A drive control is to be operated via a cloud-based control service. The process data (process events) are updated cyclically for the drives at 100 µs intervals. The cloud controller must react to each process event in time and trigger an action. The delay time in the local TSN network is 10 µs. In the cloud, 50 µs are required for processing. Data transmission to the cloud uses a WAN with copper and fiber optic lines. The signal propagation time in these lines is approximately 200,000 km/s.
