Description

Modbus to MQTT Gateway

Control Solutions’ Babel Buster MQ-61 Modbus to MQTT Gateway turns any Modbus device into a Thing on the Internet of Things. The MQ-61 will poll one or more Modbus RTU and/or Modbus TCP devices, collecting data from the list of registers you provide. Based on rules you create, the MQ-61 will decide if and when to publish that data to the MQTT broker (server). You can also configure the MQ-61 MQTT client to subscribe to data coming from the MQTT broker, which you can then write out to Modbus devices to manage setpoints and the like.

Mosquitto MQTT Support

The MQ-61 MQTT client works well with the widely used open source community supported Mosquitto MQTT broker available at https://mosquitto.org. Simply turn off features unique to ThingsBoard or AWS IoT when using Mosquitto MQTT.

ThingsBoard Support

The MQ-61 MQTT client includes support for ThingsBoard’s unique MQTT API that allows you to connect your Modbus registers to dashboard widgets such as gauges, knobs, buttons, and charts. Learn more about ThingsBoard here.

AWS IoT Support

The MQ-61 includes everything necessary to connect to Amazon Web Services (AWS) IoT support using MQTT. Once the IoT connection is made, your Modbus data can make its way to an AWS database, AWS notification services (e.g. email alerts, text messages), and a variety of analytics tools including QuickSight which makes it quite easy to quickly graph your data.

Cloud Not Required!

The MQ-61 is also suitable for stand-alone remote monitoring use. The MQ-61 includes alarm monitoring with email notifications using its internal secure email client, local data logging with CSV files emailed to you instead of sending data to the cloud, and a real time scheduler for date and time scheduling.
