Softing Industrial has integrated the MQTT protocol into its Secure Integration Server (SIS). The integration of MQTT improves connectivity and security for data integration in IT/OT cloud applications.

The Secure Integration Server (SIS) is designed to offer a structured solution for complex server architectures. It combines various OPC UA servers at the automation level with their associated address spaces. This enables a standardised mapping of these address spaces in accordance with the OPC UA Companion Specification. The data provided in this way is then available for IoT cloud applications via a standardised OPC UA interface.

The latest version of the SIS, V1.30, integrates the MQTT protocol (versions 3 and 5).

Benefits include: MQTT Publisher & Subscriber, enabling bi-directional data traffic for efficient communication; MQTT Authentication Settings, ensuring security and identification between clients and brokers through various authentication methods such as anonymous, username or certificates; MQTT Store&Forward Function: Protects against data loss; up to 25 MQTT Connections proving scalability.

Product Manager Andreas Röck said: “The integration of the MQTT protocol into our Secure Integration Server underlines our commitment to advanced solutions in industrial data integration. The enhanced security and connectivity features open up new possibilities for efficient and reliable data transmission for our customers.”
