OPC Client for MQTT: Get Your OPC DA Data to the Cloud in Seconds

Yes, the software supports multi-broker configurations. You can publish different data sets to separate MQTT brokers or implement redundancy by publishing to both primary and backup brokers. This ensures high availability and supports diverse cloud architecture requirements. 

The OPC Client for MQTT includes sophisticated buffering mechanisms that store data locally during network outages. When connectivity is restored, buffered data is automatically published to the MQTT broker, ensuring zero data loss. Buffer size and retention policies are fully configurable. 

Absolutely. The solution supports TLS/SSL encryption for secure MQTT communications, username/password authentication, and certificate-based authentication. All data transmitted between OPC servers and MQTT brokers can be encrypted end-to-end, meeting industrial cybersecurity standards. 

The OPC Client for MQTT works with any MQTT-compliant broker, including Azure IoT Hub, AWS IoT Core, Google Cloud IoT Core, IBM Watson IoT, HiveMQ, Mosquitto, and more. We provide specific tutorials for popular platforms like Azure IoT Hub to accelerate your deployment.
