EtherNet/IP Slave and MQTT Broker converter with LAN and LTE connectivity HD67C16-G43-B2

Advanced EtherNet/IP Slave and MQTT Broker converter with integrated LAN and LTE connectivity.

The HD67C16-G43-B2 is an industrial protocol converter designed to enable reliable data exchange between EtherNet/IP Slave networks and systems based on the MQTT Broker communication model. The device acts as a bridge between industrial automation environments and modern IT or cloud-based infrastructures.

On the industrial automation side, the converter operates as an EtherNet/IP Slave, allowing PLCs, SCADA systems and controllers to access and exchange process data in a deterministic way. On the communication side, the integrated MQTT Broker functionality enables publishing and subscribing of data over Ethernet and LTE networks, supporting distributed and remote installations.

Main application areas

The HD67C16-G43-B2 is intended for industrial IoT architectures, remote monitoring systems, and automation solutions where EtherNet/IP-based devices must be integrated with MQTT platforms. Typical applications include factory automation, process monitoring, energy management systems, and modernization of existing EtherNet/IP installations without changes to PLC programs.

Hardware features and industrial design

The converter is built into a compact housing type B designed for 35 mm DIN rail mounting. It is equipped with screw terminal connectors and an integrated LTE module with SIM card slot, enabling communication in installations where wired Ethernet access is limited or unavailable. Electrical isolation between Ethernet and power supply ensures stable operation in industrial environments.

• EtherNet/IP Slave communication via RJ45 Ethernet interface
• MQTT Broker communication over Ethernet and LTE networks
• Wide power supply range for industrial control cabinets
• DIN rail mounting for fast and secure installation
• Industrial operating temperature range from -40°C to +85°C

Configuration and software

The HD67C16-G43-B2 is configured using the dedicated SW67C16 software provided by ADFweb. The software allows configuration of EtherNet/IP parameters, MQTT Broker settings, definition of published and subscribed topics, management of allowed MQTT clients, and firmware updates. Configuration is performed offline and does not require any changes to the PLC application.

The configuration software SW67C16 is available for download directly from the manufacturer website: https://www.adfweb.com/download/filefold/SW67C16.zip
