One of the core ideas of Industry 4.0 has been the use of Digital Twin Networks (DTN). DTN facilitates the co-evolution of real and virtual things through the use of DT modelling, interactions, computation, and information analysis systems. The DT simulates product lifecycles to forecast and optimizes manufacturing systems and component behaviour. Industry and Academia have been developing Digital Twin (DT) technology for real-time remote monitoring and control, transport risk assessment, and intelligent scheduling in the smart industry. This study aims to design and simulate a comprehensive digital twin model connecting three factories to a single server. It incorporates remote network control, IoT integration, advanced networking protocols, and security measures. The model utilizes the Open Shortest Path First (OSPF) routing protocol for seamless network connectivity within the interconnected factories. Authentication, authorization, and accounting (AAA) mechanisms ensure secure access and prevent unauthorized entry. The Digital Twin Model is simulated using Cisco Packet Tracer, validating its functionality in network connectivity, security, remote control, and motor efficiency monitoring. The results demonstrate the successful integration and operation of the model in smart industries. The networked factories exhibit improved operational efficiency, enhanced security, and proactive maintenance.
