The Cumulocity Connector App is in terms of Internet of Things (IoT) a device agent, since it is connecting PLCnext devices produced by Phoenix Contact with the Cumulocity IoT platform which is a product from Software AG. Therefore, on the one hand the App will communicate over the device specific protocol with the PLCnext device and on the other hand the App will forward and fetch data over HTTPS with Cumulocity. For exchanging data with Cumulocity the Cumulocity data model must be used and therefore, the App will transform the device specific data.
