3062 +This chapter describes how to use various MQTT communication protocols. Users can publish messages to the MQTT server and subscribe to topics from the server.
3063 +
3064 +Some HMI models support a multi-instance MQTT client architecture, allowing the HMI device to act as a client and connect to multiple independent MQTT Brokers (servers). With this function, messages can be published to different servers without interference. It breaks the limit of a single data channel, supports distributed data reporting, multi-cloud collaboration, and integration of heterogeneous systems, enabling "one-device multi-send" directly on the device side. In addition, different network adapters can be selected to bind data flows and enhance data security.
3065 +
3066 +Each MQTT connection instance supports independent operating status control and complete parameter configurations, ensuring high availability and flexibility of communication in complex network environments. In addition to enabling or disabling each server in project configuration, users can dynamically adjust the communication status of specific channels by operating registers according to service requirements or network conditions, without device restart or interference to other channels.

3076 +Network adapter: Click the button on the right and select a specified network adapter from the drop-down list. If [Default] is selected, the system will automatically use an available network port for connection. Multiple servers can share the same network adapter.
