ISA-95-4 Job Control - 6 ISA-95 Data Representation Model

The OPC UA ISA-95 Information Model is a representation of the ISA-95 data model in OPC Methods, ObjectTypes, VariableTypes, DataTypes and ReferenceTypes.

This model generates standard types. All ISA-95 types will be defined in their own namespace and will begin with “ISA95”

The following conventions apply to ObjectType, VariableType and DataType naming:

All ObjectTypes include “ObjectType” as part of the name
All DataTypes that are structures include “DataType” as part of the name, this is to be able to differentiate them from any VariableTypes that will just end in Type.
All enumerations will end in “Enum”, to clearly identify that it is an enumeration.
All base DataTypes (int32, float, …) used in the OPC UA server will be those defined in OPC UA, see OPC 10000-6 for more detail on the representation of the datatypes.
