HD67G15-IP-G43-E-VPN-B2 BACnet IP Slave HTTP/REST converter with VPN

HD67G15-IP-G43-E-VPN-B2 BACnet IP Slave / HTTP/REST Client converter with VPN, LAN, SIM LTE and eSIM.

HD67G15-IP-G43-E-VPN-B2 is an industrial ADFweb converter designed to integrate systems operating as BACnet IP Slave with applications, servers and services using HTTP/REST Client communication. The device enables data exchange between a BACnet IP building automation network and an HTTP/REST-based environment, allowing BMS, HVAC, building control and technical supervision systems to communicate with web applications, reporting platforms, cloud services or external API servers.

The HD67G15-IP-G43-E-VPN-B2 version is equipped with an Ethernet RJ45 port, a SIM card slot, eSIM support, LTE connectivity and VPN Service. It is the most extended BACnet IP variant in this group, combining LAN communication, SIM LTE mobile access, eSIM functionality and VPN service in one compact DIN rail device. This makes the converter suitable for local installations, distributed technical facilities and projects where BACnet IP data must be transferred to HTTP/REST systems through either wired Ethernet or a mobile network.

BACnet IP Slave and HTTP/REST Client integration

The converter operates on the BACnet side as a BACnet IP Slave and on the Ethernet + LTE side as an HTTP/REST Client. This means that the device can expose BACnet objects to a BACnet Master system while communicating with HTTP/REST servers using GET and POST requests. Data can be mapped between BACnet objects and HTTP/REST request structures, simplifying the integration of building automation systems with API-based applications.

The device allows the user to define a list of HTTP/REST servers, configure endpoints, communication parameters, headers, request parameters and payload structure. Depending on the configuration, data can be read from an HTTP/REST server and made available on the BACnet side, or written from BACnet to HTTP/REST. This architecture is useful in projects where a BMS system has to exchange data with modern IT systems without replacing the existing automation infrastructure.

LAN, SIM LTE, eSIM and VPN Service

The HD67G15-IP-G43-E-VPN-B2 model supports communication via Ethernet and LTE mobile connectivity with both SIM card and eSIM support. The G43 variant indicates the presence of an LTE module with a SIM card slot, the E designation indicates integrated eSIM availability, and the VPN designation indicates the availability of VPN Service. This configuration gives the device a high level of flexibility in local and distributed installations, especially where a wired Internet connection is not available or where independent mobile connectivity is required.

On the BACnet side, the converter uses an RJ45 connector and 10/100 Base-T Autosensing data rate. On the HTTP/REST side, communication is available through RJ45 + SIM + eSIM, with 10/100 Base-T Autosensing for the Ethernet interface. This makes the device suitable for installations where communication must be adapted to the existing network architecture, mobile access conditions and project-specific requirements.

Configuration with SW67G15

The converter is configured using SW67G15 software. The tool allows the user to define HTTP/REST parameters, BACnet line parameters, the list of HTTP/REST servers, server endpoints and data mapping between the BACnet side and the HTTP/REST side. The software is also used to upload the configuration to the device and update the firmware when required.

The configuration includes IP addressing, DHCP, DNS, mobile network parameters, PIN, APN, operator credentials and activation of the physical SIM card or eSIM. For HTTP/REST communication, the user can define the client URL, request method, endpoint path, timeout, cyclic polling mode and the structure of data sent in RAW or JSON format.

Applications

• Integration of BACnet IP systems with HTTP/REST applications.
• Connection of BMS installations with web platforms and API servers.
• Transfer of building automation data to reporting and monitoring systems.
• Retrofit HVAC projects without replacing the existing BACnet infrastructure.
• Distributed technical facilities requiring SIM LTE or eSIM communication.
• Applications requiring a converter version with VPN Service.
• Energy monitoring, air conditioning, ventilation and building automation systems.
• Installations requiring LAN or mobile network connectivity.

Reliable operation in industrial and building automation environments

The HD67G15-IP-G43-E-VPN-B2 converter is designed for operation across a wide temperature range and for installations requiring stable communication between automation systems and network applications. DIN rail mounting simplifies installation inside control cabinets, while the 8..24V AC or 12..35V DC power supply range makes the device compatible with typical power systems used in building and industrial automation.

Thanks to the combination of BACnet IP Slave, HTTP/REST Client, Ethernet, SIM LTE, eSIM and VPN Service, this model is especially useful wherever BACnet IP data must be made available to external systems through an API or via a mobile network. It is a practical solution for system integrators, automation engineers and BMS designers looking for a converter for communication between building automation and HTTP/REST services.
