When we talk about I-IoT, we need a real device to acquire data from a real case. Predix provides its own hardware device and a simple software gateway called Predix Machine. The Predix Machine can be downloaded and installed locally to acquire data from  https://www.predix.io/services/service.html?id=1185. We need to configure the data adapter to get data through modbus, OPC-UA, or MQTT, and we need to configure the data river so that we can send data on the cloud. The configuration files are located in <PredixMachine HOME>/configuration/machine. Alternatively, you can get the Predix developer kit from Predix's official site.
