METHOD AND APPARATUS FOR INTERCHANGING DATA BETWEEN TWO DEVICES IN AN AUTOMATION NETWORK

摘要

A method for interchanging data between two devices in a network which utilizes a communication protocol with an interface based on the OPC-UA standard to interchange the data, wherein the communication protocol includes a priority allocation function which can allocate to the data at least two different priority values, and the data are interchanged based on the allocated priority values, such that the data interchangeable between the two devices in a predetermined period of time with a prescribed probability.
