User-Network Interface
A deterministic data transfer between two devices can only work if the communication
requirements of the devices match the resources available in the network. A suitable
transmission path must be made available for time-critical OPC UA data. The User Network
Interface (UNI) automatically takes on this decentralized coordination task. The special
advantage for users is that a system is not required for the central configuration.
