HD67G13-MSTP-G43-E-VPN-B2 – BACnet MSTP Master / HTTP/REST Client with eSIM and VPN

HD67G13-MSTP-G43-E-VPN-B2 – BACnet MSTP Master and HTTP/REST Client integration with SIM LTE, eSIM and VPN.

HD67G13-MSTP-G43-E-VPN-B2 is an industrial BACnet MSTP Master / HTTP/REST Client converter by ADFweb, designed to integrate building automation devices operating in the BACnet MSTP standard with applications, servers and platforms using HTTP/REST communication. The device operates on the BACnet side as a BACnet MSTP Master, allowing it to exchange data with automation devices installed in building infrastructure, HVAC systems and BMS networks. On the web communication side, the converter works as an HTTP/REST Client, enabling data to be transferred to an external server, IIoT application, reporting system or higher-level platform using REST architecture. The HD67G13-MSTP-G43-E-VPN-B2 variant is equipped with LAN + SIM LTE + eSIM connectivity and VPN Service. It is the most extended version in this group, combining an RJ45 port, a physical SIM LTE card, integrated eSIM and remote communication capability through VPN.

BACnet MSTP Master / HTTP/REST Client converter with LAN, SIM LTE, eSIM and VPN

HD67G13-MSTP-G43-E-VPN-B2 enables BACnet MSTP communication to be connected with systems using data exchange through HTTP/REST. In practice, this means that data from building automation devices can be collected, processed and transferred to a web environment, external application or higher-level platform. The converter can be used to integrate HVAC controllers, regulators, meters, I/O modules, measuring devices, BMS installations and other technical infrastructure elements operating in the BACnet MSTP standard. On the application side, data can be sent to an HTTP/REST server, reporting system, cloud platform, telemetry solution or custom software prepared for a specific installation. SIM LTE connectivity and integrated eSIM increase deployment flexibility, while VPN Service supports remote communication, diagnostics and controlled service access. As a result, HD67G13-MSTP-G43-E-VPN-B2 is suitable for local installations, distributed facilities and technical points without permanent access to a wired plant network.

BACnet MSTP Master, Ethernet RJ45, LTE module, eSIM and VPN Service

The HD67G13-MSTP-G43-E-VPN-B2 operates on the automation side as a BACnet MSTP Master and uses HTTP/REST Client communication on the external system side. The device has 1 Ethernet RJ45 port used for network connection handling, configuration and communication with the higher-level system. According to the variant data, the BACnet connector and the HTTP/REST connector are implemented as RJ45, while the data rate for both BACnet and HTTP/REST communication is 10/100 Base-T Autosensing. The G43-E-VPN version uses an LTE module, a physical Micro-SIM card and integrated eSIM, while the antenna connector is SMA Female. When designing the installation, cellular signal quality, antenna selection and device mounting location inside an automation cabinet or field enclosure should be considered. The converter also provides electrical isolation between Ethernet and Power Supply, improving operating stability in technical and industrial environments.

BACnet MSTP data mapping to HTTP/REST communication

One of the key functions of HD67G13-MSTP-G43-E-VPN-B2 is the possibility to organize data exchange between the BACnet MSTP layer and the HTTP/REST communication structure. In a typical installation, the converter can handle data from BACnet MSTP devices and then transfer it to an HTTP/REST server in a way that matches the requirements of the receiving application. Such data may include temperatures, humidity, device operating states, alarms, regulator statuses, counter values, process parameters, input module signals or diagnostic information. On the HTTP/REST Client side, the device allows communication to be prepared for the specific data structure used by the higher-level system. This is especially important in projects where data from BMS or HVAC systems must be transferred to analytics tools, service applications, maintenance systems or cloud solutions. Thanks to the combination of SIM LTE, eSIM and VPN, this model can also be used where remote access to the installation is required in addition to data exchange.

Configuration and diagnostics

The HD67G13-MSTP-G43-E-VPN-B2 converter is configured using SW67G13 software. The program allows the user to prepare communication parameters on the BACnet MSTP Master side and on the HTTP/REST Client side, and then upload the configuration to the device. This allows the user to define how data is exchanged between the BACnet MSTP network and the system receiving data through HTTP/REST. The software is intended to run in an MS Windows environment. ADFweb diagnostic tools can be used to find the device in the network and check its IP address. This approach simplifies gateway commissioning in automation cabinets, Ethernet communication testing, LTE connection control, eSIM handling, VPN handling and later service support of the installation.
