“…Such a cyclic request is necessary because the underlying communication protocols that are used by OPC UA do not allow callback communication. The advantage of a subscription is a significant reduction in the volume of information that is exchanged via the network; the disadvantage is that the stateful communication mode is used in which all of the subscription parameters have to be stored on the server [ 33 ].…”

Dedicated fieldbuses were developed to provide temporal determinisms for industrial distributed real-time systems. In the early stages, communication systems were dedicated to a single protocol and generally supported a single service. Industrial Ethernet, which is used today, supports many concurrent services, but usually only one real-time protocol at a time. However, shop-floor communication must support a range of different traffic from messages with strict real-time requirements such as time-driven messages with process data and event-driven security messages to diagnostic messages that have more relaxed temporal requirements. Thus, it is necessary to combine different real-time protocols into one communication network. This raises many challenges, especially when the goal is to use wireless communication. There is no research work on that area and this paper attempts to fill in that gap. It is a result of some experiments that were conducted while connecting a Collaborative Robot CoBotAGV with a production station for which two real-time protocols, Profinet and OPC UA, had to be combined into one wireless network interface. The first protocol was for the exchange of processing data, while the latter integrated the vehicle with Manufacturing Execution System (MES) and Transport Management System (TMS). The paper presents the real-time capabilities of such a combination—an achievable communication cycle and jitter.

“…The information is organised in an object-oriented manner in which the structure and meaning of each data item are determined by the relevant type definitions. The basic OPC UA types are defined by the standard and are used to arrange the variables, objects, data and references that show the relationships between the information items [27]. The model can be easily expanded according to the requirements of the application by applying the inheritance mechanism.…”

The ongoing changes in manufacturing require that new information models for industrial computer systems be developed and applied. This paper describes a concept for the material model as a ''digital twin'' for producing highly customised, smart electronic devices. The scope of the research is the transformation of the models that are typical for the currently used automation pyramid approach to Reference Architecture Models for Industry 4.0 (RAMI4.0). The ISA95 standard is used as the modelling tool and Open Production Connectivity Unified Architecture (OPC UA) as the communication middleware. The presented use case focuses on a rework operation that is performed during the short series production of highly customised electronic devices that are produced by the Aiut company. The paper focuses on the transformation from the static architecture of Manufacturing Execution Systems to flexible and dynamic information models. INDEX TERMS Common information model (computing), computer integrated manufacturing, flexible manufacturing systems, intelligent manufacturing systems.
