## Inheritance

[Object](https://learn.microsoft.com/dotnet/api/system.object) → [OpcNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnode/) → [OpcInstanceNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcinstancenode/) → [OpcVariableNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvariablenode/) → [OpcDataVariableNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcdatavariablenode/) → [OpcDataItemNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcdataitemnode/) → [OpcDiscreteItemNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcdiscreteitemnode/) → [OpcMultiStateValueDiscreteNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcmultistatevaluediscretenode/) → **OpcMultiStateValueDiscreteNode&lt;T&gt;**

## Remarks

The multi state discrete node is a specialization of the [OpcDiscreteItemNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcdiscreteitemnode/) 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 [MultiStateValueDiscrete](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcvariabletype/#multistatevaluediscrete).
