5.8.2 Encoding Rules for different kinds of DataTypes

should be known to all OPC UA products. Examples of Built-in DataTypes are Int32 (see 8.26 ) and Double (see 8.12 ). Simple DataTypes are subtypes of the Built-in DataTypes ... DataTypes that represent discrete sets of named values. Enumerations are always encoded as Int32 on the wire as defined in OPC 10000-6 . Enumeration DataTypes inherit directly or indirectly from
