Overview

The function blocks of the Tc3_IoTCommunicator PLC library can be used to realize data exchange between the local TwinCAT PLC and a mobile end device (smart device) via an MQTT message broker. Symbols can be sent and received. Messages can be stored on the broker and read or deleted via the smart device. To this end, the TwinCAT IoT Communicator app must be installed and running on the mobile end device.

The TwinCAT IoT Communicator app can be downloaded free of charge from the Apple AppStore or Google PlayStore.
