HD67G09-G43-B2 Modbus TCP Master to HTTP/REST Client converter with LTE

HD67G09-G43-B2 connects Modbus TCP Master devices with HTTP/REST Client communication via Ethernet and SIM LTE.

HD67G09-G43-B2 is an industrial ADFweb converter designed to integrate systems using Modbus TCP Master with applications and services based on HTTP/REST communication in client mode. This model has been developed for environments where industrial Ethernet communication must be combined with modern data exchange toward servers, software platforms and web services based on HTTP/REST architecture.

The HD67G09-G43-B2 variant offers LAN + SIM LTE connectivity, which means it can operate not only in a local network but also in distributed applications where mobile data access is required. It is a practical solution for automation integrators, telemetry systems, building installations and service applications in which data from a Modbus TCP network must be linked with HTTP/REST communication handled by a client.

The manufacturer confirms that the device provides electrical isolation between Ethernet and power supply, mounting on a 35 mm DIN rail, a wide power supply range of 12..35V DC / 8..24V AC and an operating temperature range of -40°C to +85°C. This specification makes the converter well suited for control cabinets and demanding industrial environments where stable operation, compact housing and simple installation matter.

The HD67G09-G43-B2 model is equipped with 1 Ethernet RJ45 port and a SIM slot for LTE connectivity. The manual states that the G43 version uses an LTE module, features an SMA Female antenna connector and works with a Micro-SIM card. The Ethernet port is used for device programming as well as for HTTP/REST and Modbus TCP communication, which simplifies device integration and commissioning.

From a network perspective, an important feature of the device is the use of two different MAC addresses: one dedicated to the HTTP/REST side and one dedicated to the Modbus TCP side. Communication on both sides works in the 10/100 Base-T Autosensing standard. The manufacturer recommends using at least a Category 5E cable compliant with the T568 standard, and the maximum Ethernet cable length should not exceed 100 m.

The converter includes four LEDs that indicate the operating status of the device. The first LED shows device state, the second indicates Modbus TCP communication activity, the third indicates HTTP/REST communication activity and the fourth shows error status. In addition, the module is equipped with a Recovery button, which allows the device to enter recovery mode after a wrong firmware update or configuration issue.

Configuration is performed using SW67G09, which allows the user to define HTTP/REST parameters, Modbus TCP settings, the list of accessible endpoints on the HTTP/REST side and the list of Modbus TCP read and write requests. The software is also used for device updates.
