MQTT protocol sets new standard for connectivity and security

21-02-2024 | Softing | Industrial

The Secure Integration Server (SIS) from Softing Industrial now supports the MQTT protocol. This improves connectivity and security for data integration in IT/OT cloud applications. MQTT delivers enhanced security and connectivity features for Secure Integration Server.

The SIS provides a structured solution for complex server architectures. It combines various OPC UA servers at the automation level with their associated address spaces. This allows a standardised mapping of these address spaces in accordance with the OPC UA Companion Specification. The data supplied in this way is then obtainable 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), making data integration more secure and flexible. The most significant benefits include:

MQTT Publisher & Subscriber: allows bi-directional data traffic for efficient communication. MQTT Authentication Settings: Ensure 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. Various Publishing Modes and 'Dynamic Payload': Guarantee high flexibility for different data requirements. Up to 25 MQTT Connections: Ensure seamless communication and a scalable solution.

Product manager Andreas Röck commented on this development: "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."
