OPC UA data type |
Stream data type |
|---|---|
|
Enumeration defined in OpcUa type library |
<Enumeration name> + "Enum" |
|
TwoStateDiscreteType |
<FalseState> + <TrueState> + "Enum" |
|
MultiStateDiscreteType |
<Hash of EnumStrings names> + "Enum" |
|
MultiStateValueDiscreteType |
<Hash of EnumValues names and integer values> + "Enum" |
For more information on enumeration variables, see Enumeration types.
In earlier versions, each Enumeration variable not defined in the OpcUa type library had a unique enum data type using the NodeId + "Enum" as the type name.
