This Structured DataType is used to represent a human-readable representation of an Enumeration. Its elements are described in Table 30. When this type is used in an array representing human-readable representations of an enumeration, each Value shall be unique in that array.
Table 30 – EnumValueType Definition
|value||Int64||The Integer representation of an Enumeration.|
|displayName||LocalizedText||A human-readable representation of the Value of the Enumeration.|
|description||LocalizedText||A localized description of the enumeration value. This field can contain an empty string if no description is available.|
Note that the EnumValueType has been defined with an Int64 Value to meet a variety of usages. When it is used to define the string representation of an Enumeration DataType, the value range is limited to Int32, because the Enumeration DataType is a subtype of Int32. OPC 10000-8 specifies other usages where the actual value might be between 8 and 64 Bit.
