Data Servers
On this page
The Data Servers page controls outbound data publishing from the project. The MQTT Broker tab is available for enabling real-time data distribution to external systems.
MQTT Broker
The system includes a built-in MQTT broker. When enabled, the application publishes alarm states and tag values as MQTT messages, allowing any compatible MQTT client on the network to subscribe and receive live updates without requiring a separate broker such as Mosquitto or HiveMQ.
Check Enable to start the broker. Once running, external systems can connect directly to the server as MQTT subscribers and receive real-time data as values change.
Typical use cases include connecting to cloud analytics platforms, forwarding alarm data to notification services, integrating with Node-RED flows, or feeding data into any MQTT-capable monitoring system.
The built-in MQTT broker means external clients connect directly to the DataTalk server. There is no need to install or manage a third-party MQTT broker in your infrastructure.
