==MQTT Modbus Gateway==

The <b>MQTT Gateway</b> function is used to transfer Modbus data (send requests, receive responses) over MQTT. When it is enabled, the device (this {{{name}}}) subscribes to a REQUEST topic and publishes on a RESPONSE topic on a specified MQTT broker. It translates received MQTT message payload to a Modbus request and relays it to the specified Modbus TCP server.
