CHAPTER 1

1 Introduction

Pipe routing is probably the activity that consumes most time on any large project and it is also one, which causes the most problems. Pipe routing in PDMS has always been one of the major strengths of the system, as you will discover in this module.

1.1 Aim

The aim of the course is to provide the skills required to use the PDMS Piping Design application in the most productive way, to introduce some of the techniques that are used in the other Design applications and have an understanding of Piping components, routing, checking isometrics and simple Clash detection.

1.2 Objectives

At the end of this Piping Design training course, the participants will able to:

ƒ Understand the basic concepts of Pipes and Branches.

ƒ Understand the use of piping specifications in AVEVA Plant.

ƒ Understand the concept of branch heads and tails and the importance of component list order and flow direction within a branch.

ƒ Create position and orientate piping components.

ƒ Orient and position components in falling pipelines.

ƒ Apply Insulation and Tracing to the pipelines

ƒ Use more complex positioning with relation to other design items.

ƒ Run Data Consistency Checks to screen or file including Parameters and Tolerances and to understand most of the diagnostic messages.

ƒ Perform simple Clash Checks

ƒ Perform Check Isometrics.

ƒ Create and use Piping Design Assemblies.

ƒ Understand pipe splitting on components or by using Assemblies. 1.3 Prerequisites

The participants must have completed the PDMS Introduction and Basics course.

1.4 Course Structure

Training will consist of oral and visual presentations, demonstrations and set exercises. Each workstation will have a training project, populated with model objects. This will be used by the trainees to practice their methods, and complete the set exercises.

CHAPTER 2

2 Pipework Modelling

The following Chapter describes how PDMS is used for modelling pipework. There is a separate design hierarchy for pipe routing, as shown below. In principle, each pipe element may own a number of branches. In turn, branches may own a number of piping components like valves and reducers.

The difference between pipes and branches is that a branch is only considered to have two ends, while a pipe may have any number of ends, depending on the number of branches it owns.

Below shows a pipe with three ends and two branches. The second branch is connected to the first at the tee.

This brings in another rule that says that although a branch only has two ends, it may own components (in this case a tee), which connects to other branches. These simple concepts enable any number of piping configurations to be developed, and form the basis of all the PDMS Pipework you will encounter.

Alternatively the branch could leave the tee through the offline leg as shown.

2.1 Entering a Design Session

To start the PDMS application, Select All Programs > AVEVA > PDMS 12.0 > Run PDMS

Your Trainer will provide a shortcut User Name and Password to PDMS but typically it will be as follows:

On the AVEVA PDMS Login box, enter

Project SAM

Username USERA

Password A

MDB TRAINA

Module Design

and then click OK

A default screen layout will be displayed comprising the general menu bar for the application and a Design Explorer window showing all the objects from the current project database. You can reposition and, in some cases, resize Designs windows. If you select a named file from the load form selector then the screen will be returned to the layout at the time of saving.

Once the Design application has been started, check that you are running in the Pipework application, this can be seen on the top of the design framework, if it does not say Pipework Application, then select Design > Pipework, this will then change to the correct application.

2.2 Piping Specifications

In the same way that design offices have standard piping specifications, PDMS has a set of specifications from which you can choose. In fact all the components you will use in PDMS must be defined in the Catalogue and be placed in a Specification before you can use them. In the Training Project there are three such specifications:

A1A = ANSI CLASS 150 CARBON STEEL

A3B = ANSI CLASS 300 CARBON STEEL

F1C = ANSI CLASS 150 STAINLESS STEEL

(13)

www.aveva.com

2.3 Setting the Appropriate Specification

The first task when building a pipe is to decide which specification you are going to use. For the Training Project, the first letter in the pipe name represents the specification to be used. For example, the pipe /150-B-5 has the letter ‘B’ to represent the specification.

The specification letters are as follows: - A = /A1A

B = /A3B C = /F1C

Having decided on the appropriate specification, this is then set as an attribute of the pipe. Any subsequent branches will automatically be assigned with the same specification (although this can be re-specified if required).

When you enter the Piping Application the Default Specification Form is displayed.

The default Insulation and Tracing Specifications can also be set using this form but are only active when ticked.

2.4 Pipework Toolbar

The Pipework Toolbar is used to Manipulate Pipes, Branches and Branch Components.

The default Piping Specification can be reset using this Icon.

2.5 Pipe Creation Form

To Display the Pipe Creation form, select the Show pipe creation form icon from the Pipework Toolbar

The Create Pipe form is now displayed

Pipes hold reference data i.e. Insulation and Tracing Specs, and also the Temperature and Pressure of the pipe.

Before creating the pipe we must first navigate to the correct zone using the Design Explorer,

The Bore field indicated on the form is the nominal bore for this pipe and does not affect the pipe route.

2.6 Pipe Branches

Branches serve two purposes:

• They define the start and finish points of a pipe route (known as the Head and Tail in PDMS). • They own the piping components, which define the route.

The position and order of the piping components below branch level determine the physical route. In PDMS you only ever need to consider the fittings, because the pipe that appears between fittings is automatically set (or implied) by PDMS according to the specifications of the fittings.

(15)

www.aveva.com

2.7 Pipe Branch Heads and Tails

All branches need to have a start and end point. These can be a position in space (3D co-ordinates), the flange face of a nozzle, a tee or various other points in your design. Heads and tails are set up via a series of attributes that belong to the branch element.

L

Note the Branch head is at the face of Nozzle 1 and the Branch Tail is at the face of Nozzle 2.

2.7.1 Attributes for heads of branches

HPOS The position in the zone where the branch starts.

HCON The connection type of the branch end (Up to a 4 character code for flanged, butt weld, screwed, etc.).

HDIR The direction in which the start of the branch is pointing (as if you were looking down the bore). HBOR The bore of the pipe (this can be metric or imperial).

HREF The name of the item to which the branch head is connected (e.g. /C1101-N1). If this is not set, then the branch is open to the atmosphere for a vent or drain.

HSTU This is a reference to the catalogue, which determines the material of the first piece of pipe, between the start of the branch and the first fitting (this still needs to be set, even if there is a fitting connected directly to the head).

2.7.2 Attributes for tails of branches

TPOS The position in the zone where the branch ends.

TCON The connection type of the branch end (Up to a 4 character code for flanged, butt weld, screwed, etc.).

TDIR The direction in which the end of the branch is pointing (as if you were looking back down the bore). TBOR The bore of the pipe (this can be metric or imperial).

TREF The name of the item to which the branch tail is connected (e.g. /150-A-3). If this is not set, then the branch is open to the atmosphere for a vent or drain.

L

You do not need to specify each of these attributes every time you create a branch. On most occasions

when you set a head or tail, you will be connecting to another pipe or to a nozzle. The act of connecting to another item sets all the attributes at once.

A Pipe is just an administration element it is the pipe Branch that holds the geometry. When you select

Apply on the Pipe Form the Modify Pipe form is automatically displayed so that the branch head and tails can be specified.

(16)

www.aveva.com

2.8 Pipe Branch Head / Tail Positioned Explicitly

After clicking the Change button on the Head Detail pane above, the following form appears:

When setting the Branch Head or Tail explicitly you need to specify each of the previously described Branch attributes.

Bore: Nominal Bore size of the pipe. The pull-down list contains all sizes available in the specification. Connection: Short code eg: FBB,FBD defining the Head connection type

Position: Position in world co-ordinates

The Head Direction is the direction of the flow and the Tail Direction is opposite to the flow.

Refer to the AVEVA coding standards for a full

definition of connection types.

(17)

www.aveva.com

2.9 Pipe Branch Head / Tail Connected

Use the Change button on the Head Connection pane to connect the head to another database item, e.g.: Nozzle, Branch Head/Tail, etc

Using the graphical Pick Button, select an item to connect the pipe head to.

A list of available connections form is displayed, Select the appropriate connection and then press Connect.

This sets the pipe head attributes HPOS and HDIR

2.10 Pipe Branch Components (Pipe Fittings)

When you first define a head and tail for a branch, your branch will consist of one piece of pipe running in a straight line between the head and tail positions. This will appear as a dotted line between the two points unless the head and tail are aligned along a common axis and have the same bore. (The dotted line indicates that the branch route is geometrically incorrect.)

The next step in designing a pipe is to create and position a series of fittings, which define the pipe route you require. Just as on a drawing board, you need to decide which piping components are needed in order to satisfy the requirements of the process. The components must be arranged so that the pipe meets its design needs. However, unlike on the drawing board, you do not need to know any fitting dimensions; PDMS derives these automatically from the catalogue.

To create components, you need to select an item from the list of fittings available to you from the associated piping specification. Typical fitting types are Elbows, Tees, Reducers, Flanges, Gaskets and Valves etc. There is some intelligence build into the PDMS forms so that by placing for example a valve the associated Gaskets and Flanges will also be created.

For all piping components, you will need to carry out the following steps: -

(18)

www.aveva.com

The tube is not created explicitly; it is created automatically and implied between adjacent fittings.

2.11 Creating Branch Components (Pipe Fittings)

The “Component Types” list shows the piping components that are available in the current piping specification, set at the Pipe and Branch level.

Using the Select button, you could select components from an alternative specification if required.

Components are created by selecting the required fitting from the list

2.12 Component Creation Form

The Component Creation form shows details of all the Sub-Types available in the piping specification. .

For example a Flange may be Slip-on, Weld Neck, Screwed or Blind.

You will be required to select the Sub-Type you require.

Items are created in order with or against the flow of the pipe.

A tick box is available to automatically create adjacent components. This is very useful for creating the flanges of in-line flanged components. For example, if a Valve is added the gaskets and flanges will also be added.

(19)

www.aveva.com

2.13 Component Selection Form

From the Pipework Toolbar, select the Show pipe component selection form icon, the component Selection form is now displayed.

2.13.1 The components Tab

The Component Selection form can be used to change an existing component Sub Type or Spec. after it has been added, preserving its connections to adjoining components wherever possible. The selected component type will be displayed in the Type window, i.e. Flange etc.

From the available Sub-Types list select the SLIP ON FLANGE. The Component is changed and this can be seen in the graphical view

If the component has a different fitting-to-fitting length this can be reconnected using the Reconnection Button.

2.13.3 The Errors Tab

The Errors tab displays any errors which may result if an unsuccessful Reconnection operation is attempted.

2.13.4 The Options tab

The Descriptions of the component can be shown in Full, R Text, S Text, T Text or just as a Cat-Ref.

Tag component can be used to turn the Component marker on and off (on by default).

Tag constraints can be used to turn on and off the highlighting of Components which could give bad connectivity if an adjacent Component is changed.

Auto reconnect if selected, automates the function of the Reconnection button on the

Components tab. Errors which may result if an unsuccessful Reconnection operation is attempted will automatically appear on the Errors panel

Reconn. free ends if selected, re-establishes connectivity if the Pipe Head (or Tail) becomes disconnected as a result of Component reselection

Ignore positioned if selected, ignores elements which have their RLOCK attribute set to 0. (RLOCK is the attribute for the branch members creation status code used by Router.) Selecting this option does not stop the model editor moving the Component, but by default the Component with RLOCK= 0 will not be moved when it is reconnected to the Component being changed

(21)

www.aveva.com

2.14 Branch Components List Order

With equipment and structures, the order in which you create items is of no importance to the final outcome. With piping components, the order in which they are laid out, as well as their individual positions and orientations, determines the final pipe route.

To help with this a Component Position Pointer is displayed.

Below is an example Design Explorer list showing the components of a branch /100-B-1/B1

As you can see by default there is no TUBE shown in the explorer window,

2.15 Typical Design Explorer showing Tube

Tube is shown by changing the Explorer setting

Settings > Explorer

SelectShow TUBI/ROD

(22)

www.aveva.com

When using PDMS the list order will become second nature to you after you have created a number of branches, but for the time being you should be aware of it and should consider carefully where your next item is going to be inserted by watching the Component pointer and Design Explorer.

L

When you are creating a component at the pipe branch head or pipe branch tail you must ensure that

(23)

2.16 Arrive and Leave Points

Piping components have P–points (similar to those for equipment primitives).

The significance of P–points is two–fold. First, they define the connection points, and second, they determine the branch flow through the component by means of Arrive and Leave attributes.

For the reducer shown below, you will see that the large end is at P1 and the small end is at P2. If you use this component to increase the bore of the branch, the flow in the direction of the branch will be from P2 to P1. In order to tell PDMS the flow direction you want, you set two numeric attributes, Arrive and Leave, to the p–point numbers you want. In this case, Arrive would be set to 2 and Leave would be set to 1. (The default is Arrive 1 Leave 2). This is included for information, as the forms and menus will handle all connections.

2.17 Quick Pipe Routing

The Quick Pipe Routing Handle has three parts,

Extend Route Handle – This is used to extend the route in the direction indicated by

the handle.

Cardinal Direction Handles - These are used to change the direction of the routing to one of the cardinal directions from the current frame of reference.

Rotational Handles These allow the extended route handle to be interactively

directed by the user.

The quick pipe routing handle is used to define a routing vector within the constraints of the currently selected badly defined route. A badly defined route is defined in general terms as where either, there is a bad alignment between two components, the head or tail of a branch is incomplete, i.e. where the head/tail attributes are left in their default state, the head/tail is positioned but not connected and the head/tail connection type is unset.

This usually equates to the dotted line representation of implied tube, where implied tube cannot be drawn. An exception to the above could be where a Pipe Branch does not have specification reference set.

The handle can be dragged by using either primary or secondary mouse buttons. By default the handle will move in multiples of the currently defined linear increments.

If the secondary mouse button is clicked as the cursor is over the pipe routing handle, the user will be presented with a context sensitive menu. The menu will display the available options which relate to the drag.

2.18 Extended Handle Pop-ups

The following options are available on the Extend Handle before a drag.

Enter Offset This gives the Constrained Move form which allows you to enter an offset from the current handle’s position in the current routing direction.

Cardinal Direction Handles Extend Route Handle Rotational Handles

(25)

www.aveva.com

Enter Leg Length This gives the Leg Length form which lets you enter an absolute distance of the handle from the last previous change in the direction’s position.

Distance From Origin This displays the Explicit Distance form which allows you to enter an absolute distance of the handle from the previous component’s origin position.

Extend Through Feature This allows you to identify features with which to align, along the current

route direction.

Orient to Point This directs the handle either directly to a point feature or rotates about the vertical axis, maintaining horizontal offset, when a linear feature is

identified.

Align with Direction This allows you to identify features with which the handle is to be aligned.

Explicit Direction This gives the Enter Direction for <direction> Axis form which lets you enter

an explicit direction for the handle.

Component Choice This allows you to select the type of Component that is created by the Routing Handle when a change in direction occurs. The Component can be set to either Elbows or Bends.

Distance Feedback This allows you to select how the Routing Handle displays distance

feedback. This can be set to either Offset (offset from the previous handle’s position), Leg Length (distance of the handle from the last previous change in direction’s position), or FromOrigin (distance of the handle from the previous Component’s origin position). Use the D 'hotkey' to cycle through

the options.

Show Rotation Handles This toggles the display of the Rotation Handles (selected by default).

Cancel This returns the handle and selection to its original state before the drag The following option is only available when the end being routed to is ill-defined, i.e. there is no End Route Handle displayed:

Connect To This enables you to select an element which the route end can be connected to, eg unconnected Nozzles, Tees etc.

The following options are available on the Extend Handle on completion of a drag, i.e. when the secondary mouse button has been used to drag the handle and no special actions are active:

Extend This leaves the handle at the shown position.

Cancel This returns the handle and selection to its original state before the drag. The following options are available when in “snap to feature mode” and the end being routed to is ill-defined or unconnected and the identified feature is a connectable p-point of an item to which an end can be connected, e.g. a Nozzle with no connection reference set:

Extend This leaves the handle at the shown position

Connect This leaves the handle at the shown position and connects the ill-defined

end to the identified target.

Connect and Complete This establishes a connection to the identified item and completes the route and exits the route mode when applicable.

Cancel This returns the handle back to its original state before the drag.

The following options are available when in “snap to feature mode” and the end being routed to is well defined and the identified feature is the End Route Handle.

Extend leaves the handle at the shown position

Complete completes the route and exits the route mode when applicable.

2.19 Rotational Handle Pop-ups

The following options are available on the Rotation Handle before a drag

Enter Value This gives the Rotate Selection About form, enabling you to enter a value to rotate the graphical selection about the selected rotational axis

Orient to Point This allows you to pick a p-line through a point with which to orient the Rotation Handle.

Align with Direction This allows you to identify features with which the handle is to be aligned. Planes will be displayed to indicate a p-point direction (pointer symbol) or a p-line direction (symbol). Clicking and releasing the SHIFT key will reverse the direction of the handle.

Align With Thisdisplays the Enter Direction For <direction> Axis form which allows you to align the handle with a specified direction, or as close as possible to the given direction, about the axis of the Branch.

Rotate Handle Allows you to rotate the Locator Handle, using the same movement options as the main Rotation Handle menu. These options move the Locator Handle only, they do not move the Graphical Selection. Alternatively a 'freehand' movement of the Rotate Handle can be accomplished by clicking the H key with the handle selected and the left mouse button held down.

The Locator Handle may be rotated independently of the Graphical Selection in order to change the frame of reference for the next operation on the Graphical Selection.

Rotate Handle>To World This option aligns the Locator Handle with the World co-ordinate system, without rotating the Graphical Selection.

The Locator Handle Y axis points North, and the Z axis points Up.

2.20 Quick Pipe Routing (Example)

The tasks of setting up pipes, branches and components are simplified by the use of forms and menus. The main thing to remember when using the application is which specification you are currently using as a default.

The course exercises and examples will illustrate different means of pipe routing by giving examples of many of the situations you will encounter.

The quick pipe routing functionality will allow the user to correct the path of a pipe wherever there is an ill defined route within a branch, i.e. where the dotted line is displayed instead of implied tube.

Highlight the dotted line, and select the Model Editor icon from the Model Editor Toolbar. The Pipe Component Modification handle will now appear at the component leave end.

Enter the feature highlighting mode by clicking the F key on the keyboard or by selecting Selection > Feature Highlighting from the pull down menu

Select the pipe component modification handle and press the right mouse button. From the pop-up select

Component Choice > Use Bends. Holding down the left mouse button, drag the pipe modification handle across to theother end and still holding down the left mouse button, click the right mouse button. A second pop-up appears, select complete

The bend and the implied tube are added to complete the route

L

The bend that has been added by the system can later be

changed to a smaller radius bend or an elbow.

L

If the component choice had been Use Elbows, then this

would not have completed the route due the default elbow component is the first elbow component in the specification i.e. a 45 degree elbow

L

Selecting the Pipe component modification handle with the

right hand mouse button will result in the implied tube been shown translucently

Make sure when creating your components you have set the Create Components Form to the correct

Branch using the <Set Branch> button.

Exercise 3 - Building the Pipework

Start to build up the Pipework on the plant. Refer to the drawings for positions and components required along each pipe. Remember to select the correct specification for each pipe. In general, the naming convention of the pipes is built up from pipe size, the third character of the specification (A3B) and a line number.

Initially, create the following pipes: Pipe 80-B-7

When you create this pipe if the Nozzles are correct, i.e. both the same size and inline the tube will be implied and displayed. You should only need to create the flange connections, remember this is done by being positioned at the branch level in the Design Explorer.

(44)

www.aveva.com

Pipe 150-B-6

The Flanges and elbows at both the Head and Tail of this pipe should be created fitting to fitting. The elbows are rotated as required using Model Editor. This is quite a simple pipe so it could easily be routed using quick route mode.

The First elbow is rotated using Model Editor to face East.

(45)

www.aveva.com

Pipe 250-B-5

The Elbow can be lifted in-line with the next item in the branch using The Align selection / component Icon

Create and position a Tee as described earlier. Reducers are created in a similar way to Tees; make sure you select the correct Icon when selecting the bore.

(46)

www.aveva.com

Pipe 200-B-4

The bottom section of this pipe has a small offset of about 15 Deg. The two bottom elbows should be lined using Align selection / component as described earlier.

The Elbow can be directed to face towards the next elbow using the

Direct selection / component Icon.

Navigate to the next Elbow and direct it in a similar way using the Direct selection / component Icon. 100-C-13

This pipe must be routed to piping spec F1C as it is stainless steel, the pipe head can be connected as we have done before. The pipe tail however must be created explicitly.

CHAPTER 5

5 Data Consistency Checker

This Chapter shows you how to check the logical consistency of your design data, enabling you to find and correct the most common types of design error.

You will normally carry out data consistency checks before you run the clash detection facilities. It is more convenient to do a data check on individual pipes than to do the whole Plant in one go. There may be too many errors to sort out at once.

5.1 Possible Types of Data Error

The data consistency checking utility, available within Design’s Piping and Structural applications, checks the following aspects of your design (piping examples shown):

5.1.1 Angular Alignment

Checks that components which are to be connected together are aligned in the same direction:

PL is E

PA is W30N

N

5.1.2 Axial Alignment

Checks that components which are to be connected together are aligned on a common axis:

offset axes N

5.1.3 Consistent Bores

Checks that components which are to be connected together have consistent bores: Leave Bore

50

Arrive Bore 100

5.1.4 Connection Types

Checks that components which are to be connected together have compatible connection types: Flange

connection

Screwed connection 5.1.5 Minimum Tube Length

Checks that no length of tube is less than a prescribed minimum (which may depend on its bore).

Component A Component B

Tube too short to allow

(66)

www.aveva.com

5.2 Starting the Data Consistency Checks

To carry out data consistency checking from within the Piping application, select Utilities>Data Consistency. You will see the following form:

By using this form, you can generate a diagnostic report on the data consistency of any part of your design. You may list the report on your screen (in the area in the lower half of the form), or you may send it to a file from which you can print a hard copy version. Select Screen or File and, in the latter case, specify the directory and filename. Choose the hierarchic level at which you want to check the design using the Check list near top left of the form. The default is the current element.

Navigate to Pipe 100-B-8

Select Check Pipe and Apply

5.2.1 Specifying Parameters and Tolerances

The data checking utility allows a margin of acceptable error before it diagnoses that you may have a problem. These built–in tolerances have default values, but you may set your own values if you prefer. Select the Piping Button

(67)

www.aveva.com

5.2.2 Minimum Tube length

As an example, by default your report will warn you of all lengths of tube in your design which are shorter than 100mm. This allows you to decide whether each such length is adequate for welding procedures, bolt withdrawal, access, and so on. You can change the acceptable minimum length from 100mm, and may set different minima for up to ten different pipe bore ranges if you wish.

For example:

A minimum length of 150mm for bores between 25 and 50. A minimum length of 300mm for bores between 50 and 100.

To change any of the consistency check tolerances, use the appropriate Parameters button on the form (Piping for our current examples). And then select Tube Range.

You will see a subsidiary form on which you can change any of the current tolerances before carrying out the data checks.

5.3 Data Consistency Check Report Format

The report comprises a header, giving the date and time, followed by an itemised list of the elements being checked, together with numbered diagnostic messages describing any potential problems.

For example:

DATE 11 FEBRUARY 99 TIME 14.12 PIPE /PIPE2

BRAN /PIPE2/B1

B 10 TAIL REFERENCE NOT SET END

If no problems are found, you will see the message: *** NO DATA INCONSISTENCIES ***

5.3.1 Data Consistency Diagnostic Messages

You will find a full list of the data consistency diagnostic messages, each identified by a reference number, in the DESIGN Reference Manual. With experience, you will be able to identify which messages indicate errors which must be corrected, and which are merely warnings of potential problems.

As an example, we will consider the design feature shown below, namely a Pipe to Pipe connection, and will look at some of the messages which might result.

(68)

www.aveva.com

HEAD TAIL PIPE A PIPE B GASK FLAN FLOW GBD HCONN FBD TCONN GBD FBD D430

(On GASK) B230 (On FLAN)E730

A230

PArrive PLeave

The connection as shown is a valid one. If any of the connection types were changed, you might see the following messages:

A230 CONNECTION TYPE HCONN NOT SAME AS TERMINAL CONNECTION TYPE The connection types FBD-FBD in this example must be the same.

B230 CONNECTION TYPE TCONN NOT SAME AS TERMINAL CONNECTION TYPE The connection types GBD-GBD in this example must be the same.

D430 BAD ARRIVE CONNECTION TYPE

The connection types GBD-FBD in this example must be listed as compatible in the COCO tables. E730 LEAVE CONNECTION TYPE (of the Flange) NOT COMPATIBLE WITH TCONN

The connection types FBD-GBD in this example must be listed as compatible in the COCO tables.

5.4 Some Examples of Data Consistency Diagnostic Messages

The following examples explain the significance of some of the messages you might see during this training course:

5.4.1 Branch Head Errors

The following diagnostics apply only to the Head of a Branch: A 10 HEAD REFERENCE NOT SET

The Head reference should only be unset (i.e. zero) if the Head Connection Type HCONN is set to OPEN, VENT, CLOS or DRAN.

A 20 HEAD REFERENCE POINTS TO NONEXISTENT ELEMENT

This error would result from the deletion of a component, such as a Nozzle, to which the Head of the Branch was originally connected.

A 30 BAD HEAD RETURN REFERENCE

The Head is connected to an element that does not refer back to the Branch. This can occur when the Head of a Branch is connected to another Branch, implying that a Tee should be placed somewhere along the second Branch. The error can also occur when two or more branches are inadvertently connected to the same terminal.

A200 DIRECTION HDIR NOT SAME AS TERMINAL DIRECTION

If the Head is connected to a terminal, such as a Nozzle or Tee, then the direction HDIR should always be identical to that of the appropriate p–point of the terminal.

A210 POSITION HPOS NOT SAME AS TERMINAL POSITION

If the Head is connected to a terminal, such as a Nozzle or Tee, then the position HPOS should always be identical to that of the appropriate p–point of the terminal.

(69)

www.aveva.com

A230 CONNECTION TYPE HCONN NOT SAME AS TERMINAL CONNECTION TYPE

If the Head is connected to a terminal, such as a Nozzle or Tee, then the connection type HCONN should always be identical to that of the appropriate p–point of the terminal.

A300 REFERENCE HSTUBE UNSET

There is more than 1mm of tube between the Head and the p–arrive of the first Component (or the Tail), but HSTUBE is unset.

A310 REFERENCE HSTUBE REFERS TO A NONEXISTENT SPCOM This may occur if part of the Specification has been deleted. A320 HSTUBE PROBLEM, CATREF IN SPCOM IS UNSET

This indicates an error in the Specification.

A330 HSTUBE PROBLEM, CATREF IN THE SPCOM REFERS TO NONEXISTENT Catalogue COMPONENT

This may occur if part of the Catalogue has been deleted or if the CATREF is unset. A400 HBORE NOT SAME AS BORE OF HSTUBE

The bore of any tube leading from the Head, determined from the Catalogue, should always be identical to HBORE.

A410 HCON NOT COMPATIBLE WITH CONNECTION TYPE OF HSTUBE

The connection type of any tube leading from the Head, determined from the Catalogue, should be compatible with HCONN.

A420 ISPEC REFERENCE POINTS TO NONEXISTENT ELEMENT

This error would occur if, for example, the Insulation Specification pointed to by ISPEC had been deleted.

5.4.2 Branch Tail Errors

The same type of errors may occur to the Tail of a Branch. The message numbers are the same as for the Head errors but are preceded by a B.

B 10 TAIL REFERENCE NOT SET

The Tail reference should only be unset (i.e. zero) if the Tail connection type TCONN is set to OPEN, VENT, CLOS or DRAN.

5.4.3 Plain Branch Errors

The following diagnostics can occur only for Branches with no piping components: C500 TUBE TOO SHORT BETWEEN HEAD AND TAIL

The distance between the Head position, HPOS, and the Tail position, TPOS, is greater than zero and less than the specified minimum tube length (default: 100mm).

C510 BAD HEAD TO TAIL GEOMETRY

Either the Head position, HPOS, does not lie at a positive distance along the line through TPOS in the direction TDIR or the Tail position, TPOS, does not lie at a positive distance along the line through HPOS in the direction HDIR.
