The Tricon is a fault-tolerant controller based on a Triple-ModularRedundant (TMR) architecture.

Introduction

What is Fault-Tolerant

Control?

A fault-tolerant control system identi-fies and compensates for failed controlsystem elements and allows repairwhile continuing an assigned taskwithout process interruption. A high-

integrity control system such as theTricon is used in critical process appli-cations that require a significant degreeof safety and availability.

What is the Tricon?

The Tricon is a state-of-the artcontroller that provides fault toleranceby means of Triple-Modular Redundant(TMR) architecture. TMR integratesthree isolated, parallel control systems

and extensive diagnostics in onecontrol system. The system uses two-out-of-three voting to provide high-integrity, error-free, uninterruptedprocess operation with no single pointof failure.

The Tricon controller uses three iden-tical channels. Each channel indepen-dently executes the applicationprogram in parallel with the other twochannels. Specialized hardware/soft-ware voting mechanisms qualify andverify all digital inputs and outputsfrom the field, while analog inputs aresubject to a mid-value selectionprocess.

Because each channel is isolated fromthe others, no single-point failure in anychannel can pass to another. If a hard-ware failure does occur on one channel,the other channels override it. Mean-while the faulting module can easily be

removed and replaced while thecontroller is online without interruptingthe process.

Setting up applications is simplifiedwith the triplicated Tricon system,because it operates as a single controlsystem from the users point of view.The user terminates sensors and actua-

tors at a single wiring terminal andprograms the Tricon with one set ofapplication logic. The Tricon managesthe rest!

Extensive diagnostics on each channel,module, and functional circuit immediately detect and report operationalfaults by means of indicators or alarms

Introduction

All diagnostic fault information isaccessible by the application programand the operator. The program or the

operator can use diagnostic data tomodify control actions or direct mainte-nance procedures.

Other key features of the Triconcontroller that ensure the highestpossible system integrity are:

No single point of failure

Ability to operate with 3, 2 or 1Main Processor before shutdown

Fully implemented and transparent

triplication Comprehensive system diagnostics

Complete range of I/O modules

Dual and single I/O modules forsafety-critical points with a limitedneed for availability

Remote I/O up to 12 kilometers (7.5cable miles) away

Simple, on-line module repair

Unsurpassed reliability and

availability

What are Typical User

Applications?

Each day the Tricon supplies increasedsafety, reliability and availability to aworldwide installed base. Thefollowing are a few typical applica-tions. For details on the Tricons valueto your applications, ask your salesrepresentative for additional documen-tation and customer references.

Emergency Safety Shutdown

(ESD)

The Tricon provides continuous protec-tion for safety-critical units in refin-eries, petrochemical/chemical plantsand other industrial processes. Forexample, in reactor and compressorunits, plant trip signalsfor pressure,product feed rates, expander pressure

equalization and temperaturearemonitored and shutdown actions takenif an upset condition occurs. Traditional

shutdown systems implemented withmechanical or electronic relays provideshutdown protection but can also causedangerous nuisance trips.

The Tricon increases system integrity,providing automatic detection and veri-fication of field sensor integrity, inte-grated shutdown and controlfunctionality, and direct connection tothe supervisory data highway forcontinuous monitoring of safety-crit-ical functions.

Boiler Flame Safety

Process steam boilers function as a crit-ical component in most refinery appli-cations. Protection of the boiler fromupset conditions, safety interlock fornormal startup and shutdown, andflame-safety applications are combinedby one integrated Tricon system. Intraditional applications, these functionshad to be provided by separate, non-integrated components. But with thefault-tolerant, fail-safe Tricon

controller, the boiler operations staffcan use a critical resource more produc-tively while maintaining safety at orabove the level of electromechanicalprotection systems.

Turbine Control Systems

The control and protection of gas orsteam turbines requires high integrityas well as safety. The continuous oper-ation of the fault-tolerant Triconcontroller provides the turbine operatorwith maximum availability while main-

taining equivalent levels of safety.Speed control as well as start-up andshutdown sequencing are implementedin a single integrated system. Unsched-uled outages are avoided by using hotspares for the I/O modules. If a faultoccurs in a module, a replacementmodule is automatically activatedwithout operator intervention.

Offshore Fire & Gas Protection

The protection of offshore platformsfrom fire and gas threats requirescontinuous availability as well as reli-ability. The Tricon provides this avail-ability through on-line replacementoffaulty modules. Faults in individualmodules, field wiring and sensors aremanaged automatically by built-indiagnostics. Analog fire and gas detec-tors are connected directly to theTricon, eliminating the need for tripamps. An operator interface monitorsfire and gas systems as well as diagnos-tics for the Tricon controller and its

attached sensors. Traditional fire andgas panels can be replaced with a singleintegrated system, saving costly floorspace while maintaining high levels ofsafety and availability.

What is TriStation?

The TriStation 1131 Developer'sWorkbench is an integrated tool fordeveloping, testing and documentingapplications for the Tricon. TriStationcomplies with the IEC 1131 Interna-tional Standard for ProgrammableControllers and follows the MicrosoftWindows guidelines for graphical userinterfaces. Seepage 61 for more infor-mation.

What about Communication

Capabilities?

Optional modules enable the Tricon tocommunicate with other Tricons on apeer-to-peer network and with:

Modbus masters and slaves

Distributed Control Systems (DCS)

Operator workstations

Host computers accessed by meansof TCP(UDP)/IP/802.3 protocol

The Tricon is designed with a fully triplicated architecturethroughout, from the input modules through the Main Processors(MPs) to the output modules.

Theory of Operation

Fault tolerance in the Tricon is achievedby means of a Triple-Modular Redun-dant (TMR) architecture. The Triconprovides error-free, uninterruptedcontrol in the presence of either hardfailures of components, or transientfaults from internal or external sources.

The Tricon is designed with a fully trip-licated architecture throughout, fromthe input modules through the MainProcessors to the output modules.Every I/O module houses thecircuitry for three independent legs.Each leg on the input modules readsthe process data and passes thatinformation to its respective MainProcessor. The three Main Proces-sors communicate with each otherusing a proprietary high-speed bus

system called the TriBus.Once per scan, the three MainProcessors synchronize and commu-nicate with their two neighbors overthe TriBus. The Tricon votes digitalinput data, compares output data,and sends copies of analog inputdata to each Main Processor.

The Main Processors execute the user-written application and send outputsgenerated by the application to theoutput modules. In addition to voting

the input data, the TriBus votes theoutput data. This is done on the outputmodules as close to the field aspossible, in order to detect and compen-sate for any errors that could occurbetween the Tricon voting and the finaloutput driven to the field.

For each I/O Module, the system cansupport an optional hot-spare module

which takes control if a fault is detectedon the primary module during opera-tion. The hot-spare position can also beused for on-line system repairs.

Main Processor Modules

A Tricon system contains three MainProcessor (MP) Modules to controlthree separate legs of the system. EachMain Processor operates in parallel

with the other two Main Processors, asa member of a triad.

A dedicated I/O Processor (IOP) oneach Main Processor manages the dataexchanged between the Main Proces-sors and the I/O modules. A triplicatedI/O Bus is located on the chassis back-plane and is extended from chassis tochassis by means of I/O Bus Cables.

As each input module is polled, the newinput data is transmitted to the MainProcessor over the appropriate leg ofthe I/O Bus. The input data from eachInput Module is assembled into a tablein the Main Processor and stored in

memory for use in the hardware votingprocess.

The individual input table in each MainProcessor is transferred to its neigh-boring Main Processors over the proprietary TriBus. During this transfer,hardware voting takes place. The

TriBus uses a Direct Memory Accessprogrammable device to synchronize,transmit, vote and compare data amongthe three Main Processors.

If a disagreement is discovered, thesignal value found in two out of threetables prevails, and the third table iscorrected accordingly. One-time differences which result from sample timingvariations can be distinguished from a

pattern of differing data. The threeindependent Main Processors eachmaintain data about necessary correc-tions in local memory. Any disparity isflagged and used at the end of the scanby the built-in Fault Analyzer routinesto determine whether a fault exists on aparticular module.

Theory of Operation

After the TriBus transfer and input datavoting have corrected the input values,these corrected values are used by the

Main Processors as input to the user-written application. (The application isdeveloped in the TriStation and down-loaded to the Main Processors.) The 32-bit main microprocessor and a math co-processor execute the user-writtenapplication in parallel with the neigh-boring Main Processor Modules.

The user-written application generatesa table of output values based on thetable of input values, according to therules built into the application by the

customer. The IOP on each MainProcessor manages the transmission ofoutput data to the output modules bymeans of the I/O Bus.

Using the table of output values, theIOP generates smaller tables, eachcorresponding to an individual outputmodule in the system. Each small tableis transmitted to the appropriate leg ofthe corresponding Output Module over

the I/O Bus. For example, MainProcessor A transmits the appropriatetable to Leg A of each Output Module

over I/O Bus A. The transmittal ofoutput data has priority over the routinescanning of all I/O modules.

The IOP manages the data exchangedbetween the Main Processors and thecommunication modules using thecommunication bus, which supports abroadcast mechanism.

The Model 3008 Main Processorsprovide 16 Megabytes DRAM each forV9 Tricon Systems. The RAM is used

for the user-written application,sequence-of-events data, I/O data, diag-nostics and communication buffers. Inthe event of an external power failure,the integrity of the user-writtenprogram and the retentive variables isprotected for a minimum of six months.

The Main Processor Modules receivepower from dual Power Modules andpower rails in the Main Chassis. A

failure on one Power Module or powerrail will not affect the performance ofthe system.

Bus Systems and

Power Distribution

Three triplicated bus systems are etchedon the chassis backplane: the TriBus,the I/O Bus and the CommunicationBus.

The TriBus consists of three indepen-dent serial links operating at 25MBaud(with Model 3008 MPs). The TriBussynchronizes the Main Processors atthe beginning of a scan. Then eachMain Processor sends its data to itsupstream and downstream neighbors.The TriBus performs one of two func-tions with the data:

Transfer of data onlyfor I/O,diagnostic and communication data.

Comparing data and flaggingdisagreementsfor previous scans

output data and memoryof user-written applica-

tion.An important feature of theTricons fault-tolerantarchitecture is the use of asingle transmitter to senddata to both the upstreamand downstream MainProcessors. This ensuresreceipt of the same data bythe upstream processor anddownstream processor.

Each I/O module transfers

signals to or from the fieldthrough its associated fieldtermination assembly. Twopositions in the chassis tietogether as one logical slot.The first position holds theactive I/O module and thesecond position holds thehot-spare I/O module.Termination cables are

connected to the top of the backplane.Each connection extends from thetermination module to both active and

hot-spare I/O modules. Therefore,both the active module and the hot-spare module receive the same infor-mation from the field terminationwiring.

The 375 KBaud I/O Bus transfers databetween the I/O Modules and the MainProcessors. The triplicated I/O Bus iscarried along the bottom of the back-plane. Each leg of the I/O Bus runsbetween one of the three Main Proces-sors and the corresponding legs on the

I/O module.

The I/O Bus can be extended betweenchassis using a set of three I/O BusCables.

The 2 MBaud Communication(COMM) Bus runs between the MainProcessors and the CommunicationModules.

Power for the chassis is distributedacross two independent power railsdown the center of the backplane.

Every module in the chassis drawspower from both power rails throughdual power regulators. There are foursets of power regulators on each inputand output module: one set for each ofthe legs A, B and C and one set for thestatus-indicating LEDs.

Digital Input Modules

The Tricon supports two basic types ofdigital input modules: TMR and single.The following paragraphs describedigital input modules in general,followed by specifics for TMR andsingle modules.

Every digital input module houses thecircuitry for three identical legs (A, Band C). Although the legs reside on thesame module, they are completelyisolated from each other and operateindependently. A fault on one leg

availability. Each leg conditions signals

independently and provides opticalisolation between the field and theTricon. (The 64-point High-DensityDigital Input Module is an exceptionit has no channel-to-channel isolation.)

DC models of the TMR digital inputmodules can self-test to detect stuckON conditions where the circuitrycannot tell whether a point has gone tothe OFF state. Since most safety sys-tems are set up with a de-energize-to-trip capability, the ability to detect

stuck ON points is an important featureTo test for stuck ON inputs, a switchwithin the input circuitry is closed toallow a zero input (OFF) to be read bythe optical isolation circuitry. The lastdata reading is frozen in the I/O com-munication processor while the test isrunning.

cannot pass to another. In addition, each

leg contains an 8-bit microprocessorcalled the I/O communicationprocessor which handles communica-tion with its corresponding MainProcessor.

Each of the three input legs asynchro-nously measures the input signals fromeach point on the input terminationmodule, determines the respectivestates of the input signals, and placesthe values into input tables A, B and Crespectively. Each input table is regu-

larly interrogated over the I/O bus bythe I/O communication processorlocated on the corresponding MainProcessor module. For example, MainProcessor A interrogates Input Table Aover I/O Bus A.

On TMR Digital Input Modules, all crit-ical signal paths are 100% triplicatedfor guaranteed safety and maximum

Theory of Operation

On Single Digital Input Modules, onlythose portions of the signal path whichare required to ensure safe operation aretriplicated. Single modules are opti-mized for those safety-critical applica-

tions where low cost is more importantthan maximum availability. Special

self-test circuitry detects all stuck-ONand stuck-OFF fault conditions withinthe non-triplicated signal conditionersin less than half a second. This is amandatory feature of a fail-safe system,

which must detect all faults in a timelymanner and upon detection of an input

fault, force themeasured input valueto the safe state.

Because the Tricon isoptimized for de-ener-gize-to-trip applica-tions, detection of afault in the inputcircuitry forces toOFF (the de-energizedstate) the valuereported to the MainProcessors by eachleg.

Digital Output

Modules

There are four basictypes of DigitalOutput Modules: dual,supervised, DCvoltage and AC

voltage. The following paragraphsdescribe digital output modules ingeneral, followed by specifics for thefour types.

Every digital output module houses thecircuitry for three identical, isolatedlegs. Each leg includes an I/O micro-

processor which receives itsoutput table from the I/O commu-nication processor on its corre-sponding Main Processor. All ofthe digital output modules, exceptthe dual DC modules, use specialquadruplicated output circuitrywhich votes on the individualoutput signals just before they areapplied to the load. This voter

circuitry is based on parallel-series paths which pass power ifthe drivers for Legs A and B, orLegs B and C, or Legs A and Ccommand them to closein otherwords, 2-out-of-3 drivers votedON. The quadruplicated votercircuitry provides multiple redun-dancy for all critical signal paths,

Each type of Digital OutputModule executes a partic-ular Output Voter Diag-nostic (OVD) for everypoint. Loop-back on themodule allows each micro-processor to read the outputvalue for the point to deter-mine whether a latent faultexists within the outputcircuit.

Analog InputModules

On an Analog InputModule, each of the threelegs asynchronouslymeasures the input signalsand places the results into atable of values. Each of thethree input tables is passedto its associated Main ProcessorModule using the corresponding I/OBus. The input table in each Main

Processor Module is transferred to itsneighbors across the Tricon. Themiddle value is selected by each MainProcessor, and the input table in eachMain Processor is corrected accord-ingly. In TMR mode, the mid-valuedata is used by the application program;in duplex mode, the average is used.

Each Analog Input Module is automat-ically calibrated using multiple refer-ence voltages read through themultiplexer. These voltages determinethe gain and bias that are required toadjust readings of the analog-to-digitalconverter (ADC).

Analog Input Modules and TerminationModules are available to support a widevariety of analog inputs, in bothisolated and non-isolated versions: 0-5

VDC, 0-10 VDC, 4-20 ma, thermocou-ples (types K, J, T, E), and ResistiveThermal Devices (RTDs).

Analog Output Module

The Analog Output Module receivesthree tables of output values, one foreach leg from the corresponding MainProcessor. Each leg has its own digital-to-analog converter (DAC). One of thethree legs is selected to drive the analogoutputs. The output is continuouslychecked for correctness by loop-backinputs on each point which are read byall three microprocessors. If a fault

occurs in the driving leg, that leg isdeclared faulty and a new leg is selectedto drive the field device. The designa-tion of driving leg is rotated amongthe legs, so that all three legs are tested.

Termination Modules

Various termination options are avail-able for field wiring of the Tricon High

Density chassis, including externalpanels and direct cabling. A field termination module is an electrically passivecircuit board to which field wiring iseasily attached. A termination modulemerely passes input signals from thefield to an input module or passessignals generated by an output moduledirectly to field wiring, thereby permit-ting removal or replacement of theinput or output module withoutdisturbing field wiring.

In addition, External TerminationAssemblies are available for special-ized applications. See Special Termi-nation Panels on page 46 for moreinformation.

Theory of Operation

Communication Modules

By means of the communicationmodules described in this section, theTricon can interface with Modbusmasters and slaves, other Tricons inpeer-to-peer networks, external hostsrunning applications over 802.3networks, and Honeywell and Foxboro

Distributed Control Systems (DCS).The Main Processors broadcast data tothe communication modules across thecommunication bus. Data is typicallyrefreshed every scan; it is never morethan two scan-times old.

Enhanced Intelligent

Communication

Module (EICM)

Supports RS-232, RS-422and RS-485 serial commu-nication with externaldevices at speeds up to 19.2Kbaud. The EICMprovides four serial, opto-isolated ports which caninterface with Modbusmasters, slaves, or both; ora TriStation. The modulealso provides a Centronics-compatible parallel port.

NetworkCommunication

Module (NCM)

This module supports802.3 networking over ahigh-speed 10Megabit/second data linkfor the use of Triconex-proprietary protocols andapplications (described inthe section calledCommunication Capabili-

ties later in this docu-ment). In addition, userscan write their own appli-cations using the TCP-IP/TCP-UDP protocolsee Protocols for OpenNetworks on page 59 fordetails.

Hiway Interface

Module (HIM)

This module acts as aninterface between a Tricon

controller and HoneywellsTDC 3000 Distributed Control System(DCS) by means of the Hiway Gatewayand Local Control Network (LCN). TheHIM enables higher-order devices, suchas computers and operator work-stations, to communicate with theTricon.

Safety Manager Module (SMM)

This module acts as an interfacebetween a Tricon controller and Honey-wells Universal Control Network(UCN), one of three principal networksof the TDC 3000 DCS. The SMMappears to the TDC 3000 as a safetynode on the Universal Control Network(UCN), allowing the Tricon to manageprocess-critical points within theoverall TDC 3000 environment. TheSMM transmits all Tricon aliased dataand diagnostic information to TDC3000 operator workstations in displayformats that are familiar to Honeywell

operators.

Power Supply Modules

Each Tricon chassis houses two PowerModules arranged in a dual-redundantconfiguration. Each module derivespower from the backplane and has independent power regulators for each leg.Each can support the power require-ments for all the modules in the chassisin which it resides, and each feeds aseparate power rail on the chassis backplane. The Power Modules have built-in diagnostic circuitry which checks forout-of-range voltages and over-temperature conditions. A short on a legdisables the power regulator rather than

affecting the power bus.

Advanced Communication

Module (ACM)

This module acts as an interfacebetween a Tricon controller andFoxboros Intelligent Automation (I/A)Series DCS. The ACM appears to theFoxboro system as a safety node on theI/A Series Nodebus, allowing theTricon to manage process-criticalpoints within the overall I/A DCS envi-ronment. The ACM transmits all Triconaliased data and diagnostic informationto I/A operator workstations in displayformats that are familiar to Foxborooperators.

A Tricon system consists of one Main Chassis andup to fourteen additional chassis.

System Configuration

A Tricon system is composed of a MainChassis and up to 14 Expansion orRemote Expansion (RXM) Chassis.The maximum system size is 15 chassissupporting a total of 118 I/O modulesand communication modules that inter-face with Modbus devices, other

Tricons, and external host applicationsover 802.3 networks, as well asFoxboro and Honeywell DistributedControl Systems (DCS).

The following sections provide guide-lines for chassis layout and systemconfiguration.

Chassis Layout

Two Power Supplies reside on the leftside of all chassis, one above the other.

In the Main Chassis, the three MainProcessors are immediately to the right.The remainder of the chassis is dividedinto six logical slots for I/O andcommunication modules and one COMslot with no hot spare position. Eachlogical slot provides two physicalspaces for modules, one for the activemodule and the other for its optionalhot-spare.

The layout of an Expansion Chassis issimilar to that of the Main Chassis,

except that Expansion Chassis provideeight logical slots for I/O modules.(The spaces used by the Main Proces-sors and the COM slot in the MainChassis are now available for otherpurposes.)

The Main and Expansion Chassis areinterconnected by means of triplicatedI/O Bus Cables. The maximum I/O buscable length between the Main Chassis

and the last Expansion Chassis isnormally 30 meters (100 feet), but inrestricted applications the length can be

up to 300 meters (1000 feet). (Pleaseconsult your Triconex Customer Satis-faction representative for assistancewhen configuring a system that exceeds30 meters of I/O bus cable length.)

RXM Chassis are used for systems inwhich the total cable distance betweenthe first chassis and the last chassisexceeds 30 meters (100 feet). EachRXM Chassis houses a set of threeRXM modules in the same position asthe Main Processors in the Main

Chassis. Six remaining logical slots areavailable in an RXM Chassis and oneblank (unused) slot.

On-Line Module Repair

The logical slot arrangement of aTricon chassis provides two ways torepair faulting modules on-line: the hotspare method and on-line modulereplacement.

With the hot spare method, a logical

slot contains two identical I/O modules.

The primary module is active, and theother modulethe hot spareispowered but inactive. The Tricon cycles

control between the two healthy I/Omodules approximately every hour, sothat each undergoes complete diagnos-tics on a regular basis. If a fault isdetected on the primary module, theTricon automatically switches controlto the hot spare module, allowing thesystem to maintain three healthy legscontinuously. The faulty module canthen be removed and replaced.

Alternatively, a module can be replacedon-line even when only one I/O module

is normally installed in a logical slot. Ifa fault occurs, the FAULT indicatorturns on, but the module remains activeon two legs. A replacement module isthen inserted into the unused space inthe slot. The Tricon will grant control tothis second I/O module after it passes adiagnostic test. Once the replacementI/O module becomes active, the faultyI/O module can be removed. This repairmethod demonstrates the Triconsability to automatically transition fromtriplicated to dual control and backagain without process interruption.

A Tricon system should include at leastone hot-spare module in place for eachtype of I/O module in the system. With

this arrangement, the hot spare modulesare tested regularly and can be used foron-line module replacement anywherein the system.

I/O Bus Connections

As shown in the configuration drawingonpage 12, each chassis has three setsof RS-485 I/O Bus Ports (IN & OUT).Additional chassis may branch outfrom the Main Chassis by means of the

I/O Bus Ports, up to a maximum of 14.There are six portstwo sets of threefor triplicated serial communication located on a panel in the upper leftcorner of the backplane. One set ofthree I/O Bus Cables is required foreach Expansion Chassis, and for eachRXM Chassis that houses a PrimaryRXM module set. (Remote RXMChassis are connected to the PrimaryRXM Chassis with fiber-optic cables.)Communication across the I/O BusCables (and the RXM fiber-optic

cables) proceeds at 375 kBaud, thesame rate as the internal I/O bus oneach chassiss backplane.

Chassis Options

A Tricon system is made up of one or

more chassis assemblies which containI/O and communication modules. Thefirst chassis of a system is called theMain Chassis (Model 8110). To enlargea system, Expansion Chassis (Model8111) and/or RXM Chassis (Model8112) can be added. (See SystemConfiguration on page 11for details.)

I/O Expansion Bus

Each chassis has six RS-485 I/O expan-sion bus ports at the top left corner ofthe backplane. There are two sets of

ports for Legs A, B, and C, providingfor two triplicated serial communica-tions paths between chassis. One set ofdrop-line cables is required for eachExpansion Chassis and for the RXMChassis which houses the PrimaryRXM Module set. The standard lengthof a cable set (Model 9000) is 6 feetlonger cables are available if needed.

A 375 Kbaud triplicated I/O bus trans-fers data between the I/O modules andthe Main Processors. A 2 MBaudcommunication bus runs between theMain Processors and the communica-tion modules.

STOP.) The STOP setting is recom-mended for installation and service ofprocess-related equipment, but is notrequired for service of the Tricon.

REMOTEAllows writes to programvariables by TriStation, Modbusmasters and external hosts. (DownloadAll and Download Change by TriSta-tion are not allowed.)

Keyswitch for System Control

The Main Chassis has a four-positionkeyswitch which controls all thechassis in the system. The keyswitchsetting is readable by Tricon and TriS-tation system software, and by applica-tion programs. Switch settings are:

Model 3008 Main Processor (MP)

modules offer improved performanceand greater application memory sizecompared to earlier Tricon MPs.

Three MPs must be installed in theMain Chassis of every Tricon system.Each MP independently communicateswith its I/O subsystem and executes theuser-written application.

Sequence of Events (SOE)

and Time Synchronization

During each scan, the MPs inspectdesignated discrete variables for state

changes known as events. When anevent occurs, the MPs save the vari-ables current state and time stamp inthe buffer of an SOE block.

If multiple Tricon systems areconnected by means of NCMs, theTime Synchronization capabilityensures a consistent time base for effec-tive SOE time-stamping. Seepage 70for more information.

Diagnostics

Extensive diagnostics validate thehealth of each MP, I/O module andcommunication channel. Transientfaults are recorded and masked by thehardware majority-voting circuit.Persistent faults are diagnosed and theerrant module is hot-replaced.

Verify handshake and interruptsignals between the CPU, each I/Ocommunication processor and leg

Check each I/O communicationprocessor and leg microprocessor,ROM, shared memory access andloopback of RS-485 transceivers

Verify the TriClock and TriBusinterfaces

An RS-232 port at the bottom of eachMP is used by Triconex personnel fordiagnostic analysis.

MP diagnostics perform these tasks:

Verify fixed-program memory andstatic RAM

Test all basic processor and floating-point instructions and operatingmodes

Validate user memory by means ofthe TriBus hardware-votingcircuitry

Verify the shared memory interfacewith each I/O communicationprocessor and leg

Enhanced Intelligent

Communication Module

The Model 4119A Enhanced IntelligentCommunication Module (EICM)allows the Tricon to communicate withModbus masters and slaves, TriStationand printers.

For Modbus connections, the EICMuser can select the RS-232 point-to-point interface for one master and oneslave, or the RS-485 interface for onemaster and up to 32 slaves. The RS-485network trunk can be one or twotwisted-pair wires up to a maximum of4,000 feet (1,200 meters).

Each EICM contains four serial portsand one parallel port which can operateconcurrently. Each serial port can beconfigured as a Modbus master with upto seven Modbus masters per Tricon. Asingle Tricon system supports amaximum of two EICMs, which mustreside in one logical slot. (Hot sparingis not available for the EICM.) Eachserial port is uniquely addressed andsupports either the Modbus or TriSta-tion interface. Modbus communication

can be performed in either RTU or

ASCII mode. The parallel port providesa Centronics interface to a printer.

Each EICM supports an aggregate datarate of 57.6 Kbaud (for all four serialports).

Programs for the Tricon use variablenames as identifiers but Modbusdevices use numeric addresses calledaliases. Therefore an alias must beassigned to each Tricon variable namethat will be read by or written to aModbus device. An alias is a five-digitnumber which represents the Modbusmessage type and the address of the

variable in the Tricon. An alias isassigned using the Tricon PointConnections window in TriStation.

Any standard Modbus device cancommunicate with the Tricon throughthe EICM, provided that aliases areassigned to the Tricon variables. Aliasnumbers must also be used when hostcomputers access the Tricon throughother communication modules, such asthe NCM. See Communication Capa-bilities on page 57 for more informa-tion.

Network Communication

Module

With a Model 4329 Network Commu-nication Module (NCM) installed, theTricon can communicate with otherTricons and with external hosts over802.3 networks. The NCM supports anumber of Triconex proprietary proto-cols and applications as well as user-written applications, including thosethat use TCP-IP/UDP-IP protocol.

The NCM provides two BNC connec-tors as ports: NET1 supports Peer-to-Peer and Time Synchronization proto-cols for safety networks comprised ofTricons only. NET2 supports opennetworking to external systems usingTriconex applications such as TriSta-tion, SOE, SER and DDE Server oruser-written applications. SeeCommunication Capabilities onpage 57 for more information aboutTriconex protocols and applications.

Two NCMs can reside in one logicalslot of the Tricon chassis, but they willfunction independently, not as hot

spares. External hosts can read orwrite data only to Tricon variables towhich Alias numbers have beenassigned. (See Enhanced IntelligentCommunication Module on page 26for more information about Aliases.)

The NCM is compatible with theIEEE 802.3 electrical interface andoperates at communication speeds upto 10 Mbaud. The NCM connects withexternal host computers by means ofcoaxial cable (RG58) at typical

distances up to 185 meters (607 feet).Distances up to 4,000 meters (2.5miles) are possible using repeaters andstandard (thick-net or fiber-optic)cabling.

The Main Processors typically refreshdata on the NCM once per scan.

Safety Manager Module

The Model 4409 SMM acts as an inter-

face between a Tricon controller andHoneywells Universal ControlNetwork (UCN), one of three principalnetworks of the TDC 3000 DistributedControl System. Appearing to theHoneywell system as a safety node onthe UCN, the SMM communicatesprocess information at full networkdata rates for use anywhere on the TDC3000. The SMM transmits all Triconaliased data (including system vari-ables) and diagnostic information tooperator workstations in display

formats that are familiar to Honeywelloperators.

The SMM makes the following func-tions available to the TDC 3000:

Handles critical I/O points andpasses results to the DCS

Processes Tricon alarms andpropagates them to user-definedDCS destinations (consoles,printers, etc.)

Reads/writes aliased data to satisfyDCS requests

Reads Tricon diagnostics for displayby the DCS

Write protection to lock out changesto the Tricon safety system from allTDC 3000 sources

Time synchronization from the DCSmaster clock

Hiway Interface Module

The Model 4509 Hiway Interface

Module (HIM) acts as an interfacebetween a Tricon controller andHoneywells TDC 3000 control systemby means of the Hiway Gateway andLocal Control Network (LCN). TheHIM can also interface with Honey-wells older TDC 2000 control systemby means of the Data Hiway.

The HIM enables higher-order deviceson the LCN or Data Hiway, such ascomputers and operator workstations,to communicate with the Tricon. The

HIM allows redundant BNC connec-tions directly to the Data Hiway and hasthe same functional capacity as four

extended Data Hiway Port (DHP)addresses.

The HIM provides eight Hiwayaddresses, implements the same slotstructure as the DHP, and typicallyrefreshes all data in less than 0.5seconds. The hot spare feature allowson-line replacement of a faulty moduleor continuous backup to an activemodule.

RXM Modules

RXM modules and chassis allow I/O

modules to be located several kilome-ters away from the Main Chassis. RXMmodule sets, consisting of three iden-tical modules, serve as repeaters andextenders of the Tricon I/O bus andprovide ground loop isolation. APrimary RXM Module Set supportsthree remote locations by connecting tothree Remote RXM Module Setshoused in remote chassis. See SystemConfiguration on page 11regardingconfigurations that use RXMs.

RXM sets are available for fiber-opticcables with a communication rate of375KBaud. These sets providemaximum immunity against electro-static and electro-magnetic interfer-ence, and support configurations withoptical modems and fiber-optic point-to-point cabling. Remote sites can belocated as far as 7.5 miles (12 kilome-ters) from the primary site.

The figure at right shows uni-direc-tional cabling for three legs of a remotelocation. For each leg, one cable carries

data transmitted from the PrimaryRXM to the Remote RXM, and theother cable carries data received by thePrimary RXM from the Remote RXM.A pair of modules must be wired foreach of the three legs, amounting to atotal of six cables for each remote loca-tion.
