In this guide Modbus TCP master MQTT Gateway function will be configured with two different types of MQTT Brokers. First using third party MQTT Broker services (in this example ''Flespi.io''). Second using RUT240 router as MQTT Broker. Two RUT955 routers will be used as Modbus TCP Master and Slave, and PC acts as MQTT Publisher and Subscriber.
