1 IntroductionThe CLT (Custom Logic Tool) provides the user with an opportunity to develop additional logic functionality for the

ADVC Controller Range. By evaluating user-defined collections of Digital and Analogue data points from theexisting Protocol Database, the CLT is used to alert operators of specific conditions that may exist on site. Basedon these conditions it is also possible to perform basic actions automatically if required.WSOS5 incorporates the newly developed CLT user interface that is used to create the custom logic expressions.

In addition to CLT, WSOS5 also incorporates other customisation tools that are used to manage CommunicationProtocols, Operator Interface and Input/Output devices. Each of these tools operates independently, provides theuser access to the Protocol Database points and offers a limited level of logic functionality. CLT significantlyenhances the logic capabilities of all these tools by providing additional Protocol Database points. These newpoints can be incorporated in the existing configuration of these tools. (Please see chapter 7)The CL T incorporates the following functionality:

Custom Digitals Design your own logic functions to provide True/False state indication and executeactions based on the result of logic expressions.

Custom Variables Preset variable values used in logic expressions. Modify the active values via protocolto easily adapt the custom logic functionality to different conditions or applications.

Custom Counters Create counters to monitor the number of transitions in logic expressions. The countervalues are available via protocol and are used in the custom logic functions. (Underdevelopment)

Custom Timers Create timers to monitor the duration of transitions in a logic expression.

The subsequent chapters describe the CLT operator interface and the functionality of the different elements. Theyalso contains some practical examples.

1.1 Compatibility ADVC Controller firmware A45-03.00+WSOS 5 version: Version 5.13.01+Switchgear: N-Series, U-Series, W-Series, RL-SeriesFunctionality: ACR (Automatic Circuit Recloser), LBS (Automatic Sectionaliser).

1.2 RatingsThese timing results are from tests performed over different controller conditions like loading CPU to max, allprotection elements pickup etc. In normal usage timing values will be less.Response time for logic functions 2.3 secondsResponse time for analogue functions 3.2 secondsResponse time for timer functions 2.1 secondsExpression size limitation 255 elements

WARNINGUNEXPECTED EQUIPMENT OPERATION

The designer of any logic or control function must consider the potential failure modes of the logic or controlfunctions and provide a means to achieve a safe state during, and after a failure.Examples of critical control functions are Work Tag, Hot Line Tag, Trip and Close operations.

Separate safety procedures must be provided for critical control functions. Consideration must be given to the implications of logic functionality, anticipated response times and system

operating characteristics. Each implementation of a Custom Logic Map must be individually and thoroughly tested for proper operation

before being placed into service.

Failure to follow these instructions can result in unexpected operation and associatedattendant hazards.

4.5 Custom Digitals4.5.1 About Custom DigitalsWith Custom Digitals you create your own logic functionality. The logic functionality is used to provide the local orremote operator with unique True/False state indication. It is also possible to associate commands with the logicfunctions, therefore executing actions based on the logic expressions.

Figure 5: Custom Digitals flow diagram

Based on information contained in the protocol database, Custom Digitals provide two main functions: Create additional status data in the database, making the results available to other database-related tools Perform basic automation through actions linked to custom digital points.

Example 1. Switchgear StatusThis example illustrates the use of digital database points and operands such as AND, OR and NOT.Use Digital 01 to create a logic point to assist an operator during a site visit in verifying that the switchgear is in thecorrect status before leaving the installation. For this example the correct switchgear status is when:

the switchgear is closed, protection group A is active,

the Work Tag is removed, the Auxiliary supply fail, and the battery supply fail.

The protocol database includes status points that can be used to achieve this functionality. These are:Database point True when False whenSwitchgear Closed Switchgear closed Switchgear not closedProtection Group A Active Protection Group A is active Protection Group A is not activeWork/Hot Line Tag Work (Hot Line) Tag applied Work (Hot Line) Tag removedAuxiliary Supply Fail Auxiliary supply fail Auxiliary supply normalBattery Supply Fail Battery supply is not normal Battery supply is normalMaintenance Required Maintenance needed Maintenance not required

The green cells highlight the states that will provide the necessary indication. Using Boolean algebra to satisfy therequirement, the configuration for Custom Digital Point 01 in the Digitals Worksheet will be:Name Change Custom Digital 01 to Confirm Switch Status.SetExpression

Switchgear Closed AND Protection Group A Active AND (NOT( Work/Hot Line Tag OR AuxiliarySupply Fail OR Battery Supply Fail ))

ResetExpression

The Reset Expression is optional. Confirm Switch Status will become False when the SetExpression evaluates to False. Alternative it is possible to create a reset expression containing thesame or different database points. As an example it can include an additional check for possiblemaintenance required.NOT ( Switchgear Closed AND Protection Group A Active ) OR Work/Hot Line Tag OR AuxiliarySupply Fail OR Battery Supply Fail OR Maintenance Required

Example 2. Low Battery TripThis example illustrates the use of analogue database points with operands such as and , and the use ofset/reset actions.Use Digital 02 to create a battery monitoring function that will trip the switchgear when the battery voltage fallsbelow a predetermined level of 21.6V. When the battery voltage recovers to above 22.6V normal operation must bepossible.The protocol database includes an analogue Battery Voltage point that will be used to achieve this functionality. Italso requires an action to trip the switchgear.Analogue Database point DescriptionBattery Voltage Analogue database point

Minimum value is 0, Maximum value is 32Volts,Resolution is 0.01 and Deadband is 1

Database control point DescriptionTrip Switchgear and block When this point is asserted, the switchgear will trip. Simultaneously closeoperations from any source are blocked. The block is removed by turningthe point off.

In the Digitals Worksheet configure point 02 to the following.Name Change Custom Logic 02 to Low Battery Trip.SetExpression

Battery Voltage 21.6V

ResetExpression

Battery Voltage 22.6V

Set Action ON Trip Switchgear and blockReset

ActionOFF Trip Switchgear and block

Note how the above expressions use different voltage levels to create a deadband. It is also important to note thatthe reset expression is used to remove the close block. However it does not close the switchgear. An operator hasto close the switchgear manually.

4.6 Custom Variables4.6.1 About Custom VariablesCustom Variables is a collection of preset values. The preset values are used as active values in logic expressionscontaining analogue database points. It is possible to override the active values via protocol. This flexibility allows astandard map to be created and loaded to a collection of switchgear devices. Each device can be calibrated tothe different conditions or applications via protocol without altering the standard map.

Figure 7: Custom Variables flow diagram

The purpose of the Custom Variables is to: Provide a selection of preset values that is available to all logic expressions containing analogue database

points. Provide remote access to the variable values in order to adapt the functionality of the custom logic map to

different conditions.

4.7 Custom Counters4.7.1 About Custom CountersCustom Counters determine the number of times a particular logic status has occurred. The counter values canchange in either direction (Count Up or Down), under the control of separate Increment/Decrement logicexpressions. The active values of the counters are available via the protocol database for remote display. Activevalues can also be incorporated in logic expressions to drive logic functions, indication and even automationactions.

Figure 9: Custom Counters flow diagram

The custom counters provide two main functions: Count (up or down) logic transitions with the counter value available via protocol for remote indication Counter values are used as analogue database points in logic expressions.

4.8 Custom Timers4.8.1 About Custom TimersCustom Timers are available to filter or delay transitions in logic expressions. Each timer has a preset duration, andstarts running when the Start/Stop Expression evaluates true. When the timer expires a logic output is asserted.The output remains asserted until the Reset Expression evaluates true. There are three different types of timers tochoose from. Each responds differently to the start/stop logic expression. Their behaviour can be summarised asfollows:

Type CharacteristicsDe-bounce Timer If the Start/Stop Expression evaluates true, the timer starts running. However, if the

Start/Stop Expression becomes false before the timer expires, the timer resets to thepreset value. Therefore, the timer output is only asserted if the Start/Stop Expressionremains in a true state for a period greater than the preset value. The output is assertedwhen the timer expires.

Cumulative Timer If the Start/Stop Expression evaluates true, the timer starts running. The timer ispaused if the Start/Stop Expression becomes false before the timer has expired andcontinues when the expression becomes true again. Therefore, the timer output isasserted when the combined duration of true state equals the preset value.

Latching Timer If the Start/Stop Expression becomes true, regardless of the duration, the timer outputis asserted a time equalling the preset value after the initial transition to the true state.

The timing diagram below compares the different types of timers using the same Start/Stop Expression and timescale.

Figure 11: Timer comparison

The custom timers provide three main functions: Filter transitions in logic expressions to act only on those exceeding a preset duration. Measure the cumulative duration of a logic state. Delay the transition in a logic expression by a preset time.

Custom timers are used in conjunction with the other CLT functions.

5 Logic expressions5.1 Logic Expression Builder interface

5.1.1 IntroductionThe Logic Expression Builder is used to add points and operands tothe expression field in the Custom Logic Tool Worksheet interface.It is used to create two different types of logic expressions:

Logic expressions and Action expressions.

The Builder accessed from the Custom Logic Tool Worksheets byselecting the f x symbol. Figure 14 shows the typical expressionbuilder window comprising five main components. Thesecomponents are discussed in subsequent paragraphs. Availability ofthe first three components located on top depends on the type oflogic expression being created. The table below summarises theavailability.

5.1.3 Point Values ToolboxPoint Values are used to control the action of digital control points.This toolbox is only visible when creating action expressions.

ON Turns the control point ON.OFF Turns the control point OFF.

TOGGLEToggles the state of the control point. If itwas in the ON state the point is turned offand vice versa.

Figure 16: Point values toolbox

5.1.4 Formatting ToolboxThe formatting tools are used to alter the appearance of theexpressions in the expression window.

INDENT indents the current line in the expressionwindow. This tool is not available when actions are beingcreated.NEW LINE inserts a new line in the expressionwindow. This tool is not available when actions are beingcreated.DELETE ALL TEXT deletes the contents of theexpression window.

Figure 17: Formatting toolbox

5.1.5 Data Points windowThe data points available in the specified firmware version aredisplayed in the Data Points window. It is important to know thatthere are two main groups of data points available:

Status Data Points (used as inputs in logic expressions)

Control Data Points (used to cause specific actions).There are two different types of status data points:

Logic (True/False) Analogue.

All the control data points are Logic (On/Off).Logic points have a symbol to identify the digital nature. Agroup of logic points are identified by the symbol.

Analogue points have a symbol to identify the analogue nature. A group of analogue points are identified by the symbol.The Find feature is used to search the text names of the databasepoints and it will only display those points containing the text typedinto the Find field.

All database points are contained in a three-tier structure. The +symbol is used to browse to the different tiers. Simply click on the+ to display the contents of the group.

Figure 18: Data Points window

5.1.6 Filter Data PointsThe Version Filter reduces the set of database points to only thoseavailable in the specified range of firmware.

Figure 19: Filter data points

5.2 OperandsSeventeen operands are provided to describe the relationship between database points in logic expressions. Thisparagraph describes the function of the different operands and illustrates its use with logic and analogue datapoints. There are three groups of operand:

Logic Operands used with logic database points Analogue Operands used with analogue database points Mathematical Operands used to perform calculations on set values.


24/36


5.2.1 Logic OperandsLogic operands are used with logic database points. AND , OR , NOT and XOR are logic operands used toimplement Boolean functions. It performs a logic operation on one or more logic inputs and produces a single logicoutput. The table below summarises the function of the logic operands by showing the output of the differentoperands for the same inputs. A and B are digital database points.

Database points Result of expressionA B NOT A NOT B A AND B A OR B A XOR B 0 0 1 1 0 0 00 1 1 0 0 1 11 0 0 1 0 1 11 1 0 0 1 1 0

Operand DescriptionNOT When the database point is true, the result is false.AND If all the database points are true, the result is true.OR If one or more of the database points are true, the result is true.XOR The result is true if the database points are not equal.

It is possible to simultaneously use different combinations of logic operands in one expression. Example: A AND B AND C

A OR B OR C (A AND B) OR C NOT( A AND B AND C) (A XOR B) OR C

5.2.2 Analogue OperandsThe analogue operands ( =, , andStore Number ) are used with analoguedatabase points. To illustrate the function anddifference between the operands, Figure 20 shows the behaviour of the differentoperands when applied to the same counterdatabase point. The counter counts up over aperiod of time and when used with each ofthe operands and a specific set value, willdeliver the results as shown.Store Number is used to add a fixed setvalue in the expression.For example:To create an expression where a counterpoint such as Operations Counter is greaterthan 1000, the following steps are required:1. Find the Operations counter database

point in the expression builder.2. Add the point by double clicking on the

point name.3. Select high alarm as the analogue

logging option.4. Select the operand > to add it to the

expresion.5. Select the operand Store Number and

enter the number 1000 when prompted.The expression will look something like this:Operations Counter > 1000

6 Loading CLT maps to the controllerMake the custom logic tool available in the switchgear file. TheCustom Logic Tool Available field is found under the General sectionof the Feature Selection Window in WSOS.

When CLT is available in the switchgear a new option is added tothe switchgear explorer to access the Custom Logic Tool.Selecting the Custom Logic Tool option opens the window below.

Click on the CLR Description field to select the map for theswitchgear.

The adjacent window allows the user to select the Custom LogicTool Map from a list of *.clt files that exists on the personalcomputer. Select the file and click OK.

This attaches the CLT map to the switchgear file. Save theswitchgear file and go online with the switchgear. In the OptionsMenu select Write Switchgear Settings to Switchgear, select theCLT Mapping option and follow the onscreen instructions to load themap to the controller.

The Operator interface includes a field to display the name of the map in use. For the setVUE operator interface aCustom Logic page displays the Map name being used. In the flexVUE operator interface Engineering menu >Configuration menu > Custom Logic Menu the Custom Logic Map displays map name of the file being used.Both these pages are not visible when CLT feature is disabled from WSOS.

7 Integrating custom logic pointsCLT provides a variety of Operands to describe the relationship between the selected database points in a Logic

Expression. The results of the logic expressions are available via the Protocol Database to the CPMT, OCP andIOEX tools, significantly enhancing the status reporting via communications protocol, operator interface andinput/output devices.Figure 24 below demonstrates the relationship between the different customisation tools. Note how all the mapsare created separately based on the data contained in the protocol database. Each tool has its own operator guide.This guide focuses on the Custom Logic Tool (CLT).Note: This document often refers to a map for the different tools. Example CPMT map, OCP map, IOEX map,CLT map. In this context map refers to the file containing the logic expressions, input and output characteristicsand relations.

8 Event log entries

The custom digital points are logged in the event log when the state of the point changes. The source for theseevents is CLT for Custom Logic Tool. The event log entry is of the format:Timestamp Logic point name ON/OFF

Example: Timestamp Custom logic 01 ONWhen the user enables logging of the maximum/minimum values in logic expressions containing analoguedatabase points the event log entries are:Example: Timestamp1 High Power Alarm ON

Timestamp2 High Power Alarm Max ValueTimestamp2 At time Max timeTimestamp2 High Power Alarm OFF

In the above example High Power Alarm is the alias set by the user and ON when the point is asserted.

Timestamp1 is when the alarm was turned ON. Timestamp2 is the time when the alarm was turned off. At thistimestamp three events are recorded. The first reports the maximum value, the second the time at which thismaximum was recorded and the third reports that the logic point was turned off. Max Value is the maximum value.When an action is linked to a virtual point, the event log will show the virtual point entry as described above plusthose events associated with the action. Example if the High Power Alarm virtual point above had associated withit the action to change the active protection to Protection Group C, the event log entries in WSOS would looksomething like this:Timestamp CLT High Power Alarm ONTimestamp CLT Protection Group (C) RequestedTimestamp Protection Group C ActiveThe source is shown in the event log when it is viewed on the flexVUE or setVUE operator interfaces.The event log can be filtered to only display CLT related events.

9.2 Two Stage Low battery alarmThe two stage low battery alarm is used to detect when the battery capacity is depleted. And when the determinedlow voltage level is detected, the controller trips the attached switchgear. After the trip action the controller shutsdown due to the low power condition. If preferred the map can be modified to raise an alarm via protocol ratherthan trip the switchgear.
