Easy and secure transfer of process data to mobile end devices

The TwinCAT IoT Communicator makes it easy for PLCs to communicate with mobile devices by connecting the TwinCAT controller directly and securely to a messaging service through TLS encryption. For smartphone and tablet users, the associated IoT Communicator App ensures that process data can be represented on all mobile devices in a clear overview. Alarms are sent to the device as push messages.

The TwinCAT 3 IoT Communicator exchanges data using a publish/subscribe mechanism. Since no special firewall settings are needed, integration into an existing IT network is easy. Information is exchanged via a message broker that uses the standardised MQTT protocol and acts as a central messaging service in a cloud or local network. A high level of communication security is guaranteed by proven TLS encryption (up to version 1.2).
