DIPUONE Virtual Commissioning uses 1:1 point simulation and full-function simulation to validate equipment models, control logic, process flow, abnormal scenarios, and acceptance standards before on-site commissioning. Through simulation models, the system can simulate device signals and control responses for sensors, valves, pumps, chillers, cooling towers, CDUs, and other equipment. It is an important way for DIPU to convert long-term project experience, process know-how, and test procedures into standardized and productized delivery capability.
