A Novel Method for Simulation Model Generation of Production Systems Using PLC Sensor and Actuator State Monitoring

Publication Name: Journal of Sensor and Actuator Networks

Publication Date: 2025-06-01

Volume: 14

Issue: 3

Page Range: Unknown

Description:

This article proposes and validates a novel methodology for automated simulation model generation of production systems based on monitoring sensors and actuator states controlled by Programmable Logic Controllers during regular operations. Although conventional Discrete Event Simulation is essential for material flow analysis and digital experimentation in Industry 4.0, it remains a resource-intensive and time-consuming endeavor—especially for small and medium-sized enterprises. The approach introduced in this research eliminates the need for prior system knowledge, physical inspection, or modification of existing control logic, thereby reducing human involvement and streamlining the model development process. The results confirm that essential structural and operational parameters—such as process routing, operation durations, and resource allocation logic—can be accurately inferred from runtime data. The proposed approach addresses the challenge of simulation model obsolescence caused by evolving automation and shifting production requirements. It offers a practical and scalable solution for maintaining up-to-date digital representations of manufacturing systems and provides a foundation for further extensions into Digital Shadow and Digital Twin applications.

A Framework for Effective Virtual Commissioning: Guiding Principles for Seamless System Integration

Publication Name: Journal of Manufacturing and Materials Processing

Publication Date: 2024-08-01

Volume: 8

Issue: 4

Page Range: Unknown

Description:

Virtual commissioning (VC), defined as the simulation and testing of systems in a virtual environment before physical implementation, plays a key role in addressing the challenges of integrating and validating complex systems efficiently and effectively. This paper focuses on the topic of virtual commissioning, summarizing and organizing existing research in the field. The paper provides a comprehensive overview of various design methods and technologies currently in use. A case study of virtual commissioning is also presented within the area of the Cyber-Physical Manufacturing Systems Laboratory of the Széchenyi István University, detailing the solution steps taken. Drawing on both research and practical experience, the paper proposes a novel framework to support virtual commissioning design, referred to as the “Virtual Commissioning House” (VCH). The methodology is evaluated through comparisons with existing virtual commissioning solutions, demonstrating its effectiveness.

Information Basis of Digital Twins: A Quantifiable Metric for Spatio-Temporal Expressivity

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2023-01-01

Volume: 20

Issue: 6

Page Range: 151-171

Description:

This paper focuses on the concept of Digital Twins and the characterization of Digital Twins in terms of the spatio-temporal extent of the information based on which they operate. Following an in-depth literature review, we observe that even when Digital Twins (and variations of this concept) are qualified in terms of ‘levels of information integration’, strictly quantifiable metrics are rarely applied. To fill this gap, we propose the term ‘information basis’, which highlights the quantifiable extent of events occurring in space and time which have an influence on the functionality of the Digital Twin. Following a discussion on the implications of this term, we present an example Digital Twin and discuss how its different alternative implementations would fall on different points of the newly introduced information basis spectrum.

A Digital Twin Case Study Exhibiting Bi-Directional Communication and Control

Publication Name: 2022 IEEE 1st International Conference on Internet of Digital Reality Iod 2022

Publication Date: 2022-01-01

Volume: Unknown

Issue: Unknown

Page Range: 105-106

Description:

This paper focuses on the concept of Digital Twins and a Digital Twin based case study. The first part of the paper provides a discussion on digital twins and categorizations thereof, based on their role in specific applications, the directionality of communication in which they are involved, and levels of integration based on this communication. The second part of the paper outlines a case study of a digital twin with bi-directional communication based on a near-real-time standard protocol involing real interventions in a physical system. The system underlying the case study was developed at Széchenyi István University in Györ, Hungary.

Transformation of traditional assembly lines into interoperable CPPS for MES: An OPC UA enabled scenario

Publication Name: Procedia Manufacturing

Publication Date: 2020-01-01

Volume: 54

Issue: Unknown

Page Range: 118-123

Description:

The exploitation of I4.0 paradigm requires the availability of adequate information across all engineering and production value chains, which is the result of aggregation and fusion of data from various heterogeneous sources, often under real-time conditions. On the one hand, this comprises a challenge for the provision of an efficient, secure and dependable information management infrastructure. On the other hand, system architects must find solutions to assure interoperability on both syntactical and semantic level with reasonable engineering costs. In this paper authors present the research outcomes related to the conceptualization of a generalized information model and a service architecture, for the transformation and integration of typical third-party, stand-alone industrial equipment-FESTO prolog-factory in the specific-into an OPC UA enhanced, Industry 4.0 interoperable CPPS for new generations of Manufacturing Execution Systems. Aim of the discussed approach is to define basic but general guidelines of applicability for the definition, modelling and provision of standardized, Industry 4.0 compliant, CPPS-based industrial services, starting off from a typical legacy industrial environment.

The role of digital twin in a cyber-physical production environment with prescriptive learning

Publication Name: 17th International Conference on Modeling and Applied Simulation Mas 2018

Publication Date: 2018-01-01

Issue: Unknown

Page Range: 180-184

Description:

In this paper, we introduce the establishing of digital twins for cyber-physical production systems. Using industrial PLC network and a discrete event simulation tool a live and interactive connection is made between the physical and cyber world. Based on this achievement a modified proactive framework with prescriptive simulation will be presented.
