MQTT IIoT Connector

Connect to MQTT devices and brokers with the built in MQTT Driver Interface


Product Overview

The OAS MQTT Data Connector allows you to connect to MQTT devices and software brokers with the built in MQTT Driver Interface.

OAS is also a MQTT Broker to allow read and write access to local and remote OAS Tag variables.


Broker Interface:

  • Subscribe to MQTT brokers to receive data.
  • Supports Sparkplug B protocol both as a Host Application and as an Edge of Network Node.
  • Publish data to MQTT brokers based on event, continuously, or data change.
  • Optionally include timestamp and data quality from originating source.
  • Optional timeout to verify broker is still alive.
