Consistency Check

The Consistency Check command can be executed on a single shape, several shapes or on all shapes in the drawing. This function will perform two kinds of checks on the selected items. It will check the consistency between the drawing and the database as well as performing an engineering check.

In case any inconsistencies are found, these will be listed in the Consistency Check Result window. Inconsistencies are classified as Errors, Warnings and Informational messages as indicated by the status icon.

The columns are as follows:

1.

The icon indicates the severity of the problem (Error, Warning or Information).

2.

Name of the Visio shape that the problem is related to.

Connection number of the shape which the problem is related to. This is only shown in case the problem is related to a certain connection point on the shape.

Name of DB element that the shape is related to. This is only shown in case the problem is related to a shape that has a corresponding DB element.

Page number in the drawing on which the related shape exists. This is only shown in case the message is related to a shape.

Problem text. See below for the list of problems that can be detected by the Consistency Check function.

Corrective action

In case any corrective action has been taken, this will be indicated in this column.

By clicking on each line in the dialogue, the corresponding shape will be highlighted in the drawing. In case the shape is not visible in the current view, the system will pan and if necessary zoom out to make the entire shape visible.

The system will also attempt to bring back the drawing to a consistent state against the database in case any inconsistencies have been detected. This normally means that shapes will be disconnected or undefined in the drawing. No automatic updates will be done to the database.

Below is a table showing the different checks that are performed during the Consistency Check operation.

Corrective action

Not connected to the same point on element in DB

Disconnect in dwg

The connection number indicated by the shape connection point differs from the one get from arrive/leave attribute.

Not connected to the same element in DB

Disconnect in dwg

The element connected to the shape on the drawing is not the same as the element pointed by the database reference.

Connected pipeline X has different attribute FLUR

Pipeline connected to the shape on the drawing has different attribute FLUR than the pipeline that the shape belongs to.

Connected shape's element does not exist in DB

Disconnect in dwg

The shape is connected on the drawing to the element which does not have a database representation.

Element not connected in DB

Disconnect in dwg

Similar to the above, the shape is connected on the drawing, but not in the database.

Illegal connection between different line types

Disconnect in dwg

Occurs when connected inline components and tubes are placed below different line types (Pipelines and Instrumentation lines).

Nozzle not related with an equipment item

Undefine shapes

Nozzle is defined in the database under some equipment, but not connected to any defined item on the drawing.

Electrical connection not related with an equipment item

Electrical connection is defined in the database under some equipment, but not connected to any defined item on the drawing.

Shape is related to a different equipment item than in the database

The nozzle or electrical connection is defined in the database under some equipment, but on the drawing it is connected to another item.

The database element is missing

The shape is defined, but the related database element is missing.

The database element is connected at the connection point, but the shape is not

The element in the database is connected, but its representation on the drawing (shape) is not.

Shape has only to/from flows

The shape has only 'to' or 'from' connections.

Only X of Y cable members are released to 3D (performed for Multi-cables)

SPREF of component is not set (Nulref)

SPREF not of SPCOMPONENT type

SPREF of component is set to an element different than SPCOMPONENT (occurs when current settings do not allow out-of-spec components).

Boresizes does not match (between current and connected shape)

Widths does not match

Heights does not match

Shape do not match

Shapes (OVAL, CIRC, RECT) of connected shapes are different (for HVAC).

Ductsizes/shapes do not match

Widths, heights or shapes (OVAL, CIRC, RECT) of connected shapes are different (for connection between HVAC elements and e.g. nozzles.

Boresize not set

Bore size is unset (for piping and instrumentation).

Ductsize not set

Duct size (height or width) is not set (for HVAC).

Shape (OVAL, CIRC, RECT) is not set (for HVAC).

Shape not connected at connection point

One of connection points is not connected to any item.

Shape is not defined in the DB

Shape is not defined.

Shape not connected to other OPC

Occurs for OPC's when their OPCREF is not set (is not pointing to other OCP).

Attribute X has bad reference(s) to Y. Referenced item(s) missing in the MDB.

Reference in attribute X is pointing to an element Y which is not valid in the MDB. One attribute can have many references, in which case only bad references will be reported.

Note:

This will not report unset references, only references set to invalid objects are listed.

Instrument relationship shape is not defined on drawing but it connects items that are connected in DB.

‘The shape has been defined’ message appear and relationship line will be defined.

Relationship shape supposed to be defined because it connects valid items and items are connected in DB but for some reason it was not defined.

Can not connect Instrument relationship line shape to this connection point

Disconnect in dwg.

User is trying connect relationship shape to some component connection point that was designed for process line.

Instrument relationship line shape should be connected to offline instrument or actuator from at least one end.

Disconnect in dwg

Situation where the system detects that relationship shape is connected with both ends but none of the connected items are actuators nor offline instruments.

Twin connection.

Disconnect in dwg

Message when the system detects that Offline instrument or Actuator has more than one connection to the same item.

One end of Instrument relationship line is not connected.

Situation where relationship shape line has one end disconnected.

Instrument relationship line is not connected.

Situation where relationship line has both ends disconnected.

There is also a functionality which allows exporting the Message Log and Consistency Check results to a txt or xls file. This is available in the right click context menu of the Message Log and Consistency Check window.

The Consistency Check command can be issued through the following UI commands:

•

Object pull-down menu

•

Shape right-click menu (also works on a selection of shapes)

•

Drawing background right-click menu

A summary of the consistency check result can also be seen in the Message Log. In case no inconsistencies are detected, the Consistency Check Result pane will not appear.
