Properties

DefaultTypeDefinitionId

protected · override

Gets the default identifier which identifies the node that defines the underlying node type from that this OpcInstanceNode has been created.

protected override OpcNodeId DefaultTypeDefinitionId { get; }

Protected Overrides ReadOnly Property DefaultTypeDefinitionId As OpcNodeId

Property value

OpcNodeId

The OpcNodeId of the type node from that this OpcInstanceNode has been created from. These type node defines the typical structure of an instance node of its type definition. If there exists no specific type definition node a null reference (Nothing in Visual Basic).

Overrides

DefaultTypeDefinitionId

EngineeringUnit

Gets or sets the engineering unit information which specifies the unit of the value attribute of the OpcAnalogUnitNode.

public OpcEngineeringUnitInfo EngineeringUnit { get; set; }

Public Property EngineeringUnit As OpcEngineeringUnitInfo

Property value

OpcEngineeringUnitInfo

An instance of the OpcEngineeringUnitInfo class which provides the information of the unit used to scale the value attribute of the OpcAnalogUnitNode.

Remarks

Understanding the units of a measurement value is essential for a uniform system. In an open system in particular where servers from different cultures might be used, it is essential to know what the units of measurement are. Based on such knowledge, values can be converted if necessary before being used. Therefore, although defined as optional, support of the EngineeringUnit property is strongly advised.

EngineeringUnitNode

Gets the OpcEngineeringUnitInfoPropertyNode of the EngineeringUnit property.

public OpcEngineeringUnitInfoPropertyNode EngineeringUnitNode { get; }

Public ReadOnly Property EngineeringUnitNode As OpcEngineeringUnitInfoPropertyNode

Property value

OpcEngineeringUnitInfoPropertyNode

An instance of the OpcEngineeringUnitInfoPropertyNode class.

EngineeringUnitRange

Gets or sets the range information which applies to normal operation.

public OpcValueRange EngineeringUnitRange { get; set; }

Public Property EngineeringUnitRange As OpcValueRange

Property value

OpcValueRange

An instance of the OpcValueRange class which provides the range information of the value attribute in normal operation. This information is intended for such use as automatically scaling a bar graph display.

Remarks

Sensor or instrument failure or deactivation can result in a returned item value which is actually outside of this range. Clients must be prepared to deal with this possibility. Similarly a Client may attempt to write a value that is outside of this range back to the Server. The exact behaviour (accept, reject, clamp, etc.) in this case is Server-dependent. However, in general Server shall be prepared to handle this.

EngineeringUnitRangeNode

Gets the OpcValueRangePropertyNode of the EngineeringUnitRange property.

public OpcValueRangePropertyNode EngineeringUnitRangeNode { get; }

Public ReadOnly Property EngineeringUnitRangeNode As OpcValueRangePropertyNode

Property value

OpcValueRangePropertyNode

An instance of the OpcValueRangePropertyNode class.

InstrumentRange

Gets or sets the range information which applies to the instrumental values returned by the instrument.

public OpcValueRange InstrumentRange { get; set; }

Public Property InstrumentRange As OpcValueRange

Property value

OpcValueRange

An instance of the OpcValueRange class which provides the range information about the values provided by the unterlaying senor or instrument used to determine the value of the OpcAnalogUnitNode.

Remarks

Although defined as optional, it is strongly recommended for Servers to support this property. Without an InstrumentRange being provided, Clients will commonly assume the full range according to the DataType of the OpcAnalogUnitNode.

InstrumentRangeNode

Gets the OpcValueRangePropertyNode of the InstrumentRange property.

public OpcValueRangePropertyNode InstrumentRangeNode { get; }

Public ReadOnly Property InstrumentRangeNode As OpcValueRangePropertyNode

Property value

OpcValueRangePropertyNode

An instance of the OpcValueRangePropertyNode class.
