do not use addresses 0 through 6 for Q-Line cards.



ed).

To set the DIOB address switches, determine the binary equivalent of thehexadecimal base address (seeTable 2-1).

Because the base address is always an even hexadecimal number, the leastsignificant bit (bit 0) will always equal 0 (no switch setting is required). Theremaining bits (bits 1-7) determine the SW1 switch settings (0 = open, 1 = clos

Example

The binary equivalents for hexadecimal values52H and53H are shown below:

For each bit that equals 1, the corresponding switch is closed. For each bit thequals 0, the corresponding switch is open. The switch settings for base add52H are illustrated inFigure 2-3.

Note

For a Group 2 QLC which uses 8 addresses, SW1switches 1 and 2 will always be open. For a Group 2QLC which uses 16 addresses, SW1 switches 1, 2,and 3 will always be open.

When assigning the QLC address, verify that the selected address will not conwith addresses required by or assigned to other Q-Line cards. For additionalinformation on Q-Line addressing, see “Q-Line Installation Manual” (M0-0053).

The external personal computer (used for initialization of the QLC) may be anIBM-PC, PC-XT, PC-AT, PS/2, or personal computer which is 100% compatibwith the DOS operating system (version 3.1, 3.2, 3.3, 5.0). At a minimum, thexternal personal computer must be equipped with a floppy disk drive (5-1/4 3-1/2 inch) and COM1 port.

Note

It is recommended that the external personalcomputer use the same version of PC-DOS that isloaded into the QLC.

The QLC card’s serial port (J2) is connected to the external personal computserial port (COM1 or COM2) using one of the following cables:

• Westinghouse Part Number 406A166 (to connect the QLC serial port 9-pin mD connector to a25-pin male D connector at the external personal computer)

• Westinghouse Part Number 406A167 (to connect the QLC serial port 9-pin mD connector to a9-pin male D connector at the external personal computer).

Both of these cables are available in several lengths, identified by group numbeshown inTable 2-3). For example, part number 406A166G03 identifies a 4-focable used to connect the QLC serial port to a 25-pin personal computer serial

2-6. QLC Software

As noted previously, the QLC BIOS is provided on EPROM. To operate the QLthe user must load PC-DOS (version 3.1, 3.2, 3.3, or 5.0) to the QLC’s RAM diOnce the RAM disk is loaded, it should be saved to flash (non-volatile) memo

Note

PC-DOS is recommended for use on the QLC. If anyother version of DOS is used, the user is responsiblefor ensuring that it is 100% compatible with PC-DOS.

The following programs are provided for use on the external personal compu

• EXTPC allows the QLC to receive commands from the external personalcomputer keyboard, and to write information to the external personal compCRT. This program must be used initially to load DOS (and files) to the Q

• BAKFLASH backs up the QLC’s RAM disk to flash (non-volatile) memory.

Note

The QLC’s RAM disk must be copied to flashmemory prior to resetting the card, rebooting, orcycling power. Otherwise, all data will be lost andthe QLC must be re-initialized.

Software installation is described inSection 3.




This section describes the initialization of the QLC card.

Section 3-2 provides step-by-step procedures for initializing the QLC card.

The QLC must be initialized from an external personal computer, which is useformat the QLC RAM disk, load DOS, and copy any other desired files to the RAdisk. To perform the initial programming (or any later action requiring keyboaCRT I/O), a serial port on the QLC is linked to the external personal computeCOM1 or COM2 port. In this configuration, code generated on the external perscomputer can be loaded into the QLC (seeFigure3-1). Once the QLC is initialized,the external personal computer can be removed, and the QLC operates as aalone IBM-compatible microcomputer.

Note

After initialization, the RAM must be backed up tonon-volatile memory.

Two programs are provided for use in QLC initialization. EXTPC is used to linthe QLC to the external personal computer. BAKFLASH is used to copy the RAdisk to flash memory.

3-2.1. Procedure

It is recommended that all QLC file operations be performed from a floppy disUse the following procedure to accomplish this.

Note

The QLC card is designed to be compatible with anyversion of DOS. Versions 3.1 through 5.0 have beentested successfully with this procedure.

To initialize the QLC, use the following steps:

1. Determine the default disk drive on the external personal computer, to befor QLC communication.

Note

While communicating with the QLC, only one diskdrive on the personal computer will be accessible.All desired files must be on that drive.

2. Place diskPQL1xx (where xx = revision level) into the desired drive, or copfilesEXTPC.EXE andBAKFLASH.EXE to the desired drive. Verify that theselected drive is a system (DOS) disk.

3. Place the QLC in an available Q-Crate slot.

Note

If using default naming in the DPU application, referto “Q-Line Installation Manual” (M0-0053) forinformation on slot and address usage.

4. Connect the cable from the QLC (J2 connector) to the personal computer(COM1 or COM2). (SeeSection2 for additional information on the cable to beused.)

5. Confirm that the proper cable is connected between the QLC’s serial portthe PC’s serial port (described inSection 2).

6. Format a floppy disk as a DOS bootable floppy by doing the following:

Place the disk into a floppy drive at the PC and type the following comman(assuming the disk is in driveA: ):

C:\>FORMAT A: /S

7. Copy the following programs and files to the floppy disk:

— FORMAT.COM program

— BAKFLASH.EXE program

— EXTPC.EXE program

— Any applicable QLC executable programs

— AUTOEXEC.BAT file (required for automatic startup of the QLCapplication)

— Any applicable configuration files

8. Set the following SW3 switches on the QLC card to communicate with theexternal PC and to boot from the external disk:

• Set switch 3off and switch 4on for 9600 baud.

• Set switch 3off and switch 4off for 19200 baud.

• Set switch 6on to enable the QLC to boot from the external disk.

9. Place the formatted floppy into the disk drive, and set that floppy drive as thdefault disk by typing the following command (assuming the disk is in driveA: ):

C:\>A:

10. Run EXTPC using the command line syntax shown below (refer toTable 3-1for drive identifiers):

EXTPC [port] [baud]

where:

port = COM1 or COM2 (default = COM1)

baud = 1200, 2400, 9600, or 19200 (default = 9600)

For example, the following command line specifies that the QLC is linked COM1 and that the baud rate is 2400:

A:\>EXTPC COM1 2400

If the port and baud rate are not specified, the default values will apply(port = COM1, baud = 9600).

11. Press theReset button on the QLC card. This will cause the QLC to initializitself and then to load DOS from the floppy disk.

After DOS is loaded, the following will occur:

• The screen on the PC will display theA:\> prompt.

• DOS is executing on the QLC card.

• The external floppy disk is known asA: .

• The internal disk on the QLC card is known asB: .

13. If the QLC card has not been initialized, format theB: disk as a system disk byentering the following command:

A:\>FORMAT B: /S

14. Copy any programs and files necessary for the operation of the QLC applicato the QLC disk (B:). These may include the following:

— Any applicable QLC executable programs.

— BAKFLASH.EXE program (if desired, and if there is sufficient space on tQLC’s internal disk B:).

— Any applicable configuration files.

— AUTOEXEC.BAT file (typically required in a QLC application). Do notplace this file on the QLC card until the application has been tested.

15. Enter the following command to save the current configuration of the QLCinternal disk:

A:\>BAKFLASH

Caution

It is extremely important to run the BAKFLASHprogram at this time. If this is not done, then thedata on the QLC internal disk will be lost.

16. At this time, set switch 6 of SW3 on the QLC card to theoff position.

This tells the QLC to read DOS from the internal disk. Reboot the QLC.

18. To exit the EXTPC program at the external personal computer, pressControl-Break .

For general information on the recommended QLC programming approach, asas application notes which may be helpful in programming the QLC, refer toSection 4. For additional information on IBM-PC programming, refer to theapplicable IBM and DOS documentation.

3-2.2. Drive Identifiers

Refer toTable 3-1 to determine the applicable drive identifiers for the QLC RAdisk and the default disk on the external personal computer.

Caution

Depending on the external drive selected, the driveidentifier may be changed during EXTPC use.

For example, if EXTPC is run from the floppydrive normally identified as B:, the drive will beidentified as A: during EXTPC use.

To avoid confusion, run EXTPC from drive A: ordrive C:.

Section 4. QLC Programming andOperation


Due to the QLC’s open design and the variety of possible applications,programming of the QLC is highly application dependent. However, in order design an effective QLC application, the user must be aware of how the QLCcommunicates through the DIOB. The DIOB interface is different for the twoversions of the QLC (Group 1 and Group 2). For this reason, the recommendprogramming approach depends on the QLC group.

This section provides the following information:

• Programming approaches for Group 1 and Group 2 QLCs (Section 4-2).

• General application notes (Section 4-3).

Appendix B provides examples of QLC application programs written in Clanguage, as well as sample DPU application entries.

In a typical QLC application, information is sent from a field device to the QLCSBX port to be transferred to the DPU. Data or commands from the DPU maybe obtained by the QLC and transmitted to the field device.

To implement a QLC application, the following general steps are required:

• Define the format of the data to be received (or transmitted) through the SC(SBX) serial port.

• Create a QLC application program to convert the data to an appropriate forand place it in DIOB-accessible RAM (or read data placed in RAM by the DIO

• Create the DPU application program to place the DIOB information into WDprocess points (or write point data to the DIOB).

Figure 4-1 illustrates the information flow between a field device and a DPU, usthe QLC interface. In this example, data is transmitted to the QLC from a field devin RS-232 format. This data is made available to the DPU through the DIOB.

When using the Group 1 QLC, the entire range of dual port RAM addresses(A0000H - A3FFFH) are available to the DIOB. Special DPU control algorithmreference this memory as holding registers or buffers.

When planning and implementing a Group 1 QLC application, the followingreference documents should be available:

• For detailed descriptions of the QLC algorithms, see“Control Algorithms”(U0-0106).

• For information on WDPF point record types and fields, see “Record TypesUser’s Guide” (U0-0131).

4-2.2. Application Programming for the Group 2 QLC

The Group 2 QLC is designed to operate with older DPUs (which do not suppthe special QLC algorithms) by emulating Q-Line input and output cards.

When using the Group 2 QLC, only the first 8 or 16 dual port RAM locations aavailable to the DIOB (depending on the JS10 and JS16 jumper settings, asdescribed inSection 2). The data at these locations can be accessed throughstandard DPU scan routines.

When planning and implementing a Group 2 QLC application, the followingreference documents should be available:

• For information on Q-card data formats, see“Q-Line Installation Manual”(M0-0053).

• For information on WDPF point record types and fields, see “Record TypesUser’s Guide” (U0-0131).

• For general information on DPU application programming, includingprocedures to add points to the database, see “MACApplicationUtilities User’sGuide” (U0-0136).

Figure4-5 illustrates the interface between the DIOB and the QLC static RAMQLC G02.

The Group 2 QLC can be used for input or output of analog or digital points,depending on the type of Q-card which is emulated. The QLC application progmust use the correct data formats for the emulated cards. That is, the input sethe DIOB must follow the expected pattern in order to be correctly interpretedthe DPU scan routine. Similarly, the application program must be able to interthe data output from the DIOB.

Although any Q-card can be emulated, the following types are recommended

• QAW (analog input)

• QAO (analog output)

• QBI (digital input)

• QBO (digital output)

For both the QAW and QAO, the lower 12 bits of the data word represent a renumber (Intel floating point) value. The QAW uses the upper 4 bits for sign aerror flags, as shown inFigure4-6. For the QBI and QBO, each bit of the data worrepresents a digital value.

If emulating any other card type, the user must determine the required data formthe emulated card, and ensure that the format is followed precisely. For informaon the Q-card data formats, refer to “Q-Line Installation Manual” (M0-0053).

To access the Group 2 QLC using the DPU scan routines, enter point recordsthe DPU database, using the following guidelines:

• Enter the appropriate point record type (AI for analog input, AL for analogoutput, DI for digital input, or DL for digital output).

• Assign the appropriate card type (CD field) for the card to be emulated.

• Determine the hardware address offset (HW field) based on the QLC RAMlocation to be accessed.

• Assign conversion coefficients (using the CV and CI fields) as required byapplication.

• Other required and optional record fields should be initialized as required byapplication.

There is a one-to-one correspondence between the DIOB addresses and avamemory locations for the Group 2 QLC, as shown below:

The QLC application program must use the correct static RAM locations,corresponding to the hardware address assigned to each point.

The following application notes may be helpful in planning the QLC applicatioand in programming the QLC.

Note

These application notes apply to both groups of theQLC, except where specifically noted.

1. Typically, the programs to be run in the QLC will be specified in theAUTOEXEC.BAT file. As in any other IBM-compatible microcomputer,AUTOEXEC.BAT will be executed automatically when the QLC is reset orpowered-up.

2. When defining an AUTOEXEC.BAT file (to run an application in a QLCwithout a connected external personal computer), it may be useful to includecommand BREAK=ON. This will allow the user to connect an externalpersonal computer, start the EXTPC program, and useControl-C to interruptthe program running in the QLC.

3. When the QLC is linked to the external personal computer, a QLC rebootbe performed by pressingCtrl-Shift-Delete (at the personal computerkeyboard). If the left-handShift key is used, a warm reboot will be performeda cold reboot will be performed if the right-handShift key is used.

4. DOS DEBUG can be used (as on an IBM-PC); however, it will not correctdisplay 80C186 extended instructions. Microsoft CODEVIEW may be usedsequential mode only and must be invoked with the /D option. For additioinformation, refer to the applicable manufacturer’s documentation.

5. For any application which will require CRT output or keyboard input, theexternal personal computer may be left in place after initialization. Howevthe graphics capability is extremely limited.

Once the external personal computer is removed, programs which requireoutput or keyboard input should not be run on the QLC.

6. Video display capability is only supported through the BIOS. Do not use asoftware that reads or writes directly to the video memory.

7. Due to differences between the QLC and IBM-PC hardware, due not usesoftware that attempts to program timers, the interrupt controller, or any oprocessor peripherals.

8. Figure 4-7 provides a memory map for the 80C186 processor. Note thefollowing points:

— The 640 Kbytes DRAM (addresses 00000H - 9FFFFH) are available forby the DOS operating system and DOS application programs.

— For purposes of communication with the DPU, store data in the dual pRAM. The available RAM addresses depend on the group of QLC, asdescribed inSection 4-2.1 andSection 4-2.2.

— The remaining memory addresses are reserved for Westinghouse use

9. Specific I/O addresses are available to the user application to read the stathe configuration switches (SW3), write to the eight status LEDs (LE2 - LEand read or write to the SBX serial port.Table 4-1 describes the I/O addressewhich may be accessed by the user application. All other I/O addresses areserved for Westinghouse use.

10. The QLC incorporates a watchdog timer which can be used by the applicaif desired. The timer will time-out after 160 msec, unless the applicationprogram writes any byte value to I/O address 0900H.

11. When using the Group 1 QLC, the watchdog status is available to the DPthrough the QLCSTAT algorithm. If the watchdog timer feature is notimplemented in the user’s application, the applicable status bit will always eq0. If a QLC watchdog time-out is detected, the Group 1 QLC can be resethe DPU using the QLCCMD algorithm. (Refer to“Standard ControlAlgorithms” (U0-0106) for additional information on the QLCSTAT andQLCCMD algorithms.)

12. After the QLC is reset, the DIOB registers (dual port RAM) are uninitializeThe application program in the QLC should initialize these memory locatioas necessary.

This section discusses the File Transfer program, which is used to transfer filbetween aMaster Station (Engineer Station, PCH, or WEStation.) and a QLC caover the WDPF Highway.

The following topics are included in this section:

• File transfer overview (Section 5-2).

• Using file transfer at the QLC (Section 5-3).

• File transfer initiation (Section 5-4).

• File transfer message received by the DPU (Section 5-5).

• File transfer error messages (Section 5-6).

5-2. File Transfer Overview

The QLC card is similar to an IBM-compatible personal computer and uses amodified IBM PC Basic Input/Output System and the DOS operating system. Sthe QLC’s architecture and operating system are compatible with an IBM-compatible personal computer, the QLC can execute programs written usingcommercially available compilers.

In order to communicate with a QLC over the WDPF Highway, the DPU mustused as an interface. For filedownloads, the file data is sent from a Master Stationover the highway to the DPU that contains the QLC card. The DPU will then pthe file to the QLC through the QLC’s DIOB dual-port registers.

For fileuploads, file data is passed from the QLC to the DPU through the QLCDIOB dual-port registers. The DPU will then send the file to the Master Station othe highway.

The program provides the following advantages:

• The ability to remotely access files on a QLC without having to connect anexternal personal computer to the QLC.

• The ability to copy files to/from the QLC without having to interrupt anapplication program at the QLC.

• The ability to use a standard Master Station to perform the entire upload/download of files to the QLC using the DPFCOPY application program.DPFCOPY is used to perform a highway file transfer between an Master Staand an HSR, SIU, TCU, or another Master Station.

For more information on the DPFCOPY program, see one of the following manudepending on the platform being used:

• “Engineer Station Support Utilities” (U0-0281) — Classic.

• “WEStation Support Utilities for Classic Drops” (U0-8201) — WEStation.

• “ Introduction to PCH User’s Guide” (U0-2400) — PCH.

• “Introduction to the ISA-PCH User’s Guide” (U0-2480) — PCH.


5-3. Using File Transfer at the QLC

ust

r/

ility.


In order for the File Transfer program to be used, the following modifications mbe made to a QLC application:

• Reserve registers 1920 through 2047 of the dual port RAM for file transfeGPM capability.

• Link modulexf010a.obj into the application.

• Include the modulexf010a.h into the main application.

• Include a periodic call to the routinecheck_file_xfer in the main loop of theapplication.

There are two methods that may be used to implement the file transfer capabThese methods are discussed below.

Method 1

Using Method 1, downloaded files will be lost on QLC reset.

: /* main application include files */:#include “xf010a.h” /* file transfer include file */:void main(.........){ : /* main application initialization */ : while (1) /* main application loop */ { : : check_file_xfer(); /* check for file transfer */ }}



Method 2

Using Method 2, downloaded files willnot be lost on QLC reset.

: /* main application include files */:#include <process.h> /* needed for spawn function */:#include “xf010a.h” /* file transfer include file */:void main (.........){ : /* main application initialization */ : while (1) /* main application loop */ { : :

if (check_file_xfer()==END_DOWNLOAD) /* check for file xfer */ {

file_xfer_ptr->cmd = DO_BAKFLASH; /* disable incoming filexfer */ spawnlp (P_WAIT, “bakflash.exe”,”bakflash”,NULL) ; /* dobakflash */

file_xfer_ptr->cmd = 0; /* re-enable incoming filexfer */ /* Note: bakflash.exe must be on QLC hard disk */ } }}


5-4. File Transfer Initiation

PY

data.

ion.t the

)


WDPF Highway file transfers are initiated at a Master Station using the DPFCOapplication program. See the appropriate user’s guide for more information onDPFCOPY according to the platform being used (Classic, PCH, or WEStation).

The DPFCOPY program performs the following functions:

• Interprets a command line entered by the user.

• Verifies that parameters entered by the user are valid.

• Reports any invalid parameters.

• Establishes a link with a slave drop.

• Sends and receives file data to/from the slave drop.

• Reports any errors that have occurred during the upload or download of file

• Terminates link with the slave drop.

• Reports successful file transfers to the user.

Example

The following is an example of using DPFCOPY at the Classic Engineer StatFor a file transfer to the QLC card, DPFCOPY must be invoked by the user aClassic Engineer Station with the following command line:

DPFCOPY <direction> <master-file> <slave-file> <slave-drop> <qlc-addrs>

Note

DPFCOPY is located in the\WDPF\SHC\BINdirectory on the PCH.

<direction> = UP (upload file from QLC to Engineer Station)DOWN (download file to QLC from Engineer Station

<master-file> = Name of the file at the Engineer Station

<slave-file> = Name of the file at the QLC

<slave-drop> = Drop number of the DPU where QLC resides

<qlc-addrs> = Hardware address of the QLC



ishisir

tosion

ueng

theC.

Hardware Address

The<qlc-addrs>parameter was added so that the DPU would be able to distinguwhich QLC was to upload or download a file. The DPU must know which QLCto download or upload a file. The DPU distinguishes between its QLCs by thehardware addresses.

The<qlc-addrs>parameter is required only when downloading/uploading a filethe QLC. The user must have the latest version of the DPFCOPY program (ver1A or above), as released in level 7.2, to enter the<qlc-addrs> parameter on thecommand line.

The<qlc-addrs> is read from the command line as either a 4-digit decimal valor a 3-digit + trailing hexadecimal value. Valid QLC addresses lie in the followiranges:

— Decimal value: 2 through 1022

— Hexadecimal value: 2H through 3FEH

For file downloads, the QLC file name will be the file to create or overwrite at QLC. For file uploads, the QLC file name will be the file to upload from the QL

5-5. File Transfer Message Received by the DPU

When the DPU receives the file transfer message from the Engineer Station, itinterpret the message as a file transfer message. The DPU will check to deteif any of the following are true:

• A TCU or QLC file transfer is already in progress.

• The DPU is not in online mode.

• The QLC address specified by the user is not valid with the number of MB

• The QLC is currently processing a GPM message request.

• The QLC at the specified address is not responding.

If any of the above conditions are true, an error message will be displayed to theat the Engineer Station, and the file transfer will be aborted.

Upon receipt of a file transfer message, the DPU must prepare for the transfer odata by establishing a 10K byte receive/transmit buffer. A portion of Control Ar4 will be used for this buffer.

It must be noted that to implement the file transfer capability, only 48K of ContArea 4 will be available for loops, ladders, and text algorithms.

This means that the user must re-translate the source code of the DPU so thcontrol that was placed in Area 4 will not be overwritten during a file transfer.

This appendix contains example application programs for the QLC. Theseexamples (written in C language) illustrate the following:

• Functions used to transfer values to and from the DIOB registers.

• Test of QLC functions (access DIOB registers and QLC status register, andQLC LEDs) from the external personal computer.

• Online performance calculation (obtain values from the DPU, calculate anreturn a value to the DPU, and write to a dumb terminal through the SCOMserial port).

In addition, sample DPU application entries are shown (corresponding to theperformance calculation example). Alternatives are presented for DPU applicausing a Group 1 or Group 2 QLC.

The following listing contains functions used to obtain and store DIOB data, to rthe QLC status register, to write to the QLC LEDs, and to write ASCII data toSCOM serial port.

Note

These example functions are not applicable tothe Group 2 QLC.

As described inSection 4, the Group 2 QLC requires that the DIOB register damust be in the correct format for the emulated Q-card. Therefore, for a GroupQLC, the functions would need to handle the conversion between integer or floapoint format and the required bit pattern. Also note that "format 2" (real value wstatus) would not be available for a Group 2.

This example program illustrates how the QLC can be used for online performacalculations. In this example, the following steps are performed:

• Three point values are obtained from the DIOB registers.

• An adjusted value (for one of the points) is calculated.

• The adjusted value is written to a DIOB register, where it can be read by the D

• The original value and the adjusted value are displayed on a dumb terminconnected to the SCOM serial port.

These steps are repeated once every 10 seconds.

To implement a complete performance calculation, the DPU application must bup to transfer the point values. Sample DPU application entries are shown latthis appendix.

The following example screens illustrate typical DPU application entries (usingMAC Utilities Edit function) for a Group 1 QLC.

These examples correspond to the example QLC performance calculationapplication inSection B-5. However, only samples are shown (one QLCAINalgorithm, one QLCAOUT algorithm, and one originated analog point). Tocomplete this example application, additional points would need to be defined

For a Group 1 QLC, the point hardware address offset (HW field) will be set to 0each point used by the QLC input and output algorithms. The appropriate QLhardware address offset and starting DIOB register must be defined in theapplicable algorithm fields, as shown. Also, for AI points, the card type (CD fieof each point will be set to 67 for a QLC G01.

For additional information on the QLC algorithms, see "Standard ControlAlgorithms"(U0-0106). For additional information on adding algorithms and pointo the DPU application, see"MAC Application Utilities User’s Guide" (U0-0136).For additional information on point record types and fields, see "RecordTypesUser’sGuide" (U0-0131).

The following example screens illustrate a typical DPU application entry (usingMAC Utilities Edit function) for a Group 2 QLC.

This example corresponds to the example QLC performance calculation applicain SectionB-5. However, only a sample is shown (one originated analog point).complete this example application, additional points would need to be defined

For a Group 2 QLC, each point’s hardware address offset (HW field) must correspto the QLC card hardware address and appropriate DIOB register in the QLC. Inexample, the QLC card’s hardware address is 0010H, and the point value is towritten to register 0. Therefore, the hardware address offset is specified as 0020Htimes the hardware address, with no additional offset for this point).

The point’s card type (CD field) will depend on the Q-card to be emulated. In example, a QAO G01 is emulated (CD = 21).

For additional information on adding points to the DPU application, see"MACUtilities User’sGuide"(U0-0136). For additional information on point record typeand fields, see "Record Types User’s Guide" (U0-0131).

Appendix C. QLC in CE Mark CertifiedSystems

C-1. Section Overview

The QLC configured with an SCOM board is applicable for use in CE Markcertified systems. The following rules apply:

1. The QLC configuration drawing number is 1B30021.

2. The QLC must be used in the CE Mark certified cabinet. This cabinet inclua transition panel for the SCOM serial port cable. Connections from the (fiedevice to the SCOM port arenot brought directly to the SCOM board. Theconnection is brought to the transition panel. This provides a solid earth groconnection for the cable shield. There is an internal cable that connects thSCOM port to the connector at the transition panel. The cables used to conan external device to the transition panel are as follows:

• Westinghouse part number 5A26123 to connect the QLC/SCOM transitpanel connector to a 25-pin male D connector at the external device.

• Westinghouse part number 5A26124 to connect the QLC/SCOM transitpanel connector to a 9-pin male D connector to the external device.

3. If the connection to the QLC serial port is permanent, it must be handled insame manner as the SCOM connection (see #2 above).

These cables are available in several lengths, identified by group number, as sin TableC-1. For example, part number 5A26123G03 identifies a 4-foot cable uto connect the QLC SCOM port (at the transition panel) to a 25-pin personalcomputer serial port.

These cables may also be constructed by the user, as described later in this app

Note

When constructing cables, the user must ensure thatWestinghouse specifications are followed.Otherwise, the CE Mark certification is invalid.
