Development of a Novel Methodology to Retrofit Legacy Systems in the Context of Industry 4.0

Abstract

This research work aims to develop a comprehensive methodology for retrofitting legacy industrial automation systems, encompassing hardware and software updates, testing, and validations, to ensure that the system aligns with current and future needs. The proposed methodology not only addresses the technical aspects but also takes into account the integration of emerging technologies such as the Internet of Things (IoT), cyber-physical systems, cloud computing, and digital twins. The main goal of the retrofitting process is to enhance the efficiency, integration, security, and interoperability of the legacy system, enabling it to remain competitive in the long term. Legacy systems may require retrofitting due to various reasons, including incompatibility with new devices or technologies, inability to meet the current needs of the manufacturing process, vulnerability to security threats, or non-compliance with current industry standards and regulations. Through the proposed methodology, step-by-step guidance will be provided, enabling organizations to successfully update their legacy systems using retrofitting techniques and capitalize on the advantages offered by Industry 4.0.
