In just a few simple steps both WAGO PFC100 and PFC200 Controllers can be transformed into an IoT device – using a firmware upgrade and programming an IEC application with the corresponding library. After that, status information such as Run/Stop, connection statuses, device information and variables defined in the IEC program can be sent to a cloud and visualized, for example. The customer can decide whether the controller sends data to Microsoft Azure, Amazon Web Services or IBM Bluemix. Links to third-party solutions are also feasible in the future, thanks to the standardized MQTT protocol. The data is transmitted as JSON files and the link encrypted with TLS.
The user can run the upgrade easily in the Web browser using WAGO’s Web-Based Management (WBM) System. Libraries for CODESYS 2.3 and e!COCKPIT are also included in the scope of supply. The cloud connection data are also configured using WBM. Variables that are to be transferred to the cloud can be defined in the IEC program – so the programmer is always in control.
