HD67C27-G43-B2 Industrial PROFINET Master to MQTT Broker converter with LTE SIM and LAN

HD67C27-G43-B2 PROFINET Master and MQTT Broker Converter (LAN + SIM LTE)

HD67C27-G43-B2 is an industrial PROFINET Master and MQTT Broker converter designed to bridge PROFINET data into modern IIoT architectures. With LAN and integrated LTE connectivity via micro-SIM, this model is ideal for distributed sites where you need stable telemetry, remote visibility, and a scalable MQTT data layer without relying on fixed wired infrastructure.

In practice, HD67C27-G43-B2 enables collecting process and diagnostic data from PROFINET and delivering it through MQTT to SCADA, maintenance platforms, on premises servers, or cloud applications. It is a practical choice for factories, OEM machinery, utilities and building infrastructure projects across Poland and the EU where OT data must be integrated into IT systems in a structured, future-proof way.

Key benefits of HD67C27-G43-B2

• PROFINET Master and MQTT Broker in one device for direct PROFINET to MQTT integration.
• LAN + LTE micro-SIM connectivity for remote cabinets, mobile installations, and hard-to-wire sites.
• Electrical isolation between Ethernet and power supply to improve robustness in industrial environments.
• Wide supply range (8..24V AC, 12..35V DC) and wide temperature range (-40°C to +85°C).
• DIN rail mounting in housing type B (Modulbox 4M) for fast installation in control panels.

Typical applications

HD67C27-G43-B2 is commonly used in production lines, OEM machines, infrastructure monitoring and distributed sites where PROFINET data needs to be published via MQTT for analytics, alarms, dashboards or reporting. LTE connectivity helps maintain continuity of data flow in locations without a permanent Ethernet uplink, while MQTT provides an efficient, scalable model for system integration.

Configuration and commissioning

Configuration is done using the Windows software Compositor SW67C27. It allows you to define MQTT parameters, PROFINET line parameters, the list of allowed MQTT clients, MQTT topics published and subscribed from/to PROFINET slaves, the list of topics forwarded via the internal bridge, and device update operations.

Software: SW67C27

The Ethernet port is used for device programming and for MQTT and PROFINET communication. For commissioning in a cabinet, use at least Category 5E cabling up to 100 m and standard RJ45 connectivity. The LTE antenna connector is SMA Female, so the antenna must have an SMA Male connector, and the physical SIM type is Micro-Sim. If recovery is needed after a firmware or configuration issue, the device can be accessed via the default IP address 192.168.2.206 through the webserver in recovery mode.
