A common example of industrial IoT is to store machine data in a cloud. With the help of OPC UA Pub/Sub communication, this can be achieved without complicated connections. According to the Publish-and-Subscribe principle, for example, a machine sends production data to the broker. A connected cloud, which has subscribed to all relevant production data of a plant, receives this data from the Broker now. The cloud acts as a Subscriber, processes the data and makes it available for other devices or software in the company. At the same time, the OPC Router receives the same data from the Broker, because it is subscribed to the same topic as well. In addition to the cloud, it can now inform the sales department about a completed production and start the next order.
