HD67C27-G43-VPN-B2 PROFINET Master MQTT Broker converter with LTE and VPN

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

HD67C27-G43-VPN-B2 is an industrial PROFINET Master and MQTT Broker converter designed to move PROFINET data into modern IIoT architectures while adding a practical security layer through the built-in VPN service. The G43 version provides LAN and LTE connectivity using a micro-SIM, making this device a strong fit for distributed sites, remote cabinets, and installations where fixed wired uplinks are limited or unavailable.

In real deployments, HD67C27-G43-VPN-B2 helps you standardize OT to IT data delivery. PROFINET values can be published through MQTT to SCADA, dashboards, analytics, maintenance platforms, on premises servers, or cloud systems. VPN support is particularly valuable when the project requires controlled remote access and secure communication paths across multiple locations in Poland and the EU.

Key benefits of HD67C27-G43-VPN-B2

• PROFINET Master and MQTT Broker in one device for clean PROFINET data distribution via MQTT topics.
• VPN service for projects where secure remote connectivity and controlled access are required.
• LAN + LTE micro-SIM connectivity for hard-to-wire sites and distributed infrastructures.
• Industrial robustness with electrical isolation between Ethernet and power supply, DIN rail mounting, and wide power input range.
• Wide temperature range for harsh environments, supporting reliable operation from -40C to +85C.

Typical applications

This model is commonly used in production lines, OEM machinery, utilities, and infrastructure monitoring where PROFINET data must be integrated into MQTT based systems. LTE helps keep the data stream alive in remote locations, while VPN supports security requirements for remote supervision, service access, and controlled connectivity across sites.

Configuration and commissioning

Configuration is performed using the Windows software Compositor SW67C27. It enables defining MQTT parameters, PROFINET line parameters, the list of allowed MQTT clients, MQTT topics published and subscribed from or 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. Use at least Category 5E cabling (maximum 100 m) and standard T568 wiring for 100 Mbps links. The interface provides one MAC address for MQTT and one MAC address for PROFINET.

The LTE antenna connector is SMA Female, so the antenna must have an SMA Male connector. The physical SIM card type is micro-SIM. If recovery is needed after a firmware update issue or a configuration problem, press the recovery button and access the device via the default IP address 192.168.2.206 using the webserver in Recovery Mode.

For MQTT payload creation, a template string can be used. In basic mapping, the keyword $VALUE$ is replaced by the real value coming from or going to PROFINET. Advanced mapping can include multiple variables using dedicated keywords within the template.
