1 Alarm Condition Tool

The Alarm Conditions configuration tool enables you to create local OpenEnterprise alarm conditions.

OpenEnterprise alarm conditions are objects which cause alarms when the conditions are met. For instance, a Tank level which could be dangerous if it gets too high could be configured as an alarm condition. The alarm condition for this would reference the originating object (in this case the specific

Tank's level sensor), and a value for that object which would cause an alarm to be generated.

OpenEnterprise supports remote alarm generation for Bristol RTUs. Local alarm conditions are configured and generated solely within OpenEnterprise, whereas remote alarm conditions are initially configured and generated within the RTU. When the signals are built into the database using the

NW3000 Database Builder, it creates the necessary alarm conditions also, according to the ACCOL or other control language operating within the RTU. When the RTU goes online, any alarms are reported to OpenEnterprise, which generates the alarms in the database. Note that since the NW3000

Database Builder creates alarm conditions for Bristol RTUs during the database build process, the

Alarm Condition Configuration Tool should not be used to create or modify remote alarm conditions for Bristol RTUs.

1.1 Alarm Condition Tables

To create an alarm for a signal or any object, it must be referenced by an alarm condition object in one of the Alarm Condition tables provided within the OpenEnterprise database.

The name of the Alarm Condition table provides a clue to the signal or object types on which the alarm condition should be applied. For instance, the realanaloglimitalarmcondition table enables you to create alarms for any realanalog signal based on six value limits (low range, lowlow, low, high, highhigh and high range).

1.2 Alarm Condition Configuration

All Alarm Condition Configuration, including the selection of the Alarm Condition Table is done from the main Alarm Condition Configuration Dialog, which opens when the Alarm Conditions Tool is selected from the Toolbox.

1.3 Alarm Condition Elements

An alarm condition must have the following properties defined: -

1. A unique id.

2. An object to which it relates (e.g. a signal).

3. An alarm condition type (e.g. high, change of state). Alarm Condition type codes and their explanation are stored in the Alarm Condition Lookup table.

4. For certain types of alarm, a user defined value or range of values which causes the alarm condition to raise an alarm (e.g. 75, 95, Bit 0, 1-7)

1.4 Alarm Condition Lookup Table

The AlarmConditionLookup table contains the ID number and description of all available alarm condition types. Each alarm condition object must have an alarm condition type. Below is a list, showing the alarm condition type's ID number, it's description and the tables using that alarm condition type.

2 Alarm Condition Tables

The table names shown below are the Alarm Condition tables as displayed within the Alarm Condition drop-down list on the Alarm Condition Tool's Main Dialog. All are derived from the AlarmCondition table.

Each of the alarm condition tables can contain one or more actual alarm conditions. Each alarm condition relates to a single signal. Many alarm conditions also require a specific value that raises the alarm, although some, like the integer and realanalogchangevalue alarm conditions raise an alarm if the signal's value just changes.

The type of the alarm conditions stored in each table is indicated by the name of the table. Most alarm condition tables contain one alarm condition type, but others may contain more than one alarm condition type. For instance, the realanaloglimitalarmcondition table can contain 6 alarm condition types (High Range, HiHi, Hi, Lo, LoLo and Low Range). A list of available alarm types is stored in the

Alarm Condition Lookup table. abdevicehealthalarmcondition alarminhibitalarmcondition alarminhibitstatealarmcondition calculationstatusalarmcondition digitalalarmcondition digitalchangetonullalarmcondition digitaldelayalarmcondition digitalstatealarmcondition integeranalogalarmcondition integeranalogchangetonullalarmcondition integeranalogchangevaluealarmcondition integeranalogdeviationalarmcondition integeranalogequalsalarmcondition integeranaloglimitalarmcondition integeranalograteofchangealarmcondition integeranalogsignalalarmcondition journalalarmcondition journalequalalarmcondition journalrangealarmcondition multistatedigitalalarmcondition notesalarmcondition nw3000devicecommunicationalarmcondition nw3000devicestatusalarmcondition nw3000deviceversionalarmcondition nw3000digitalalarmcondition nw3000questionablealarmcondition nw3000realanalogalarmcondition oeprinteralarmcondition oeprintergroupalarmcondition questionablealarmcondition questionableequalsalarmcondition questionablerangealarmcondition realanalogalarmcondition realanalogchangetonullalarmcondition realanalogchangeofvaluealarmcondition realanalogdeviationalarmcondition realanalogequalsalarmcondition realanaloglimitalarmcondition realanalograteofchangealarmcondition realanalogsignalalarmcondition redundancyalarmconditiona redundancyalarmconditionb reportequalsalarmcondition reportrangealarmcondition runsqlscripterroralarmcondition rocpointalarmcondition triggersqlprocedurealarmcondition

3.2 Filter Grid Entry

The Filter Grid section enables the user to filter the Conditions List by any attribute in the selected

Alarm Condition table. When the [Refresh] button is selected, the Alarm Condition List will be refreshed according to the filters applied here. For a detailed description of how to use wildcards and filter for special characters within the filter grid, see the Filtering with Wildcards topic.

3.3 Filtering with Wildcards

The filter grid allows use of wildcard characters, character lists, or character ranges, in any combination, to match strings.

The following table shows the characters allowed in patterns and what they match:

Character(s) in pattern Matches in string

?

*

#

[charlist]

[!charlist]

Any single character.

Zero or more characters.

Any single digit (0 - 9).

Any single character in charlist.

Any single character not in charlist.

A group of one or more characters (charlist) enclosed in brackets ([ ]) can be used to match any single character in string and can include almost any character code, including digits.

Note: The special characters left bracket ([), question mark (?), number sign (#), and asterisk (*) can be used to match themselves directly only by enclosing them in brackets. The right bracket (]) can't be used within a group to match itself, but it can be used outside a group as an individual character.

In addition to a simple list of characters enclosed in brackets, charlist can specify a range of characters by using a hyphen (-) to separate the upper and lower bounds of the range. For example,

[A-Z] in a pattern results in a match if the corresponding character position in string contains any of the uppercase letters in the range A through Z. Multiple ranges are included within the brackets without any delimiters.

The meaning of a specified range depends on the character ordering valid at run time (as determined by the locale setting of the system the code is running on). The range [A - E] matches A, a, À, à, B, b,

E, e. Note that it does not match Ê or ê because accented characters fall after unaccented characters in the sort order.

Other important rules for pattern matching include the following:

• An exclamation point (!) at the beginning of charlist means that a match is made if any character except the ones in charlist is found in the string. When used outside brackets, the exclamation point matches itself.

• The hyphen (-) can appear either at the beginning (after an exclamation point if one is used) or at the end of charlist to match itself. In any other location, the hyphen is used to identify a range of characters.

• When a range of characters is specified, they must appear in ascending sort order (from lowest to highest). [A-Z] is a valid pattern, but [Z-A] is not.

4 Add/Modify Alarm Condition

The example below shows the Add/Modify Alarm Condition Dialog as it would appear if the realanaloglimitalarmcondition table had been selected. If another alarm condition table had been chosen, the dialog could look slightly different, for example, see the Questionable Mask page.

Typically, all fields and buttons from Priority down to Signal will be the same, whatever Alarm

Condition table has been selected.

For an outline of special user input required for other types of alarm conditions, select the alarm condition table from the Alarm Condition Tables topic.

4.1 Priority

Selection of this mandatory field will display a drop-down list of alarm priorities. The user should select the correct description for the priority which is being added. The field value defaults to Alarm

Priority #0.

4.2 Precedence

This mandatory field represents an overall level of importance for an alarm condition that is applied to a particular signal. It is particularly helpful when there are a number of alarm conditions attached to a signal. For instance there may be a Low and LowLow condition on a Tank Level. If the signal changes from Normal to LowLow, a Low alarm will also be generated during the signal transition.

The precedence attribute will distinguish between these conditions so that the condition with the highest Precedence will be displayed as the Current State of the Signal. You must type a valid integer into this field if it is to be effective, otherwise the value will default to 0 (the lowest precedence). A high number equals high Precedence, a low number equals a low Precedence. Numbers may range between 0 and 999,999,999.

4.15.2 Play Sound Number of Times

Defines the number of times that the .WAV file should be played. A value of &endash;1 will indicate that the file should be played infinitely, and 0 that the file should not be played. Values between

&endash;1 and 9999 will be allowed.

4.15.3 Sound Configuration Example

To assist with an understanding of how sound files are played, the following example is provided. The names used refer to files with a .WAV extension.

The Default Alarm Priority Sound Configuration for priority 0 alarms is to play, &rdquor;Low Priority

Alarm Requires Attention”, For priority 1 alarms the default is to play, &rdquor;High Priority Alarm

Requires Attention”.

Priority 1 alarms have higher precedence than priority 0 alarms.

A Priority 0 alarm is reported to a previously empty Alarm Client instance, which has it’s own sound configuration defined to play &rdquor;Low Tank level on Tank 3” five times. A second Priority 0 alarm is reported after the first Priority 0 alarm has been played once. It is configured to play

&rdquor;Abnormal Flow in Pipe X35” five times.

&rdquor;Low Tank Level on Tank 3” has played four times, when a Priority 1 alarm is reported with it’s own sound configuration defined to play &rdquor;Boiler 2’s Pressure Has Exceeded Safe Limits” three times. After this has been played twice a second priority 1 alarm is reported. It is defined to play

&rdquor;Explosion Imminent Clear Building” continually until it is acknowledged.

This alarm is eventually acknowledged, but not until the first priority 1 alarm has played its .WAV file the requisite number of times. The original Priority 1 alarm is acknowledged also, followed finally by the two Priority 0 alarms.

This is what the operator would have heard&ldots;

[Priority 0 Alarm Reported]

&rdquor;Low Tank Level on Tank 3”


[Second Priority 0 Alarm Reported]

&rdquor;Abnormal Flow in Pipe X35”




[Priority 1 Alarm Reported]



Reference Guide

[Second Priority 1 Alarm Acknowledged]

&rdquor;High Priority Alarm Requires Attention”

&rdquor;High Priority Alarm Requires Attention”

[First Priority 1 Alarm Acknowledged]





[Both Priority 0 Alarms Are Acknowledged]

Note that because the .WAV files associated with the Priority 0 alarms were not played the requisite number of times (i.e. 5) before the first Priority 1 alarm came in, they are therefore replayed once the

Priority 1 alarms have been acknowledged. If they had been played the requisite number of times, then once the Priority 1 alarms had been acknowledged, the Default Alarm Priority Sound

Configuration for Priority 0 alarms, i.e. &rdquor;Low Priority Alarm Requires Attention”, would have been played instead.

If the 'Prompt for Filter Before Querying Database' box is checked, then when a new filter is applied to the Browse for Signal dialog a message at the top of the Signal List will prompt the user to press the

[Refresh] button before the new query is sent.

4.16.4.2 Browse for Signal Number of Objects

The number typed into this field determines the maximum number of objects that will be returned and displayed in the Signal List each time a new filter is added to the Filter Grid and the [Refresh] button is selected.

4.16.5 Signal List

This pane displays the signals returned by the query based on the filter supplied in the Filter Grid. The number of signals displayed per query is determined by the number of objects to retrieve value, which is set on the Options dialog.

4.16.6 Browse for Signal Next Button

When this button is selected the next batch of signals matching the filter in the Filter Grid will be returned and displayed in the Signal List. The number defaults to 100, but may be changed using the

[Options] button.

4.16.7 Browse for Signal OK Button

When a signal has been selected from the Signal List, selecting the [OK] button will enter the signal name into the signal field on the main Alarm Condition dialog and the Browse for Signal dialog will close.

Local Alarms: Alarms that are configured using the Alarm Condition Tool. These alarms are generated by OpenEnterprise.

R

Remote Alarms: Alarms that are configured and generated within the RTU. OpenEnterprise supports remote alarms for Bristol Babcock RTUs. The NW3000 Database Builder enters remote alarm conditions configured within Bristol Babcock RTUs into the database during the database build process. These alarms are initially generated at the RTU, and reported to

OpenEnterprise. OpenEnterprise then generates the alarms.
