Modbus to MQTT Converter

SCADADroid® functions as a gateway Modbus TCP/RTU to MQTT converter. Any device acting as a Modbus master or slave with an Ethernet or serial connection can be connected to SCADADroid® which then can be configured to convert to MQTT tags with no programming. These MQTT tags will publish to any MQTT server, or use Reonix Automation’s own MQTT broker hosting services.

 

SCADADroid® models recommended as a MQTT converter are SCADADroid® R2+NM or the R2A+NM (with hardwired analog inputs and serial port). For further functionality and access to a cellular network instead of hardwired Ethernet, the SCADADroid® R2+ and R2A+ will also seamlessly convert from Modbus TCP to MQTT.

SCADADroid® MQTT provides cloud-based messaging, much like Facebook Messenger App

MQTT handles information by having a client (a client being a device with the authority to both publish and subscribe) subscribe to a topic through the MQTT broker. At an event, the publisher (i.e. the SCADADroid®) sends a message to the cloud-based broker with a Topic included in the string. The broker will then push the message out to all the clients that have subscribed to that topic. This message can be sent to as many phones or computers that have subscribed to the desired topic, from the Broker as appropriately prioritized.

SCADADroid® MQTT

Internet of Things protocol can optimize cellular data transmission via MQTT’s publish-subscribe messaging system, transferring rationed data at critical times by way of a message broker.

 

The two-way communication of MQTT enables the publisher to send data to the broker, which can then be pushed to the subscriber worry-free, rather than having the subscriber poll the publisher constantly. This protocol dramatically reduces data usage on a cell plan.  The client can subscribe to tagged values from multiple SCADADroid®s, as well as publish to the SCADADroid® with any adjusted setpoints

MQTT Integration

  • Cloud-Based Broker service available for low monthly fees
  • Set up a third-party broker on the web browser configuration page
  • Configuration of Events allows for use of MQTT protocol in data reporting
  • Last known values preservation guarantees the survival of critical data
  • MQTT is encrypted via the message broker and does not need a VPN server to operate securely
  • Real values instead of percentages displayed through Modbus-driver tag upgrades
  • App Interface programs for streamlined MQTT-smartphone monitoring
