<div class="api-signature" data-lang="csharp">

```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet

```

</div>

**Property value**

The [OpcNodeId](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeid/) of the type node from that this [OpcInstanceNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.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](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcdataitemnode/members#defaulttypedefinitionid)

### EngineeringUnit

Gets or sets the engineering unit information which specifies the unit of the value attribute of the [OpcAnalogUnitNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/).

<div class="api-signature" data-lang="csharp">

```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Property EngineeringUnit As OpcEngineeringUnitInfo
```

</div>

**Property value**

[OpcEngineeringUnitInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcengineeringunitinfo/)

An instance of the [OpcEngineeringUnitInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcengineeringunitinfo/) class which provides the information of the unit used to scale the value attribute of the [OpcAnalogUnitNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.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](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/members#engineeringunit) property is strongly advised.

### EngineeringUnitNode

Gets the [OpcEngineeringUnitInfoPropertyNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcengineeringunitinfopropertynode/) of the [EngineeringUnit](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/members#engineeringunit) property.

### EngineeringUnitRange

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

<div class="api-signature" data-lang="csharp">

```csharp
public OpcValueRange EngineeringUnitRange { get; set; }
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Property EngineeringUnitRange As OpcValueRange
```

</div>

**Property value**

[OpcValueRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvaluerange/)

An instance of the [OpcValueRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.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](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvaluerangepropertynode/) of the [EngineeringUnitRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/members#engineeringunitrange) property.

<div class="api-signature" data-lang="csharp">

```csharp
public OpcValueRange InstrumentRange { get; set; }
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet

```

</div>

**Property value**

[OpcValueRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvaluerange/)

An instance of the [OpcValueRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.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](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/).

**Remarks**

Although defined as optional, it is strongly recommended for Servers to support this property. Without an [InstrumentRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/members#instrumentrange) being provided, Clients will commonly assume the full range according to the [DataType](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvariablenode/members#datatype) of the [OpcAnalogUnitNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/).

### InstrumentRangeNode

Gets the [OpcValueRangePropertyNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvaluerangepropertynode/) of the [InstrumentRange](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode/members#instrumentrange) property.
