Change is the Essence of Progress

It doesn't matter if OPC UA, MQTT, OPC Companion Specifications or NOA shaped PA-DIM data models come around the corner; they all only make sense when there is digital data coming from field devices, sensors, signals, converters, proxies etc. And what are they all connected to? A PROFINET network.
