<Item> – OPC UA Object(s) that are part of the Object Type.
<Connection> – OPC UA Object(s) that are part of the Object Type.
FlowDirectionSpecialization – A specialization indicating if the PipingNetworkSegment enables dual flow or not.
HeatTracingTypeSpecialization – A specialization indicating the heat tracing type related to the PipingNetworkSegment.
PrimarySecondaryPipingNetworkSegmentSpecialization – A specialization indicating whether the PipingNetworkSegment is a primary or secondary PipingNetworkSegment.
InsulationThickness – The insulation thickness of the PipingNetworkSegment.
LowerLimitHeatTracingTemperature – The temperature that a heat tracing system must ensure for the PipingNetworkSegment.
SiphonSpecialization – A specialization indicating if the PipingNetworkSegment is a siphon or not.
PressureTestCircuitNumberAssignmentClass – The number of the pressure test circuit of the PipingNetworkSegment.
InsulationTypeAssignmentClass – The identification code for the insulation type related to the PipingNetworkSegment. So far, DEXPI does not define restrictions for valid values.
ColorCodeAssignmentClass – The color code of the PipingNetworkSegment, represented as a string.
PipingClassCodeAssignmentClass – The identification code of the piping class of the PipingNetworkSegment. So far, DEXPI does not define restrictions for valid values.
NominalDiameterTypeRepresentationAssignmentClass – A readable representation of the type of the nominal diameter of the PipingNetworkSegment. The purpose of this value is to give a textual representation of the nominal diameter to be used in the graphics of a PID.
SlopeSpecialization – A specialization indicating if the PipingNetworkSegment is sloped or not.
NominalDiameterStandardSpecialization – The nominal diameter of the PipingNetworkSegment, given as a reference to a nominal diameter standard and value.
SegmentNumberAssignmentClass – The segment number of a PipingNetworkSegment. Values are typically (but not necessarily) string representations of numbers with a prefix.
OperatingTemperature – The operating temperature of the PipingNetworkSegment.
HeatTracingTypeAssignmentClass – The heat tracing type related to the PipingNetworkSegment, represented as a string.
JacketedPipeSpecialization – A specialization indicating whether the PipingNetworkSegment is jacketed.
FluidCodeAssignmentClass – The identification code of the fluid related to the PipingNetworkSegment. So far, DEXPI does not define restrictions for valid values.
Inclination – The inclination (slope) of the PipingNetworkSegment in percent.
NominalDiameterNumericalValueRepresentationAssignmentClass – A readable representation of the numerical value of the nominal diameter of the PipingNetworkSegment. The purpose of this value is to give a textual representation of the nominal diameter to be used in the graphics of a PID.
NominalDiameterRepresentationAssignmentClass – A readable representation of the nominal diameter of the PipingNetworkSegment. The purpose of this value is to give a textual representation of the nominal diameter to be used in the graphics of a PID.
BasfLineClassAssignmentClass – The BASF line class of the PipingNetworkSegment, represented as a string. Note: This attribute has been included as an example for a company-specific attribute. It should actually be identified by a company-specific RDL reference. As there is currently no BASF RDL, the DEXPI RDL is used.
OnHoldSpecialization – A specialization indicating if the PipingNetworkSegment is on hold or not.
