- Add logic to process the received MQTT message: in this reference project a check is executed if the subscription that triggered the callback method matches the subscription configured in the *MqttInit* method. In that method the subscription topic is automatically concatinated with the function block name. For more in depth details study the *PublishReceived* and *MqttInit* methods of every MQTT function block in the reference project.

MQTT subscription topic is a concatenation of the subscribe prefix variable, function block name, node number and register number. For example, topic `Devices/PLC/House/In/RS485/FB_RS485_DUCO_DUCOBOX_MQTT/1/write/0` with payload `30` will set the 'Target value (%)' parameter for node 1 (which in this case represents the entire system). Go through the DUCO modbus register documentation linked above for a deeper understanding.

Upon a succesfull write operation the received payload will be published on the 'Out' topic. Continuing with the example above this will result in a payload `30` to be published on topic `Devices/PLC/House/Out/RS485/FB_RS485_DUCO_DUCOBOX_MQTT/1/write/0`.
