Abstract:
1. A method for interchanging data between two devices of a network, said method utilizing a communication protocol having an interface conforming to an Object Linking and Embedding for Process Control Unified Architecture (OPC-UA) standard to interchange the data, the method comprising: assigning at least two different priority values to the data via a priority allocation function of the communication protocol; and interchanging the data in accordance with the OPC-UA standard as a function of the assigned at least two different priority values such that the data is interchangeable in accordance with the OPC-UA standard between the two devices within a predetermined time period with a predefined probability; wherein the priority allocation function assigns a first priority value to a first type of data and a second priority value to a second type of data; and wherein, for a predefinable network structure via which the interchange of the data in accordance with the OPC-UA standard between the two devices executes, the data of the second type is transmitted based on the assigned priority values in an event of a collision between the first type of data and the second type of data.
