## Derived types

- [OpcAnalogUnitNode&lt;T&gt;](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcanalogunitnode-1/)

## Remarks

The analog unit node is a specialization of the [OpcDataItemNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcdataitemnode/) there its reference type is [HasComponent](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcreferencetype/#hascomponent) and its type definition is [AnalogUnit](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvariabletype/#analogunit).
