Abstract
The deployment of a Cyber Physical Product System (CPPS) is an important system that must be accompanied in order to build a smart factory. Based on 5G network, it is true that Smart Factories move physical factories to a digital-based cyber world through CPPS and monitor and control them intelligently and autonomously. However, the existing architectures of CPPS present only abstract modeling forms of architecture, and there was a lack of research into applying the OPC UA Framework (Open Platform Communication Unified Architecture), an international standard for data collection and exchange at smart plants, as the basic framework of CPPS. Architecture Configuration This enables the implementation of CPPS, which can include both cloud and IoT, only when field data distributed under a CPPS architecture is collected and centralized on a centralized server. In this study, a CPPS architecture was implemented through a central OPC UA server that applied the technology system to the OPC UA Framework compliant with the Central Processing UA Framework based on the 5G network, and a CPPS architecture, including how the OPC UA modeling process automatically generated CPPS logic and data processing processes, were actually implemented to study its performance and availability.
Introduction
In the Industrial 4.0, CPS refers to the same implementation of the physical world on a cyber basis using IT technologies such as IoT and ICT, and real-time delivery of realistic actions or phenomena of the physical world to the cyber world and feedback to the physical world through logical process processing. In smart factory, CPS is implemented through data collection and exchange of actual factory machines, actuators, sensors, etc. called Cyber Physical Production System (CPPS). Thus, the CPPS concept increases autonomy and flexibility in the industrial environment, ensuring high levels of integration and interoperability between manufacturing applications and systems.
CPPS is composed of various IT technologies such as IoT, Cloud, TSN and others, along with OT (Operating Technology), which operates process operation and equipment and facilities related to production process. In these diverse environments, connectivity between systems and equipment is essential. However, this is not a simple task because of this variant model, such as various installations and devices, and should incorporate a very wide range of systems and concepts. Interoperability of devices, equipment, and systems requires an integrated architecture that enables possible exchange of information. In an integrated environment, the promising OPC UA (IEC 62541) standard provides interesting features such as service-oriented architecture, data security, and reliable information models. In this study, CPPS helps to achieve two main objectives of vertical integration among various objectives: (1) data collection related to plant site processing [1] and (2) command transmission to control devices [2].
