MicroClarity MQTT Edge

Overview

MicroClarity MQTT Edge is a unified data hub that bridges the gap between industrial devices and MQTT-based applications. It connects to a wide range of data sources — including Allen-Bradley ControlLogix PLCs, Siemens S7 PLCs, Modbus devices, BACnet controllers, OPC UA servers, and other MQTT brokers — and exposes all of them through its built-in MQTT broker.

Each connected data source is represented as a Device in the MQTT topic hierarchy. Under each Device, you define nested Groups (for areas, subsystems, or functional blocks) and Items (for individual tags or data points). This hierarchy forms the MQTT topic structure, making it easy for MQTT clients to subscribe to exactly the data they need.

MQTT Edge uses on-demand device connections: if no MQTT clients are subscribed to a device's topics, MQTT Edge won't connect to that device. This reduces network traffic and device load, connecting only when data is actually needed. All data is published as JSON payloads, providing a simple, human-readable format for integration with analytics, historians, and cloud platforms.
