HD67G13-MSTP-G43-VPN-B2 – BACnet MSTP Master / HTTP/REST Client with SIM LTE and VPN

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

HD67G13-MSTP-G43-VPN-B2 is an industrial 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, so it can handle data exchange with field automation devices working in this architecture. On the web communication side, the converter works as an HTTP/REST Client, allowing data to be transferred to an external server, IIoT application, reporting system or higher-level platform using REST architecture. The HD67G13-MSTP-G43-VPN-B2 variant is equipped with LAN + SIM LTE connectivity and VPN Service. This model does not include eSIM, so it is intended for installations where an RJ45 port, a physical SIM LTE card and remote communication through VPN are required.

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

HD67G13-MSTP-G43-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 increases deployment flexibility, while VPN Service supports applications requiring remote communication, diagnostics or more controlled service access. As a result, HD67G13-MSTP-G43-VPN-B2 is suitable for local installations, distributed facilities and technical points where wired communication is not always available.

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

The HD67G13-MSTP-G43-VPN-B2 operates on the automation side as a BACnet MSTP Master and uses HTTP/REST 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-VPN version uses an LTE module and a physical Micro-SIM card, 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-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 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 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-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 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, VPN handling and later service support of the installation.
