Table SpecificationsTable Description and OperationSection 2IntroductionThis section explains the functionality of the Harmony bridgecontroller BRC using block diagrams and text.

Block diagramsdivide the operation of the Harmony bridge controller. OperationThe BRC module incorporates the power of a second generationbit microprocessor operating at 32 megahertz. This iscoupled with bit wide memory design with an optimizedinterface. The microprocessor supplies superior performancecapable of supplanting the need for external mainframes orminicomputers. In some processes, the effects of a control failure in the systemcan create dangerous situations or cause economic loss.

Toreduce the possibility of these problems occurring, redundantmodules provide fail-safe control. Each module uses a redundant highspeed communication channel to accomplish this function.

Ifthe primary module fails, the backup module is waiting inst and by mode and immediately takes over. The backup modulehas the same control strategy loaded in its memory as the primaryBRC module and is ready to assume control. When operatingin Hnet communication mode, the redundantcommunication channel insures that single point failures willnot prevent the backup module from being in a state of readinessto take over.

While the BRC module is controlling a process, it also executesdiagnostic routines. Circuitryhardware and firmware during normal operation. If thediagnostic routines discover a module hardware or softwareproblem, it makes that information available to the operator.

The operator has access to this information through statusLEDs on the module faceplate and through reports received onthe human system interface HSI in module status bytes.

This stationlink can h and le up to 64 IISAC01 stations at a kilobaudrate or eight stations at a five-kilobaud rate. Varioush and shake options are available via jumper configurations onthe termination unit.

CircuitryThe BRC module has all the needed circuitry to operate as ast and -alone controller. Direct memory access DMA operationis supported for the station link. Figure shows a block diagramof the BRC circuitry. MicroprocessorThe microprocessor is responsible for module operation and control. The BRC microprocessor is a bit processor thatruns from a megahertz clock. The microprocessor executessynchronous access to long word memories and an asynchronousaccess to all byte ports.

Since the microprocessor isresponsible for module operation, it communicates with allblocks of the BRC circuitry. The microprocessor operating systeminstructions and the function code library reside in theread only memory flash ROM. The microprocessor carries outall control responsibilities as it executes the control strategyset up in its function block configuration.

The microprocessor constantly triggers the machine fault timer MFT circuit. If the microprocessor or software fails, the MFTcircuit times out, issues a board wide reset, and the statusLED turns red. This condition is a fatal module error. Functional Block DiagramClock and Real-Time ClockMemoryThe clock section provides the clock signals to drive the microprocessor and associated peripheral devices.

The flash ROM memory holds the operating system instructionsfor the microprocessor. The SRAM memory provides temporarystorage and a copy of the system configuration. NVRAM memory retains whatever informationit has, even when it loses power.

The DMA section enables the various communication links todo direct data transfers to and from RAM memory without processorintervention. The DMA process greatly reduces the amount of work themicroprocessor needs to do when making data moves. Thisgreatly increases the speed of the BRC module by notoverloading the microprocessor with the work associated withdata moves. The microprocessor does not have to execute datamoves and is free to do other tasks.

The Controlway is a high speed communication bus betweenHarmony rack controllers. The BRC module uses this bus tocommunicate with other control modules within a Harmonycontrol unit. It provides a one-megabaud, peer-to-peer communicationlink that can support up to 32 devices. The Controlwayinterface is provided by a custom integrated circuitthat links the BRC module to the Controlway.

It has full DMAcapabilities allowing for quicker operation , and two independent,redundant channels. The redundant Controlway channels run through two paths onthe module mounting unit backplane circuit. The BRC moduletransmits and receives data over both channels simultaneously. By receiving data through two channels, the BRCmodule can check its integrity.

In this way, the Controlwayminimizes the potential that a failure on a circuit board orbackplane will cause loss of module communication. The Controlway interface also allows the BRC module to runon module bus by operating in an The redundancy link is a dual parallel link between a primary and backup BRC module in redundant configurations.

As theprimary module executes, the backup module waits in st and bymode and receives a copy of block outputs over this link.

If forany reason the primary module fails, the backup takes overwithout any process interruption. If the firmware revision level is different and a failoveroccurs, the redundant BRC module may operate erratically. Two parallel channels of data and control signals connect byway of a processor bus adapter board. Both channels have parityprotection. The processor adapter board mounts on the rearof a module mounting unit with the proper adapter bracketsinstalled.

It uses cables to connect to the Harmony blockmounting columns. The microprocessor canselect one of two modes of operation: DMA or auto mode. TheBRC software selects the mode of operation. Mode selection isbased on optimizing the number of bytes to be transferred.

Ineither mode of operation, the microprocessor does not need towait for each byte to transfer as in previous controllers. This section also contains latches whose outputs connect tothe status and error LEDs. This section monitors redundantmodules and outputs a signal to the LEDs of the primary module.

Upon failover, this output de-energizes and the output ofthe backup module energizes as it takes over. Both serial channels are dedicated for languagesupport C or Basic or sequence of events recording. Circuitryboard supplies the serial channels with h and shaking signals. Clock signals for the baud rate generator are derived from anon-board, 7. St and ard D-type connectors are available on the terminationunit. To provide better noise immunity, both channels transmit and receive differential serial signals based on the RS st and ard.

These signals are converted to normal RSC voltagelevels by the termination unit. Each channel is capable of supportingst and ard RSC baud rates up to The termination unit also provides optical isolation to eliminatethe possibility of introducing ground loops into the systemfrom improper cable shield grounding.

This link controls the serial communicationbetween the BRC module and the control stations. Eight stations can be supported at the five-kilobaud rate and up to 64 stations can be supported at the kilobaudrate. The Hnet interface derives all other powerrequirements from the 5 VDC logic power.

Power for the moduleis supplied via the module mounting unit connection to theBRC module P1 connector. The PBA boarduses this power for Hnet termination, and to power the isolationrelays. Read, underst and , and complete thesteps in the order they appear before operating the BRCmodule. If no Hnet communication and termination unit is needed, a BRC redundancy kitmay be used to support redundancy instead of the PBA boards.

NOTE: This module uses connections to the module mounting unit backplanethat served other functions in earlier Net work 90 systems. To avoid potentialmodule damage, evaluate your system for compatibility prior to module installation. Doing so allows the installation ofthe BRC module in a module mounting unit that uses VDC and limits communicationto module bus. Refer to Table for more information about settingjumper J3. The kit grounds a technician and the static dissipative work surface to the same ground point to preventdamage to the modules by electrostatic discharge.

Use Static Shielding Bag. Keep the modules in the staticshielding bag until you are ready to install them in the system. Save the bag for future use. Ground Bag Before Opening.

Use the original packing material and container to store thehardware. Store the hardware in an environment of good air quality,free from temperature and moisture extremes.

This section explains how to configure and install the BRCmodule. After installing the module, a function blockconfiguration must be created to define the functions the modulewill perform.

The BRC module has four configurable dipswitches, and fourjumpers. Each dipswitch has eight poles. Figure shows thelocation of the dipswitches and jumpers on the circuit board. Dipswitch SW2 sets moduleoptions, enables special operations, and enables diagnosticoperations.

Dipswitch SW4 sets module mounting unit and memory options. Dipswitch SW3 is not used. Jumper J1 enables or disables the machine fault timer MFT. Jumper J4 is reserved for useby ABB engineering.

Dipswitch poles marked not used must be set to the defaultsettings listed in the appropriate table. The BRC module maynot operate properly if these dipswitches are improperly set. Since factory settings do not reflect default settings, it isimperative that all dipswitch settings be checked before puttingthe module into operation.

The BRC module can have anaddress from zero through Table explains the functionsset by dipswitch poles one through three. Dipswitch poles fourthrough eight set the module address. Table shows examplesof how to set the address. Record the module address settingin the user setting portion of the table. All modules within a process control unit must beset to communicate on the same type of communication bus, either Controlwayor module bus.

Module addresses of redundant BRC modules must be identical. Dipswitches and JumpersTable Refer to Table foroption setting information.

The options listed in this tableTable Normal operation options areenabled when dipswitch SW2 pole one is set to closed on. Ifdipswitch SW2 pole one is set to open off , special operationsare enabled.

The special operations feature provides a means to configurethe BRC module to perform a one-time special operation ratherthan entering its normal mode of operation. Setting dipswitchSW2 pole one to open off enables the special operation mode. The compact configuration function movesconfigured function blocks to the top of the NVRAM while moving freespace to the bottom. To enable this function, open the pole and insertthe module into the module mounting unit. After a short time directlyproportional to the configuration size , the module will return to themode it was in prior to being reset for the compact operation.

This operation destroys erases the module function blockconfiguration. Leave poleopen; insert module into module mounting unit.

When group A LEDs1, 2 and 4 are on, remove the module, put the pole in the closed position, and insert the module. The module is now ready to be configured. NOTE: This pole must remain closed for normal operation. This setting is used by development personnel and should never be used for normal operation. The checksum provides additionalmodule integrity and should be used whenever the module is controlling a process. Leaving this option enabled causes the configuration to be compacted every time the module is reset, thereby increasing thestartup time.

This increase becomes more substantial as the size of the configuration increases. Therefore, do not leave thisoption enabled longer than necessary. Disabling this option stops any further compacting operations. It does not uncompact anypreviously compacted configuration. When redundancy is used, poles one through seven on the redundant BRC module are set the same as the primary BRCmodule. Pole eight is set to closed on for the primary module and to open off for the secondary module.

Dipswitches and JumpersPoles two through eight select the special operation. The followingsteps explain how to set the BRC module for specialoperations and reset it for normal operation. Table showsthe dipswitch settings and explains each special operation. To use special operations Set dipswitch SW2 pole one to open off.

Set poles two through eight per Table Begin with specialoperation two. This operation instructs the BRC module togenerate time information with point data. Remove the BRC module. Repeat Steps 2 through 8 for any other special operationdesired. NOTE: Do special operation two as the first step of the module installation. For time-stamping, do special operation six next. Dipswitches and Jumpers7. When all special operations are complete, reset pole one ondipswitch SW2 to the closed on position.

Poles two through eight module options should be set forthe desired BRC operation per Table Insert the BRC module in its slot. It will begin normaloperation. All poles should be set to closed on. This dipswitchshould be set to the user settings shown in Table These jumpers are for special hardware applications.

Module Mounting Unit PreparationTable Refer toTable for an explanation of the functions set by jumpers. It is used todisable the machine fault timer circuit.

If this function is disabled jumper pinsconnected and a problem develops in the BRC module, the module will nothalt, which may result in configuration corruption and unpredictable moduleoutputs. Must remain open for normal operation. This setting must be used if dipswitch SW5 selectsControlway. J4 Open Not used. Used by ABB service personnel. The J2 setting does not affect the module during normal operation. Module placement within the module mounting unit is important. Failure to do so will result in contactwith cabinet areas that could cause severe or fatal shock.

Controlway CableNo dipshunts are required if only Hnet is being used. One dipshunt goes between each moduleslot to maintain bus continuity.

Refer to the Function Code Applica-tion Manual for details on function code NOTE: Because of high speed transaction constraints, a maximum of eightrelated module mounting units Controlways linked by cable can be installed inone enclosure.

The number of interconnected module mounting units shouldbe kept to a minimum to avoid crosstalk and interference. Controlways cannotbe cable linked from enclosure to enclosure. Install the Controlway cable in module mounting units asfollows Attach one end of the cable twisted three-wire to the bottomthree tabs on the lower left of the module mounting unitbackplane facing from behind.

Refer to Figure Attach in the same sequence the other end of the cable tothe bottom three tabs on the lower left of the next modulemounting unit backplane. The termination unit provides a connectionfor the two auxiliary serial ports and a direct five-kilobaudor kilobaud station link. A processor bus adapter mounting bracket is required toinstall the PBA board. Failureto do so will result in contact with cabinet areas that couldcause severe or fatal shock.

Turn off power to the cabinet. Install one PBA mounting bracket to the top of the modulemounting unit backplane assembly using five screws, flatwashers, and spacers. Install the remaining mounting bracket to the bottom of thebackplane assembly using five screws, flat washers, and spacers. There are two cable and terminator installation procedurespresented.
