HD67G13-MSTP-G43-B2 – BACnet MSTP Master to HTTP/REST Client converter with SIM LTE

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

HD67G13-MSTP-G43-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 communicating through HTTP/REST. On the BACnet side, the device operates as a BACnet MSTP Master, so it can be used for data exchange with building automation devices working in this architecture. On the web communication side, the converter works as an HTTP/REST Client, enabling data to be sent to external servers, IIoT applications, reporting systems or integration platforms using REST architecture. The HD67G13-MSTP-G43-B2 variant is equipped with LAN + SIM LTE connectivity, so it can operate both in a local Ethernet infrastructure and in applications requiring cellular transmission. This model does not include eSIM or VPN service, so it is intended for installations where an RJ45 port and a physical SIM LTE card are required.

BACnet MSTP Master / HTTP/REST Client converter with LAN + SIM LTE

HD67G13-MSTP-G43-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, because the device can also be used in distributed facilities, measuring points, telemetry cabinets and installations where permanent access to a wired plant network is not available. As a result, HD67G13-MSTP-G43-B2 can act as a gateway between classic building automation and a modern application layer.

BACnet MSTP Master, HTTP/REST Client, Ethernet RJ45 and LTE module

The HD67G13-MSTP-G43-B2 operates on the automation side as a BACnet MSTP Master and on the external system side as an HTTP/REST Client. The device has 1 Ethernet RJ45 port used for HTTP/REST communication, configuration and network connection handling. 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 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-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. As a result, HD67G13-MSTP-G43-B2 helps connect classic building automation with modern HTTP/REST communication.

Configuration and diagnostics

The HD67G13-MSTP-G43-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 and later service support of the installation.
