Figure 1 TotalPlantSolution (TPS) Architecture with Application Module

Introduction

This publication defines thesignificant functions of theTotalPlantSolution (TPS)Application Module.

The Application Module is one ofthe modules on the Local ControlNetwork (LCN). As Figure 1indicates, it communicates withother modules on the same orother Local Control Networks andwith process-connected deviceson the Universal ControlNetworks and Data Hiways.Because of its position in thesystem architecture, theApplication Module can acceptinputs from multiple process-connected devices, as well as

from other modules on thedifferent Local Control Networks.It can also provide control outputsto control elements in theprocess or to other data points inmodules on the different LocalControl Networks, including itself.For more information on the role

of the Application Module in theTPS system, refer to the SystemTechnical Data.

With at least one ApplicationModule present in a TPSsystem,more advanced calculations andcontrol strategies can beimplemented. Each ApplicationModule data point can havemultiple inputs and outputs frommany devices, and a singleApplication Module can handlemany more data points than a

single process-connected box.The Application Module featuresa full complement of controlalgorithms. The ControlLanguage that executes in theApplication Module makes it easyto develop custom pointprocessing and special

algorithms. The ApplicationModule provides full cascadefunctionality between an AMpoint and any process data pointresident in modules on differentLCNs.

Functional Description

The relationships of the majorfunctions of the ApplicationModule are shown in Figure 2.

Data Points

The Application Module containsa process database made up ofdata points that the processengineer builds and assigns to it

during configuration. Each datapoint is a collection of fixed anddynamic parameters that performsa specific function and isidentified by a point name. Data-point processing can use eitherpreprogrammed or customalgorithms to calculate requiredinformation and/or initiate specificcontrol action.

In addition to regulatory datapoints that represent continuousvariables in or related to the

process, the Application Modulealso offers several utility data-point types. These include thefollowing:

Timersprovide timingfunctions.

Countersprocess counterinputs.

Flagsboolean variables.

Numericnumeric variables.

During configuration, the user

defines the data-point name,point type, selected algorithms (ifapplicable), input sources (up to16, from multiple sources), outputdestinations (up to 8), alarm trippoints, and the processingschedule. Other informationpertinent to the type of data pointmay also be entered, or standarddefault values may be used.

Data Point Scheduling

Each data point in an ApplicationModule is processed according toa schedule defined by theprocess engineer duringconfiguration. The engineer mayassign a data point to a "fast"processor, a "slow" processor, oran internetwork point processor,and may choose from a variety oftime intervals from 1 second to 24hours. The fast processor has ahigher priority, so data pointsassigned to it are processed atmore regular intervals. Generally,

noncritical, low-frequency datapoints are assigned to the slowprocessor, so that they do notinterfere with the processing ofdata points assigned to the fast

processor. The internetworkpoint processor provides forclosed loop control across theNetwork Gateway.

The user can also schedule datapoints to be processed before orafter another data point, ondemand, or when some user-defined process event occurs.When a regulatory data point in anApplication Module is processed,it goes through most or all of thesteps in the sequence shown in

Figure 3.

Regulatory Control

General Input ProcessingAt theuser's option, a regulatory datapoint can fetch values from theprocess database and updatedesignated parameters within thedata point before proceeding withthe remainder of its processing.

PV Processing A regulatorydata point that uses PVprocessing fetches thedesignated PV inputs from aprocess-connected box or

module on the Local ControlNetwork before executing thespecified PV algorithm (see Table1), or custom algorithm (see the"Custom Control" description

below). The PV is calculated,checks are made to determine iflimits have been violated, and avalue status (good, bad, oruncertain) is assigned.

Control Processing Aregulatory data point that usescontrol processing obtains thedesignated control inputs fromPV processing, or elsewhere,before executing the selectedcontrol algorithm (see Table 2), orcustom algorithm (see "CustomControl"). When configured to doso, such a data point can also

store the output in other datapoints in the same or anotherApplication Module or in someother LCN-based module orprocess-connected device.Multiloop control schemes arenormally configured to providebumpless transfers from onemode of operation to another.

Control Output ProcessingControl output processingstores a whole value appropriateto the units of the destinationparameter. It also accommodatesany control constraints, including

any output high/low limits, outputincrement limits, and integralhigh/low limits, as well as handlinginitialization, mode change, andantiwindup conditions.

Alarming Alarms for regulatorydata points can be selected bythe user from the types ofconditions listed below. If analarm is detected as a data point isprocessed, that event is

journaled, annunciated, anddisplayed in the same way as analarm detected by a process-connected device.

Custom Control

In addition to the built-in PV andcontrol algorithms, the engineermay use the Control Language(CL/AM) to define his ownalgorithms and processingroutines. Control Language canbe written at a TPS UniversalStation/Universal Work Station, orat a personal computer using anoptional software package calledWorkbook, that runs under MS-

DOS/PC-DOS. Programs arecompiled at a Universal Station orUniversal Work Station. ControlLanguage algorithms androutines are inserted at specifiedpoints in the Application Moduleprocessing order.

Control Language ControlLanguage is designed specificallyfor the Process Engineer to usein implementing custom controlschemes. This easy-to-uselanguage employs a variety of

general and process-orientedstatements (see Table 3 andFigure 4) and provides asignificant improvement in bothsecurity and throughput overprevious customizationtechniques.

Security features include checksto make sure that parameters andstorage destinations are valid,and to protect against user-codedinfinite loops.

Custom Data SegmentsCustom Data Segments (CDS)are parts of a data point used forstoring data that is to be used byControl Language programs. Forexample, the name of eachparameter and its type, units, andchange authority are includedwhen the segment is defined.Once defined, and attached tospecific data points, the customsegment data is automatically

BLOCK dual_oxy (point CAI1515;& at pv alg)

This block of CL code selects the higher of two recycle oxygen readings from

dual oxygen analyzers and places that value as the PV of point CAI1515. Ifone of the analyzers is off scale, out of limits, or out of service, theother analyzer is selected. Also, if one of the analyzers is bad or out ofservice, the PV source for another loop in the control scheme is set toMANUAL.

Figure 4 Sample Control Language Program

Execution of a block might betriggered by a specific event,such as crossing an alarmthreshold or when it becomesnecessary to initialize a controlloop.

Background CL programs areattached to a data point andexecute whenever CPU time isavailable. Consequentlybackground routines do not slow

down point processingexecution.

Control Language Algorithms The standard sets of both PV andcontrol algorithms have "ControlLanguage algorithm" as one ofthe choices, making it easy for theuser to substitute his ownalgorithm in the standard point-processing scheme.

Custom Multipoint SwitchStrategies A Control Languageswitch data point can be usedwith user-written ControlLanguage routines to monitorand direct control of strategiesthat involve different sets of datapoints. The multipoint ControlLanguage routines respond tostrategy changes requested bythe process operator through aUniversal Station.

Physical Description

When packaged as a 5-cardmodule, the Application Modulecontains a Local Control NetworkInterface board,microprocessor/memory board(s),a power supply, and a fanassembly. If the AM is a memberof a redundant pair, there is also a

redundancy board. The dualnode version of the ApplicationModule contains a high-densityK2LCN board, a power supply,and fan assembly. The boardsand power supply are OptimumReplaceable Units** formaintenance.

Both types of electronicsmodules mount in a standard 19(48 cm) RETMA rack and aretypically mounted in a standardTPS system cabinet.

The Local Control Networkconnects to the module throughcoaxial connectors.

** Optimum Replaceable Units(ORUs) are replaceableassemblies that provide the besttrade-off between the cost of theORU and the cost of attempting toisolate troubles to a smaller partof that ORU. Examples of ORUsinclude printed-circuit boards,power supplies, printers, andWinchester disk drives.
