5.1.5 ISA95Property ToC Previous Next

ISA95Property is a concept to represent characteristics for domain specific information. Accordingly ISA-95 defines that attributes that are application or industry specific are to be modelled in terms of properties and represented in property classes in the model. ISA-95 doesn’t describe a property as an attribute in UML, but describes a property as a Class. In OPC UA it can be represented by VariableTypes and Variables (see Table 5)
