Data exchange plays a vital role in digital twin design, serving as the lifeblood of the entire system. Digital twins are virtual replicas of physical assets or systems that enable real-time monitoring, analysis, and simulation. To accurately model and simulate the behaviour of the physical counterpart, a continuous flow of data is essential. Data exchange facilitates the transfer of information between the physical asset and its digital twin, enabling real-time monitoring of sensor data, operational parameters, and environmental conditions. This exchange allows the digital twin to reflect the current state of the physical asset, enabling predictive maintenance, performance optimization, and scenario testing. Additionally, data exchange facilitates collaboration and integration with other systems, such as enterprise resource planning (ERP) or supply chain management, further enhancing the capabilities and value of digital twins. Ultimately, data exchange serves as the foundation for effective decision-making, enabling informed actions, and driving operational efficiencies in various industries.
