- Digital twins are a core technology for smart factories, but the high cost and complexity of existing industrial protocols like OPC-UA act as significant barriers to entry for resource-constrained small and medium-sized enterprises (SMEs). This study proposes a ‘modular lightweight architecture for discrete manufacturing process control’ to address these issues. It eliminates dependency on specific middleware, utilizing only the universal game engine Unity and standard TCP/IP socket communication. The proposed architecture functionally separates visualization (Unity server) and control logic (external client), enhancing system flexibility and minimizing communication overhead. To demonstrate the architecture's excellence, a virtual conveyor belt control experiment was conducted in a distributed LAN environment simulating an actual manufacturing site. The results confirmed stable response performance with an average round-trip time (RTT) of 25.5ms, proving it meets soft real-time control requirements. Notably, comparative analysis with an ideal localhost environment (average RTT of 15.8ms) quantitatively isolated the pure network overhead to approximately 9.7ms, objectively demonstrating the structural efficiency of the proposed architecture compared to middleware-based systems. This research presents a concrete methodology and engineering benchmark data enabling the construction of practical digital twins without expensive solutions.
