A Digital Twin is a virtual double of a product , a machine, a process or of a complete production facility. Digital twins not only enable products to be conceived, simulated, and manufactured faster than in the past, but also to be designed with a view to improved economy, performance, robustness or environmental compatibility. Benefits: Shorter time to production. Quicker change cycles. Achieve a high quality PLC Code. Optimized performance of the machine or system. Reduced cost of production failures & downtime. Reduced cost of physical prototypes. Boost design efficiency.
