Pipes Configuration Category

The Pipes Configuration Category is divided into five sub-categories:

Settings Sub-Category

The fields in this application pane are used to set up the configuration properties of pipes.

The application pane is divided into the following sections.

Settings Section

If pipe connection size data is to be output when synchronising, make sure that the Pipe Size Connection Output checkbox is checked.

Also, if the Pipe Size Connection Output checkbox is checked, the process owners of components on pipes will be recorded (e.g. in AVEVA P&ID Reports) as the pipe segments to which they belong. If it is not checked, the process owners of components on pipes will be recorded as the main pipes they belong to, instead of one of its segments.

If the process links are to be drawn in default styles specified in this section, select the Set Default Pipe Style checkbox. This enables the rest of the fields and checkboxes in this section:

• Select the default style of process links in the Default Process Link Style field.

• Select the default style of instrument process links (also known as "Legacy" process links) in the Default Instrument Process Link Style field.

• If the sizes of process links are to be restricted to a maximum size, and a default size specified for them, select the Set Process Link Filter Sizes checkbox.

• Then select the maximum size for process links from Maximum Allowable Size for Process Links list. The list consists of the content of the Metric Sizes or Imperial Sizes list of values (refer to List of Values Configuration Category), depending on the project type (metric or imperial).

• Select the default size for process links from Default Size for Process Links list. The list of values available is the same for that available for the Maximum Allowable Size for Process Links setting, except that it only goes up to the maximum size specified by that setting.

  Note: When process links are drawn, they will be drawn at the default size, unless the main pipe they are connected to is smaller, in which case they will be set to that size instead.

Breaks Section

This section contains the following settings:

• The Automatic Breaks ON checkbox governs whether pipes break automatically or not when crossed by another pipe. If the checkbox is not checked, warnings are given that junctions have not been formed when pipes cross each other. If the checkbox is checked, pipelines drawn crossing other pipes will be drawn with breaks positioned according to the setting of the Break Pipe Direction field.

• If a symbol is to be used to depict pipe breaks, for example, instead of pipe breaks being depicted by a gap, check the Use Symbol as Break Line ON checkbox The adjacent drop-down list is used to select the required symbol.

  If pipe breaks are to be depicted by a gap, with a symbol on either side of the gap, leave the checkbox unchecked, and complete the settings.

  Note: If the Use Symbol as Break Line ON checkbox is checked, the settings below are disabled.

• The Break Distance field is used to set the width of the gap created in the pipe when it is broken by another. This distance separates the break symbols.

• Depending on which Break Pipe Direction button is selected, Horizontal and Vertical, pipes will either break vertically or horizontally, assuming the Automatic Breaks ON checkbox has been checked.

• The Symbol Name field is used to specify the break symbol inserted when a pipe is broken, e.g. LBRK. The symbol name is selected from a drop down list.

• The Symbol Layer field is used to specify the layer on which the break symbols reside. The layer name is selected from a drop down list.

• The Symbol Colour field defines the colour of the break symbol inserted when a pipe is broken.

  The Browse button adjacent to the Symbol Colour field is used to select the colour. On selection of the button, the colour selection dialog box is displayed:

  

  The Colour Code can be selected using the following methods:

  • Selection of one of the colours shown in the palette

  • By double clicking the Assume Owner Colour hyperlink. Items will automatically assume the colours of the owning items, e.g., the colours of the lines they are inserted into. When there is no owning item, they will be set to the default colour.

  • By double-clicking on the Assume By Layer hyperlink. Items will automatically assume the colours of the layers they are inserted into, as set in the Layers Sub-Category the Drawing Configuration Category.

  • By manually entering the Colour Code field.

    Following selection, press OK. The selected colour code will then be displayed in the Symbol Colour field.

Flow Arrows Section

This section contains the following settings:

• If flow arrows are to be automatically placed at direction change mid points for subsequently drawn or updated pipes, make sure that the Insert Arrows at pipe segment mid point and Automatic Arrows checkboxes are checked.

• The Symbol Name field (below the Insert Arrows at pipe segment mid point checkbox) specifies which flow arrow symbol is used for flow arrows on change direction mid points of pipes. The symbol name is selected using the drop down list. It is recommended to use a flow arrow with the insertion point positioned at the center point of the symbol.

• If flow arrows are to be automatically placed at direction change end points for subsequently drawn or updated pipes, make sure that the Automatic Arrows checkbox is checked.

• The Symbol Name field (below the Automatic Arrows checkbox) specifies which flow arrow symbol is used for flow arrows on change-direction end points of pipes. The symbol name is selected using the drop down list.

Dual Flow Arrows Section

This section contains the following settings:

• The Offset Distance field is used to set the distance between the symbols used to indicate dual flow on pipes.

• The Symbol Name field specifies which flow arrow symbol is used for arrows indication dual flow. The symbol name is selected using the drop down list.

Values to Remember from Last Pipe Edit Section

The section contains the following checkboxes - Size, Fluid/Service, Number, Area, Specification, Insulation (Table), Insulation (Index), Insulation (Condition), Paint Code, Tracing (Number), Tracing (Size), Tracing (Type), and Project Field 1 to Project Field 20.

A project can be configured so that a value entered in a field in a Properties dialog is "remembered" by the same field when that Properties dialog is accessed again when labelling another, previously unlabelled, item of that type.

If, for example, the functionality is switched on for the pipe Number field, and a pipe is labelled with a value of "001". The next time a pipe is labelled for the first time, when the Properties dialog for this item is opened, the Number field will automatically be completed with the value "001". This can be replaced by another value if required. This new value will then be the "remembered" value for the pipe Number field.

This functionality is switched on and off for individual Properties dialog fields by checking and unchecking the checkboxes in this section.

Label Validation Across P&IDs Section

The project may be set to check that all pipe labels in all P&IDs in a project are unique.

• Select Prevent if users are to be prevented from entering project duplicate pipe labels. If this is attempted, an error message is displayed and the duplicate label may not be placed on the P&ID.

• Select Warn if users are to be warned if they enter project duplicate pipe labels. The entry of duplicate labels is permitted in this case, but an error message will be displayed on the P&ID, and will accompany the pipe label data when exported.

• If no uniqueness validation of pipe labels across P&IDs is required, select Ignore.

Duplicate pipe labels are not regarded as duplicates if the pipes in question are connected with cross-sheet connectors.

Size Consistency Section

If the synchronisation process is to check that nozzle and pipe sizes match and to report any mismatches as errors, check the Enforce Nozzle and Pipe Size Match checkbox.

If this checkbox is checked, any such mismatches must be corrected before the nozzles and pipes in question can be successfully synchronised.

Populate Specification in Database Section

If specification values are not going to be entered into the P&IDs, but populated in AVEVA P&ID Reports instead, check the Populate Spec in Database checkbox.

Inheritance Section

The values of pipe attributes may be inherited from the sheet attributes entered on the Advanced Drawing Properties sheet. The values entered for these sheet attributes may be values that are common to many items on the drawing, for example, the design area. The inheritance facility enables all items to inherit these common values. The attributes of items that do not share these common values may subsequently be edited manually using their properties sheets.

The Inheritance section is used to select which pipe attributes are to inherit values from which sheet attributes. As required, select for each pipe attribute the sheet attribute field from which values are to be inherited.

Sheet attribute field names are set up using the Drawing Information - Settings Sub-Category.

Cascade Settings Section

By default, when the properties of parent pipe label are edited, any changes to these properties may immediately be reflected in the labelling of the branches off that pipe.

If required, this cascading of changes may be disabled for selected properties. If this is required, check the Disabled Cascading in Branches checkbox.

To select the property fields to be excluded from cascading, select Browse adjacent to the Select Fields to Disable field. The Select Fields to Disable Cascading dialog box is then displayed:

Select the fields to be disabled from the list of values and then click OK. The Select Fields to Disable field will then list the numbers representing the selected fields.

Note: Fields specified for unique validation will still be cascaded regardless of these settings.

Legacy Settings Section

Check the Use Legacy Process Link checkbox if the pre-AVEVA P&ID 7.2 SP3 type of process links are to be used (PLK item type). These are known as "Legacy" or instrument process links.

If this checkbox is not checked (default setting), process links are drawn as pipes (for example, as branches between main pipes and offline items - PMA item type) in the process link pipe style.

Synchronize warning settings or unconnected items section

If, when a drawing is synchronized, a warning message is to be displayed on the drawing for "unconnected" items, for example, items for which owner details are not available, check the Display owner warning checkbox.

Select an alternative symbol to display at starting point of a new line section

If an alternative PSN or BSN type symbol is not required at the starting point of a new line, uncheck the Display Alternative Symbol checkbox. The example displays the starting point of a new line without an alternative PSN type symbol.

If an alternative PSN or BSN type symbol is to be used to display the starting point of a new line, check the Display Alternative Symbol checkbox.

Using the Display New Start Symbol(PSN) drop-down list, select the PSN type symbol to be displayed at the starting point of a new line. The starting point of a new line is displayed with a PSN type symbol, when drawn.

Note: Alternate symbol functionality can be used to graphically tag pipeline start and end points at tee or join intersections using the setting below combined with the user directive:
USER_ALTENATIVE_NODE_AT_TEE_INTERSECTION_ONLY=YES

Using the Display New Start Symbol(BSN) drop-down list, select the BSN type symbol to be displayed at the starting point of a new line at a tee or join intersection. The starting point of a new line intersection is displayed with a BSN type symbol, when drawn.

Select an alternative symbol to display at end point of a new line section

If an alternative PEN or BEN type symbol is not required at the end point of a new line, uncheck the Display Alternative Symbol checkbox. The example displays the end point of a new line without an alternative PEN type symbol.

If an alternative PEN or BEN type symbol is to be used to display the end point of a new line, check the Display Alternative Symbol checkbox.

Using the Display New End Symbol(PEN) drop-down list, select the PEN type symbol to be displayed at the end point of a new line. The end point of a new line is displayed with a PEN type symbol, when drawn.

Note: Alternate symbol functionality can be used to graphically tag pipeline start and end points at tee or join intersections using the setting below combined with the user directive:

USER_ALTENATIVE_NODE_AT_TEE_INTERSECTION_ONLY=YES

Using the Display New End Symbol(BEN) drop-down list, select the BEN type symbol to be displayed at the end point of a new line at a tee or join intersection. The end point of a new line intersection is displayed with a BEN type symbol, when drawn.

Highlight Changes Preview Section

By default, the Highlight Preview checkbox is checked, a highlight is used to preview the extent of changes to associated pipe component properties when a pipe property is modified using the Non-modal Properties dialog.

The following highlighting rules apply:

The Highlight Changes Preview Colour field defines the colour of the highlight preview.

The Browse button adjacent to the Highlight Changes Preview Colour field is used to select the highlight preview colour. On selection of the button, the colour selection dialog box is displayed:

The Colour Code can be selected using the following methods:

• Selection of one of the colours shown in the palette

• By double clicking the Assume Owner Colour hyperlink. the highlight preview will automatically assume the colour of the owning item, e.g., the colour of the owning pipe. When there is no owning item, the highlight preview will be set to the default colour.

• By double-clicking on the Assume By Layer hyperlink, the highlight preview will automatically assume the colour of the layer, as set in the Layers Sub-Category the Drawing Configuration Category.

• By manually entering the Colour Code field.

Following selection, press OK. The selected colour code will then be displayed in the Highlight Changes Preview Colour field.

Labels Sub-Category

The fields in this application pane are used to set up the pipe label configuration format.

The application pane is divided into the following sections.

Main Pipe Label Colour Section

The Main Pipe Label Colour field defines the colour of the pipe label that is selected in the pipe label set to represent the main values of the pipe.

The Browse button adjacent to the field is used to select the colour. On selection of the button, the colour selection dialog box is displayed:

The Colour Code can be selected using the following methods:

• Selection of one of the colours shown in the palette

• By double clicking the Assume Owner Colour hyperlink. Labels will automatically assume the colours labelled items. When there is no owning item, they will be set to the default colour.

• By double-clicking on the Assume By Layer hyperlink. Labels will automatically assume the colours of the layers they are inserted into, as set in the Layers Sub-Category the Drawing Configuration Category.

• By manually entering the Colour Code field.

Following selection, press OK. The selected colour code will then be displayed in the Main Pipe Label field.

Default Reporting Label Format Section

A pipe may be labelled with labels in various formats. One of these labels may be set as the default label, for example, the label that will be used to identify the pipe in the database. If required, such labels may be highlighted on drawings by having them displayed in a different colour.

If this is required, check the Default Reporting Label Format checkbox.

To select the colour, select Browse adjacent to the Default Reporting Label Colour field, and select the colour from the Colour dialog (see above). The number code of the selected colour is then displayed in the field.

Source and Destination Formats Section

A different display format from the normal display format may be used for pipe source and destination labels on a drawing, where the sources and/or destinations are different pipes. This section is used to switch on this facility and to define the required formats.

Check the Source Label Format and/or Destination Label Format checkboxes as required to switch on this facility for source/and or destination formats.

The buttons next to the Select Source Label Format and Select Destination Label Format fields are used to open the Tag Format Editor dialog in which the required format may defined. See the Display Label Format section.

Pipe Label Format Section

The Pipe Label Format fields are used to select the fields included in pipe labels, and the order in which they are displayed. Pipe labels may consist of up to 22 fields and must include Size, Number and Specification (unless the Populate Spec in Database checkbox is set) as a minimum.

The Browse button adjacent to the field is used to select the format. On selection of the button, the Pipe Label Format dialog box is displayed:

The Pipe Label Format can be selected by using the drop down lists. A field cannot be selected twice.

Note: A Project definable field can be selected without its unit, but not the other way round. When a project definable field for a field (for example, PROJ DEF 1 in Field 6), the list of values in the next field (e.g. Field 7) will include PROJ DEF 1 UNIT. The unit for a project definable field will only be available for selection for a field in these circumstances, for example, in the field after the project definable field itself.

Following selection, press OK. The selected Pipe Label Format will then be shown in the Pipe Label Format field as a set of values separated by commas, e.g. 1,3,5,6,10. The numbers represent label fields are follows:

1. Size

2. Fluid/Service

3. Number

4. Area

5. Specification

6. Insulation (Table)

7. Insulation (Index)

8. Insulation (Condition)

9. Paint Code

10. Tracing (No of Tracers)

11. Tracing (Size)

12. Tracing (Type)

13. to 52. Project1 (Project definable fields and units) to Project20 (Project definable fields and units)

Display Label Format Section

This section contains the following settings:

• The Display Label Format fields are used to select the types of data displayed in pipe labels, and the order in which they are displayed. Fields may appear in a different order from those of the "actual" pipe label, and fields that are in the "actual" pipe label may be left out, though additional fields may not be included.

  At least one display label format must be set up.

  Multiple display label formats may set up, one of which will be set as the default. When labelling pipes, the label will default to this format, but another format may be selected if required.

  The Browse button adjacent to the field is used to select the format. On selection of the button, the Select a Tag Format dialog is displayed:

  

  The dialog lists the existing display formats.

  To set a format as the default, select if from the list and select Set as Default. The current default format is indicated by the word "True" in the IsDefault column.

  To edit a format, select it and then select Edit. The Tag Format Editor dialog is then displayed. Edit the format.

  To delete a format, select it and then select Delete.

  To create a new format, select New. The Tag Format Editor dialog is then displayed.

  

  The Tag Format field cannot be edited. It displays the current display label format configuration (for example, the selected fields and delimiters).

  

  Enter a description of the format in the Description field. If required, enter any additional information in the Remarks field.

  The format is selected by using the drop down lists below these fields. A field cannot be selected twice.

  

  Unlike the "actual" pipe label format, which uses the delimiter entered in the Delimiter field for every part of the label, the display format may have different delimiters displayed after each label component. Enter a delimiter for each label field used, or leave blank if no delimiter is required.

  When the new display label format has been set up, select Save. The new format is then added to the list in the Select a Tag Format dialog. If required, set it as the default display label format as described above.

  Press OK. The default display label format will then be shown in the Pipe Label Format field, e.g. 1,-,2,-,3,/,4,-,5,. Refer to the previous section (above) for the meanings of these numbers.

• The Delimiter field defines the delimiter separating the Pipe Label Format fields. The use of a '|' character is restricted as this is the delimiter used in the transfer files to AVEVA P&ID Reports.

  Delimeters consisting of multiple characters may be selected.

• The Unique Validation field is used to specify which combination of fields in pipe labels are to be checked for uniqueness.

  The Browse button adjacent to the field is used to select the values. On selection of the button, the Unique Validation dialog box is displayed:

  

  The Unique Validation fields can be selected by using the drop down lists. Following selection, press OK, and the selected Unique Validation values will be shown in the Unique Validation field. e.g. 2, 9, 11.

• The Typical Fields field is used to set which fields are to be available when labelling typical pipes.

  The Browse button adjacent to the field is used to select the values. On selection of the button, the Select Fields for Typical dialog box is displayed:

  

  The dialog is used in the same way as the Unique Validation dialog box (above).

• The Trim Label Prefix field is used to specify the text prefix to the trim identifier in a trim label. Whenever a trim label is created on a vessel, this word appears in front of the main label. If no prefix is required, change the setting to NONE.

• If display labels for pipes are to be validated against a regular expression, check the Apply Regular Expression for Label checkbox.

  Enter the regular expression in the Advanced Format Options dialog. This is opened from the button adjacent to the Regular Expression for Label checkbox.

  Select the Advanced tab and enter the expression in the Regular Expression field.

  

  For help on editing Regular Expressions, click on the help link displayed on this tab.

  To test how the validation will work in practice, make an entry in the Test Data field of the Test tab, and press Test. A message will be displayed indicating whether or not the test data would be a valid entry.

  

  Note: Changes to drawings resulting from changes to the Display Label Format settings are not automatically implemented when project drawings are loaded. The user must trigger these changes "manually" in each drawing after it has loaded. Refer to Update Pipe Tags.

Project Definable Fields Section

• The Field 1 Name to Field 20 Name fields in the Project Definable Fields section are used to specify the boilerplate text for the project definable fields, which appear on the pipe labelling Properties dialog. These fields are not validated within AVEVA P&ID.

• If required, from the adjacent drop-down lists, select lists of values that entries in these fields must be chosen from. If this is not required, select the <NONE> value from the list (this is the default entry). Lists of values are set up in the List of Values Configuration Category of the Administration program.

• If required, from the Unit of Measure drop-down lists, select units of measure lists of values for the project definable fields.

• If a unit of measure is selected, the adjacent Decimal Precision drop-down list is enabled. A decimal precision value can be selected from 0 to 16.

• The project can be set to automatically split pipes on either side of breaks, if selected pipe properties are different on either side of the breaks are different. The Condition Break checkboxes are used to specify which properties will result in a pipe being split. Check the checkboxes as required.

Split Format Section

It is possible to place some fields of a pipe label above the pipe and the remainder below the pipe. This is termed Split Pipe Labelling and is controlled by the three fields in the Split Format section.

The Split After Field field is used to indicate which field in the pipe format to split on. The number entered here determines how many fields to count from the left of the pipe label before the split occurs.

The Y Offset Above Line and Y Offset Below Line fields are used to specify the positions of the two parts of the label as follows:

• If a pipe label symbol is not placed with a split label, the Y offset above line value is not used. The first part of the label is placed at the position specified by the user.

• If a pipe label symbol is placed with a split label, the first part of the label is offset by the amount specified in the Y Offset Above Line field from the insertion point of the pipe label symbol, plus the offset specified in the Symbol X Offset and Symbol Y Offset fields in the Pipe Label Symbols section. It is recommended that 0 is entered in this field.

• Whether or not a pipe label symbol is placed, the second part of the label is then offset from the first part of the label by the amount specified in the Y Offset Below Line field.

  Note: The Y Offset Above Line setting will be overridden by the Offset Distance setting if the Fix pipe label position checkbox is checked.

Define Split labels and offset for symbol Section

If split label formatting (see above) is to be used and a pipe labels symbol (see above) is to be used, up to four label fields may be placed before the split in the selected label symbol. This section is used to select which fields will be placed in the symbol and their to define their positions in the symbol.

Select the required fields from the list of values in the Label Type field.

Select <NONE> from the list where no field is required. Select Full Label to use the default display label format.

Select the position of each field relative to the insertion point of the label symbol in the Offset X and Offset Y fields.

Display Object Labels at Pipe Source/Destination Section

This section contains the following settings:

• Check the Use In line Item checkbox if the inline items attached to the start/end nodes of pipes are to be reported as pipe source or destination items in AVEVA P&ID Reports.

• The Item Type or name field works in conjunction with Use In line Item checkbox. In this field, enter item types and/or item names that can be reported as pipe source or destination items in AVEVA P&ID Reports. Item types/names not entered in this field will not be reported as pipe source or destination items.

Pipe Label Symbols Section

This section contains the following settings:

• If the Pipe Label Symbol checkbox is checked, a symbol will be placed with pipe labels. For example, a box may be placed around the labels.

The Symbol Name field is used to select the name of the symbol that will be placed with the pipe labels. There two symbol types available for selection, BPI and LIG.

Note: If LIG is selected on the SymbolType column, the Symbol X Offset and Symbol Y Offset fields are disabled.

• The Symbol X Offset and Symbol Y Offset fields control the offset of the labels in relation to the point selected when placing pipe symbols.

  Note: For split labels, the label insertion point may be further adjusted by the entry in the Y Offset Above Line field (see above).

If a BPI symbol type is selected and added to the drawing using the Properties dialog, the symbol and pipe can be positioned adjacent to the pipe.

If a BPI or LIG symbol type is selected and added to the drawing using the Symbol Explorer, the symbol and pipe label can be positioned on the pipe.

If a split label has been defined, the pipe label is displayed on more than one line when inserted using the P&ID application. See Define Split labels and offset for symbol Section.

Fix Single Pipe Label from owner segment Section

If the Fix pipe label position checkbox is checked, pipe labels subsequently placed will automatically be placed a fixed distance from the pipe segments they are labelling. This does not change the positioning of labels placed before the checkbox was checked.

Enter the distance that labels are to be placed from pipe segments in the Offset Distance field.

Automatic Pipe Label Placement Setting Section

If pipe labels are to be automatically placed in the middle of pipe segments, and rotated parallel to them, check the Automatic Pipe Label Placement checkbox.

The Offset Distance field will then become enabled. If required, enter the distance that pipe labels will be offset from pipes in this field.

Note: If the automatic placement option is required, the Rotation setting on the Label Options dialog for XPI and XBI label types should be set to NO in the Label Types Configuration Category.

Validation Sub-Category

This section is used to specify the permitted format of entries into selected pipe label fields.

In the fields provided, enter the following characters as required:

For example, if AaN is entered for the Number field, when a user is completing this field in the Pipe labelling Properties dialog, the first character must be an uppercase letter, the second a lower case letter, and the third a number.

The Advanced Format Options dialog is available from the button adjacent to each field.

To test how the validation will work in practice, make an entry in the Test Data field of the Test tab, and press Test. A message will be displayed indicating whether or not the test data would be a valid entry.

To directly edit the regular expression that comprises the validation entry, select the Advanced tab. The expression is displayed in the Regular Expression field and may be amended as required. For help on editing Regular Expressions, click on the help link displayed on this tab.

Automatic Tag Format Sub-Category

If the number fields of pipes are to be completed automatically (refer to Automatic Tags), the format of this field is defined using this sub-category.

If automatic tagging is to be used for pipes, check the Enable AutoNaming checkbox.

By default, the automatically incremented numbers that are part of automatic pipe tag numbers will be from the range of numbers specified for the drawing and sheet in the Drawing - Drawing List Sub-Category.

If the automatically incremented numbers should instead be a simple count for the project overall, check the Apply Project based Auto Naming checkbox.

The format of automatic pipe tags is defined in the Tag Expression field. A preview of a tag using the current definition is displayed in the Sample Tag Value field.

14. In the Tag Expression field, enter any fixed values such as prefixes and delimiters.

15. If pipe tags are to include an automatically incrementing number, place the cursor in the expression where this number is to be located, and click Insert Counter.

    The counter is added to the expression like so: [Counter].

16. Select the length of the counter number from the list in the Format field. Enter the number that the counter is to be incremented by for each pipe in the Increment By field.

17. A separate count may be applied for each value of specified pipe properties. For example, a separate count for each pipe specification.

    If this is required, check the Based on Counter Field checkbox, and select the button next to the Counter Reset Field field. The Select Fields dialog is then displayed:

    

    To specify that a separate count is to be applied to a property, select it from the Available Tag Properties list and click Insert Property. The property is then added to the Counter Reset Fields list.

    Click Clear to remove all properties from the Counter Reset Fields list.

    Click OK when all required fields have been selected.

    The selected fields are displayed in the Counter Reset Field field.

18. To clear the Tag Expression field, click Clear.

If a counter is in use, it may be reset to 0 for the project by selecting Reset Counter.

Index Branches

Note: For an overview on the use of the branch indexing functionality in a project, refer to Use of the Branch Index Functionality.

Piping networks can contain a collection of branches, each branch in a piping network can be automatically numbered using a unique tag value.

A project definable field can be allocated to display the branch index in the Labels Sub-Category of the Pipes Category in the AVEVA P&ID Project Administration program.

For example, the PROJ DEF 4 field has been selected in the Pipe Label Format dialog which is automatically allocated a value of 16 in the Pipe Label Format field.

The Project4 field has been selected in the Tag Format Editor dialog which is automatically allocated a value of 16 in the Display Label Format Fields field.

The Proj Def Field4 has been modified to Branch Index.

To apply index branches, check the Index Branches checkbox.

The format of index branch tag is defined in the Tag Expression field. A preview of a tag using the current definition is displayed in the Sample Tag Value field.

19. In the Tag Expression field, enter any fixed values such as prefixes and delimiters.

20. If index branch tags are to include an automatically incrementing number, place the cursor in the expression where this number is to be located, and click Insert Counter.

    The counter is added to the expression like so: [Counter].

21. Select the length of the counter number from the list in the Format field. Enter the number that the counter is to be incremented by for each branch in the Increment By field.

22. The index branch must be allocated to the project definable field. For example, [Proj Def 4].

    Select the button next to the Target Branch attribute field. The Select Fields dialog is then displayed:

    

    To specify the count to be applied to a property, select it from the Available Tag Properties list and click Insert Property. The property is then added in the Counter Reset Fields list. Only one property can be displayed in the Counter Reset Fields list.

    Click Clear to remove all properties from the Counter Reset Fields list.

    Click OK when the required property has been selected.

    The selected field is displayed in the Target Branch attribute field.

23. To clear the Tag Expression field, click Clear.

The example displays a piping network with two automatically numbered branches.

Drain Pipe Sub Category

From the Continuation Symbol Name list, select the drain pipe continuation symbol to be used in the project. The list consists of symbols of the DPS symbol item type.

From the Annotation Symbol Name list, select the drain pipe annotation symbol to be used in the project. The list consists of symbols of the XPA symbol item type.
