When modeling industrial systems with OPC UA, the debate between composition and inheritance often arises In object modeling, composition frequently proves to be a more flexible and powerful alternative to derivation (inheritance). While inheritance can result in complex and rigid hierarchies, composition facilitates the creation of flexible and reusable components.
Finite State machines can be easily defined with the Sterfive opcua modeler.
Creating OPCUA models is a difficult task that requires a good understanding of the OPCUA modeling paradigms and good knowledge of conventions and best practices. Extending or creating a new ObjectType or DataType has always been tedious and time-consuming. Name each node right, and organize the nodes within the context of an existing companion specification is always challenging. Most of the time, this modeling exercise requires deep expertise in this field.
