Protocol interoperability of OPC UA in ServiceOriented Architectures

• Abstract—Industrial Internet of Things covers all aspects ofnetworked intelligent manufacturing systems. This means coveringa wide array of application domains and user requirements.In such scenarios it is not feasible to define a single protocol forall situations. Hence, a multi-protocol approach is required. OPCUA has strong backing from Industry 4.0 as the protocol for theIndustrial Internet of Things. Interoperability of OPC UA hasbeen investigated in the context of migration from legacy andwith protocols such as DPWS. Additionally HTTP and CoAPhave been investigated as possible transport mediums.However, OPC UA interoperability has not been investigatedwithin a multi-protocol settings and no generic protocol translationexists. This paper proposes an OPC UA translator followingthe service translator model proposed in the Arrowhead project.Utilizing a mapping to intermediate format, it can be used alongside CoAP, HTTP and MQTT protocols.
