STjh OPC UA and MQTT FFU gateway with RS485, Ethernet, USB and antenna connections

STJH-FFU-BMS-GATEWAY-OPCUA-MQTT

FFU Gateway Modbus-to-OPC UA and MQTT

An industrial data gateway publishing Modbus FFU information through OPC UA or MQTT.

Modbus RTU field protocol
OPC UA and MQTT upstream options
Ethernet plant-data connection

Introduction de produit

This industrial IoT gateway connects the Modbus RTU FFU layer to server-based data platforms using OPC UA or MQTT over Ethernet. It is intended for semiconductor and advanced-manufacturing sites that need fan telemetry outside a conventional BMS. The upstream protocol choice differentiates it from Modbus TCP and BACnet IP building-control gateways.

Key Features

Server-oriented integration

FFU data can feed manufacturing or analytics platforms rather than only a building controller.

Two upstream protocols

OPC UA supports structured industrial access, while MQTT supports broker-based telemetry.

Separated field network

Existing Modbus fan devices remain on their RS485 segment.

Applications

Suitable for semiconductor and advanced-manufacturing sites integrating FFU telemetry with plant historians, dashboards or data platforms. Topic, namespace and point mappings should be defined before deployment.

Solutions for Your Application

FFU telemetry remains isolated inside the building-controls layer.Expose mapped Modbus data through OPC UA or MQTT to the plant platform.

Unstructured tags make long-term data difficult to use.Define stable namespaces, topics and equipment identifiers before publishing.

Options disponibles

Choose OPC UA, MQTT or both; define security, broker or server details, point map and Ethernet settings. Confirm data ownership and write permissions.
