PipingNetworkSegment¶
Overview¶
Class
The piping limited by a Node and a Break, Node and Connector, two Nodes, two Breaks, two Connectors or a Break and a Connector. The last five providing there are no Breaks or Connectors in between. In the last three cases the Segment will coincide with a Piping Branch (from http://data.posccaesar.org/rdl/RDS267704).

Implementation in Proteus Schema
The class is implemented as a Proteus XML element with RDL reference.
Tag: <PipingNetworkSegment>
RDL reference: PIPING NETWORK SEGMENT
ComponentClass: PipingNetworkSegment
ComponentClassURI: http://data.posccaesar.org/rdl/RDS267704

ColorCode¶
Attribute (data)
The color code of the PipingNetworkSegment, represented as a string.
Multiplicity: 0..1
Type: NullableString
Implementation in Proteus Schema
The attribute is implemented as a DEXPI generic attribute for string values.
RDL reference: COLOR CODE ASSIGNMENT CLASS

</GenericAttributes>

</PipingNetworkSegment>
Connections¶
Attribute (composition)
The connections of the PipingNetworkSegment.
Implementation in Proteus Schema
In case the PipingConnection is a Pipe, the corresponding <CenterLine> element is a child of the <PipingNetworkSegment>. Two <CenterLine> elements must be separated by at least one element representing a PipingNetworkSegmentItem, e.g., a <PipingComponent>, in order to implement two Pipes; otherwise, the two <CenterLine> elements would represent a single Pipe whose graphical representation contains a visual “gap”, e.g., when another Pipe crosses.
In case the PipingConnection is a DirectPipingConnection, there is no corresponding Proteus element. A DirectPipingConnection is rather given implicitly, e.g., by two successive <PipingComponent> elements (see Proteus Schema Implementation of DirectPipingConnection).
Example
As the value type PipingConnection is abstract, we consider Pipe as an arbitrary concrete subclass.

SourceNode¶
Attribute (reference)
The PipingNode at which the PipingNetworkSegment starts.
Implementation in Proteus Schema
The SourceNode is given by means of the FromNode XML attribute of the <Connection> element in the <PipingNetworkSegment> element. The value of the FromNode XML attribute is an integer. It refers to the zero-based index of the <Node> element within the <ConnectionPoints> element associated with the owner of the PipingNode. The owner itself is given by means of the FromID XML attribute of the <Connection> element (see Proteus Schema Implementation of SourceItem).
For details, see Proteus P&ID File Specification. Note that in certain cases, Proteus Schema allows to omit the FromNode attribute when it is clear from the context.
Example
Implementation in Proteus Schema
The XML fragment demonstrates the case that the SourceNode belongs to a PipeTee in another PipingNetworkSegment.

TargetItem¶
Attribute (reference)
The item at which the PipingNetworkSegment ends.
Implementation in Proteus Schema
The TargetItem is given by means of the ToID XML attribute of the <Connection> element in the <PipingNetworkSegment> element. The value of the ToID XML attribute is the XML ID of the XML element corresponding to the TargetItem, e.g., a Nozzle or a PipingComponent.
Example
Implementation in Proteus Schema
The XML fragment demonstrates the case that the TargetItem of the <PipingNetworkSegment> is a Nozzle of some Equipment item.
<PipingNetworkSegment
ID="pipingNetworkSegment1"
ComponentClass="PipingNetworkSegment"
ComponentClassURI="http://data.posccaesar.org/rdl/RDS267704"
...>
...
<Connection ToID="nozzle1" ...>
...
</PipingNetworkSegment>
...
<Equipment ...>
...
<Nozzle
ID="nozzle1"
ComponentClass="Nozzle"
ComponentClassURI="http://data.posccaesar.org/rdl/RDS415214"
...>
...
</Nozzle>
...
</Equipment>
TargetNode¶
Attribute (reference)
The Node at which the PipingNetworkSegment ends.
Implementation in Proteus Schema
The TargetNode is given by means of the ToNode XML attribute of the <Connection> element in the <PipingNetworkSegment> element. The value of the ToNode XML attribute is an integer. It refers to the zero-based index of the <Node> element within the <ConnectionPoints> element associated with the owner of the PipingNode. The owner itself is given by means of the ToID XML attribute of the <Connection> element (see Proteus Schema Implementation of TargetItem).
For details, see Proteus P&ID File Specification. Note that in certain cases, Proteus Schema allows to omit the ToNode attribute when it is clear from the context.
Example
Implementation in Proteus Schema
The XML fragment demonstrates the case that the TargetNode belongs to a PipeTee in another PipingNetworkSegment.
