Got an IoT2040 from Siemens. It is Arduino compatible and runs on Yocto Linux. ETM managed to compile the SCADA System WinCC Open Architecture on it, additionally we used a MQTT server (mosquitto), Node-Red with MQTT, and a MQTT Driver for WinCC OA written in Java… runs well. Just connected a simple LED and a Button with Node-Red, those can now be controlled by WinCC OA. Because WinCC OA runs on it, it can be used to connect a wide range of different devices (a lot of drivers are available for WinCC OA).

Perfect as an Edge device to collect data from the field… Industrial IoT with Siemens!
