“…As stated in [ 20 ] and [ 21 ], OPC UA and TSN are foreseen also to the field level, respectively. The study in [ 22 ] emphasized the real-time issue and the applicability of the concept on the field devices, but it provides only simulations. In the case of OPC UA publish–subscribe mechanism, the integration of TSN technology represents the next step in achieving real-time behavior, increased efficiency, and quality of service.…”

The Open Platform Communication Unified Architecture (OPC UA) protocol is a key enabler of Industry 4.0 and Industrial Internet of Things (IIoT). OPC UA is already accepted by the industry and its presence is expected to reach more and more fields, applications, and hierarchical levels. Advances within the latest specifications are providing the opportunity to extend the capabilities and the applicability of the protocol, targeting better performances in terms of data volumes, speed, availability, footprint, and security. Continuing previous researches focusing on the publish–subscribe (pub/sub) mechanism and real-time constraints, the current study aims to consider higher data-volumes, approach the multi-channel User Datagram Protocol (UDP)-based communication, and analyze the robustness of the developed mechanism in the context of long-term data transmission. Consequently, the research proposes to extend the applicability of the OPC UA in the context of image transmission. Although highly needed, the image transmission after processing is currently beyond the reach of OPC UA or other legacy industrial protocols, being considered as a separate fraction in the industrial environment. The concept and developments are applied considering both the end-of-line industrial manufacturing process in the automotive sector and the car-to-infrastructure communication. Without special hardware constraints, the obtained results are proven to be appreciable, opening various future perspectives for image transmission using OPC UA.

“…In the industrial domain, TSN is represented in many works [ 8 , 10 , 11 , 12 , 15 , 16 , 17 , 32 , 37 , 38 , 39 ]. Since TSN is only represented at the lower layers of the OSI model, it is often considered together with a high-level protocol.…”

“…The best-known representative in this case is OPC UA. Several publications regard the combination of TSN and OPC UA as future real-time communication candidate at the field level [ 10 , 11 , 15 , 16 , 32 , 37 ]. TSN offers a variety of mechanisms such as EEE 802.1Qbv, IEEE 802.1Qch, IEEE 802.1Qcr, and IEEE 802.1Qbu to guarantee timely response [ 37 ].…”

“…The combination of TSN and OPC UA enables flexible and deterministic communication for a wide range of devices from different manufacturers lowering the configuration overhead. Thus, it is not only interesting for industrial automation [ 10 , 12 , 15 , 16 , 17 ], but also for other application domains like the automotive [ 18 , 19 ] and railway industry [ 20 ].…”

The transportation industry is facing major challenges that come along with innovative trends like autonomous driving. Due to the growing amount of network participants, smart sensors, and mixed-critical data, scalability and interoperability have become key factors of cost-efficient vehicle engineering. One solution to overcome these challenges is the AUTOSAR Adaptive software platform. Its service-oriented communication methodology allows a standardized data exchange that is not bound to a specific middleware protocol. OPC UA is a communication standard that is well-established in modern industrial automation. In addition to its Client–Server communication pattern, the newly released Publish–Subscribe (PubSub) architecture promotes scalability. PubSub is designed to work in conjunction with Time-Sensitive Networking (TSN), a collection of standards that add real-time aspects to standard Ethernet networks. TSN allows services with different requirements to share a single physical network. In this paper, we specify an integration approach of AUTOSAR Adaptive, OPC UA, and TSN. It combines the benefits of these three technologies to provide deterministic high-speed communication. Our main contribution is the architecture for the binding between Adaptive Platform and OPC UA. With a prototypical implementation, we prove that a combination of OPC UA Client–Server and PubSub qualifies as a middleware solution for service-oriented communication in AUTOSAR.

“…The alwayschanging interconnection between devices and applications requires a dynamic configuration. The authors in Panda et al [26] simulated OPC UA field level communication by using OPC UA PubSub, best-effort IP-based communication between OPC UA servers, and a shared information model. In almost all current research related to OPC UA PubSub the open-source OPC UA project open62541 was chosen.…”

Industrial automation is changing towards higher integration and seamless communication. A stepping stone is end-to-end real-time machine-to-machine communication, now becoming feasible with technologies such as time-sensitive networking (TSN) and OPC Unified Architecture (OPC UA) publishsubscribe. While TSN takes care of communication, the OPC UA stack's execution time behavior remains unknown. This paper highlights experiences made while adjusting the OPC UA subscriber of the open62541 stack for worst-case execution time (WCET) analysis. Two directly connected time-predictable T-CREST platforms hosting the publisher and subscriber delivered end-to-end timing measures validating the WCET estimates. The paper concludes by outlining further research with several timepredictable publishers and subscribers.
